[0002] As a device widely used in many fields such as industrial production and scientific research experiments, the performance of a vacuum pump directly affects the effects and quality of related processes. In electronic manufacturing, a high-vacuum environment is required for precision operations such as chip lithography and coating, and the stable operation and efficient air extraction ability of the vacuum pump are crucial; in chemical production, the vacuum pump is used for processes such as vacuum distillation and gas separation to ensure that the reaction can proceed smoothly under specific pressure conditions.

[0003] The existing patent (publication number: CN112059154B) discloses a self-priming pump pump body sand casting demoulding device, including a sand falling groove, an upper sand box and a lower sand box; the lower sand box is filled with sand material, filled completely and smoothed, then the lower bottom plate is taken out, and the lower bottom plate is fixed on the lower sand box. At this time, the rotating motor drives the rotating support shaft to rotate, so as to turn the whole lower sand box over, so that the lower bottom plate is located below the lower sand box, and the lifting motor drives the lower sand box and the lower bottom plate to move downward until the fixed seat is aligned with the fixed sticker plate. The above-mentioned self-priming pump pump body sand casting demoulding device drives the upper sand box and the lower sand box to coincide and align, fills sand material into the upper sand box, and then takes out the mold frame; after taking out, it drives the upper top plate and the upper sand box to move downward again, and the casting cavity is formed for filling and casting. After the casting is formed, the casting is taken out; the lower sand box is reset, the lower bottom plate is removed, and the sand material is tamped out from the upper sand box and the lower sand box with a tamping rod, and falls onto the filter screen, and the sand material is filtered and then falls into the sand material groove for recycling.

The sliding rod is slidably connected inside the transverse chute.

[0012] A method for using a vacuum pump casting device includes the following steps:

[0013] S1. First, after filling the sand dropping groove, start the driving motor to rotate one week. The driving motor drives the rotating rod to rotate. When the rotating rod rotates, through the second transmission belt, it drives the L-shaped first rotating rod on the side surface of the first auxiliary rotating rod to rotate. When the L-shaped first rotating rod rotates, through the notch formed on the surface of the first rotating rod, it drives the first rotating rod to swing left and right on the surface of the support plate. At the same time, when the rotating rod rotates, it drives the first pulley to rotate through the first transmission belt. The first pulley rotates through the cam disc. When the cam disc rotates, it drives the L-shaped second rotating rod to rotate. When the L-shaped second rotating rod rotates, through the notch formed on the surface of the second rotating rod, it drives the second rotating rod to swing left and right on the surface of the support plate;

[0014] S2. When the first rotating rod and the second rotating rod swing to the left, through the first connecting rod and the second connecting rod, they pull the first L-shaped rod and the second L-shaped rod to move leftward. The first L-shaped rod and the second L-shaped rod slide on the slide rail through the first sliding block and the second sliding block, so that the first L-shaped rod and the second L-shaped rod move leftward. When the first L-shaped rod and the second L-shaped rod move, they drive the first cross plate and the second cross plate to move simultaneously. When the first cross plate and the second cross plate move, they drive the sleeve rod and the extrusion rod to move simultaneously. When the sleeve rod moves, it drives the shoveling plate to move simultaneously. When the shoveling plate moves leftward, it moves on the surface of the sand dropping groove, pushing the excess sand on the surface of the sand dropping groove filled with sand into the collection box. At the same time, the sand will also be pushed to the surface of the shoveling plate by the reaction force of the shoveling plate;

[0015] S3. At the same time, when the first L-shaped rod moves, it drives the telescopic push rod to move simultaneously. When the telescopic push rod moves, it will squeeze the inclined surface of the inclined baffle. When the inclined baffle is squeezed, it will move upward inside the chute, blocking both sides of the sand dropping groove. At the same time, when the inclined baffle descends, it will not affect the mold pressing. While preventing sand from spilling, it also ensures the quality of the mold pressing. When the driving motor rotates half a week, it will drive the first L-shaped rod and the second L-shaped rod to move to the right. At this time, when the cam disk rotates, the concave part of the cam disk 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 around its own center, and the other end of the Z-shaped rod will lift. The other end of the Z-shaped rod will drive the connecting rod to move upward at the same time. When the connecting rod moves upward, it will pull the slide rail to slide upward in the vertical chute. When the slide rail slides upward, it will drive the first L-shaped rod and the second L-shaped rod to move upward at the same time, and drive the shovel plate to move upward at the same time;

