A die spring that supports the die pushed during product molding and is formed in contact with one side of the die inside the die holder so that the die returns to the initial position after molding is completed, and the other side is in contact with one side of the fixed pin holder;
The floating pin holder counteracts the tension of the die spring to return the molded blank to its initial position, while the floating pin holder flows inside the fixed pin holder. When the blank is discharged, the ejector pin pushes the die sleeve plate to the die sleeve When pushing the blank, it is made of a KO (knock out) middle pin that prevents it from returning due to spring elasticity so that the transfer clamp can move the blank smoothly.
