Abstract

Shown above is an enlargement of the gate area in a plastic injection molding press. Probe 10 inside the head of the injection press is designed to provide a space of 0.006 inch (.15 mm) in space 12 between the front tip of probe 10 and the side wall 14 of the part mold. Gate 18 through the mold wall to mold cavity 16 is adjacent the front tip of probe 10. By providing the 0.006 inch (.15 mm) gap 12 between the mold wall 14 and the front tip of the probe, heat flow from probe 10 to the mold and the molded part is reduced. This facilitates breaking off sprue at gate 18 when injection is complete and the molded part moves out from the mold in the direction of arrow 20.
