Abstract
This design on the analysis of the structure of lamp shade,and puts forward the mold design key points,designed the overall structure of the mold. According to the plastic pieces of parting surface,designed the push plate and the inclined plunger, the introduction of the structure,part uses the double parting surface point gate, improve the quality of the parts outside of the. Through to the plastic parts for process analysis and structure analysis,from the product structure craft,specific die structure, the mold of gating system,molding part of the structure,the ejection system, selection of injection machine and related parameters of checking all have detailed design. The mold one module and four cavities,adopts the thimble ejection structure. Through production verification,the die structure is reasonable,reliable operation.
