[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1-5 As shown, the utility model is a mold frame processing auxiliary fixture, including a base 1 and a box body 2, and a multi-directional fixing mechanism 3 is provided on the box body 2; the multi-directional fixing mechanism 3 includes a hydraulic telescopic column 31 fixedly connected to the top wall of the box body 2, the hydraulic telescopic column 31 is electrically connected to an external power supply and is controlled by an external program. The hydraulic telescopic column 31 monitors the position, speed, pressure and other parameters of the telescopic rod in real time by integrating internal components. Through the feedback mechanism, precise control of the telescopic movement can be achieved, and precise control can ensure high clamping precision. The output end of the hydraulic telescopic column 31 is fixedly connected to a connecting bar 32, and two transmission arms 33 are rotatably connected to the connecting bar 32. The two transmission arms 33 are rotatably connected to a sliding plate 34, and the tops of the two sliding plates 34 are provided with a clamping assembly 35. By providing a multi-directional fixing mechanism 3, only one hydraulic telescopic rod 31 is used to control the clamping action on both sides, which reduces the cost of use. The simultaneous bidirectional movement and clamping can ensure the synchronous application of the clamping force on both sides, improve the uniformity of the force on both sides, and the clamping assembly 35 also reduces the use of two motors, further reducing the cost of use.

[0026] The left clamping assembly 35 includes a connecting slot 351, the inner bottom wall of which is provided with a sliding hole 352. A first motor 353 is fixedly connected to the inner wall of the connecting slot 351. The first motor 353 is electrically connected to an external power source and controlled by an external program. The first motor 353 is a stepper motor that can precisely control the rotation angle and speed, as well as the direction of rotation. It also locks the output shaft when not in motion to ensure clamping stability. A screw 354 is fixedly connected to the output end of the first motor 353. Two sliding clamps 355 are threadedly connected to the surface of the screw 354. The surface of the screw 354 has two sections of threaded teeth facing opposite directions, and all sliding clamps 355 are adapted to fit between adjacent threads.

[0027] The bottom of the base 1 is fixedly connected to a supporting leg 4, and both sides of the box body 2 are fixedly connected to a sliding sleeve 5. A lifting adjustment mechanism 6 is provided between the box body 2 and the base 1. By setting the lifting adjustment mechanism 6, compared with two cylinders, a single motor drive, combined with precise transmission, can more easily achieve lifting synchronization and reduce the cost of use.

[0028] The lifting and lowering mechanism 6 includes a transmission gear rod 61, two limiting rods 62, and a base 63. The transmission gear rod 61 is fixedly connected to the bottom of the box body 2. The two limiting rods 62 and the base 63 are both fixedly connected to the top of the base 1. A second motor 64 is fixedly connected to the inner wall of the base 63. The second motor 64 is electrically connected to an external power source and is controlled by an external program. The second motor 64 is a stepper motor that can accurately control the rotation angle and speed of the stepper motor, as well as the direction of rotation. It can also lock the output shaft when not in motion to ensure the stability of the adjusted height. A gear 65 is fixedly connected to the surface of the output shaft of the second motor 64.

[0029] The two sliding plates 34 are both slidably connected to the box body 2. The two clamping components 35 have the same structure and are distributed symmetrically on the top of the two sliding plates 34. The two sliding clamping bars 355 on the left and the two sliding clamping bars 355 on the right are slidably connected to the adjacent sliding holes 352 respectively.

[0030] The two limiting rods 62 are respectively slidably connected to the adjacent sliding sleeves 5 , and the transmission gear rod 61 is meshed with the gear 65 .

[0031] There are four support legs 4 , which are distributed in a rectangular array at the bottom edge of the base 1 . The design of multiple support legs 4 ensures the stability of the device.

[0032] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0033] The working principle of the present invention is as follows: First, the second motor 64 is activated, driving the gear 65 on the output shaft to rotate. Due to the meshing between the gear 65 and the transmission gear 61, the rotation of the gear 65 simultaneously drives the transmission gear 61, which in turn drives the housing 2. The housing 2 is raised and lowered linearly on the surfaces of the two limit rods 62 via the sliding sleeves 5 on both sides, thereby adjusting the housing 2 and all its components to the desired height. Next, the hydraulic telescopic column 31 is activated, driving the connecting bar 32 at the output end downward. This movement of the connecting bar 32 simultaneously drives the two sliding plates 34 via the two transmission arms 33, causing them to slide toward opposite sides of the housing 2. This sliding action causes all the sliding bars 355 on the left and right sides to move inward, thereby securing the housing 2. Finally, the two first motors 353 are activated, driving the screw rods 354 to rotate. When the screw rod 354 rotates, the two oppositely oriented screw teeth on the screw rod 354 drive the two sliding clamping bars 355. Driven by the screw rod 354, the two sliding clamping bars 355 move inwardly within the inner wall of the sliding hole 352 until they come into close contact with the workpiece, thereby achieving the effect of fixing the front and rear sides.
