Referring to fig. 3, a guard plate 25 may be disposed above the driving shaft 31, the guard plate 25 is fixedly disposed on the second end 2 of the mold, and the guard plate 25 may protect the driving shaft 31 to prevent external impurities from falling onto the driving shaft 31 and affecting the rotation of the driving shaft 31.

Referring to fig. 3, a pressing plate 26 may be disposed above the supporting cylinder top block 21, the pressing plate 26 is fixedly disposed on the second end 2 of the mold, and the pressing plate 26 may limit the position of the supporting cylinder top block 21, so as to prevent the supporting cylinder top block 21 from falling off when the second end 2 of the mold is inverted and turned over.

Referring to fig. 3 to 4, the driving apparatus may further include: the driving shaft 32, the driving shaft 32 and the driving shaft 31 are in transmission connection through a gear assembly 33, and a handle 34 for driving the driving shaft 32 to rotate is arranged on the driving shaft 32. The operator manually drives the handle 34 to rotate the drive shaft 31, thereby moving the support cylinder head block 21. Specifically, the power for rotating the driving shaft 31 is provided by the handle 34, the driving force at the handle 34 is transmitted to the driving shaft 31 through the driving shaft 32 and the gear assembly 33, and the driving shaft 31 drives the support cylinder top block 21 to move.

Before the press and the die part are used, the driving shaft 32 is unlocked by the locking assembly 4, an operator manually rotates the handle 34 to enable the two supporting cylinder ejector blocks 21 to be far away from each other, when the two supporting cylinder ejector blocks 21 move to the avoiding position, the driving shaft 32 is locked by the locking assembly 4, and the press can perform normal production action. Because the avoiding hole 221 of the supporting cylinder top block 21 is opposite to the position of the supporting cylinder 11, when the first end 1 of the mold moves towards the second end 2 of the mold, the supporting cylinder 11 passes through the avoiding hole 221 and cannot be contacted with the supporting cylinder top block 21, and the press machine sliding block does not need redundant pressure to overcome the pressure of the supporting cylinder 11, thereby achieving the purpose of energy conservation. After production is finished, the driving shaft 32 is unlocked by the locking assembly 4 again, the handle 34 is manually rotated, the two supporting cylinder ejector blocks 21 are simultaneously moved towards the middle to be moved to the jacking position (for example, the driving shaft 32 can be moved to the limit position), the driving shaft 32 is locked by the locking assembly 4, and at the moment, the die head 10 reaches the storage state.

In the embodiment of the present invention shown in fig. 6, the driving device is an automatic driving device, and human intervention is not needed. Specifically, the driving device is a driving cylinder 35, and the support cylinder top block 21 is driven by the driving cylinder 35 to move so that the support cylinder top block 21 is in a pushing position or a retreating position. Specifically, when the mold is in a working state, the driving cylinder 35 ejects the supporting cylinder top block 21, the avoidance hole 221 of the supporting cylinder top block 21 is opposite to the supporting cylinder 11, the press slide moves downwards, the supporting cylinder 11 is not in contact with the second end 2 of the mold, the supporting cylinder 11 is not stressed, and the purpose of energy conservation is achieved. After the workpiece is finished, the driving cylinder 35 drives the supporting cylinder ejector block 21 to retract, the avoiding hole 221 of the supporting cylinder ejector block 21 is staggered with the supporting cylinder 11, the supporting cylinder 11 reaches a storage state, the press moves downwards and then quickly clamps the upper sliding block to open, and the die reaches the storage state.

The supporting cylinders 11, the supporting cylinder top blocks 21 and the driving cylinders 35 correspond to one another. That is, when the number of the support cylinders 11 is two, the number of the support cylinder top blocks 21 is also two, and each support cylinder top block 21 is driven to move by the corresponding drive cylinder 35. The driving cylinder 35 is used for driving the supporting cylinder jacking block 21 to move, the automation degree is high, and the personal safety of operators is guaranteed.

Referring to fig. 3 and 6, the die tip 10 may further include: and the detection element 5 is arranged on the second end head 2 of the mold, and the detection element 5 is at least used for detecting whether the supporting cylinder top block 21 is in an avoiding position. The detection element 5 can be fixed to the second end 2 of the mould by means of screws. The sensing element 5 may be a sensor for sensing the real-time position of the support cylinder head block 21. The number of the detecting elements 5 may be plural.

In the embodiment where the driving cylinder 35 drives the supporting cylinder top block 21 to move, the sensing element 5 transmits the sensed position signal to the controller, and the controller is adapted to control the driving cylinder 35 to rotate or stop according to the position signal and the working state of the press. For example, when the press machine is working, the relative distance between the first end 1 of the mold and the second end 2 of the mold needs to be changed, at this time, the supporting cylinder top block 21 needs to be adjusted to the avoiding position, the supporting cylinder 11 needs to be aligned with the avoiding hole 221 of the supporting cylinder top block 21, and when the detecting element 5 detects that the supporting cylinder top block 21 is not in the avoiding position, the controller rotates the driving cylinder 35 to drive the supporting cylinder top block 21 to move to the avoiding position; when the detection member 5 detects that the support cylinder top block 21 has been placed at the retreat position, the controller stops the rotation of the drive cylinder 35 to keep the support cylinder top block 21 at the retreat position.

Similarly, when the press does not work, the relative distance between the first end 1 of the mold and the second end 2 of the mold does not need to be changed, at this time, the supporting cylinder ejector block 21 needs to be adjusted to the abutting position, the supporting cylinder 11 needs to be staggered with the avoidance hole 221 of the supporting cylinder ejector block 21, and when the detection element 5 detects that the supporting cylinder ejector block 21 is in the avoidance position, the controller enables the driving cylinder 35 to rotate so as to drive the supporting cylinder ejector block 21 to move to the abutting position; when the detecting element 5 detects that the supporting cylinder top block 21 is not in the retracted position, which means that the supporting cylinder top block 21 is in the jacking position, the controller stops the driving cylinder 35 to keep the supporting cylinder top block 21 in the jacking position.

In some embodiments, the detection elements 5 may be disposed on both sides of each supporting cylinder top block 21, and the distance between two detection elements 5 is greater than the width of the supporting cylinder top block 21, when the supporting cylinder top block 21 moves to be detected by one of the detection elements 5, it indicates that the supporting cylinder top block 21 is in the tightening position; when the support cylinder top block 21 moves to a position where it can be detected by another detecting element 5, it indicates that the support cylinder top block 21 is in the avoidance position, so that the position adjustment of the support cylinder top block 21 can be made more accurate and more reliable.
