Description

Technical Field

[0001] This utility model relates to the field of polyolefin elastomer technology, specifically a vulcanizing machine for producing polyolefin elastomers. Background Technology

[0002] Polyolefin elastomers are obtained by copolymerizing ethylene and olefins under the action of metallocene catalysts. Their molecular chains are composed of ethylene units and olefin units, and this structure gives them the properties of both plastics and rubber.

[0003] The vulcanizing machine heats the hot plate to the set vulcanization temperature through a heating system, while the hydraulic system applies a certain pressure. Under high temperature and high pressure, the vulcanizing agent reacts chemically with the rubber molecules, and sulfur atoms form crosslinks between the rubber molecular chains. This transforms the linear molecular structure of the rubber into a three-dimensional network structure, giving the rubber products good elasticity, strength, wear resistance, and aging resistance. Existing vulcanizing machines compress polyolefin elastomers into molds during processing, but the material adheres to the mold and is difficult to remove, reducing the working efficiency of the vulcanizing machine.

[0004] Therefore, the vulcanizing machine needs to be redesigned and modified to effectively prevent the problem of inconvenient material removal when polyolefin elastomers are pressed into shape during processing. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a vulcanizing machine for the production of polyolefin elastomers, which has the advantage of convenient material handling and solves the problem that when the vulcanizing machine compresses polyolefin elastomers into molds, it is inconvenient to handle the material while it adheres to the mold.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vulcanizing machine for producing polyolefin elastomers, comprising;

[0007] The vulcanizing machine body has a mold fixture fixedly connected to its top, a fixed box fixedly connected to the inner cavity of the mold fixture, and an ejection mechanism fixedly connected to the front and back ends of the inner cavity of the fixed box.

[0021] 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.

[0022] like Figures 1 to 4 As shown, the present invention provides a vulcanizing machine for producing polyolefin elastomers, comprising:

[0023] The vulcanizing machine body 1 has a model fixture 2 fixedly connected to its top. A fixed box 3 is fixedly connected to the inner cavity of the model fixture 2. An ejection mechanism 4 is longitudinally fixedly connected to the front and back ends of the inner cavity of the fixed box 3.

[0024] The ejection mechanism 4 includes a vertical rod 401, a sliding plate 402, an L-shaped clamping plate 403, an H-shaped plate 404, a connecting block 405, a T-shaped top plate 406, a support 407, an electric telescopic rod 408, a sleeve 409, and a transmission rod 410. The front and back ends of the inner cavity of the fixed box 3 are both longitudinally fixedly connected to the vertical rod 401. The sliding plate 402 is slidably sleeved on the surface of the vertical rod 401. The left and right sides of the sliding plate 402 are both fixedly clamped to the L-shaped clamping plate 403. The front end of the L-shaped clamping plate 403 is fixedly connected to the H-shaped plate 404. The center of the front end of the H-shaped plate 404 is fixedly connected to the connecting block 4. 05. The front end of the connecting block 405 passes through the front end of the fixed box 3 and is fixedly connected to a T-shaped top plate 406. The T-shaped top plate 406 is located inside the model fixture 2. The left side of the bottom of the inner wall of the fixed box 3 is fixedly connected to a support 407. The top right side of the support 407 is fixedly connected to an electric telescopic rod 408. The right side of the electric telescopic rod 408 is fixedly connected to a sleeve 409. The front end and back end of the sleeve 409 are both fixedly connected to a transmission rod 410. The front end of the transmission rod 410 is slidably connected to the surface of the slide plate 402. The front end and back end of the bottom of the inner wall of the fixed box 3 are both fixedly connected to a balancing mechanism 5.

[0025] refer to Figure 3 The balancing mechanism 5 includes a plate 51, a collar 52, and a connecting rod 53. The front and back ends of the bottom of the inner wall of the fixed box 3 are fixedly connected to the plate 51. The front and back ends of the transmission rod 410 are fixedly sleeved with the collar 52. The bottom of the collar 52 is fixedly connected to the connecting rod 53. The end of the connecting rod 53 away from the collar 52 is slidably connected to the top of the plate 51.

[0026] As a technical optimization of this utility model, by setting the balancing mechanism 5, the collar 52 can follow the transmission rod 410 to move. The movement of the collar 52 drives the connecting rod 53 to move stably on the surface of the plate 51, thereby supporting the smooth movement of the transmission rod 410.

[0027] refer to Figure 3 The front and back ends of the flat plate 51 are provided with grooves 6 at the positions corresponding to the connecting rod 53. The grooves 6 are used in conjunction with the connecting rod 53.

[0028] As a technical optimization of this utility model, the sliding groove 6 enables the connecting rod 53 to move left and right inside the sliding groove 6, while also serving as a limit, thus preventing the connecting rod 53 from tilting during movement.

[0029] refer to Figure 3 The surface of the slide plate 402 is provided with a guide groove 7 at the position corresponding to the transmission rod 410. The guide groove 7 is used in conjunction with the transmission rod 410.

[0030] As a technical optimization of this utility model, the guide groove 7 can assist the transmission rod 410 in its work and also serve as a limit, preventing the transmission rod 410 from detaching during movement.

[0031] refer to Figure 2 An opening 8 is provided at the front and back ends of the fixed box 3 and at the position corresponding to the connecting block 405. The opening 8 is used in conjunction with the connecting block 405.

[0032] As a technical optimization of this utility model, the opening 8 can assist the connecting block 405 in its work, avoiding the phenomenon that the connecting block 405 will get stuck at the opening 8 due to the narrow width of the opening 8.

[0033] refer to Figure 3 A support frame 9 is fixedly connected to the right side of the support 407. The end of the support frame 9 away from the support 407 is sleeved on the surface of the electric telescopic rod 408. The support frame 9 and the electric telescopic rod 408 are used together.

[0034] As a technical optimization of this utility model, the support frame 9 can assist the electric telescopic rod 408 in its work and also play a supporting and fixing role, thus preventing the electric telescopic rod 408 from shaking due to excessive load during operation.

[0035] The working principle and usage process of this utility model are as follows: When in use, the hydraulic system of the vulcanizing machine body 1 is started to apply a certain pressure, so that the rubber product is formed in the high temperature and high pressure environment of the mold fixture 2. Then, the electric telescopic rod 408 is started. The electric telescopic rod 408 retracts and drives the sleeve 409 and the transmission rod 410 to move synchronously. During the movement of the transmission rod 410, the collar 52 and the connecting rod 53 follow. The connecting rod 53 moves stably on the surface of the plate 51 in conjunction with the sliding groove 6. Then, the transmission rod 410 moves to the left and moves in conjunction with the guide groove 7, forcing the slide plate 402 to move upward. The upward movement of the slide plate 402 drives the L-shaped clamping plate 403 and the H-shaped plate 404 to move synchronously. The upward movement of the H-shaped plate 404 drives the connecting block 405 and the T-shaped top plate 406 to move accordingly. The T-shaped top plate 406 pushes the material out through the cavity of the mold fixture 2, thus making it convenient for the user to pick up the material.

[0036] In summary, this vulcanizing machine for producing polyolefin elastomers, through the coordinated use of the vulcanizing machine body 1, mold fixture 2, fixed box 3, ejection mechanism 4, vertical rod 401, sliding plate 402, L-shaped clamping plate 403, H-shaped plate 404, connecting block 405, T-shaped top plate 406, support 407, electric telescopic rod 408, sleeve 409, transmission rod 410 and balancing mechanism 5, solves the problem of inconvenient material removal from the mold when pressing polyolefin elastomers into shape during processing in existing vulcanizing machines.
