Lifter system allows for deeper undercuts

TNP_DME_ac.gifMold designers are able to incorporate undercuts twice as deep as previously possible using D-M-E?s new VectorForm Lifter System, designed by Takao Injection Mold Engineering (Chiba, Japan). A slide base, as opposed to a static base, in the ejector plate allows the lifter angle to exceed the typical maximum angle of 15° to accommodate angles of 30° or more. The sliding base also makes it easy to accelerate the movement of the lifter core relative to the ejector plate. Unlike many pre-engineered lifter systems unable to handle large lifter cores, the VectorForm?s modular design allows ganging of multiple systems to handle larger cores. Multiple lifter cores can also be joined on a single lifter system, eliminating the need for a separate lifter system for each undercut where a part has multiple undercuts in the same line of draw. A guide rod support system permits extremely thin lifter cores with no flexing and easily incorporates cooling into the lifter core via the lifter rod. The VectorForm is available in six pre-engineered sizes for applications ranging from very large to very small.
