[0017] Beneficial effects of the present invention: 1. The present invention can prepare the metal material into semi-solid metal slurry by setting a slurry making mechanism. The metal particles enter the inner cavity of the melting tank through the feeding component. The heater heats the metal material inside the melting tank to melt it into liquid metal. During the melting process, the output shaft of the second reduction motor drives the stirring component to rotate. The stirring component stirs the metal material to increase its melting efficiency. After the melting is completed, the third cylinder is started. The third cylinder drives the blocking rod to move upward to separate the blocking rod from the discharge hole on the annular plate. The liquid metal enters the inner cavity of the molding tank through the annular plate for cooling. The external cooling water circulates inside the coolant pipe to cool the liquid metal inside the molding tank. The heat is absorbed to cool it down to form a semi-solid metal slurry. When melting the metal and preparing the metal slurry, the external inert gas enters the one-way air outlet nozzle through the air intake control component and the delivery pipe, and is sprayed into the inner cavity of the melting tank and the molding tank through the one-way air outlet nozzle to prevent the metal liquid from oxidation, and is injected into the metal liquid to form metal particles in the metal liquid.

The controller controls the temperature of the heater and the cooling water according to the detection data, and controls the heating and cooling temperatures. The semi-solid metal slurry finally formed enters the discharge valve through the bottom of the molding tank.

[0018] 2. The present invention can facilitate die-casting of semi-solid metal slurry to form metal parts through the coordinated use of the first die-casting mechanism and the second die-casting mechanism. The metal slurry inside the discharge valve enters the cylinder through the pipeline, and the output shaft of the first reduction motor drives the screw rod to rotate, and the screw rod transports the metal slurry to the inside of the fixed mold and the movable mold.

[0019] 3. The present invention is provided with a release agent spraying mechanism, which can facilitate the spraying of the release agent on the inside of the movable mold and the fixed mold, facilitate the rapid demoulding of the metal parts, and prevent the deformation and damage of the metal parts. The output shaft of the stepper motor drives the connecting pipe to rotate, and the connecting pipe drives the first spraying pipe and the flip frame to rotate, so that the first spraying pipe and the second spraying pipe move to the top of the movable mold, and the liquid pump extracts the release agent inside the mixing barrel through the liquid extraction pipe and the filter cylinder, and the filter cylinder prevents impurities in the release agent from entering the liquid pump. The release agent extracted by the liquid pump is transported to the first spraying pipe through the second hose and the connecting pipe, and the release agent inside the first spraying pipe enters the second spraying pipe through the first hose, and is finally sprayed on the inner cavity of the movable mold through a plurality of nozzles. When it is necessary to spray the fixed mold, the output shaft of the motor drives the pinion to rotate, and the pinion drives the first spraying pipe to rotate ninety degrees. The rotation of the first spraying pipe drives the rotating The ring rotates inside the limiting shell to keep the first spray pipe and the connecting pipe connected. When the nozzle rotates to the bottom of the fixed mold, the release agent is sprayed on the inner cavity of the fixed mold to achieve efficient spraying. After the spraying is completed, the release agent spraying mechanism is reset for subsequent die-casting. When it is necessary to adjust the spraying range, the fourth cylinder is started, and the fourth cylinder drives the second spray pipe to slide inside the arc-shaped slide groove on the turning frame to adjust the position of the nozzles on the front and rear sides. By adjusting the spraying range, it can be suitable for molds of different sizes. The mixing barrel stores the release agent, and the release agent can be added to the mixing barrel through the liquid inlet hopper. The output shaft of the driving motor drives the turntable to rotate, and the turntable drives the filter drum and the stirring rack to rotate synchronously. The stirring rack stirs the release agent inside the mixing barrel to prevent the release agent from precipitating. The filter drum rotates to clean the impurities on its surface to prevent the filter drum from being blocked and affecting the liquid inlet of the liquid extraction tube.
