Aug 7, 2024 · Learn about the mold lifter in injection mold, from design principles to key components, enhancing part ejection and manufacturing efficiency. TL;DR: Mold lifters are essential components in injection molding that enable complex undercuts. Injection molding side actions are inserts (sometimes referred to as “features”) added to the mold in order to create undercut geometry. The design of these lifters directly impacts the overall success of the molding process, influencing factors like cycle time, part quality, and production efficiency. Give the lifter a push from the bottom up, which moves the lifter up for a certain distance to release the undercts. It is typically used in molds with geometries that prevent a straight pull from the mold cavity. While both are used to release undercuts and complex geometries, they differ in function, design, and application. Lifter is one of mechanisms of mold. In injection molds, rear mold lifter is a very common mechanism in injection molds, but if front mold part has undercuts, it is necessary to design a front mold lifter, so how should front mold lifter be designed?

This is a cut away of a basic lifter mechanism. So what is difference between slider and lifter? Basic principle of lifter and slider is to change vertical movement when mold is opened to horizontal movement. It works by moving perpendicular to the direction of the mold opening to free the molded part from the mold core or cavity. The choice of lifter mechanism depends on several factors, including the size and complexity of the part, the required force and speed of the lifter, and the available space in the mold. The injection molding lifter comprises two essential parts: the body and the shaping portions. The side core pulling mechanism of “fixed mold lifer+T-type lift guide block” is adopted for the fixed mold of bracket, and the side core pulling mechanism of “angle pin+slide” and These types of mechanisms include side-action slides, lifter rails, jiggler pins, collapsible cores and unscrewing mechanisms.
