The plastic die designing of cicrcle
Abstract
The requirement, content and direction of the design of the shell plastic parts are embodied on this injection mould design of the plastic parts of encloser. The designer’s foundation knowledge of the injection mould design is reinforced and is able to design more complex injection mould through the design.
The molding process of plastic parts, the effect analysis to plastic parts quality caused by molding structure, as well as the casting system design, partial and general design of mold moulding introduced respectively. The critical points of mold for plastic design are introduced, and the adjustable character of molding structure、exchange character as well as the molding costs are all considered farther. Starting from controlling dimensional accuracy, the carry the cover to the main dimensions of injection molding are carried out so as to determine the size of different parts, the molding design and the process of parts as well as assembling process and etc of injection molding are stated in details.

Key words:process analysis; plastic parts moulding; casting system; molding structure;
