[0003] However, when pouring a double-cylinder head of an air compressor as shown in Figure 1 and Figure 2 Since the surface of the double-cylinder head of the air compressor as product 9 is not allowed to have unevenness, but the pouring port of this mold pouring device faces the middle of the pouring box, and the pouring liquid enters the main cavity from the middle of the upper surface of product 9, which is easy to generate bubbles. And after product 9 is poured, a convex part will be formed on the upper surface of product 9, and the convex part needs to be polished to make the upper surface of product 9 flat, which affects production efficiency and production quality. Content of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a high-efficiency melting and casting mold for a double-cylinder head of an air compressor with lateral liquid inlet, and by arranging the sub-runners at the edge of the product, the purpose of improving production quality and production efficiency is achieved.

[0005] To solve the above technical problems, the technical solution of the utility model is: a high-efficiency melting and casting mold for a double-cylinder head of an air compressor with lateral liquid inlet, which includes an upper mold, a lower mold and an exhaust structure. The upper mold is provided with an upper cavity, the lower mold is provided with a lower cavity, the upper cavity and the lower cavity form a main cavity, the upper mold is provided with a pouring port, the exhaust structure is communicated with the main cavity, a main runner and a plurality of sub-runners are provided on the side of the upper mold facing the lower mold. One end of the main runner is communicated with the pouring port, one end of the plurality of sub-runners is communicated with the main runner, the other end of the sub-runners is communicated with the edge of the upper cavity, and the plurality of sub-runners are arranged along the length direction of the upper cavity.

[0006] To implement the above technical solution, the pouring liquid is injected into the main runner from the pouring port, then along the main runner into multiple sub-runners, and then along the sub-runners into the main cavity. Since the sub-runners are connected to the edge of the upper cavity, the pouring liquid enters the main cavity, and the gas is discharged from the exhaust structure. The travel of the pouring liquid is short, and few bubbles are generated. Moreover, after the product is formed, the convex part is located at the edge of the product, so only the convex part needs to be scraped off, eliminating the processes of grinding and polishing, so as to achieve the purpose of improving production efficiency and production quality.

[0007] As a preferred solution of the present utility model, it further includes an adjusting runner. The adjusting runner is located between two sub-runners.

[0011] As a preferred solution of the present utility model, there are multiple upper storage cavities, and the multiple upper storage cavities are evenly distributed along the length direction of the upper cavity.

[0012] To implement the above technical solution, a slag bag can be arranged in each upper storage cavity. Therefore, multiple slag bags can be formed to greatly improve the production quality of the product.

[0013] As a preferred solution of the utility model, the exhaust structure includes an upper exhaust block and a lower exhaust block, the upper exhaust block is connected to the upper mold, and the lower exhaust block is connected to the lower mold.

[0014] To implement the above technical solution, the air in the main cavity passes through the upper storage cavity, the lower storage cavity, the connecting groove, and the exhaust groove in sequence, and is finally discharged from the gap. A small amount of casting liquid enters the gap along with the air and is stored in the triangular groove. The gap presents a wavy shape, so as to pressurize the casting liquid and improve the production quality of the product.

[0015] As a preferred solution of the utility model, the distance of the gap gradually decreases in the direction away from the main cavity.

[0016] Implementing the above technical solution can enhance the effect of pressurizing the casting liquid, thereby improving the production quality of the product.
