Description

Technical Field

[0001] This utility model belongs to the field of rubber processing and relates to rubber demolding technology, specifically a tooling for a rubber cable ring demolding device. Background Technology

[0002] Demolding refers to the process of removing a rubber product from a mold after it has been formed in the mold through processes such as vulcanization.

[0003] For some irregularly shaped rubber rings, demolding mainly involves operators manually peeling the movable diaphragm from the mold, and then separating the product from the mold through the demolding nozzle. However, when manually peeling the movable diaphragm, it is difficult to ensure that the force applied to the diaphragm is consistent. If the applied force is uneven, the rubber product may be subjected to uneven stretching or compression during demolding, resulting in cracks and reducing the product's pass rate. This process requires a high level of skill from the operators. Furthermore, during demolding, it is necessary to observe whether the diaphragm in each cavity has peeled off and moved into place, and the observation time is difficult to control, which can easily cause the mold to cool down, increasing the difficulty of subsequent product peeling.

[0004] Therefore, this utility model proposes a tooling for a rubber cable ring demolding device. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a rubber ring demolding fixture, which solves the problem that existing methods for manually demolding some irregularly shaped rubber rings require high technical skills from operators and are difficult to control the time of detachment from the movable mold, thus affecting subsequent operations.

[0006] To achieve the above objectives, a rubber band release device tooling is provided according to an embodiment of the first aspect of this utility model, comprising:

[0007] The base plate and two cylinders are slidably mounted on the base surface and the two cylinders are symmetrically fixed on the base surface. The base plate and the cylinders are detachably connected.

The surface of each drive block has a fitting groove, the cross-section of which is U-shaped, and the dimension of the fitting groove on the side away from the crossbeam is smaller than the dimension on the side closer to the crossbeam. The crossbeams are inclined relative to the base plate and the drive blocks.

[0009] A core assembly is detachably connected to a crossbeam. The core assembly includes a movable diaphragm and a guide block. The guide block is detachably connected to the crossbeam.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figure 1-4 As shown, a rubber ring demolding tooling includes a base plate 1, two cylinders 2, a mold core assembly, and a drive assembly;

[0024] The base plate 1 is slidably mounted on the surface of the base, and a connecting groove 7 is provided on the surface of the base plate 1;

[0025] Two cylinders 2 are symmetrically fixedly mounted on the base surface. One end of the piston rod inside each cylinder 2 is fixedly connected to a connecting block 8, and the connecting groove 7 is adapted to the connecting block 8.

[0026] The driving assembly includes several driving blocks 3 and a crossbeam 4. The driving blocks 3 are all fixedly connected to the base plate 1, and the crossbeam 4 is detachably connected to the base. The distance between the driving blocks 3 and the crossbeam 4 is equal. The surface of the driving blocks 3 is provided with a fitting groove. The cross-section of the fitting groove is U-shaped, and the dimension of the fitting groove on the side away from the crossbeam 4 is smaller than the dimension on the side closer to the crossbeam 4. The crossbeam 4 is inclined relative to the base plate 1 and the driving blocks 3.

[0027] The mold core assembly includes a movable diaphragm 5 and a guide block 6. The guide block 6 is detachably connected to the crossbeam 4. The movable diaphragm 5 is slidably connected to the side of the guide block 6 away from the crossbeam 4. The number of guide blocks 6 is equal to the number of driving blocks 3. The movable diaphragm 5 is adapted to the fitting groove. Thus, the mold core assembly can be fixed between the driving blocks 3 and the crossbeam 4, and is relatively fixed to the base plate 1. The product is formed on the side of the movable diaphragm 5 away from the guide block 6. After the product is formed, the base plate 1 can be driven to slide by the cylinder 2. The sliding of the base plate 1 causes all the driving blocks 3 to slide synchronously, which in turn causes the movable diaphragm 5 to slide. Since the sliding speed of the base plate 1 is equal, the force applied by the driving blocks 3 to the movable diaphragm 5 remains unchanged, reducing the possibility of cracks in the product. Moreover, the speed can be directly controlled by the cylinder 2 to ensure that the surface of the mold core assembly is not completely cooled, which facilitates subsequent removal.

