DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] Embodiment 1, as Figure 1 As shown, an adjustable U-shaped part non-indentation forming quick-change upper mold includes an upper mold bit 10 and an upper mold base 20.

[0024] The top of the upper die cutter head 10 is provided with a positioning groove 11, and the lower surface of the upper die base 20 is provided with a positioning strip 21;

[0025] Two groups of symmetrically distributed hooking members 30 are rotatably mounted on the upper die cutter head 10 , and a hooking groove 22 is provided on the upper die base 20 . The free ends of the hooking members 30 are hooked and fitted in the hooking groove 22 .

[0026] During installation, the positioning groove 11 of the upper die cutter head 10 and the positioning strip 21 on the upper die base 20 are aligned and aligned upward, and then the hook member 30 and the hook groove 22 are hooked and adapted to fix the upper die cutter head 10 and the upper die body 20. When disassembling, the upper die cutter head 10 and the upper die body 20 can be separated by deflecting the hook member 20 outward. It should be noted that when the hook member 30 and the upper die base 20 in this embodiment are in a hooked state, the angle between the hook member 30 and the top surface of the upper die cutter head 10 can be a right angle or an acute angle.

[0027] Embodiment 2, as Figure 2 and Figure 3 As shown, in the quick-change upper mold, the hook component 30 is an elastic telescopic structure, and the hook component 30 includes a fixed plate 31, a movable hook body 32 and a rotating body 33. The fixed plate 31 is fixedly installed on the side of the upper mold cutter head 10, and the rotating body 33 is rotatably installed on the fixed plate 31. A guide hole is provided on the side of the rotating body 33 away from the fixed plate 31, and a spring 34 and the movable hook body 32 are installed in the guide hole. A limiting ring 35 is provided at the end of the guide hole, and the limiting ring 35 is mounted on the movable hook body 32.

[0028] An operating plate 36 is installed on the side of the movable hook body 32 facing away from the upper die base 20 .

[0029] When installing the upper die cutter head 10 and the upper die base 20, the movable hook body 32 is extended upward relative to the rotating body 33 by operating the operating plate 36 and hooked in the hooking groove 22. When disassembling, the operating plate 36 is continued to be upward to extend it again until the hooking member 30 can be separated from the upper die base 20.

[0030] Embodiment 3, as Figure 4 and Figure 5 As shown, in the quick-change upper mold, the hook member 30 is provided with an elastic pin 40 obliquely pointing downward, and the upper mold base 20 is provided with an oblique hole 23 adapted to the elastic pin 40 .

[0031] The elastic pin 40 is installed at one end of the hook member 30 away from the upper die cutter head 10 , and the inclined hole 23 is disposed in the hook groove 22 .

[0032] The elastic latch 40 includes a stopper 41 and a pin 42. A T-shaped countersunk hole 43 is provided on the hook member 30. The side of the T-shaped countersunk hole 43 facing the upper mold base 20 is a large head portion, and a compression spring 45 is installed inside the T-shaped countersunk hole 43. The pin 42 passes through the T-shaped countersunk hole 43 and is located on the inner side of the compression spring 45. A stopper 41 is fixed to one end of the pin 42. The stopper 41 is located on the side of the hook member 30 facing away from the upper mold base 20. A stop ring 44 is fixed to the pin 42, and the stop ring 44 abuts against one end of the compression spring 45.

[0033] When the top of the hook member 30 approaches the hook groove 22, the pin 42 of the elastic plug can squeeze the compression spring 45, so that the pin 42 is hidden in the T-shaped countersunk hole 43. When the pin 42 enters the inclined hole, it will be clamped and adapted under the action of the compression spring 45. When replacing the upper die cutter head 10, it is only necessary to pull the block 41 outward to separate the pin 42 from the inclined hole, and then rotate the hook member 30 outward.

[0034] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution and inventive concept of the utility model should be included in the protection scope of the utility model.
