This paper mainly introduces the Dongan lock buckle hand pull mold design, plastic injection molding process, as well as the process of injection molding machine also carried out a number of brief. The main injection mold design process are: process analysis of plastic products, to determine the number of cavity, the choice of injection molding machine, as well as the structural design of mold. The structural design of mold include: the design of gating system, forming part design, design-oriented, Demoulding design, cooling design and exhaust system design. This article is designed to mold a three-plate mold cavity. Food basket due to the special shape, the mold sets out through the top of the differential, the paper of the various parts of the mold parts to the design and calculation. In this paper, the working principle of the mold and the work process, as well as the use and maintenance of molds are also described. In this paper, detailed design and assembly process.
