[0002] A mold is a set of molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to create shaped objects; this tool is composed of various parts, and different molds are composed of different parts. It primarily achieves the shaping of objects by changing the physical state of the material being molded.

[0003] In the process of precision mold machining, stable clamping of the mold is a key step to ensure machining accuracy and quality. Traditional mold clamping devices have many shortcomings. Conventional single-track drive structures are prone to mold displacement due to uneven force, which affects machining accuracy. Therefore, there is an urgent need for a stable clamping device for precision mold machining. Utility Model Content

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0013] First, this utility model uses a cylinder to drive the pusher and push rod to move the moving plate and clamping plate, thereby achieving the clamping of the precision module.

Detailed Implementation

[0020] 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.

[0021] This utility model provides the following technical solution:

[0022] Example 1

[0023] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A stable clamping device for precision mold processing includes a base 1, two first tracks 2 fixedly connected to the top of the base 1, a guide rod 3 installed on the top of the base 1, two sliding sleeves 4 slidably sleeved on the top of the guide rod 3, a movable plate 5 fixedly connected to the top of each of the two sliding sleeves 4, a clamping plate 6 fixedly connected to the top of each movable plate 5, two first sliders 7 fixedly connected to the bottom of each movable plate 5, and a drive assembly fixedly connected to the top of the base 1.

[0024] The drive assembly includes a bracket 8, a cylinder 9 is fixedly connected to the back of the bracket 8, a second rail 10 is fixedly connected to the bracket 8, a second slider 11 is slidably arranged on the second rail 10, a pusher 12 is fixedly connected to the top of the second slider 11, and two push rods 13 are hinged to the top of the pusher 12.

[0025] The output end of cylinder 9 is fixedly connected to push frame 12, and the end of each push rod 13 away from push frame 12 is hinged to moving plate 5.

[0026] Each first slider 7 is slidably mounted on the first track 2, and each clamping plate 6 has anti-slip texture on one side.

[0027] The base 1 is provided with a housing 14 on its top, and openings are provided on the top and rear sides of the housing 14 for the movement of the clamping plate 6 and the push rod 13.

[0028] Through the above technical solution, the base 1 has two first tracks 2 fixedly connected to its top, which provide a sliding path for the first slider 7. The guide rod 3 is fixed to the top of the base, and two sliding sleeves 4 are slidably fitted on its top. The sliding sleeves 4 can slide freely on the guide rod 3. The function of the sliding sleeves 4 is to provide guidance for the movement of the moving plate 5 and ensure the stability of the movement of the moving plate 5. The bottom of the moving plate 5 is fixedly connected to two first sliders 7, which are slidably set on the first tracks 2, so that the moving plate 5 can move smoothly along the first tracks 2. Each moving plate 5 has a clamping plate 6 fixedly connected to its top. The clamping plate 6 is used to directly clamp the mold, and one side of it is provided with anti-slip texture. To increase friction with the mold surface and prevent the mold from sliding during clamping, the drive assembly includes a bracket 8, a cylinder 9, a second track 10, a second slider 11, a pusher 12, and a push rod 13. The bracket 8 is fixed to the top of the base 1, providing support for the cylinder 9 and the second track 10. The output end of the cylinder 9 is fixedly connected to the pusher 12. When the cylinder 9 works, the extension and retraction of its output end will drive the pusher 12 to move. The second track 10 is fixed on the bracket 8. When the cylinder 9 pushes the pusher 12 to move, the push rod 13 will drive the moving plate 5 to slide on the first track 2, thereby causing the two clamping plates 6 to move closer or further apart, realizing the clamping and releasing operation of the mold.

[0029] Example 2

[0030] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 Furthermore, based on Embodiment 1, the following is obtained: a side rod 15 is fixedly connected to one end of each clamping plate 6, and a sliding groove is opened at the end of the two side rods 15 that are close to each other. A bidirectional lead screw 16 is rotatably arranged inside the sliding groove, and a clamping block 17 is threadedly connected to the surface of the positive and negative threads of each bidirectional lead screw 16.

[0031] Each clamping block 17 is slidably disposed in the slide groove, and the front of each bidirectional lead screw 16 passes through the clamping plate 6 and extends to its outside. A rotating handle is fixedly connected to the front of each bidirectional lead screw 16.

[0032] With the above technical solution, a side rod 15 is fixedly connected to one end of each clamping plate 6. A sliding groove is opened at the end of the two side rods 15 that are close to each other. The sliding groove provides space for the installation and movement of the bidirectional lead screw 16 and the clamping block 17. When the bidirectional lead screw 16 rotates, due to the action of its positive and negative threads, the two clamping blocks 17 will move closer or further away from each other in the sliding groove. By rotating the handle, the rotation of the bidirectional lead screw 16 can be easily controlled, thereby adjusting the distance between the two clamping blocks 17 and achieving more stable clamping of molds of different sizes.

[0033] In actual operation, when this device is in use, the mold is first placed between the two clamping plates 6, and then the cylinder 9 is activated. The output end of the cylinder 9 extends and pushes the pusher 12 to move along the second track 10. The movement of the pusher 12 drives the two moving plates 5 to slide towards each other on the first track 2 through the push rod 13, so that the two clamping plates 6 gradually approach the mold until the clamping plates 6 contact the mold surface and clamp the mold. The anti-slip texture on the clamping plates 6 prevents the mold from sliding. Then, by turning the handle, the bidirectional lead screw 16 is rotated, which drives the two clamping blocks 17 to move in the slide groove, further clamping the side of the mold and improving the stability and accuracy of clamping. When it is necessary to release the mold, the output end of the cylinder 9 retracts, which drives the pusher 12 to move in the opposite direction. The push rod 13 makes the two clamping plates 6 move away from each other. At the same time, the handle is turned to release the clamping blocks 17, and the mold can be taken out.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
