PROBLEM TO BE SOLVED: To realize resin mold by surely attractingly support a molding to a projecting insert by a method wherein an attractingly supporting means for attractingly supporting a molding made of magnetic body material by means of magnetic force to the projecting insert installed on a resin molding die. SOLUTION: This resin mold assembly is composed of molding dies 30a and 30b, in which a pot 10 communicating with a plurality of cavity recesses provided on a molding surface is opened parallel to the direction of arrangement of the cavity recesses from one end side cavity recesses to the other end side cavity recesses. In this case, a plunger to be installed in the pot 10 is composed of a combination plunger divided in a plurality of plungers 18a, 18b and 18c in the longitudinal direction of the pot 10. The divided combination plungers are respectively and independently connected with the driving mechanisms 34a, 34b and 34c of the plungers. |
