In order to achieve the above purpose, the utility model provides a following technical scheme: the quick-release die comprises an upper die base and a lower die base, wherein an upper base plate and a clamping plate are sequentially arranged below the upper die base, a back plate and a stripper plate are arranged below the clamping plate, equal-height sleeves and springs are arranged at the positions of the clamping plate and the back plate, the ends of the equal-height sleeves are abutted against the back plate, stripper plate hooks are arranged on the side surfaces of the upper base plate and the stripper plate, a groove is formed in the middle of each stripper plate hook, hooks are formed on two sides of the groove, the two hooks are respectively hooked on the top end of the clamping plate and the bottom end of the back plate, the distance between the two hooks is larger than the sum of the thicknesses of the clamping plate and the back plate.

The punching device further comprises a punching needle, the punching needle penetrates through the clamping plate to be connected to the upper base plate, and a fixing screw for fixing the punching needle is arranged on the clamping plate.

Further it is provided with a plurality of to take off the board couple, a plurality of evenly distributed is in each side department of splint.

Further, at least two opposite side surfaces of the clamping plate are provided with plate-releasing hooks, and the number of the supporting plate hooks on each side surface is not less than two.

Furthermore, each side surface of the clamping plate is at least provided with two plate-removing hooks.

Compared with the prior art, the beneficial effects of the utility model are that: through addding the stripper hook in the side, when the needle is dashed in needs change, move down to the lower extreme with the upper die base, even take off flitch conflict die holder department, then will take off the bolt of connecting on the stripper hook and take off, and will take off the stripper hook and take off in proper order, make the stripper hook break away from splint and backplate, make the upper die base shift up again this moment, take off flitch and backplate will stop in die holder department, with it put aside can, alright change directly at this moment and dash the needle, whole in-process staff need not anxious part and drops to injure by a crashing object, and direct operation in the side, it is more convenient to operate.

Detailed Description

The embodiment of the quick release mold of the present invention is further described with reference to fig. 1 to 3.

A quick-release die comprises an upper die holder 1 and a lower die holder 8, wherein an upper backing plate 2 and a clamping plate 3 are sequentially arranged below the upper die holder 1, a back plate 4 and a stripper plate 5 are arranged below the clamping plate 3, an equal-height sleeve 11 and a spring 10 are arranged at the clamping plate 3 and the back plate 4, the end part of the equal-height sleeve 11 is abutted against the back plate 4, the side surfaces of the upper backing plate 2 and the stripper plate 5 are provided with stripper plate hooks 15, the middle of the stripper plate hooks 15 is provided with a groove, hooks 151 are formed at two sides of the groove, the two hooks 151 are respectively hooked at the top end of the clamping plate 3 and the bottom end of the back plate 4, as shown in fig. 2, the upper mat 2 and the stripper plate 5 are shorter than the back plate 4 of the clamping plate 3 at the stripper hook 15, that is, the clamping plate 3 and the backing plate 4 are protruded from the upper mat 2 and the stripper plate 5 in a lateral direction, and the distance between the two hooks 151 is greater than the sum of the thicknesses of the clamping plate 3 and the backing plate 4, the plate-removing hook 15 is fixedly connected with the clamping plate 3 and/or the back plate 4 through a bolt 152.

As shown in fig. 2, in which the bolt 152 also penetrates the stripper hook 15 and the clamping plate 3 from the side.

Wherein, the lower die base 8 is provided with a lower backing plate 7 and a lower template 6 in sequence.

When the height-adjustable back plate is in work, the plate-removing hook 15 can prevent the distance between the clamping plate 3 and the back plate 4 from increasing, but does not influence the distance between the clamping plate 3 and the back plate 4 to be reduced, and at the moment, the end part of the equal-height sleeve 11 does not need to be fixed with the back plate 4, and the end part of the equal-height sleeve 11 preferably abuts against the back plate 4.

When the punch pin 13 needs to be replaced, firstly, the upper die base 1 is lowered, the stripper plate 5 is abutted against the lower die plate 6, then the bolt 152 arranged on the stripper plate hook 15 is taken down, the stripper plate hook 15 is taken down from the clamping plate 3 and the back plate 4, at the moment, the stripper plate 5 and the back plate 4 are directly separated from the clamping plate 3 and the upper backing plate 2, the upper die base 1 moves upwards, the stripper plate 5 is still abutted against the lower die plate 6, the upper die base 1 carries the upper backing plate 2 and the clamping plate 3 to reset, and at the moment, a worker can directly operate the punch pin 13 to replace the punch pin; after the punch pin 13 is replaced, the upper die holder 1 moves downwards, and the two hooks 151 of the plate-removing hook 15 are hooked at the top end of the clamping plate 3 and the bottom end of the back plate 4 respectively.

The present embodiment preferably further comprises a punch pin 13, the punch pin 13 passes through the clamping plate 3 to be connected to the upper backing plate 2, and a fixing screw 14 for fixing the punch pin 13 is arranged on the clamping plate 3, so that the punch pin 13 can be quickly replaced.

As shown in fig. 3, in this embodiment, at least two opposite side surfaces of the clamping plate 3 are provided with plate-removing hooks 15, and the number of the plate-removing hooks on each side surface is not less than two.

And a plurality of the plate-removing hooks 15 can be uniformly distributed on each side surface of the clamping plate 3.

Or at least two plate-removing hooks 15 are arranged on each side surface of the clamping plate 3.

Make backplate 4 and take off flitch 5 each position atress the same promptly, avoid the slope can.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
