Abstract: In this paper, the structural manufacturability of special-shaped composite products was introduced by using the plastic robot products as carriers, and the forming scheme of one mold with many different cavities was determined. Based on the CAE numerical simulation technology, the design of the mold gating system was optimized to resolve the unbalanced filling problem occurring in the flow passage. Meanwhile, a special structure was additionally arranged on the runner to solve the problem of space storage for the products after injection molding production. According to the functional requirements of the products, a core pulling mechanism was arranged in the mold to solve the technical problem of thread clamping after the product was formed. The mold achieved good results in the actual production process. This work provided a good reference for the design of similar molds.
