[0002] The machine tool ram is generally processed into a blank by a casting process, and then the blank is finely processed. During the casting process, a special casting mold is required, such as a ram casting mold disclosed in patent CN218836050U. In this technical solution, a cementitious material is poured into the mold cavity through a pouring hole on the mold top plate, so that the insert is condensed inside the cementitious material, and a casting cavity is formed inside the mold to realize the external structure of the ram. The upper and lower molds are required for positioning when closing the mold and taking out the ram.

[0003] However, when the upper mold and the lower mold are assembled, the device cannot be adjusted for positioning by using a traditional clamping mechanism, and cannot ensure that the mold is located in a position that matches the upper mold during assembly, which causes deformation and errors in the processing process, reduces product quality, and leads to reduced productivity. Utility Model Content

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] See also Figure 1-3The utility model provides a technical solution: a clamping fixture for a machine tool slide mold, comprising a support plate 2, a support platform 4 that can slide forward and backward is arranged on the support plate 2, a accommodating box 9 that can slide left and right is arranged above the support plate 2 and on the left side of the support platform 4, and clamps 8 extending to the left and movable forward and backward for clamping the lower mold are arranged at both ends of the left side of the accommodating box 9, two clamping blocks 3 that can move forward and backward are respectively arranged on the two clamping plates 8, a mechanical arm 6 is rotatably arranged on the support platform 4, a clamping claw 7 for clamping the upper mold is arranged at one end of the mechanical arm 6, and the mechanical arm 6 is located above between the two clamping plates 8.

[0019] In this embodiment, the clamping fixture is used on one side of the roller conveyor belt 1 for casting a ram mold.

[0020] The support plate 2 is provided with a slide rail, which drives the support platform 4 to slide. By moving the support platform 4, the mold can be clamped, positioned, installed and disassembled in different positions.

[0021] The mechanical arm 6 is rotatably mounted on the support platform 4 and can adjust its position in the horizontal direction and the vertical direction.

[0022] The clamping jaws 7 are used to clamp and move the mold.

[0023] The clamping plates 8 are extended and retracted by sliding the accommodating box 9 left and right, and the clamping blocks 3 on the two groups of clamping plates 8 are adjusted to clamp inwards to ensure the stability of the mold during the movement.

[0024] Furthermore, a hydraulic cylinder 17 is fixedly connected to the front side of the support platform 4 , and an output end of the hydraulic cylinder 17 is fixedly connected to the rear side of the receiving box 9 .

[0025] In this embodiment, when the hydraulic cylinder 17 is working, the extension and retraction of its piston rod will directly drive the movement of the containing box 9 in the left and right directions, thereby driving the clamping plate 8 to extend and retract. When it is not necessary to position the mold, it will withdraw to the right. When positioning is required, it will extend to the left. The mold can also be adjusted by left and right movements to ensure that the mold is in the fitting position of the upper mold assembly.

[0026] Furthermore, one end of the inner cavity of the accommodating box 9 is fixedly connected to a second motor 10, the output shaft of the second motor 10 is fixedly connected to a first bidirectional threaded rod 11, both ends of the surface of the first bidirectional threaded rod 11 are threadedly connected to first threaded sleeves 12, and the surfaces of the two first threaded sleeves 12 are fixedly connected to connecting blocks 18, and each connecting block 18 is fixedly connected to each clamping plate 8.

[0027] In this embodiment, the other end of the first bidirectional threaded rod 11 is rotatably connected to the accommodating box 9 .

[0028] The second motor 10 is started to drive the first bidirectional threaded rod 11 to rotate, thereby driving the two first threaded sleeves 12 to move inward or outward, thereby driving the clamping plate 8 to clamp and loosen the mold inward or outward.

[0029] Furthermore, a third motor 16 is horizontally arranged in the clamping plate 8, and the output shaft of the third motor 16 is fixedly connected to the second bidirectional threaded rod 15, and the second bidirectional threaded rod 15 has second threaded sleeves 14 threadedly connected at both ends of the surface, and the clamping block 3 is fixedly connected to the second threaded sleeve 14.

[0030] In this embodiment, the other end of the second bidirectional threaded rod 15 is rotatably connected to the clamping plate 8 .

[0031] By starting the third motor 16, the second bidirectional threaded rod 15 is driven to rotate, thereby driving the two second threaded sleeves 14 to move inward or outward, so that the clamping block 3 can clamp or loosen the mold.

[0032] Furthermore, a first motor 5 is vertically arranged in the support platform 4 , and an output shaft of the first motor 5 is fixedly connected to a rotating disk 13 , and a bottom of the mechanical arm 6 is fixedly connected to a top of the rotating disk 13 .

[0033] In this embodiment, the output shaft of the first motor 5 is provided with a reducer to ensure a slow speed during the rotation process and achieve precise positioning. By starting the first motor 5 to drive the rotating disk 13 to rotate, the robotic arm 6 is driven to rotate, so that the robotic arm 6 drives the clamping jaw 7 to rotate and feed the material.

[0034] Furthermore, the surfaces of the clamping jaws 7 , the clamping plates 8 and the clamping block 3 are all fixedly connected with anti-slip pads.

[0035] In this embodiment, the anti-skid pad can be made of rubber, silicone or other materials with excellent anti-skid performance. These materials are usually soft, wear-resistant, anti-aging and other properties, which can ensure that they still maintain good anti-skid effects during long-term use.

[0036] Working principle and use process of the utility model: After the utility model is installed, the clamping device is first installed on one side of the roller conveyor belt 1. After the support platform 4 slides on the support plate 2 to a suitable position, the mechanical arm 6 adjusts the position driven by the first motor 5, and clamps the mold through the clamping claw 7. The hydraulic cylinder 17 drives the containing box 9 to slide to a suitable position, and the second motor 10 starts to drive the clamping plate 8 to clamp inward to preliminarily fix the mold. The third motor 16 works, and the mold is firmly clamped by fine-tuning the clamping block 3. After the clamping is completed, the entire tooling can be moved to the next process for processing or transportation.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
