The product mix fromtechnology issues, and specific mold structure of the casting mold system, moldforming part of the structure, the roof system, cooling system, the choice ofinjection molding machine and related calibration parameters, there aredetailed design, at the same time and simple preparation of the mold process.Through the entire design process that the mold can be achieved by the plasticparts processing requirements. According to the subject of the main tasks ofdesign wear sets of injection mold design. That is, the design of an injectionmold to produce plastic parts wear sets of products, increase production inorder to achieve automation. copyright paper51.com Keywords: Banana-type gate, injection mold, flow channel paper51.com 摘 要................................................................................................................................
