[0036] The supplementary description of the present invention is as follows: This design provides a simple, efficient, versatile and stable machining device, which not only solves the problems of complex operation, low efficiency and easy damage to molds in the existing technology, but also improves production efficiency and the applicability of the equipment through automation and adjustable design.

[0037] Example 1: A mold processing device for lateral demoulding, the mold processing device for lateral demoulding includes a fixed frame 1, an electric telescopic rod 9, a first U-shaped frame 11, a second U-shaped frame 12, a gear plate 15, a driving gear 19 and a driving motor 20; two symmetrically arranged electric telescopic rods 9 are installed at the bottom of the fixed frame 1, and the bottoms of the two electric telescopic rods 9 are connected to the top of the push plate 10, a first U-shaped frame 11 is installed at the bottom center of the fixed frame 1, and the second U-shaped frame 12 is installed on the left and right sides of the bottom of the fixed frame 1, respectively. Fixed gears 14 are installed at the front and rear ends of the first U-shaped frame 11, and the two fixed gears 14 are connected by a driving shaft 17. One end of the driving shaft 17 passes through the first U-shaped frame 11 and is rotatably connected to the first U-shaped frame 11. The outer periphery of the driving shaft 17 is located in the first U-shaped frame 11 and is sleeved with a driven gear ring 18. The driven gear ring 18 is meshed with the driving gear 19. The inner wall side of the first U-shaped frame 11 is equipped with a driving motor 20. The output end of the drive motor 20 is connected to the inner ring of the drive gear 19; the top and bottom of each fixed gear 14 are meshed with a tooth plate 15, and the two tooth plates 15 on the same side are connected by a movable frame 29, and two groups of limit grooves 16 are provided on the inner wall of each second U-shaped frame 12, and the side circumference of each group of tooth plates 15 passes through the corresponding limit groove 16 and is slidably connected to the limit groove 16.

[0038] During application: close the mold 28, then pour the molten steel from the liquid inlet and let it cool. After cooling, demoulding is carried out and the driving motor 20 is started so that the driving motor 20 drives the driving gear 19 to rotate, thereby driving the driven gear ring 18 to rotate as well, and then drives the driving shaft 17 to rotate as well, so that the two fixed gears 14 will rotate, thereby causing the two sets of tooth plates 15 to move. A second U-shaped frame 12 is provided, and the limiting groove 16 is used for limiting to ensure the stability of the movement of the tooth plates 15, so that the mold will slowly open to both sides, and two clamping plates 27 are provided so that the blank in the middle will not fall. Then start the electric telescopic rod 9 to make the push plate 10 slowly move and contact the blank. As the push plate 10 continues to move, the blank slowly moves away from between the two clamping plates 27, thereby completing the demoulding work.

[0039] Example 2: Example 2 is basically the same as Example 1, except that: Two fixing frames 13 are provided below the first U-shaped frame 11, and a first dovetail groove 24 is opened on the inner side of each fixing frame 13, and a first dovetail block 25 is slidably connected in each first dovetail groove 24, and the two first dovetail blocks 25 are connected by a third U-shaped frame 26; a plurality of connecting rods 23 are installed on the inner top of the third U-shaped frame 26, and the tops of all connecting rods 23 are connected to the bottom of the first U-shaped frame 11, and a splint 27 is fixedly installed on the side wall of each connecting rod 23; a threaded groove 21 is provided on the side wall of each fixing frame 13, and a threaded rod 22 is threadedly engaged between the two threaded grooves 21, and the threads at the left and right ends of the threaded rod 22 are set in opposite directions.

[0040] During application: for molds 28 of different sizes, in order to ensure that the entire device can work and demould stably, the distance between the two fixing frames 13 is adjusted according to the size of the mold 28. The adjustment process is to rotate the threaded rod 22. The threads at both ends of the threaded rod 22 have opposite directions. In this way, when the threaded rod 22 is rotated, the two fixing frames 13 approach or separate from each other, thereby making the overall application range of the device wider.

