What Should Be Paid Attention To in The Design And Processing Of Automobile Injection Molds

At present, the demand for plastic parts in the automotive industry is increasing day by day. In other words, the quality of plastic parts has a major role in promoting the development trend of the automotive industry. Therefore, the quality of plastic parts is particularly important, and injection molding determines the quality of plastic parts. Therefore, G efficiency is required to improve the quality of injection molds, and the design scheme of automobile injection molds is the basis for improving the quality of molds.

1.1 The design scheme of plastic products is the key

Plastic product design is a key stage in the design of automotive injection molds. For the design of plastic products, it is necessary to simplify the plastic product model as much as possible.

Simplified design scheme is a requirement clearly put forward for each optimization stage of plastic products. In this requirement, the basic requirements of important links are basically considered, such as the thickness design scheme of automobile injection mold, try to make the thickness of the mold as symmetrical as possible to prevent inconsistency. Appropriately thick and thin glue positions appear.

with basic requirements for parts

In terms of compressive strength and strength, a D specification should be achieved, otherwise it will not be able to withstand friction, which will endanger the construction quality. After the product is formed, it needs to make its surface glossy, which can be done by grinding and polishing.

1.3 Select the parting line and parting surface of automobile injection mold

The clear method of the parting line can be determined according to the appearance of the part. The function of the fractal line is to divide the product into two parts, and the boundary line is the same. It is divided into two parts, which are located in the fixed mold, and the other part is formed by the movable mold. To obtain the parting surface of the automobile injection mold, the fractal line can be used, and the parting surface of the mold can be determined by using the fractal line scanner around the mold at multiple places.

1.4 Frequently Asked Questions about Parting Surface Design Scheme

There is a point B on the parting surface of the automobile injection mold that must be paid attention to, that is, to ensure that each same slope has a sealing distance, and B must ensure the effectiveness of the distance, so that the plastic solution can be made in the whole process of injection. Loss, the name of the sealing material spacing is matched by this efficiency, which can seal the material. In the whole process of the establishment of the parting surface, if you encounter a parting surface with a large difference in aspect ratio such as a slope or a slope and its steps, whether it is one or several, be sure to set a standard plan for it, which can be beneficial to Production processing and measurement.
