Similar to the syringe having an injection, it is made by the thrust of screw rod, and the plastic injection of the molten condition plastified is entered Guan Bi
In good die cavity, after cured sizing, obtain the technical process of goods.
Injection moulding be one circulation process, each cycle specifically include that quantifying feed, fusion plastification, pressure injection,
Mold filling cools down, opens mould pickup.Take out after plastic mold closing the most again, carry out next circulation.
Injection molding basic demand is plasticizing, injection and molding.Before plasticizing realizes and ensures shaped article quality
Carrying, and be the requirement meeting molding, injection must assure that enough pressure and speed.Simultaneously as injection pressure is the highest, phase
The highest pressure should be produced in ground, it is therefore necessary to have sufficiently large mold clamping force in die cavity.
Current nozzle is all formed in one, and generally uses with mould collocation, but different volumes, thickness, material, shape
The most preferably amount of penetrating needed for plastics is the most different, in some cases mould or product may mould volume big but needed for the amount of penetrating little,
Or need more small-bore nozzle just can obtain higher-quality product, now standard specifications possibly cannot meeting meets demand,
And in the case of existing nozzle, change nozzle or mould, waste time and energy and increase cost, therefore needing a kind of energy of searching badly convenient
Change small-bore nozzle plastic cement injection device.

Side.
The present invention at least includes following beneficial effect:
1, in plastic cement injection device, nozzle is excessive, then actual internal area is big, and the compressive load per unit area of plastics progressive die is low, is formed
The situation that power of penetrating is little, non-Newtonian plastics often can not make viscosity degradation cause mold filling to be stranded because there is no big shear heat
Difficulty, the plastic cement injection device of the present invention for different volumes, thickness, material, shape plastics needed for optimal injection amount and institute
Need to penetrate the situation that power is different, be provided with nozzle regulation device below barrel, the setting of nozzle regulation device makes different bore
The selection of nozzle more flexible.Wherein, change electric magnet polarity, electric magnet can adsorb under electromagnetic action with its polarity phase
On the first anti-permanent magnet, thus it is fixed on original nozzle one end, reduces the injection bore of nozzle, need to regain electric magnet,
When recovering the injection bore of original nozzle, again changing the polarity of electric magnet, the setting of the second permanent magnet makes and its polarity phase
Anti-electric magnet can be sucked back on the second permanent magnet, simple and fast, thus realizes basis in the case of not removing original nozzle
Need to select flexibly the purpose of heavy caliber and more small-bore nozzle, better meet the needs of different plastic cement products, suitable
Injection amount decreases plastic cement products and the possibility of overlap flash occurs, reduces defect rate, thus obtains higher-quality product,
Time saving and energy saving and reduce cost, convenient and swift.
2, in the present invention, the upper opening of feed hopper feeds horizontal by 30 ° of angles, the side higher from feed hopper, from
The side relatively low with feed hopper is positioned at the first charging aperture discharging of the same side, it is ensured that when plastic rubber material stops longer in feeding-passage
Between, obtain more fully, more accurate screening and filtering.The effect once filtered the plastic rubber material entered is played in the setting of screen tray, existing
Often being mixed with impurity and reworked material, wherein, reworked material low in glossiness in some plastic rubber material raw materials, particle surface is dull, size
Uneven, often contain impurity, physical and mechanical properties is the poorest and virgin material, if entering barrel together with virgin material, not only affects plastic cement
The performance of product, it is also possible to work in-process thermal stress-cracking occurs or produces needle-like silvery white such as on plastic surface along stream direction
The filamentary silver stricture of vagina that frost is general, reduces production efficiency, and the most dismountable screen tray can screen out the break flour in raw material, reduces reworked material
Consumption, it is ensured that the quality of products material, dismountable structure is convenient takes off replacing at any time.First charging aperture is positioned at screen tray and screen cloth
Between, and screening enters barrel, i.e. particle diameter from the plastic rubber material that the first charging aperture goes out and is positioned at the grid of screen tray Mesh Diameter and screen cloth
Plastic rubber material between diameter enters barrel, and particle size range is less, and size is uniform, decreases plastic cement products and produces the possibility of filamentary silver stricture of vagina
Property.The setting of stirring paddle not only makes plastic rubber material mix, and contributes to particle diameter between screen tray Mesh Diameter and the Mesh Diameter of screen cloth
Plastic rubber material enter barrel, and certain effect that raw material is dried can be played, reduce further plastic cement products filamentary silver
The probability that stricture of vagina and bubble produce, is conducive to obtaining higher-quality product.
3, in the present invention, the heater strip of major arc shape has a bigger temperature radiation scope, equidistant of the three pairs of heaters
Every being distributed in the front portion within barrel, middle part and rear portion, it is ensured that can evenly the material in barrel be entered in whole barrel
Row heats, and the heating-up temperature of every part is monitored in multiple temperature sensors at any time, and when temperature exceedes the upper limit, single-chip microcomputer makes control
Device controls to switch closes, and stops heating, and when temperature is less than the upper limit, single-chip microcomputer makes controller control switch open, and restarts
Heating, same temperature ranges stated preset by each heater, it is ensured that the temperature in whole barrel is maintained at identical temperature range, energy
The plastic rubber material that makes evenly adds heat fusing, and will not because of the performance affecting plastic cement products too high or too low for temperature, decrease because of
Temperature is too high makes product overlap or the too low probability making product embrittlement or lapping defect occur of temperature occur.
4, the glass fiber material of dopen Nano Graphene has good heat conductivility, makes the heating of heater strip have more
Big temperature radiation scope, covers and makes heating the most further evenly in barrel, do not have local temperature too high or too low,
Adulterate in convexity layer the higher nano-graphene of mass fraction, had both made to have near the top layer of heater preferably to make heat
Amount homogeneous radiation function, the circular protrusions in convexity layer can play certain self-cleaning effect simultaneously, be difficult to be infected with plastic rubber material or
Other impurity, Nano-meter SiO_22The thermal insulation layer spraying of composite ceramic material, near the surface of barrel outer wall, plays good insulation
Effect, makes heat to scatter and disappear to outside easily.
Part is embodied by the further advantage of the present invention, target and feature by description below, and part also will be by this
Invention research and practice and be understood by the person skilled in the art.
