PROBLEM TO BE SOLVED: To provide a cassette type resin molding mold in which a mold frame on the cavity side and a mold frame on the core side in a mold base are mated with each other without forming an excess void and without needing a wedge member, the number of components is reduced, the structure is simplified, a resin is molded well, and the efficiency of work is improved.;SOLUTION: In the cassette type resin molding mold, a set of mold frames 6 and 7 on the core side and on the cavity side produced corresponding to the shape of a resin molding H are replaceably fitted to the facing charged window parts 2a and 3a of separable mold bases 2 and 3 with attachment channels 2b and 3b corresponding to them formed. The mold frame 7 on the core side and the mold frame 6 on the cavity side are formed from a metal material having a higher thermal expansion coefficient than that of the mold bases 2 and 3.;COPYRIGHT: (C)2004,JPO
