Description
Technical Field
[0001] This utility model relates to the field of mold processing technology, and in particular to a mold clamping device for mold processing. Background Technology
[0002] When processing molds, they are typically clamped by a clamping device, and then processed by external equipment. This process generates a large amount of metal shavings, some of which fall into the threaded grooves of the bidirectional lead screw, easily causing wear or even damage to the lead screw. It can also cause jamming of the clamping plate. For example, existing Chinese patents with application numbers 201922103274.4 and 202123444631.7 both exhibit these technical problems. Therefore, the defects are quite obvious, and a solution is urgently needed. Utility Model Content
[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a mold clamping device for mold processing.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A mold clamping device for mold processing includes a base plate, a support mounted on the top surface of the base plate, a T-shaped groove on the support, a support plate located in the middle of the support, the support plate being situated within the T-shaped groove, and two I-shaped sliders slidably connected within the T-shaped groove, the two I-shaped sliders being positioned opposite each other and located on both sides of the support plate. A double-ended lead screw is rotatably connected to the support, the double-ended lead screw being located within the T-shaped groove, the middle portion of the double-ended lead screw rotatably penetrating the support plate, the positive thread section of the double-ended lead screw threaded through one of the I-shaped sliders, and the negative thread section of the double-ended lead screw... The threaded section passes through another I-shaped slider. Each I-shaped slider is equipped with a clamping plate at its top. The positive threaded section of the bidirectional screw is fitted with a positive elastic telescopic sleeve. The two ends of the positive elastic telescopic sleeve are fixedly connected to one side of the support plate and the side of one I-shaped slider, respectively. The negative threaded section of the bidirectional screw is fitted with a rebound telescopic sleeve. The two ends of the rebound telescopic sleeve are fixedly connected to one side of the support plate and the side of another I-shaped slider, respectively. One end of the support is equipped with a rotation driver, which is used to drive the bidirectional screw to rotate.
[0006] Furthermore, the I-shaped slider is provided with a sleeve, and a locking ring is detachably installed on the outside of the sleeve. A two-way screw passes through the sleeve, and the distance between the outer wall of the two-way screw and the inner wall of the sleeve is set. One end of the positive elastic telescopic sleeve or one end of the rebound telescopic sleeve is sleeved on the outside of the sleeve, and the locking ring locks one end of the positive elastic telescopic sleeve or one end of the rebound telescopic sleeve onto the sleeve.
[0007] Furthermore, a cooling mechanism for cooling the I-shaped slider is installed on the outer wall of the clamping plate and / or the top of the I-shaped slider.
[0008] Furthermore, the cooling mechanism includes a cooling water tank disposed within the clamping plate, a first water tank mounted on the I-shaped slider, a water pump mounted on the outer wall of the I-shaped slider or the clamping plate, a first water pipe connected to the outlet of the water pump and the inlet of the cooling water tank, a second water pipe connected to the outlet of the cooling water tank and the inlet of the first water tank, and a third water pipe connected to the outlet of the first water tank and the inlet of the water pump.
[0009] Furthermore, the cooling mechanism also includes a first check valve installed in the first water pipe and a second check valve installed in the second water pipe, with the first check valve and the second check valve having the same flow direction.
[0010] Furthermore, a first heat sink is provided on the outer surface of the first water tank.
[0011] Furthermore, the cooling mechanism also includes a second water tank located in the first water pipe.
[0012] Furthermore, a second heat sink is provided on the outer surface of the second water tank.
[0013] The beneficial effects of this utility model are as follows: In practical applications, the rotary driver drives the bidirectional lead screw to rotate. The positive thread section of the rotating bidirectional lead screw is threadedly connected to one I-shaped slider, and the negative thread section of the rotating bidirectional lead screw is threadedly connected to another I-shaped slider. Because the I-shaped slider is adapted to the concave and convex shape of the T-shaped groove, the I-shaped slider can only move along the T-shaped groove, causing the two I-shaped sliders to move closer to or further away from each other. When the two I-shaped sliders move closer to each other, the two clamping plates clamp the mold; when the two I-shaped sliders move further away from each other, the two clamping plates release the mold. As the two I-shaped sliders approach each other, both the positive elastic telescopic sleeve and the rebound telescopic sleeve are compressed; as the two I-shaped sliders move away from each other, both the positive elastic telescopic sleeve and the rebound telescopic sleeve are stretched. This ensures that the positive thread section of the bidirectional lead screw is always protected by the positive elastic telescopic sleeve, and the negative thread section of the bidirectional lead screw is always protected by the rebound telescopic sleeve. This effectively prevents metal scraps from falling into the thread groove of the bidirectional lead screw, making it less likely to damage the bidirectional lead screw and reducing the problem of jamming during the movement of the two I-shaped sliders.

