[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] like Figure 1-3As shown, the utility model provides a technical solution: a hydraulic bending machine mold replacement device, comprising a hydraulic bending machine body 1, a mold body 2 is placed below the bending blade of the hydraulic bending machine body 1, and the front and rear side surfaces of the hydraulic bending machine body 1 below the mold body 2 are rotatably penetrated by a rotating shaft 5, and the outer surface of the rotating shaft 5 is fixedly connected to a fixing plate 6, one end of the fixing plate 6 is fixedly connected to a clamping block 7, and the clamping block 7 is engaged with the mold body 2. The clamping connection between the clamping block 7 and the mold body 2 facilitates the mold body 2 to be quickly installed and fixed on the hydraulic bending machine body 1, and when the clamping block 7 is disconnected from the mold body 2, it is also convenient to quickly detach the mold body 2 from the hydraulic bending machine body 1, and one side of the rotating shaft 5 passes through the end A gear 9 is fixedly connected, and a motor 10 is fixedly connected to the outer surface of the hydraulic bending machine body 1, and the output shaft of the motor 10 is fixedly connected to one of the gears 9. A transmission gear set 11 is rotatably connected to the surface of one side of the hydraulic bending machine body 1, and the transmission gear sets 11 are meshed with each other and meshed with the gear 9 at the same time. With the help of the connection of the transmission gear set 11, when the motor 10 is driven, the gears 9 on both sides and the rotating shaft 5 will be driven to rotate in the opposite direction, so that the corresponding fixed plates 6 and the clamping blocks 7 on both sides move in the opposite direction, so that the clamping blocks 7 can be quickly connected to or disconnected from the mold body 2, instead of the staff to quickly disassemble or install the mold body 2 on the hydraulic bending machine body 1, so that the staff can quickly replace the mold.

[0020] Example 2

[0021] like Figure 1-3 As shown, the hydraulic bending machine body 1 is fixedly connected to a limiting plate 3 at a position near the mold body 2. With the help of the limiting plate 3, the correct installation position of the mold body 2 on the hydraulic bending machine body 1 is limited, so that the replaced mold body 2 can be quickly placed in the correct position. One end of the limiting plate 3 is fixedly connected to a blocking plate 4. With the help of the blocking plate 4, the replaced mold body 2 is prevented from excessively moving on the hydraulic bending machine body 1, so that the mold body 2 is in the correct position after stopping moving, and there is no need to repeatedly move and debug. Several fixed plates 6 and clamping blocks 7 are equidistantly arranged on the rotating shaft 5 along its extension direction, which effectively improves the stability of the mold body 2 installed and fixed on the hydraulic bending machine body 1. Rubber pads 8 are fixedly connected to the upper and lower surfaces of the clamping block 7. By filling the rubber pad 8, the tightness of the connection between the clamping block 7 and the mold body 2 is improved, and the stability of the mold body 2 on the hydraulic bending machine body 1 after being connected to the clamping block 7 is further improved.

[0022] Working principle:

[0023] like Figure 1-3As shown, when the utility model is in use, when the mold body 2 needs to be replaced after being used for a long time, the user first controls the motor 10 to start the rotation of the gear 9 on one side. With the help of the transmission gear set 11, when the gear 9 on one side rotates, it will simultaneously drive the reverse rotation of the gear 9 on the other side. The rotational movement of the two gears 9 drives the rotating shaft 5 and the fixed plate 6 on both sides of the hydraulic bending machine body 1 to rotate in the opposite direction, so that the clamping block 7 is disconnected from the mold body 2, so that the mold body 2 can be moved again, and then the old mold body 2 is manually moved and removed from the hydraulic bending machine body 1, and the new mold body 2 is moved along the limit plate 3 to the blocking plate 4 and then stopped, and then the clamping block 7 is reconnected to the mold body 2 to complete the replacement operation, which is simple and quick.
