Background technology
Existing plastic-injection moulding machine is made up of electric control system, plasticizing injecting systems, matched moulds system, hydraulic system, heating and cooling system, frame etc.This full-automatic horizontal injection machine automaticity height by computer control, production efficiency height, the good product quality of producing.But this injection machine does not have liquid quantitatively injection device, liquid gas can not be dispersed in and form micropore in the plastics, can't produce the goods of porous structural material, makes the product function of production more single.
Summary of the invention
The purpose of this utility model is to provide a kind of little foaming two-shipper tube injector, can in the macromolecule melting charge, quantitatively inject liquid gas, and liquid gas can be dispersed in the macromolecule melting charge, the porous structural material goods are produced in the growth of control bubble.
The purpose of this utility model is achieved in that a kind of little foaming two-shipper tube injector, be included in and cooperate the screw rod that is installed with in the machine barrel by the melten gel fluid motor-driven, little foaming two-shipper tube injector is made of plasticizing extrusion device and plasticizing injecting device, the plasticizing extrusion device is interior cooperation of extruder barrel with loading hopper and discharging opening the extrusion screw rod that is driven by the melten gel hydraulic motor to be installed, the discharging opening of extruder barrel is connecting the charging aperture of the injection cylinder of plasticizing injecting device by tube connector, on the through hole of extruder barrel homogenizing zone barrel, connecting liquid gas injection device by tube connector, the front end of injection cylinder is installed with injection-moulding nozzle, cooperates the injection screw that is driven by the melten gel hydraulic motor is installed in injection cylinder.
During the utility model work, with raw material, nucleator masterbatch, processing aid adds in the loading hopper of extruder barrel, material is heated plasticizing after entering machine barrel, the liquid gas injection device that is installed on the extruder barrel injects liquid gas by equal and quantitative ground in the fused materials of tube connector in extruder barrel, the extrusion screw rod of rotation cuts into tiny drop with liquid gas, it is dispersed in the macromolecule melting charge, the macromolecule melting charge of mixing tube connector by the extruder barrel discharging opening under the promotion of extrusion screw rod enters injection cylinder continuation plasticizing, under the injection screw effect, control the growth of macromolecule melting charge abscess, and pass through the goods of the injection-moulding nozzle injection moulding porous structural material of injection cylinder front end installation.The utility model injects liquid gas owing to quantitative in the macromolecule melting charge, and liquid gas is dispersed in the macromolecule melting charge, the growth of control bubble.The goods of the porous structural material that the utility model is produced, the extremely small densification of its abscess, bulb diameter is the 0.1-10 micron, function with shock resistance, endurance, heat insulation, sound insulation and absorbing, littler than original defective or micro-crack in the high polymer, can make the microcrack crest truncation in the high polymer.Therefore improve the mechanical property of high polymer, improved functions such as shock resistance, endurance, heat insulation, sound insulation and absorbing.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a cross-sectional view of the present utility model.
The specific embodiment
A kind of little foaming two-shipper tube injector, as shown in drawings, be included in and cooperate the screw rod that is installed with in the machine barrel by the melten gel fluid motor-driven, little foaming two-shipper tube injector is made of plasticizing extrusion device and plasticizing injecting device, the plasticizing extrusion device is 3 interior cooperations of extruder barrel with loading hopper 2 and discharging opening the extrusion screw rod 4 that is driven by melten gel hydraulic motor 1 to be installed, the discharging opening of extruder barrel 3 is connecting the charging aperture of the injection cylinder 6 of plasticizing injecting device by tube connector 9, on the through hole of extruder barrel 3 homogenizing zone barrels, connecting liquid gas injection device 11 by tube connector 10, the front end of injection cylinder 6 is installed with injection-moulding nozzle 8, cooperates the injection screw 7 that is driven by melten gel hydraulic motor 5 is installed in injection cylinder 6.The cone centre of injection screw 7 heads is corresponding with the conical inboard wall of injection-moulding nozzle 8.The screw channel of extrusion screw rod 4 is dark for equidistantly not waiting, and its pitch equates that major diameter of thread equates that the screw rod pilum is a batter post, and screw rod pilum head diameter is greater than the diameter of its afterbody.Extruder barrel 3 and the space that extrusion screw rod 4 constitutes are reduced from the afterbody to the head gradually, play the effect of bubble growth in the control macromolecule melting charge.The screw channel of injection screw 7 is not equidistant deeply for waiting, and the pitch of injection screw 7 increases from the afterbody to the head successively, plays the effect of bubble growth in the control macromolecule melting charge.The computing formula of pitch is as follows: S
n=S
1+ S
1Y
(n-1), wherein: S
1Be first pitch, S
nBe n pitch, Y is the pitch spreading coefficient.The macromolecule melting charge is squeezed into injection cylinder 6 and is continued plasticizing, bubble has certain growing space simultaneously, make bubble growth, and be controlled, after finishing plastics capacity, plasticizing extrusion device and plasticizing injecting device stop plasticizing, and injection screw 7 begins to advance injection, and the material that plasticizing is good injects mould molding.When pressurize, next plasticizing is extruded and is plastified injection cycle and begins.The diameter of injection screw 7 is more than or equal to the diameter of extrusion screw rod 4; The draw ratio of injection screw 7 is less than or equal to the draw ratio of extrusion screw rod 4.