[0018] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.
[0019] like Figure 1 and Figure 2 As shown, this utility model provides a mold clamping device for mold processing, which includes a base plate 1, a support 2 mounted on the top surface of the base plate 1, a T-shaped groove 3 provided on the support 2, a support plate 4 provided in the middle of the support 2, the support plate 4 located in the T-shaped groove 3, two I-shaped sliders 5 slidably connected in the T-shaped groove 3, the two I-shaped sliders 5 being arranged opposite each other and located on both sides of the support plate 4, a bidirectional lead screw 6 rotatably connected to the support 2, the bidirectional lead screw 6 being located in the T-shaped groove 3, the middle part of the bidirectional lead screw 6 rotatably passing through the support plate 4, the positive thread section of the bidirectional lead screw 6 threaded through one I-shaped slider 5, and the negative thread section of the bidirectional lead screw 6 threaded through the other I-shaped slider 5, each I-shaped slider 5 The top of each component is equipped with a clamping plate 7. The positive thread section of the bidirectional lead screw 6 is fitted with a positive elastic telescopic sleeve 8. The two ends of the positive elastic telescopic sleeve 8 are respectively fixedly connected to one side of the support plate 4 and the side of an I-shaped slider 5. The negative thread section of the bidirectional lead screw 6 is fitted with a rebound telescopic sleeve 9. The two ends of the rebound telescopic sleeve 9 are respectively fixedly connected to one side of the support plate 4 and the side of another I-shaped slider 5. One end of the support 2 is equipped with a rotation driver 10, which is used to drive the bidirectional lead screw 6 to rotate. Specifically, the rotation driver 10 can be a motor. The distance between the positive thread section of the bidirectional lead screw 6 and the positive elastic telescopic sleeve 8 is set, and the distance between the negative thread section of the bidirectional lead screw 6 and the rebound telescopic sleeve 9 is set.
[0020] In practical applications, the rotary actuator 10 drives the bidirectional lead screw 6 to rotate. The positive thread section of the rotating bidirectional lead screw 6 is threadedly connected to one I-shaped slider 5, and the negative thread section of the rotating bidirectional lead screw 6 is threadedly connected to another I-shaped slider 5. Because the I-shaped slider 5 is adapted to the T-shaped groove 3, the I-shaped slider 5 can only move along the T-shaped groove 3, causing the two I-shaped sliders 5 to move closer or further apart. When the two I-shaped sliders 5 move closer together, the two clamping plates 7 clamp the mold; when the two I-shaped sliders 5 move further apart, the two clamping plates 7 release the mold. As the two I-shaped sliders 5 approach each other, both the positive elastic telescopic sleeve 8 and the rebound telescopic sleeve 9 are compressed; as the two I-shaped sliders 5 move away from each other, both the positive elastic telescopic sleeve 8 and the rebound telescopic sleeve 9 are stretched. This ensures that the positive thread section of the bidirectional lead screw 6 is always protected by the positive elastic telescopic sleeve 8, and the negative thread section of the bidirectional lead screw 6 is always protected by the rebound telescopic sleeve 9. This effectively prevents metal scraps from falling into the thread groove of the bidirectional lead screw 6, making it less likely to damage the bidirectional lead screw 6. It also helps to reduce the problem of jamming when the two I-shaped sliders 5 move.
