When 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 limited 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 finish the demoulding and adjust screw rod 61, sliding bar 711 relies on spring 712 expansion force returns after finishing, the recessed float plate 2 of touching supports before and after symmetrical after the demoulding is finished and returns desired location before the compacting under cylinder 5 active forces, prepares next working procedure.
The operation principle explanation of this moulding press.Take compacting EFD series of products as example, fixing of the forming frame is on press, start press after adjusting work loading height and formed product size, two movable parts were made up and down symmetric motion (base 13 about press drove mould bases, beam slab 1 is fixing in fixing, upper die plate 8, moulding platen 64, bearing plate 14 and core bar 9 are movable part up and down, the die float plate also can be up and down along slide post 15, wherein, upper driver part drives upper die plate 8 motions by upper connecting base 81, lower driver part drives bearing plate 14 motions by lower connecting base 140), 360 ° is one-period, when press drive mould bases upper punch moves to 100 ° from 0 ° of startup, upper punch enters about die (die is arranged on the die float plate) 8mm the product precompressed, when the compacting current location, it is descending to drive die by press, drives die float plate 2 by precompressed frictional force and makes DL synchronization.
Under the impact of precompressed frictional force, die float plate 2 DL synchronizations act on the sliding bar 711 owing to adjust screw rod 61 to wedge adjusting rod mechanism 6, cause die float plate 2 no longer descending, and step formation is pressed on the top for the first time in the product.
Because there is certain frictional force in the precompressed powder between die internal chamber wall and the powder when compressed, the powder of compression press power when moulding successively decreases from bottom to top, and mould bases upper punch (or cry " patrix ") comes downwards to 160 ° and makes in the product even density about the step.
When the mould bases upper punch continued descending 180 °, this vertical type bidirectional press arranges the top pressure made the outer step of product reach equally up and down even density.
After finishing, formed product begins the demoulding, the mould bases upper punch is operation upwards, mould bases drives lower cavity die at press and continues descending, die drives the roller 79 drive guide rails 75 of adjusting screw rod 61 insertion wedge sliding mechanisms 7 and axially moves, form for the first time demoulding (interior step), press drive this moment mould bases continues to go downwards to setting demoulding position, product is steadily broken away from from die fully form for the second time demoulding, the two-way mo(u)ldenpress of the complete vertical type of the demoulding drives mould bases and is back to starting point, and die float plate 2 is returned charging position under the active force that supports cylinder 5.
