Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to an injection mold head component of a sole injection molding machine. Background Art

[0002] The structure of traditional shoes such as leather shoes, sports shoes and the later polyurethane upper injection-molded shoes generally includes an upper, an insole, a midsole and an outsole. The upper and the outsole are connected to form a shoe body. The midsole and the upper of the polyurethane upper injection-molded shoes are sewn together and then placed on a mold. The foaming liquid material is injected into the mold to form the shoe body. The sole injection molding device generally has the upper surface tied to an aluminum last, and then PVC, TPR and other materials are directly injected by a turntable machine to form the sole in one go. Nowadays, there is also PU (chemical name polyurethane) injection molding. The mold requires different designs due to different materials. Among them, molds of several main materials such as RB, EVA, and TPR are the most widely used.

[0003] In the process of sole injection molding, the die plays a key role in product quality. Its function is to make the extruded molten material pass through the die section evenly. The sole die is adapted to the requirements of the extruded product and plays a decisive role in the work efficiency and economy of the entire production line. The existing die structure is fixed, difficult to disassemble and clean, and has poor adjustability. In order to solve the shortcomings of the existing technology, we propose an injection die component for a sole injection molding machine. Utility Model Content
