Abstract
Plastic injection molding apparatus consisting of two mold sections which define a mold cavity therebetween and are relatively movable to permit formation and removal of an article through the injection of hot melted plastic under high pressure. A plurality of coring pins are employed in conjunction with the mold sections to create voids of desired configuration in the molded article. Means are included to sense the pressure of the hot melted plastic as it enters the apparatus, and to actuate the coring pins into position within the mold cavity to create the desired voids. The coring pins also sense pressure within the mold cavity to achieve a balanced, self-adjusting operation.
