Description

A non-powered mold opening structure Technical Field

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

[0002] Vulcanization, a core process in the rubber industry, initially relied on simple heating and sulfur mixing, resulting in low production efficiency and inconsistent quality. Since the 20th century, with the surge in demand for rubber products during the Industrial Revolution (such as tires and seals), vulcanization equipment has gradually evolved from manual operation to mechanization and automation. As core equipment, the technological innovation of vulcanizing machines has consistently focused on improving temperature uniformity, pressure control precision, energy efficiency, and process adaptability.

[0003] Vulcanizing machines are generally equipped with molds, including an upper mold and a lower mold. The rubber product is placed between the upper and lower molds, and then the hydraulic cylinders of the vulcanizing machine apply pressure to the molds, vulcanizing the rubber in a high-temperature and high-pressure environment. After vulcanization is complete, the molds need to be removed, and the upper and lower molds need to be opened to facilitate the operator to take out the product. However, currently, mold moving and opening generally involves moving the mold out of the vulcanizing machine and then using a cylinder or hydraulic cylinder to separate the upper and lower molds. However, this mold opening method has many structures and is relatively expensive. Summary of the Invention

[0004] To simplify the mold opening structure and reduce costs, this utility model provides a non-powered mold opening structure to address the problems of the prior art.

[0005] This utility model provides a non-powered mold opening structure, which adopts the following technical solution:

[0006] A non-powered mold-opening structure includes a body, which has an upper seat and a lower seat. An upper mold and a lower mold are disposed between the upper seat and the lower seat. The lower mold is slidably disposed on the lower seat. A mold-lifting shaft is disposed on one side of the lower mold, and a sliding sleeve is slidably sleeved on the mold-lifting shaft. One side of the upper mold is rotatably connected to the sliding sleeve. A lifting plate is disposed on the upper seat, and an elongated hole is disposed on the lifting plate. A limit bolt is threaded on the upper seat, and the threaded part of the limit bolt movably passes through the elongated hole. The other side of the upper mold is rotatably connected to the lifting plate.

[0007] Preferably, a limiting piece is provided at the end of the mold-lifting shaft.

[0008] Preferably, the lower base is provided with a plurality of support seats, and rollers are rotatably provided on the support seats, and the lower mold slides in cooperation with the rollers.

[0009] Preferably, limit rails are provided on both opposite sides of the lower base, and limit grooves are provided on the inner side of the limit rails, with the opposite sides of the lower mold embedded in the limit grooves.

[0010] Preferably, the lower seat is provided with a spring seat, the spring seat is provided with a receiving groove, the receiving groove is provided with a spring, one end of the spring is fixedly connected to the spring seat, and the other end of the spring is fixedly connected to the support seat.

[0011] In summary, the present invention includes at least one of the following beneficial technical effects of a non-powered mold opening structure:

[0012] During mold opening, the upper seat of the machine body rises upward, which in turn raises the lifting plate. The lifting plate moves downward through the elongated hole until the end of the elongated hole abuts against the limit bolt. Then, the lifting plate raises the upper mold. During the raising process, the sliding sleeve is subjected to oblique tension, which causes the sliding sleeve to rise while the upper mold pulls the lower mold outside the machine body through the sliding sleeve. At the same time, it rotates around the sliding sleeve as the center, opening a certain angle between the upper and lower molds. This makes it convenient for operators to pick up the product, thus eliminating the need for an additional power mechanism to move the mold out and open the mold, simplifying the structure and reducing costs.

[0019] 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.

[0020] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. 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.

