Description

Technical Field

[0001] This utility model relates to the technical field of vulcanizing machines, and in particular to a structure that improves the safety of mold opening. Background Technology

[0002] In the production of rubber products, vulcanizing machines play a crucial role. They use a high-temperature, high-pressure environment to induce a reaction between the rubber and the vulcanizing agent, constructing a three-dimensional network structure of rubber molecules. This significantly enhances the key properties of rubber products, such as strength, hardness, elasticity, and abrasion resistance. Vulcanizing machines are widely used in many fields, including automobile tire manufacturing, industrial seal production, rubber pipe processing, rubber sealing product manufacturing, rubber flooring production, and rubber vibration damping device manufacturing, and have become an indispensable core piece of equipment in the rubber industry production process.

[0003] Currently, vulcanizing machines generally use molds to vulcanize rubber. After vulcanization is complete, the mold needs to be opened. Some models of vulcanizing machines have a mold-lifting shaft with a rotating shaft on it. One side of the mold is rotatably connected to the rotating shaft. When opening the mold, the mold is rotated to open it. However, in actual operation, due to the long lever arm of the mold-lifting shaft, the mold-lifting shaft is prone to breakage from the root due to the force of the mold, causing the mold to fall and injure personnel, which is not very safe. Utility Model Content

[0004] To improve production safety, this utility model provides a structure that enhances mold-opening safety, addressing the problems of existing technologies.

[0005] This utility model provides a structure to improve the safety of mold lifting, which adopts the following technical solution:

[0006] A structure for improving mold-lifting safety includes a body, a base plate disposed on the body, a mold-lifting shaft disposed on the base plate, and a mold disposed on the base plate. A rotating shaft is disposed on the mold-lifting shaft, and one side of the mold is rotatably connected to the rotating shaft. A bearing seat is fixedly disposed on the base plate and is fixedly sleeved on the mold-lifting shaft.

[0007] Preferably, one end of the bearing seat is provided with a threaded hole, one end of the mold-lifting shaft is provided with a thread on its circumferential surface, and one end of the mold-lifting shaft is threadedly connected to the threaded hole.

[0008] Preferably, the end of the bearing seat near the base plate is provided with a screw hole, and the bearing seat and the base plate are threadedly connected by a bolt.

[0009] Preferably, the machine body is provided with a track plate, the track plate is provided with a track, the track is bent, the side of the mold is provided with a limiting shaft, one end of the track faces the limiting shaft, the other end of the track faces the top of the base plate, and the limiting shaft slides with the track.

[0010] Preferably, a limit cylinder is provided on the track plate, and the piston rod of the cylinder is provided with a safety shaft.

[0011] In summary, this utility model includes at least one of the following structural advantages for improving mold-lifting safety:

[0012] When the mold is lifted, the base plate slides out of the machine body, and at the same time, the limiting shaft on the side of the mold slides into the track. When the base plate slides further, the mold rotates upward around the pivot under the action of the track, thereby opening the mold and making it convenient for the operator to take out the product. Since the mold lifting shaft is connected to the shaft seat, the lever arm of the mold lifting shaft is reduced, which reduces the force on the root of the mold lifting shaft, making the mold lifting shaft less likely to break and cause a safety accident.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

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

[0019] This utility model discloses a structure to improve the safety of mold lifting, such as... Figure 1-3 As shown, it includes a body 1, a base plate slidably mounted on the body 1, a mold-lifting shaft 2 vertically mounted on the base plate, and a mold 3 mounted on the base plate. A rotating shaft is fixedly mounted on the side wall of the mold-lifting shaft 2 in the horizontal direction. One side of the mold 3 is rotatably connected to the rotating shaft. There are two mold-lifting shafts 2 on the base plate. The two mold-lifting shafts 2 are located on opposite sides of the base plate. The two ends of the rotating shaft are fixedly connected to the two mold-lifting shafts 2 respectively.

[0020] Meanwhile, a bearing seat 4 is fixedly installed on the base plate along the vertical direction. A screw hole is opened at the end of the bearing seat 4 near the base plate. A bolt is threadedly connected between the bearing seat 4 and the base plate, and the bolt is threaded into the screw hole. At the same time, a threaded hole is opened at the end of the bearing seat 4 away from the base plate. A thread is provided on the circumferential surface of one end of the mold lifting shaft 2, and one end of the mold lifting shaft 2 is threaded into the threaded hole.

[0021] Meanwhile, track plates 51 are fixedly installed on both opposite sides of the body 1. Tracks 51 are formed on the inner sidewalls of track plates 51, and are bent. Limiting shafts 31 are fixedly installed on both opposite sides of the mold 3. One end of the track 51 faces the limiting shaft 31, and the other end faces the top of the base plate. The limiting shaft 31 slides with the track 51. When the base plate slides, it moves the mold 3. When the mold 3 moves to the track plate 51, the limiting shaft 31 on the mold 3 enters the track 51. When the base plate slides further, the mold 3 rotates upwards around the pivot under the action of the track 51, thus opening the mold 3. Furthermore, the diameter of the end of the track 51 facing the limiting shaft 31 is larger than the diameter of the limiting shaft 31, thus preventing the shaft from jamming. In addition, a limit cylinder 6 is fixedly installed on the track 51 plate 5 in the horizontal direction. The limit cylinder 6 is set in a direction perpendicular to the track 51 plate 5. A safety shaft 61 is fixedly installed on the piston rod of the cylinder. When the mold 3 is opened on the track 51 plate 5, the piston rod of the cylinder extends and the safety shaft 61 abuts against the lower surface of the mold 3, thereby restricting the mold 3. In this way, even if the mold lifting shaft 2 breaks, the safety shaft 61 can still prevent the mold 3 from falling.

[0022] The implementation principle of the structure for improving mold-lifting safety in this utility model embodiment is as follows: When lifting the mold, the bottom plate slides out of the machine body 1, and at the same time, the limiting shaft 31 on the side of the mold 3 slides into the track 51. When the bottom plate slides further, the mold 3 rotates upward around the pivot under the action of the track 51, thereby opening the mold 3 and making it convenient for the operator to take out the product. Since the mold-lifting shaft 2 is connected to the shaft seat 4, the lever arm of the mold-lifting shaft 2 is reduced, which reduces the force on the root of the mold-lifting shaft 2, thereby making the mold-lifting shaft 2 less likely to break and cause a safety accident.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
