Figure 1 shows the parts of a high-precision product of our company - the basic block, the material is modified polyphenylene ether. The part has the following structural features due to its important role in the product: complex shape, thin wall thickness of 2.75 Mm, especially for the four side walls, is designed with through holes and dovetail slots. The product is a patch screen structure, and the entire screen is formed by splicing a number of basic blocks. Therefore, when the product is assembled, the basic blocks are spliced ​​together. Whether the dimensional accuracy and shape tolerance of plastic parts can meet the design requirements is the key to ensuring product quality. In this paper, process analysis and mold design are carried out on how plastic parts are injection molded and their dimensional accuracy is guaranteed.
