[0002] Rubber strips are mainly used for sealing between connectors to prevent leakage of liquid or air, and molding modules are required during processing.

[0003] To process rubber strips with a diameter of about 1 meter, if a single mold is used, the mold diameter must also be over 1 meter to produce the rubber strip. Furthermore, different molds must be produced each time for rubber strips of different diameters, resulting in high costs. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a rubber strip segmented vulcanization molding die set without outer diameter limitation, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a segmented vulcanization molding die set for rubber strips without outer diameter limitation, comprising a lower molding die set, an upper molding die set, a splicing upper die set, and a splicing lower die set.

A pin is fixedly installed on the outer side of the moving column.

[0006] By adopting the above technical solution, the lower molding module and the upper molding module can be stably connected and positioned by using a pin and a square hole, ensuring that they will not easily separate. Furthermore, by setting up the upper and lower splicing modules, the two ends of the two rubber strips can be placed into the splicing groove, so that the ends of the two rubber strips are fused together as a whole, and the two rubber strips can be connected together to form a rubber strip with a large diameter.

[0007] In a preferred embodiment, the top of the frame is provided with a through groove that communicates with the mounting groove, and a guide block is fixedly installed on the top of the movable column, and the guide block is slidably installed on the inner wall of the through groove.

[0008] By adopting the above technical solution, the sliding of the guide block on the inner wall of the through groove can drive the moving column to move on the inner wall of the mounting groove, thereby achieving displacement.

[0009] In a preferred embodiment, a push plate is fixedly installed on the top of the guide block, and the bottom of the push plate is slidably connected to the top of the frame. The movable column is adapted to be slidably installed on the inner wall of the mounting groove.

[0010] By adopting the above technical solution, the pull plate can easily drive the guide block to move within the inner wall of the through groove, thereby simultaneously moving the position of the moving column and the pin.

[0011] In a preferred embodiment, the inner wall of the connecting plate is provided with a square hole, the square hole and the pin are positioned correspondingly, and the side of the pin away from the moving column is adapted to be inserted into the inner wall of the square hole.

[0012] By adopting the above technical solution, the upper molding module can be positioned by using the pin and square hole, ensuring that the upper molding module can be stably installed above the lower molding module. It also makes it easy to open the upper and lower molding modules to clean the inner wall of the molding groove, thus improving the convenience of assembly and splicing.

[0013] In a preferred embodiment, the number of the connecting plate, square hole, frame, spring, moving column, pin, guide block and push plate are all two, and the two connecting plates, square holes, frames, springs, moving columns, pins, guide blocks and push plates are symmetrically arranged, so that the two sides of the upper forming module can be positioned simultaneously, ensuring that the lower forming module and the upper forming module fit tightly after splicing.

[0014] In one preferred embodiment, the upper molding module is fitted onto the top of the lower molding module, and multiple molding grooves of different diameters are provided between the lower molding module and the upper molding module.

[0015] By adopting the above technical solution, it is possible to reassemble and combine rubber strips of different diameters without changing the lower and upper molding assemblies.

[0016] In a preferred embodiment, a docking post is fixedly installed on the top of the lower forming module, and a docking hole is opened on the inner wall of the upper forming module, with the docking post inserted into the inner wall of the docking hole.

[0017] By adopting the above technical solution, the positional accuracy of the connection and assembly between the lower molding module and the upper molding module can be improved, ensuring that no positional shift will occur after installation.

[0018] In a preferred embodiment, both the upper and lower splicing modules have splicing grooves on their inner walls.

[0019] By adopting the above technical solution, multiple rubber strips can be spliced ​​together to form a rubber strip with a large diameter.

[0020] The beneficial effects of this application are:

[0021] This is a segmented vulcanization molding die set for rubber strips without outer diameter limitations. By pushing the push plate, the guide block can be easily moved to the inner wall of the through groove, and the positions of the moving column and the pin can be moved simultaneously. The upper molding die can be removed from the top of the lower molding die, which is convenient for handling rubber strips of different diameters. It is also convenient to open the upper molding die and the lower molding die for cleaning. This solves the problem of high cost in existing devices that require the production of different molds for rubber strips of different diameters each time.

