る。However, 1, the temperature rise by the electric heating coil takes time and is not efficient. 2. In the case of a drawing mold or a ceramic mold, lubricating oil must be used (applied) in order to prevent defects such as galling and breakage at corners. 3. Because of the warm working, the lubricating oil is seized and blackened on the processed product. This must be removed later. 4. Distortion occurs in the flat part of the drawn product, which must be corrected later. 5. The ceramic mold in which the high-frequency inductor coil is set is mainly for molding a glass material. The present invention has been made to solve the above drawbacks.

る。The punch and die are made of graphite, drawn and formed without using a lubricating oil, and a high-frequency inductor coil is set inside (inside) the mold. The temperature of the magnesium alloy or the like is raised to the superplastic working zone temperature. Cooling water is flowed through the lower retainer, and after molding, the lower retainer is cooled in a pressed state to prevent distortion.

Graphite is used for the molding material. As shown in FIG. 1, the magnesium alloy plate 3 to be drawn is placed on the die 2 and, at the same time, the high-frequency inductor coil 4 is energized and heated to a superplastic working region temperature of about 300 to 400 ° C. Then, as shown in FIG. 2, the punch 1 is pressed into the die 2 side,
Draw. Cooling water is supplied to the cooling water passage 6 while the flat part is pressed by the lower retainer 5 to cool the molded product. Release the pressure and take out the product.

発生が少ない。 ３，高周波誘導加熱のため、短時間で昇温できる。 ４，下押さえ状態で冷却するので、平坦部の歪みの発生
が押さえられる。According to the present invention, the following effects can be obtained. 1. Since graphite is used for the mold, the thermal expansion of the mold due to heating is extremely small. 2. Even if lubricating oil is not used, generation of defects such as galling and breakage is small. 3. Due to high frequency induction heating, the temperature can be raised in a short time. 4. Since the cooling is performed in the lower holding state, the generation of the distortion of the flat portion is suppressed.
