Design of injection mold for forming process and the door hook
Abstract: the plastic industry is one of the fastest growing in the world today, and the injection mold is one of the types of rapid development, therefore, study to understand plastic injection mold production process and improve the quality of products have great significance. This paper discusses the design method of using UG, CAD computer aided design of injection mold for the door hook. Describes the basic principle of injection molding especially the structure and working principle of single injection mold parting surface, put forward the basic design principles of injection molding products; products using materials for PBT+GF20. Injection molding is one of the main methods of thermoplastic plastic molding, molding can be a complex shape of precision plastic parts. The design of the injection mold design of the door hook, the structure of parts of the process analysis. The parting surface, gating system have been determined, the choice of injection machine, has calculated the formation spare part size. The side gate, using straight guide column, putting the pieces to complete the release. So the structure is designed to ensure reliable mould work. Matching the mold structure and the injection machine is checked. And a set of AUTOCAD drawing die assembly drawing and parts drawing. Through this design, can have a preliminary understanding of the injection mold, pay attention to the details of the design, the die structure and working principle of understanding.
Keywords: injection mold; process analysis; gating system; forming parts.
