Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a clamping device for processing plastic molds. Background Technology

[0002] A plastic mold is a specialized tool used to mold plastic products. It enables the mass production of plastic products in a high-efficiency and precise manner by giving plastic specific shapes, sizes and properties.

[0003] Patent application publication number CN211027818U discloses a plastic mold device for easy part removal. It includes a mold base with supporting feet fixedly connected to its bottom. An electric telescopic rod is fixedly connected to the inner side of the mold base. Using this patent, the stamped plastic mold is moved above the fixed mold. Two electric push rods can drive two clamping blocks to move relative to each other, thus clamping the processed plastic mold. However, the clamping blocks in the aforementioned prior art are of a fixed shape. If the product has a different shape, the clamping blocks cannot effectively clamp it and are difficult to perfectly fit the surface of different products.

[0004] In view of the existing patents, there is a need to provide a clamping device for processing plastic molds that can adapt to various shapes. Utility Model Content

[0005] In order to overcome the shortcomings of the existing patents, where the clamping blocks are of a fixed shape and cannot effectively clamp products with different shapes, and are difficult to fully fit the surfaces of different products, this utility model provides a clamping device for processing plastic molds that can adapt to multiple shapes.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a plastic mold processing clamping device, comprising a guide frame, a movable frame, and a clamping plate. Two movable frames are slidably mounted on the guide frame, and a clamping plate is fixedly connected to the movable frame. The device also includes a friction plate, a cylinder, a push frame, a push plate, an extrusion rod, a pressure plate, and an elastic element. A friction plate is fixedly connected to the clamping plate, and a cylinder is mounted on the clamping plate. A push frame is mounted on the telescopic rod of the cylinder, and a push plate is fixedly connected to the push frame. Extrusion rods are slidably mounted on the push plate at even intervals, and a pressure plate is fixedly connected to the extrusion rods. An elastic element is sleeved on the extrusion rods, and both ends of the elastic element are connected to the extrusion rods and the push plate, respectively.

[0007] As a further preferred option, it also includes a connecting pipe and a suction frame. Four suction frames are provided on the clamping plate, and a connecting pipe is connected between the four suction frames. The connecting pipe is connected to an external air pump.

[0008] As a further preferred option, a soft pad is also included, with the suction frame having a soft pad.

[0009] As a further preferred option, it also includes anti-collision components, with two anti-collision components fixedly connected to the clamping plate.

[0010] As a further preferred option, the clamping plate is circular.

[0011] As a further preferred option, the clamping plate is made of rubber.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By starting the cylinder, the telescopic rod of the cylinder drives the push frame and the push plate to move inward, the push plate drives multiple extrusion rods to move inward, and the extrusion rods push the pressing plate to contact the mold surface under the action of the elastic element, so as to achieve multi-point uniform pressure and adapt to molds of different shapes.

[0013] 2. Connect to an external air pump via a connecting pipe. The external air pump generates negative pressure through the connecting pipe to adsorb onto the mold surface, enhancing clamping stability. Attached Figure Description

[0018] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0019] Example 1: A clamping device for processing plastic molds, see reference Figure 1 and Figure 2As shown, the device includes a guide frame 1, a movable frame 2, and a clamping plate 3. The movable frame 2 is slidably mounted on both the left and right sides of the guide frame 1. The clamping plate 3 is welded to the front of the movable frame 2. The device also includes a friction plate 4, a cylinder 5, a push frame 6, a push plate 7, a pressing rod 8, a pressure plate 9, and an elastic element 10. The friction plate 4 is fixedly connected to the inner side of the clamping plate 3. The cylinder 5 is bolted to the outer side of the clamping plate 3. The push frame 6 is mounted on the telescopic rod of the cylinder 5. The push plate 7 is fixedly connected to the push frame 6. The pressing rods 8 are evenly spaced and slidably mounted on the push plate 7. The pressing rods 8 are arranged in a 3×5 pattern. The pressing rods 8 pass through the friction plate 4 and the clamping plate 3. The pressure plate 9 is fixedly connected to the end of the pressing rod 8. The elastic element 10 is sleeved on the pressing rod 8. The two ends of the elastic element 10 are connected to the pressing rod 8 and the push plate 7, respectively.

[0020] See Figure 1 As shown, it also includes anti-collision components 14, which are symmetrically fixedly connected to the front side of the clamping plate 3.

[0021] See Figure 1 and Figure 2 As shown, the clamping plate 9 is circular.

[0022] See Figure 1 and Figure 2 As shown, the clamping plate 9 is made of rubber.

[0023] When this device is needed, the guide frame 1 is installed on the corresponding equipment, and the movable frame 2 is connected to the drive equipment, so that the drive equipment drives the movable frame 2 to move. The movable frame 2 drives the clamping plate 3 to move horizontally, realizing the clamping and release of the mold. The friction plate 4 on the inner side of the clamping plate 3 increases the clamping friction. When the two pressure plates 9 initially clamp the mold, the cylinder 5 is activated. The telescopic rod of the cylinder 5 drives the push frame 6 and the push plate 7 to move inward. The push plate 7 drives multiple extrusion rods 8 to move inward. Under the action of the elastic element 10, the extrusion rods 8 push the pressure plate 9 to contact the mold surface, realizing multi-point uniform pressure, adapting to molds of different shapes. The anti-collision element 14 first contacts the edge of the mold during the clamping process to absorb the collision energy.

[0024] Example 2: Based on Example 1, refer to Figure 3 As shown, it also includes a connecting pipe 11 and a suction frame 12. Four suction frames 12 are provided on the clamping plate 3. The four suction frames 12 are connected by a connecting pipe 11. The connecting pipe 11 passes through the clamping frame and is connected to an external air pump.

[0025] See Figure 3 As shown, it also includes a soft pad 13. The soft pad 13 is provided on the suction frame 12, and the contact surface of the soft pad 13 is on the same horizontal plane as the clamping surface of the clamping plate 3.

[0026] While clamping, the external air pump is connected through the connecting pipe 11. The external air pump generates negative pressure through the connecting pipe 11 to adsorb the mold surface, which enhances the clamping stability. The soft pad 13 provides flexible contact during adsorption to avoid scratching the mold surface.

[0027] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
