Therefore, the research casts the mold to understand the plastic product the production process and improves the product quality to have the very big significance. This design introduced the injection takes shape the basic principle, specially single is divided the profile to inject the mold the structure and the principle of work, to cast the product to propose the basic principle of design; A set of mould with one module and two cavities has been designed through he flow around the right boards sent technology analysis. The design and machining technology process of its molding part including the front molding plate、front mould kernel、back mould plate、back mould kernel、back mould set piece、incline guide pin、slide steatite etc, and the choice and calculation of technology parameters of the impotent part, the design process of extrusion outfit, inject system and other makeup are specified in detail; integrated approach to the appearance of a good product demand and gate location and the way the problems between Remolding, Test and product have been introduced.
