Description
Technical field:
The present invention relates to a kind of mechanical means that is applicable to the moulding of complicated shaped blank height quality, specifically a kind of gel injection-moulding shaping machine that is exclusively used in slurry processing in the blank forming technology.
Technical background:
Existing gel casting forming technology is the new technology of the U.S. in 1991 as the invention of Shu Ling laboratory.It is applied to polymer chemistry polymerization technique, colloid chemistry technology in the moulding of fine ceramics, is a kind of forming method of accurate dead size.Its processing step has premixed liquid, ball milling (adding the porcelain powder), slurry, degasification, initiator, stirring, degasification again, adds injection molding, gelation, mould unloading, drying etc.Wherein: preceding three-procedure is the high solid loading pulp preparation.Back five steps operation is the processing of slurry, and they are concerning the quality of molding blank.Pulp preparation is carried out in ball mill, but the processing of slurry does not also have specialized apparatus at present.General way is: at first slurry being poured into the vacuum stirring device, is 10 in vacuum tightness
-1Handled 10-14 minute under the τ condition, add initiator and catalyzer behind the removal bubble; Vacuum-treat is 5 minutes again, and vacuum tightness still is 10
-1τ.With the slurry cast model of handling well.The outstanding shortcoming that present method exists is need vacuumize for twice before and after initiator adds, and complicated operation is consuming time many; Secondly, the slurry of adding initiator must use up in 10 minutes.Otherwise gelation begins, and cast can't be carried out.When casting large was annotated part, the duration of pouring was long, and for preventing gelation, slurry need be cooled to about 5 ℃, and exhaustless slurry also will so be handled just and can preserve, and is higher to the condition that technological process requires; Once more,,, need to use thrust-augmenting nozzle,, also need slurry is moved into pressurized keg, exert pressure with air compressor machine for improving the flow velocity of slurry in thrust-augmenting nozzle for avoiding producing bubble to some bigger notes spares.As seen, inconvenient operation, facility investment is greatly two basic shortcomings of the prior art.
Summary of the invention:
The objective of the invention is to overcome deficiency of the prior art, seek to design a kind of gel injection-moulding shaping machine that slurry is handled that is exclusively used in, degasification in the gel injection, adding initiator, stirring, degasification again, these a series of operations of injection molding are incorporated in the machinery equipment and finish, save unit cooler, air compressor machine pressure exerting device simultaneously, and the slip casting time is unrestricted, and realization reduces cost, easy to operate, energy-conservation, timesaving effect.
The present invention's gel injection-moulding shaping machine is made up of charging bucket, vacuum chamber, vacuum system, screw propulsion and parts such as agitator assembly, buncher and micrometering pump.Charging bucket is funnel-form, and its top is equipped with filter screen and is used for the filtering abrading-ball, and the flow velocity of a ball valve with the control slurry is equipped with in the bottom.The wedged interface of ball valve bottom docks with funnelform vacuum chamber, and forms good sealing.Vacuum chamber top cover central interface bottom is provided with tap hole, having the vacuum suction hole by top one side connects with the vacuum system of being made up of vacuum pump, metrical instrument and two valves and is communicated with, respectively there is a valve vacuum chamber upper and lower part, to guarantee fully to remove air and the sealing in the slurry.Be shaped on screw propulsion and agitator assembly in the bottom of vacuum chamber.The leading portion of assembly partly is a thruster, is used to carry slurry, and slurry is applied certain pressure; Back segment partly is an agitator, the initiator that adds and catalyzer and slurry can be stirred.Isolated during stirring because of slurry and air, so can not sneak into bubble, saved secondary degasification operation.Longer pitch time when twice injection molding, and when in time not closing micrometering pump in advance, the slurry that has mixed initiator and catalyzer can solidify gradually.Rearmounted agitator is easy to disassembly, cleaning; Because of slurry curing only only limits in the agitator, the slurry of waste seldom again.Screw propulsion and agitator assembly one side realize the shaft coupling running with buncher by a main shaft, to supply with screw propulsion and agitator assembly power.The flow of slurry and the size of pressure are by adjusting the control of buncher rotating speed.The agitator sidewall links to each other with micrometering pump by valve, and micrometering pump links to each other with the reinforced cup of initiator and catalyzer again, can carry the liquid of accurate measurement, carries initiator and catalyzer with it, is injected in the slurry in the agitator.Connect thrust-augmenting nozzle by valve behind the agitator, thrust-augmenting nozzle is inserted the slurry outlet place of agitator rear end, slurry flows out can carry out die casting.
Charging bucket is funnel-form, makes of stainless steel; Buncher and screw propulsion and the running of agitator assembly shaft coupling, the leading portion of main shaft is shaped on spiricle, and back segment is shaped on stirrer gear; Slurry flow in screw propulsion and the agitator assembly and pressure size are by adjusting the control of buncher rotating speed.
The present invention's gel injection-moulding shaping machine combines in a machine with multiple working procedure of the prior art, need not twice degasification, refrigerator and air compressor have been saved, the processing of also needn't lowering the temperature of unspent slurry, the speed and the adjustable in pressure of cast, therefore improved pouring speed and quality, have reduce equipment cost, easy to operate, save time, outstanding advantage such as energy-conservation.
Description of drawings:
Fig. 1 is the present invention's structural principle synoptic diagram.