[0028] In practical application, this rubber ring demolding fixture initially positions the movable diaphragm 5 in the mold via guide block 6 and driving block 3. Guide block 6 is fixed to the base via crossbeam 4, and driving block 3 is connected to cylinder 2 via base plate 1, thereby driving block 3 to slide. With guide block 6 fixed in position, the movement of driving block 3 can directly change the position of movable diaphragm 5, realizing the separation of movable diaphragm 5 from the product. Furthermore, the force applied by cylinder 2 to move movable diaphragm 5 ensures the balance of forces on all driving blocks 3 and controls the time of separation between movable diaphragm 5 and product, ensuring the rapid progress of subsequent demolding processes; further improving product qualification rate and reducing the time required for product production.

[0029] In some specific implementations, the aforementioned driving component further includes two positioning posts 9, which are symmetrically arranged relative to the center line of the crossbeam 4. Each positioning post 9 is fixedly connected to the base by a screw. An insertion rod 10 is fixedly connected to the side of the positioning post 9 near the crossbeam 4. A through groove 11 is formed on the surface of the crossbeam 4, and the insertion rod 10 is adapted to the through groove 11. By raising the position of the crossbeam 4 relative to the base through the positioning posts 9, it is ensured that after the guide block 6 is fixed to the crossbeam 4, the movable diaphragm 5 is in a horizontal state, ensuring smooth movement of the movable diaphragm 5. Moreover, the crossbeam 4 can be disassembled by directly raising it, and the mold core assembly can be easily removed after the irregular rubber ring is formed.

[0030] In a further embodiment, an arc-shaped groove 12 is provided on the side of the base plate 1 away from the cylinder 2, and the arc-shaped groove 12 is adapted to the positioning post 9; by providing an arc-shaped groove 12 on the side of the base plate 1 away from the cylinder 2 to fit against the positioning post 9, the sliding distance of the base plate 1 can be limited by the position of the positioning post 9.

[0031] In some specific implementations, two sliding blocks 13 are fixedly connected to the side of the base plate 1 away from the driving block 3. The two sliding blocks 13 are symmetrically arranged. A slide rail 14 is fixedly connected to the surface of the base. The sliding blocks 13 are adapted to the slide rail 14.

[0032] In some specific implementations, the surface of the crossbeam 4 is provided with a plurality of positioning grooves 15, the positioning grooves 15 including threaded grooves and horizontal grooves, the horizontal grooves being adapted to the guide block 6, the surface of the guide block 6 being provided with an insertion groove 16, the insertion groove 16 being the same size as the threaded groove, and after the guide block 6 is completely slid into the horizontal groove, the insertion groove 16 is aligned with the threaded groove; the threaded grooves on the surface of the crossbeam 4 and the insertion grooves 16 on the surface of the guide block 6 are used to fix the positions of the guide block 6 and the crossbeam 4, and restrict the position of the movable diaphragm 5 on one side of the guide block 6, which facilitates the quick installation of the mold core assembly;

[0033] The working principle of this utility model is as follows: First, the guide block 6 is inserted into the crossbeam 4. Then, the through groove 11 of the crossbeam 4 corresponds to the insertion rod 10 of the positioning column 9. The insertion rod 10 is inserted into the through groove 11 to fix the position of the crossbeam 4. Then, the base plate 1 is pushed to slide by the control cylinder 2, so that the surface of the driving block 3 contacts the movable diaphragm 5. Then, the base plate 1 is retracted towards the position of the cylinder 2. The sliding of the base plate 1 causes the driving block 3 to slide. At this time, the sliding of the driving block 3 will cause the movable diaphragm 5 to slide on the surface of the guide block 6. After the movable diaphragm 5 slides and demolds the product from the mold, the product can be blown out through the blown nozzle.

[0034] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
