The specific embodiment
As shown in Figure 1, a kind of isostatic compaction mould described in the utility model is to be made up of former assembly 1 and formpiston assembly 2.Wherein:
Former assembly 1 comprises die holder 11, die 12, soft die 13 and pressure ring 14.Die holder 11 is to be installed on the portable plate that is driven by the press piston, which is provided with pouring orifice 111 and Qi Nei and is provided with the oil pocket 112 that is communicated with pouring orifice 111.One end face of die 12 on die holder 11, is provided with some intercommunicating pores 121 that are communicated with oil pocket 112 by screw and O RunddichtringO 15 sealing and fixing in the die 12.Soft die 13 is overlying on the other end of die 12, and by pressure ring 14 sealing and fixing.Pressure ring 14 outer rims are provided with rubber seal ring 16.
Formpiston assembly 2 comprises punch holder 21, convex mould base 22, punch 23, soft punch 24 and pan feeding ring 25.Punch mould 24 is fixed on the end face of punch 23.Punch 23 is fixed on the convex mould base 22 by screw.Convex mould base 22 is fixed on the punch holder 21 by screw.Punch holder 21 is installed on the fixed head of press.Be provided with locating shaft 26 between punch 23, convex mould base 22 and punch holder 21 threes.Pan feeding ring 25 is to be movably set on punch 23 and the convex mould base 24, and is installed on by one that its axis along punch 23 and convex mould base 24 of drive mechanism moves around on the punch holder 21.The internal ring wall of pan feeding ring and external annulus are provided with wear ring 257.
Above-mentioned pan feeding ring 25 is provided with feeding mouth 251 and the interface 252 that is connected with vacuum generating device, is provided with the evacuation passageway 254 that is communicated with interface 252 in the pan feeding ring.One end face of pan feeding ring 25 is provided with feedboard 255, offers the pan feeding passage 253 that is communicated with charging aperture 252 in the pan feeding ring of corresponding feedboard 255; Feeding mouth 251 places are connected with a hopper 256.
The driving mechanism of above-mentioned driving pan feeding ring motion is made up of charging ram 31, pusher axle 32 and copper sheathing 33, and charging ram 31 is installed on the punch holder 21 and by the feeding oil cylinder promotion of press; Pusher axle 32 passes punch holder 21, and contact is on the end face of charging ram 31 and pan feeding ring 25 respectively at its two ends, and copper sheathing 33 is sheathed on outside the pusher axle 32.
In addition, between pan feeding ring 25 and punch holder 21, be provided with elastic recovery mechanism.This elastic recovery mechanism is made up of screw 41, spring base 42 and spring 43.Screw 41 passes punch holder 21 and is connected with pan feeding ring 25, and 43 on spring base 42 and spring are set on the screw 41.
The course of work of the present utility model is as follows:
Piston action on the press drives whole former assembly and moves right to an assigned address, this moment former assembly composition surface M and formpiston assembly composition surface N near but do not fit, piston stops action.Subsequently, the feeding oil cylinder drive charging ram of startup press and pusher axle promotion binder hoop move left former assembly composition surface M and formpiston assembly composition surface N are fitted, at this moment, binder ring, soft former and soft formpiston three are enclosed die cavity, and pan feeding passage and evacuation passageway in the binder ring are communicated with this die cavity.And elastic recovery mechanism is in energy accumulating state at this moment.Start the vacuum generating device that is connected with interface then, then powder enters in the die cavity along the pan feeding passage in the hopper, and removes the assorted gas in the powder.After die cavity is full of powder, restarts piston on the press and make it to drive whole former assembly and continue to move right and promote the pan feeding ring and also move right, simultaneously the powder in the die cavity is carried out mechanical pre-compacted with elastic recovery mechanism.When the pan feeding ring retreated to the end face applying of its end face and punch holder, former and formpiston were integrated, and promptly mould is in the matched moulds state.After press produces enough mold clamping forces, feed the hydraulic oil of about 30MPa toward pouring orifice, hydraulic oil enters the oil pocket of die holder and the intercommunicating pore by former acts on the soft die, waits static pressure to suppress to the base substrate in the die cavity.After compacting was finished, the piston on the press drove the former assembly and retreats left, and the base substrate that is compacted comes off automatically; And in former assembly fallback procedures, connect vavuum pump at the pouring orifice place hydraulic oil that enters in the former oil pocket is aspirated, soft die is resetted.So, promptly finishing once the static pressure that waits of daily porcelain dish base substrate suppresses.
