Process and mold for producing a multilayer molded article

Abstract

A multilayer molded article constitutes a resin body and a skin material which covers a part of the surface of the resin body so that an edge part of the skin material present on the surface of the resin body is placed in a groove formed on the surface of the resin body. The article is produced by providing an unclosed mold having a lower mold having at least one pin for fixing the edge part of the skin material at a position where the edge part of the skin material is placed and an upper mold having a kick for forming the groove, placing the skin material on the lower mold and fixing the edge part of the skin material with the pin, supplying a mass of resin melt between the skin material and the lower mold, and closing the upper and lower molds to form the multilayer molded article.

What is claimed is:  
     
         1 . A mold for producing a multilayer molded article comprising a resin body and a skin material which covers a part of the surface of the resin body and an edge part of which present on the surface of the resin mold is placed in a groove formed on the surface of the resin body, which mold comprises a lower mold having at least one pin for fixing the edge part of the skin material at a position where the edge part of the skin material is placed and an upper mold having a kick for forming the groove on the surface of the resin body.  
     
     
         2 . The mold according to  claim 1 , wherein the fixing pin is retained on a protrusion on the lower mold.  
     
     
         3 . The mold according to  claim 2  , wherein the protrusions are movable in a direction in which the upper and lower molds are closed.  
     
     
         4 . The mold according to  claim 2 , wherein the pins are formed in a groove which is formed in the lower mold.