[0041] Example 3: Example 3 is basically the same as Example 1, except that: The top and bottom of each fixed plate 30 are fitted with a clamping frame 31, and each clamping frame 31 is fixedly connected to a plug plate 31. The top of the plug plate 31 is provided with a plug plate 39, and the side of the fixed plate 30 is provided with a slot 40. Each plug plate 39 is inserted into the corresponding slot 40 and slides with the slot 40; a plurality of first threaded holes 41 are provided on the side wall of each plug plate 39, and two third adjustment rods 38 are screwed on each fixed plate 30, and each third adjustment rod 38 extends into the corresponding first threaded hole 41 and is threadedly connected to the first threaded hole 41.

[0042] During application: the insert plate 39 can slide in the slot 40. When replacing a mold of a different model, the insert plate 39 is pulled out so that the third adjustment rod 38 can be aligned with the first threaded hole 41 at different positions for insertion and limiting. In this way, the device can be applied to a variety of molds of different models, making the device more widely applicable.

[0043] Example 4: Example 4 is substantially the same as Example 1, except that: The cam 33 is provided with a second screw hole 42 on the top of the first adjusting rod 32 and a second screw hole 42 on the bottom of the second adjusting rod 32. The cam 33 is provided with a second screw hole 42 on the top of the first adjusting rod 32 and a second screw hole 42 on the bottom of the second adjusting rod 32. The cam 33 is provided with a second screw hole 42 on the top of the first adjusting rod 32 and a second screw hole 42 on the bottom of the second adjusting rod 32. The cam 33 is provided with a second screw hole 42 on the top of the first adjusting rod 32 and a second screw hole 42 on the bottom of the second adjusting rod 32

[0044] During application: When locking the mold 28, first move the sliding plate 33 downward so that the fastening block 35 can be close to the top and bottom of the mold 28, so that the mold 28 is closed as a whole, and then rotate the first adjusting rod 32 to make the sliding plate 33 slide along the movable groove 37, so that the fastening block 35 can be fastened to the welding block 36, so as to ensure that the mold 28 can move with the movement of the two movable frames 29 during the demolding process, ensuring the normal progress of the mold closing and demolding work, and then rotate the second adjusting rod 34 into the second threaded hole 42 for further locking and limiting. In this way, the device can complete its work normally and ensure the stable clamping of the mold 28.

[0045] Example 5: Example 5 is basically the same as Example 1, except that: Brackets 2 are installed on the left and right sides of the top of the fixed frame 1, and an electromagnet 3 is installed on one end of the bracket 2 close to the fixed frame 1. A T-shaped rod 4 is inserted into the top of the fixed frame 1 corresponding to the electromagnet 3. The bottom of the T-shaped rod 4 passes through the fixed frame 1 and is connected to the top of the moving block 6; a spring 7 is sleeved on the outer surface of the T-shaped rod 4, and a stopper 8 is installed on the top side of the moving block 6. Limit blocks 5 are installed on the left and right sides of the bottom of the fixed frame 1, and the side of the limit block 5 on the same side is in contact with the side of the stopper 8. The bottom of the moving block 6 is arc-shaped, and the side of the moving block 6 is inclined.

[0046] When in use: after the clamping process, the two mobile frames 29 will gradually move closer and gradually come into contact with the curved side walls of the moving block 6, thereby prompting the moving block 6 to move upward, so that the inclined surface of the moving block 6 contacts the mobile frame 29, forming a secondary limit, reducing the load of the drive motor 20, thereby further ensuring the overall stability. At the same time, when the limit is released, the electromagnet 3 is started, so that the electromagnet 3 is energized to generate magnetic force, so that the T-bar 4 is adsorbed, so that the two mobile frames 29 can be smoothly loosened and demolded, ensuring the normal use of the device and the stability of the clamping.
