Description

Technical Field

[0001] The utility model relates to the technical field of vulcanizers, in particular to a vulcanization device for heat-conducting silica gel sheets. Background Technique

[0002] A heat-conducting silica gel sheet is a heat-conducting medium material synthesized by a special process with silica gel as the base material and adding various auxiliary materials such as metal oxides. It can fill gaps, complete heat transfer between the heat-generating part and the heat-dissipating part, and at the same time play roles such as insulation, shock absorption, and sealing. During the production process of heat-conducting silica gel sheets, a vulcanizer is required for processing. A vulcanizer is a machine for vulcanizing various rubber and plastic products, with functions such as timing mold clamping, automatic pressure compensation, automatic temperature control, and automatic timing and alarm when the time is up.

[0003] A vertical vulcanization and forming device for heat-conducting silica gel sheets provided by the publication number "CN219618288U" shows that this patented technology can rotate the mold through the rotation of the placement plate so that it can accurately complete the stamping process, reduce the stamping error caused by the offset of the mold position, and thus reduce the risk brought by manually moving the mold.

[0004] However, the following problems still exist in the implementation of the above device:

[0005] For example, after the vulcanization process of this device, the mold will be in a high-temperature state at this time. The heat-conducting silica gel sheet that has been vulcanized may stick to the mold. If the staff directly takes the material, there is a risk of scalding the staff. If the material is taken after waiting for the mold to cool down, the work efficiency will be seriously affected. Content of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Example 1, please refer to Figures 1-4 , the present utility model provides a technical solution:

[0026] A vulcanization device for a heat-conducting silica gel sheet, including a connecting seat 1, the inner wall of the connecting seat 1 is fixedly connected with a limiting plate 2, and a downward pressing die mechanism 3 is arranged on the outer wall of the limiting plate 2, and an elastic material feeding mechanism 4 is arranged inside the downward pressing die mechanism 3. Further, the downward pressing die mechanism 3 includes a downward pressing die 301, and a first chute 302 is opened on the side wall of the downward pressing die 301. A second chute 303 is penetrated through the inner wall of the first chute 302, and a slide block 304 is fixedly connected to the side wall of the second chute 303. A processing area 305 is opened on the top of the downward pressing die 301, and a plurality of through holes 306 are penetrated through the bottom of the processing area 305. The inner walls of the plurality of through holes 306 are communicated with the second chute 303, and a threaded through hole 307 is penetrated through the side wall of the downward pressing die 301;

[0027] More specifically, in this embodiment, first place the product to be processed on the processing area 305, and then drive the hydraulic press 10 to press down the upper pressing die 8 so that the pressing surface of the upper pressing die 8 is closed with the processing area 305, and then carry out the vulcanization work;

[0028] After the vulcanization process is completed and it is necessary to take out the vulcanized thermal conductive silicone sheet, first, the hydraulic press 10 is driven to lift the upper pressing die 8, and then the driving motor 5 drives the threaded rod 6 to rotate. Since the lower pressing die mechanism 3 is threadedly connected to the outer wall of the threaded rod 6 through the threaded through hole 307, when the threaded rod 6 rotates, it will drive the lower pressing die mechanism 3 to move outward. Then, the first chute 302 will slide along the outer wall of the limiting plate 2. After the lower pressing die mechanism 3 slides to a certain position, at this time, the sliding plate 401 inside the lower pressing die mechanism 3 will contact the inclined surface of the limiting plate 2. After further sliding, at this time, the sliding plate 401 will be lifted inside the second chute 303 through the inclined surface. At the same time, the sliding plate 401 will slide to the top of the limiting plate 2. During the lifting process of the sliding plate 401, the sliding column 402 is simultaneously driven to slide upward on the inner wall of the through hole 306, and then the convex block 404 will protrude above the surface of the processing area 305, so as to push out the bottom of the vulcanized thermal conductive silicone sheet, so that it will not adhere to the surface of the processing area 305. After the lower pressing die mechanism 3 is completely removed, at this time, the staff can directly take the material to avoid the risk of being scalded.

[0029] Embodiment 2, on the basis of the above embodiment, the elastic material mechanism 4 includes a sliding plate 401, and a plurality of sliding columns 402 are fixedly connected to the top of the sliding plate 401. A convex block 404 is fixedly connected to the top of the plurality of sliding columns 402. A spring 403 is fixedly connected to the position corresponding to the sliding column 402 on the top of the sliding plate 401, and a third chute 405 is opened on the side wall of the sliding plate 401;

[0030] Further, the inner wall of the first chute 302 is slidably connected to the outer wall of the limiting plate 2, the outer wall of the slider 304 is slidably connected to the inner wall of the third chute 405, the outer wall of the sliding column 402 is slidably connected to the inner wall of the through hole 306, one end of the spring 403 away from the sliding plate 401 is fixedly connected to the top of the second chute 303, a motor 5 is fixedly installed on the side wall of the connecting seat 1, and an output shaft of the motor 5 is fixedly connected to a threaded rod 6. The end of the threaded rod 6 away from the motor 5 is rotatably connected to the inner wall of the connecting seat 1, and the outer wall of the threaded rod 6 is threadedly connected to the inner wall of the threaded through hole 307;

[0031] More specifically, in this embodiment, after the material taking is completed, the driving motor 5 rotates reversely to make the downward pressing die mechanism 3 move for reset. When the sliding plate 401 passes through the inclined surface of the limiting plate 2, the sliding plate 401 will slide along the inclined surface of the limiting plate 2 and at the same time move downward for reset, thereby driving the convex block 404 to move downward. After the sliding plate 401 and the limiting plate 2 are separated and no longer in contact, at the same time, the spring 403 will squeeze the sliding plate 401 to make the sliding plate 401 slide to the bottom of the second sliding groove 303. At this time, the elastic material mechanism 4 is reset, and at the same time, the top of the convex block 404 is at the same height as the surface of the processing area 305, so as not to delay the next vulcanization work. Then, the downward pressing die mechanism 3 moves to a position corresponding to the lower part of the upper pressing die 8, and the reset process can be completed. The above process is simple in operation and effectively improves the work efficiency.

[0032] Working principle: First, place the product to be processed on the processing area 305, then drive the hydraulic press 10 to press down the upper pressing die 8, and then carry out the vulcanization work. After the vulcanization process is completed and the vulcanized heat-conducting silica gel sheet needs to be taken out, first drive the hydraulic press 10 to lift the upper pressing die 8, and then drive the motor 5 to drive the threaded rod 6 to rotate. When the threaded rod 6 rotates, it will drive the downward pressing die mechanism 3 to move outward. After the downward pressing die mechanism 3 moves to a certain position, at this time, the sliding plate 401 inside the downward pressing die mechanism 3 will contact the inclined surface of the limiting plate 2. When sliding further, the sliding plate 401 will be lifted inside the second sliding groove 303 through the inclined surface, and at the same time, the sliding plate 401 will slide to the top of the limiting plate 2. During the lifting process of the sliding plate 401, the sliding column 402 is driven to slide upward along the inner wall of the through hole 306 at the same time, and then the convex block 404 will protrude above the surface of the processing area 305, so as to push out the bottom of the vulcanized heat-conducting silica gel sheet and prevent it from sticking to the surface of the processing area 305. After the downward pressing die mechanism 3 is completely moved out, at this time, the staff can directly take the material without the risk of being scalded.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
