Car ventilation cap injection mold design
Abstract
The topic of this design is the injection mold of the automobile ventilation cover. Plastic parts are determined using polypropylene (PP) as material. The material has good insulation, good mechanical properties, low price, etc., and is the lightest of general-purpose plastics and better applicable in car lighting ventilation cover manufacturing. This design uses the CAD, PROE, and so on many kinds of design drawing software to carry on the computer software aided design to the automobile ventilation cover, which makes the design and production of the plastic part more efficient and comprehensive. The design of the parting surface is a single injection mold parting surface, cavity using a mold sixteen cavity. The gate of plastics by submarine gate injection, the core with combined type core design, launched in the form of a rod plate pushing mechanism to complete the plastic parts to launch.
This paper has 16 figures, 4 tables, 22 references.
