Description
Technical Field
The utility model relates to a mould field, in particular to die-cut mould of multipurpose that lower mould was easily changed.
Background
The existing punching die easily causes the damage of a local knife edge of a punching part in the repeated punching operation process. After each knife edge is damaged, the whole lower die needs to be disassembled and then maintained and replaced, so that the maintenance period of the die is too long, and the cost is too high. In addition, current processing mode has decided that every style of product all needs a pair mould punching press, and punching press A style of product needs a pair mould, and punching press B style of product needs a pair mould, but two style of products annual output is all little, opens two pairs of moulds and leads to the fact the idle waste of mould unavoidably.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a to prior art's defect, provide one kind can carry out quick replacement and be applicable to the die-cut mould of multiple product processing to lower bolster fragile position.
In order to solve the technical problem, the utility model provides a technical scheme as follows:
the utility model provides a die-cut mould of multipurpose of lower mould easy change, includes mould and lower mould, go up the mould including upper cover plate, upper die base, upper padding plate, punch holder, cope match-plate pattern and the interior piece of taking off that from top to bottom set gradually, the lower mould is including taking off board, lower bolster, lower plate and die holder outward that from top to bottom set gradually, the lower plate includes lower plate main part and cutting part, its characterized in that: the lower splint comprises a lower splint body and is characterized in that slide fixing grooves are formed in the lower splint body, cutting portions are detachably arranged on the slide fixing grooves, the number of the slide fixing grooves is two, the two sliding fixing grooves are respectively a first slide fixing groove and a second slide fixing groove, a first cutting portion is arranged in the first slide fixing groove, and a second cutting portion is arranged in the second slide fixing groove.
Further, the first cutting portion is rectangular, and the second cutting portion is approximately elliptical.
Furthermore, clearance fit is formed between the first cutting portion and the first sliding fixing groove and between the second cutting portion and the second sliding fixing groove, and the clearance is 0.02 mm.
Further, be provided with first fastening screw hole and second fastening screw hole on first cutting portion and the second cutting portion respectively, first cutting portion and second cutting portion pass through first fastening screw hole and second fastening screw hole are fixed on first slip fixed slot and second slip fixed slot.
Compared with the prior art, the beneficial effects of the utility model are that: 1. the traditional integral lower clamping plate is set into a detachable split lower clamping plate, the cutting part which is originally easy to damage can be movably embedded in the sliding fixing groove of the lower clamping plate, when the cutting part is damaged and needs to be replaced, the whole lower die does not need to be detached for replacement, and the cutting part only needs to be detached from the sliding fixing groove on the lower clamping plate, so that the maintenance cost of the lower die is saved, and the replacement and maintenance time is shortened; 2. two or even a plurality of sliding fixing grooves suitable for different cutting parts are formed in the lower clamping plate, so that products in different shapes can be punched, and particularly when the lower clamping plate is used for products with low annual output, the cost of forming a pair of dies is high, so that two or even more pairs of dies are combined into one die to be formed, the die manufacturing cost can be reduced, and the die storage space is saved.

Detailed Description
In order to deepen the understanding of the present invention, we will make further details of the present invention with reference to the drawings, and this embodiment is only used to explain the present invention, and does not constitute a limitation to the protection scope of the present invention.
Fig. 1-4 show a die-cut mould of multipurpose that lower mould was easily changed, including last mould and lower mould, it includes upper cover plate 1 that from top to bottom sets gradually to go up the mould, upper die base 2, upper padding plate 3, punch holder 4, cope match-plate pattern 5 and interior stripping block 6, the lower mould is including the outer stripping plate 7 that from top to bottom sets gradually, lower bolster 9, lower plate 8 and die holder 10, lower plate 8 includes lower plate main part 81 and cutting part, be provided with the slide fixing groove on the lower plate main part 81, the cutting part sets up on the slide fixing groove with the detachable mode, the quantity of slide fixing groove is two, be first slide fixing groove 82 and second slide fixing groove 83 respectively, be provided with first cutting part 84 in first slide fixing groove 82, be provided with second cutting part 85 in second slide fixing groove 83.
Preferably, the first cutting portion 84 is rectangular, and the second cutting portion 85 is approximately elliptical; the first cutting part 84 is in clearance fit with the first sliding fixing groove 82, and the second cutting part 85 is in clearance fit with the second sliding fixing groove 83, wherein the clearance is 0.02 mm; the first and second cutting portions 84 and 85 are provided with first and second fastening screw holes 86 and 87, respectively, and the first and second cutting portions 84 and 85 are fixed to the first and second slide fixing grooves 82 and 83 by the first and second fastening screw holes 86 and 87.
