Patent ID: 7018190

Claim:
A resin multilayer molding device in which a skin material having a resin decorating layer on a surface and a core-material resin are integrally molded in a mold, comprising: carrying means for carrying and setting the skin material to a predetermined position of a mold cavity and carrying a molded product to a predetermined position after molding, and supply means for supplying a molten resin forming a core material into a mold cavity space; and a clamping condition setting section for setting/entering a clamping condition and a thickness of an air insulating layer during supply and after supply of the molten resin, a change-overtiming setting section for a change-overtiming condition for forming the air insulating layer, a temperature detecting section for detecting a temperature of the core-material resin and a temperature of the resin decorating layer of the skin material during molding, a comparison control section for comparing/determining a detection signal of the temperature detecting section and a set value of the change-over timing setting section, and a clamping control section for controlling clamping means based on a signal of the comparison control section and a set value of the clamping condition setting section.