[0021] This utility model discloses a non-powered mold opening structure, as shown in Figures 1-5. It includes a body with an upper seat 1 and a lower seat 2. The upper seat 1 is located directly above the lower seat 2. An upper mold 3 and a lower mold 4 are arranged between the upper seat 1 and the lower seat 2. The lower mold 4 is slidably mounted on the lower seat 2. At the same time, multiple support seats 21 are arranged on the lower seat 2, which are arranged in two rows. Rollers 211 are arranged on the upper surface of the support seats 21. The ends of the rollers 211 are rotatably supported on the support seats 21. The opposite sides of the lower mold 4 are supported on the rollers 211. The lower mold 4 and the rollers 211 slide in cooperation. In this way, when the lower mold 4 moves, the sliding friction of the lower mold 4 is converted into rolling friction, and the friction force is smaller.

[0022] In addition, a spring seat 231 is fixedly installed on the lower base 2. The top of the spring seat 231 has a receiving groove, and the spring 231 is placed in the receiving groove. One end of the spring 231 is fixedly connected to the spring seat 231, and the other end of the spring 231 is fixedly connected to the support base 21. The spring 231 can play a role in damping the support base 21, thereby damping the lower mold 4. This can reduce the vibration of the lower mold 4 during its movement. In addition, limit rails 22 are fixedly installed on opposite sides of the lower base 2. The lower mold 4 is located between the two limit rails 22. The limit rails 22 have limit grooves 221 facing the side of the lower mold 4. The opposite sides of the lower mold 4 are embedded in the limit grooves 221. The limit rails 22 can guide and limit the lower mold 4, making it less likely for the lower mold 4 to deviate.

[0023] Additionally, a lifting shaft 41 is fixedly installed on one side of the lower mold 4. The lifting shaft 41 is arranged along a plane perpendicular to the lower mold 4. One end of the lifting shaft 41 is fixedly connected to the lower mold 4. A sliding sleeve 42 is slidably sleeved on the lifting shaft 41. One side of the upper mold 3 is rotatably connected to the sliding sleeve 42. At the same time, a lifting piece 11 is provided on the upper seat 1. The lifting piece 11 has an elongated hole 111. A limit bolt is threaded onto the upper seat 1. The threaded part of the limit bolt movably passes through the elongated hole 111 and is connected to the upper seat 1. This can limit the lifting piece 11 on the upper seat 1. Meanwhile, the other side of the upper mold 3 rotates... The upper mold 3 is dynamically connected to the lifting plate 11. During mold opening, the upper seat 1 of the machine body rises, which in turn raises the lifting plate 11. The lifting plate 11 moves downward through the elongated hole 111 until the end of the elongated hole 111 abuts against the limiting bolt. Then, the lifting plate 11 raises the upper mold 3. During the raising process, the sliding sleeve 42 is subjected to an oblique pulling force, which causes the upper mold 3 to pull the lower mold 4 outside the machine body through the sliding sleeve 42 as it rises. At the same time, it rotates around the sliding sleeve 42 as the center, so that the upper mold 3 and the lower mold 4 open at a certain angle, which makes it convenient for the operator to pick up the product. In addition, in order to prevent the sliding sleeve 42 from disengaging from the mold lifting shaft 41, a limiting plate 43 is fixedly installed at the end of the mold lifting shaft 41 away from the lower mold 4.

[0024] The implementation principle of the non-powered mold opening structure of this utility model embodiment is as follows: When the mold is opened, the upper seat 1 of the machine body rises upward, and then drives the lifting plate 11 to rise. The lifting plate 11 moves downward through the elongated hole 111 until the end of the elongated hole 111 abuts against the limiting bolt. Then the lifting plate 11 drives the upper mold 3 to rise. During the process of the upper mold 3 rising, the sliding sleeve 42 is subjected to oblique pulling force, so that while the sliding sleeve 42 rises, the upper mold 3 pulls the lower mold 4 to move outside the machine body through the sliding sleeve 42. At the same time, it rotates around the sliding sleeve 42 as the center, so that the upper mold 3 and the lower mold 4 open at a certain angle. This makes it convenient for the operator to pick up the product, so that no additional power mechanism is needed to remove the mold and open the mold, simplifying the structure and reducing costs.
