[0002] Forging dies are dies used in the forging process, mainly used to process metal materials into forgings of various shapes and sizes. Forging dies usually consist of an upper die and a lower die. The upper die is installed on a press and the lower die is installed on a workbench. The shape of the die cavity is the same as the shape of the forging so that the metal material can be formed. Forging dies need to have properties such as high strength, high hardness, wear resistance and heat resistance. Commonly used die materials include tool steel, high-speed steel, cemented carbide, etc.

[0003] The existing forging molds for aluminum alloy transmission cases have certain shortcomings. When the upper and lower molds are closed, molten aluminum alloy liquid is injected into the mold through a feed pipe and then solidified. The aluminum alloy in the feed pipe will also solidify, so that the mold needs to be cut twice after processing, and the excess part is cut off and then polished, which increases the processing steps of the aluminum alloy transmission case, reduces production efficiency, and easily causes material waste.

The aluminum alloy transmission box is forged between the tool 1 and the liquid inlet component 2. The excess liquid is discharged from the drain pipe 205 through the setting of the first closing mechanism 203 and the second closing mechanism 204 to avoid waste of excess liquid. One end of the infusion tube 202 is fixedly connected to the top of one end of the lower mold 1 to ensure that the liquid input by the infusion tube 202 can fill the interior of the lower mold 1 to ensure the forging effect. The size of the liquid inlet 201 is larger than the size of the infusion tube 202 to ensure that the aluminum alloy liquid can be better poured into the infusion tube 202.

[0025] The first closing mechanism 203 includes a mounting frame 210, a cylinder 211, a lifting rod 212 and a closing door 213. The mounting frame 210 is fixedly connected to the top of the infusion tube 202, the cylinder 211 is fixedly connected to the top of the mounting frame 210, the lifting rod 212 is pneumatically lifted and connected to the bottom of the cylinder 211, and the closing door 213 is fixedly connected to the bottom of the lifting rod 212.
