Pump cover injection mold design

Abstract Under the rapid development of modern industry, plastics industry also formed the rapid changes and the corresponding requirements for the design of injection mold is also getting higher and higher, the production to ensure product quality, in the industrial area of the manufacturing accuracy is an important, so as far as possible to improve product accuracy, shorten the production cycle to improve production efficiency. This is very important for the development of enterprises. Mold technology is a comprehensive discipline, it includes a lot of disciplines, such as CNC, computer, machinery, etc..

In this paper, the design of the structure is the pump cover injection mold, the design involves many plastics molding process. This paper makes a detailed explanation. Is mainly to design reasonable parts, the application of the pouring system, also equipped with a reasonable cooling, when the production is finished, complete the appropriate release, which comes with many CAD drawings, to facilitate better analysis of die structure.

Key words: injection mold gating system cooling system mold release
