[0002] A shock-absorbing pad is a kind of bracket for a battery radiator in a new energy vehicle. Its function is to be able to movably connect the radiator, suppress or reduce vibrations during the driving of the vehicle, improve the quietness of the vehicle during driving, and be able to reduce the fixed linkage between the radiator and the vehicle, so that the vibrations of the vehicle can be reduced and transmitted to the radiator, thereby protecting the radiator;

[0003] The radiator bracket includes two parts, a metal bracket fixed to the vehicle body. There will be holes in the middle of the metal bracket. The other is a rubber sleeve installed in the holes of the metal bracket. The rubber sleeve in the metal bracket also needs to avoid falling off by setting limiters at the edges of the holes. At the same time, the size of the limiters has certain limitations. If it is too large, it may affect the deformation range of the rubber sleeve and reduce the service performance of the bracket and the rubber sleeve. Therefore, at present, the vulcanization method is used for connection, but the waste rubber cleaning is difficult in the vulcanization method, which affects the production efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a shock-absorbing rubber pad mold structure to solve the problem that the waste rubber cleaning of the rubber sleeve and the metal bracket affects the efficiency.

A plurality of mold holes for placing metal brackets are arranged in the middle mold. The lower mold is provided with a first column that inserts upward into the middle cavity of the metal bracket. A cavity for vulcanizing the rubber sleeve is formed between the first column and the cavity of the metal bracket. The upper mold is installed above the middle mold and closes the upper part of the mold holes. The upper mold is provided with a liquid injection groove for injecting glue into the mold holes.

[0006] Preferably, a strip-shaped block is arranged on the side of the mold hole above the middle mold. A diversion groove is arranged on the strip-shaped block. Branch grooves are arranged on both sides of the diversion groove. A converging groove is arranged in the center of the diversion groove.

[0007] Preferably, a liquid injection groove is arranged in the middle of the upper mold. The bottom of the liquid injection groove is communicated with the converging groove.

[0008] Preferably, the bottom of the upper mold is provided with a mold body covering the upper part of the mold hole. The upper mold is provided with a through hole communicated with the center of the mold body. When the upper mold and the middle mold are pressed together, there is a gap between the mold body and the first column.

[0009] Preferably, the liquid inlet end of the through hole is communicated with the branch groove.

[0010] Preferably, a second cylinder is arranged below the die body and embedded in the cavity.

[0011] Preferably, a first drainage groove is arranged along the cross-sectional contour of the upper end of the first cylinder, and a second drainage groove for drainage is arranged between the center of the upper end of the first cylinder and the first drainage groove.

[0012] Compared with the prior art, the shock-absorbing rubber pad mold structure proposed by the present invention adopts the above technical solutions and achieves the following technical effects:

[0013] The present invention can connect the rubber sleeve and the metal bracket by vulcanization.

DETAILED DESCRIPTION OF THE INVENTION

[0021] Embodiment

[0022] Please refer to Figures 1 - 6, the present invention provides a shock-absorbing rubber pad mold structure, including an upper mold 1, a middle mold 2 and a lower mold 3. A plurality of mold holes 21 for placing metal brackets 4 are provided in the middle mold 2. The lower mold 3 is provided with a first cylinder 31 that upwardly inserts into the middle cavity 100 of the metal bracket 4. A chamber 101 for a vulcanized rubber sleeve is formed between the first cylinder 31 and the cavity 100 of the metal bracket 4. The upper mold 1 is installed above the middle mold 2 and closes the upper part of the mold holes 21. The upper mold 1 is provided with a liquid injection groove 11 for injecting glue into the mold holes 21. In this solution, the metal bracket 4 is installed in the chamber 101 formed by the upper mold 1 and the middle mold 2. Its first cylinder 31 can shape the middle hole of the rubber sleeve. The upper mold 1 can close the upper part of the chamber 101. During the vulcanization process, the molten glue will flow from the upper mold 1 into the chamber 101 and cool in the cavity 100 of the metal bracket 4 to form a rubber sleeve. The side of the rubber sleeve will adhere to the side wall of the cavity 100 inside the metal bracket 4 and be fixed in the cavity 100 of the metal bracket 4. The rubber sleeve can prevent the limit fixation of metal parts and be stably installed in the cavity 100.

