Application of Moldflow software in design of injection mold

摘要

The filling process of plastic melts in the cavity of injection mold for the buckle in the automobile inner decoration was simulated based on the Moldflow software. The best gate location was obtained in this work, which ensures the product can be filled completely. Furthermore, the optimum design of gate location and number of plastic product were investigated. Based on the comparative analysis of gate, the single gate is superior to the double gate according to the distribution of air pocket and the weld line. In a word, the reasonable gate number and location ensure the injection mould work successfully, which decrease the manufacture cost.
