[0011] A method for using a vacuum pump casting device comprises the following steps: S1. First, after the sand falling trough is filled, the driving motor is started to rotate for one circle. The driving motor drives the rotating rod to rotate. When the rotating rod rotates, the L-shaped rotating rod 1 on the side of the auxiliary rotating rod 1 is driven to rotate through the transmission belt 2. When the L-shaped rotating rod 1 rotates, it drives the rotating rod 1 to swing left and right on the surface of the supporting plate through the notch provided on the surface of the rotating rod 1. At the same time, when the rotating rod rotates, the transmission belt 1 drives the pulley 1 to rotate. The pulley 1 rotates through the cam plate. When the cam plate rotates, it drives the L-shaped rotating rod 2 to rotate. When the L-shaped rotating rod 2 rotates, it drives the rotating rod 2 to swing left and right on the surface of the supporting plate through the notch provided on the surface of the rotating rod 2. S2. When the rotating rod 1 and the rotating rod 2 swing to the left, the connecting rod 1 and the connecting rod 2 pull the L-shaped rod 1 and the L-shaped rod 2 to move to the left. The L-shaped rod 1 and the L-shaped rod 2 slide on the slide rail through the sliding block 1 and the sliding block 2 to make the L-shaped rod 1 and the L-shaped rod 2 move to the left. When the L-shaped rod 1 and the L-shaped rod 2 move, the horizontal plate 1 and the horizontal plate 2 are driven to move at the same time. When the horizontal plate 1 and the horizontal plate 2 move, the sleeve rod and the extrusion rod are driven to move at the same time. When the sleeve rod moves, the shovel plate is driven to move at the same time. When the shovel plate moves to the left, it will move on the surface of the sand falling trough, and push the excess sand on the surface of the sand falling trough filled with sand into the collection frame. At the same time, the sand will be pushed to the surface of the shovel plate by the reaction force of the shovel plate. S3, when the L-shaped rod 1 moves, it drives the telescopic push rod to move at the same time. When the telescopic push rod moves, it squeezes the slope of the inclined baffle. When the inclined baffle is squeezed, it moves upward inside the slide groove to block the two sides of the sand falling groove. At the same time, when the inclined baffle descends, it will not affect the die pressing, and the quality of the film pressing is guaranteed while preventing the sand from spilling. When the driving motor rotates half a circle, it drives the L-shaped rod 1 and the L-shaped rod 2 to move right. At this time, when the cam plate rotates, the concave part of the cam plate will rotate to one end of the Z-shaped rod and pull the Z-shaped rod at the same time. When one end of the Z-shaped rod is pulled, it will rotate with itself as the center of the circle, and the other end of the Z-shaped rod will be lifted. The other end of the Z-shaped rod drives the connecting rod to move upward at the same time. When the connecting rod moves upward, it pulls the slide rail to slide upward in the vertical slide groove. When the slide rail slides upward, it drives the L-shaped rod 1 and the L-shaped rod 2 to move upward at the same time, and drives the shovel plate to move upward at the same time; S4, when the slide rail slides upward, the moving range of connecting rod 1 and connecting rod 2 will be shortened, and sliding block 2 will approach sliding block 1. When sliding block 2 approaches, it will drive L-shaped rod 2 to move at the same time. When L-shaped rod 2 moves, it will drive cross plate 2 to move. When cross plate 2 moves, it will drive extrusion rod to move at the same time. The extrusion rod will slide inside the sleeve rod and squeeze the chute at the same time. When the chute is squeezed, the sleeve rod will rotate. At this time, the shovel plate has completely slid across the surface of the sand chute and stays at the upper end of the collection frame. When the sleeve rod rotates, it drives the shovel plate to rotate and tilt, so that the sand on the surface of the shovel plate will slide into the inside of the collection frame. When the drive motor is about to rotate one circle, the shovel plate will move to the right and return to the initial state. S5. When the auxiliary rotating rod 1 makes the shovel plate move to the left, the auxiliary rotating rod 1 drives the lower pulley to rotate through the belt 2. When the lower pulley rotates, the belt is transmitted to the upper pulley through the belt 1. When the belt 1 is transmitted, it drives the sliding bar on the surface to move upward at the same time. When the sliding bar moves, it drives the sliding plate to move upward through the horizontal slide groove. The sliding plate drives the pressure block to move upward. When the upper pulley and the lower pulley continue to rotate, the sliding bar will slide to the other side inside the horizontal slide groove and drive the pressure block to move downward, forming an up and down reciprocating motion to die-cast the sand until it returns to its initial state. In this way, die-casting can be carried out directly without overflowing the sand, which saves a lot of time and improves work efficiency. The other end is driven by the auxiliary rotating rod 1 and the auxiliary rotating rod 2 to ensure the overall balance of the device.

