Description

Technical Field

[0001] This invention relates to the field of mold storage equipment technology, and in particular to a mold frame for placing molds. Background Technology

[0002] Mold frames are suitable for storing molds in various manufacturing industries such as injection molding, stamping, die casting, and forging. In manufacturing, especially in mold-intensive production fields, molds are core production equipment, and the rationality of their storage and placement directly affects production efficiency, mold life and operational safety.

[0003] The existing mold rack includes a support frame and a placement rack fixed to the support frame. When in use, the mold is placed on the placement rack for storage.

[0004] In the above structure, due to the high level of dust on the ground in the factory environment and the close proximity of the placement rack to the ground, when the mold is placed for a long time, the dust adsorbed on the surface of the mold comes into contact with the moisture on the ground to form dirt. Long-term adhesion will cause corrosion on the metal surface of the mold, thus shortening the service life of the mold. Summary of the Invention

[0005] In order to place the mold further away from the ground, the present invention provides a mold frame for placing the mold.

[0006] This invention provides a mold frame for placing molds, employing the following technical solution: A mold holder for placing molds includes a support frame and a placement frame mounted on the support frame, and further includes a lifting mechanism mounted on the support frame for driving the placement frame away from the ground to lift the mold placed on the placement frame, a dust cover mounted on the support frame for covering the mold after the mold is lifted, and an adsorption mechanism mounted on the placement frame for adsorbing dust on the surface of the mold when the placement frame is lifted. The lifting mechanism includes a first threaded rod rotatably mounted on the support frame and threadedly connected to the placement frame, and a drive source mounted on the support frame for driving the first threaded rod to rotate. The support frame has lifting holes for vertical displacement of the placement frame, thereby restricting the rotation of the placement frame and guiding its movement.

[0007] By adopting the above technical solution, after the mold is placed on the placement rack, the first threaded rod is driven to rotate by the drive source. When the first threaded rod rotates, it drives the placement rack connected to it to move along the lifting hole, so that the mold is away from the ground. When the placement rack is raised and lowered, the adsorption mechanism is activated simultaneously to adsorb the dust on the surface of the mold, so that the raising and lowering and dust removal are carried out simultaneously. When the mold is raised and lowered to fit against the dust cover, the drive source stops working and the mold remains stationary and located inside the dust cover to protect the mold from dust.

[0008] Optionally, the first threaded rod is symmetrically arranged on both sides of the placement frame to avoid the lifting path of the placement frame on the support frame. The support frame has a loading station near the ground for loading molds and a dustproof station away from the ground for storing molds. The drive source is a dual-output shaft motor. The lifting mechanism also includes a rotating shaft connected to the output end of the drive source and a helical gear assembly connecting the rotating shaft and the first threaded rod for vertical transmission.

[0009] By adopting the above technical solution, the symmetrical arrangement of the first threaded rod ensures that the force on both sides is synchronized when the placement frame is raised and lowered, avoiding tilting and not interfering with the loading of the mold. The clear loading station and dustproof station make it easier to control the lifting and moving of the mold. At the same time, the helical gear assembly can transmit greater torque, and with the dual output shaft motor, it can easily drive the lifting of heavy molds.

[0010] Optionally, a rotary fan is mounted on the first threaded rod, and the rotary fan is driven by the first threaded rod to blow air upwards; The support frame is provided with an air supply channel, and the air supply channel is provided with an air supply hole; the dust cover is installed on the support frame, and the dust cover is provided with an air inlet channel through which air is supplied, and the air inlet channel is provided with an air inlet hole. The air supply hole and the air inlet hole are directly opposite each other, so that the air generated by the rotating fan is output from the air supply channel and transported to the air inlet channel through the air supply hole and the air inlet hole, so as to blow the dust on the surface of the mold into the adsorption mechanism.

[0011] By adopting the above technical solution, when the first threaded rod rotates, it will drive the rotary fan to rotate and generate upward air. At this time, the upward air generated by the rotary fan will be output through the air supply channel. Since the air supply hole and the air inlet hole are directly opposite each other, the air output by the air supply channel is transported to the air inlet channel through the air supply hole and the air inlet hole. The air inlet channel blows the air out toward the mold surface to blow the dust on the mold surface into the adsorption mechanism.

