Abstract

PURPOSE: To trim the molded article smoothly and uniformly, to unnecessitate the finishing of cut faces, to reduce the pressure applied to a supporting die and to construct the supporting die economically by a method wherein a cutting edge maintained at a predetermined temperature by a controlled heating is pressed against the part to be cut of the molded article for a predetermined period of time.
CONSTITUTION: A heating plate incorporating a heater 5a is coupled by a pin to a connecting plate 3 of a pneumatic cylinder 1, and the objective part 7a of the molded article 7 supported by the supporting die 8 is cut by the cutting edge 6 fixed to the heating plate 5. The heater 5a and the pressure of the cylinder 1 are controlled according to the wall thickness of the objective part 7a. After the cutting is completed, the cutting edge 6 is pressed against the objective part 7a while maintaining the pressure of the cylinder 1 at a preset value for the period of time set by a timer.
