Abstract
This topic mainly aimed at the mold design of plastic lid。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，the roof system，cooling system，the choice of injection molding machine and related calibration parameters，there are detailed 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 plastic parts processing requirements。Designed in accordance with the subject's main task is the design of injection mold lid。 That is，the design of an injection mold to produce plastic parts lid products， increase production in order to achieve automation。 For the specific structure of the lid， the mold is the point of the dual－gate injection mold surface。 Because there are four plastic parts inside a small boss， solid slider using the activity of the structure。 The advantage lies in simplifying the corporate structure which will enable to reduce mold shape， greatly reducing the manufacturing costs of the mold。 Through the mold die design that the lid can achieve the quality and processing requirements。
