Description

Technical Field

[0001] The utility model relates to the technical field of mold rotating structures, in particular to a mold rotating structure. Background Art

[0002] A vulcanizer is a device used to vulcanize rubber. During the vulcanization process, rubber is heated and a vulcanizing agent (such as sulfur) or a vulcanization accelerator is added to cause a cross-linking reaction between its molecules, thereby enhancing its physical properties, such as strength, elasticity, and durability. A vulcanizer is usually a heating device that can control temperature and time to ensure that the rubber completes the vulcanization process under appropriate conditions. This process is a crucial step in rubber processing and is used to produce various rubber products, such as tires, seals, pipes, etc. At present, there is generally a mold on the vulcanizer, and the mold includes an upper mold and a lower mold. The rubber product is placed in the mold, and the rubber product undergoes a vulcanization reaction in the mold under high temperature and high pressure. After the vulcanization is completed, the product needs to be taken out. At present, some molds will remain in the upper mold after the rubber is vulcanized after the mold is opened, so the operator needs to squat or bend over to take out the rubber product, which is more troublesome.

[0015] The following will be combined with the drawings in 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 in 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.

They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0017] Embodiment 1: Embodiment 1 of the present utility model discloses a mold 3 rotating structure, such as Figure 1-2As shown, it includes a body 1, a mounting base 2 is arranged on the body 1, a mold 3 is arranged on the mounting base 2, during vulcanization, the mold 3 is in a horizontal state, a rotating shaft 31 is fixedly arranged on the side of the mold 3, the rotating shaft 31 is rotatably supported on the side wall of the mounting base 2, a driven gear 32 is coaxially fixedly sleeved on the rotating shaft 31, a driving gear 21 is arranged on the mounting base 2, the driving gear 21 is rotatably supported on the side wall of the mounting base 2, the driving gear 21 is meshed with the driven gear 32, and a driving member for driving the driving gear 21 to rotate is arranged on the mounting base 2.

[0018] Specifically, the driving member includes two hydraulic cylinders 4 fixedly mounted on the mounting seat 2 in the horizontal direction. The two hydraulic cylinders 4 are coaxially arranged. The piston rods of the two hydraulic cylinders 4 are fixedly connected. The piston rods of the two hydraulic cylinders 4 are connected with racks 41. The racks 41 are fixedly connected to the piston rods of the two hydraulic cylinders 4. The racks 41 are arranged in a direction parallel to the axial length of the hydraulic cylinders 4 and mesh with the driving gear 21. When the piston rod of one of the hydraulic cylinders 4 is extended, the piston rod of the other hydraulic cylinder 4 is pushed back at the same time, and the racks 41 are driven by the hydraulic cylinders 4 to move in the horizontal direction. The racks 41 drive the driving gear 21 to rotate, thereby driving the driven gear 32 and the mold 3 to rotate, so as to achieve a 180-degree flip of the mold 3. When the mold 3 is driven to return, the hydraulic cylinder 4 with the retracted piston rod re-extends the piston rod, which can drive the mold 3 to rotate in the opposite direction, so as to return the mold 3. In addition, a stroke adjustment screw 42 is arranged at the end of the hydraulic cylinder 4, and the stroke adjustment screw 42 can facilitate the operator to adjust the stroke of the hydraulic cylinder 4. In addition, a lifting cylinder 11 is fixedly installed on the machine body 1 in the vertical direction, and the piston rod of the lifting cylinder 11 is connected to the mounting seat 2. When the mold 3 needs to be flipped, the lifting cylinder 11 drives the mounting seat 2 to move upward, thereby providing sufficient rotation space for the flipping of the mold 3.

[0019] The implementation principle of the mold 3 rotation structure of the embodiment of the utility model is: the piston rod of the hydraulic cylinder 4 drives the rack 41 to move, and the rack 41 drives the driving gear 21 to rotate, thereby driving the driven gear 32 and the mold 3 to rotate, so as to realize a 180-degree flip of the mold 3, and then the operator can easily remove the rubber product on the flipped mold 3.

[0020] Embodiment 2: The difference from Embodiment 1 lies in that two limit cylinders are fixedly mounted on the side wall of the mounting seat 2 in the horizontal direction, and the two limit cylinders are arranged in a mirror-symmetrical manner along the rotating shaft 31. A limit block is fixedly arranged on the piston rod of the limit cylinder. Two limit grooves are provided on the side of the mold 3, and the limit blocks are plugged into the limit grooves. When the mold 3 is in a horizontal state, the two limit blocks are aligned with the positions of the two limit grooves. When the mold 3 is flipped, the piston rod of the limit cylinder extends out to drive the limit block to be inserted into the limit groove, thereby limiting the mold 3. Since the two limit cylinders are arranged in a mirror-symmetrical manner along the rotating shaft 31, after the mold 3 is restored, the two limit blocks can also be aligned with the two limit grooves on the mold 3, so that the limit blocks can be inserted into the limit grooves before and after the mold 3 is flipped.

[0021] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiments according to the technology of the utility model, which does not depart from the content of the technical solution of the utility model, belongs to the scope of the technical solution of the utility model.