[0012] Optionally, a variable speed air supply mechanism is provided between the first threaded rod and the rotary fan; the variable speed air supply mechanism includes a drive shaft installed in the air supply channel, a first large gear installed on the first threaded rod, a first small gear fixedly installed on the drive shaft and meshing with the first large gear, a second large gear fixedly installed on the drive shaft, and a second small gear meshing with the second large gear; the rotary fan is rotatably sleeved on the outside of the first threaded rod and coaxially fixedly connected to the second small gear, so as to increase the rotational speed of the rotary fan through gear speed transmission.

[0013] By adopting the above technical solution, when the first threaded rod rotates, it drives the first large gear to rotate. The rotation of the first large gear drives the first small gear meshing with it to rotate, which in turn drives the transmission shaft to rotate. When the transmission shaft rotates, it drives the second large gear to rotate. When the second large gear rotates, it drives the second small gear to rotate. When the second small gear rotates, it drives the rotating fan coaxially connected with it to rotate. The speed of the rotating fan is increased by the two-stage gear speed increase, thereby generating stronger wind force.

[0014] Optionally, the adsorption mechanism includes a drive roller slidably mounted on the support frame and passing through the placement frame, an electrostatic dust collection component mounted on the drive roller for adsorbing dust, a dust collection component mounted on the placement frame for collecting the dust adsorbed by the electrostatic dust collection component, and a gear and rack assembly for driving the drive roller to rotate when the placement frame is raised and lowered. The gear and rack assembly includes a drive gear mounted on the transmission roller and a drive rack mounted on the support frame and vertically arranged along the lifting direction of the placement frame; the drive gear meshes with the drive rack.

[0015] By adopting the above technical solution, when the placement rack is raised and lowered, the drive gear and drive rack drive the transmission roller to rotate. When the transmission roller rotates, it drives the electrostatic dust collection component to work and adsorb the dust on the surface of the mold. At the same time, the dust adsorbed by the electrostatic dust collection component is collected by the dust collection component to avoid dust damaging the mold.

[0016] Optionally, the electrostatic dust collection assembly includes a rotating plate circumferentially mounted on the drive roller, a rubber friction plate telescopically mounted on the rotating plate, and a compression spring mounted between the rotating plate and the rubber friction plate; the compression spring drives the rubber friction plate to always tend to move away from the drive roller; The support frame has a friction contact area that abuts against the rubber friction plate, the top of the placement frame has a dust adsorption area, and one side of the placement frame has a static electricity elimination area; When the transmission roller rotates, the rubber friction plate generates static electricity by rubbing against the support frame in the friction contact area. Then, the dust is attracted by static electricity in the dust adsorption area, and finally, the static electricity is eliminated in the static elimination area.

[0017] By adopting the above technical solution, when the transmission roller rotates, it will drive the rotating plate and the rubber friction plate to rotate synchronously. When the rubber friction plate rotates, it will first rub against the friction contact area and the support frame to generate static electricity. Then it will continue to rotate to the dust adsorption area and adsorb the dust through the generated static electricity. After that, it will continue to rotate to the static electricity elimination area to eliminate the static electricity, so as to facilitate the cleaning of the dust adsorbed on the rubber friction plate.

[0018] Optionally, the placement rack has a dust collection area, and the dust collection assembly is located in the dust collection area; the dust collection assembly includes a dust collection plate slidably mounted on the placement rack and a rubber baffle plate mounted on the dust collection plate; the dust collection plate has ventilation holes for air to pass through only; When the rubber friction plate rotates to the dust collection area, it comes into contact with the rubber baffle plate to shake the dust on the rubber friction plate onto the dust collection plate.

[0019] By adopting the above technical solution, when the rubber friction plate that adsorbs dust rotates to the dust collection area, it will come into contact with the rubber baffle plate to shake the dust adsorbed on the rubber friction plate into the dust collection plate. At the same time, the strong wind generated by the rotating fan will blow the dust on the mold surface into the dust collection plate, and the strong wind will be output from the vent and leave the dust in the dust collection plate, so as to make the dust cleaning on the mold surface more thorough.

