Therefore, they should not be construed as limitations on this utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0027] In one embodiment of this utility model, such as Figures 1-4 As shown, a fixing device for mold processing is provided, including a base 10, a lifting mechanism 20, a clamping plate mechanism, and a clamping rod mechanism 40. The base 10 has a central placement area for placing the workpiece. The lifting mechanism 20 is located on the placement area and has a lifting platform 21. The lifting mechanism 20 raises and lowers the lifting platform 21, driving it to be higher or lower than the top surface of the base 10. The clamping plate mechanism includes two symmetrically distributed clamping plate assemblies 30, located on both sides of the placement area, for fixing both sides of the workpiece. The clamping rod mechanism 40 is located between the two sets of clamping plate assemblies 30 for fixing the other two sides of the workpiece.

[0028] By setting up a clamping plate mechanism and a clamping rod mechanism 40, the clamping plate mechanism fixes both sides of the workpiece, and the clamping rod mechanism 40 fixes the other two sides of the workpiece. This design achieves all-round fixation of the four sides of the workpiece. Compared with the traditional method of fixing only two sides, it can better resist external forces, effectively prevent the mold from deviating in position, ensure the stability of the workpiece during the processing, and provide a reliable guarantee for subsequent processing work.

[0029] Preferably, it also includes a clamping mechanism for fixing the top of the workpiece. The clamping mechanism includes four sets of clamping components 50, with two pairs of clamping components 50 symmetrically distributed on the clamping plate assembly 30.

[0030] By setting up a clamping mechanism, under the action of the clamping plate mechanism and the clamping rod mechanism 40, pressure is applied to the workpiece from the top, forming a combined force with the surrounding fixation, constraining the workpiece from multiple dimensions, greatly enhancing the overall stability of the workpiece during the processing, effectively preventing the workpiece from moving or deforming, and ensuring the smooth progress of processing.

[0031] Furthermore, the clamping assembly 50 includes a support column 51, a connecting rod 52, and a clamping component mounted on the clamping plate assembly 30. The connecting rod 52 is rotatably mounted on the top of the support column 51, and a locking nut 55 is provided between the connecting rod 52 and the support column 51. The clamping component is located at the end of the connecting rod 52 away from the support column 51. By setting the support column 51 and the connecting rod 52, and using them in conjunction with the locking nut 55, the corresponding clamping component can be replaced according to different specifications and shapes of processed parts, improving the versatility and adaptability of the device, meeting the needs of various mold processing, avoiding processing instability due to inability to adapt to different processed parts, thereby reducing product scrap and lowering production costs.

[0032] In addition, when some processed parts cannot be clamped at the top, the locking nut 55 can be loosened, the connecting rod 52 and the clamping component can be rotated to the other side of the clamping plate 31 in the clamping plate assembly 30 and fixed by the locking nut 55, which can avoid interference from the clamping component, further improve the versatility and adaptability of the device, and meet the needs of various mold processing.

[0033] Furthermore, the clamping component includes a fixing screw 53 and a pressure plate 54. The fixing screw 53 is threadedly connected to one end of the connecting rod 52. The top end of the fixing screw 53 is provided with a limiting part 531, and the other end is connected to the pressure plate 54. The pressure plate 54 is provided with a first rubber layer 541 for protection. By setting the fixing screw 53 and the pressure plate 54, and by threading the fixing screw 53 to the connecting rod 52, the distance between the pressure plate 54 and the workpiece can be adjusted, thereby controlling the magnitude of the clamping force and better adapting to the clamping requirements of workpieces of different thicknesses. At the same time, by setting the first rubber layer 541, it can play a buffering and protective role during the clamping process, avoiding direct rigid contact between the pressure plate 54 and the workpiece, reducing damage to the surface of the workpiece, ensuring the appearance quality and dimensional accuracy of the workpiece, reducing the risk of product scrap due to surface damage, improving the product qualification rate, and reducing production costs.

[0034] Preferably, the clamping plate assembly 30 includes a clamping plate 31 and two sets of clamping plate driving members 32. The clamping plate 31 is slidably disposed on the base 10, and a first sliding groove (not shown in the figure) is provided between the clamping plate 31 and the base 10. The two sets of clamping plate driving members 32 are symmetrically distributed on the base 10, and both ends of the clamping plate 31 are respectively connected to the output ends of the two sets of clamping plate driving members 32. The clamping plate driving members 32 are cylinders, and the clamping plate driving members 32 are connected to an external negative pressure device. Conventional negative pressure control technology is used between the cylinders and the external negative pressure device, which will not be described in detail here. A second rubber layer for protection is provided on the side of the clamping plate 31 near the workpiece. The two sets of clamping plate driving members 32 are synchronously arranged, and the two sets of clamping plate driving members 32 synchronously drive the clamping plate 31 to move left or right along the first sliding groove on the base 10.

