Abstract
PURPOSE: To obtain a resin molded object which is light in weight and poor in internal stress, therefore, in molding distortion and in occurrence of shrinks by a method wherein its body is composed of a thin body and ribs, corners, bends, bosses, etc, are composed of thick bodies in which foamed parts are provided.
CONSTITUTION: The main body 41 of a resin molded object is composed of a thin body and ribs 42, corners, bends, bosses, etc. are composed of thick bodies in which foamed parts 43 are contained to obtain a desired resin molded object. In the constitution of molding dies for preparing a resin molded object, the space of the body part of such a resin molded object is prepared thinner than the ribs, the corners, the bends, the bosses. To take an example, after or the instant molten foaming resin is injected into a die, gas is forced into a die to make a hollow body once and after part of the surface layer of the hollow body is cured, the forced gas is discharged out of the die and the foaming resin is expanded in the hollow part to obtain the resin molded object.
