Description

Technical Field

[0001] This utility model relates to the field of mold deformation prevention technology, specifically a molding vulcanization mold deformation prevention device. Background Technology

[0002] In the industrial production of rubber products, vulcanization is a key process that imparts the final properties of the material. Vulcanization molds, under high temperature and high pressure, enable the rubber to obtain the designed shape and physical properties through cross-linking reactions. However, under the influence of long-term cyclic thermal stress, mechanical load and material creep, the molds are prone to local or overall deformation, requiring anti-deformation devices to support the molds.

[0003] A search of Chinese patent CN217252708U reveals a high-performance die-casting mold anti-deformation structure, comprising a base, with first threaded posts symmetrically arranged around the bottom of the base, pressure plates on the outer walls of the first threaded posts, bolts symmetrically threaded around the top of the pressure plates, and limit blocks at the bottom of the bolts. A lower mold is fixedly connected to the center of the top of the base, with cooling water inlets symmetrically opened on the front and back of the lower mold, a fixing post at the top of the cooling water inlets, and a second threaded post fixedly connected to the center of the top of the fixing post. A mold groove is opened in the center of the top of the lower mold, with fitting grooves symmetrically arranged on the left and right sides of the mold groove, and a locking groove at the bottom of the fitting groove. An upper mold is located on the top of the lower mold. This high-performance die-casting mold anti-deformation structure can tightly fit the lower mold and the upper mold together and prevent mold deformation due to shaking.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. The vulcanizing mold is prone to deformation under high temperature and high pressure environment, which makes it difficult to provide anti-deformation support for the mold and also makes it difficult to quickly position and install the mold. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for preventing deformation of molding vulcanizing molds.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a deformation prevention device for a molding vulcanizing mold, including a fixing plate on which a mold body is placed. An deformation prevention mechanism is provided on the fixing plate. The deformation prevention mechanism includes two guide rails symmetrically fixedly installed on the fixing plate. A support component is provided on the inner side of each guide rail. Two support shells are symmetrically and movably installed on the outer side of the mold body. A connecting component adapted to the support component is provided on each support shell. A snap-fit ​​component is provided between the two support shells.

[0008] A cooling mechanism is provided between the fixed plate and the support shell. The cooling mechanism includes a side shell fixedly installed on the support shell, a nozzle fixedly installed on the side shell, and an air supply component adapted to the side shell on the fixed plate.

[0009] Furthermore, the support assembly includes a partition plate fixedly installed inside the guide rail, and two first springs are symmetrically connected to the partition plate, with a slider adapted to the guide rail connected to the end of each first spring.

[0010] Furthermore, the connecting assembly includes two threaded blocks symmetrically fixedly mounted on the support shell, and a fixing bolt that is threadedly connected to the slider is rotatably mounted on the threaded block.

[0011] Furthermore, the snap-fit ​​assembly includes two snap-fit ​​housings symmetrically fixedly mounted on one of the support housings.

[0012] Furthermore, the snap-fit ​​assembly also includes two fixed shells fixedly mounted on another support shell. Each fixed shell has two snap blocks symmetrically and movably mounted on its inner side, which are adapted to the snap-fit ​​shell. The two snap blocks are connected together by two second springs, and each snap block has a side block fixedly mounted on it.

[0013] Furthermore, each of the side shells has two side openings symmetrically fixedly installed.

[0014] Furthermore, the air supply assembly includes two air collection shells symmetrically fixedly mounted on the fixed plate. Each air collection shell is fixedly mounted with an external interface and two connecting interfaces. Each connecting interface is threaded with a threaded sleeve that is compatible with the side opening.

[0015] The above-described solution of this utility model has at least the following beneficial effects:

[0016] 1. In this utility model, by moving the mold body between two support shells and bringing the two support shells close to each other, the two support shells are fixed together by using a locking block and a locking shell. This allows the support shells to provide anti-deformation support for the mold body, and at the same time, it enables the mold body to be quickly positioned and installed.

[0017] 2. In this utility model, by unscrewing the fixing bolt out of the inner side of the slider, the support shell can be disassembled, which facilitates the replacement of the support shell for different mold bodies.

[0018] 3. In this utility model, by screwing the threaded sleeve, the threaded sleeve moves between the interface and the side opening under the thread support of the interface, thereby further fixing the support shell. The external blowing device is connected through the external interface, and the external blowing device is controlled to deliver air to the inside of the air collecting shell. The air inside the air collecting shell moves into the inside of the side shell through the interface and the side opening, and is finally sprayed out from the nozzle to perform air cooling and cooling of the mold body, thereby preventing deformation caused by excessive temperature.

