[0019] like Figure 1 As shown, an embodiment of this application provides an automatic tooling locking and anti-fall mechanism, including a base 1. The base 1 is provided with a locking mechanism 2 for locking the tooling and an anti-fall mechanism 3 for fixing the locking mechanism 2. The locking mechanism 2 includes a mounting base 21, a first driving mechanism 22 and a locking template 23. The mounting base 21 is mounted on the base 1. The first driving mechanism 22 is rotatably connected to the mounting base 21 via a rotating shaft 24. The driving end of the first driving mechanism 22 is hinged to one end of the locking template 23. The middle part of the locking template 23 is rotatably connected to the mounting base 21 via a connecting shaft 25. The mounting base 21 and the base 1 are respectively provided with a first through hole 26 for the locking template 23 to pass through. The rotating shaft 24 and the connecting shaft 25 are not on the same horizontal plane and the rotating shaft 24 is located obliquely above the connecting shaft 25.

[0020] The fall arrestor 3 includes a second drive mechanism 31 and a positioning post 32. The second drive mechanism 31 is installed at one end of the mounting base 21, and the drive end of the second drive mechanism 31 is connected to the positioning post 32. The locking template 23 is provided with a positioning hole 231 for positioning and cooperating with the positioning post 32. The second drive mechanism 31 drives the positioning post 32 to pass through the mounting base 21 and extend into the positioning hole 231 of the locking template 23 to position the locking template 23.

[0021] Specifically, when the fixture for fixing the mold is placed at the bottom of the base 1, the first drive mechanism 22 of the locking mechanism 2 drives the second connecting part 234 of the locking template 23 to move forward, the first connecting part 233 of the locking template 23 rotates clockwise around the connecting shaft 25, and the locking part 232 of the locking template 23 rotates clockwise to lock the fixture at the bottom of the base 1. Then, the second drive mechanism 31 of the anti-fall mechanism 3 drives the positioning pin 32 to extend into the second through hole 271 of the fixing block 27, the positioning hole 231 of the locking template 23 and the second through hole 271 of another fixing block 27 to fix the locking plate. When it is necessary to loosen the tooling and mold for replacement, the first drive mechanism 22 of the locking mechanism 2 drives the second connecting part 234 of the locking template 23 to move backward, the first connecting part 233 of the locking template 23 rotates counterclockwise around the connecting shaft 25, the locking part 232 of the locking template 23 rotates counterclockwise to loosen the tooling, and the first drive mechanism 22 pulls the locking template 23 to move backward and rotates around the rotating shaft 24 under force.

[0022] The locking mechanism 2 and the anti-falling mechanism 3 are arranged to cooperate with each other, so that the locking of the tool is realized, and the falling of the tool and the mold is prevented, and the safety of the equipment is improved. The first driving mechanism 22 is rotatably arranged on the mounting seat 21, so that when the locking plate 23 is pulled to loosen the tool, the locking plate 23 can be slightly adjusted and swung under force, and the locking and loosening efficiency of the locking plate 23 is improved. The locking anti-falling mechanism 3 has a simple structure, is convenient to operate, can effectively prevent the tool and the mold from falling, and improves the safety.

When the locking plate 23 locks the tool, the second driving mechanism 31 drives the positioning columns 32 to sequentially extend into the second through hole 271 of the first fixed block 27, the positioning hole 231 of the locking plate 23 and the second through hole 271 of the second fixed block 27. The arrangement of the fixed block 27 improves the fixing strength of the positioning column 32 to the locking plate 23, and when the first driving mechanism 22 fails, the rotating of the locking plate 23 is effectively prevented, the falling of the mold and the tool is effectively avoided, and the safety of the equipment is improved.

[0024] As shown in Figure 3 one of the embodiments, the locking plate of the tool automatic locking anti-falling mechanism comprises a locking portion 232 for locking the tool, a first connecting portion 233 for rotatably connecting with the mounting seat 21 and a second connecting portion 234 for rotatably connecting with the driving end of the first driving mechanism 22, and the first connecting portion 233 is located between the locking portion 232 and the second connecting portion 234. The first driving mechanism 22 drives the second connecting portion 234 to move forward, the second connecting portion 234 drives the first connecting portion 233 and the locking portion 232 to rotate clockwise around the connecting shaft 25, so that the locking portion 232 locks the tool. The first driving mechanism 22 drives the second connecting portion 234 to move backward, the second connecting portion 234 drives the first connecting portion 233 and the locking portion 232 to rotate counterclockwise around the connecting shaft 25, so that the locking portion 232 loosens the tool. The arrangement of the locking plate 23 facilitates the locking and loosening operation of the tool in cooperation with the first driving mechanism 22.

When the first cylinder 222 drives the die plate 23 to move backward, the first cylinder 222 is forced to drive the rotating shaft 24 to rotate around the mounting base 21 for fine adjustment. The first cylinder 222 drives the die plate 23 to lock and release the tooling. The arrangement improves the locking and releasing efficiency of the die plate 23.

[0026] As Figure 2 As shown in the drawings, in one of the embodiments, the second driving mechanism 31 of the automatic die locking and falling prevention mechanism of the tooling comprises a connecting base 311 and a second cylinder 312, the connecting base 311 is installed on the mounting base 21, and the second cylinder 312 is installed on the connecting base 311.