[0020] Optionally, the placement frame is equipped with a clamping mechanism for clamping the mold, the clamping mechanism being symmetrically arranged on the placement frame; the clamping mechanism includes clamping blocks that are slidably mounted on the placement frame and clamp the mold from both sides of the placement frame, second threaded rods symmetrically arranged on the placement frame for driving the clamping blocks to move, and a synchronization component for driving the two second threaded rods to rotate synchronously; one of the second threaded rods has a rotating wheel installed at its end for easy manual rotation.

[0021] By adopting the above technical solution, after the mold is placed on the placement rack, the rotating wheel is rotated and driven by the synchronization component, so that the two second threaded rods rotate synchronously. When the second threaded rods rotate, they drive the clamping block connected to them to move, so that the clamping block fixes the mold and prevents the mold from falling when it is placed.

[0022] Optionally, a lifting and conveying mechanism for conveying the mold to the placement rack is installed on one side of the support frame; The lifting and conveying mechanism includes a lifting hydraulic cylinder mounted on the support frame, a lifting plate connected to the lifting hydraulic cylinder, a movable frame slidably mounted on the lifting plate, and a conveying structure mounted on the movable frame for conveying the mold.

[0023] By adopting the above technical solution, when the placement rack is located at the loading station, the mold is placed on the conveying structure. The lifting hydraulic cylinder is activated to drive the lifting plate to rise and fall. When the lifting plate rises and falls, it drives the moving frame and the conveying structure to rise and fall synchronously, so that the height of the conveying structure is slightly higher than that of the placement rack. Then, the conveying mechanism is activated to transport the mold to the placement rack.

[0024] Optionally, a slide rail is installed on the lifting plate, and the movable frame is slidably mounted on the slide rail so as to push the movable frame and the conveying structure to move along the slide rail toward the placement frame; The placement rack is rotatably mounted with auxiliary rollers to assist in conveying the mold onto the placement rack when the conveying structure transports the mold.

[0025] By adopting the above technical solution, when the height of the conveying structure is higher than that of the placement rack, the moving frame is pushed to move along the slide rail, so that the moving frame and the conveying structure move along the slide rail towards the placement rack. Then, the conveying structure is started to convey the mold. When the mold is conveyed, it will be moved with the help of auxiliary rollers so as to convey the mold to the placement rack.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. After the mold is placed on the placement rack, the first threaded rod is driven to rotate by the drive source. When the first threaded rod rotates, it drives the placement rack connected to it to move along the lifting hole, so that the mold is away from the ground. When the placement rack is raised and lowered, the adsorption mechanism is activated simultaneously to adsorb the dust on the surface of the mold, so that the raising and lowering and dust removal are carried out simultaneously. When the mold is raised to fit against the dust cover, the drive source stops working and the mold remains stationary and located inside the dust cover to protect the mold from dust. 2. When the drive roller rotates, it will drive the rotating plate and the rubber friction plate to rotate synchronously. When the rubber friction plate rotates, it will first rub against the friction contact area and the support frame to generate static electricity. Then it will continue to rotate to the dust adsorption area and use the generated static electricity to adsorb the dust. After that, it will continue to rotate to the static electricity elimination area to eliminate the static electricity, so as to facilitate the cleaning of the dust adsorbed on the rubber friction plate. 3. When the rubber friction plate that adsorbs dust rotates to the dust collection area, it will come into contact with the rubber baffle plate to shake the dust adsorbed on the rubber friction plate into the dust collection plate. At the same time, the strong wind generated by the rotating fan will blow the dust on the mold surface into the dust collection plate. The strong wind will also be output from the vent and leave the dust in the dust collection plate, so as to make the dust on the mold surface more thoroughly cleaned. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] This invention discloses a mold frame for placing molds.

[0031] Reference Figure 1 , Figure 2 as well as Figure 3 A mold holder for placing molds includes a support frame 1, a placement rack 2 mounted on the support frame 1, a lifting mechanism 5, a dust cover 7, a lifting and conveying mechanism 3, a clamping mechanism 4, and an adsorption mechanism 8. The support frame 1 has a loading station 11 and a dustproof station 12. The loading station 11 is the starting position, where the mold is loaded onto the placement rack 2. The dustproof station 12 is used for storing the mold.

