Abstract

PURPOSE: To avoid thinning and to reduce molding cycle while the thermoplastic synthetic resin sheet is machined by stamping in the solid state, by cooling the part corresponding to the thin part of the molded product and then performing machining.
CONSTITUTION: A cooling pad 13, whose temperature is adjusted to a specified temperature immediately before stamping molding, is pressed to a part of a shoulder of a mold which contacts a blank 6 at first for a specified time period in stamping molding. Said part of the blank 6 is cooled to increase its tension i.e. elastic modulus to the large extent and to yield the same effect as that yielded in the machining hardening of a metal sheet. Thus the thinning is avoided and the drawing performance is improved. After the cooling, the blank 6 is placed on a blank holder 5 and protruded from a male mold 4. Molding is performed with a wrinkle-suppressing force being applied between the blank holder 5 and a peripheral part 16 of an upper mold.
