[0037] Specifically, the mold fixing device is provided with an enclosing frame 10, a plurality of driving rods 20 and a fastening frame 30. When performing the fixing work of the casting mold, the enclosing frame 10 is first enclosed in the casting mold, and each driving rod 20 is arranged at intervals and rotatably connected to the enclosing frame 10. The fastening frame 30 is located on the inner side of the enclosing frame 10 and is threadedly connected to each driving rod 20, so that during the rotation of each driving rod 20, the fastening frame 30 can be driven to move, and the fastening frame 30 is pressed against the casting mold in the direction of the casting mold, thereby achieving the fixing of the casting mold. Since the mold fixing device is also provided with a transmission module 40, the transmission module 40 is connected to each driving rod 20. During the fixing and disassembly process of the casting mold, it is only necessary to control the rotation of the transmission module 40 to make each driving rod 20 rotate synchronously and drive the fastening frame 30 to move, and there is no need to separately control each driving rod 20, which provides convenience for the fixing and disassembly of the casting mold.

[0038] It can be understood that the enclosing frame 10 can be an integrated frame structure, or a frame structure formed by detachably connecting and enclosing two or more frames.

[0039] In one embodiment, Figure 1-4As shown, the enclosing frame 10 includes a mold clamping frame 11 and a clamping plate 12, a disassembly opening 111 is provided on one side of the mold clamping frame 11, and the clamping plate 12 includes a hinged end 121 and a blocking end 122, the hinged end 121 is located at one side of the disassembly opening 111 and is hinged to the mold clamping frame 11, and the blocking end 122 can be connected to the mold clamping frame 11 and block the disassembly opening 111 by rotating the hinged end 121 around the hinged part. Specifically, when installing the enclosing frame 10, it is only necessary to rotate the clamping plate 12 to open the disassembly opening 111, and then install the mold clamping frame 11 on the casting mold through the disassembly opening 111, and then connect the blocking end 122 of the clamping plate 12 to the mold clamping frame 11 to block the disassembly opening 111, so as to complete the installation of the enclosing frame 10, thereby providing convenience for the installation of the enclosing frame 10.

[0040] It can be understood that the blocking end 122 can be fixed to the mold closing frame 11 by means of snap connection with the mold closing frame 11, friction between the blocking end 122 and the mold closing frame 11, or by providing any other locking member.

[0041] In this embodiment, Figure 1-4 As shown, the closing plate 12 is opposite to the fastening frame 30, and a first flexible pad 123 is provided on a side of the closing plate 12 close to the fastening frame 30, and a second flexible surface 31 is provided on a side of the fastening frame 30 close to the closing plate 12.

[0042] In one embodiment, Figure 1-4 As shown, the enclosure frame 10 further includes a locking rod 13, which is connected to the mold clamping frame 11 and is used to lock the blocking end 122 by connecting to the blocking end 122. Specifically, after the blocking end 122 is connected to the mold clamping frame 11 by rotating the clamping plate 12, the locking rod 13 is connected to the blocking end 122 to limit the blocking end 122, thereby locking the blocking end 122. When the mold removal work is required, only the locking rod 13 needs to be taken out.

[0043] In this embodiment, the locking rod 13 is a bolt, and the bolt is threadedly connected to the mold clamping frame 11 and the blocking end 122 .

[0044] In one embodiment, Figure 3-4 As shown, the mold clamping frame 11 is provided with an engaging groove 14, which is located on the rotation path of the blocking end 122, and the blocking end 122 can be engaged with the engaging groove 14 by the rotation of the hinge end 121. Specifically, the blocking end 122 is engaged with the engaging groove 14, so that the mold clamping frame 11 and the clamping plate 12 are integrated, and a stable connection with the mold clamping frame 11 is achieved.

[0053] In one embodiment, Figure 1-4 As shown, the enclosure frame 10 is provided with a protection cavity 16, and each transmission wheel 42 is located in the protection cavity 16. Specifically, the protection cavity 16 can provide position limiting and protection for the transmission wheel 42, the transmission belt 41 and the control wheel 43, so that the transmission of each driving rod 20 is more stable.

[0054] In one embodiment, Figure 1 As shown, the mold fixing device further includes a level ruler 50, which is mounted on the enclosure frame 10. By observing the horizontal state of the level ruler 50, the vertical state of the casting mold can be monitored.

[0055] The specific working principle of the mold fixing device provided by the embodiment of the utility model is as follows: the U-shaped mold frame 11 is sleeved on the outer wall of the casting mold through the disassembly and assembly port 111, and then the closing plate 12 is rotated to plug the plug hole 1221 of the blocking end 122 with the plugging protrusion 141 of the fitting groove 14, and then the locking rod 13 is inserted into the mold frame 11 and the plugging protrusion 141 to lock the blocking end 122 to complete the mold closing of the enclosure frame 10, and then the control handle 431 is rotated to drive the control wheel 43 to rotate, and the control wheel 43 drives each transmission wheel 42 to rotate through the transmission belt 41 of the transmission belt 41, so that each driving rod 20 rotates synchronously, and then drives the fastening frame 30 to move closer to the mold, and the casting mold is fixed by the squeezing effect of the fastening frame 30 and the closing plate 12 on the casting mold;

[0056] When the mold fixing device needs to be disassembled, it is only necessary to control the operating handle 431 to move the fastening frame 30 away from the casting mold, and then remove the locking rod 13. The mold fixing device can facilitate the fixing and disassembly of the casting mold.
