In the time of the compressing end of product, the guide rail 75 of wedge sliding mechanism 7 is pressed in gear and adjusts on swivel nut 11 end faces, thereby limit the forming height that step needs, thereby just push down sliding bar 711 and overcome spring 712 power and oppress by force roller 79 and open guide rail 75 and complete the demoulding and adjust screw rod 61, after completing, sliding bar 711 relies on spring 712 expansion force returns, the recessed float plate 2 of touching supports and under cylinder 5 active forces, returns to desired location before compacting after the demoulding completes before and after symmetrical, prepares next working procedure.
The operation principle explanation of this moulding press.Taking compacting EFD series of products as example, fixing of the forming frame is on press, after adjusting work loading height and formed product size, start press, press drives upper and lower two movable parts of mould bases to make upper and lower symmetric motion (base 13, in fixing, beam slab 1 is fixing, upper die plate 8, moulding platen 64, bearing plate 14 and core bar 9 are upper and lower movable part, die float plate also can be up and down along slide post 15, wherein, upper driver part drives upper die plate 8 to move by upper connecting base 81, lower driver part drives bearing plate 14 to move by lower connecting base 140), 360 ° is one-period, when press drives mould bases upper punch to move to 100 ° from 0 ° of startup, upper punch enters die (die is arranged in die float plate) 8mm left and right to product precompressed, in the time of compacting current location, drive die descending by press, drive die float plate 2 to make DL synchronization by precompressed frictional force.
Under the impact of precompressed frictional force, die float plate 2 DL synchronizations, to wedge adjusting rod mechanism 6, act on sliding bar 711 owing to adjusting screw rod 61, cause die float plate 2 no longer descending, and in product, step forms for the first time and pushes up and press.
Because precompressed powder exists certain frictional force between die internal chamber wall and powder when compressed, powder press power in the time of moulding of compression successively decreases from bottom to top, and mould bases upper punch (or cry " patrix ") comes downwards to 160 ° and makes the interior upper and lower even density of step of product.
When mould bases upper punch continues descending 180 °, this vertical type bidirectional press arranges top pressure makes the outer step of product reach equally upper and lower even density.
The beginning demoulding after formed product finishes, mould bases upper punch is upwards moved, it is descending that mould bases drives lower cavity die to continue at press, the roller 79 that die drives adjustment screw rod 61 to insert wedge sliding mechanism 7 drives guide rail 75 to axially move, form demoulding (interior step) for the first time, now press drives mould bases to continue to go downwards to and sets demoulding position, make product steadily from die, completely depart from and form the demoulding for the second time, the two-way mo(u)ldenpress of the complete vertical type of the demoulding drives mould bases to be back to starting point, and die float plate 2 is returned to charging position under the active force that supports cylinder 5.
