A lower slide bar 20 is vertically connected to the lower right end of the movable rod 18, and a movable rack 21 is vertically provided on the right end of the lower slide bar 20. The movable rack 21 is meshed and connected with the top movable end of the lifting rod 22 through the latch tooth. After the die-casting is completed, the movable rod 18 moves to the left, driving the sliding rod 20 to move to the left, so that the movable rack 21 connected thereto starts to move. When the movable rack 21 moves to the left, it drives the movable end of the lifting rod 22 meshing therewith to start to rotate. When the movable end of the lifting rod 22 rotates, it moves upward along the fixed end threadedly connected thereto, so that the blanking plate moves upward along the guide bar 39 until the blanking plate passes through the blanking port 37 and moves to the bottom of the fixed mold 10. At this time, the workpiece is taken out by the clamp 50 and falls on the surface of the blanking plate under the action of gravity. When the movable rack 21 moves to the right again, the lifting rod 22 shortens, driving the blanking plate and the workpiece to move to the bottom of the inner groove. When the blanking plate moves to the bottom of the top plate 38, the electric telescopic rod extends to remove the workpiece on the surface of the blanking plate. Through the above steps, automatic unloading of the workpiece can be achieved, and damage to the workpiece caused by excessive height when the workpiece falls can be avoided.

[0030] A driving bevel gear 14 is arranged around the outer edge of the rotating disk 13, and a driven bevel gear 15 is meshed on the left side of the driving bevel gear 14. A rotating shaft is connected to the left center of the driven bevel gear 15. A heat dissipation hole is opened on the upper left side of the main body 1, and the left end of the rotating shaft extends to the inside of the heat dissipation hole. A plurality of blades 16 are arranged on the left end side wall of the rotating shaft. A driving wheel is arranged at the center of the rear side wall of the rotating disk 13, and transmission rollers 23 are arranged on both sides of the bottom of the inner groove. A driven wheel 24 is arranged at the center of the transmission roller 23 on the left side. A transmission chain 25 is arranged on the meshing sleeve between the driving wheel and the driven wheel 24, and a conveyor belt is arranged on the meshing sleeve between the transmission rollers 23. The conveyor belt is located below the top plate 38. After the workpiece is pushed out of the unloading plate, it falls on the surface of the conveyor belt. When the rotating disk 13 rotates, it drives the driving wheel to start rotating. When the driving wheel rotates, it drives the driven wheel 24 to start rotating through the transmission chain 25 meshing with it. When the driven wheel 24 rotates, it drives the transmission roller 23 to start rotating, so that the conveyor belt meshing with it starts to move, and the workpiece on the surface of the conveyor belt is transported to the outside of the main body 1. When the rotating disk 13 rotates, it drives the driving bevel gear 14 on its outer edge to start rotating, so that the driven bevel gear 15 meshing with it starts to rotate. When the driven bevel gear 15 rotates, it drives the rotating shaft to start rotating, so that the blades 16 inside the heat dissipation hole start rotating, generating wind force to cool the workpiece, thereby realizing automatic cooling of the workpiece during transportation, which is convenient for the next step of processing of the workpiece. Working principle: During die-casting, the driving motor drives the rotating disk 13 to start rotating, so that the rotating rod 17 connected to the edge of the rotating disk 13 rotates accordingly, and when the rotating rod 17 rotates, it drives the movable rod 18 to move left and right periodically in the horizontal direction. When the movable rod 18 moves to the right, it drives the top slider to move to the right, so that the movable bar moves to the right along the guide rod 8. When the movable table 6 moves to the right, it drives the connecting rod 11 and the movable mold 9 to move to the right until the movable mold 9 abuts against the fixed mold 10. At this time, the movable mold 9 continues to move to the right, so that relative movement occurs between the connecting rod 11 and the outer ring 41. The first spring 40 is compressed to generate a thrust on the movable mold 9, so that the movable mold 9 and the fixed mold 10 always keep a close fit. When the connecting rod 11 moves, it drives the driving rack 42 to move toward the direction of the fixed mold 10 until the driving rack 42 penetrates into the interior of the slot 43. When the driving rack 42 moves to the deepest part of the inner slot When the trigger button 44 is pressed, the trigger button 44 is squeezed. At this time, the thrust on the movable mold 9 is the largest. When the trigger button 44 is squeezed, the electric hydraulic rod 31 is extended, driving the piston 34 at its bottom to move toward the bottom of the hydraulic chamber 33, generating high pressure on the metal solution inside the hydraulic chamber 33, so that the metal solution is sprayed out along the liquid outlet 36, and then flows into the infusion hole 28 through the liquid inlet pipe 29, and finally sprayed into the inside of the die-casting groove 26 along the spray hole 27 to perform a die-casting operation on the workpiece. After the die-casting is completed, the movable mold 9 moves in the opposite direction. At this time, the driving rack 42 is disengaged from the trigger button 44, so that the electric hydraulic rod 31 is reset, driving the piston 34 to move upward, and negative pressure is generated inside the hydraulic chamber 33. When the piston 34 moves to the top of the liquid inlet 35, the metal solution inside the inner liquid tank 32 is poured into the inside of the hydraulic chamber 33 again under the action of negative pressure. Through the above steps, continuous and automatic filling of the metal solution can be achieved, effectively improving the die-casting efficiency.

