Title      motorcycle handle cover injection mold design  

Abstract Abstract ：The main topic covered for motorcycle handle cover injection mold design, the cover materials is PA1010, is commonly found in industrial production of a protective cover products. Through the process of plastic parts for analysis and comparison, the final design of an injection mold. The product mix from technology issues, and specific mold structure of the casting mold system, mold forming part of the structure, side pumped body, top of the system, cooling system, the choice of injection molding machine and related calibration parameters are detailed design, at the same time and developed a simple process dies. Through the entire design process that the mold can be achieved by the plastic parts processing requirements. Designed in accordance with the subject's main task is to build a round plastic injection mold design, that is, the design of an injection mold to produce plastic products in order to achieve automation to increase production. Plastic parts for the specific structure of the mold is the spokes-style single-gate injection mold surface.
