Precautions for selection of ejector pin of plastic mould

Today, Yize mould shares with you a knowledge point that mould people must master -- precautions for selection of ejector pin of plastic mould.

Ejection system is one of the important functional structures of injection mold. It consists of a series of ejection parts and auxiliary parts, which can have different ejection actions. Ejector pin class is the most commonly used ejection method. Thimble type ejection components, including round ejector pin, shoulder ejector pin, core blade ejector pin, push tube. Precautions for selection of ejector pin of plastic mould are as follows:
1. Prevent the deformation or damage of the plastic part, correctly analyze the size and position of the adhesion of the plastic part to the mold cavity, and select the appropriate demoulding device to make the top force applied to the part with the largest rigidity and strength of the plastic part, that is, the top force should be on the wall as far as possible, under the bone position and column position, and the action area should be as large as possible (that is, the ejector pin with the largest diameter should be selected as far as possible) to prevent the deformation of the plastic part Or damaged.  

2. The structure shall be reasonable and reliable, the ejector mechanism shall be reliable in operation, flexible in movement, convenient in manufacture, easy to replace and have sufficient strength and rigidity.yizali2li

3. When the diameter of the ejector pin is below φ 2.5 and the position is enough, the shouldered thimble shall be made; when the push pipe wall is below 1mm or the push pipe wall diameter ratio is ≤ 0.1, the shouldered push pipe shall be made, and the fixed part shall be as large as possible. The effective matching length of thimble = (2.5-3) d, the minimum should not be less than 8mm, we generally take 20-25mm in the manufacturing process.

4. The ejector pin shall not be placed at the joint of the insert as far as possible

5. For the long arc glue position above 10 mm high, it is recommended to use flat thimble. The shorter the flat body is, the better the strength is, and the easier the processing is. The length of the cylindrical part shall be indicated in the design specification; for the pipe column with the height of more than 10 mm, it is recommended to push the pipe out.

6.In case of inclined thimble, in order to prevent the product from sliding with the inclined thimble, the "+" slot shall be ground on the thimble surface near the inclined thimble.

Do you pay attention to mold maintenance?

As we all know, regular maintenance of the mould can keep its best performance state and prolong its service life, so as to ensure the normal production. Do you pay attention to mold maintenance? Let's take a look at how to maintain the mold:

First of all, each mold should be equipped with inspection and maintenance table to record and count its use, care and damage, and then judge which parts and components have been damaged and the degree of wear, so as to provide information for finding and solving problems.

Secondly, under the normal operation of the injection molding machine and the mold, test the various properties of the mold, and measure the size of the final molded plastic parts. yize86ka Through these information, we can determine the existing status of the mold, find out the damage of the cavity, core, cooling system and parting surface. According to the information provided by the plastic parts, we can judge the damage status of the mold and the maintenance measures.  
At the same time, several important parts of the mold should be tracked and tested: the ejecting and guiding parts are used to ensure the opening and closing movement of the mold and the ejecting of the plastic parts. If any part is stuck due to damage, it will lead to production suspension. Therefore, the lubrication of the die thimble and guide pillar should be kept regularly (the most suitable lubricant should be selected), and the deformation and surface of the thimble and guide pillar should be checked regularly Once the damage is found, it shall be replaced in time; after a production cycle, the working surface, moving and guiding parts of the mould shall be coated with professional antirust oil, especially the protection of the elastic strength of the bearing part of the mould with gear and rack and the spring mould shall be paid attention to, so as to ensure that it is always in the best working condition; With the continuous production time, the cooling channel is easy to deposit scale, rust, sludge and algae, which makes the cross section of the cooling channel smaller and the cooling channel narrower, greatly reduces the heat exchange rate between the coolant and the mold, and increases the production cost of the enterprise. Therefore, attention should be paid to the cleaning of the channel; For hot runner mould, the maintenance of heating and control system is helpful to prevent production failure, so it is particularly important. Therefore, after the end of each production cycle, the belt heater, rod heater, heating probe and thermocouple on the mold shall be measured with ohmmeter. If they are damaged, they shall be replaced in time, compared with the mold resume, and records shall be made so that problems can be found in time and countermeasures can be taken.
In addition to the regular maintenance of the mold, the daily cleaning and maintenance can not be less, which can not only improve the service life of the mold, but also save the production cost and improve the production efficiency to a certain extent, so we must do a good job in daily maintenance and regular maintenance!
The above is the mold maintenance method summarized by Yize mould for you. You can contact us to purchase mechanical mold parts,  plastic mold components, stamping mold parts and other precision mold parts, and we will wholeheartedly provide services for you~

About the importance of EDM processing

With the continuous development of science and technology, market competition requires shorter and shorter manufacturing cycle of mold parts, and the continuous improvement of precision of mold parts of industrial products requires more and more precision of dies. At this time, the importance of EDM processing becomes increasingly obvious.

Spark machine is a kind of mechanical equipment used in EDM. It is a special processing method to remove conductive materials by using the electric erosion effect produced by the pulse discharge between the two poles immersed in the working fluid. yize86ka It is also called EDM or erosion processing. The importance of EDM processing is getting more and more attention.

