Description
Technical Field
[0001] This utility model belongs to the field of mold processing technology, specifically a mold processing fixing device. Background Technology
[0002] A mold processing fixing device is a specially designed device for fixing and clamping during mold processing. Its main function is to firmly fix the mold on the worktable and prevent the mold from shifting or loosening due to vibration, impact or other factors during processing, thereby ensuring the accuracy and quality of mold processing.
[0003] Mold processing fixing devices generally consist of a fixed base, a sliding frame, a clamping mechanism, etc. Among them, the clamping mechanism is one of the core parts of the mold processing fixing device, and it is usually composed of threaded rods, rubber sleeves, adjusting bolts, etc.
[0004] Existing mold processing fixing devices typically use a pair of clamping plates to hold and fix the mold during use. However, through long-term use and observation, it has been found that when the mold is irregularly shaped, the clamping plates are unable to provide sufficient clamping force, which can cause the mold to shake during processing and thus affect the processing work. Therefore, a mold processing fixing device is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and address the problems of existing equipment, this utility model proposes a mold processing fixing device.
[0006] The technical solution adopted by this utility model to solve its technical problem is a mold processing fixing device, including an operating table. A pair of first linear motors are fixedly connected to the operating table. A first slider is fixedly connected to the output end of the first linear motor. A support column is fixedly connected to the first slider. A connecting column is fixedly connected between the pair of support columns. A second linear motor is fixedly connected to the connecting column. A second slider is fixedly connected to the output end of the second linear motor. A grinding tool is provided on the second slider. A pair of fixed seats are fixedly connected to the operating table. A hydraulic cylinder is fixedly connected to the fixed seats. A first fixed plate is fixedly connected to the output end of the hydraulic cylinder. The first fixed plate is a hollow structure, and multiple springs are fixedly connected to the first fixed plate. The first fixed plate has multiple connecting holes, which correspond to the spring telescopic rods. The spring telescopic rods are connected to the first fixed plate. An air tank is fixed to the hydraulic cylinder, and an air pump is installed on the air tank. An air supply pipe is connected to the air tank and is connected to the first fixed plate. The air supply pipe is equipped with a pressure relief valve. By fixing multiple spring telescopic rods to the first fixed plate, when the first fixed plate moves to a designated position, the multiple spring telescopic rods fixed to the first fixed plate contact the mold surface, which can clamp and fix irregularly shaped molds, reducing the difficulty of fixing irregularly shaped molds.
[0007] Preferably, the operating table is provided with multiple sliding grooves, and multiple guide blocks are fixedly connected to the first fixed plate. The sliding grooves and guide blocks are arranged correspondingly. By fixing multiple guide blocks to the first fixed plate and providing multiple sliding grooves on the operating table, when the first fixed plate moves, it drives the guide blocks to slide inside the sliding grooves, which makes the movement of the first fixed plate more stable and reduces the shaking of the first fixed plate during use, thus preventing the spring telescopic rod from loosening its fixation on the mold.
[0008] Preferably, multiple second fixing plates are fixedly connected to the operating table, multiple third fixing plates are fixedly connected to the first fixing plate, and multiple sets of guide strips are fixedly connected to the operating table. The third fixing plates and guide strips are in sliding fit. The slide groove is located between a set of guide strips. An elastic cloth is fixedly connected between the second fixing plates and the third fixing plates. By fixing the elastic cloth between the second fixing plates and the third fixing plates, when the elastic cloth is stretched, it covers the slide groove, which can reduce the falling of debris and impurities generated during the processing of the mold into the slide groove, thus preventing the slide groove from moving and getting stuck inside the guide block.
[0009] Preferably, a plurality of balls are rotatably connected to the guide block. The balls are arranged in an array and are located between the guide block and the slide groove. By rotatably connecting a plurality of balls to the guide block, the balls roll on the inner wall of the slide groove when the guide block moves in the slide groove, which makes the guide block move more smoothly inside the slide groove and reduces the possibility of the guide block not moving smoothly inside the slide groove.
[0010] Preferably, a connecting seat is fixedly connected to the end of the spring telescopic rod, and a slot is provided on the connecting seat. A pressing block is rotatably connected in the slot. By rotatably connecting the pressing block in the slot, the situation where the spring telescopic rod cannot better fit the mold surface due to the inability to adjust the contact angle between the spring telescopic rod and the mold surface during use can be reduced.
[0011] Preferably, a rubber block is fixed to the pressing block. The rubber block is made of a flexible material. By fixing the rubber block to the pressing block, the friction between the pressing block and the mold surface can be increased, reducing the situation where the mold shakes due to insufficient friction during use. At the same time, it can reduce the situation where the pressing block directly contacts the mold surface during use, causing scratches on the mold surface.
[0012] The advantages of this utility model are:
[0013] This utility model provides a mold processing and fixing device. By fixing multiple spring telescopic rods to a first fixing plate, when the first fixing plate moves to a designated position, the multiple spring telescopic rods fixed to the first fixing plate come into contact with the mold surface, which can clamp and fix irregularly shaped molds, reducing the difficulty of fixing the mold when it is irregularly shaped.
