Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1, an aluminum alloy casting mold convenient for exhaust comprises a mold plate 1 and a fixed mold 3, the fixed mold 3 is fixedly connected to the center of the upper surface of the mold plate 1, positioning holes 2 are formed in the upper surface of the mold plate 1 near four corners, casting channels 4 are symmetrically formed in the upper surface of the mold plate 1, grooves 5 are formed in the surfaces of the casting channels 4, a plurality of ejector rod holes 6 are symmetrically formed in the surface of the fixed mold 3 along the center, ejector rods 7 are slidably connected to the inner portions of the ejector rod holes 6, a casting plate 8 is fixedly connected to the side wall of the mold plate 1, a pouring basin 9 is formed in the surface of the casting plate 8, and the pouring basin 9 is communicated with the casting channels 4.

Referring to fig. 1, a projection 10 is fixedly connected to the surface of the pouring basin 9 to guide the molten aluminum to smoothly enter the two pouring channels 4.

Referring to fig. 1, the bottom of the groove 5 is provided with a pin hole 13 for facilitating ejection of the product after molding.

Referring to fig. 1, the surface of the fixed mold 3 is symmetrically provided with thimble holes 11 along the center, so that the fixed mold 3 and the movable mold can be conveniently matched.

Referring to fig. 2, a plurality of mounting holes 12 are formed in the lower surface of the formwork 1, so that the formwork 1 can be conveniently mounted.

The working principle is as follows: after the mold is manufactured, pouring the aluminum alloy melted into the aluminum liquid into the mold, wherein the process of flowing the aluminum liquid into the mold is also the process of driving the gas in the mold forwards, in the process, the gas needs to be discharged out of the mold through a certain channel in time, otherwise, the aluminum liquid drives the gas to the last filling part, the front edge of the aluminum liquid generates air pressure due to the gas, the aluminum liquid is organized to fill the rearmost part on the mold, the rearmost part on the mold cannot be filled with the mold, casting defects can be generated, the contour of the cast is not clear if the cast is light, the contour of the cast is lost if the cast is heavy, scrapping is caused, therefore, ejector rods are designed at important parts of the cast, the air in the cast is discharged out of the mold in time, a plurality of special-shaped ejector rod holes 6 are arranged on the surface of the fixed mold 3, the perimeter of the special-shaped ejector rod holes 6 is larger than that of the circular ejector rod holes 6, and the gap between the ejector rods 7, in the casting process, the exhaust is carried out by the gap between the ejector rod 7 and the ejector rod hole 6 on the die body, so that the exhaust effect is good.
