| Objective To solve the problems including poor quality of plastic bullet packing box molding and low production efficiency. Methods Field test and trials were conducted for the ejection mechanism of the box. By changing the prolapse and removal pressure parameters for the ejection mechanism of mould, the effect of unitary ejection mechanism on the box body quality. Using computer aided design and simulation analysis, based on the solid model originated from Pro /Engineer, the effects of multivariate joint ejection mechanism on the box body quality were simulated. Results The simulation results indicated the employment of multivariate joint ejection mechanism largely reduced the injection quality problems of plastic bullet packing box. Conclusion After improved from the unitary ejection mechanism into multivariate joint ejection mechanism, through production practice, the quality problems including ejection failure and deformation of box body parts were thoroughly solved, which greatly improved the production efficiency and achieved good comprehensive effects. |