[0012] In the present invention, when the shovel plate moves, it moves on the surface of the sand falling trough, pushing the excess sand on the surface of the sand falling trough filled with sand into the collection frame. At the same time, the sand will also be pushed to the surface of the shovel plate by the reaction force of the shovel plate. In this way, cleaning up the excess sand can ensure the quality integrity of the model.

[0013] In the present invention, when the L-shaped rod moves, the telescopic push rod is driven to move simultaneously. When the telescopic push rod moves, the inclined surface of the inclined baffle plate is squeezed. When the inclined baffle plate is squeezed, it moves upward inside the chute to block the two sides of the sand falling chute, thereby preventing sand from spilling from the two sides when cleaning excess sand.

[0014] In the present invention, the extrusion rod slides inside the sleeve rod and squeezes the inclined groove. When the inclined groove is squeezed, the sleeve rod is driven to rotate, and the shovel plate completely slides over the surface of the sand falling chute and stays at the upper end of the collection frame. When the sleeve rod rotates, the shovel plate is driven to rotate and tilt, so that the sand on the surface of the shovel plate will slide into the inside of the collection frame, which can be recycled and reused while saving resources.

After the sand falling trough 74 is filled, the driving motor 41 is started to rotate for one circle. The driving motor 41 drives the rotating rod 42 to rotate. When the rotating rod 42 rotates, the L-shaped rotating rod 514 on the side of the auxiliary rotating rod 53 is driven to rotate through the transmission belt 515. When the L-shaped rotating rod 514 rotates, it drives the rotating rod 51 to swing left and right on the surface of the supporting plate 2 through the notch provided on the surface of the rotating rod 51. At the same time, when the rotating rod 42 rotates, the transmission belt 45 drives the pulley 44 to rotate. The pulley 44 rotates through the cam plate 43.

When the horizontal plate 1 61 and the horizontal plate 2 62 move, the sleeve rod 63 and the extrusion rod 65 move simultaneously. When the sleeve rod 63 moves, the shovel plate 66 moves simultaneously. When the shovel plate 66 moves to the left, it moves on the surface of the sand falling trough 74, pushing the excess sand on the surface of the sand falling trough 74 filled with sand into the collection frame 75. At the same time, the sand will also be pushed to the surface of the shovel plate 66 by the reaction force of the shovel plate 66.

When the inclined groove 64 is squeezed, the sleeve rod 63 will be driven to rotate. At this time, the shovel plate 66 has completely slid across the surface of the sand falling groove 74 and stays at the upper end of the collection frame 75. When the sleeve rod 63 rotates, the shovel plate 66 is driven to rotate and tilt, so that the sand on the surface of the shovel plate 66 will slide into the inside of the collection frame 75, which can be recycled and reused while saving resources. When the drive motor 41 is about to rotate one circle, the shovel plate 66 will move to the right and return to the initial state. When the upper and lower pulleys 81 and 82 are in a state of being moved upward, the slide bar 86 on the surface of the pulley 81 is driven by the auxiliary rotating rod 53 and the belt 84 is driven to rotate.

