Description

Technical Field

[0001] The utility model relates to the technical field of locking devices, in particular to a locking device for a mold frame. Background Art

[0002] A locking device is a device used to fix the mold in mold manufacturing production. It has a simple structure, is easy to operate, and is cheap. The device can not only effectively fix the mold, but also avoid damage to the mold body caused by long-term production, thereby extending the service life of the mold and reducing production costs. Announcement No.: CN220517396U discloses a mold locking device, including a support frame and a locking mechanism installed above the support frame. The locking mechanism includes a locking assembly and a replacement assembly. The locking assembly includes a support plate, a first slide rail, a first slider, a threaded bolt, a first handle, a first rotating shaft, a first movable plate, a second rotating shaft, a hand-controlled frame, a third rotating shaft, a fourth rotating shaft, and a second movable plate; the mold locking device is provided with a hand-controlled frame, and the hand-controlled frame is controlled by external force. The manual control frame can be moved back and forth, and moving the manual control frame will make the first movable plate move, and finally control the first slider to slide back and forth. A mold shell is provided at one end of the first slider, and the mold is placed on the placement plate, and the mold can be clamped and locked by the mold shells on both sides. In this way, when dealing with different molds, it can be controlled by manual external force to make it clamped just right, avoiding damage to the mold due to inappropriate locking. However, the above-mentioned utility model needs to turn the handle to re-lock each time the mold is fixed, and each re-locking takes a certain amount of time, which undoubtedly increases the workload of the operator and reduces the production efficiency, and needs to be improved. Utility Model Content

[0003] The purpose of the utility model is to solve the technical problems raised in the above background technology.

[0004] The utility model adopts the following technical scheme: a locking device for a mold frame, comprising a base, a support base is fixedly installed on the surface of the base, a triangular block is fixedly installed on the surface of the support base, a cross bar is rotatably connected to the surface of the triangular block, a first rotating shaft is rotatably connected to the inside of the triangular block, an inclined rod is fixedly installed on the side of the cross bar, an arc-shaped connecting block is rotatably connected to the surface of the cross bar, a second rotating shaft and a third rotating shaft are rotatably connected to the inside of the arc-shaped connecting block, a telescopic rod is rotatably connected to the surface of the arc-shaped connecting block, a fixed sleeve is slidably connected to the surface of the telescopic rod, a rubber block is fixedly installed on a side of the telescopic rod away from the arc-shaped connecting block, a storage plate is slidably connected to the surface of the base, and a limiting block is fixedly installed on the side of the storage plate.

[0005] Preferably, the number of the triangular blocks is two groups, and the two groups of triangular blocks are symmetrically distributed on both sides of the crossbar, and the first rotating shaft runs through the two groups of triangular blocks and the crossbar. Here, the first rotating shaft runs through the triangular blocks and the crossbar, so that the crossbar rotates on the surface of the first rotating shaft, making the rotation of the crossbar smoother, reducing the resistance generated when using the clamp, and saving the operator's physical strength.

[0006] Preferably, the number of the arc-shaped connecting blocks is two groups, and the two groups of arc-shaped connecting blocks are symmetrically distributed on both sides of the cross bar and the telescopic rod, the second rotating shaft runs through the two groups of arc-shaped connecting blocks and the cross bar, and the third rotating shaft runs through the two groups of arc-shaped connecting blocks and the telescopic rod.

[0007] Preferably, the fixing sleeve is fixed to the support base. Here, the fixing sleeve is fixedly installed to the support base, so that the telescopic rod can only slide inside the fixing sleeve and cannot rotate, thereby improving the stability of the device and preventing the telescopic rod from slipping out during operation and causing damage.

[0008] Preferably, the surface of the inclined rod is covered with a rubber sleeve, and the material of the rubber sleeve is natural rubber.

[0010] Preferably, the slider is fixed to the storage plate, and the slider and the slide groove are both T-shaped. Here, the slider slides inside the slide groove to drive the storage plate and the limit block to move together. After adjusting the position, it is only necessary to readjust the position when changing a different mold, avoiding frequent locking by the operator, reducing the workload of the operator, and improving production efficiency.

Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0021] Embodiment 1

The surface of the base 1 is slidably connected with a fixing sleeve 11, a rubber block 12 is fixedly installed on one side of the telescopic rod 9 away from the arc-shaped connecting block 7, a storage plate 13 is slidably connected to the surface of the base 1, and a limit block 14 is fixedly installed on the side of the storage plate 13. There are two groups of triangular blocks 3, and the two groups of triangular blocks 3 are symmetrically distributed on both sides of the cross bar 4. The first rotating shaft 5 passes through the two groups of triangular blocks 3 and the cross bar 4, and the first rotating shaft 5 passes through the triangular blocks 3 and the cross bar 4, so that the cross bar 4 rotates on the surface of the first rotating shaft 5, so that the rotation of the cross bar 4 is smoother, which reduces the resistance generated when using the clamp, and saves energy. The operator's physical strength is saved. There are two groups of arc-shaped connecting blocks 7, and the two groups of arc-shaped connecting blocks 7 are symmetrically distributed on both sides of the cross bar 4 and the telescopic rod 9. The second rotating shaft 8 runs through the two groups of arc-shaped connecting blocks 7 and the cross bar 4, and the third rotating shaft 10 runs through the two groups of arc-shaped connecting blocks 7 and the telescopic rod 9. The second rotating shaft 8 and the third rotating shaft 10 rotate and connect the cross bar 4, the arc-shaped connecting block 7 and the telescopic rod 9 together. When the staff pulls the diagonal rod 6, the cross bar 4 and the arc-shaped connecting block 7 rotate together, and the telescopic rod 9 slides inside the fixed sleeve 11. The operation is simple and convenient, and no additional operation is required. It greatly saves the operator's physical strength and improves work efficiency. The fixed sleeve 11 is fixed to the support seat 2, and the fixed sleeve 11 and the support seat 2 are fixedly installed, so that the telescopic rod 9 can only slide inside the fixed sleeve 11 and cannot rotate, thereby improving the stability of the device and preventing the telescopic rod 9 from slipping out during work and causing damage. The surface of the inclined rod 6 is provided with a rubber sleeve 15, and the material of the rubber sleeve 15 is natural rubber. The natural rubber material has good elasticity, wear resistance and anti-slip performance. The rubber sleeve 15 can provide a comfortable grip experience and protect the operator's hands from injury.

[0023] Embodiment 2

[0024] See also Figure 3A slide groove 16 is provided on the surface of the base 1, and a threaded rod 18 is rotatably connected inside the slide groove 16. A slider 17 is threadedly connected to the surface of the threaded rod 18, and a knob 19 is fixedly installed on the side of the threaded rod 18 away from the base 1. The movement of the placement plate 13 and the limit block 14 is controlled by setting the threaded rod 18 and the slider 17, so as to control the distance between the rubber block 12 and the limit block 14, so that the device can be suitable for molds of different sizes, thereby improving the applicability of the device. The slider 17 is fixed to the placement plate 13, and the shape of the slider 17 and the slide groove 16 are both T-shaped. The slider 17 is located inside the slide groove 16 and slides to drive the placement plate 13 and the limit block 14 to move together. After adjusting the position, it is only necessary to readjust the position when changing different molds, thereby avoiding frequent locking by operators, reducing the workload of operators, and improving production efficiency.

[0025] Working principle: when debugging the device, first press the inclined rod 6 to the bottom. At this time, the cross bar 4, the arc-shaped limit block 14 and the telescopic rod 9 are all on the same axis, and the cross bar 4, the arc-shaped limit block 14 and the telescopic rod 9 are parallel to the base 1. Then place the mold on the placement plate 13, and then turn the knob 19. The knob 19 drives the threaded rod 18 to rotate, and then the threaded rod 18 drives the slider 17 to move, so that the slider 17 drives the placement plate 13 and the limit block 14 to move toward the direction of the mold. When the limit block 14 and the rubber block 12 lock the mold, you can stop turning the knob 19. At this time, because the cross bar 4, the arc-shaped limit block 14 and the telescopic rod 9 are all on the same axis, and the telescopic rod 9 is restricted by the fixed sleeve 11, only It can move forward and backward. At this time, no matter how much force the rubber clamping block 12 is subjected to, the first rotating shaft 5, the second rotating shaft 8 and the third rotating shaft 10 cannot rotate, and the locking effect is very good. After debugging is completed, pull the inclined rod 6, and the inclined rod 6 gives an upward force to the cross bar 4 and the arc-shaped connecting block 7, so that the cross bar 4 rotates clockwise and the arc-shaped connecting block 7 rotates counterclockwise. At the same time, the arc-shaped connecting block 7 moves upward together with the end connected to the cross bar 4, and the arc-shaped connecting block 7 drives the telescopic rod 9 to move while rotating, so that the rubber clamping block 12 is separated from the mold, and then the mold can be removed. In the subsequent working process, only the inclined rod 6 needs to be pushed to clamp the mold. Only when replacing other types of molds, it is necessary to turn the knob 19 again to adjust the position of the limit block 14.
