Description

Technical Field

[0001] This utility model relates to the field of clamping fixture technology, and more specifically, to a clamping fixture for tire mold components. Background Technology

[0002] In the manufacturing process of tire molds, clamping fixtures are key equipment to ensure the machining accuracy and quality of mold components. As tire mold designs become increasingly complex and diverse, the performance requirements for clamping fixtures are also becoming higher.

[0003] Traditional clamping fixtures for tire mold components have many drawbacks. Some fixtures use a single positioning method, making it difficult to adapt to tire mold components of different shapes and sizes. Inaccurate positioning is prone to occur during clamping, resulting in the finished mold components failing to meet production requirements in terms of precision. For example, some simple fixtures rely solely on fixed slots or clamping blocks for positioning, which cannot achieve tight fit and precise positioning for irregularly shaped tire mold components.

[0004] Furthermore, traditional fixtures lack sufficient clamping force and stability. During machining, mold components are subjected to external forces such as cutting forces and impact forces. If the fixture cannot provide sufficient clamping force, the components are prone to loosening and displacement, which not only affects machining accuracy but may also damage the cutting tools and even cause safety accidents. In addition, some existing fixtures are cumbersome to operate, and the clamping and disassembly processes are time-consuming. When frequent changes of mold components are required for machining, this will greatly reduce production efficiency and increase production costs.

[0005] Therefore, a clamping fixture for tire mold components is proposed. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a clamping fixture for tire mold components to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a tire mold component clamping fixture, including a fixing plate, wherein a plurality of through slots are provided on the fixing plate, a moving component is installed at the bottom of each through slot, and a pressure fixing component is installed on each moving component.

[0008] By placing the tire mold component on the fixed plate, each clamping component is pre-opened at a certain angle according to the shape of the tire mold component. Each moving component operates separately, causing the corresponding clamping component to move separately. First, the tire mold component is pushed and positioned. After positioning, the clamping component moves down to clamp the tire mold component, thereby fixing the tire mold component. This not only positions the tire mold component but also clamps it according to its shape, thus improving the clamping stability.

[0009] Preferably, the moving component includes a motor, a screw, a slide rail, and a slide base. The motor is mounted on the bottom of the fixed plate, and the output end of the motor is connected to the screw. Slide rails are provided on both sides of the screw. The slide base is sleeved on the screw and has two slide rails slidably connected to it. The clamping component is mounted on the slide base.

[0010] Preferably, a plurality of bearing seats are installed at the bottom end of the fixing plate, and each bearing seat is connected to the corresponding end of the screw.

[0011] Preferably, the slide has two through holes, a bracket is provided on one side of the through holes, and a shaft is installed on the bracket.

[0012] Preferably, the clamping assembly includes a dual-axis cylinder, a rotating rod, and a pressure plate. The dual-axis cylinder is installed at the bottom of the slide block, and the two shafts of the dual-axis cylinder pass through through holes and are connected to the rotating rod. The pressure plate is installed on the shaft, and one end of the pressure plate is slidably connected to the rotating rod.

[0013] Preferably, one end of the pressure plate has a sliding groove, and the rotating rod is inserted into the sliding groove.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. By working together with the moving and clamping components, the parts are pushed, positioned and clamped, which improves the stability of the clamping and ensures that the parts will not be displaced during processing, thus guaranteeing processing accuracy.

[0016] 2. The screw is driven to rotate by the motor in the moving component, so that the slide block moves along the slide rail. The distance between the clamping component and the tire mold component can be flexibly adjusted to meet the clamping requirements of components of different sizes.

[0017] 3. By supporting the screw with the bearing seat at the bottom of the fixed plate, the shaking when the motor drives the screw to rotate is reduced, the stability of the screw is improved, and the smoothness and accuracy of the slide movement are enhanced, making the clamping operation more precise and reliable.

[0018] 4. Through the design of the dual-axis cylinder, rotating rod and pressure plate of the clamping assembly, the pressure plate can swing up and down according to the operation of the dual-axis cylinder, which can adapt to tire mold parts of different shapes and achieve tight clamping.

[0024] 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.

[0025] As attached Figures 1-4 The tire mold component clamping fixture shown includes a fixing plate 1, on which a plurality of through slots 2 are provided. A moving component 3 is installed at the bottom of each through slot 2, and a pressure fixing component 4 is installed on each moving component 3.

[0026] In practice, the tire mold component is placed on the fixed plate 1. Each clamping component 4 is pre-opened at a certain angle according to the shape of the tire mold component. Each moving component 3 operates separately, causing the corresponding clamping component 4 to move separately. First, the tire mold component is pushed and positioned. After positioning, the clamping component 4 moves down to clamp the tire mold component, thereby fixing the tire mold component. This not only allows for positioning of the tire mold component, but also allows for clamping and holding according to the shape of the tire mold component, thereby improving the stability of the clamping.

[0027] The moving component 3 includes a motor 301, a screw 302, a slide rail 303, and a slide base 304. The motor 301 is mounted on the bottom of the fixed plate 1. The output end of the motor 301 is connected to the screw 302. Slide rails 303 are provided on both sides of the screw 302. The slide base 304 is sleeved on the screw 302, and the slide base 304 has two slide rails 303 slidably connected. The pressing component 4 is mounted on the slide base 304.

[0028] In practice, the operation of motor 301 enables screw 302 to rotate, thereby allowing slide 304 to move along slide rail 303, thus adjusting the distance between the pressing assembly 4 and the tire mold component placed on the fixed plate 1.

[0029] The bottom end of the fixing plate 1 is equipped with multiple bearing seats, and each bearing seat is connected to the end of the corresponding screw 302.

[0030] In practice, the end of the screw 302 is supported by the bearing, so that when the motor 301 drives the screw 302 to rotate, the screw 302 can be prevented from shaking, thus improving the stability of the screw 302. This makes the movement of the slide 304 smoother and improves the movement accuracy of the slide 304.

[0031] The slide block 304 has two through holes 6, and a bracket 5 is provided on one side of the through hole 6, and a shaft 7 is installed on the bracket 5.

[0032] The pressure assembly 4 includes a dual-axis cylinder 401, a rotating rod 402, and a pressure plate 403. The dual-axis cylinder 401 is installed at the bottom of the slide block 304, and the two shafts of the dual-axis cylinder 401 pass through the through hole 6 and are connected to the rotating rod 402. The pressure plate 403 is installed on the shaft 7, and one end of the pressure plate 403 is slidably connected to the rotating rod 402.

[0033] The pressure plate 403 has a sliding groove at one end, and the rotating rod 402 is inserted into the sliding groove.

[0034] In practice, the height of the rotating rod 402 can be adjusted by the operation of the dual-axis cylinder 401. When the height of the rotating rod 402 changes, one end of the pressure plate 403 can be pushed or pulled, and the rotating rod 402 moves relative to the slide groove, so that the other end of the pressure plate 403 can swing up and down under the support of the shaft 7. When the end of the pressure plate 403 connected to the tire mold component descends, the tire mold component can be pressed down, thereby achieving clamping and fixing.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
