Abstract
An apparatus for inserting preformed miniature precision metal stampings into a mold cavity for a subsequent plastic molding operation includes close tolerance positioning pins that accurately locate a die head assembly by fitting into respective holes in the mold base and pneumatic and electric motors for moving the die head vertically and horizontally, as well as forward and backward relative to the mold base. The metal stampings are preformed on a metal strip that is indexed in the insertion head by a pneumatically driven pilot pin and then pneumatic cylinders operate cutoff punches that detach the stampings from the strips and place them in the mold cavity. The entire insertion head assembly is permitted a small amount of movement necessary to align the positioning pins in the mold base holes by the provision of ball bearing mounting assemblies used to attach the insertion head apparatus to the base plate of the machine.
