The specific embodiment

Therefore the preferred example of the mould structure of bottom dead centre moment back pressure described in the utility model, do not limit protection domain of the present utility model below.

With reference to Fig. 1, a kind of mould structure of bottom dead centre moment back pressure is provided, comprise upper bolster 1, be installed in successively upper padding plate 2 and the upper mounted plate 3 of upper bolster 1 bottom, die shoe 4, be installed in successively first lower bolster 5 on die shoe 4 tops, the second lower bolster 6 and concave template 7, also comprise, be installed in forming terrace die 9 and the upper push-rod 10 of upper mounted plate 3, be installed in die shoe 4, the first lower bolster 5, lower device for discharging 11 in the second lower bolster 6 and concave template 7, be installed in the supporting plate 12 in the first lower bolster 5, the transition push rod 13 that runs through described the second lower bolster 6, be installed in concave template 7 and be set in the shaping push rod 14 on transition push rod 13, and the lower push rod 15 that runs through described concave template 7 and the second lower bolster 6 and be connected with supporting plate 12, the position of described lower push rod 15 is corresponding with upper push-rod 10, described lower device for discharging 11 is in transmission connection with supporting plate 12, described die shoe 4 is provided with the limited step 16 matching with supporting plate 12.During work, when supporting plate 12 comes downwards to limited step 16 place, described in limited step 16 blocks, supporting plate 12 continues descending, now forming terrace die 9 just goes downwards to bottom dead centre, shaping push rod 14 contacts with circle wing rigidity, produces moment back pressure, thereby realize, flattens circle wing top, force a small amount of excess stock to reflux, and then it is contour to realize each circle wing.Justify like this each circle wing of wing radiator and realize bottom dead centre moment back pressure and contact with rigidity, thus guarantee radiator each to justify wing contour.No longer need machined excision operation, save work step in man-hour, improve the production efficiency of enterprise, reduced production cost.

Furthermore, also comprise loading and unloading material device 8, described loading and unloading material device 8 comprises the loading and unloading material spring 81 being installed in cope match-plate pattern 1, be installed in the loading and unloading material push rod 82 in upper padding plate 2 and be installed in the loading and unloading material pushing block 83 in forming terrace die 9, described loading and unloading material push rod 82 one end connect loading and unloading material spring 81, the other end connects loading and unloading material pushing block 83, and loading and unloading material push rod 82 and loading and unloading material pushing block 83 move downward under 81 effects of loading and unloading material spring, thereby realizes the de-material of forming terrace die 9.

Furthermore, described lower device for discharging 11 comprises and is installed in concave template 7 and is set in the lower discharging jacking block 111 on shaping push rod 14, pass the lower discharging push rod 112 that described supporting plate 12 and the second lower bolster 6 are connected with lower discharging jacking block 111, and be installed in first time discharging spring 113 and the second time discharging spring 114 in die shoe 4, described first time discharging spring 113 is connected with supporting plate 12, the position of described second time discharging spring 114 is corresponding with lower discharging push rod 112, supporting plate 12 moves upward under the effect of first time discharging spring 113, lower discharging push rod 112 moves upward under the effect of second time discharging spring 114, thereby realize the de-material of counterdie.

Furthermore, fixed plate is also equiped with the guide pillar 17 for correcting forming terrace die 9, in described concave template 7 and the second lower bolster 6, offers the guide pillar hole 18 of matching with guide pillar 17.Forming terrace die 9 passes through guide pillar 17 correctings, thereby has guaranteed that forming terrace die 9 can not be offset in forming process, operates steadily on forming terrace die 9.

Operation principle of the present utility model is:

Forcing press drives descending, and first upper push-rod 10 pushes down lower push rod 15, makes lower push rod 15 push down supporting plate 12 descending, and now, shaping push rod 14 and transition push rod 13 are because of gravity and along with supporting plate 12 DL synchronizations.Subsequently, it is descending together that forming terrace die 9 is pushed down workpiece 19, thereby drive lower discharging jacking block 111 and lower discharging push rod 112 descending, material enters in the circular hole that shaping push rod 14 exits, and forms step by step circle wing, and forming terrace die 9 continues descending, circle wing is constantly elongated, in circle wing forming process, itself and shaping push rod 14 can not form back pressure, are therefore very beneficial for the growth of circle wing.Along with mould continues descending, when supporting plate 12 lower surfaces touch the limited step 16 of die shoe 4, owing to being subject to the block effect of limited step 16, supporting plate 12, transition push rod 13 and 14 stop motions of shaping push rod, meanwhile, forming terrace die 9 goes downwards to bottom dead centre, shaping push rod 14 produces moment back pressure with circle wing, flatten circle wing top, force a small amount of excess stock to reflux, thereby it is contour to realize each circle wing.

Forcing press drives up subsequently, under the effect of first time discharging spring 113 and the second discharging spring 114, supporting plate 12, transition push rod 13, shaping push rod 14, lower push rod 15, upper push-rod 10, lower discharging jacking block 111 are up together with lower discharging push rod 112, until complete workpiece 19, eject completely, then lower push rod 15 and upper push-rod 10 depart from.When mould is up to top dead-centre, under 81 effects of loading and unloading material spring, loading and unloading material push rod 82 and loading and unloading material pushing block 83 are descending, release and are bonded at the workpiece 19 on forming terrace die 9, and whole stroke finishes.With reference to Fig. 2, Fig. 2 shows the structure of be processed into product, above-described embodiment is just enumerated a kind of shape product, also can the parts of mould be modified or be changed according to the shape of other products of the same type, thereby meet the processing request of other products of the same type.Have constant product quality, yields is high, and mold repair is simply readily removable, easy manufacture simple in structure, and the production debugging mould time is short, production efficiency advantages of higher.

Above-described embodiment is preferably embodiment of the utility model; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify; all should be equivalent substitute mode, within being included in protection domain of the present utility model.
