The specific embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.In the following detailed description, only some one exemplary embodiment of the present utility model has been described by the mode of explanation.Undoubtedly, those of ordinary skill in the art can recognize, under the situation that does not depart from spirit and scope of the present utility model, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used to limit the protection domain of claim.
As shown in Figure 1, floating cavity die, comprise the upper bolster 1 and the die shoe 2 that are provided with in opposite directions, the upper surface of described die shoe 2 is provided with die backing plate 3, be installed with fixed head guide pillar 4 on the described die backing plate 3, be set with the fixed head guide pin bushing 5 that can slide up and down along described fixed head guide pillar 4 on the described fixed head guide pillar 4, be installed with die block 6 on the described fixed head guide pin bushing 5, be installed with die 7 on the described die block 6, be provided with the fixed head elastic force apparatus that fixed head is upspring between described die block 6 and the described die backing plate 3, described fixed head elastic force apparatus is a fixed head spring 10;
Be provided with casting die device 8 between described upper bolster 1 and the described die 7, be provided with the discharging screw 16 that both are linked together between the lower surface of described casting die device 8 and described upper bolster 1, discharging screw 16 upper sleeve throughs casting die device 8 elastic force apparatus that the elasticity downforce is provided to the casting die device, and described casting die device 8 elastic force apparatus are casting die device spring 11; Also be installed with the punch 9 that passes described casting die device 8 and extend on the lower surface of described upper bolster 1 downwards, on the lower surface of upper bolster 1, be provided with convex mould pad 13, be installed with punch retainer 14 on the convex mould pad 13, described punch 9 passes described punch retainer 14 and is fixedly mounted on the described convex mould pad 13.
Described die backing plate 3 is provided with the material spilling hole (not shown), and described die shoe 2 is provided with the waste material box 12 that is communicated with described material spilling hole, and the waste material that punching produces can enter into waste material box 12 by material spilling hole.
Adopt four stations during the design of this mould, totally four of dies 7 because the pitch-row limit is too near, for proof strength is not inlayed die case, and adopt Cr12MoV integral body to insert.Die 7 forwards are fixed on the die block 6, be die backing plate 3 below, (when product 15 is put into die 7) has the 1mm gap in vain between the two, with fixed head guide pillar 4 and fixed head guide pin bushing 5 guiding, be provided with spring between die block 6 and the die backing plate 3, from die backing plate 3, die backing plate 3 is fixed on the die shoe 2 described spring with die block 6 bullets.Upper bolster 1 is the punching conventional structure, adopts 45# steel part casting die device 8 and thick blanks perforating die, is not giving unnecessary details at this.
As shown in Figure 2, mould is contained on the press, during work, product 15 is put into die 7 from the side, and blinking scrap is last time pushed material spilling hole, collects with waste material box 12; Product 15 usefulness holes (alignment pin) and profile location; When upper bolster 1 fell, casting die device 8 touched the top airfoil of product 15 earlier, drives die 7 and die block 6 and move downward together under the spring force effect, touched die backing plate 3 to the lower aerofoil of product 15; Product 15, die 7, die block 6 and die backing plate 3 are very close to each other up and down at this moment, like an integral body; Follow in the thick material boss mould 9 incision dies 7.At press when bottom dead centre oppositely moves upward, thick material boss mould 9 breaks away from die 7 earlier under the effect of casting die device 8, then casting die device 8 also breaks away from die 7, and die 7 and die block 6 move upward under the effect of spring, break away from die backing plate 3, promptly product 15 lower surfaces break away from die backing plate 3.Product 15 takes out from die 7 like this, finishes the stamping-out process one time.
This mould is when stamping-out, and product 15 will wrap on the die 7 and be close to die backing plate 3, and each part can not be gapped.Preventing that die 7 is suspended in the space and crushed or pressure break, therefore design and will note some when making:
(1) die backing plate 3, casting die device 8, die 7 must with product 15 digital-to-analogue symbol types, between each part unsettled gap can not be arranged, improve each part lapping-in rate during manufacturing;
(2) die 7 and die block 6 be at spring action subiculum time-out, and holding up height can not thick greater than the twice material (containing product 15), and promptly product 15 is put into die 7, can not have waste material not enter waste material box 12 below;
(3) casting die device spring 11 pressure and stroke are greater than die block 6 springs, and casting die device 8 is wanted to push down die 7 and die block 6 earlier during work.In case press when work, die 7 is suspended in the air.
(4) it is enough big that die backing plate 3 and die shoe 2 leak the waste material space, can not have waste material to be stuck between die 7 and the die backing plate 3, when only needing product 15 to put into die 7, just can shift onto in the material spilling hole.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
