Description
Technical field
The utility model relates to a kind of plastic grain injection molding apparatus field, particularly relates to a kind of injection machine material prepressing device for plastic grain.
Background technology
In plastic grain injection molding process, the reason causing plastic shaping bad may be that material, equipment or operation etc. are many-sided.With regard to equipment, the phenomenon Producing reason such as common profiled member injection deficiency, overflow edge may be that injection machine plasticizing capacity is too small or excessive, and injection pressure is too little or too greatly, and in die cavity, stream is not smooth or uneven etc.Material is filled, in injection moulding process the adjustment of each section of pressure and temperature be injection mo(u)lding whether key.
Summary of the invention
According to above technical problem, the utility model provides a kind of injection machine material prepressing device for plastic grain, comprise hopper, feeding spiro rod, heat block, temperature detector, interior barrel, outer sleeve, it is characterized in that: also comprise pressurization screw rod, wireway, drain tap, it is pressurization screw rod below described hopper, described pressurization screw rod is spiral Collapsible structure, described pressurization screw front end is feeding spiro rod, described pressurization screw rod and feeding spiro rod are for being threaded, the outer ring of described pressurization screw rod and feeding spiro rod is provided with interior barrel, described interior barrel correspondence pressurization screw position is provided with heat block, described interior barrel is provided with wireway above pressurization screw rod, around described heat block, outer sleeve is installed, described outer sleeve is provided with drain tap, described drain tap is connected with wireway, described outer sleeve is provided with temperature detector, described temperature detector is connected with interior barrel.
The beneficial effects of the utility model are: the utility model, in plastic grain process of injection molding, can carry out preheating pressurized treatments to material, improve plastic melting melt flow rate, increase plasticizing capacity, improve injection mo(u)lding efficiency.Extension type pressurization screw rod provided by the utility model is after plastic grain enters screw rod, add hot extrusion, send material to feeding spiro rod, pressure and plasticizing storing capacity in barrel can be improved, the probability that the problem such as lack of fill, indenture, bubble during reduction molten plastic is shaping produces.Drain tap provided by the utility model can the air pressure of internal barrel regulate, and material can be decomposed the void gas produced and discharge, reduce the impact that gas is shaping on molten plastic.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, barrel in 1-hopper, 2-feeding spiro rod, 3-heat block, 4-temperature detector, 5-, 6-outer sleeve, 7-pressurize screw rod, 8-wireway, 9-drain tap.
Detailed description of the invention
Shown in composition graphs 1, the utility model is further described:
Embodiment 1
The utility model is a kind of injection machine material prepressing device for plastic grain, comprise hopper 1, feeding spiro rod 2, heat block 3, temperature detector 4, interior barrel 5, outer sleeve 6, pressurization screw rod 7, wireway 8, drain tap 9, it is pressurization screw rod 7 below described hopper 1, described pressurization screw rod 7 is spiral Collapsible structure, described pressurization screw rod 7 front end is feeding spiro rod 2, described pressurization screw rod 7 and feeding spiro rod 2 are for being threaded, the outer ring of described pressurization screw rod 7 and feeding spiro rod 2 is provided with interior barrel 5, described interior barrel 5 correspondence pressurization screw position is provided with heat block 3, described interior barrel 5 is provided with wireway 8 above pressurization screw rod 7, around described heat block 3, outer sleeve 6 is installed, described outer sleeve 6 is provided with drain tap 9, described drain tap 9 is connected with wireway 8, described outer sleeve 6 is provided with temperature detector 4, described temperature detector 4 is connected with interior barrel 5.
Embodiment 2
During use, opening device, pour plastic processing raw material into hopper 1, pressurization screw rod 7 helical rotation starts to transmit material, the heating-up temperature of corresponding heat block 3 is set as desired value, make the material of this section of conveying through being heated to glutinous bullet state, pressurization screw rod rotating shrinking, material is extruded and transfers to pressurization screw rod 7 front end, in hopper 1, pressurization screw rod 7 second half section filled by material, pressurization screw rod 7 front end material is through bolt rotary, be transported and transfer to feeding spiro rod 2, temperature indicator 4 records the real time temperature in processing transmitting procedure, if pressure is larger in interior barrel 5, the drain tap 9 on sleeve 6 mounted externally can be opened, gas in interior barrel 5 is discharged from drain tap 9 by wireway 8, treat that pressure recover is normal, close drain tap 9.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
