Description

Technical Field

[0001] This utility model relates to the field of mold locking device technology, specifically a hydraulic mold locking machine quick-adjustment mechanism that adapts to mold thickness. Background Technology

[0002] Mold locking devices are key components used to fix molds and prevent them from shifting due to pressure or vibration during molding processes such as injection molding, die casting, and stamping. The locking device moves to the sides or top of the mold via guide rails or sliders. The hydraulic system drives the piston rod to extend and push the locking block to press the mold. The hydraulic cylinder has a built-in displacement sensor that can adaptively adjust the piston stroke according to the mold thickness to ensure a constant locking force.

[0003] In the existing technology, the movement distance of the locking block at the end of the mold clamping device is limited. If the size of the mold used changes, it is necessary to frequently replace the mold clamping device with a different size. Moreover, the clamping device mainly relies on hydraulic locking and lacks additional locking measures. If the hydraulic system fails, the locking block can easily loosen, affecting stability. Therefore, a hydraulic clamping machine with a quick-adjustment mechanism that adapts to the mold thickness is needed to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to provide a quick-adjustment mechanism for a hydraulic clamping machine that adapts to the thickness of the mold, in order to solve the problems mentioned in the background art, such as the limited movement distance of the locking block at the end of the mold clamping device, the need to frequently replace the clamping device of different sizes if the size of the mold used changes, the lack of additional locking measures, and the easy loosening of the locking block if the hydraulic system fails.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid adjustment mechanism for a hydraulic mold clamping machine that adapts to mold thickness, comprising a hydraulic mold clamping device, a mold pressing rod rotatably mounted on the hydraulic mold clamping device, a hydraulic cylinder being provided inside the hydraulic mold clamping device, the telescopic end of the hydraulic cylinder being movably mounted on the mold pressing rod; a movable pressure rod being slidably mounted inside the mold pressing rod, an adjustment structure being connected to the movable pressure rod, two threaded seats being symmetrically mounted on the mold pressing rod, each of the two threaded seats being connected to a limit structure, a U-shaped frame being slidably mounted on the hydraulic mold clamping device, and a support structure being connected to the U-shaped frame.

[0006] Preferably, the adjustment structure includes a limiting block, which is slidably installed inside the movable pressure rod and mounted on the pressure rod. A fixing screw is slidably installed inside the limiting block, with its two ends respectively installed on the inner walls of both sides of the movable pressure rod. Two limiting nuts are threaded onto the fixing screw, and the two limiting nuts respectively contact the two sides of the limiting block.

[0007] Preferably, the mold rod has a guide hole inside, and the movable mold rod is slidably installed inside the guide hole.

[0008] Preferably, the limiting structure includes a pressing screw, which is threaded inside the threaded seat, and a rubber pad is installed at one end of the pressing screw, with the rubber pad in contact with the surface of the movable pressure rod.

[0009] Preferably, several limiting grooves are provided on both sides of the movable pressure rod.

[0010] Preferably, the support structure includes two support blocks, both of which are installed above the U-shaped frame, and trapezoidal blocks are installed on both sides of the molding rod, with the two trapezoidal blocks respectively contacting the two support blocks.

[0011] Preferably, a limit screw is installed on one side of the hydraulic clamping device. The limit screw is slidably installed inside the U-shaped frame. A threaded sleeve is threaded on the limit screw, and a linkage gear ring is fixedly fitted on the threaded sleeve. A reduction motor is installed above the U-shaped frame. A linkage gear is installed at the output end of the reduction motor. The linkage gear meshes with the linkage gear ring. A limit collar is rotatably fitted on the threaded sleeve, and the limit collar is installed on one side of the U-shaped frame.

[0012] Preferably, the U-shaped frame has two guide grooves inside, and guide bars are slidably installed in both guide grooves. The two guide bars are respectively installed on both sides of the hydraulic clamping device.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, the pressure rod can be flipped by driving the hydraulic cylinder, which in turn drives the movable pressure rod to press on the bottom plate of the mold for locking and fixing. By rotating the limit nut, it can be moved on the fixed screw and separated from the limit block. At this time, the movable pressure rod can be pushed and pulled to adjust the distance between it and the mold, so that the movable pressure rod can be used for locking molds of different thicknesses, avoiding the frequent replacement of the clamping device due to changes in mold size. Furthermore, by rotating the pressure screws on both sides, the rubber pad can be driven to clamp on the movable pressure rod, further increasing the stability of the movable pressure rod.