Detailed Implementation

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0030] Reference Figure 1-5A segmented vulcanization molding die set for rubber strips without outer diameter limitation includes a lower molding die 1, an upper molding die 2, a splicing upper die 15, and a splicing lower die 16. A molding groove 3 is formed in the middle of the lower molding die 1 and the upper molding die 2. A connecting plate 5 is fixedly installed on the outer side of the lower molding die 1. A frame 7 is fixedly installed on the top of the upper molding die 2. An installation groove 8 is formed on the inner wall of the frame 7. One end of a spring 10 is fixedly connected to the inner wall of the installation groove 8. A moving column 11 is fixedly connected to the other end of the spring 10. A pin 12 is fixedly installed on the outer side of the moving column 11, allowing the pin 12 to be used in conjunction with a square hole 6 to securely connect and position the lower molding die 1 and the upper molding die 2, ensuring they do not easily detach. Furthermore, by setting up the splicing upper die 15 and the splicing lower die 16, the two ends of two rubber strips can be placed into the splicing groove 17, fusing the ends of the two rubber strips into a whole, thereby connecting the two rubber strips together to form a rubber strip with a large diameter.

[0031] See Figure 3 The top of the frame 7 is provided with a through groove 9, which is connected to the mounting groove 8. A guide block 13 is fixedly installed on the top of the movable column 11, and the guide block 13 is slidably installed on the inner wall of the through groove 9, so that the guide block 13 can slide on the inner wall of the through groove 9 to drive the movable column 11 to move on the inner wall of the mounting groove 8, thereby achieving displacement.

[0032] See Figure 3 A push plate 14 is fixedly installed on the top of the guide block 13, and the bottom of the push plate 14 is slidably connected to the top of the frame 7. The moving column 11 is adapted to be slidably installed on the inner wall of the mounting groove 8, so that pulling the push plate 14 can easily drive the guide block 13 to move on the inner wall of the through groove 9, thereby simultaneously moving the positions of the moving column 11 and the pin 12.

[0033] See Figure 3 and Figure 4 The inner wall of the connecting plate 5 is provided with a square hole 6, and the square hole 6 and the pin 12 are positioned correspondingly. The side of the pin 12 away from the moving column 11 is adapted to be inserted into the inner wall of the square hole 6, so that the pin 12 can be used in conjunction with the square hole 6 to position the upper molding module 2, ensuring that the upper molding module 2 can be stably installed above the lower molding module 1, and making it easy to open the upper molding module 2 and the lower molding module 1 to clean the inner wall of the molding groove 3, thus improving the convenience of assembly and splicing.

[0034] See Figure 1 - Figure 4The number of connecting plate 5, square hole 6, frame 7, spring 10, moving column 11, pin 12, guide block 13 and push plate 14 are all two, and the two connecting plates 5, square hole 6, frame 7, spring 10, moving column 11, pin 12, guide block 13 and push plate 14 are symmetrically arranged, so that the two sides of the upper molding module 2 can be positioned simultaneously, ensuring that the lower molding module 1 and the upper molding module 2 fit tightly after splicing.

[0035] See Figure 1 and Figure 2 The upper molding module 2 is fitted and installed on the top of the lower molding module 1. Multiple molding grooves 3 of different diameters are set in the middle of the lower molding module 1 and the upper molding module 2, so that when processing rubber strips of different diameters, there is no need to replace different lower molding modules 1 and upper molding modules 2. They can be reassembled and reassembled. It is also convenient to open the lower molding module 1 and the upper molding module 2 for cleaning.

[0036] See Figure 2 The lower molding module 1 is fixedly installed with a docking post 4, and the inner wall of the upper molding module 2 is provided with a docking hole. The docking post 4 is inserted into the inner wall of the docking hole, which can improve the positional accuracy of the connection and assembly between the lower molding module 1 and the upper molding module 2, and ensure that no positional shift will occur after installation.

[0037] See Figure 1 and Figure 5 Both the upper module 15 and the lower module 16 have splicing grooves 17 on their inner walls, which allows multiple rubber strips to be spliced ​​together to form a rubber strip with a large diameter.

[0038] Working principle: When using this device, the push plate 14 can be pulled to easily move the guide block 13 to the inner wall of the through groove 9, and then the positions of the moving column 11 and the pin 12 can be moved simultaneously. At this time, the spring 10 is under force, and the pin 12 can be moved away from the inner wall of the square hole 6. Then the upper molding module 2 can be removed from the top of the lower molding module 1, so as to facilitate the handling of different rubber strips.

[0039] Then, the two ends of the two rubber strips can be placed into the splicing grooves 17 inside the splicing upper module 15 and the splicing lower module 16, so that the two rubber strips can be connected together to form a rubber strip with a large diameter.
