摘要:摄影仪外壳分为上下壳 ,塑件结构较为复杂壳体。根据产品的数量和塑料零件的成形工艺性能确定了:上壳以单分型面注塑模的方式进行设计。模具的型腔采用一模一腔布置,浇注系统的浇口采用潜伏浇口,推出形式为推杆推出机构完成塑件的推出;下壳以双分型面方式进行设计,模具型腔采取一模一腔,浇注系统的浇口采取点浇口,塑件有侧孔需要采用斜导柱滑块完成侧孔的横向分型,推出形式为推杆推出结构。由于塑件的工艺性能要求注塑模中有冷却系统,因此在模具设计中对模具整体结构进行了理论上分析,并对主要零部件作理论上受力分析与计算,确保塑料零件成型质量。10086

Inject mold Design of Camera Shell
Abstract: This graduation design is the design of injection mould for camera shell, camera housing is pided into the upper and the lower shell, plastic parts of the structure is more complex, as the case. On the basis of process performance and plastic product we identified: Design of shell with a single parting surface of injection mold way. The mould cavity using a mold 1 cavity layout, gating system using the side gate forming, roll out form pushing mechanism for putting the completion of the introduction of plastic parts; design the lower shell with double parting surface, cavity take a mold cavity, pouring system adopted point gate, plastics have side hole needs to adopt oblique guide pillar sliding finish side hole horizontal type, roll out in the form of putting out structure. Because the plastic parts of the process performance requirements of injection mold cooling system, so also in the mold design to design. The design of the reference to a lot of literature, is still on the Internet to find information, the design process is complete.
Key words: Injection mould;Submarine gate;pinpoint gate;oblique guide pillar; double parting surfaces
