Detailed Implementation

[0018] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0019] like Figures 1-4 As shown, a deformation correction device for mold steel includes a base frame 1. An L-shaped plate 2 is rotatably connected to the top center of the base frame 1. Supports 3 are fixed to the left and right sides of the top of the base frame 1. An electric slide rail 4 is mounted on both supports 3. An electric push rod 5 is fixed to the output end of the electric slide rail 4. A pressure plate 6 is fixed to the telescopic rod of the electric push rod 5. When mold steel is placed in the two panels of the L-shaped plate 2, the rotation of the L-shaped plate 2 can cause the mold steel to flip to correct other surfaces. The electric slide rail 4 drives the electric push rod 5 and the pressure plate 6 to move so that the pressure plate 6 can be kept aligned with the upper surface of the flipped mold steel.

[0020] A positioning groove 101 is opened in the middle of the top of the base frame 1. The L-shaped plate 2 is rotatably connected to the middle of the positioning groove 101. A motor 11 is installed on the outer side of the positioning groove 101. The output shaft of the motor 11 is connected to the rotation shaft of the L-shaped plate 2. The L-shaped plate 2 is driven to flip in the positioning groove 101 by the forward and reverse rotation of the output shaft of the motor 11.

[0021] The two sides of the top of the base frame 1 are slidably provided with limiting plates 7, which are matched with the two panels of the L-shaped plate 2 respectively to clamp and limit the die steel.

[0022] A guide rod 12 is connected between the limiting plate 7 and the bracket 3 on the same side of the limiting plate 7, one end of the guide rod 12 is fixedly connected with the limiting plate 7, the other end of the guide rod 12 is slidably connected with the bracket 3, an elastic member 13 is sleeved on the guide rod 12, and the two ends of the elastic member 13 are connected with the limiting plate 7 and the bracket 3 respectively to provide a reset force for the limiting plate 7.

[0023] The top of the limiting plate 7 is provided with an inclined surface 701, and the distance between the two limiting plates 7 is less than the length of the positioning groove 101, so that when the L-shaped plate 2 is turned over, one panel of the L-shaped plate 2 can push the limiting plate 7 to slide along the guide rod 12.

[0024] An electric push rod 8 is mounted on one side of the top of the base frame 1, a pressing plate 9 is fixedly connected on the telescopic rod of the electric push rod 8, and a limiting plate 10 is fixedly connected on the top of the base frame 1 opposite to the pressing plate 9, so that the front and rear sides of the die steel can be corrected through the cooperation of the pressing plate 9 and the limiting plate 10.

[0025] The limiting plate 10 and the top of the base frame 1 are provided with a reinforcing rib 14 to enhance the strength and stability of the structure.

[0026] The side of the two limiting plates 7 close to each other and the side of the limiting plate 10 close to the pressing plate 9 are provided with anti-skid layers (not shown in the figure) to prevent the die steel from sliding or shifting during the correction process.

[0027] The working principle of the embodiment is as follows: initially, one panel of the L-shaped plate 2 is located on the right side in the positioning groove 101, in use, first, the mold steel to be corrected is placed between the two panels of the L-shaped plate 2, the right limiting plate 7 is in contact with the mold steel under the elastic action of the corresponding elastic member 13, so that the mold steel is kept stable on the L-shaped plate 2, then the pressing plate 6 is driven downward by the electric push rod 5 to extrude and correct the mold steel, the chassis 1 provides support for the L-shaped plate 2 and the mold steel thereon, then the pressing plate 6 is driven upward by the electric push rod 5 to reset, then the L-shaped plate 2 is turned by 90 degrees by the motor 11, so that the L-shaped plate 2 drives the mold steel to be turned to between the pressing plate 2 and the limiting plate 2, in the process, one panel of the L-shaped plate 2 exerts pressure on the inclined surface 701 of the left limiting plate 1, so that the left limiting plate 1 moves left, after the L-shaped plate 2 is turned, the left limiting plate 1 moves right under the elastic action of the corresponding elastic member 13 to limit the mold steel, then the above operation is repeated, the pressing plate 6 is driven downward by the electric push rod 5 to extrude and correct the mold steel, and the pressing plate 6 is reset after the correction is completed, finally, the pressing plate 9 is driven by the electric push rod 2 to move and extrude the mold steel to correct the front and rear sides of the mold steel, the limiting plate 10 provides support for the mold steel, in this way, the six surfaces of the mold steel can be corrected in all directions.

[0028] The above only describes the preferred embodiments of the utility model and is not used to limit the utility model, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
