Description

Technical Field

[0001] The utility model relates to a rubber vulcanizing device, in particular to a rubber vulcanizing device for producing rubber sealing parts. Background Art

[0002] Rubber vulcanization is the process of converting linear macromolecules into a three-dimensional network structure by adding crosslinking agents such as vulcanizing agents and accelerators under certain temperature and pressure conditions. During the vulcanization process, the vulcanizing agent chemically reacts with the rubber molecules to form crosslinks, transforming the linear macromolecules into a three-dimensional network structure. This changes the independent mobility of the molecular chains, resulting in excellent properties such as high strength, high elasticity, high wear resistance, and corrosion resistance.

[0003] For example, the Chinese patent publication number CN218576752U discloses a rubber vulcanizing device for producing rubber seals, which includes a base plate, universal wheels, a stamping mechanism for vulcanizing rubber seals, and a conveying mechanism for conveying rubber seals. Four universal wheels are arranged around the bottom of the base plate, the conveying mechanism is located above the base plate, and the stamping mechanism is located above the conveying mechanism. Beneficial effect: Through the combined action of the second electric push rod and the third electric push rod, the stamping plate at the lower end of the slide is moved to the required processing position, and then the product to be processed in the mold plate below is processed. After the processing, residual rubber may remain in the punching head, so the rubber in the punching head is blown into the second storage box below by the action of the air pump, and then it can be recycled for reuse next time;

[0004] The above-mentioned existing rubber vulcanizing device for producing rubber seals has some problems when used. First, rubber seals have various specifications. When vulcanizing rubber seals of other specifications, the mold plate needs to be replaced, but the mold plate is difficult to disassemble and replace. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-5 The utility model provides a technical solution: a rubber vulcanizing device for producing rubber seals, comprising a mounting seat 1 and a mold plate 5. The mold plate 5 is slidably installed in the mounting seat 1. Damping telescopic rods 103 are fixedly connected near the four corners of the mounting seat 1. A spring pad 105 is fixedly connected to the upper end of the damping telescopic rod 103. An extrusion spring 104 is sleeved on the damping telescopic rod 103. Mounting grooves 106 are provided on the front and rear inner walls of the mounting seat 1. A clamping block 3 is slidably installed in the mounting groove 106. A convex edge 302 is fixedly provided on the upper and lower rear surfaces of the clamping block 3. The convex edge 302 cooperates with the mold plate 5. Limiting grooves 4 are symmetrically provided on the top of the mounting seat 1. A limiting pin 402 is slidably installed in the limiting groove 4. Limiting grooves 301 are provided on both sides of the clamping block 3. The limiting groove 301 cooperates with the limiting pin 402.

[0022] In this embodiment, the convex edge 302 cooperates with the mold plate 5, and the upper and lower convex edges 302 are respectively clamped on the upper and lower sides of the mold plate 5, thereby connecting the clamping block 3 to the mold plate 5 together, and the limiting groove 301 cooperates with the limiting latch 402 to clamp the clamping block 3 inside the mounting groove 106. The clamping block 3 uses the convex edge 302 to clamp the main mold plate 5, thereby fixing the mold plate 5 inside the mounting seat 1, and moving the limiting latch 402 out of the limiting groove 301 to release the restriction on the clamping block 3. At this time, after the mold plate 5 is no longer restricted by the clamping block 3, the extrusion spring 104 pushes the spring pad 105 upward, and the spring pad 105 will press against the bottom of the mold plate 5, thereby The mold disc 5 is pushed to move and the mold disc 5 is pushed out of the mounting seat 1. The damping telescopic rod 103 has a certain damping, which limits the spring pad 105 from moving up too fast, so that the spring pad 105 slowly moves up to push the mold disc 5. After the mold disc 5 is moved out of the mounting seat 1, the clamping block 3 can be moved left and right to contact the connection between the clamping block 3 and the mold disc 5. At this time, other mold discs 5 can be replaced, which is convenient for replacing the mold disc 5 to perform vulcanization operations on rubber seals of other specifications. This device is only a mold disc 5 mounting component of the vulcanizer. The main body of the vulcanizer can refer to the rubber vulcanizing device for producing rubber seals with the publication number CN218576752U of the Chinese patent disclosure.

[0023] Among them, in order to achieve the purpose of vibrating the mounting base 1 up and down after flipping the connecting frame 2, this device adopts the following technical solution: limiting slide grooves 101 are symmetrically opened on both sides of the mounting base 1, and the inner walls of the limiting slide grooves 101 are gradually retracted upward. The mounting base 1 is sleeved with a connecting frame 2, and the inner walls of both sides of the connecting frame 2 are fixedly connected to limiting sliders 201. The limiting sliders 201 slide in cooperation with the limiting slide grooves 101. A vibration spring 102 is fixed in the limiting slide groove 101, and the upper end of the vibration spring 102 is fixedly connected to the limiting slider 201.

[0024] The limiting slider 201 slides with the limiting slot 101 to slide the connecting frame 2 and the mounting seat 1 together, and the inner walls on both sides of the limiting slot 101 gradually retract up and down, and then under the normal processing state, the limiting slider 201 is stuck in the retracted end of the limiting slot 101. After the connecting frame 2 is flipped over, the friction between the limiting slider 201 and the inner wall of the limiting slot 101 will cause the mounting seat 1 to move down slowly, and the internal space of the limiting slot 101 where the limiting slider 201 is located will gradually expand, and then the friction will gradually increase, and then the speed at which the connecting frame 2 moves down will gradually increase, causing the mounting seat 1 to fall rapidly, thereby compressing the vibration spring 102. After the inertia disappears, the vibration spring 102 will release the compressed energy to rebound the mounting seat 1, causing the mounting seat 1 to be in a state of up and down vibration, which is convenient for shaking out the rubber seal in the mold plate 5.

[0025] Among them, in order to achieve the purpose of pushing the limit pin 402, this device adopts the following technical solution: a return spring 401 is fixed in the limit groove 4, the other end of the return spring 401 is fixed to the limit pin 402, and a displacement block 403 is fixed on the limit pin 402.

[0026] The return spring 401 can generate a certain thrust for the limit pin 402 , and the limit pin 402 will be inserted into the limit slot 301 under the thrust, and the displacement block 403 can drive the limit pin 402 to move.

[0027] The working principle and usage process of the present invention are as follows: when in use, the connecting frame 2 needs to be connected to the vulcanizer body. When the mold disc 5 needs to be replaced, the displacement block 403 is used to drive the limiting pin 402 to move out of the limiting groove 301, thereby releasing the restriction on the clamping block 3. At this time, the mold disc 5 will be slowly pushed out from the inside of the mounting seat 1 under the push of the extrusion spring 104. After the clamping block 3 is removed, the mold disc 5 can be directly taken out, and then other mold discs 5 can be replaced for continued use.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
