Abstract: PROBLEM TO BE SOLVED: To lessen the quantity of resin remaining in a runner, a cull, etc., after resin molding and to improve the efficiency of use of resin, in a mold for sealing with the resin which is made up of a cavity, the runner, the cull and a pot. SOLUTION: Granular or powdery resin being used, a square pot 5 is formed in a part of a runner 4 formed in one mold 2 of upper and lower molds 1 and 2 forming a cavity 3 and a plunger 6 is disposed therein. In the other mold 1, a portion corresponding to the square pot 5 is made flat and no cull is formed therein. Since filling of resin in the cavity 3 is enabled by using the runner 4 and the square pot 5, the resin can be prevented from remaining in the cull after resin molding and the quantity of wasteful resin can be lessened. By adopting a multi-plunger system, besides, the length of the runner is made short and reduction of the quantity of resin remaining in the runner is also enabled.  Moreover, location of the cavity hardly produces an effect, the tendency of the state of hardening of the resin in each cavity to be uneven is also eliminated and thus an improvement in the reliability of products can be expected.
