Description

Technical Field

[0001] This utility model belongs to the technical field of rubber vulcanizing machines, and in particular relates to a heating structure for rubber vulcanizing machines. Background Technology

[0002] A rubber vulcanizing machine is a piece of equipment specifically used in the production process of rubber products. Its main function is to heat and pressurize the rubber products to complete the vulcanization process. Vulcanization is a key step in the production of rubber products. Through this process, cross-linking bonds are formed between the rubber molecular chains, thereby enabling the rubber to obtain the required physical properties, such as tensile strength, abrasion resistance, tear resistance, and elasticity.

[0003] The rubber vulcanizing machine provides the specific pressure and temperature required during the vulcanization process through its internal hydraulic system and heating medium. In order to keep the position of the heat-conducting mold fixed when the lifting support applies pressure to the heat-conducting mold, a heating structure for the rubber vulcanizing machine is designed. This structure restricts the position of the two heat-conducting molds through a limiting support frame and a trapezoidal limiting strip. That is, when the lifting support rises and applies pressure to the heat-conducting mold, the position of the two heat-conducting molds is fixed, so as to avoid misalignment of the two heat-conducting molds. Utility Model Content

[0004] The purpose of this invention is to provide a heating structure for a rubber vulcanizing machine, which, when the lifting support seat rises and pressure is applied to the heat-conducting and shaping mold, fixes the position of the two heat-conducting and shaping molds to prevent misalignment of the two heat-conducting and shaping molds, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A heating structure for a rubber vulcanizing machine includes a lifting support base slidably connected to the inner cavity of the rubber vulcanizing device; a heating base is installed on the top of the lifting support base; a limiting support frame is fixedly connected to the top of the heating base; rectangular grooves are opened on both the left and right sides of the inner cavity of the limiting support frame; a supporting connecting piece is slidably connected to the inner cavity of each of the two rectangular grooves; a slotted spring piece is welded between the supporting connecting piece and the inner cavity of the rectangular groove; and a trapezoidal limiting strip is fixedly connected to the opposite side of each of the two supporting connecting pieces.

[0006] Preferably, the inner cavity of the limiting support frame is slidably connected to two heat-conducting shaping molds, and a U-shaped handle is welded to the front side of each of the two heat-conducting shaping molds.

[0007] Preferably, a movable thin plate is slidably connected to the inner cavity of the heating base, and a spring plate is welded between the movable thin plate and the rear side of the inner cavity of the limiting support frame.

[0008] Preferably, the surface of the movable thin plate is slidably connected to the heat-conducting and shaping mold, and the bottom of the rubber vulcanizing device is fixedly connected to a support base by bolts.

[0009] Preferably, an operating box is fixedly connected to the left side of the top of the support base by bolts. The operating box is connected to the rubber vulcanizing device. An elongated rectangular piece is fixedly connected to the side of the support connecting piece opposite to the trapezoidal limiting strip.

[0010] Preferably, the side of the elongated rectangular piece opposite to the trapezoidal limiting strip extends through to the surface of the limiting support frame and is fixedly connected with a heat insulation protection strip, and the surface of the elongated rectangular piece is slidably connected to the inner cavity of the slotted spring piece.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model pushes the heat-conducting shaping mold to drive the trapezoidal limiting strip to slide into the inner cavity of the rectangular groove, and compresses the slotted spring sheet. Then, the trapezoidal limiting strip is reset under the rebound force of the slotted spring sheet, and the two trapezoidal limiting strips restrict the position of the heat-conducting shaping mold. This achieves the purpose of fixing the position of the two heat-conducting shaping molds when pressure is applied to the heat-conducting shaping mold after the lifting support seat rises, so as to avoid misalignment of the two heat-conducting shaping molds.

[0013] 2. By using the movable thin plate and the spring plate together, this utility model allows the spring plate to push the heat-conducting mold when it is pulled out through the U-shaped handle, making it easier to pull the heat-conducting mold out of the inner cavity of the limiting support frame.

[0014] 3. By setting up a heat-insulating protective strip, this utility model can provide heat insulation protection between the operator's fingers and the surface of the extended rectangular piece when the heat-conducting and shaping mold needs to be pulled out and the extended rectangular piece is pulled so that the trapezoidal limiting strip slides back into the rectangular groove cavity, thus avoiding accidental burns to the operator.

Detailed Implementation

[0023] In the following description, embodiments of the heating structure for a rubber vulcanizing machine according to the present invention will be described with reference to the accompanying drawings.