[0032] A lifting mechanism 5 is mounted on the support frame 1 and is used to drive the placement rack 2 and the mold fixed on the placement rack 2 to rise and fall on the support frame 1, thereby driving the mold away from the ground. A dust cover 7 is mounted on the support frame 1 and is located at the dustproof station 12 to cover the mold for dust prevention when it is lifted. A lifting and conveying mechanism 3 is mounted on the support frame 1 and is used to convey the mold to the placement rack 2. A clamping mechanism 4 is mounted on the placement rack 2 and is used to clamp and fix the mold placed on the placement rack 2. An adsorption mechanism 8 is mounted on the support frame 1 and is used to adsorb dust from the surface of the mold placed on the placement rack 2 when the placement rack 2 is lifted and lowered.

[0033] During operation, the placement rack 2 is located at the loading station 11. The mold is then transported to the placement rack 2 via the lifting and conveying mechanism 3, and clamped and fixed by the clamping mechanism 4 installed on the placement rack 2. At this time, the lifting mechanism 5 is activated, causing the placement rack 2 and the mold to slide and rise within the support frame 1, raising them away from the ground. While the placement rack 2 and the mold are sliding and rising within the support frame 1, the adsorption mechanism 8 activates to adsorb dust from the mold surface, preventing dust from remaining on the mold. Simultaneously, when the placement rack 2 and the mold rise to the dustproof station 12, they come into contact with the dustproof cover 7, covering the mold on the placement rack 2 and providing protection.

[0034] Reference Figure 1 as well as Figure 4 The lifting and conveying mechanism 3 includes a U-shaped frame 31, a lifting hydraulic cylinder 32, a lifting plate 33, a moving frame 34, and a conveying structure 35.

[0035] The U-shaped frame 31 is fixedly mounted on the support frame 1. The lifting hydraulic cylinder 32 is fixedly mounted on the top wall of the inner cavity of the U-shaped frame 31. The lifting plate 33 is fixedly connected to the output end of the lifting hydraulic cylinder 32. The U-shaped frame 31 has a lifting hole 36 for vertical displacement of the lifting plate 33 to restrict the rotation of the lifting plate 33 and guide its movement. A slide rail 37 is fixedly mounted on the lifting plate 33. The moving frame 34 is slidably mounted on the slide rail 37 so as to push the moving frame 34 and the conveying structure 35 to move along the slide rail 37 towards the placement frame 2.

[0036] The conveying structure 35 is a conveyor belt, and the conveyor belt is driven by a motor built into the conveyor belt to facilitate the conveying of the mold on the conveyor belt. At the same time, the conveyor belt and the moving frame 34 are fixed together by locking bolts.

[0037] Reference Figure 3 as well as Figure 5The clamping mechanism 4 includes a clamping block 48, a second threaded rod 41, a rotating wheel 42, and a synchronization assembly 43. The synchronization assembly 43 includes two synchronization wheels 431 and a synchronization belt 432, which drives the two synchronization wheels 431 to rotate synchronously.

[0038] Two second threaded rods 41 are symmetrically arranged on the placement frame 2. Arc-shaped blocks 44 are symmetrically fixedly installed on the placement frame 2, and the outer sides of the two second threaded rods 41 are rotatably mounted between the corresponding arc-shaped blocks 44. A movable plate 45 is threadedly connected to the outer side of each second threaded rod 41. A movable block 46 is fixedly installed on the movable plate 45. A movable groove 47 is provided on the placement frame 2 to allow the movable block 46 to move horizontally, thereby limiting the rotation of the movable plate 45 and providing movement guidance. Four clamping blocks 48 are fixedly installed on the movable plate 45 and symmetrically arranged on the placement frame 2 to clamp and fix the mold around its perimeter.

[0039] One of the second threaded rods 41 has a rotating wheel 42 fixedly installed at its end, so as to drive the second threaded rod 41 to rotate through the rotating wheel 42. Two synchronous wheels 431 are fixedly installed on the corresponding two second threaded rods 41, so as to drive the two second threaded rods 41 to rotate synchronously through the synchronous belt 432.

