Referring to fig. 2, for the utility model discloses a die-cut mould quick positioner of die-cutting machine, the die-cutting machine includes organism lower plate 1 and the organism upper plate 2 that parallels with organism lower plate 1, is connected with cylinder 21 on the top surface of organism upper plate 2, has placed die-cut mould on the top surface of organism lower plate 1. The punching die comprises a lower template 3 and a mounting block 31 fixed on the bottom surface of the lower template 3, and four guide posts 32 are arranged on the top surface of the lower template 3 in a rectangular array manner. Two mounting blocks 31 are arranged in parallel, and the mounting blocks 31 are positioned between the lower bottom plate 1 and the lower template 3 of the machine body.

Referring to fig. 2 and 3, the mold quick positioning device includes two L-shaped blocks 4 disposed on the top surface of the machine body bottom plate 1 and abutting against the mounting block 31 of the mold, and the two L-shaped blocks 4 are symmetrically disposed, and the L-shaped blocks 4 can be screwed on the machine body bottom plate 1. The top surface of the L-shaped block 4 is provided with a positioning block 5 for fixing the lower template 3, the side surface of the positioning block 5 opposite to the lower template 3 is provided with a yielding groove 51 for the clamping and embedding of the lower template 3, the side surface of the positioning block 5 opposite to the lower template 3 is provided with a limiting groove 52 for the clamping and embedding of the guide pillar 32, and the cross section of the limiting groove 52 is semicircular. During the die holding, directly push away the mould 4 positions of L type piece and make installation piece 31 just in time offset with L type piece 4, guide pillar 32 inlay card simultaneously to the spacing groove 52 of locating piece 5 in, can accomplish the quick installation location of lower bolster 3, save the time that the manual work progressively adjusted and aim the screw hole position. The positioning block 5 fixes the lower template 3 and the guide post 32 of the die, so that the lower template 3 is prevented from being taken up or moved when the upper template of the die moves up and down, the original action of fixing the lower template 3 by screws can be replaced, and the die change time is saved. An inward inclined guide surface 41 is arranged at the upper opening of the inner wall of each L-shaped block 4, and when the lower template 3 is pushed in, the guide surface 41 has a guiding function, so that the pushing time of the lower template 3 aligning with the gap between the two L-shaped blocks 4 is further reduced; on the other hand, collision damage between the lower template 3 and the L-shaped block 4 is reduced, and the service life of the L-shaped block 4 is prolonged.

Referring to fig. 4 and 6, a fixing assembly for fixing the positioning block 5 and the L-shaped block 4 is arranged on the positioning block 5, the fixing assembly includes a sliding block 6 arranged along the length direction of the positioning block 5, and a sliding groove 61 in clamping fit with the sliding block 6 is formed in the top surface of the L-shaped block 4. The bottom surface of the sliding block 6 is embedded with a spring steel ball 7, the spring steel ball 7 comprises a ball body and a spring connected with the ball body, and the inner wall of the sliding groove 61 is provided with a clamping groove 71 in clamping fit with the spring steel ball 7. When the positioning block 5 is installed, the sliding block 6 is inserted into the sliding groove 61, the spring steel ball 7 is clamped and embedded into the clamping groove 71, the positioning block 5 is further fixed, and the movement of the positioning block 5 along the length direction of the positioning block 5 is limited. When the lower positioning block 5 needs to be detached, the positioning block 5 is pulled outwards along the horizontal direction, the ball head of the spring steel ball 7 returns after being subjected to outwards extrusion force deviating from the clamping groove 71, the ball head compresses the spring to deform, the spring steel ball 7 slowly slides out of the clamping groove 71, the sliding block 6 is gradually separated from the sliding groove 61, and the lower positioning block 5 can be detached conveniently and quickly.

Referring to fig. 4 and 5, in order to further improve the connection stability between the positioning block 5 and the L-shaped block 4, a magnetic element 8 is embedded and bonded on the side surface of the sliding block 6, and an absorbing element 81 magnetically attracted to the magnetic element 8 is embedded and bonded on the inner side wall of the sliding groove 61. In this embodiment, the magnetic member 8 is a magnet, and the adsorbing member 81 is an iron sheet. After the slide block 6 is clamped into the slide groove 61, the slide block 6 is tightly attached to the inner wall of the slide groove 61 under the action of the attraction force between the magnetic attraction piece 8 and the attraction piece 81.

The implementation principle of the embodiment is as follows: during the die holding, directly push away the mould 4 positions of L type piece and make installation piece 31 just in time offset with L type piece 4, guide pillar 32 inlay card simultaneously to the spacing groove 52 of locating piece 5 in, can accomplish the quick installation location of lower bolster 3, save the time that the manual work progressively adjusted and aim the screw hole position.

The positioning block 5 fixes the lower template 3 and the guide post 32 of the die, so that the lower template 3 is prevented from being taken up or moved when the upper template of the die moves up and down, the original action of fixing the lower template 3 by screws can be replaced, and the die change time is saved.

When the positioning block 5 needs to be detached, the attractive force between the magnetic attraction piece 8 and the adsorption piece 81 is overcome, the positioning block 5 is pulled outwards along the horizontal direction, at the moment, the ball head of the spring steel ball 7 retracts after being subjected to the outwards extrusion force deviating from the clamping groove 71, the ball head compresses the spring to deform, the spring steel ball 7 slowly slides out of the clamping groove 71, the sliding block 6 is gradually separated from the sliding groove 61, and the positioning block 5 can be detached conveniently and quickly.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