[0014] This utility model provides a mold processing fixing device. Multiple guide blocks are fixedly connected to the first fixing plate, and multiple sliding grooves are opened on the operating table. When the first fixing plate moves, it drives the guide blocks to slide inside the sliding grooves, which can make the movement of the first fixing plate more stable and reduce the shaking of the first fixing plate during use, which may cause the spring telescopic rod to loosen the fixing of the mold.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0025] Please see Figures 1-7As shown, a mold processing fixing device includes an operating table 1. A pair of first linear motors 11 are fixedly connected to the operating table 1. A first slider 12 is fixedly connected to the output end of the first linear motor 11. A support column 13 is fixedly connected to the first slider 12. A connecting column 14 is fixedly connected between the pair of support columns 13. A second linear motor 15 is fixedly connected to the connecting column 14. A second slider 16 is fixedly connected to the output end of the second linear motor 15. A grinding tool 17 is provided on the second slider 16. A pair of fixed seats 18 are fixedly connected to the operating table 1. A hydraulic cylinder 19 is fixedly connected to the fixed seat 18. A first fixing plate 110 is fixedly connected to the output end of the hydraulic cylinder 19. The first fixing plate 110 is a hollow structure. Multiple spring telescopic rods 111 are fixedly connected to the first fixed plate 110. Multiple connecting holes 112 are provided on the first fixed plate 110, and the connecting holes 112 and spring telescopic rods 111 are correspondingly arranged. The spring telescopic rods 111 and the first fixed plate 110 are connected. An air tank 113 is fixedly connected to the hydraulic cylinder 19, and an air pump 114 is installed on the air tank 113. An air supply pipe 115 is connected to the air tank 113, and the air supply pipe 115 is connected to the first fixed plate 110. When the mold needs to be processed, the mold is placed on the operating table 1, and then a pair of hydraulic cylinders 19 are activated. When the pair of hydraulic cylinders 19 are activated, they drive the first fixed plate 110 to move towards the center of the operating table 1. When the first fixed plate 110 moves to the designated position... When the mold is in place, multiple spring telescopic rods 111 fixed to the first fixed plate 110 are in contact with the mold surface. When the mold is irregularly shaped, the protruding points on the mold contact the spring telescopic rods 111. At this time, the spring telescopic rods 111 are compressed towards the hydraulic cylinder 19, so that the spring telescopic rods 111 can make closer contact with the mold surface to fix the mold. During fixing, the air pump 114 is turned on to send the gas inside the air tank 113 into the first fixed plate 110 through the air pipe 115. The gas enters the first fixed plate 110 through multiple connecting holes 112. When the gas enters the first fixed plate 110, the gas pushes up the uncompressed spring telescopic rods 111. The pushed-up spring telescopic rods 111 then... The mold is limited on both sides to reduce the retraction of spring telescopic rods 111 that are not fully compressed during processing, thus preventing lateral movement of the mold body. After fixing, the first linear motor 11 and the second linear motor 15 are activated to adjust the position of the grinding tool 17. After adjustment, the grinding tool 17 is activated to process the mold. After processing, the hydraulic cylinder 19 is operated to move the first fixed plate 110 away from the center of the operating table 1 to release the mold from fixation. Because multiple spring telescopic rods 111 are fixed on the first fixed plate 110, when the first fixed plate 110 moves to the designated position, the multiple spring telescopic rods 111 fixed on the first fixed plate 110 contact the mold surface, which can clamp and fix irregularly shaped molds.This reduces the difficulty in securing the mold when it has an irregular shape.
[0026] Please see Figure 3 As shown, the operating table 1 has multiple sliding grooves 2, and the first fixed plate 110 has multiple guide blocks 21 fixedly connected to it. The sliding grooves 2 and guide blocks 21 are arranged correspondingly. When the hydraulic cylinder 19 is turned on, it drives the first fixed plate 110 to move. When the first fixed plate 110 moves, it drives the guide blocks 21 to slide inside the sliding grooves 2. By fixing multiple guide blocks 21 to the first fixed plate 110 and opening multiple sliding grooves 2 on the operating table 1, the first fixed plate 110 can move more stably, reducing the shaking of the first fixed plate 110 during use and preventing the spring telescopic rod 111 from loosening its fixation on the mold.
[0027] Please see Figures 3 to 6 As shown, multiple second fixing plates 3 are fixedly connected to the operating table 1, and multiple third fixing plates 31 are fixedly connected to the first fixing plate 110. Multiple sets of guide strips 32 are fixedly connected to the operating table 1. The third fixing plates 31 and guide strips 32 are in sliding fit. The slide groove 2 is located between a set of guide strips 32. An elastic cloth 33 is fixedly connected between the second fixing plates 3 and the third fixing plates 31. When the first fixing plate 110 moves, it drives the third fixing plate 31 to move. When the third fixing plate 31 moves, it drives the elastic cloth 33 to move accordingly. When the mold is fixed at the designated position, the third fixing plate 31 also moves to the designated position. At this time, the elastic cloth 33 fixed between the second fixing plate 3 and the third fixing plate 31 is stretched. The stretched elastic cloth 33 covers the slide groove 2. By fixing the elastic cloth 33 between the second fixing plate 3 and the third fixing plate 31, when the elastic cloth 33 is stretched, it covers the slide groove 2, which can reduce the falling of debris and impurities generated during the processing of the mold into the slide groove 2, thus preventing the slide groove 2 from moving and getting stuck inside the guide block 21.