[0040] Auxiliary rollers 49 are rotatably mounted on both second threaded rods 41 to assist in conveying the mold to the placement rack 2 during the conveying structure 35.

[0041] During operation, the mold to be placed is first placed on the conveyor belt. Then, the lifting hydraulic cylinder 32 is activated to drive the lifting plate 33 to rise and fall along the lifting hole 36, which in turn drives the moving frame 34 and the conveyor belt to rise and fall along the lifting hole 36, so that the height of the conveyor belt and the mold placed on the conveyor belt is higher than the height of the placement frame 2. At this time, the worker pushes the moving frame 34 to move closer to the placement frame 2. Then, the conveyor belt is activated to make the conveyor belt carry the mold to start conveying it closer to the placement frame 2, so that the mold comes into contact with the auxiliary roller 49 and generates thrust to push the mold closer to the placement frame 2, thus making it easier and more convenient for the mold to move to the placement frame 2.

[0042] When the mold is transported to the placement rack 2, the rotating wheel 42 drives the two second threaded rods 41 to rotate synchronously under the drive of the synchronous wheel 431 and the synchronous belt 432. This drives the moving plate 45, which is threadedly connected to the second threaded rods 41, to move along the moving groove 47. This causes the clamping block 48, which is fixedly installed with the moving plate 45, to start moving along the moving groove 47, so that the clamping block 48 clamps and fixes the mold around its perimeter.

[0043] Reference Figure 2 , Figure 3 as well as Figure 6 The lifting mechanism 5 includes a first threaded rod 51, a rotating shaft 52, a drive source 53, and a helical gear assembly 54. The helical gear assembly 54 includes a first helical gear 541 and a second helical gear 542. The first threaded rod 51 includes a lower threaded rod 511 and an upper rotating shaft 512, and flanges are fixedly installed at the ends of the lower threaded rod 511 and the upper rotating shaft 512 that are close to each other. The flanges are fixed by locking bolts to connect the lower threaded rod 511 and the upper rotating shaft 512 together.

[0044] The support frame 1 has a lifting hole 57 for vertical displacement of the placement frame 2, which restricts the rotation of the placement frame 2 and guides its movement. The support frame 1 has an air supply channel 13, within which a fixed base 14 is fixedly installed, and a drive source 53 is fixedly installed on the fixed base 14. A rotating shaft 52 is fixedly connected to the output end of the drive source 53 via a coupling. A support block 15 is fixedly installed on the air supply channel 13, and the rotating shaft 52 is rotatably mounted on the support block 15. A first helical gear 541 is fixedly installed on the rotating shaft 52, and a second helical gear 542 meshes with the first helical gear 541 and is fixedly installed on a lower threaded rod 511. Both the lower threaded rod 511 and the upper rotating shaft 512 are rotatably mounted on the air supply channel 13. A drive plate 55 is threadedly connected to the outer side of the lower threaded rod 511, and a lifting block 56 is fixedly installed on the drive plate 55. The lifting block 56 is fixedly installed on the placement frame 2 and slidably installed within the lifting hole 57. A guide plate 58 is fixedly installed inside the air supply duct 13, and a drive plate 55 is slidably sleeved on the outside of the guide plate 58 to restrict the rotation of the drive plate 55 and to guide its movement.

[0045] In this embodiment, the drive source 53 is a dual-output shaft motor, with synchronously rotating output ends at both ends. Furthermore, the number of the first threaded rod 51, helical gear assembly 54, rotating shaft 52, guide plate 58, and drive plate 55 are all two, symmetrically arranged on both sides of the support frame 1, to ensure greater stability when the dual-output shaft motor drives the placement frame 2 to rise and fall.

