Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described, but protection scope of the present invention is not limited thereto.
Embodiment 1
As Figure 1-5, a kind of automatic mould unloading mould on one-way press, comprises upper parallels 1 from top to bottom, die sleeve 4, gripper shoe 9 and base plate 11, die sleeve 4 center is provided with die cavity 3, seaming chuck 2 and push-down head 7 is provided with in die cavity 3, gripper shoe 9 is provided with the hole 21(passed for support elastomer 5 and supports elastomer 5 and hole 21 matched in clearance), supporting elastomer 5(, to support elastomer 5 be three, evenly announces along gripper shoe 9 circumference) two ends to be up and down separately fixed on die sleeve 4 and base plate 11 (distance between original state die sleeve 4 lower end and gripper shoe 9 be less than support elastomer 5 deformation length but be not less than the loose height filled of powder), gripper shoe 9 position corresponding below die cavity 3 is provided with through hole 13, through hole 13 upper inner is provided with inner convex platform 15, the bottom of push-down head 7 is provided with outer lug boss 14, outer lug boss 14 is positioned at through hole 13, and outer lug boss 14 is positioned at the below of inner convex platform 15, the external diameter of outer lug boss 14 is greater than the internal diameter of inner convex platform 15, base plate 11 place below through hole 13 is fixed with one end of mould unloading elastomer 8, the other end of mould unloading elastomer 8 be fixed on push-down head 7 (mould unloading elastomer original state has certain precompression in bottom, and there is the elastic deformation coefficient that finished product is ejected from die sleeve, seaming chuck height is not less than in the deformation length of pressing process, in original state, the length of push-down head protrusion gripper shoe part is not less than the height of die sleeve, and the length sum that seaming chuck thickness and push-down head protrude gripper shoe deducts push-down head lower end equals die sleeve height apart from the height of plate upper surface).
Described gripper shoe 9 is provided with cavity 18, first passage groove 19, second channel groove 16, first snap fit 6 and the second snap fit 17, first passage groove 19 is positioned at the top of cavity 18 and is communicated with cavity 18, and second channel groove 16 is positioned at the right side side of cavity 18 and is communicated with cavity 18; Cavity 18 left side wall is abutted against clamping elastomer 12, the right side of clamping elastomer 12 and the left end of the second snap fit 17 are abutted against, the upper end of the first snap fit 6 is fixed on the lower end of die sleeve, described first snap fit 6 has the first station and the second station, when the first snap fit 6 is in the first station, first snap fit is positioned at above first passage groove 19, when the first snap fit 6 is in the second station, the lower end of the first snap fit 6 is passed first passage groove 19 and is connected together with the second snap fit 17 upper end, and the right-hand member of the second snap fit 17 passes second channel groove 16 and stretches out outside gripper shoe 9.
Described first snap fit 6 is cylindric, and the left side of the first snap fit 6 lower end has the first groove 20; Described second snap fit 10 is L shape, and the right side of upper end, L shape vertical portion 1001 is provided with second projection 10, the L shape horizontal part 1002 suitable with the first groove 20 and passes second channel groove 16 and stretch out outside gripper shoe 9.
The left side of described first snap fit 6 lower end is milled with the first inclined-plane 601, and the upper right corner of described second projection 10 is milled with the second inclined-plane 101; First inclined-plane 601 parallel with the second inclined-plane 101 (by the setting on the first inclined-plane 601 and the second inclined-plane 101, when can make pressing die material, manually need not protrude the position of gripper shoe 9 according to the second snap fit 17).
Support elastomer 9 in the present embodiment, clamping elastomer 12, mould unloading elastomer 8 are spring.
In the present embodiment, die sleeve 4 is for being provided with the cylinder of upper and lower through die cavity 3, (the length sum that original state seaming chuck thickness and push-down head protrude gripper shoe deducts push-down head lower end equals die cavity 3 height apart from the height of plate upper surface to the molding thickness of the thickness determination powder of upper parallels 1, the thickness of upper parallels 1 determines the molding thickness that powder is final, i.e. design thickness), upper parallels 1 uses in pairs, uses the upper parallels 1 of different-thickness can realize the compressing of multi-thickness finished product.
The automatic mould unloading mold use process of the present embodiment is as follows:
(1) die-filling: be evenly placed in by powder to be pressed in die cavity 3, seaming chuck 2 is pressed into die cavity 3, parallels 1 on seaming chuck 2 bilateral symmetry is placed, is placed in the mould assembled on one-way press work top;
(2) suppress: start one-way press, press upper pressure head moves down thus exerts pressure to seaming chuck 2, seaming chuck 2 continues to enter in die cavity 3, meanwhile, support elastomer 5 and compress, die sleeve 4 moves down, under the effect of mould unloading elastomer 8, push-down head 7 limit continues to enter die cavity 3, realizes bi-directional synchronization compacting, until press upper pressure head and upper parallels 1 rigid contact, push-down head 7 and base plate 11 rigid contact, die sleeve 4 lower end and gripper shoe 9 rigid contact; At the end of compacting, the first snap fit 6 and the second snap fit card 17 are connected together, die sleeve 4 and gripper shoe 9 are linked together;
(3) mould unloading: press upper pressure head moves release, because die sleeve 4 and gripper shoe 9 are joined together, now mould unloading elastomer 8 progressively recovers distortion, continue finished product to eject die cavity 3 by push-down head 7, treat that press upper pressure head and mould seaming chuck 7 depart from, mould can be taken out from compressor operation table top, take finished product away, press the position that the second snap fit 17 protrudes gripper shoe 9, first snap fit 6 and the second snap fit 17 depart from, and die sleeve 4 and gripper shoe 9 depart from, and restPose, repeat step (1), implement again compressing.
