したことである。(Step F to solve the problem) The L step to solve the problem below consists of a female mold, a male mold, and a blank holder. It is divided into a !7 m part and other general-purpose parts, and the dedicated part is used to mold a mold from the product model and inject low-melting point materials such as low-melting point metals and synthetic resins into the mold. A process of filling and manufacturing a male mold part, fixing the male mold part to the general-purpose part of the mold part, pasting a heat-resistant sheet on the surface of the mold part so that it has the same thickness as the product to be molded, Next, a blank holster and a mackerel type 7Jt part are combined on this hill to form a space in which the male mold part is molded between the male mold part surface and the female general purpose part, and a low mold part is formed in the space in the same manner as above. The male mold part and the corresponding female mold part are molded by injecting and filling the melting point material.
