Abstract
The utility model discloses a kind of pressure automatic discharging mould, comprise die combination and lower die combination, upper die combination comprises upper bolster, holding pad and forming convax mould, and holding pad is suspended on upper bolster by pull bar; Lower die combination comprises die shoe, molding concave die and lead; The side of holding pad is provided with limited block, upper bolster is also provided with pulling block, molding concave die is provided with lower drawing block.During production, steel pipe blank is placed in molding concave die, forming convax mould moves down with upper die combination and inserts in steel pipe blank, realize the punching press reaming to steel pipe blank, after reaming completes, upper die combination is moved, steel pipe part fixes to follow on forming convax mould and moves, and now because holding pad is motionless, when steel pipe part rise to contact with holding pad time, steel pipe part is separated with forming convax mould under the barrier force effect of holding pad, part removal is convenient and swift, and production efficiency is high, and in knockout course, steel pipe part there will not be the problem of stress deformation.
Description
Technical field
The utility model relates to a kind of mould, particularly a kind of diel.
Background technology
When adopting diel to carry out reaming to steel pipe part; terminate in patrix return process in reaming; steel pipe part often there will be fixing on forming convax mould; make part removal difficulty; need workman to beat steel pipe part with workpiece just to come off punch, cause that production efficiency is low, part is easily because knocking the problem of deformed damaged.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of pressure automatic discharging mould, to solve existing diel to easily occurring steel pipe and the forming convax mould stuck problem causing the demoulding difficulty during steel pipe reaming.
The utility model pressure automatic discharging mould, comprise die combination and lower die combination, the forming convax mould that described upper die combination comprises upper bolster, holding pad and is vertically fixed on upper bolster, described forming convax mould and holding pad slide up and down cooperation, described holding pad is suspended on upper bolster by pull bar, and described pull bar and holding pad slide up and down cooperation;
Described lower die combination comprises die shoe, be fixed on the molding concave die on die shoe and be fixed on die shoe and slide up and down with upper bolster the lead coordinated;
The side of described holding pad is provided with and promotes by spring the limited block that transversely stretches, the upper surface of described limited block is horizontal plane, lower surface is tapered plane, described upper bolster is also provided with pulling block, the lower end of described upper pulling block is provided with the lower eave tile coordinated with limited block lower end tapered plane, described molding concave die is provided with lower drawing block, and the upper end of described lower drawing block is provided with the lower eave tile coordinated with limited block upper end horizontal plane.
Further, described holding pad is also provided with the guide post sliding up and down with upper bolster and coordinate.
The beneficial effects of the utility model:
The utility model pressure automatic discharging mould, during production, steel pipe blank is placed in molding concave die, forming convax mould moves down with upper die combination and inserts in steel pipe blank, realize the punching press reaming to steel pipe blank, after reaming completes, upper die combination is moved, steel pipe part fixes to follow on forming convax mould and moves, and now because the limited block on holding pad is caught on by the lower drawing block on molding concave die, holding pad is motionless, when steel pipe part rise to contact with holding pad time, steel pipe part is separated with forming convax mould under the barrier force effect of holding pad, part removal is convenient and swift, production efficiency is high, and steel pipe part there will not be the problem of stress deformation in knockout course.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model pressure automatic discharging mould;
Fig. 2 is that in Fig. 1, pressure automatic discharging mould is concealing the perspective view under molding concave die state;
Fig. 3 is that in Fig. 1, pressure automatic discharging mould is concealing the perspective view under lower drawing block state.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the present embodiment pressure automatic discharging mould, comprise die combination and lower die combination, the forming convax mould 3 that described upper die combination comprises upper bolster 1, holding pad 2 and is vertically fixed on upper bolster, described forming convax mould and holding pad slide up and down cooperation, described holding pad is suspended on upper bolster by pull bar 4, and described pull bar and holding pad slide up and down cooperation;
Described lower die combination comprises die shoe 5, be fixed on the molding concave die 6 on die shoe and be fixed on die shoe and slide up and down with upper bolster the lead 7 coordinated;
The side of described holding pad is provided with and promotes by spring the limited block 8 that transversely stretches, the upper surface of described limited block is horizontal plane, lower surface is tapered plane, described upper bolster is also provided with pulling block 9, the lower end of described upper pulling block is provided with the lower eave tile coordinated with limited block lower end tapered plane, described molding concave die is provided with lower drawing block 10, the upper end of described lower drawing block is provided with the lower eave tile coordinated with limited block upper end horizontal plane.
The course of work of the present embodiment pressure automatic discharging mould is as follows:
First, be placed on by steel pipe blank in molding concave die 6, then go up die combination and move down, forming convax mould 3 is pressed in steel pipe blank and realizes steel pipe reaming; Then after reaming terminates, upper die combination is moved, steel pipe part fixes to follow on forming convax mould 3 and moves simultaneously, and now because the limited block 8 on holding pad 2 is caught on by the lower drawing block 10 on molding concave die 6, holding pad 2 transfixion, when steel pipe part rise to contact with holding pad 2 time, steel pipe part is separated with forming convax mould 3 under the barrier force effect of holding pad 2; Finally go up in die combination continuation and move, the upper pulling block 9 be now fixed on upper bolster 1 contacts with limited block 8, the inclined-plane of upper pulling block 9 lower end makes limited block 8 shrink to limited block 8 applied thrust, thus limited block 8 is separated with lower drawing block 10, simultaneously holding pad 2 under the effect of pull bar 4 together with other part in upper die combination on be moved back into original position, can carry out piece installing reaming next time, and steel pipe workpieces ejects from molding concave die 6 by the push rod 12 be arranged on below die shoe 5.
The present embodiment pressure automatic discharging mould achieves automatically being separated of steel pipe part and forming convax mould, and part removal is convenient and swift, and production efficiency is high, and in knockout course, steel pipe part there will not be the problem of stress deformation.
As the improvement to the present embodiment, described holding pad 2 is also provided with the guide post 11 sliding up and down with upper bolster and coordinate, is led by the motion of guide post 11 pairs of holding pads 2, be conducive to making steel pipe part end face stress equalization, demoulding quality can be improved.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
