Description

Technical Field

[0001] This utility model relates to the field of vulcanizing mold technology, specifically a quick-change mechanism for vulcanizing molds. Background Technology

[0002] Molds are indispensable in the rubber vulcanization process. Vulcanization molds are used for the vulcanization and molding of rubber products. They are usually made of metal and have a specific shape and structure, used to press the rubber material into the desired shape during vulcanization. Vulcanization molds play a crucial role in rubber product manufacturing, affecting the molding quality and appearance of the finished product. During the vulcanization process, impurities such as aged rubber and release agents adhere to the rubber molds, and the molds may also suffer scratches and impacts, affecting product quality. Therefore, frequent mold disassembly, cleaning, and maintenance are necessary. Traditional vulcanizing machines often use retaining rings or springs to fix the molds, which involves cumbersome disassembly and assembly procedures, high mechanical labor intensity, and long processing time. Utility Model Content

[0003] The purpose of this invention is to provide a quick disassembly and replacement mechanism for vulcanizing molds, which solves the problem of inconvenient quick disassembly and assembly of molds.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a quick-change mechanism for vulcanizing molds, comprising an upper template, an upper mounting hole inside the upper template, a through groove inside the upper template, an upper mold movably connected inside the through groove, an annular groove inside the through groove, an upper mold slidably fitted inside the annular groove, a spring pin fixedly installed inside the through groove, the spring pin engaging with the upper mold, a lower mold fixedly installed at the lower end of the upper mold, a lower template movably fitted outside the lower mold, and a lower mounting hole inside the lower template.

[0005] Preferably, there are multiple upper mounting holes, which are evenly distributed inside the upper template. These mounting holes allow for the connection and fixation of the upper template.

[0006] Preferably, there are multiple through slots, which are evenly distributed inside the upper mold plate. Designing multiple through slots facilitates the installation and use of multiple molds.

[0007] Preferably, there are multiple lower mounting holes, which are evenly distributed inside the lower template. Designing multiple lower mounting holes facilitates the installation and fixing of the lower template.

[0008] Preferably, the upper mold has a slot inside, the size of which is adapted to the spring pin. This slot design allows the spring pin to slide into the interior of the upper mold.

[0009] Preferably, the upper mounting hole and the lower mounting hole are positioned correspondingly.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention utilizes the design of an annular groove. When the upper mold is screwed into the through groove, the annular groove supports the upper mold and limits its vertical movement. Combined with the engagement of the spring pin and the internal slot of the upper mold, the upper mold and the upper template can be connected and fixed for use. Installation is convenient, and when the upper mold needs to be disassembled, simply rotate the upper mold to separate it from the annular groove and the spring pin, and then the upper mold can be pulled out from the upper template. This makes both assembly and disassembly of the mold convenient for use. Attached Figure Description

[0015] Figure 4 This utility model Figure 3 The right view of the structure.

[0016] In the diagram: When using the upper mold 4, first insert the upper mold 4 vertically into the through groove 3, then rotate the upper mold 4. The upper mold 4 will rotate inside the through groove 3. When the upper mold 4 rotates, it will slide into the annular groove 5. At this time, with the cooperation of the spring pin 6, the pin can be inserted into the matching slot opened inside the upper mold 4. At this time, the upper mold 4 can be locked, and the upper mold 4 and the upper template 1 can be installed and fixed for use.

[0017] When it is necessary to disassemble the upper mold 4, first separate the pin inside the spring pin 6 from the upper mold 4, then directly reverse the upper mold 4. The upper mold 4 slides inside the annular groove 5, so that the upper mold 4 can slide out from the annular groove 5 and be pulled out from the through groove 7. This makes it convenient to disassemble and assemble the mold, and also makes it convenient to clean and maintain the mold. Detailed Implementation

[0018] 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.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A quick-change mechanism for vulcanizing molds includes an upper template 1. Multiple upper mounting holes 2 are evenly distributed inside the upper template 1. These holes allow for connection and fixation of the upper template 1. Multiple through grooves 3 are also evenly distributed inside the upper template 1, facilitating the installation and use of multiple molds. An upper mold 4 is movably connected inside the through groove 3. An annular groove 5 is also provided inside the through groove 3, allowing the upper mold 4 to slide within it.

[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A spring pin 6 is fixedly installed inside the through groove 3. The spring pin 6 is engaged with the upper mold 4. The upper mold 4 has a slot inside, the size of which is adapted to the spring pin 6. By designing the slot, the spring pin 6 can slide into the interior of the upper mold 4. A lower mold 7 is fixedly installed at the lower end of the upper mold 4. A lower template 8 is movably sleeved on the outside of the lower mold 7. The lower template 8 has multiple lower mounting holes 9 inside. The multiple lower mounting holes 9 are evenly distributed inside the lower template 8. By designing multiple lower mounting holes 9, it is convenient to install and fix the lower template 8.

[0021] The specific implementation process of this utility model is as follows: When it is necessary to install the upper mold 4, first insert the upper mold 4 vertically into the through groove 3, then rotate the upper mold 4. The upper mold 4 will rotate inside the through groove 3. When the upper mold 4 rotates, the upper mold 4 will slide into the annular groove 5. At this time, with the cooperation of the spring pin 6, the pin can be inserted into the matching slot opened inside the upper mold 4. At this time, the upper mold 4 can be locked, and the upper mold 4 and the upper template 1 can be installed and fixed for use.

[0022] When it is necessary to disassemble the upper mold 4, first separate the pin inside the spring pin 6 from the upper mold 4, then directly reverse the upper mold 4. The upper mold 4 slides inside the annular groove 5, so that the upper mold 4 can slide out from the annular groove 5 and be pulled out from the through groove 3. This makes it convenient to disassemble and assemble the mold, and also makes it convenient to clean and maintain the mold.
