Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To prevent defective fixing and defective removal by a method in which after a molten resin being introduced into a cavity, out of a gate cutter and a center pin, only the gate cutter is actuated toward a gate. SOLUTION: After a molten resin being injected/packed into a cavity 10 between molds, a gate part 6 is cut with a gate cutter 8 installed at a position opposite to the part 6 protruded. In this process, a center pin 7 installed at the central part of the cutter 8 is not interlocked with the cutter 8. The cutter 8 protrudes from a retracted state, and the pin 7 is left at the position.
