SLIDE DRIVING STRUCTURE OF INJECTION MOLDING DIE

摘要

A slide driving structure for undercut of an injection molding die is provided to drive a slide with a time interval from separation of a main core without using a separate driving source, and to drive the slide by separation motion of the main core. A slide driving structure for undercut of an injection molding die includes: a first disc plate(32) provided at the first fixing plate(30) mounted on one side of a molding device; a first main core(34) provided at the first disc plate; a second disc plate(56) provided at the second fixing plate(50) mounted on the other side of the molding device; a second main core(58) provided at the second disc plate; a slide(62) forming a cavity corresponding to the shape of a product by cooperating with the first and second main cores; and a two-stage angular pin(44) including a waiting unit(46) and a driving unit(47), and moving the slide by separating and approaching motion of the first and second main cores.
