Claims

[Scope of utility model registration request]

A pair of gate-receiving bodies each having a gate-receiving groove for receiving the gate of a runner of a molded product made of soft resin and movable in opposite directions; A rotating shaft to which threaded portions in opposite directions are respectively screwed together, a rotational drive unit that rotationally drives the rotating shaft, a fixed blade attached to one edge of the gate receiving groove, and a rotating shaft that rotates the rotating shaft, and a fixed blade attached to one edge of the gate receiving groove. a movable blade attached movably to the fixed blade side on the other edge;
A cam is provided on the rotating shaft and moves the movable blade toward the fixed blade when the rotating shaft rotates, and after the gate portion of the runner is received in both gate receiving grooves, the rotating shaft is moved. The soft resin is characterized in that when rotated, both the gate portion receivers move in a direction to separate from each other, and the movable blade is moved toward the fixed blade side by the cam to cut the gate portion of the runner. gate cutting machine.
