Description

Technical Field

[0001] This utility model belongs to the field of texturing technology, and in particular relates to a clamping fixture used for texturing models. Background Technology

[0002] Texture patterning is a surface treatment process for molds, also known as mold texturing, mold etching, or mold engraving. It is mainly used in the production of plastic products. The principle of texture patterning is to use chemical solutions to react with the mold steel. By controlling the reaction process, various texture effects can be obtained. During the texture patterning process, clamping fixtures are also needed to hold and position the mold.

[0003] Currently, commercially available texturing model clamping fixtures offer only a single clamping direction, lacking multi-directional clamping and positioning capabilities, and also lacking quick centering and positioning functions, thus affecting their usability. Therefore, there is an urgent need to improve existing texturing model clamping fixtures and provide a clamping fixture for texturing models that offers multi-directional clamping capabilities. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a clamping fixture for textured molds that is reasonably designed, simple in structure, easy to operate, has multi-directional clamping effect, and can quickly center and position the mold, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A clamping fixture for a textured pattern includes a support platform. Support legs are fixedly installed at the four right angles of the platform's bottom. Two first through slots are symmetrically formed at the center of the platform, each containing a bidirectional lead screw connected to a bearing on the platform. A servo motor is fixedly installed on the rear outer wall of the platform, with its output end fixedly connected to the rear end of the bidirectional lead screw. Two first clamping plates slide above the front and rear ends of the platform, respectively. Pushing components are provided on opposite sides of the two first clamping plates. Auxiliary clamping components are installed on the outer sides of both ends of the pushing components, and multiple sets of auxiliary clamping components are linked together.

[0007] Preferably, the pushing assembly includes a crossbar, a movable frame, a guide rod, and a spring. The crossbar is fixedly installed at the middle position of the two first clamping plates on opposite sides. The movable frame is slidably sleeved on the outer side of the crossbar. A spring is fixedly connected between the top of the movable frame and the first clamping plate. Guide rods are symmetrically fixedly installed on the left and right outer walls of the top of the movable frame.

[0008] Preferably, the bottom end of the movable frame is engaged and slidably located within the first through groove and threaded onto the outside of the bidirectional lead screw.

[0009] Preferably, the bottom end of the first clamping plate slides in contact with the upper end surface of the support platform, and the left and right ends of the first clamping plate are symmetrically provided with second through grooves, and a limit rod is fixedly connected to the inner side of each second through groove.

[0010] Preferably, the auxiliary clamping assembly includes a movable block, a first push rod, a second push rod, and a second clamping plate. The movable block is slidably sleeved on the outside of the guide rod. The bottom end of the movable block is hinged to the first push rod, and the other end of the first push rod is hinged to the first clamping plate. The upper end of the movable block is hinged to the second push rod, and the other end of the second push rod is hinged to the second clamping plate. The second clamping plate is slidably located in the second through groove and slidably sleeved on the outside of the limiting rod.

[0011] Preferably, the first push rod and the second push rod are of equal length and are arranged in a staggered symmetrical manner with respect to the movable block.

[0012] Preferably, the two second clamping plates located on the same first clamping plate are linked together and their sliding directions are always opposite.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, the mold is placed on the support platform, and then the servo motor is started and the bidirectional lead screw is controlled to rotate at a constant speed. Two movable frames can be used to control two sets of pushing components and two first clamping plates to move synchronously and slowly in the direction of mutual approach. The front and rear first clamping plates facilitate the initial centering and positioning of the mold.

[0015] This invention comes to rest after the first clamping plate comes into contact with the front and rear outer walls of the mold. At this time, the bidirectional lead screw continues to rotate, which can overcome the spring force and control the movable frame to move along the crossbar. This causes the movable frame and the guide rods fixed on both sides to gradually approach the first clamping plate. At this time, the first push rod and the second push rod can rotate and push the movable block to slide along the guide rod. This pushes the two second clamping plates on the left and right sides to move stably along the limit rod and approach each other. This can clamp and position the left and right sides of the mold, which not only facilitates multi-directional clamping of the mold, but also facilitates quick centering and positioning of the mold in the upper middle position of the support platform, which is convenient for subsequent texturing treatment.

Detailed Implementation

[0023] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0024] like Figure 1-4 As shown in the figure, the clamping fixture used in the texturing model of this utility model includes a support platform 1 and a first clamping plate 6. The support platform 1 is fixedly provided with support legs 2 at the four right angles of its bottom. Two first through slots 3 are symmetrically opened at the middle of the support platform 1. A bidirectional lead screw 4 is provided in the first through slot 3. The bidirectional lead screw 4 is connected to the bearing of the support platform 1. A servo motor 5 is fixedly installed on the outer wall of the rear end of the support platform 1. The output end of the servo motor 5 is fixedly connected to the rear end of the bidirectional lead screw 4. Two first clamping plates 6 are symmetrically arranged and slide on the upper part of the front and rear ends of the support platform 1. Pushing components 7 are provided on the opposite side of the two first clamping plates 6. Auxiliary clamping components 8 are installed on the outer side of the left and right ends of the pushing components 7. Multiple sets of auxiliary clamping components 8 are linked together.

