Description

Technical Field

[0001] The utility model relates to the technical field of guide rail locks, in particular to a guide rail lock for the tread ring of a molding machine. Background Technique

[0002] A molding machine is an industrial device used to manufacture various parts and products. It processes raw materials through a mold to achieve a specific shape and size. When manufacturing tires, a molding machine usually uses a tread ring. The tread ring of a molding machine is a key component in the tire manufacturing process. It is usually used to form the tread part of the tire, enabling the tire to obtain the required shape and pattern. To ensure the stable and accurate position of the tread ring during the molding process, a guide rail lock is usually used for locking.

[0003] During the working process, the tread ring usually needs to grab the tread, so that the tread composite can be smoothly transferred to the molding drum through the tread ring to form a tire blank. The main way of grabbing is to use a cylinder to provide the power and structure for grabbing. During the transfer of the tread, it is transmitted in the form of a cylinder. Since its axial force is borne by the guide rod and the linear bearing connecting the guide rods, the force it can bear is small. This will cause the cylinder and the guide rod to deform due to too large axial force when taking the tread composite or replacing the tile, resulting in the cylinder being unable to retract and causing damage to the components. It may also cause the tile to become loose and unstable, resulting in deviation during the transfer of the tread composite and affecting the quality. Therefore, the actual use effect is poor. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a guide rail lock for the tread ring of a molding machine, aiming to improve the problems in the prior art that due to the small bearing force, it is easy to cause damage to components due to the inability of the cylinder to retract and deviation during the transfer of the tread composite.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: A guide rail lock for the tread ring of a molding machine includes a U-shaped plate. The middle parts of the two side walls and the two sides of the rear wall of the U-shaped plate are fixedly connected with slide rails.

The bottom ends of the two limit rods penetrate through the bottom wall of the connecting block and are fixedly connected to the inner bottom wall of the moving block, and the two springs are arranged on the outer periphery of the limit rods.

[0018] Through the above technical solution, the stability of the movement of the connecting block can be ensured and the springs can be prevented from bending when compressed.

[0032] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0033] Refer to Figure 1 、 Figure 2 andFigure 5 An embodiment provided by the present utility model: A tread ring guide lock for a molding machine, comprising a U-shaped plate 1. Slide rails 2 are fixedly connected to the middle parts of the two side walls and both sides of the rear wall of the U-shaped plate 1. Sliders 14 are slidably connected to the outer peripheries of the slide rails 2 on both sides and one side of the rear wall. A clamp 19 is slidably connected to the outer periphery of the slide rail 2 on the other side of the rear wall. A rear support plate 4 is fixedly connected to the rear walls of the rear slider 14 and the clamp 19. Side support plates 5 are fixedly connected to the outer sides of the two sliders 14 away from each other. A lower support plate 6 is fixedly connected to the lower parts of the two side support plates 5 close to each other. A cylinder 11 is arranged in the middle of the top wall of the lower support plate 6, and the output end of the cylinder 11 is arranged on the inner top wall of the U-shaped plate 1;

[0034] Specifically, by starting the cylinder 11, the U-shaped plate 1 can be driven to expand and contract through the output end, so that the U-shaped plate 1 will move up and down along the slider 14 through the slide rail 2. By using the U-shaped plate 1 as a carrier, the U-shaped plate 1 is connected to the tile and the spacer, and then the slider 14 is used as a sliding element and a stress point, so that the force on the tile in the axial direction is greatly increased. And the clamp 19 is used as a fixing part, so that the tile will not slide, so that the tread composite can be correctly transmitted. And by adopting the slider 14 and the guide rail structure in three directions, the force that a single tread ring tile can bear in the axial and radial directions exceeds 1600N, greatly reducing the grasping deviation, instability and other equipment failures caused by large axial force during the grasping and transmission process.