[0016] S4. When the slide rail slides upward, it will shorten the moving intervals of the first connecting rod and the second connecting rod. At the same time, the second sliding block will move closer to the first sliding block. When the second sliding block moves closer, it will drive the second L-shaped rod to move at the same time. When the second L-shaped rod moves, it will drive the second cross plate to move. When the second cross plate moves, it will drive the extrusion rod to move at the same time. The extrusion rod will slide inside the sleeve rod and squeeze the inclined groove at the same time. When the inclined groove is squeezed, it will drive the sleeve rod to rotate. At this time, the shovel plate has completely slid across the surface of the sand dropping groove and stays at the upper end of the collection box. When the sleeve rod rotates, it will drive the shovel plate to rotate and tilt, so that the sand on the surface of the shovel plate will slide into the collection box. When the driving motor is about to rotate one week, it will make the shovel plate move to the right and return to its initial state;

[0017] S5. When the first auxiliary rotating rod makes the shovel plate move to the left, the first auxiliary rotating rod drives the lower belt pulley to rotate through the second belt. When the lower belt pulley rotates, it drives the upper belt pulley through the first belt. When the first belt drives, it drives the sliding rod on its surface to move upward at the same time. When the sliding rod moves, it will drive the sliding plate to move upward through the horizontal chute. The sliding plate drives the pressing block to move upward. When the upper belt pulley and the lower belt pulley continue to rotate, the sliding rod will slide to the other side inside the horizontal chute and drive the pressing block to move downward, forming an up-and-down reciprocation to press the sand into a mold until it returns to its initial state. In this way, die casting can be directly carried out without ensuring that the sand overflows, saving a lot of time and improving work efficiency. The other end is driven by the first auxiliary rotating rod and the second auxiliary rotating rod to ensure the overall balance of the device.

[0018] In the present invention, when the shovel plate moves, it will move on the surface of the sand dropping groove, pushing the excess sand on the surface of the sand dropping groove filled with sand into the collection box. 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 the excess sand can ensure the integrity of the quality of the model.

[0019] In the present invention, when the first L-shaped rod moves, it drives the telescopic push rod to move simultaneously. When the telescopic push rod moves, it will squeeze the inclined surface of the inclined surface baffle. When the inclined surface baffle is squeezed, it will move upward inside the chute, blocking both sides of the sand dropping groove to prevent sand from spilling from both sides when cleaning the excess sand.

[0020] In the present invention, the extrusion rod will slide inside the sleeve rod and squeeze the inclined groove. When the inclined groove is squeezed, it will drive the sleeve rod to rotate. The shoveling plate completely slides across the surface of the sand dropping groove and stays at the upper end of the collection box. When the sleeve rod rotates, it drives the shoveling plate to rotate and tilt, so that the sand on the surface of the shoveling plate will slide into the collection box. While recycling resources, it can also be reused. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The use method and advantages of the present invention: The use method of the vacuum pump casting device, when in use, the working process is as follows:

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown;

[0043] A method for using a vacuum pump casting device comprises the following steps:

[0044] S1. First, fill the sand - dropping groove 74. Then, start the driving motor 41 to rotate one full circle. The driving motor 41 drives the rotating rod 42 to rotate. When the rotating rod 42 rotates, through the second transmission belt 515, it drives the L - shaped rod one 514 on the side of the auxiliary rotating rod one 53 to rotate. When the L - shaped rod one 514 rotates, through the notch on the surface of the rotating rod one 51, it drives the rotating rod one 51 to swing left and right on the surface of the support plate 2. At the same time, when the rotating rod 42 rotates, it drives the pulley one 44 to rotate through the first transmission belt 45. The pulley one 44 rotates through the cam disc 43. When the cam disc 43 rotates, it drives the L - shaped rod two 55 to rotate. When the L - shaped rod two 55 rotates, through the notch on the surface of the rotating rod two 52, it drives the rotating rod two 52 to swing left and right on the surface of the support plate 2;

