Abstract

PURPOSE: To dispense with the cut-off operation of a molded piece in an after process so as to improve an injection mold device of this design in productivity, to save labor, to lessen the molded piece in cost, and to improve it in product quality by a method wherein a cut-off operation is executed in such a manner that the molded piece and a runner section are cut off from each other at a gate.
CONSTITUTION: Liquid resin is filled into a molding recess 28 through the intermediary of a sprue 21, a runner 22, and a thinned gate 35, which is cooled down and solidified to form a molded piece 40 in the molding recess 28. When a second parting is opened, a runner piece 9 fixed to a support plate 2 is made to recede and a runner section 42 connected to the molded piece 40 is pushed by a sprue-ejector pin 13, whereby a gate section which connects the runner section 42 with the molded piece 40 is cut off to separate the molded piece 40 from the runner section 42. Then, when a first parting starts opening, a runner ejector plate 8 is pushed by a spring 19 to move forward and the runner section 42 is cut off by a runner ejector pin 16.