[0035] Two sets of clamping plate drive components 32 synchronously drive the clamping plates 31 to move along the first slide groove, ensuring uniform force on both sides of the workpiece and achieving stable fixation of both sides of the workpiece. The synchronous drive also prevents mold position displacement caused by uneven force, ensuring processing accuracy. Simultaneously, a second rubber layer is provided, which acts as a buffer and protector, reducing friction and collision between the clamping plates 31 and the workpiece, preventing surface damage to the workpiece, ensuring the appearance and dimensional quality of the workpiece, reducing the possibility of product scrap due to surface damage, improving product qualification rate, and reducing production costs.

[0036] Furthermore, the clamping plate 31 has a mounting cavity on the side away from the workpiece. The clamping rod assembly includes two sets of bidirectional telescopic cylinders 41 and two sets of clamping rods 42. Each set of bidirectional telescopic cylinders 41 is located in the mounting cavity and is connected to an external negative pressure device. The connection between the bidirectional telescopic cylinders 41 and the external negative pressure device uses conventional negative pressure control technology, which will not be described in detail here. The clamping rods 42 are located between the two sets of bidirectional telescopic cylinders 41, and both ends of the clamping rods 42 extend into the mounting cavity and are connected to the same output end of the two sets of bidirectional telescopic cylinders 41 via connecting blocks 43. The two sets of bidirectional telescopic cylinders 41 are set synchronously. The synchronous setting of the two sets of bidirectional telescopic cylinders 41 ensures that the clamping rods 42 synchronously fix the other two sides of the workpiece, making the workpiece subject to uniform force and effectively preventing positional deviation caused by uneven force on both sides.

[0037] Furthermore, sliders 44 are provided between the upper and lower ends of the connecting block 43 and the mounting cavity. By setting sliders 44, the friction of the connecting block 43 during movement can be reduced, making the clamping rod 42 move more smoothly and stably under the drive of the bidirectional telescopic cylinder 41. This ensures the stability of the processed parts during processing, reduces the probability of product deformation and scrap due to unstable fixing, and lowers production costs.

[0038] Preferably, the base 10 has a recessed fixed cavity at the center of its top surface. The lifting mechanism 20 includes a lifting drive component 22 and a guide plate 23 disposed within the fixed cavity. The top of the lifting drive component 22 is connected to the lifting plate. The lifting drive component 22 is a motor-driven displacement mechanism, generally using a conventional electric telescopic push rod or electric telescopic column structure, which will not be elaborated here. The guide plate 23 is disposed on the output end of the lifting drive component 22, and a guide post 24 is provided between the guide plate 23 and the fixed cavity. The guide plate 23 is slidably connected to the guide post 24. By setting the lifting drive component 22, the lifting drive component 22 can control the lifting platform 21 to move up or down, so as to facilitate the height adjustment of the workpiece. At the same time, the cooperative design of the guide plate 23 and the guide post 24 can provide precise guidance for the lifting of the lifting platform 21, ensuring a smooth and accurate lifting process and avoiding shaking or deviation during the lifting process.

[0039] Furthermore, the top surface of the lifting platform 21 is provided with a third rubber layer for protection (not shown in the figure). By providing the third rubber layer, it can play a buffering and protective role during the placement and processing of the workpiece.

[0040] Preferably, the bottom surface of the base 10 is provided with an anti-slip pad (not shown in the figure). The anti-slip pad is a conventional anti-slip structure, which will not be described in detail here. The anti-slip pad increases the friction between the device and the worktable, preventing the device from moving due to external forces or vibrations during processing.

[0041] In this embodiment, the base 10 is also equipped with a controller, which has multiple sets of control buttons. These buttons correspond to different functions on the lifting mechanism 20, the clamping plate mechanism, and the clamping rod mechanism 40, such as raising and lowering the lifting mechanism 20, moving the clamping plate mechanism forward and backward, adjusting the clamping rod mechanism 40 left and right, and power switching. The controller is electrically connected to the lifting mechanism 20, the clamping plate mechanism, and the clamping rod mechanism 40. This electrical connection uses conventional electrical connection technology and will not be described in detail here. By setting up the controller, operators can easily operate and adjust each mechanism according to the actual production situation, simplifying the operator's steps and improving the practicality of the device.

[0042] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
