[0018] Compared with the prior art, the beneficial effects of the present utility model are: the squeeze casting machine for producing bicycle hook claws that is convenient for ladling in the injection chamber:

[0019] 1. The pressurizing mechanism solves the problem of injecting molten metal into the molten metal storage tank. Before casting the bicycle claw, one end of the pressurized air pipe of the pressure pump is threadedly connected to the joint. When liquid injection is required, the pressure pump is started. The pressure pump injects compressed gas into the joint. The piston in the joint moves downward under pressure. When the lower end of the piston reaches the upper surface of the bottom plate, the piston stops moving and blocks the opening on the side surface of the joint. The compressed gas is injected into the molten metal storage tank through the opening on the side surface of the piston. Under the action of the high-pressure compressed gas, the molten metal in the molten metal storage tank flows from the liquid injection pipe to the liquid injection port and is injected into the push pipe through the liquid injection port. Under the action of the push pipe, the molten metal is pushed into the injection chamber body, thus completing the pouring process. The hydraulic rod on the support frame is started to provide pressure for the shaping of the molten metal. Compared with the traditional robotic arm transportation method, this mechanism is safer. The staff will not come into contact with the high-temperature molten metal, and the liquid injection speed is faster. After the liquid injection is completed, the pressure pump is stopped. Without the action of the applied pressure, the piston is pulled back to the initial position by the tension spring. The gas in the molten metal storage tank flows out through the opening on the side surface of the joint. The molten metal that has lost the pressurizing effect falls back in the liquid injection pipe and flows back into the molten metal storage tank, preventing the metal from condensing in the liquid injection pipe and preventing the gas pressure in the molten metal storage tank from being too high and causing an explosion under long-term high temperature.

[0020] 2. The cooling mechanism solves the problem of rapid cooling of the circulating water. Under the action of the circulating pump, water flows in the circulating pipe. When the water passes through the annular water tank, it takes away the heat of the high-temperature molten metal in the mold on one side of the casting machine body, thus accelerating the shaping of the molten metal. During the flow of the water, it drives the water runner in the water wheel housing to rotate. The first meshing gear on one side of the water runner shaft drives the second meshing gear to rotate at the same time. The fan at one end of the second meshing gear rotates at the same time. During the rotation of the fan, the heat dissipation effect of the heat sink is increased, ensuring that the water in the transfer water tank can be quickly cooled. Description of the Drawings
