As the plastic industry, plastic injection mold design and processing has become an important method of processing plastic products. This design is the Qirui car bumper lamp holder of the injection mold. This design from the choice of topics based on significance and its current development status and prospects of starting, after a lamp on the Qirui car bumper plastic shape, size and other structural analysis and the actual production conditions and the existing processing technology understanding to choose reasonable Plastic materials, selected injection molding machine, determine a reasonable injection mold. The specific design of injection mold include: mold parting surface, the cavity number and layout of the established model of the body wall and the concave and convex type core size calculation, casting, mold release, ejector, guide, reset, row overflow entraining, temperature regulation, and system design and calculation. As the Qirui car bumper lamp plastic surface of the lateral hole, so this also for the plastic parts of the structure, design a unique side core pulling. Part of the design basis of the above, the results to design the structure of the overall structure of mold. Pursuant to these parts of the final design, integration design calculations Qirui car bumper lamp plastic injection mold the overall structure.
Key words: Injection mold; Sub surface; Embossing mold; Side core pulling