[0024] Example 1:

[0025] Figure 1-5 This invention illustrates a heating structure for a rubber vulcanizing machine according to an embodiment of the present invention. The structure includes: a lifting support base 2 slidably connected to the inner cavity of a rubber vulcanizing device 1; a heating base 3 mounted on the top of the lifting support base 2; a limiting support frame 4 fixedly connected to the top of the heating base 3; rectangular grooves on both the left and right sides of the inner cavity of the limiting support frame 4; supporting connecting pieces 5 slidably connected to the inner cavities of both rectangular grooves; slotted spring pieces 6 welded between the supporting connecting pieces 5 and the inner cavities of the rectangular grooves; trapezoidal limiting strips 7 fixedly connected to opposite sides of both supporting connecting pieces 5; and two heat-conducting shaping molds 8 slidably connected to the inner cavity of the limiting support frame 4. The front side of the mold 8 is welded with a U-shaped handle 9. The inner cavity of the heating base 3 is slidably connected with a movable thin plate 10. A spring plate 11 is welded between the movable thin plate 10 and the rear side of the inner cavity of the limiting support frame 4. The surface of the movable thin plate 10 is slidably connected to the heat-conducting mold 8. The bottom of the rubber vulcanizing device 1 is fixedly connected with a support base 12 by bolts. With the cooperation of the movable thin plate 10 and the spring plate 11, when the heat-conducting mold 8 is pulled out through the U-shaped handle 9, the rebound force of the spring plate 11 can push the heat-conducting mold 8. This makes it easier to pull the heat-conducting mold 8 out of the inner cavity of the limiting support frame 4.

[0026] Example 2:

[0027] Figure 1-5This invention illustrates a heating structure for a rubber vulcanizing machine according to an embodiment of the present invention. The structure includes: a lifting support base 2 slidably connected to the inner cavity of a rubber vulcanizing device 1; a heating base 3 mounted on the top of the lifting support base 2; a limiting support frame 4 fixedly connected to the top of the heating base 3; rectangular grooves on both the left and right sides of the inner cavity of the limiting support frame 4; supporting connecting pieces 5 slidably connected to the inner cavities of both rectangular grooves; slotted spring pieces 6 welded between the supporting connecting pieces 5 and the inner cavities of the rectangular grooves; trapezoidal limiting strips 7 fixedly connected to opposite sides of both supporting connecting pieces 5; and an operating box 13 bolted to the left side of the top of the support base 12. The operating box 13 is connected to the rubber vulcanizing device 1. The device 1 is connected, and an extended rectangular piece 14 is fixedly connected to the side of the support connecting piece 5 opposite to the trapezoidal limiting strip 7. The side of the extended rectangular piece 14 opposite to the trapezoidal limiting strip 7 extends through to the surface of the limiting support frame 4 and is fixedly connected to a heat insulation protection strip 15. The surface of the extended rectangular piece 14 is slidably connected to the inner cavity of the slotted spring piece 6. With the setting of the heat insulation protection strip 15, when the heat-conducting shaping mold 8 needs to be pulled out, and the extended rectangular piece 14 is pulled so that the trapezoidal limiting strip 7 slides back into the inner cavity of the rectangular groove, the operator's fingers are protected from heat insulation between the extended rectangular piece 14 and the surface of the extended rectangular piece 14, so as to avoid accidental burns to the operator.

[0028] Working principle: When using this utility model, the user merges the two heat-conducting shaping molds 8 vertically and slides them from front to back into the inner cavity of the limiting support frame 4. When the rear side of the heat-conducting shaping mold 8 contacts the surface of the trapezoidal limiting strip 7, the pushing force of the heat-conducting shaping mold 8 and the special shape of the surface of the trapezoidal limiting strip 7 will push the trapezoidal limiting strip 7 to slide, causing the two trapezoidal limiting strips 7 to slide back to back and into the inner cavity of the rectangular groove, thereby compressing the slotted spring plate 6. When the rear side of the heat-conducting shaping mold 8 contacts the front side of the movable thin plate 10, it continues to be pushed backward until the trapezoidal limiting strip 7 is reset under the rebound force of the slotted spring plate 6, and the two trapezoidal limiting strips 7 restrict the position of the heat-conducting shaping mold 8. Thus, when the lifting support seat 2 rises and applies pressure to the heat-conducting shaping mold 8, the position of the two heat-conducting shaping molds 8 is fixed to prevent misalignment.

[0029] In summary, the heating structure of this rubber vulcanizing machine pushes the heat-conducting shaping mold 8 to slide the trapezoidal limiting strip 7 into the inner cavity of the rectangular groove, compressing the slotted spring plate 6. Subsequently, the trapezoidal limiting strip 7 is reset under the rebound force of the slotted spring plate 6, thus restricting the position of the heat-conducting shaping mold 8. This achieves the purpose of fixing the position of the two heat-conducting shaping molds 8 when pressure is applied to the heat-conducting shaping mold 8 after the lifting support seat 2 rises, thereby preventing misalignment of the two heat-conducting shaping molds 8.
