The movable top pin type vented mould preferably overlapping with polyurethane rubber, also be provided with liftout plate 6(Figure 11, 12) described liftout plate 6 is closely arranged at the top of described backhaul plate 5, the described described backhaul gas circuit 53 that ejects version 6 relatively described backhaul plates 5 is provided with at least one and ejects gas circuit 61, the described gas circuit 61 that ejects is communicated with described sleeve port 51 one end near liftout plate 6, described backhaul plate 5 is provided with cylinder ejector pore 56, one end of described cylinder ejector pore 56 connects air feeder, the other end of described cylinder ejector pore 57 is breach, described breach ejects gas circuit 61 described in being communicated with during with described backhaul plate 5 close installation at described liftout plate 6.Increase liftout plate 6, can to ejecting of movable thimble 3, control by the mode of blowing, greatly reduce the requirement of this mould to machining accuracy.
Described liftout plate 6 is also provided with interior connection counterbore 62 and is connected counterbore 63 with core rod; When described liftout plate 6 and described backhaul plate 5 close installation, described interior connection counterbore 62 is connected with the described interior via hole 55 that is connected, described core rod connection counterbore 63 is connected via hole 56 with described core rod and is connected, for the fixedly movable top pin type vented mould with polyurethane rubber cover of the present embodiment is installed.
Described clear powder plate 4 is also provided with pressure-vaccum pore 42 and dust-proof seal ring 43, and one end of described pressure-vaccum pore 42 connects air feeder and lift pump, described in the other end of described pressure-vaccum pore 42 is communicated with, blows powder passage 41.When matched moulds, pressure-vaccum pore 42 is air-breathing by lift pump, forms negative pressure blowing powder air intake passage 41, make air in die cavity by steam vent 2, blow powder air intake passage 41 and pressure-vaccum pore 42 is drained rapidly; When the demoulding, pressure-vaccum pore 42, by the air blowing of air feeder, blows out the ceramic powder that enters into steam vent 2 from exhaust clearance 12, has avoided Ceramic Dust to be deposited in steam vent 2 and has caused stopping up steam vent 2; Dust-proof seal ring 43 is set can increase the air-tightness of clear powder plate 4 further, makes the through hole that air can not run through by movable thimble 3 enter backhaul plate 5.
Preferably, the lower surface of described core rod body 1 is provided with polyurethane rubber layer 35, adopts polyurethane rubber layer 35 can avoid when matched moulds, and core rod body 1 is stained with ceramic powder and causes scrapping of whole ceramic batch.
During installation, liftout plate 6, backhaul plate 5, clear powder plate 4 and described core rod body 1 are arranged in order from top to bottom, and with screw, by interior connection via hole 55, are connected via hole 56 with core rod it is stepped up to installation.The piston head 31 of described movable thimble 3 is nested in described sleeve port 51, and movable thimble 3 runs through described backhaul plate 5, described clear powder plate 4 and described core rod body 1.Matched moulds is beaten before brick, and thimble head 34 is retracted into the top of tailstock barrel 11, and is a plane with suppressing contact site 14 balances; During matched moulds (Fig. 2), pressure-vaccum pore 42 is by air-breathing, blowing powder air intake passage 41 formation negative pressure, make air in die cavity as described in arrow, through thimble head 34 and the exhaust space 12 of the inside formation of tailstock barrel 11, flow out, and from clear powder plate 4 blow powder air intake passage 41 and pressure-vaccum pore 42 is drained rapidly, guarantee that mould assembling action completes fast smoothly.During die sinking, air feeder is blown to cylinder ejector pore 57, and gas leads to described sleeve port 51 near one end of liftout plate 6 through ejecting gas circuit 61, and makes the piston head of movable thimble 3 movable downwards, thimble head 34(Fig. 3) stretch out tailstock barrel 11, ceramic powder is subject to the effect of gravity and drops out; For fear of when movable thimble 3 ejects, the wearing and tearing that bump and cause with tailstock barrel 11 due to the swing of movable thimble 3, the end of movable thimble 3 is provided with polyurethane rubber cover 38 life-span of movable thimble 3 and tailstock barrel 11 is lengthened; In order to clean out more up hill and dale the powder in exhaust clearance 12, air feeder is blown to pressure-vaccum pore 42, and gas drives the powder remaining in exhaust clearance 12 to discharge by exhaust clearance 12; Subsequently, air feeder is blown to return hydraulic cylinder pore 52, gas leads to sleeve port 51 near one end of clear powder plate 4 through backhaul gas circuit 53, because described backhaul gas circuit 53, described piston head 31 form an airtight space with described clear powder plate 4, so that the piston head of movable thimble 3 31 is upwards movable, thimble head 34 is retracted in tailstock barrel 11, and with compacting contact site 14 balances be a plane, just complete backhaul action, wait for next mould assembling action.
The present invention, the problem that gas when not only having solved ceramic stock mould matched moulds and beating brick is discharged, and also has following beneficial effect: 1. owing to having adopted 3 pairs of steam vents 2 of movable thimble to stretch out and the action of retracting, add the air blowing of gas hole 42, the powder that makes to remain in exhaust clearance 12 can be discharged mould up hill and dale, has avoided the accumulation of ceramic powder and has caused the obstruction of steam vent 2; 2. the end of movable thimble 3 has been provided with polyurethane rubber cover 38, while having avoided movable thimble 3 to eject and tailstock barrel 11 bump and cause both sides' wearing and tearing, but also avoided ceramic powder to stick in thimble head 34 places; 3. during due to matched moulds, adopted pressure-vaccum pore 42 to carry out air-breathing, formed negative pressure blowing powder air intake passage 41, made air in die cavity as described in arrow, more promptly drained; 4. the air blowing of gas hole 42, the powder that makes to remain in exhaust clearance 12 can be discharged mould up hill and dale, has avoided the accumulation of ceramic powder and has caused the obstruction of steam vent 2.The new whole actions of this practicality all can operate automatically, have realized automated production, have greatly reduced artificial operation, have reduced production cost, and the work that need not shut down because of the powder in cleaning steam vent, have greatly improved production efficiency.
Finally should be noted that; above embodiment is only for illustrating technical scheme of the present invention but not limiting the scope of the invention; although the present invention is explained in detail with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement technical scheme of the present invention, and not depart from essence and the scope of technical solution of the present invention.