[0035] Refer to Figure 1 、 Figure 3 and Figure 4 , a clamping groove 12 is opened in the middle of the inner top wall of the U-shaped plate 1. A clamping block 13 is fixedly connected to the output end of the cylinder 11. The clamping block 13 is slidably connected in the clamping groove 12. A moving groove 8 is opened in the front of the middle of the top wall of the lower support plate 6. A moving block 9 is slidably connected in the moving groove 8. Springs 17 are fixedly connected to the front and rear sides of the inner bottom wall of the moving block 9. The top ends of the two springs 17 are fixedly connected to a connecting block 16. An abutting block 10 is fixedly connected to the top wall of the connecting block 16. The top end of the abutting block 10 penetrates through the top wall of the moving block 9; The clamping groove 12 is a T-shaped groove, and the clamping block 13 is a T-shaped block; Limiting rods 15 are fixedly connected to the front and rear sides of the inner top wall of the moving block 9. The bottom ends of the two limiting rods 15 penetrate through the bottom wall of the connecting block 16 and are fixedly connected to the inner bottom wall of the moving block 9. The two springs 17 are both arranged on the outer periphery of the limiting rod 15;

[0036] Specifically, by pressing the abutting block 10 to retract it into the moving block 9, the abutting limit between the abutting block 10 and the cylinder 11 can be cancelled. Subsequently, the staff can remove the cylinder 11 from the lower support plate 6. When the cylinder 11 needs to be installed, only need to push the clamping block 13 along the clamping groove 12. Since both the clamping block 13 and the clamping groove 12 are T-shaped, the cooperation of the clamping block 13 and the clamping groove 12 can limit the cylinder 11 up and down and can push the U-shaped plate 1 to move along with the output end of the cylinder 11. When the cylinder 11 is pushed into the device, the cylinder 11 will contact the abutting block 10 and squeeze the abutting block 10. When the abutting block 10 is pressed, it will move downward and compress the spring 17 through the connecting block 16. After the cylinder 11 is completely pushed into the device, under the action of the spring 17, the abutting block 10 can be reset and the cylinder 11 can be abutted and limited and fixed, so as to achieve the effect of facilitating the installation, disassembly and replacement of the cylinder 11. At the same time, under the action of the limiting rod 15, the connecting block 16 can be limited, ensuring the stability of the movement of the connecting block 16 and preventing the spring 17 from bending when being pressed.

[0037] Referring to Figure 1 , Figure 4 and Figure 5 , connecting plates 3 are fixedly connected to the outer sides of the two side support plates 5 away from each other and the rear wall of the rear support plate 4; the rear wall of the moving groove 8 is rotatably connected with a threaded rod 18, and the front end of the threaded rod 18 sequentially passes through the moving block 9 and the front wall of the lower support plate 6 and is fixedly connected with a knob 7;

[0038] Specifically, by providing the connecting plate 3, the device can be fixed on the tread ring; by providing the threaded rod 18, when the knob 7 is rotated, the threaded rod 18 can be driven to rotate, so that the moving block 9 can be driven to move along the threaded rod 18, thereby being able to adjust the position of the abutting block 10 to make it suitable for fixing cylinders 11 of different specifications.

[0039] Working principle: By starting the cylinder 11, the U-shaped plate 1 can be driven to expand and contract through the output end, so that the U-shaped plate 1 will move up and down along the slide block 14 through the slide rail 2. By using the U-shaped plate 1 as a carrier, the U-shaped plate 1 is connected to the tile and the cushion block, and then the slide block 14 is used as a sliding element and a stress point, so that the force on the tile in the axial direction is greatly increased, and the clamp 19 is used as a fixing part to prevent the tile from sliding, so that the tread composite can be correctly transmitted, and thus the grasping deviation, instability and other equipment failures caused by the large axial force during the grasping and transmission process are greatly reduced; in addition, by pressing the abutting block 10 to retract it into the moving block 9, the limit with the cylinder 11 can be cancelled, and then the staff can remove the cylinder 11 from the lower support plate 6. When the cylinder 11 needs to be installed, only the clamping block 13 needs to be pushed along the card slot 12, and the cylinder 11 will contact and squeeze the abutting block 10. After the cylinder 11 is completely pushed into the device, the abutting block 10 can be reset and abut against the cylinder 11 for limit fixation under the action of the spring 17, so as to achieve the effect of facilitating the installation, disassembly and replacement of the cylinder 11.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
