Description

Technical Field

[0001] This utility model relates to the field of pin removal for vulcanizing molds, specifically a pin removal device for vulcanizing molds. Background Technology

[0002] In the vulcanization production process of rubber screen plates, the efficient use and maintenance of vulcanization molds are crucial. After vulcanization, disassembling the screen plate mold is a necessary step for the smooth progress of subsequent processes. However, during this process, the disassembly of the pins on the screen plate mold is prone to problems.

[0003] In actual production, when the screen plate vulcanization process ends, the mold and pins are still at a high temperature. At this time, the pins on the screen plate mold often become tightly stuck in the mold due to thermal expansion and rubber residue adhesion, making them impossible to remove. This situation seriously hinders the disassembly process of the screen plate, making it impossible to carry out subsequent quality inspection, cleaning and maintenance of the screen plate in a timely manner, thus affecting the flow efficiency of the entire production line. When the positioning pin is stuck and difficult to remove, the on-site operators often resort to tapping to try to solve the problem. However, this method has significant drawbacks. It is difficult to accurately control the tapping force, and slight carelessness can cause the mold to deform. Once the mold is deformed, the forming accuracy of the screen plate cannot be guaranteed in the subsequent vulcanization process, resulting in a decrease in screen plate quality and an increase in the defect rate. Therefore, it is necessary to design a vulcanization mold pin puller to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a vulcanizing mold pin puller to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pin puller for vulcanizing molds, comprising a pin puller rod, a pad rod welded to the bottom of the pin puller rod, a buckle welded to the left end of the pin puller rod, and a grip sleeve slidably connected to the right side of the surface of the pin puller rod.

[0006] Preferably, a movable groove is provided on the right side of the surface of the pull pin, and a sliding plate is slidably connected inside the movable groove, the surface of the sliding plate being fixedly connected to the inside of the grip sleeve.

[0007] Preferably, a rotating rod is rotatably connected to the right side of the slide plate via a bearing component. The right end of the rotating rod passes through the pull pin and extends to the outside of the pull pin. Limiting blocks are fixedly installed on both the front and rear sides of the rotating rod surface, and several limiting blocks are provided.

[0008] Preferably, the right end of the pull pin has a limiting port that cooperates with the limiting block.

[0009] Preferably, a handle is fixedly installed at the right end of the rotating rod.

[0010] Preferably, magnetic blocks that cooperate with the grip are fixedly installed on both the front and rear sides of the inner cavity of the grip sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This vulcanizing mold pin puller, by setting up a buckle and a pad, allows the device to quickly pull out the fixed pin, which greatly saves the time of screen plate disassembly and ensures the integrity of the screen plate during disassembly. At the same time, by setting up the pin puller, buckle and pad, the contact between personnel and vulcanizing bed is reduced, preventing burns.

[0013] 2. This vulcanizing mold pin puller works by rotating the handle, which in turn drives the rotating rod to rotate. The rotating rod then drives the limiting block to rotate. After the limiting block rotates 90 degrees, the limiting port no longer limits the rotating rod. At this point, the grip can be pulled to the right to adjust the length of the device. After adjusting to the appropriate length, the handle can be reversed 90 degrees. At this point, the limiting block again limits the rotating rod through the limiting port. Furthermore, after the handle rotates, it can limit the rotated rod by attracting the magnetic block, thus achieving the effect of limiting and fixing the adjusted grip. Attached Figure Description

[0020] 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.

[0021] Example 1

[0022] Please refer to Figure 1-5 As shown, this utility model provides a pin puller for vulcanizing molds, including a pin puller 1, a pad 3 welded to the bottom of the pin puller 1, a buckle 2 welded to the left end of the pin puller 1, and a grip sleeve 11 slidably connected to the right side of the surface of the pin puller 1. By setting the buckle 2 and the pad 3, the device can quickly pull off the fixed pins through the buckle 2 and the pad 3, which greatly saves the time of disassembling the screen plate and ensures the integrity of the screen plate during disassembly. At the same time, by setting the pin puller 1, the buckle 2 and the pad 3, the contact between personnel and the vulcanizing bed is reduced, preventing burns.

[0023] Specifically, a movable groove 4 is provided on the right side of the surface of the pin-pulling rod 1. A sliding plate 5 is slidably connected inside the movable groove 4. The surface of the sliding plate 5 is fixedly connected to the inner side of the grip sleeve 11. A rotating rod 6 is rotatably connected to the right side of the sliding plate 5 via a bearing. The right end of the rotating rod 6 passes through the pin-pulling rod 1 and extends to the outside of the pin-pulling rod 1. Limiting blocks 8 are fixedly installed on the front and rear sides of the surface of the rotating rod 6, and several limiting blocks 8 are provided. A limiting port 7 is provided on the right end of the pin-pulling rod 1 to cooperate with the limiting blocks 8. A handle 9 is fixedly installed on the right end of the rotating rod 6. The handle 9 is made of iron metal. A limiter is fixedly installed on the front and rear sides of the inner cavity of the grip sleeve 11. The magnetic block 10, used in conjunction with the grip 9, has a rotating rod 6. By rotating the grip 9, the rotating rod 6 rotates, which in turn rotates the limiting block 8. After the limiting block 8 rotates 90 degrees, the limiting port 7 no longer limits the rotating rod 6. At this point, the grip sleeve 11 can be pulled to the right to adjust the length of the device. After adjusting to the appropriate length, the grip 9 can be reversed 90 degrees. At this point, the limiting block 8 again limits the rotating rod 6 through the limiting port 7. Furthermore, after the grip 9 rotates, it can be attracted to the magnetic block 10 to limit the rotated rotating rod 6, thus achieving the effect of limiting and fixing the adjusted grip sleeve 11.

[0024] Working Principle: This utility model is a pin puller for vulcanizing molds. By setting the buckle 2 and the pad 3, the device can quickly pull out the fixed pins through the buckle 2 and the pad 3, which greatly saves the time of disassembling the screen plate and ensures the integrity of the screen plate during disassembly. At the same time, by setting the pin puller 1, buckle 2 and pad 3, the contact between personnel and vulcanizing bed is reduced, preventing burns. When it is necessary to adjust the length of the device, the handle 9 can be rotated. The rotation of the handle 9 drives the rotating rod 6 to rotate, and the rotation of the rotating rod 6 drives the limiting block 8 to rotate. After the limiting block 8 rotates 90 degrees, the limiting port 7 no longer limits the rotating rod 6. At this time, the grip sleeve 11 can be pulled to the right to achieve the effect of adjusting the length of the device. After adjusting to the appropriate length, the handle 9 can be reversed 90 degrees. At this time, the limiting block 8 limits the rotating rod 6 again through the limiting port 7. After the handle 9 rotates, it can limit the rotated rotating rod 6 by attracting the magnetic block 10, thus achieving the effect of limiting and fixing the adjusted grip sleeve 11.