When the rotating rod (42) rotates, the L-shaped rotating rod (514) on the side of the auxiliary rotating rod (53) is driven to rotate through the transmission belt (515). When the L-shaped rotating rod (514) rotates, the rotating rod (51) is driven to swing left and right on the surface of the support plate (2) through the notch provided on the surface of the rotating rod (51). At the same time, when the rotating rod (42) rotates, the belt pulley (44) is driven to rotate through the transmission belt (45). The belt pulley (44) rotates through the cam plate (43). When the cam plate (43) rotates, the L-shaped rotating rod (55) is driven to rotate. When the L-shaped rotating rod (55) rotates, the notch provided on the surface of the rotating rod (52) is driven to swing left and right on the surface of the support plate (2); S2. When the rotating rod 1 (51) and the rotating rod 2 (52) swing to the left, the L-shaped rod 1 (512) and the L-shaped rod 2 (513) are pulled to move to the left through the connecting rod 1 (56) and the connecting rod 2 (57). The L-shaped rod 1 (512) and the L-shaped rod 2 (513) slide on the slide rail (59) through the sliding block 1 (510) and the sliding block 2 (511), so that the L-shaped rod 1 (512) and the L-shaped rod 2 (513) move to the left. When the L-shaped rod 1 (512) and the L-shaped rod 2 (513) move, The first transverse plate (61) and the second transverse plate (62) move simultaneously. When the first transverse plate (61) and the second transverse plate (62) move, the sleeve rod (63) and the extrusion rod (65) move simultaneously. When the sleeve rod (63) moves, the shovel plate (66) moves simultaneously. When the shovel plate (66) moves to the left, it moves on the surface of the sand falling trough (74), pushing the excess sand on the surface of the sand falling trough (74) filled with sand into the collection frame (75). At the same time, the sand is also pushed to the surface of the shovel plate (66) by the reaction force of the shovel plate (66); S3. When the L-shaped rod 1 (512) moves, the telescopic push rod (73) is driven to move at the same time. When the telescopic push rod (73) moves, it squeezes the inclined surface of the inclined baffle (72). When the inclined baffle (72) is squeezed, it moves upward inside the chute (71) to block the two sides of the sand falling chute (74). At the same time, when the inclined baffle (72) descends, it will not affect the die pressing. While preventing sand from spilling, it also ensures the quality of the die pressing. When the driving motor (41) rotates half a circle, it will drive the L-shaped rod 1 (512) and the L-shaped rod 2 (513) to move to the right. At this time, the cam plate (43) rotates When the cam plate (43) is moved upward, the concave part of the cam plate (43) will rotate to one end of the Z-shaped rod (46), and the Z-shaped rod (46) will be pulled at the same time. When one end of the Z-shaped rod (46) is pulled, it will rotate around itself as the center of the circle, and the other end of the Z-shaped rod (46) will be lifted. At the same time, the other end of the Z-shaped rod (46) will drive the connecting rod (47) to move upward at the same time. When the connecting rod (47) moves upward, it will pull the slide rail (59) to slide upward in the vertical slide groove (58). When the slide rail (59) slides upward, it will drive the L-shaped rod 1 (512) and the L-shaped rod 2 (513) to move upward at the same time, and drive the shovel plate (66) to move upward at the same time. S4. When the slide rail (59) slides upward, the moving ranges of the connecting rod 1 (56) and the connecting rod 2 (57) are shortened, and the sliding block 2 (511) is moved closer to the sliding block 1 (510). When the sliding block 2 (511) is moved closer, the L-shaped rod 2 (513) is driven to move at the same time. When the L-shaped rod 2 (513) moves, the cross plate 2 (62) is driven to move. When the cross plate 2 (62) moves, the extrusion rod (65) is driven to move at the same time. The extrusion rod (65) slides inside the sleeve rod (63) and squeezes the sleeve rod (63). The inclined groove (64) is pressed. When the inclined groove (64) is squeezed, the sleeve rod (63) is driven to rotate. At this time, the shovel plate (66) has completely slid across the surface of the sand falling groove (74) and stays at the upper end of the collection frame (75). When the sleeve rod (63) rotates, the shovel plate (66) is driven to rotate and tilt, so that the sand on the surface of the shovel plate (66) slides into the inside of the collection frame (75). When the driving motor (41) is about to rotate one circle, the shovel plate (66) moves to the right and returns to the initial state; S5. When the auxiliary rotating rod 1 (53) causes the shovel plate (66) to move to the left, the auxiliary rotating rod 1 (53) drives the lower pulley (82) to rotate through the belt 2 (84). When the lower pulley (82) rotates, the belt is transmitted to the upper pulley (81) through the belt 1 (83). When the belt 1 (83) is transmitted, the sliding rod (86) on the surface is driven to move upward at the same time. When the sliding rod (86) moves, it drives the sliding plate (32) to move upward through the transverse sliding groove (85). The sliding plate (32) drives the pressing block (33). When the upper pulley (81) and the lower pulley (82) continue to rotate, the slide bar (86) will slide to the other side inside the transverse slide groove (85) and drive the pressing block (33) to move downward, forming an up and down reciprocating motion to die-cast the sand until it returns to its initial state. In this way, die-casting can be carried out directly without overflowing the sand, thus saving a lot of time and improving work efficiency. The other end is driven by the auxiliary rotating rod 1 (53) and the auxiliary rotating rod 2 (54) to ensure the overall balance of the device.
