What structures should be considered in the design of injection molds?

The success or failure of plastic processing lies to a very large extent in the effect of injection mold design and the quality of injection mold manufacturing, and the injection mold design is based on the correct design of plastic products. 

So what structures must be taken into account in the design of injection molds? The following GonSon injection mold manufacturer's editor to give you a group of detailed introductions, the details are as follows.

Injection mold

1. parting surface: that is when the injection mold closed cavity and mold seat with each other to touch the surface. Its parts and the way of selection, subject to product appearance and appearance. 

Wall thickness. Forming method. Post-production process. Injection mold type and structure. The hazards of the way out of the mold and the structure of the molding machine and other elements. 2.

2. structural parts: i.e. the complicated injection mold guide slider. Oblique guide pillar. Straight top block, etc. The design of the structural parts is very important, which is related to the service life of the injection mold. Production and processing cycle time. Cost. 

Therefore, the design of the key structure of the injection mold is very important to the designer's comprehensive ability, so that he can pursue perfection and simplicity. More durable. More economic development of the program design. 3.

3. mold accuracy: that is, card avoidance. Precise and accurate positioning. Positioning pin. Card spring, etc. 

Cell phone positioning system is related to the product appearance quality, injection mold quality, and service life, according to the injection mold design is different, pick different precision positioning methods, precision level manipulation key with the help of production processing, core mold precision positioning is mainly the designer enough to take into account, design a more effective and easy to adjust the precision positioning method.

4. pouring system: that is, from the plastic machine nozzle to the middle of the concave mold into the material safety channel, including the popular channel. 

Separation channel. Inlet and cold material cavity. 

Especially the selection of the inlet part should be beneficial to the molten plastic in the case of excellent liquidity to fill the concave mold, the solid overflow channel attached to the product and the cold material in the inlet is easy to be ejected from the mold and given to eliminate when leaving the mold.

5. the plastic shrinkage rate and its various elements endanger the dimensional accuracy of the product, such as mold manufacturing and installation deviation. 

Mold damage, etc. In addition, the design of press molds and injection molds should also take into account the pairing of the main parameters of the processing and structure of the molding machine. Injection mold design has been widely used in auxiliary design technicality. 

In addition, the injection mold should also take into account the mold standard parts in the design process, so that the full set of mold can achieve the best effect, and then promote the injection mold in the injection mold processing stage can be carried out smoothly.
