A kind of Collapsible mould
This utility model belongs to metal-working plant field, more particularly, to a kind of Collapsible mould for stamping machine.
Stamping machine is the common equipment of metalwork processing, is provided with for carrying out stamping forming punching to workpiece on stamping machine
Compression mould, and stamping mold is requisite vitals, the quality of stamping machine, production efficiency on stamping machine in punching production
And production cost etc., all there is direct relation with the design and manufacture of stamping mold.In prior art, in punch process mistake repeatedly
There is positioning and forbidden in Cheng Zhong, the laminating of the upper die and lower die of stamping mold, easily produce the problem of skew, affect the product of workpiece
Quality；And the lead column and pilot hole for cooperating is set on upper bolster and die shoe, when lead column stretches into pilot hole, it
Between form face contact, easily cause abrasion or damage, it is when the lead column damaged or pilot hole are keeped in repair and changed, generally right
Whole die shoe or upper bolster are changed, and processing cost is also increased while wasting time and energy.Additionally, the lead column for setting
It is highly fixed with pilot hole, a kind of workpiece of thickness can only be processed, range of application is narrower.
The content of the invention
Problem to be solved in the utility model is to provide a kind of positioning conveniently, and it is convenient that maintenance is changed, and cost is reduced, scalable
Highly, the Collapsible mould having wide range of applications.
To solve above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of Collapsible mould, including it is upper
Mould, lower mould and lengthening block, the upper mould are arranged at upper mounting plate bottom centre position, and the upper mounting plate is arranged at upper bolster bottom
Portion；The lower mould is arranged at lower installation board top center, and the lower installation board is arranged at the top of die shoe；The upper installation
Plate bottom is provided with lead column, and the lead column is symmetricly set in mould both sides；Correspondence lead column position at the top of the lower installation board
Install and be equipped with the pilot hole being matched therewith；The guiding column bottom is provided with screwed hole, is provided with and spiral shell on the lengthening block
The threaded post that pit is engaged, is made lengthening block be formed with lead column and is detachably connected.
The upper mould, upper mounting plate and upper bolster are to be detachably connected.
The lower mould, lower installation board and die shoe are to be detachably connected.
The lengthening block is identical with column diameter is oriented to.
Due to adopting above-mentioned technical proposal, (1) is entered in upper die and lower die punching press by the cooperation of lead column and pilot hole
Row positioning, and lead column and pilot hole are respectively arranged on upper mounting plate and lower installation board, when lead column or pilot hole have abrasion
In the case of, upper mounting plate or lower installation board can be pulled down and be repaired or replaced, not interfere with the use of other structures, be improved
While maintenance and replacing efficiency, production cost is reduced；(2) lead column is connected with block is lengthened by the screwed hole of bottom, and one
Fermentation lengthens block and is located at end more easy to wear, can directly change lengthening block after its abrasion, convenient and swift；On the other hand, lengthen
Block may be configured as different-thickness, during work, as needed install respective thickness lengthening block come adjust lead column height, adapt to plus
The workpiece of work different-thickness.
The beneficial effects of the utility model are：Convenient with positioning, it is convenient that maintenance is changed, and cost is reduced, adjustable-height,
The advantage having wide range of applications.
Description of the drawings
This utility model, advantage of the present utility model and realization are specifically described below with reference to accompanying drawing and with reference to example
Mode will become apparent from, and wherein shown in accompanying drawing, content is only used for explanation of the present utility model, and is not constituted to this reality
With the new restriction gone up in all senses, in the accompanying drawings：
Fig. 1 is structural representation of the present utility model
1st, upper mould 2, lower mould 3, lengthening block
4th, upper mounting plate 5, upper bolster 6, lower installation board
7th, die shoe 8, lead column 9, pilot hole
10th, screwed hole 11, threaded post
As shown in figure 1, a kind of Collapsible mould of this utility model, including upper mould 1, lower mould 2 and lengthening block 3, the upper mould 1
4 bottom centre position of upper mounting plate is arranged at, the upper mounting plate 4 is arranged at 5 bottom of upper bolster；The lower mould 2 is arranged at down
6 top center of installing plate, the lower installation board 6 are arranged at the top of die shoe 7；4 bottom of the upper mounting plate is provided with leads
To post 8, the lead column 8 is symmetricly set in 1 both sides of mould；At the top of the lower installation board 6 correspondence lead column 8 position be provided with
The pilot hole 9 which is engaged；8 bottom of the lead column is provided with screwed hole 10, is provided with and screwed hole 10 on the lengthening block 3
The threaded post 11 being engaged, is made lengthening block 3 be formed with lead column 8 and is detachably connected；The upper mould 1, upper mounting plate 4 and upper bolster
5 is to be detachably connected；The lower mould 2, lower installation board 6 and die shoe 7 are to be detachably connected；The lengthening block 3 is straight with lead column 8
Footpath is identical.
Positioned in upper mould 1 and lower 2 punching press of mould by the cooperation of lead column 8 and pilot hole 9, and lead column 8 and led
It is respectively arranged on upper mounting plate 4 and lower installation board 6 to hole 9, in the case that lead column 8 or pilot hole 9 have abrasion, can will be upper
Installing plate 4 or lower installation board 6 are pulled down and are repaired or replaced, and do not interfere with the use of other structures, are improved maintenance and are changed effect
While rate, production cost is reduced；Lead column 8 is connected with block 3 is lengthened by the screwed hole 11 of bottom, and a fermentation lengthens block 3
Positioned at end more easy to wear, lengthening block 3 after its abrasion, can be directly changed, it is convenient and swift；On the other hand, lengthen block 3 to arrange
For different-thickness, during work, the lengthening block of respective thickness is installed as needed to adjust 8 height of lead column, processing is adapted to different
The workpiece of thickness.
Above embodiment of the present utility model is described in detail, but the content has been only of the present utility model preferable
Embodiment, it is impossible to be considered as limiting practical range of the present utility model.All impartial changes made according to this utility model scope