[0045] S2. When the rotating rod one 51 and the rotating rod two 52 swing to the left, through the connecting rod one 56 and the connecting rod two 57, they pull the L - shaped rod one 512 and the L - shaped rod two 513 to move to the left. The L - shaped rod one 512 and the L - shaped rod two 513 slide on the slide rail 59 through the slider one 510 and the slider two 511, so that the L - shaped rod one 512 and the L - shaped rod two 513 move to the left. When the L - shaped rod one 512 and the L - shaped rod two 513 move, they drive the cross - plate one 61 and the cross - plate two 62 to move simultaneously. When the cross - plate one 61 and the cross - plate two 62 move, they drive the sleeve rod 63 and the extrusion rod 65 to move simultaneously. When the sleeve rod 63 moves, it drives the shovel plate 66 to move simultaneously. When the shovel plate 66 moves to the left, it will move on the surface of the sand - dropping groove 74, pushing the excess sand on the surface of the filled sand - dropping groove 74 into the collection box 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. In this way, cleaning the excess sand can ensure the integrity of the model quality;

[0046] S3. At the same time, when the L - shaped rod one 512 moves, it drives the telescopic push rod 73 to move simultaneously. When the telescopic push rod 73 moves, it will squeeze the inclined surface of the inclined - surface baffle 72. When the inclined - surface baffle 72 is squeezed, it will move upward inside the chute 71, blocking both sides of the sand - dropping groove 74 to prevent sand from spilling from both sides when cleaning the excess sand. At the same time, when the inclined - surface baffle 72 descends, it will not affect the die - pressing. While preventing sand from spilling, it also ensures the quality of die - pressing. When the driving motor 41 rotates one and a half circles, it will drive the L - shaped rod one 512 and the L - shaped rod two 513 to move to the right. At this time, when the cam disc 43 rotates, the concave part of the cam disc 43 will rotate to one end of the Z - shaped rod 46, and at the same time, it will pull the Z - shaped rod 46. When one end of the Z - shaped rod 46 is pulled, it will rotate around itself, and the other end of the Z - shaped rod 46 will lift. The other end of the Z - shaped rod 46 will drive the connecting rod 47 to move upward simultaneously. When the connecting rod 47 moves upward, it will pull the slide rail 59 to slide upward in the vertical chute 58. When the slide rail 59 slides upward, it drives the L - shaped rod one 512 and the L - shaped rod two 513 to move upward simultaneously, and drives the shovel plate 66 to move upward simultaneously;

[0047] S4. When the slide rail 59 slides upward, the moving intervals of the first connecting rod 56 and the second connecting rod 57 will be drawn closer. At the same time, the second slider 511 will move closer to the first slider 510. When the second slider 511 moves closer, it will drive the second L-shaped rod 513 to move simultaneously. When the second L-shaped rod 513 moves, it will drive the second cross plate 62 to move. When the second cross plate 62 moves, it will drive the extrusion rod 65 to move simultaneously. The extrusion rod 65 will slide inside the sleeve rod 63 and simultaneously squeeze the inclined groove 64. When the inclined groove 64 is squeezed, it will drive the sleeve rod 63 to rotate. At this time, the shovel plate 66 has completely slid over the surface of the sand discharge groove 74 and stays at the upper end of the collection box 75. When the sleeve rod 63 rotates, it will drive the shovel plate 66 to rotate and tilt, so that the sand on the surface of the shovel plate 66 will slide into the interior of the collection box 75, achieving resource recovery and reuse while saving resources. When the drive motor 41 is about to rotate one week, it will cause the shovel plate 66 to move to the right and return to its initial state;

[0048] S5. When the first auxiliary rotating rod 53 moves the shovel plate 66 to the left, the first auxiliary rotating rod 53 drives the lower belt pulley 82 to rotate through the second belt 84. When the lower belt pulley 82 rotates, it drives the upper belt pulley 81 through the first belt 83. When the first belt 83 is driven, it drives the slide rod 86 on its surface to move upward simultaneously. When the slide rod 86 moves, it will drive the slide plate 32 to move upward through the horizontal slide groove 85. The slide plate 32 drives the pressing block 33 to move upward. When the upper belt pulley 81 and the lower belt pulley 82 continue to rotate, the slide rod 86 will slide to the other side inside the horizontal slide groove 85 and drive the pressing block 33 to move downward, forming an up-and-down reciprocation to press the sand into shape until it returns to its initial state. In this way, the sand can be directly pressed without overflowing, saving a lot of time and improving work efficiency.

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, while preventing sand from falling, it also ensures the quality of the die. When the drive 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.

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.