[0023] In a specific embodiment, referring to Figure 2 , Figure 4 , on the side of the mold holes 21 above the middle mold 2, there is a strip-shaped block 22. A diversion groove 221 is provided on the strip-shaped block 22. Branch grooves 222 are provided on both sides of the diversion groove 221. A confluence groove 223 is provided at the center of the diversion groove 221. In this solution, the glue will flow from the upper mold 1 into the confluence groove 223 and gather at the center of the confluence groove 223, and then flow to both sides along the diversion groove 221. The confluence groove 223 can prevent the glue flowing on the diversion groove 221 from being too thin and solidifying, which affects the pouring. In this application, two branch grooves 222 are respectively provided at both ends of each diversion groove 221, a total of four branch grooves 222, and each branch groove 222 corresponds to the pouring of a rubber sleeve.

[0024] In a specific embodiment, referring to Figure 1 , in the middle of the upper mold 1, there is a liquid injection groove 11. The bottom of the liquid injection groove 11 is communicated with the confluence groove 223. In this solution, the middle part and the bottom of the liquid injection groove 11 of the upper mold 1 are communicated, and the glue can flow downward from the liquid injection groove 11 into the confluence groove 223.

[0025] In a specific embodiment, referring to Figure 1 , Figure 2 , Figure 4, a mold body 12 covering above the mold hole 21 is provided at the bottom of the upper mold 1. A through hole 13 communicating with the center of the mold body 12 is provided on the upper mold 1. When the upper mold 1 is pressed against the middle mold 2, there is a gap 200 between the mold body 12 and the first cylinder 31; the liquid inlet end of the through hole 13 communicates with the branch groove 222; in this solution, the glue flowing on the branch groove 222 will flow along the through hole 13 to the center position of the mold body 12, and diffuse around and flow into the chamber 101 along the gap 200. After cooling at the position of the gap 200, a thin surface will be formed, which is convenient for personnel to clean from this place; further, the through hole 13 is inclined, which can increase the gap 200 at the ends of the two through holes 13, and then increase the interval between two adjacent chambers 101, which is convenient for the opening arrangement of the mold.

[0026] In a specific embodiment, referring to Figure 5 , a second cylinder 121 embedded in the cavity 100 is provided below the mold body 12; in this solution, a certain number of cavities 100 are provided in the rubber sleeve to reduce the thickness of the rubber sleeve at various angles and the amount of material used. It can make the rubber sleeve have a certain deformation ability and reduce the amount of material used for the rubber sleeve.

[0027] In a specific embodiment, referring to Figure 6 , a first drainage groove 311 is provided along the cross-sectional contour of the cylinder at the upper end of the first cylinder 31. A second drainage groove 312 for drainage is provided between the center of the upper end of the first cylinder 31 and the first drainage groove 311. When the glue flows down from the through hole 13, the glue will flow from the second drainage groove 312 to the first diversion groove 221 and diffuse, and uniformly flow down from the gap 200, which can ensure the uniformity of the glue flowing down and is convenient for cutting off the material after the colloid cools.

[0028] In this solution, the upper parts of the diversion groove 221, the first drainage groove 311, and the second drainage groove 312 are all in an exposed manner. When the upper mold 1 is separated from the middle mold 2, the waste glue in the through hole 13 will be disconnected from the waste glue in the branch groove 222. At this time, when the upper mold 1 is further pulled out, the waste glue in the through hole 13 will be pulled out from below the through hole 13 along with the rubber sleeve of the lower mold 3, thereby achieving the effect of rapid separation, which is convenient for personnel to clean and improves efficiency.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