[0046] During operation, after the mold is fixed to the placement frame 2 by the clamping mechanism 4, the drive source 53 drives the rotating shaft 52 to rotate. The rotating shaft 52 drives the first helical gear 541 to rotate, and the first helical gear 541 drives the second helical gear 542, which meshes with it, to start rotating. The second helical gear 542 drives the lower threaded rod 511 to rotate, driving the drive plate 55, which is threadedly connected to the lower threaded rod 511, to move along the guide plate 58. At the same time, the drive plate 55 drives the lifting block 56 and the placement frame 2 to start moving along the lifting hole 57, so that the mold is away from the ground and avoids contact with the moisture on the ground. When the placement frame 2 moves to the dustproof station 12 and is in contact with the dustproof cover 7, the drive source 53 stops working and the placement frame 2 no longer moves, so that the dustproof cover 7 protects the mold fixed on the placement frame 2.

[0047] Reference Figure 3 as well as Figure 7 A rotary fan 6 is rotatably mounted on the upper rotating shaft 512, and the rotary fan 6 blows air upward when it rotates. A variable speed air supply mechanism 61 is connected between the lower threaded rod 511 and the rotary fan 6, so as to drive the rotary fan 6 to rotate and increase the speed of the rotary fan 6 when the lower threaded rod 511 rotates.

[0048] The variable speed air supply mechanism 61 includes a drive shaft 611, a first large gear 612, a first small gear 613, a second large gear 614, and a second small gear 615. Two limiting plates 616 are installed inside the air supply channel 13. The drive shaft 611 is rotatably mounted between the two limiting plates 616. The first large gear 612 is fixedly mounted on the outside of the lower threaded rod 511. The first small gear 613 is fixedly mounted on the outside of the drive shaft 611 and meshes with the first large gear 612. The second large gear 614 is fixedly mounted on the outside of the drive shaft 611. The second small gear 615 is fixedly mounted on the outside of the drive shaft 611 and meshes with the second large gear 614. A rotating cylinder 617 is fixedly mounted on the second small gear 615. A flange is mounted on one end of the rotating cylinder 617 near the rotating fan 6. The flange is fixed to the rotating fan 6 by locking bolts, so that the rotating fan 6 and the second small gear 615 are coaxially and fixedly connected, so that the rotational speed of the rotating fan 6 can be increased through gear transmission when the lower threaded rod 511 rotates.

[0049] An air supply hole 16 is provided on the air supply channel 13, and an air inlet channel 71 is provided on the dust cover 7 for air supply. An air inlet hole 72 is provided on the air inlet channel 71. The air supply hole 16 and the air inlet hole 72 are directly opposite each other. When the rotary fan 6 rotates, it generates an upward airflow. The airflow is output from the air supply channel 13 and transported to the air inlet channel 71 through the air supply hole 16 and the air inlet hole 72, thereby blowing it onto the mold surface to blow the dust on the mold surface into the adsorption mechanism 8.

[0050] During operation, when the drive source 53 drives the lower threaded rod 511 to rotate and drives the placement rack 2 and the mold to rise and fall, the lower threaded rod 511 also drives the first large gear 612 to rotate. The first large gear 612 drives the first small gear 613 meshing with it to start rotating. When the first small gear 613 rotates, it drives the transmission shaft 611 to rotate. When the transmission shaft 611 rotates, it drives the second large gear 614 to start rotating. When the second large gear 614 rotates, it drives the second small gear 615 meshing with it to start rotating. When the second small gear 615 rotates, it drives the rotating cylinder 617 to rotate. The rotating cylinder 617 drives the rotating fan 6 to rotate, which increases the rotation speed of the rotating fan 6 and thus makes the wind force generated by the rotating fan 6 stronger.

[0051] The strong wind generated by the rotating fan 6 flows upward in the air supply channel 13 and is delivered to the air inlet channel 71 through the air supply hole 16 and the air inlet hole 72. Then, the strong wind is blown to the surface of the lifting and lowering rack 2 and the mold through the air inlet channel 71, so as to blow the dust on the surface of the mold into the adsorption mechanism 8 to complete the dust removal.

