生产有倒陷式塑料制品是挑战塑料模具加工企业的一大难题。倒陷式注塑件是指在为了阻止注塑件沿着分模方向滑开,设计有突起或凹陷。这些结构阻止了模芯方向的移动,结果,通常必须使用到辅助模具部件,如滑动模芯或内部模芯伸缩机构,最终达到制品成形的目的。倒扣设计常常被用于生产旋装瓶盖等有螺纹制品和唇膏壳等扣合产品以及各种日用品 Production of inverted plastic products is a challenge plastic mold processing enterprises a major problem. Inverted injection molded parts are designed to prevent the injection molded parts from sliding along the parting direction, designed with protrusions or recesses. These structures prevent movement in the direction of the mold core. As a result, it is usually necessary to use auxiliary mold parts, such as a sliding mold core or an inner mold core retractable mechanism, for the ultimate purpose of product formation. Inverted design is often used to produce threaded products such as spin-on caps and lipstick shell and other fasteners and a variety of daily necessities
