Abstract

PURPOSE:To perform sharp gate cutting, by using the cutter provided to the pedestal and the side face of the pedestal to cut off from the runner the synthetic resin product integrated with the runner. CONSTITUTION:Positioning of the gate is at first conducted, while the runner B is placed in the groove 8 on the surface of the pedestal 2, in order to cut off the product A from the runner B. Then, the ram 7 is pushed out by delivering air in the air cylinder, the cutter 9 is moved sidewards, until the blade edge of the cutter 9 coincides with the gate. When positioning is finished, the cutter 9 is sustained by fastening the screw 12, the position of the ram 7 is left as it is. After positioning, when the runner B is placed in the groove 8 of the pedestal 2 and the pedestal 2 is pushed in, the blade edge of the cutter 9 is brought in contact with the gate of the product A and cutting is performed.
