Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold for a rubber vulcanizer. Background Art

[0002] Vulcanized rubber refers to rubber that has been vulcanized and has characteristics such as non-stickiness and non-breakability. Most rubber products are made of this kind of rubber. When vulcanizing rubber, the rubber compound needs to be placed in a vulcanization mold and vulcanized by a rubber vulcanizer. After vulcanization, the product is taken out from the mold groove. Since the product fits tightly with the groove, it is very difficult for personnel to quickly take out the product. Patent 202321858220.9 discloses a mold for a rubber vulcanizer, which pushes the product out of the groove by moving the push plate upward to replace manual extraction. However, this technical solution uses a screw structure to drive the push plate to move upward, which requires a large number of rotations by personnel, consumes a lot of physical strength, and the moving speed of the push plate is slow. The extraction efficiency of rubber products needs to be further improved. Content of the Utility Model

A rubber compound groove is provided on the upper surface of the inner template, and a gear transmission groove is provided on the bottom surface of the inner template. A push plate, a retaining ring, a top plate, a threaded pipe sleeve, and a threaded rod are provided in the rubber compound groove. The retaining ring is fixedly connected to the inner wall of the rubber compound groove. The push plate matches the shape of the rubber compound groove, and the push plate is placed on the retaining ring. The top plate is located below the push plate. A plurality of sealing columns are vertically provided on the upper surface of the top plate. A plurality of air permeable holes matching the sealing columns are provided on the push plate. The threaded pipe sleeve is vertically and fixedly connected to the top plate. One end of the threaded rod is threadedly matched with the threaded pipe sleeve, and the other end of the threaded rod extends into the gear transmission groove. An air inlet channel and a driving shaft are provided in the inner template. One end of the air inlet channel communicates with the cavity formed by the push plate and the rubber compound groove, and the other end of the air inlet channel communicates with the outside. The driving shaft passes through the inner template and extends into the gear transmission groove, and the driving shaft is meshed with the threaded rod by bevel gears.

[0005] Further, the shapes of the retaining ring and the top plate match the shape of the rubber compound groove. The size of the top plate is smaller than that of the retaining ring, and the top plate passes through the retaining ring to push the push plate upward.

[0006] Furthermore, the side of the inner template is provided with a first opening and a second opening. Both the first opening and the second opening penetrate through the side wall of the bottom template and communicate with the outside. The air inlet passage extends into the first opening, and one end of the drive shaft extends into the second opening. A pipe joint is provided at the air inlet of the air inlet passage, and a sleeve is provided at the end of the drive shaft.

[0007] Furthermore, a second sealing plate is provided at the bottom of the inner template. The second sealing plate is fixedly connected to the inner template, and the second sealing plate encloses the gear transmission groove into a closed space.

[0008] The utility model has the following advantages: By rotating the drive shaft forward, the sealing column opens the air permeable holes, and uses external high-pressure gas to eject the rubber product, realizing the function of quick removal. Compared with the prior art, the number of rotation circles is reduced, and the removal efficiency is improved; By rotating the drive shaft reversely, the push plate can push out the rubber product, solving the abnormal situation that various gases cannot eject the rubber product, and expanding the use range of the equipment; The setting of the second sealing plate facilitates the installation and maintenance of the bevel gears meshed in the transmission gear groove.

The top template 1 and the bottom template 2 are hinged. A limiting rod 5 is integrally connected to the side surface of the inner template 4. The inner template 4 is inserted into the bottom template 2. The first sealing plate 3 fixes the inner template 4 in the bottom template 2 by screws. A rubber material groove 6 is formed on the upper surface of the inner template 4. The rubber material groove 6 is generally customized according to the shape of the product. The rubber material groove 6 is a non-circular groove. A gear transmission groove 21 is formed on the bottom surface of the inner template 4. A push plate 11, a retaining ring 10, a top plate 13, a threaded pipe sleeve 15, and a threaded rod 16 are installed in the rubber material groove 6.

[0017] The working principle of the present utility model: The initial position is as Figure 3On the right side, the sealing column is located within the ventilation holes. After an operator places the rubber compound on the push plate, closes the top template, and places it in a rubber vulcanizing machine for heating and vulcanization, upon completion of vulcanization, the operator inserts a Z-shaped crank into the sleeve and shakes the Z-shaped crank to drive the drive shaft to rotate the threaded rod. When the threaded rod rotates forward, the top plate moves downward until the sealing columns open the ventilation holes. By inserting an external high-pressure air pipe into the pipe joint and opening the valve, high-pressure gas enters the rubber compound tank. The high-pressure gas impacts the rubber product out of the rubber compound tank through the ventilation holes, achieving the function of quickly removing the product. For some products that cannot be ejected by high-pressure gas, the threaded rod is rotated reversely at this time, causing the top plate to move upward to eject the push plate and the rubber product together out of the rubber compound tank, expanding the scope of use of the mold. The setting of the second sealing plate facilitates the installation and maintenance of the bevel gear meshed in the transmission gear groove.

[0018] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
