Title:
METHOD AND MOLD FOR PRODUCING FIBER REINFORCED THERMOPLASTIC RESIN MOLDING
Document Type and Number:
Japanese Patent JPH081698
Kind Code:
A
Abstract:

PURPOSE: To produce a fiber reinforced thermoplastic resin molding excellent in surface appearance having a,protruding shape such as a rib or a boss by one molding processing.

CONSTITUTION: A fiber reinforced thermoplastic resin sheet 8 heated to the melting temp. of a resin or higher is placed on the cavity surface of a lower mold and, after mold clamping and cooling, upper and lower molds are opened to produce a fiber reinforced thermoplastic resin molded article. In this method, a lower mold having a plurality of up and down slidable holding pins 5 therein is used and the pins 5 are allowed to protrude into a cavity from the surface of the lower mold and, thereafter, the heated fiber reinforced thermoplastic resin sheet 8 is placed on the pins 5 so as not to come into contact with the cavity surface. Subsequently, the holding pins 5 are received in the lower mold immediately before the cavity surface of the upper mold comes into contact with the sheet while the molds are closed and mold clamping is performed until a clearance becomes the thickness of a final product and, after cooling, the molding is taken out.