[0028] Please see Figure 4 As shown, multiple balls 4 are rotatably connected to the guide block 21. The balls 4 are arranged in an array and are located between the guide block 21 and the slide groove 2. When the hydraulic cylinder 19 is activated, it drives the first fixed plate 110 to move. When the first fixed plate 110 moves, it drives the guide block 21 to move accordingly. When the guide block 21 moves, the balls 4 come into contact with the inner wall of the slide groove 2. At this time, the balls 4 roll on the inner wall of the guide block 21. By rotatably connecting multiple balls 4 to the guide block 21, the balls 4 roll on the inner wall of the slide groove 2 when the guide block 21 moves in the slide groove 2, which makes the guide block 21 move more smoothly inside the slide groove 2 and reduces the possibility of the guide block 21 not moving smoothly inside the slide groove 2.
[0029] Please see Figure 5 As shown, a connecting seat 5 is fixedly connected to the end of the spring telescopic rod 111. A slot 51 is provided on the connecting seat 5. A pressing block 52 is rotatably connected in the slot 51. When the spring telescopic rod 111 moves to the designated position, the pressing block 52 contacts the mold surface. When the mold is irregularly shaped, the angle of the pressing block 52 changes. At this time, the pressing block 52 fits the mold surface better. By rotatably connecting the pressing block 52 in the slot 51, the situation where the angle of the spring telescopic rod 111 cannot be adjusted and cannot fit the mold surface better during use can be reduced.
[0030] Please see Figures 5 to 6 As shown, a rubber block 6 is fixedly attached to the pressing block 52. The rubber block 6 is made of flexible material. When the pressing block 52 moves to the designated position to fix the mold, the rubber block 6 contacts the mold surface to fix the mold. By fixing the rubber block 6 to the pressing block 52, the friction between the pressing block 52 and the mold surface can be increased, reducing the situation where the mold shakes due to insufficient friction during use. At the same time, it can reduce the situation where the pressing block 52 directly contacts the mold surface during use, causing scratches on the mold surface.
[0031] Working principle: When the mold needs to be processed, the mold is placed on the operating table 1, and then a pair of hydraulic cylinders 19 are activated. When the pair of hydraulic cylinders 19 are activated, they drive the first fixed plate 110 to move towards the center of the operating table 1. When the first fixed plate 110 moves to the designated position, the multiple spring telescopic rods 111 fixed on the first fixed plate 110 contact the mold surface. When the mold is irregularly shaped, the protruding points on the mold contact the spring telescopic rods 111. At this time, the spring telescopic rods 111 are compressed towards the hydraulic cylinders 19, so that the spring telescopic rods 111 can make closer contact with the mold surface to fix the mold. During fixing, the air pump 114 is activated to fill the air tank 113. The internal gas is supplied to the first fixed plate 110 through the gas supply pipe 115. The gas enters the first fixed plate 110 through multiple connecting holes 112. When the gas enters the first fixed plate 110, it pushes up the uncompressed spring telescopic rod 111. The pushed-up spring telescopic rod 111 limits the left and right sides of the mold, thereby reducing the phenomenon of the spring telescopic rod 111 retracting if it is not fully compressed during processing, which would cause the mold body to move laterally. After fixing, the first linear motor 11 and the second linear motor 15 are turned on to adjust the position of the grinding tool 17. After adjustment, the grinding tool 17 is turned on. The cutting tool 17 processes the mold. After processing, the hydraulic cylinder 19 is operated to move the first fixed plate 110 away from the center of the operating table 1 to release the mold from its fixation. When the hydraulic cylinder 19 is activated, it moves the first fixed plate 110. When the first fixed plate 110 moves, it moves the guide block 21 to slide inside the slide groove 2. When the first fixed plate 110 moves, it moves the third fixed plate 31. When the third fixed plate 31 moves, it moves the elastic cloth 33. When the first fixed plate 110 moves to the designated position to fix the mold, the third fixed plate 31 also moves to the designated position. At this time, the elastic cloth 33 fixed between the second fixed plate 3 and the third fixed plate 31 is... The stretched elastic cloth 33 covers the slide groove 2. When the hydraulic cylinder 19 is turned on, it drives the first fixed plate 110 to move. When the first fixed plate 110 moves, it drives the guide block 21 to move accordingly. When the guide block 21 moves, the ball 4 contacts the inner wall of the slide groove 2. At this time, the ball 4 rolls on the inner wall of the guide block 21. When the spring telescopic rod 111 moves to the designated position, the pressing block 52 contacts the mold surface. When the mold is irregular in shape, the angle of the pressing block 52 changes. At this time, the pressing block 52 fits the mold surface better. When the pressing block 52 moves to the designated position to fix the mold, the rubber block 6 contacts the mold surface to fix the mold.