EDM machining is mainly used to process dies and parts with complex shaped holes or cavities, such as hard and brittle materials such as carbide and quenched steel, deep and fine holes, special holes, deep grooves, narrow slots and thin slices, and tools such as forming cutters and thread rings.

It is understood that in the current mold production, about one third of the processing work is completed by EDM, which shows the importance of EDM processing.

Common methods about polishing of precision mold components

For small parts such as precision mold components, every processing procedure needs to be careful, otherwise,mold parts may be scrapped. For example, polishing of precision mold components.

How do we make every small mold accessory smooth and beautiful, and how do we make this polishing process? Next, YIZE MOULD yize86ka will introduce six methods about polishing of precision mold components.

1. Mechanical Polishing
Mechanical polishing is a polishing method to get smooth surface by cutting and plastic deformation of material surface to remove the convex part after polishing.

2. Chemical Polishing

The main advantage of this method is that it can polish complex workpieces without complicated equipment.

3. Electropolishing

Compared with chemical polishing, the effect of cathodic reaction can be eliminated and the effect is better.

4. Ultrasound Polishing

Ultrasound processing has small macro force and will not cause workpiece deformation, but it is difficult to manufacture and install the tooling.

5. Fluid Polishing

Fluid polishing relies on high-speed flow of liquid and abrasive particles to wash the surface of precision mold components to achieve polishing purposes.

6. Magnetic Abrasive Polishing

This method has high processing efficiency, good quality, easy control of processing conditions and good working conditions.

Although polishing of precision mold components is a simple and common processing step, different methods can be selected according to the differences of workpieces in order to achieve good results.

Prospect of core pins and sleeves processing industry

In recent years, due to various reasons of the mould industry, the development of the core pins and sleeves processing industry is facing many difficulties. We first analyze the positioning of the mould in the whole manufacturing industry, and then we will know its prospects.

Development expectation of core pins and sleeves processing industry：
Firstly, the external environment, which has to be considered. Economic recovery is only a matter of time. There is nothing to worry about, and then there will be a series of measures to stimulate the economy. As long as China's economy remains at about 8% per year, there will be nothing to worry about in the manufacturing and core pins and sleeves processing industry.

Then there is the internal environment. After these years of brutal competition, many core pins and sleeves processing factories fail and survivors naturally have their own way to survive. Either they have stable customers, strong business or high quality. Such a company, once the external environment improves and business volume increases, yize86ka the increase in profits can be expected.

Mould industry is still promising, because it is the two core of manufacturing industry after all, especially when the two core began to merge into a core, another golden age is coming! Even if it is really depressed and difficult, we can not deny the industry! Especially in such a basic industry.

The core pins and sleeves processing industry is always an industry that depends on technology and quality!

About the processing quality of connector mold parts

With the development of processing technology, the industry's requirements for processing quality are also improved. How should we improve the processing quality of connector mold parts? Let's discuss it today.

Processing quality of connector mold parts includes machining accuracy and surface quality: Machining accuracy is the conformity of three geometric parameters of actual size, shape and position of the machined part surface with the ideal geometric parameters required by the drawings; Machining accuracy and machining error of die parts are both to evaluate the geometric parameters of machined surface. Terminology.

Machining accuracy is measured by tolerance grade. The smaller the grade value, the higher the accuracy. Machining error is expressed by numerical value. The larger the value, the greater the error. High processing accuracy means small processing error and vice versa.

The quality of the machine greatly affects the processing quality of the connector mold parts. The processing quality of the parts includes two parts: the processing accuracy and the surface quality. yize86kaThe machining accuracy refers to the degree to which the actual geometric parameters (size, shape and location) of the parts after processing conform to the ideal geometric parameters.

About the characteristics of plastic mold spare parts

Today let's take a look at the characteristics of plastic mold spare parts.

Generally speaking, the characteristics of plastic mold spare parts include the following three:
1.High temperature performance
When the working temperature of plastic die parts is higher, the hardness and strength will decrease, leading to early wear or plastic deformation of the die and failure. Therefore, the die material should have high temper resistance stability to ensure that the die has high hardness and strength at working temperature.

2. Cold and thermal fatigue resistance

Some moulds are in the state of repeated heating and cooling in the working process, which makes the surface of the cavity subject to tension and pressure variable stress, causes surface cracking and peeling, increases friction, hinders plastic deformation, yize86ka reduces dimensional accuracy, and leads to die failure. Thermal and cold fatigue is one of the main failure modes of hot working dies, and the die should have high cold and thermal fatigue resistance.

3. Corrosion resistance
Some parts of plastic mould, such as plastic mold spare parts, exist chlorine, fluorine and other elements in the plastic. After heating, they decompose and precipitate strong corrosive gases such as HCI and HF, which erode the surface of the mould cavity, increase its surface roughness and aggravate wear failure.

The above is about the characteristics of plastic mold spare parts, if you want to know more information, please follow YIZE MOULD!
