Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical parts processing, and in particular relates to a steel-rubber composite frame molded limiting structure. Background Art

[0002] The steel-rubber composite frame is an accessory product for mechanical equipment, mostly used in mining machinery and equipment, product grinding equipment and other fields. It is usually composed of a combination of wear-resistant steel and rubber. The wear-resistant steel mainly plays a supporting role, and the rubber coated on the surface of the wear-resistant steel mainly plays a role in buffering, shock absorption, and reducing wear.

[0003] At present, when processing steel-rubber composite skeletons, the wear-resistant steel needs to be pre-processed first, and then the wear-resistant steel and multiple pieces of raw rubber are placed inside the mold together. The raw rubber is melted by the molding process to increase the fluidity of the rubber so that it is coated on the surface of the wear-resistant steel. After cooling and molding, a rubber layer can be formed on the surface of the wear-resistant steel.

[0004] The specific operation process is as follows: pre-treat the wear-resistant steel → select a suitable mold → place a bump inside the mold to separate the wear-resistant steel and the inner wall of the mold (the thickness of the bump is the thickness of the rubber layer) → put raw rubber in the mold → use the molding process for thermoforming → cool and shape.

[0005] In the current prior art, when molding rubber on the surface of wear-resistant steel, it is necessary to place bumps inside the mold or directly use a mold with bumps, so as to achieve a gap between the wear-resistant steel and the mold and avoid the raw rubber from liquefying and flowing in the mold cavity during the molding process, causing a large extrusion force on the skeleton and causing the skeleton to shift. However, if the bumps are placed manually, they will need to be manually removed after cooling and molding, and the pits that appear will be repaired; if a mold with bumps is used, resistance will be generated during the demolding process after cooling and molding, affecting the demolding effect, and pits will also appear, which still need to be manually repaired in the subsequent processing process, which is not only cumbersome but also increases the processing cost. Utility Model Content

[0006] In order to solve the technical problem in the prior art that pits will appear in the rubber layer of the steel-rubber composite skeleton after demoulding, whether manually placing bumps or directly using a mold with bumps, the utility model provides a steel-rubber composite skeleton molded limiting structure.

[0016] Furthermore, the elastic component also includes a spring arranged inside the active cavity, and the spring is a thrust spring.

[0017] Beneficial effects of the utility model:

[0018] The utility model fixes the skeleton inside the mold by fixing a limit block on the steel block, forming a gap between the limit block and the inner wall of the mold, and forming a support between the limit block and the mold.

[0029] See also Figure 1 As shown, a steel-rubber composite skeleton molded limiting structure includes a connecting rib 2; a plurality of steel blocks 1 are fixedly connected to the connecting rib 2 at equal intervals; the connecting rib 2 and the plurality of steel blocks 1 form a skeleton;

[0030] Limiting blocks 3 are fixedly arranged at the positions corresponding to the bottom and the middle of the side of the steel block 1. The limiting blocks 3 are used to fix the skeleton and separate the skeleton from the mold.

[0031] Please refer again Figure 2As shown, the limit block 3 is a cylindrical structure, and a thread 4 is provided at one end of the limit block 3 close to the steel block 1, and the limit block 3 is connected to the thread 4 of the steel block 1 through the thread 4; a hexagonal block 5 is fixedly connected to the end of the limit block 3 away from the steel block 1, which is used to facilitate fixing the limit block 3 on the steel block 1.

[0032] Please refer again Figure 3-Figure 4 As shown, a movable cavity 6 is provided inside the limit block 3, and a slide bar 7 is slidably connected inside the movable cavity 6; an anti-dropping block 9 is fixedly connected to the slide bar 7 at a position corresponding to the bottom of the movable cavity 6, and the anti-dropping block 9 is used to prevent the slide bar 7 from falling off from the movable cavity 6; a top plate 8 is fixedly connected to the slide bar 7 at a position corresponding to the upper surface of the limit block 3, and the top plate 8 is used to contact the inner wall of the mold; an elastic component is provided inside the movable cavity 6, and the elastic component is used for the slide bar 7 to generate elastic deformation in the movable cavity 6;

[0033] A through hole 11 is provided at the center of the limiting block 3 ; a plurality of feed holes 12 are provided on the side wall of the limiting block 3 ; the upper end of the through hole 11 is connected to the active cavity 6 , and the lower end is connected to the plurality of feed holes 12 .

[0034] A plurality of protrusions 10 in a circumferential array are fixedly connected to the edge of the upper surface of the top plate 8 .

[0035] In specific use, firstly, the limit block 3 is fixed on the steel block 1 by using the threaded hole 4, and then the skeleton is directly placed in the mold, and the raw rubber block is placed in the mold to liquefy the raw rubber block by using the molding process or the rubber liquid is directly injected into the mold, and then the purpose of coating the skeleton with the rubber layer is achieved;

[0036] like Figure 3 As shown, since the limit block 3 is fixedly arranged on the steel block 1 on the skeleton, a gap is formed between the limit block 3 and the inner wall of the mold, and the support is formed between the limit block 3 and the mold to fix the skeleton inside the mold. During the molding process, the rubber liquid covers the skeleton together with the limit block 3, and there is no need to remove the limit block 3 from the rubber layer formed by cooling, so that no pits are generated. Not only does it not require additional manual pit repairing steps, it saves labor costs, and there will be no operational errors caused by manual labor, and it is also more convenient to demould.

[0037] like Figure 4As shown, in addition, since the inside of the mold will be full of pressure during molding, the rubber liquid will cover the surface of the skeleton. Therefore, during the molding process, if the rubber block is placed directly, it will be liquefied due to molding; if the rubber liquid is directly injected, the rubber liquid will enter the through hole 11 from the feed hole 12, and then enter the active cavity 6 from the through hole 11. Under the action of pressure, the continuously entering rubber liquid exerts an upward thrust on the anti-slip plate. At this time, the anti-slip plate drives the slide bar 7 to push outward, and the slide bar 7 drives the top plate 8 to push outward and abut against the inner wall of the mold, thereby achieving the purpose of the limit block 3 fixing the skeleton inside the mold. After demolding and cooling, the rubber layer completely wraps the gaps inside and outside the limit block 3. At this time, since the rubber layer is filled in the active cavity 6, when the skeleton supports external mechanical parts, the slide bar 7 on the limit block 3 can move in the active cavity 6 due to the elastic deformation of the rubber, thereby avoiding the conflict between the limit block 3 with greater hardness and the softer rubber layer, thereby causing the skeleton to locally damage the parts due to the raised active block when supporting external mechanical parts.

[0038] By fixing the protrusions 10 on the surface edge of the top plate 8, the rubber can be filled between the protrusions 10, thereby reducing the contact area between the top plate 8 and the mechanical parts and increasing the contact area between the rubber layer and the mechanical parts.

[0039] Please refer again Figure 5 As shown, a replaceable implementation is: by arranging a spring 13 inside the active cavity 6, the rubber liquid filled inside the active cavity 6 is eliminated, and the spring 13 is used to apply thrust to the anti-slip plate, so that the top plate 8 is abutted against the inside of the mold, so as to achieve the purpose of fixing the skeleton inside the mold. At this time, when the steel-rubber composite skeleton supports external mechanical parts, the limit block 3 can also be deformed when it contacts the external mechanical parts, and no local damage will be caused to the mechanical parts.
