ABSTRACT:
A compression forming apparatus for forming a thermoplastic resin sheet is disclosed wherein a thermoplastic resin blank is compressed between a pair of heated mold plates, the mold plates are cooled to solidify the thus-formed sheet, and the sheet is taken out from the mold plates. This compression forming apparatus has a clamping device, a pair of cooling die plates, a pair of mold plates which are attached to the cooling die plates, means for heating the mold plates, and springs or actuators enabling the mold plates to be held in contact with the cooling die plates when the mold plates are clamped and held in non-contact with the cooling die plates when the mold plates are opened.