[0052] Reference Figure 8 and Figure 9 The adsorption mechanism 8 includes a drive roller 81, an electrostatic dust collection component 82, a dust collection component 83, and a gear and rack assembly 84. The support frame 1 has a waist-shaped groove 17, and the drive roller 81 passes through the placement frame 2 and its end is slidably installed in the waist-shaped groove 17. An electrostatic dust collection assembly 82 is mounted on the drive roller 81 and is used to adsorb dust from the mold surface. A dust collection assembly 83 is mounted on the placement frame 2 and is used to collect the dust adsorbed by the electrostatic dust collection assembly 82. A gear and rack assembly 84 is mounted between the placement frame 2 and the drive roller 81 and is used to drive the drive roller 81 to rotate when the placement frame 2 is raised or lowered.

[0053] The electrostatic dust collection assembly 82 includes a rotating plate 821, a rubber friction plate 822, and a compression spring 823. The rotating plate 821 is circumferentially fixed on the drive roller 81, the rubber friction plate 822 is telescopically mounted on the rotating plate 821, and the compression spring 823 is fixedly connected between the rubber friction plate 822 and the rotating plate 821 to drive the rubber friction plate 822 to always tend to move away from the drive roller 81.

[0054] The support frame 1 has a friction contact area 18 that abuts against the rubber friction plate 822. The top of the placement frame 2 has a dust adsorption area 21, and one side of the placement frame 2 has a static electricity elimination area 22. The static electricity elimination area 22 is grounded through the metal support frame 1. When the transmission roller 81 rotates, the rotating rubber friction plate 822 generates static electricity by rubbing against the support frame 1 in the friction contact area 18. Then, when the statically charged rubber friction plate 822 rotates to the dust adsorption area 21, the static electricity on the surface of the mold is adsorbed by the static electricity on the rubber friction plate 822. Finally, when the rubber friction plate 822 rotates to the static electricity elimination area 22, the static electricity on the rubber friction plate 822 is eliminated.

[0055] The placement rack 2 has a dust collection area 23, and the dust collection assembly 83 is located in the dust collection area 23. The dust collection assembly 83 includes a dust collection plate 831 and a rubber baffle 832. T-shaped slide bars are fixedly installed on both sides of the dust collection plate 831, and slide grooves matching the T-shaped slide bars are opened on both sides of the placement rack 2 to slide the dust collection plate 831 onto the placement rack 2. The end of the rubber baffle 832 away from the drive roller 81 is fixedly installed inside the dust collection plate 831. The dust collection plate 831 has vent holes 833 for air to pass through only.

[0056] When the rubber friction plate 822 rotates to the dust collection area 23, it will come into contact with the rubber baffle plate 832 to shake the dust on the rubber friction plate 822 into the dust collection plate 831 for dust collection.

[0057] The gear and rack assembly 84 includes a drive rack 841 and a drive gear 842. The drive rack 841 is fixedly mounted on the support frame 1 and is vertically arranged along the lifting direction of the placement frame 2. The drive gear 842 is fixedly mounted on the transmission roller 81 and meshes with the drive rack 841.

[0058] During operation, when the drive source 53 drives the placement rack 2 to rise and fall, it drives the transmission roller 81 to rise and fall synchronously along the waist-shaped groove 17. At this time, the drive gear 842 fixedly installed on the transmission roller 81 will mesh with the drive rack 841, thereby driving the transmission roller 81 to rotate. When the transmission roller 81 rotates, it will drive the rotating plate 821 and the rubber friction plate 822 to rotate synchronously, so that the rubber friction plate 822 rubs against the support frame 1 in the friction contact area 18, generating static electricity. When the rubber friction plate 822 with static electricity rotates to the dust adsorption area 21, it will adsorb the dust on the surface of the mold through electrostatic attraction. When the rubber friction plate 822 with adsorbed dust rotates to the static electricity elimination area 22, the static electricity of the rubber friction plate 822 will be eliminated. When the rubber friction plate 822 with eliminated static electricity rotates to the dust collection area 23, the rubber friction plate 822 will collide and abut with the rubber baffle plate 832, and the dust will fall into the dust collection plate 831 for collection under the impact force. At the same time, when the strong wind from the air inlet channel 71 blows the dust on the surface of the mold into the dust collection plate 831, the strong wind will be dissipated through the vent 833 while the dust remains in the dust collection plate 831.

[0059] After the dust collection plate 831 has been used for a long time, simply remove it from the shelf 2, clean off the dust, and then reinsert it into the shelf 2.
