PROBLEM TO BE SOLVED : To certainly suppress the blister, deformation or crack of the resin produced by a reaction gas in the case of the insert molding of a component. ?SOLUTION : A resin molded product 1 is constituted by subjecting the components 3 to insert molding in resin parts 2A and 2B. Venting holes 5 reaching the surfaces of the components 3 are formed to the resin parts 2A and 2B so as to pierce the resin parts 2A and 2B. At the time of molding, the core pins 8 coming into contact with the surfaces of the components 3 are provided to a mold 6 and, after the mold 6 is filled with a resin, the core pins 8 are drawn out to perform venting. The resin is a thermosetting resin and the components 3 are, for example, rare earth metal magnets. ?COPYRIGHT : (C)2006, JPO&NCIPI ? |
