In use, the casting mold is placed on the platform, and the vertical and horizontal moving components clamp and fix the casting mold without manual adjustment, enabling automatic opening and closing, improving work efficiency, and allowing clamping and fixing casting molds of different sizes, thus improving practicality. However, the above-mentioned prior art requires multiple motors to achieve the clamping effect when clamping casting molds of different sizes, resulting in a complex structure. Therefore, there is an urgent need for a casting mold opening and closing clamp. Utility Model Content

[0008] When clamping the casting mold, the casting mold is placed on the clamping platform, so that the casting mold is positioned between two vertical plates, and the back of the casting mold is in contact with the first clamping plate on the right side of the left vertical plate. The electric push rod pushes the right vertical plate, causing the right vertical plate to move to the left and contact the casting mold.

[0009] Preferably, the front of each of the two upright plates is provided with a rotating handwheel, the back of the lead screw is movably connected to the moving groove, and the front of the lead screw movably passes through the upright plate and is fixedly connected to the rotating handwheel.

[0010] Preferably, the bottom of the work box is fixedly connected to four support legs, which are respectively located at the four corners of the bottom of the work box.

[0011] Turn the handwheel to move the lead screw and the moving block, so that the back of the second clamping plate contacts the casting mold and clamps and fixes the casting mold.

[0012] Preferably, a motor is fixedly connected to the right side of the work box, a horizontal groove is provided in the bottom wall of the work box, a bidirectional threaded screw is provided in the horizontal groove, and the right side of the bidirectional threaded screw movably passes through the work box and is fixedly connected to the motor.

[0014] When the height of the clamping platform needs to be adjusted, the motor rotates the bidirectional threaded screw, causing the slider to move the first hinge seat inward, which in turn raises the clamping platform by the cross-bracing rods, thus facilitating height adjustment.

[0015] Preferably, the support rods are arranged in a cross pattern, and the top of the second hinge seat is fixedly connected to the clamping platform.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] Firstly, in this utility model, when clamping a casting mold, the casting mold is placed on a clamping platform, positioned between two vertical plates, with the back of the casting mold abutting against the first clamping plate on the right side of the left vertical plate. An electric push rod pushes the right vertical plate, causing it to move to the left and contact the casting mold. Then, rotating the handwheel causes the lead screw to move the moving block, bringing the back of the second clamping plate against the casting mold, thus clamping and fixing the casting mold. This provides a good clamping effect and allows for clamping casting molds of different sizes, saving costs.

[0018] Second, the utility model, when the height of the clamping table needs to be adjusted, the motor is set, and the motor rotates the bidirectional threaded screw, so that the slider drives the first hinge seat to move inward at the same time, so that the cross support rods raise the clamping table, thereby facilitating the height adjustment and meeting the needs of clamping processing of different heights and different heights.

[0030] The front of each of the two upright plates 22 is provided with a rotating handwheel 26, the back of the lead screw 24 is movably connected to the moving groove, and the front of the lead screw 24 movably passes through the upright plate 22 and is fixedly connected to the rotating handwheel 26.

[0031] The bottom of the work box 1 is fixedly connected with four support legs 11, which are respectively located at the four corners of the bottom of the work box 1.

[0032] With the above technical solution, when clamping the casting mold, the casting mold is placed on the clamping platform 2, so that the casting mold is positioned between two vertical plates 22, and the back of the casting mold is in contact with the first clamping plate on the right side of the left vertical plate 22. The electric push rod 21 pushes the right vertical plate 22, causing the right vertical plate 22 to move to the left and contact the casting mold. Then, the handwheel 26 is rotated, so that the lead screw 24 drives the moving block to move, so that the back of the second clamping plate contacts the casting mold, thus clamping and fixing the casting mold. The clamping effect is good, and casting molds of different sizes can be clamped, saving costs.

[0033] Example 2

[0034] Please see Figure 3 , Figure 4 Furthermore, based on Embodiment 1, the following is obtained: a motor 12 is fixedly connected to the right side of the work box 1, a horizontal groove is provided on the bottom wall of the work box 1, a bidirectional threaded screw 13 is provided in the horizontal groove, and the right side of the bidirectional threaded screw 13 movably passes through the work box 1 and is fixedly connected to the motor 12.

The top of the sliders is fixedly connected to the first hinge seat respectively. The first hinge seat is hinged to the inside of the first hinge seat respectively. The top of the support rod 14 is provided with the second hinge seat respectively.

[0036] The support rods 14 are arranged crosswise, and the tops of the second hinged seats are fixedly connected to the clamping platforms 2 respectively.

[0037] With the above technical solution, when it is necessary to adjust the height of the clamping table 2, the motor 12 is set up to rotate the bidirectional threaded screw 13, which causes the slider to move the first hinge seat inward at the same time, so that the cross support rod 14 raises the clamping table 2, thereby facilitating the height adjustment and meeting the clamping processing needs of different heights.

[0038] In actual operation, when this device is in use, the casting mold is placed on the clamping platform 2, positioned between the two vertical plates 22, with the back of the casting mold against the first clamping plate on the right side of the left vertical plate 22. The electric push rod 21 pushes the right vertical plate 22, causing it to move to the left and contact the casting mold. Then, the handwheel 26 is rotated, causing the lead screw 24 to move the moving block, so that the back of the second clamping plate contacts the casting mold, thus clamping and fixing the casting mold. The clamping effect is good, and it can clamp casting molds of different sizes, saving costs.

[0039] When the height of the clamping table 2 needs to be adjusted, the motor 12 is installed to rotate the bidirectional threaded screw 13, which causes the slider to move the first hinge seat inward at the same time, so that the cross support rod 14 raises the clamping table 2, thereby facilitating height adjustment and meeting the clamping and processing needs of different heights.
