Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub casting molds, in particular to a water-cooling mold for automobile wheel hub casting. Background Art

[0002] Automobile wheel casting involves heating solid metal (primarily aluminum) into a liquid state, injecting it into a specific mold, and then cooling and solidifying it into the shape of the automobile wheel. A water-cooled mold is a mold used to manufacture molded products made of materials such as plastic and rubber. It has an internal cooling water system to eliminate heat generated during the molding process. Water-cooled molds are suitable for workplaces requiring high-precision molding and mass production. Wheel casting generally requires a water-cooled mold for manufacturing, such as a water-cooled mold for automobile wheel casting.

[0003] The water-cooled molds for wheel hub casting currently on the market are generally composed of an upper mold body, a lower mold body and a side mold. Water-cooling channels are opened in the inner cavities of the upper mold body and the lower mold body to cool the product, so that the liquid aluminum is injected into the mold and then cooled and formed to form a finished product. However, after the superheated liquid aluminum enters the water-cooling channel, although the cooling speed is faster, the mold body is still hot after heat conduction, and air cooling cannot be used simultaneously to speed up the heat dissipation speed. Therefore, a water-cooling mold for automobile wheel hub casting is proposed, which can be equipped with water-cooling channels and air-cooling channels on the side mold to achieve double cooling and speed up the cooling speed of the product. Summary of the Invention

It solves the problem that after the superheated liquid aluminum enters the water-cooling channel, although the cooling speed is faster, the mold body is still hot after heat conduction, and air cooling cannot be used simultaneously.

[0005] In order to achieve the above-mentioned purpose of being able to set water cooling channels and air cooling channels on the side molds to double the cooling speed and accelerate the cooling speed of the product, the utility model provides the following technical solutions: a water-cooled mold for casting an automobile wheel hub, comprising an upper mold body and a lower mold body, a left mold and a right mold are arranged on the top of the lower mold body, and a cooling mechanism is arranged inside the right mold;