[0015] (2) While the pressure rod flips and locks the mold, it will drive the trapezoidal block to flip as well. At this time, the deceleration motor can be turned on to drive the U-shaped frame to move horizontally, thereby driving the support block to move to the bottom of the trapezoidal block and contact the inclined surface of the trapezoidal block, providing auxiliary support for the pressure rod. When the hydraulic system fails, the pressure rod can be prevented from directly loosening under the auxiliary support of the support block. Attached Figure Description

Detailed Implementation

[0021] 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 protection scope of the present utility model.

[0022] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a rapid adjustment mechanism for a hydraulic clamping machine that adapts to mold thickness, including a hydraulic clamping device 100, a clamping rod 101 rotatably mounted on the hydraulic clamping device 100, a hydraulic cylinder 102 internally disposed in the hydraulic clamping device 100, the telescopic end of the hydraulic cylinder 102 being movably mounted on the clamping rod 101; a movable clamping rod 200 slidably mounted inside the clamping rod 101, an adjustment structure connected to the movable clamping rod 200, the adjustment structure being used to adjust the position of the movable clamping rod 200 to adapt to molds of different thicknesses, two threaded seats 300 symmetrically mounted on the clamping rod 101, each threaded seat 300 having a limit structure connected inside, the limit structure being used to limit and fix the adjustment of the movable clamping rod 200, a U-shaped frame 400 slidably mounted on the hydraulic clamping device 100, a support structure connected to the U-shaped frame 400, the support structure being used to support the clamping rod 101, and to provide additional support for the clamping rod 101 in the event of hydraulic failure.

[0023] Furthermore, the adjustment structure includes a limiting block 201, which is slidably installed inside the movable pressure rod 200. The limiting block 201 is mounted on the pressure rod 101. A fixing screw 202 is slidably installed inside the limiting block 201. The two ends of the fixing screw 202 are respectively installed on the inner walls of the two sides of the movable pressure rod 200. Two limiting nuts 203 are threaded on the fixing screw 202. The two limiting nuts 203 are in contact with the two sides of the limiting block 201. By controlling the extension and retraction of the output end of the hydraulic cylinder 102, the pressure rod 101 can be rotated, causing the end of the movable pressure rod 200 to press against the mold. By rotating the limiting nuts 203, they can be moved on the fixing screw 202, causing the limiting nuts 203 to disengage from the limiting block 201, thus releasing the restriction on the movable pressure rod 200.

[0024] Furthermore, the mold rod 101 has a guide sliding hole 204 inside, and the movable pressure rod 200 is slidably installed inside the guide sliding hole 204. When the movable pressure rod 200 moves, it can slide in the guide sliding hole 204. The direction of movement of the movable pressure rod 200 can be restricted by the setting of the guide sliding hole 204.

[0025] Furthermore, the limiting structure includes a pressing screw 301, which is threadedly installed inside the threaded seat 300. A rubber pad 302 is installed at one end of the pressing screw 301, and the rubber pad 302 contacts the surface of the movable pressure rod 200. When the pressing screws 301 on both sides are rotated, the pressing screws 301 can drive the rubber pad to press against the surface of the movable pressure rod 200 through the threaded engagement with the threaded seat 300.

[0026] Furthermore, several limiting grooves 303 are provided on both sides of the movable pressure rod 200. When squeezed, the rubber pad 302 will be slightly deformed, pressing part of the rubber pad 302 into the limiting groove 303, increasing the friction between it and the movable pressure rod 200.