Detailed Implementation

[0026] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0027] like Figures 1 to 5As shown, an embodiment of this utility model provides a deformation prevention device for a molding vulcanizing mold, including a fixed plate 1, on which a mold body 2 is placed. An deformation prevention mechanism is provided on the fixed plate 1, comprising two guide rails 3 symmetrically fixedly mounted on the fixed plate 1. Each guide rail 3 has a support component on its inner side. Two support shells 7 are symmetrically and movably mounted on the outer side of the mold body 2. Each support shell 7 has a connecting component adapted to the support component. A snap-fit ​​component is provided between the two support shells 7. The support component includes a partition plate 4 fixedly mounted on the inner side of the guide rails 3, and two first springs 5 ​​symmetrically connected to the partition plate 4. Each first spring 5 has a slider 6 that is adapted to the guide rail 3 connected to its end. The connecting assembly includes two threaded blocks 8 that are symmetrically fixed on the support shell 7. A fixing bolt 9 that is threadedly connected to the slider 6 is rotatably installed on the threaded block 8. The snap-fit ​​assembly includes two snap-fit ​​shells 10 that are symmetrically fixed on one support shell 7. The snap-fit ​​assembly also includes two fixing shells 11 that are fixed on the other support shell 7. Two snap blocks 13 that are adapted to the snap blocks 10 are symmetrically and movably installed on the inner side of each fixing shell 11. Two second springs 12 are connected between the two snap blocks 13. A side block 14 is fixedly installed on each snap block 13.

[0028] In this embodiment of the utility model, the operator moves the mold body 2 between the two support shells 7, bringing the two support shells 7 closer to each other. The support shells 7 drive the slider 6 to move along the inner side of the guide rail 3 through the threaded block 8 and the fixing bolt 9. The second spring 12 can support the locking block 13 with its own elasticity. The locking block 13 and the locking shell 10 are engaged to fix the two support shells 7 together. Thus, the support shells 7 can be used to support the mold body 2 against deformation. At the same time, the mold body 2 can be quickly positioned and installed.

[0029] When disassembling the mold body 2, the operator presses the side block 14, causing the side block 14 to move the locking block 13, so that the locking block 13 no longer locks the locking shell 10. This allows the first spring 5 to use its own elasticity to move the support shell 7 through the slider 6, the fixing bolt 9, and the threaded block 8, separating the support shell 7 from the mold body 2. Releasing the side block 14 allows the second spring 12 to move the locking block 13 back to its original position, thus facilitating the disassembly of the mold body 2. By unscrewing the fixing bolt 9 from the inside of the slider 6, the support shell 7 can be disassembled, making it easy to replace the support shell 7 for different mold bodies 2.

[0030] Figures 1 to 5As shown, a cooling mechanism is provided between the fixed plate 1 and the support shell 7. The cooling mechanism includes a side shell 15 fixedly installed on the support shell 7. A nozzle 21 is fixedly installed on the side shell 15. An air supply assembly adapted to the side shell 15 is provided on the fixed plate 1. Two side ports 16 are symmetrically fixedly installed on each side shell 15. The air supply assembly includes two air collecting shells 17 symmetrically fixedly installed on the fixed plate 1. An external interface 18 and two connecting interfaces 19 are fixedly installed on each air collecting shell 17. A threaded sleeve 20 adapted to the side port 16 is threadedly installed on each connecting interface 19.

[0031] In this embodiment of the utility model, the external interface 18 is connected to an external blowing device. The operator can move the threaded sleeve 20 between the interface 19 and the side opening 16 by turning the threaded sleeve 20 under the thread support of the interface 19, thereby further fixing the support shell 7. The external blowing device is connected through the external interface 18, and the external blowing device is controlled to deliver air to the inside of the air collecting shell 17. The air inside the air collecting shell 17 moves into the inside of the side shell 15 through the interface 19 and the side opening 16, and is finally sprayed out by the nozzle 21 to perform air cooling and cooling of the mold body 2, thereby preventing deformation caused by excessive temperature.

[0032] Working principle: The operator moves the mold body 2 between the two support shells 7, bringing the two support shells 7 close to each other, and uses the locking block 13 and the locking shell 10 to lock the two support shells 7 together.

[0033] When disassembling the mold body 2, the worker presses the side block 14, causing the side block 14 to move the locking block 13, so that the locking block 13 no longer locks the locking shell 10, allowing the first spring 5 to use its own elastic force to move the support shell 7 through the slider 6, fixing bolt 9 and threaded block 8, so that the support shell 7 separates from the mold body 2. The side block 14 is then released, allowing the second spring 12 to move the locking block 13 back to its original position.

[0034] By unscrewing the fixing bolt 9 out of the inner side of the slider 6, the support shell 7 can be replaced for different mold bodies 2.

[0035] During the molding process of the vulcanizing mold, the operator screws the threaded sleeve 20, which moves the threaded sleeve 20 between the interface 19 and the side opening 16 under the thread support of the interface 19. This further fixes the support shell 7. An external blowing device is connected through the external interface 18, and the external blowing device delivers air to the inside of the air collecting shell 17. The air inside the air collecting shell 17 moves into the inside of the side shell 15 through the interface 19 and the side opening 16, and is finally sprayed out from the nozzle 21 to cool the mold body 2, thereby preventing deformation caused by excessive temperature.

[0036] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
