Description

Technical Field

[0001] The utility model relates to the technical field of vulcanizing machines, in particular to a flat vulcanizing machine for silicone rubber. Background Art

[0002] Silicone rubber is a synthetic rubber with excellent heat resistance, cold resistance, electrical insulation and chemical stability. It can maintain good elasticity and mechanical properties even at extreme temperatures, making it widely used in industry.

[0003] A flat-plate vulcanizing press is one of the commonly used equipment in the production process of silicone rubber products. It is mainly used to heat and pressurize raw rubber to vulcanize and shape it. Vulcanization is the process of converting raw rubber into an elastomer with specific physical and mechanical properties through a chemical reaction. A flat-plate vulcanizing press is generally composed of heating plates, a hydraulic system, a frame and other parts. The working principle is to place the silicone rubber to be vulcanized between the heating plates, then apply pressure through the hydraulic system, and use the heat provided by the heating plates to cause the rubber material to undergo a vulcanization reaction. After vulcanization is completed, open the machine and take out the formed product.

[0004] In the process of vulcanizing silicone rubber using a flat vulcanizing press, workers are usually required to place the silicone rubber to be vulcanized into the mold groove of the template, cover it with a plywood, and then place the template and plywood between two heating plates. The two heating plates are then clamped with the silicone rubber through a hydraulic system, and pressurized and heated to vulcanize the silicone rubber into shape. After vulcanization, workers need to manually remove the template and plywood from between the two heating plates. Although workers wear gloves to prevent burns from the heating plates, they are inevitably negligent after working for a long time. When taking the template and plywood, their elbows and other places that are not protected by gloves touch the heating plates, resulting in burns from the heating plates.

[0005] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0028] The sliding mechanism 5 includes a fixed plate 51 fixed to both sides of the inner wall of the protective shell 3 near the top, and a sliding groove 52 is provided on the lower end surface of the fixed plate 51. A slider 53 is slidably connected in the sliding groove 52. The lower side of the slider 53 is connected to a top block 54 through the fixed plate 51. A telescopic rod 55 is provided on the lower side of the top block 54. The lower end of the telescopic rod 55 is fixed to the side plate 43. Telescopic power mechanisms 6 are installed on both sides of the rear end of the protective shell 3. The telescopic power mechanisms 6 are connected to the slider 53. The fixed plate 51 extends to the outside of the protective shell 3, so that the slider 53 can drive the telescopic rod 55, the side plate 43 and the assembly plate 4 to move to the outside of the protective shell 3.

[0029] The telescopic power mechanism 6 includes a hydraulic cylinder 2 61 installed on both sides of the rear end of the protective shell 3. The hydraulic cylinder 2 61 is provided with a reciprocating telescopic column 62. The reciprocating telescopic column 62 passes through the protective shell 3 and the fixed plate 51 and extends to the inside of the sliding groove 52 and is connected to the slider 53.

[0030] Specifically, refer to Figures 1-4After the silicone rubber template 41 to be vulcanized is placed in the mold groove, the template is covered with a clamping plate 42. Then, the lower heating plate 32 is pushed by the hydraulic cylinder 33, so that the lower heating plate 32 pushes the assembly plate 4 upward, so that the lower heating plate 32 and the upper heating plate 31 clamp the template 41 and the clamping plate 42 on the assembly plate 4. Then, the upper heating plate 31 and the lower heating plate 32 transfer heat to the template 41 and the clamping plate 42, so that the silicone rubber inside is vulcanized and formed. After the silicone rubber is vulcanized and formed, the hydraulic cylinder 33 drives the lower heating plate 32 to move downward, and the assembly plate 4 moves downward under the influence of gravity. At the same time, the side plates 43 on both sides are used to drive the telescopic rod 55 to extend, and then by starting the second hydraulic cylinder 61, the reciprocating telescopic column 62 pushes the slider 53 inside the sliding groove 52, and the slider 53 drives the top block 54 and the telescopic rod 55 to move, thereby driving the assembly plate 4 to move out of the protective shell 3 and out of the area between the upper heating plate 31 and the lower heating plate 32, so that it is convenient for the staff to remove the splint 42 and the vulcanized silicone rubber inside the template 41. During the operation, the staff stay away from the upper heating plate 31 and the lower heating plate 32 to avoid burns and improve safety;

[0031] When the silicone wire is vulcanized again, the silicone rubber to be vulcanized is placed in the mold groove of the template 41, covered with the clamping plate 42, and the assembly plate 4 is moved again between the upper heating plate 31 and the lower heating plate 32 by the hydraulic cylinder 2 61. Then, the lower heating plate 32 is pushed upward by the hydraulic cylinder 1 33. At this time, as the lower heating plate 32 moves upward, it drives the assembly plate 4 with it, and the side plate 43 of the assembly plate 4 pushes the telescopic rod 55, causing the telescopic rod 55 to retract, so as to ensure that the assembly plate 4 can move up and down normally.

[0032] Preferably, an assembly groove 44 corresponding to the template 41 is formed on the assembly plate 4 , and buckle notches 441 are provided on both sides of the assembly groove 44 .

[0033] Specifically, the template 41 can be removed from the assembly groove 44 by utilizing the latch notches 441 on both sides of the assembly groove 44 , so that a template 41 with a different mold groove can be replaced and installed into the assembly groove 44 .

[0034] Preferably, at least two diagonally symmetrical positioning grooves 45 are formed on the assembly plate 4 , and a positioning column 421 correspondingly plugged into the positioning groove 45 is provided at the lower end of the clamping plate 42 .

[0035] Specifically, when the splint 42 is covered on the template 41, the positioning column 421 under the splint 42 and the positioning groove 45 on the assembly plate 4 can be used to position the splint 42 to prevent the splint 42 from being displaced after placement, which would affect the vulcanization molding of the silicone rubber.

[0036] Preferably, a handle 46 is provided on the splint 42 , and the thickness of the handle 46 is smaller than that of the splint 42 .

[0037] Specifically, the setting of the handle 46 can facilitate the staff to remove the splint 42 from the template 41, and setting the thickness of the handle 46 to be smaller than the splint 42 can prevent the handle 46 from affecting the clamping and pressurizing of the splint 42 and the template 41 by the upper heating plate 31.

[0038] Preferably, the sliding groove 52 and the sliding block 53 are both in a “T”-shaped structure.

[0039] Specifically, the “T”-shaped structure is provided with a sliding groove 52 and a slider 53 , which can ensure that the slider 53 can slide inside the sliding groove 52 while preventing the slider 53 from being separated from the sliding groove 52 .

[0040] Preferably, four through holes are opened on the bottom box 1, and a directional sliding sleeve 7 is installed in the through hole. A directional sliding column 71 is installed in the directional sliding sleeve 7 in a sliding manner. A top plate 321 is provided at the four corners of the side end of the lower heating plate 32. The top end of the directional sliding column 71 is connected to the top plate 321, and the lower end extends to the inner cavity of the bottom box 1.

[0041] Specifically, when the hydraulic cylinder 33 drives the lower heating plate 32 to move up and down, the top plate 321 can drive the directional sliding column 71 to slide in a directional manner inside the directional sliding sleeve 7, thereby limiting the moving direction of the lower heating plate 32, reducing the shaking of the lower heating plate 32 when it is raised and lowered, and improving stability.

[0042] Preferably, a plurality of heat dissipation openings 34 are provided on the protective shell 3 .

[0043] Specifically, the plurality of heat dissipation openings 34 can facilitate the dissipation of heat inside the protective shell 3 to prevent the device from overheating.
