Description

Technical Field

[0001] This utility model relates to the field of nitrile rubber processing technology, and in particular to a segmented vulcanization equipment for nitrile rubber. Background Technology

[0002] The mixed compound rubber is poured into a mold on a vulcanizing machine, and then the mold is placed inside the vulcanizing machine. Vulcanization is achieved under pressure conditions of 120-200°C and below 15 bar. The mold and pressing device mainly provide uniform pressure to ensure the nitrile rubber maintains its shape during vulcanization and avoids defects such as air bubbles. The mold can be changed according to the different shapes of the rubber products as needed.

[0003] In the prior art, Chinese patent application number 202222317566.X discloses a segmented vulcanization equipment for nitrile rubber. Addressing the problem that in existing vulcanization equipment, after the rubber is vulcanized, manual demolding is generally required, which is time-consuming and labor-intensive. Manual operation not only increases the labor intensity of personnel but also reduces work efficiency, and manual demolding easily damages the molded rubber after vulcanization. The proposed solution includes a base plate, with the equipment body fixedly connected to the top of the base plate. Two electric slide rails are fixedly connected to the top of the base plate, and a single mold is slidably connected to one side of the two electric slide rails that are close to each other. The bottom of the mold slides in contact with the top of the base plate. This utility model achieves automated and rapid demolding of rubber through a simple structure, eliminating the need for manual operation, reducing the labor intensity of personnel, and avoiding the problem of rubber damage caused by manual demolding. It is highly practical.

[0004] However, the above-mentioned technical solutions have molds installed on two electric slide rails, which makes it inconvenient to replace the molds, has poor applicability, and is not convenient for vulcanizing different rubber product shapes, thus failing to meet the usage requirements. Therefore, this application proposes a segmented vulcanizing equipment for nitrile rubber to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the mold being installed on two electric slide rails, which makes mold replacement inconvenient, has poor applicability, and is not suitable for vulcanizing different shapes of rubber products, thus failing to meet usage requirements. Therefore, this invention proposes a segmented vulcanizing equipment for nitrile rubber.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A segmented vulcanizing device for nitrile rubber includes a base plate, and the vulcanizing device further includes:

[0008] Two electric slide rails are provided, both of which are fixedly installed on the top of the base plate, and the same mounting plate is slidably installed on the top of the two electric slide rails.

[0009] The mold is placed on top of the mounting plate, and a rectangular rod is fixedly installed at the bottom of the mold. The bottom end of the rectangular rod passes through the mounting plate and is slidably connected to the mounting plate. The front and rear sides of the rectangular rod are provided with slots.

[0010] The device includes two locking levers, the top ends of which are slidably connected to the bottom of the mounting plate. A second spring is fixedly installed on the side of the two locking levers that is far apart from each other. The ends of the two second springs that are far apart from each other are fixedly installed on the bottom of the mounting plate.

Beneficial effects

[0018] 1. By passing the rectangular rod at the bottom of the mold through the mounting plate, the mold can be placed on top of the mounting plate. At the same time, the bottom end of the rectangular rod can press the two locking rods away from each other. Then, when the bottom of the mold contacts the top of the mounting plate, the elastic return characteristic of the second spring can drive the two locking rods to move closer together and lock into the two locking slots. At this time, the rectangular rod, the mold, and the mounting plate can be locked together. In addition, by pushing the unlocking rod, the two transmission rods can be moved upward and press the two locking rods away from each other, thus releasing the locking rods from the locking slots. This allows for easy disassembly of the rectangular rod and the mold. This method enables quick assembly and disassembly of the mold, so that the appropriate mold can be used to replace the mold according to the shape of the nitrile rubber to be vulcanized.

[0019] 2. The attraction between the second electromagnet and the first electromagnet ensures the stability of the insertion between the rod and the tube, thereby improving the installation stability of the electric heating plate and facilitating the disassembly of the electric heating plate.

[0020] 3. By activating the electric push rod, the lifting plate, insertion tube, electric heating plate and insertion rod can be raised and lowered. When the electric heating plate moves down, it can work with the mold to heat and press the nitrile rubber inside, and at the same time realize the vulcanization process.

[0021] This invention enables quick assembly and disassembly of the mold and electric heating plate through a simple structure. It allows for the replacement of the appropriate mold with one that matches the shape of the nitrile rubber to be vulcanized, and the operation is time-saving and labor-saving, thus improving the applicability and practicality of the vulcanization equipment.
