To achieve the above object, the present utility model further provides a method for manufacturing a semiconductor device, comprising:

the die comprises a die body, wherein the lower surface of the die body is fixedly connected with a first fixing plate, the side surface of the die body is fixedly connected with a second fixing plate, the left surface of the die body is provided with a first groove, and the right surface of the die body is provided with a second groove;

the inner surface sliding connection of mould body has the heating cabinet, the upper surface of heating cabinet rotates and is connected with the handle.

According to the multi-purpose precoated sand mold, the first fixing plate and the second fixing plate are distributed left and right.

According to the multi-purpose precoated sand mold of a mold, the first bolt is connected with the internal thread of the first fixing plate, and the second bolt is connected with the internal thread of the second fixing plate.

According to the multi-purpose precoated sand mold, the size of the first groove is 0.8 times that of the second groove.

According to the multi-purpose precoated sand mold, a cavity is formed in the heating box, and a material injection port is formed in the upper surface of the heating box.

According to the multi-purpose precoated sand mold of a mold, the upper surface of the heating box is provided with a placing groove, and the shape of the placing groove is the same as that of the handle.

According to the multi-purpose precoated sand mold of the mold, the heating box is made of metal.

Additional aspects and advantages of the utility model will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the utility model.