[0025] Based on the above structure, the bottom end of the first clamping plate 6 slides against the upper end surface of the support platform 1, and the left and right ends of the first clamping plate 6 are symmetrically provided with second through grooves 9, and each second through groove 9 is fixedly connected to a limit rod 10 on its inner side.

[0026] In this embodiment, the second through groove 9 and the limiting rod 10 are used to facilitate the stable operation of the auxiliary clamping assembly 8.

[0027] Based on the above structure, the pushing component 7 includes a crossbar 71, a movable frame 72, a guide rod 73, and a spring 74. The crossbar 71 is fixedly installed at the middle position of the two first clamping plates 6 on opposite sides. The movable frame 72 is slidably sleeved on the outer side of the crossbar 71. The top of the movable frame 72 is fixedly connected to the first clamping plate 6 with a spring 74. The guide rods 73 are symmetrically fixedly installed on the outer walls of the top left and right sides of the movable frame 72.

[0028] Based on the above structure, the bottom end of the movable frame 72 is engaged and slidably located in the first through groove 3 and threaded onto the outside of the bidirectional lead screw 4.

[0029] In this embodiment, by controlling the rotation of the bidirectional lead screw 4, it is easy to control the two sets of pushing components 7 and the two first clamping plates 6 to move synchronously and slowly in the direction of mutual approach. The two first clamping plates 6 at the front and rear facilitate the initial centering and positioning of the mold.

[0030] Based on the above structure, the auxiliary clamping assembly 8 includes a movable block 81, a first push rod 82, a second push rod 83, and a second clamping plate 84. The movable block 81 is slidably sleeved on the outside of the guide rod 73. The bottom end of the movable block 81 is hinged to the first push rod 82, and the other end of the first push rod 82 is hinged to the first clamping plate 6. The upper end of the movable block 81 is hinged to the second push rod 83, and the other end of the second push rod 83 is hinged to the second clamping plate 84. The second clamping plate 84 is guided and slidably located in the second through groove 9 and slidably sleeved on the outside of the limiting rod 10.

[0031] Based on the above structure, the first push rod 82 and the second push rod 83 are of equal length and are arranged in a staggered symmetrical manner with respect to the movable block 81.

[0032] Based on the above structure, the two second clamping plates 84 located on the same first clamping plate 6 are linked together and their sliding directions are always opposite.

[0033] In this embodiment, when the first clamping plate 6 is stationary and the bidirectional lead screw 4 continues to rotate, the movable frame 72 can continue to move, and the guide rod 73 can continuously move closer to the first clamping plate 6. At this time, the first push rod 82 and the second push rod 83 can rotate, and push the movable block 81 to slide along the guide rod 73, which can push the two second clamping plates 84 on the left and right sides to move stably along the limiting rod 10 and move closer to each other, so as to clamp and position the left and right sides of the mold.

[0034] The working principle of this utility model is as follows:

[0035] In use, the mold to be textured is first placed on the support 1 and between the two first clamping plates 6. Then, the servo motor 5 is started to control the bidirectional lead screw 4 to start rotating. The two movable frames 72, which are threaded on the outside of the two threaded sections of the bidirectional lead screw 4, can drive the two sets of pushing components 7 and the two first clamping plates 6 to move synchronously in the same direction until the two first clamping plates 6 contact the front and rear sides of the mold, so as to achieve the initial centering and positioning of the mold.

[0036] When the two first clamping plates 6 come into contact with the front and rear sides of the mold and remain stationary, as the bidirectional lead screw 4 continues to rotate, it can overcome the elastic force of the spring 74, control the movable frame 72 to move along the cross bar 71, and make the guide rod 73 gradually approach the first clamping plate 6. At this time, the first push rod 82 and the second push rod 83 can be squeezed and rotated, and push the movable block 81 to slide along the guide rod 73, which can push the two second clamping plates 84 on the left and right sides to move stably along the limit rod 10 and approach each other, so as to clamp and position the left and right sides of the mold.

[0037] In summary, this clamping fixture, using two first clamping plates 6 and four second clamping plates 84, can clamp the mold in multiple directions from front to back and left to right. It also makes it easy to quickly center and position the mold in the upper middle position of the support table 1, which is convenient for subsequent texturing. It is simple to operate and highly efficient.

[0038] It should be noted that the power supply method and control means of the servo motor 5 are existing technologies and are not within the scope of innovation and improvement in this case, so they will not be described in detail.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
