This article conducts a feasibility analysis of the form elements of the handle skeleton, identifying the lateral grooves, lateral bosses, and arcuate high barriers present on its form. It also clarifies the elements such as grooves, holes, and cylinders that meet the requirements for mass production and appearance.For the lateral grooves, bosses,and the molding surfaces on both sides of the handle skeleton's parting surface I-I, as well as the arcuate high barriers at the front end, an oblique guide pin slider core-pulling mechanism is adopted. For other holes and grooves parallel to the mold opening and closing direction, an insert structure is used, and the mold opening and closing motion is utilized to complete the forming and core-pulling process. As long as the manufacturing accuracy of the joint surface between the injection mold parting surfaces I-I meets the standards, no mold structure marks will be left. The ejector pins are set at both ends of the handle skeleton, so after molding, any visible and hand-contactable parts will not show any mold structure marks. The mold adopts a one-shot two-cavity structure. The implementation of these measures not only ensures the smooth progress of the injection mold parting, core-pulling, and demolding movements but also guarantees that the shape and dimensions of the handle skeleton meet the drawing and appearance requirements.