[0031] When the driving rack 42 moves to the right, it drives the transmission gear 45 meshing with it to start rotating, so that the driven rack 46 meshing with the other side of the transmission gear 45 moves in the opposite direction. When the transmission rack moves, it drives the connecting rod to move accordingly. When the connecting rod moves, it drives the limit rod 47 to move accordingly, so that the limit rod 47 is stuck in the inside of the limit groove during die-casting, thereby reducing the vibration between the movable mold 9 and the fixed mold 10 during die-casting, avoiding deformation of the workpiece during die-casting, and improving the die-casting quality; by providing a sealing groove 48, the sealing performance of the movable mold 9 and the fixed mold 10 during die-casting can be improved to avoid overflow of the molten metal under high pressure.

[0032] When the movable table 6 moves to the right, it drives the top rod 12 to move to the right. When the top rod 12 moves, it drives the installation rod 49 to move accordingly. When the installation rod 49 moves, it drives the clamping jaws 50 on both sides of the bottom to move accordingly. When the clamping jaws 50 move and contact with the wedge-shaped top block 53, they are pushed outward, so that the clamping jaws 50 are separated during die-casting, and the second spring 51 is extended to generate a pulling force in the opposite direction. When the die-casting is completed, the installation rod 49 is reset. At this time, the clamping jaws 50 are closed under the pulling force of the second spring 51, driving the clamping block 52 to move toward the workpiece formed inside the die-casting groove 26, and the workpiece is taken out. After the die-casting is completed, the movable rod 18 moves to the left, driving the sliding rod 20 to move to the left, so that the movable rack 21 connected thereto starts to move, and the movable rack 21 moves to When it moves to the left, the movable end of the lifting rod 22 engaged with it starts to rotate. When the movable end of the lifting rod 22 rotates, it moves upward along the fixed end threadedly connected to it, so that the blanking plate moves upward along the guide bar 39 until the blanking plate passes through the blanking port 37 and moves to the bottom of the fixed mold 10. At this time, the workpiece is taken out by the clamp 50 and falls on the surface of the blanking plate under the action of gravity. When the movable rack 21 moves to the right again, the lifting rod 22 shortens, driving the blanking plate and the workpiece to move to the bottom of the inner groove. When the blanking plate moves to the bottom of the top plate 38, the electric telescopic rod extends to remove the workpiece on the surface of the blanking plate. Through the above steps, automatic unloading of the workpiece can be achieved, and damage to the workpiece caused by excessive height when the workpiece falls can be avoided.

[0033] After the workpiece is pushed out of the unloading plate, it falls on the surface of the conveyor belt. When the rotating disk 13 rotates, it drives the driving wheel to start rotating. When the driving wheel rotates, it drives the driven wheel 24 to start rotating through the transmission chain 25 meshing with it. When the driven wheel 24 rotates, it drives the transmission roller 23 to start rotating, so that the conveyor belt meshing with it starts to move, and the workpiece on the surface of the conveyor belt is transported to the outside of the main body 1. When the rotating disk 13 rotates, it drives the driving bevel gear 14 on its outer edge to start rotating, so that the driven bevel gear 15 meshing with it starts to rotate. When the driven bevel gear 15 rotates, it drives the rotating shaft to start rotating, so that the blades 16 inside the heat dissipation hole start rotating, generating wind force to cool the workpiece, thereby realizing automatic cooling of the workpiece during transportation, which is convenient for the next step of processing of the workpiece.
