に配設されている。(Example) In FIG. 1, 10 is a mold, which includes an upper mold 1 and a lower mold 2, which are made of metal molds. A casting cavity 3 having a predetermined shape is formed by the upper mold 1 and the lower mold 2. Then, each of these upper mold 1 and lower mold 2 has 10 Ils.
A cooling liquid flow path 4 having a diameter of about Φ is arranged so as to be located near the cavity 3.

Zn-An at a temperature of 550°C with circulating cooling water 7
! A molten metal 5 of the alloy is injected into the cavity 3 through a spout 6, and the molten metal 5 is rapidly cooled and solidified.

料が選ばれる。Note that the tensile strength and elongation of the Zn-Al alloy change depending on the temperature of the mold, as shown in Figure 2, so the temperature and circulation rate of the cooling water 7 should be such that the temperature of the molds 1 and 2 does not exceed 100°C. It is selected as follows. Further, the cooling liquid flow path 4 is arranged so that the inner surface of the cavity 3 has a substantially uniform temperature depending on the thickness, shape, etc. of the casting. Furthermore, the materials for the molds 1 and 2 are selected to have a melting point higher than 550° C. and a high thermal conductivity.