[0021] In this embodiment, the I-shaped slider 5 is provided with a sleeve, and a locking ring 11 is detachably installed on the outside of the sleeve. A bidirectional lead screw 6 passes through the sleeve, and the distance between the outer wall of the bidirectional lead screw 6 and the inner wall of the sleeve is set. One end of the positive elastic telescopic sleeve 8 or one end of the rebound telescopic sleeve 9 is sleeved on the outside of the sleeve, and the locking ring 11 locks one end of the positive elastic telescopic sleeve 8 or one end of the rebound telescopic sleeve 9 onto the sleeve. The other end of the positive elastic telescopic sleeve 8 or the other end of the rebound telescopic sleeve 9 is locked to the support plate 4 by bolts. This structural design facilitates the assembly and disassembly of the positive elastic telescopic sleeve 8 and the rebound telescopic sleeve 9, and ensures the working stability of the positive elastic telescopic sleeve 8 and the rebound telescopic sleeve 9.
[0022] In this embodiment, a cooling mechanism 12 for cooling the I-shaped slider 5 is installed on the outer wall of the clamping plate 7 and / or the top of the I-shaped slider 5. When the mold is clamped by the two clamping plates 7 and the external equipment performs cutting or other processing on the mold, the mold generates heat, which is transferred to the clamping plates 7. The cooling mechanism 12 cools the clamping plates 7 to prevent the clamping plates 7 from deforming due to heat.
[0023] In this embodiment, the cooling mechanism 12 includes a cooling water tank 20 disposed in the clamping plate 7, a first water tank 13 disposed in the I-shaped slider 5, a water pump 14 disposed in the outer wall of the I-shaped slider 5 or the clamping plate 7, a first water pipe 15 connected to the outlet of the water pump 14 and the inlet of the cooling water tank 20, a second water pipe 16 connected to the outlet of the cooling water tank 20 and the inlet of the first water tank 13, and a third water pipe 21 connected to the outlet of the first water tank 13 and the inlet of the water pump 14. In practical applications, initially, both the cooling water tank 20 and the first water tank 13 contain coolant. When the temperature of the coolant in the cooling water tank 20 rises and needs to be replaced, the water pump 14 pumps the coolant from the first water tank 13 into the cooling water tank 20. The coolant in the cooling water tank 20 flows into the first water tank 13, thus replacing the coolant in the cooling water tank 20. At this time, the coolant in the cooling water tank 20 cools the clamping plate 7, while the coolant in the first water tank 13 remains stationary and cools. This structural design facilitates the replacement of the heated coolant in the cooling water tank 20, improving the cooling efficiency of the clamping plate 7.
[0024] In this embodiment, the cooling mechanism 12 further includes a first check valve disposed on the first water pipe 15 and a second check valve disposed on the second water pipe 16, wherein the flow directions of the first check valve and the second check valve are the same. This structural design ensures that the coolant can only flow in one direction, preventing backflow.
[0025] In this embodiment, a first heat sink 17 is provided on the outer surface of the first water tank 13. The first heat sink 17 dissipates heat from the first water tank 13, enabling the coolant inside the first water tank 13 to cool down rapidly.
[0026] In this embodiment, the cooling mechanism 12 further includes a second water tank 18 disposed on the first water pipe 15. Initially, the first water tank 13, the second water tank 18, and the cooling water tank 20 all contain coolant. By adding the second water tank 18, the cooling time of the coolant in the first water tank 13 and the second water tank 18 can be extended during operation.
[0027] In another embodiment, when the water pump 14 is a gear pump, initially, one of the first water tank 13 and the second water tank 18 is empty, and the cooling water tank 20 contains coolant. By controlling the forward and reverse rotation of the gear pump, when the gear pump rotates forward, the coolant in the first water tank 13 flows into the cooling water tank 20, and the coolant in the cooling water tank 20 flows into the second water tank 18. At this time, the first water tank 13 is cooled without load. When it is necessary to replace the coolant in the cooling water tank 20, the gear pump reverses, and the coolant in the cooling water tank 20 flows into the first water tank 13, and the coolant in the second water tank 18 flows into the cooling water tank 20. The second water tank 18 is cooled without load.
[0028] In this embodiment, a second heat sink 19 is provided on the outer surface of the second water tank 18. The second heat sink 19 dissipates heat from the second water tank 18, enabling the coolant inside the second water tank 18 to cool down rapidly.
[0029] All technical features in this embodiment can be freely combined according to actual needs.
[0030] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
