Abstract
The invention relates to a porous tablet mould and aims to solve the problem that the traditional tablet mould is not suitable for large-pressure tablet presses. The porous tablet mould comprises an upper mould, a middle mould and a lower mould, wherein the upper mould comprises an upper punch handle, a portal frame, an upper punch and an upper punch core bar. The upper punch handle is fixed at the top part of a groove block; a lower punch is fixed at the lower part of the groove block; the crossbeam of the portal frame is sleeved in the groove block; the upper punch core bar is fixed on the crossbeam of the portal frame and sleeved in the upper punch; the lower mould comprises a lower punch handle, a lower punch core bar and the lower punch; the lower punch handle is sleeved with a core bar seat; a lower punch core bar liner plate, a lower punch core bar fielded panel, a lower punch liner plate and a lower punch fielded panel are arranged in the core bar seat from bottom to top; the lower punch handle is fixed on the lower punch fielded panel; the lower punch core bar is embedded on the lower punch core bar fielded panel; a middle mould gasket is arranged between the middle mould and the core bar seat; the middle mould is further sleeved with a middle mould pressing ring; and a positioning rod is arranged between the upper mould and the lower mould. The porous tablet mould provided by the invention can overcome the disadvantages of relatively large tablet pressure and tablet ejection force during tablet pressing, and meet the process requirements of tablet pressing.
Description
Technical field
The present invention relates to a kind of tablet mould, specifically porous tablet mould.
Background technology
After porous annular tablet particularly needed the porous tablet of big pressure, big specification to occur at present, existing tablet mould structure was not suitable for the tablet press machine of the big specification of big pressure.
Summary of the invention
The object of the present invention is to provide porous tablet mould, solve the problem that present tablet mould is not suitable for the big specification tablet press machine of big pressure.
The technical solution adopted for the present invention to solve the technical problems is: porous tablet mould, comprise patrix, middle mould and counterdie, it is characterized in that, described patrix comprises die shank, portal frame, upper punch and upper punch core bar, last die shank is fixed on a geosynclinal block top, and the geosynclinal block bottom is fixed with upper punch, and the crossbeam of portal frame is set in the geosynclinal block, portal frame can be in geosynclinal block vertically slides, and the upper punch core bar is fixed on the crossbeam of portal frame and is placed in the upper punch; Described counterdie comprises die shank, following to core bar and low punch down, be arranged with a core bar seat on the following die shank, be respectively equipped with down from the bottom to top in the core bar seat towards the core bar backing plate, down towards core bar panelling, low punch backing plate and low punch panelling, following die shank passes down towards the core bar panelling, is connected with the low punch panelling towards the core bar backing plate down, low punch is set on the low punch panelling, down passes low punch towards core bar and is set in down on the core bar panelling and is fixed in the core bar seat; Die-cushion circle in being provided with between middle mould and the core bar seat, the middle mould outside also is arranged with mold pressing circle in, and the top of low punch is arranged in the material chamber of mould; Be provided with backstay between the upper die and lower die, the two ends of backstay are respectively equipped with location-plate and following location-plate; Described upper punch core bar matches with low punch, and the upper punch core bar is no less than four.
The invention has the beneficial effects as follows: can overcome compressed tablets compression force and all bigger characteristics of top flat power, can meet the tablet press technological requirement again.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: die shank on 1,2 portal frames, 3 upper punch, 4 upper punch core bars, 5 geosynclinal blocks, 6 times die shanks, 7 times towards core bar, 8 low punches, 9 core bar seats, 10 times 11 times towards the core bar panelling towards the core bar backing plate, 12 low punch backing plates, 13 low punch panellings, mould in 14,141 material chambeies, die-cushion circle in 15, mold pressing circle in 16,17 backstays, location-plate on 18,19 times location-plates
The specific embodiment
As shown in Figure 1, porous tablet mould, comprise patrix, middle mould and counterdie, described patrix comprises die shank 1, portal frame 2, upper punch 3 and upper punch core bar 4, last die shank 1 is fixed on a geosynclinal block 5 tops, and geosynclinal block 5 bottoms are fixed with upper punch 3, and the crossbeam of portal frame 2 is set in the geosynclinal block 5, portal frame 2 can be in geosynclinal block 5 vertically slides, and upper punch core bar 4 is fixed on the crossbeam of portal frame 2 and is placed in the upper punch 3; Described counterdie comprises die shank 6, following to core bar 7 and low punch 8 down, be arranged with a core bar seat 9 on the following die shank 6, be respectively equipped with down from the bottom to top in the core bar seat 9 towards core bar backing plate 10, down towards core bar panelling 11, low punch backing plate 12 and low punch panelling 13, following die shank 6 passes down towards core bar panelling 11, is connected with low punch panelling 13 towards core bar backing plate 10 down, low punch 8 is set on the low punch panelling 13, down passes low punch 8 towards core bar 7 and is set in down on core bar panelling 11 and is fixed in the core bar seat 9; Die-cushion circle 15 in being provided with between middle mould 14 and the core bar seat 9, middle mould 14 outsides also are arranged with mold pressing circle 16 in, and the top of low punch 8 is arranged in the material chamber 141 of mould 14; Be provided with backstay 17 between the upper die and lower die, the two ends of backstay 17 are respectively equipped with location-plate 18 and following location-plate 19; Described upper punch core bar 4 matches with low punch 8, and upper punch core bar 4 is no less than four.
Operation principle: when material chamber 141 is full of material, the lever segment of tablet press machine drives upward, and die shank 1 moves downward, when portal frame 2 arrives location-plate 19, portal frame 2 and 4 stop motions of upper punch core bar, last die shank 1 continues to move downward with geosynclinal block 5, upper punch 3, upper punch 3 enters material chamber 141, continues to move down the tablet press work of finishing; The compacting finish after under the drive of equipment, last die shank 1 up moving, following die shank 6 is up, this at present towards core bar 7, down towards core bar backing plate 10, motionless towards core bar panelling 11 down, low punch backing plate 12, low punch panelling 13, low punch 8 are up under the drive of die shank 6 down, and tablet is ejected material chamber 141; Finish when pay-off is released tablet to material chamber 141 and feed in raw material again, carry out compressing tablet, top flat work once more.So the compressing tablet process is finished in circulation.
