The workpiece is pushed out of the blanking plate and falls on the surface of the conveying belt. When the rotating disc 13 rotates, the driving wheel starts to rotate, the driving wheel rotates and drives the driven wheel 24 to start rotating through the transmission chain 25 engaged with the driving wheel, the driven wheel 24 rotates and drives the transmission roller 23 to start rotating, so that the conveying belt engaged with the transmission roller 23 starts to move, the workpiece on the surface of the conveying belt is conveyed to the outside of the main body 1, the rotating disc 13 rotates and drives the driving bevel gear 14 on the outer edge to start rotating, so that the driven bevel gear 15 engaged with the driving bevel gear 14 starts to rotate, the driven bevel gear 15 rotates and drives the rotating shaft to start rotating, so that the blades 16 in the heat dissipation hole start to rotate, wind power is generated, the workpiece is cooled, so that automatic cooling during conveying of the workpiece is realized, and the workpiece is convenient for next step processing.

[0032] Working principle: when die casting, the driving motor drives the rotating disc 13 to start rotating, so that the rotating rod 17 connected to the edge of the rotating disc 13 rotates, and when the rotating rod 17 rotates, it drives the movable rod 18 to move periodically left and right in the horizontal direction. When the movable rod 18 moves to the right, the slider at the top moves 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 die 9 to move to the right, until the movable die 9 abuts against the fixed die 10. At this time, the movable die 9 continuously moves to the right, so that the relative motion between the connecting rod 11 and the outer sleeve ring 41 occurs, the first spring 40 is compressed, and a thrust is generated on the movable die 9, so that the movable die 9 and the fixed die 10 always maintain close contact. When the connecting rod 11 moves, the driving rack 42 moves in the direction of the fixed die 10, until the driving rack 42 is deeply inserted into the inside of the slot 43. When the driving rack 42 moves to the deepest part of the inner slot, the trigger button 44 is extruded, at this time the movable die 9 receives the maximum thrust, and when the trigger button 44 is extruded, the electric hydraulic rod 31 is elongated, driving the piston 34 at the bottom to move to 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 of the liquid outlet 36, then flows into the infusion hole 28 through the liquid inlet pipe 29, and finally sprays into the inside of the die casting slot 26 through the spray hole 27, and performs die casting work on the workpiece. After die casting is completed, the movable die 9 moves reversely, at this time the driving rack 42 is separated from the trigger button 44, so that the electric hydraulic rod 31 resets, driving the piston 34 to move upward, generating negative pressure in the inside of the hydraulic chamber 33. When the piston 34 moves above the liquid inlet 35, the metal solution in the inner liquid groove 32 is again filled into the inside of the hydraulic chamber 33 under the action of negative pressure. Through the above steps, continuous automatic filling of the metal solution can be realized, and the die casting efficiency is effectively improved.

[0033] When the driving rack 42 moves to the right, the transmission gear 45 meshing with it starts to rotate, 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, the connecting rod moves, and when the connecting rod moves, the limiting rod 47 moves, so that the limiting rod 47 is clamped into the inside of the limiting slot during die casting, thereby reducing the vibration between the movable die 9 and the fixed die 10 during die casting, avoiding deformation of the workpiece during die casting, and improving the die casting quality. By providing the sealing groove 48, the sealing property of the movable die 9 and the fixed die 10 during die casting can be improved, and the overflow of the metal solution under high pressure can be avoided.

[0034] When the movable table 6 moves right, the top rod 12 moves right, the mounting rod 49 moves, the clamping jaw 50 on the bottom moves, when the clamping jaw 50 moves and contacts the wedge-shaped top block 53, the clamping jaw 50 is pushed outward, the second spring 51 is stretched, when the clamping jaw 50 is closed, the clamping block 52 moves to the workpiece in the die casting groove 26, the workpiece is taken out, the movable rod 18 moves left, the lower slide rod 20 moves left, the movable rack 21 moves, the movable end of the lifting rod 22 rotates, the fixed end of the lifting rod 22 moves upward, the blanking plate moves upward along the guide bar 39, the workpiece is taken out by the clamping jaw 50, the workpiece falls on the surface of the blanking plate under the action of gravity, when the movable rack 21 moves right again, the lifting rod 22 shortens, the blanking plate and the workpiece 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 is stretched, the workpiece on the surface of the blanking plate is unloaded, through the above steps, the automatic blanking of the workpiece can be realized, and the workpiece can be prevented from being damaged due to the high height when falling.

[0035] When the workpiece is pushed out of the blanking plate and falls on the surface of the conveyor belt, the driving wheel starts to rotate when the rotating disc 13 rotates, the driven wheel 24 starts to rotate through the transmission chain 25, the transmission roller 23 starts to rotate, the conveyor belt starts to move, the workpiece on the surface of the conveyor belt is conveyed to the outside of the main body 1, the driving bevel gear 14 starts to rotate when the rotating disc 13 rotates, the driven bevel gear 15 starts to rotate, the rotating shaft starts to rotate, the blade 16 in the heat dissipation hole starts to rotate, wind power is generated, the workpiece is cooled, and automatic cooling during the conveying of the workpiece is realized, so that the workpiece is conveniently machined in the next step.
