Description

Technical Field

[0001] The utility model relates to the technical field of rubber vulcanization, in particular to a rubber sealing material vulcanization device. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force, and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and a large molecular weight, greater than hundreds of thousands. Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from plants such as rubber trees and rubber grass; synthetic rubber is obtained by polymerization of various monomers. In the process of rubber production, it needs to be vulcanized using a vulcanization device.

[0003] As disclosed in a Chinese patent: A rubber sealing ring vulcanization device, application number: CN202220346735.X, comprising a vulcanizer body and a hydraulic press, the hydraulic press is connected to the vulcanizer body through a hydraulic pipe, the vulcanizer body is provided with a first fixed plate and a second fixed plate, the corners of the vulcanizer body are provided with guide pillars, the guide pillars are provided with a guiding device, the guiding device comprises a first fixed ring, matching teeth, a second fixed ring, a first telescopic spring, a reserved groove and a rubber ring, the first fixed ring is connected to the corner of the first fixed plate. The rubber sealing ring vulcanization device described in the utility model belongs to the technical field of rubber production, and the first fixed ring and the second fixed ring are matched, and the first telescopic spring between the first fixed ring and the second fixed ring is used for buffering during mold closing to reduce the buffer between the first fixed plate and the second fixed plate, thereby preventing the first fixed plate and the second fixed plate from loosening during mold closing.

[0004] However, in the above technical solution, with the rapid development of society and technology, people have higher and higher requirements for vulcanization devices. Most of the vulcanization devices on the market now adopt high-temperature vulcanization. Therefore, some rubber sealing materials that are not very resistant to high temperatures are easily partially adhered to the vulcanization lower mold due to the high temperature during high-temperature vulcanization. The current vulcanization device cannot automatically remove the rubber sealing material adhered to the vulcanization lower mold from the vulcanization lower mold, which affects the subsequent processing efficiency.

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 and Figure 2As shown, a rubber sealing material vulcanization device includes a device body 1, on which a vulcanization lower mold 2 is arranged, on which a rotating column 3 is arranged, and at both ends of the rotating column 3, a first one-way rotating ratchet 4 and a second one-way rotating ratchet 5 are respectively arranged, and a vulcanization upper mold 6 is arranged on the device body 1, and on the outer wall surfaces of both sides of the vulcanization upper mold 6, a first push plate 7 and a second push plate 8 are arranged, and the first push plate 7 and the second push plate 8 are respectively provided with a first ratchet bar 9 and a second ratchet bar 10, and a baffle bar 11 is arranged on the side of the device body 1 close to the vulcanization lower mold 2.

[0024] like Figure 3 and Figure 4 As shown, in another embodiment of the utility model, the vulcanization lower mold 2 includes a lower mold base 201, and limiting grooves 202 are arranged on both sides of the lower mold base 201. A template 203 is arranged above the lower mold base 201, and a plurality of vulcanization placement grooves 204 are arranged on the template 203. A through groove 205 is arranged on the inner wall below the vulcanization placement groove 204, and a sealing bottom column 206 is arranged in the through groove 205;

[0025] The lower mold base 201 is provided with a plurality of sliding limit grooves 207, and the sliding limit grooves 207 are provided with elastic columns 208. A limit block 209 is provided at one end of the elastic column 208 away from the template 203. When vulcanization is required, the rubber sealing material is first placed in the vulcanization placement groove 204, and then the vulcanization upper mold 6 is fitted with the template 203 for vulcanization. After the vulcanization is completed, the vulcanization upper mold 6 is separated from the template 203, and then the column 3 is rotated to rotate the lower mold base 201 180 degrees. At the same time, the limit grooves 202 and the blocking bar 11 are used to limit the rotation angle of the lower mold base 201. The lower mold base 201 drives the template 203 to rotate. At this time, the template 203 is located below the lower mold base 201. Under the action of gravity, the template 203 is separated from the lower mold base 201. The lower template 203 drives the vulcanization placement groove 204 and the elastic column 208 to move, and the vulcanization placement groove 204 is used to separate the rubber sealing material in the vulcanization placement groove 204 from the sealing bottom column 206 to prevent the rubber sealing material from adhering to the sealing bottom column 206. At the same time, the elastic column 208 drives the limit block 209 to move, and the limit block 209 and the sliding limit groove 207 are used to limit the moving distance of the elastic column 208, and then the elastic column 208 is used to limit the moving distance of the lower template 203. During this period, the elastic column 208 is used to make the lower template 203 move up and down repeatedly, so that the rubber sealing material is separated from the vulcanization placement groove 204, which can effectively separate the vulcanized rubber sealing material from the vulcanization lower mold 2, and prevent the vulcanized rubber sealing material from adhering to the vulcanization lower mold 2.

[0026] The working principle of this rubber sealing material vulcanization device:

[0027] When in use, first put the rubber sealing material into the vulcanization placement groove 204, and then use the device body 1 to fit the vulcanization upper mold 6 with the template 203, at this time, the vulcanization upper mold 6 drives the first push plate 7 and the second push plate 8 to move, and the first push plate 7 and the second push plate 8 respectively drive the first ratchet bar 9 and the second ratchet bar 10 to move, at this time, the movement direction of the first ratchet bar 9 and the second ratchet bar 10 cannot make the first one-way rotating ratchet 4 and the second one-way rotating ratchet 5 rotate, and then vulcanization can be carried out. After the vulcanization is completed, the vulcanization upper mold 6 is separated from the template 203, and the vulcanization upper mold 6 drives the first ratchet bar 9 and the second ratchet bar 10 to move again, at this time, the movement direction of the first ratchet bar 9 and the second ratchet bar 10 can make the first one-way rotating ratchet 4 and the second one-way rotating ratchet 5 rotate;

[0028] After the vulcanizing upper mold 6 moves a certain distance, the first ratchet bar 9 meshes with the first one-way rotating ratchet wheel 4, so that the first one-way rotating ratchet wheel 4 rotates, and the first one-way rotating ratchet wheel 4 rotates the lower mold base 201 by 180 degrees through the rotating column 3. At the same time, the limiting groove 202 and the blocking bar 11 are used to limit the rotation angle of the lower mold base 201. Then, under the action of gravity, the template 203 is separated from the lower mold base 201, and the lower template 203 drives the vulcanizing placement groove 204 and the elastic column 208 to move, and the vulcanizing placement groove 204 is used to make the vulcanizing placement groove 204 The rubber sealing material in the vulcanization mold 2 is separated from the sealing bottom column 206 to prevent the rubber sealing material from adhering to the sealing bottom column 206, and the elastic column 208 is used to repeatedly move the lower template 203 up and down, so that the rubber sealing material is removed from the vulcanization placement groove 204, and the rubber sealing material adhering to the vulcanization lower mold 2 can be automatically taken out from the vulcanization lower mold 2, and then the vulcanization upper mold 6 continues to move, the first ratchet bar 9 is engaged and disengaged from the first unidirectional rotating ratchet 4, and the second ratchet bar 10 is engaged with the second unidirectional rotating ratchet 5, so that the vulcanization lower mold 2 returns to its original position.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description.
