The Base Four-wheel Toys Molding Process and Mold Design
Abstract：Mold plays a huge role in modern industrial production,Has a very wide range of molds quickly, the pace of development in recent years to account for a large position in the mold industry. Study injection molds for the plastics production process and improve the plastics product quality has a lot of design, toy four-wheel base molding process and mold design, injection mold design process. Plastic structure analysis of the process and the use of materials, process analysis, mold design, introduced the design of the choice of method of injection molding machines, gate, cold discharge port, and exhaust ducts, and also gave details of the cavity to determine the number of methods, parting surfaces, lateral pulling mechanism, the design principles of the guiding mechanism of mold, mold release, institutions, cooling this design, injection mold development and design methods can have a basic understanding of to notice the details in the design process to understand the mold structure and working principle.
Key words：base of four-wheel toys、molding process、mold design、injection mold