[0027] Example 2: Figure 1-4To further improve the stability of the compression molding rod 101 and prevent it from loosening in case of hydraulic failure, a support structure is provided. This support structure includes two support blocks 401, both mounted above the U-shaped frame 400. Trapezoidal blocks 402 are installed on both sides of the compression molding rod 101, contacting the two support blocks 401 respectively. A limit screw 403 is installed on one side of the hydraulic clamping device 100, and the limit screw 403 slides... Inside the U-shaped frame 400, a threaded sleeve 404 is threaded onto the limiting screw 403, and a linkage gear ring 405 is fixedly fitted onto the threaded sleeve 404. A reduction motor 406 is mounted above the U-shaped frame 400, and a linkage gear 407 is mounted at the output end of the reduction motor 406. The linkage gear 407 meshes with the linkage gear ring 405. A limiting collar 408 is rotatably fitted onto the threaded sleeve 404, and the limiting collar 408 is installed on one side of the U-shaped frame 400. (The last sentence appears to be incomplete and possibly refers to a different component, "the pressure molding rod..."). While the mold is flipped and fixed, the trapezoidal block 402 will also flip. During this process, the reduction motor 406 can be turned on to drive the linkage gear 407 to rotate. When the linkage gear 407 rotates, it can drive the threaded sleeve 404 to rotate through the meshing with the linkage gear ring 405. The continuously rotating threaded sleeve 404 can drive the U-shaped frame 400 to slide through the threaded engagement with the limit screw 403. The continuously moving U-shaped frame 400 can drive the support block 401 to support under the inclined surface of the trapezoidal block 402. The U-shaped frame 400 has two guide grooves 409 inside. Guide bars 410 are slidably installed in both guide grooves 409. The two guide bars 410 are respectively installed on both sides of the hydraulic mold clamp 100. The sliding U-shaped frame 400 can slide on the two guide bars 410 through the two guide grooves 409 respectively. The movement direction of the U-shaped frame 400 can be restricted by the setting of the guide grooves 409 and the guide bars 410. The remaining features are the same as in embodiment 1.

[0028] The working principle is as follows: During use, controlling the extension and retraction of the output end of the hydraulic cylinder 102 can drive the pressure rod 101 to rotate. The rotated pressure rod 101 can drive the end of the movable pressure rod 200 to clamp onto the mold base plate, locking the mold. By rotating the limit nut 203, it can be moved through the threaded engagement with the fixed screw 202, causing the limit nut 203 to disengage from the limit block 201. At this time, the restriction on the movable pressure rod 200 can be released. By pushing the movable pressure rod 200, it can slide within the guide sliding hole 204. The distance between the movable pressure rod 200 and the mold can be adjusted according to the mold thickness, so that the movable pressure rod 200... It can fix molds of different thicknesses. After adjustment, the two limit nuts 203 can be rotated in the opposite direction to press them back onto the limit block 201, thus re-limiting the position of the movable pressure rod 200 and completing the adjustment operation. Then, the abutment screws 301 on both sides are rotated. When the abutment screws 301 rotate, they can drive the rubber pad 302 to move through the thread engagement with the threaded seat 300. The rubber pad 302 can be pressed tightly onto the surface of the movable pressure rod 200. When squeezed, the rubber pad 302 will be slightly deformed, pressing part of the rubber pad 302 into the limit groove 303, increasing the friction between it and the movable pressure rod 200, and improving the stability of the movable pressure rod 200.

[0029] While the pressing rod 101 flips and fixes the mold, it will cause the trapezoidal block 402 to flip as well, causing the angle of the inclined surface of the trapezoidal block 402 to change. During the process, the reduction motor 406 can be turned on to drive the linkage gear 407 to rotate. When the linkage gear 407 rotates, it can drive the threaded sleeve 404 to rotate through the meshing with the linkage gear ring 405. The threaded sleeve 404 will rotate within the limiting collar 408. The limiting collar 408 can prevent the threaded sleeve 404 from coming loose from one side of the U-shaped frame 400. The continuously rotating threaded sleeve 404 can move through the threaded engagement with the limiting screw 403, so that the threaded sleeve 404 can drive the U-shaped frame 400 to slide. The continuously moving U-shaped frame 400 can drive the support block 401 to support the inclined surface of the trapezoidal block 402. The moving distance of the support block 401 can be adjusted according to the degree of flipping of the pressing rod 101, so that the support block 401 can provide additional support for the trapezoidal block 402 and the pressing rod 101.
