Abstract
Plastic industry is in the world grows now one of quickest industry classes, but casts the mold is development quick type, therefore, the research casts the mold to understand the plastic product the production process and improves the product quality to have the very big significance.One injection mold for a type of vacuum cleaner’s covere was designed in this dissertation. Firstly, the author chose a single parting surface for the mould according to the analysis of the plastic part craft, and finished mold parts modeling with the UG Moldwizard such as the modeling of ejection parts, guide parts ,and other structure parts and so on. And has carried on each parameter effect nucleus. Finally. the assembly drawing and some of the important parts drawings were made in the AutoCad. As a whole the mould is simple in structure and good at working reliability. The design of this injection mold is of some significance for the fact production..
