Description

A kind of injection machine heating and cooling system for plastic grain
Technical field
The utility model relates to a kind of plastic grain injection molding apparatus field, particularly relates to a kind of injection machine heating and cooling system for plastic grain.
Background technology
Injection machine the thermoplastic of melting or thermosetting plastics is utilized mould for plastics to make the main former of the plastic products of various shape, is the process equipment that in plastic processing industry, use amount is maximum.Carry out plastic thermoforming add man-hour at use injection machine, due to equipment composition structure, equipment heat temperature raising and to cool all very slow, occupies the time longer in process, significantly limit the production efficiency of injection machine thermo forming.The slow process that simultaneously have impact on thermoforming plastic of heating cooling procedure, when processing link molten plastic mobility is poor, require that rapid conditioning equipment heats up, the heating rate of general device does not catch up with the demand of melt flows to temperature, this problem directly affects the quality of moulded products, reduces the qualification rate of product.
Summary of the invention
According to above technical problem, the utility model provides a kind of injection machine heating and cooling system for plastic grain, comprise thin-walled barrel, feeding spiro rod, injection port mould, heat block, injection mold, sprue gate, outer barrel, it is characterized in that: also comprise heating packing ring, mozzle, diaphragm valve, louvre, be feeding spiro rod in described thin-walled barrel, described feeding spiro rod is singe screw, described thin-walled barrel front end is injection port mould, affiliated thin-walled barrel outer ring is provided with heat block, described heat block is wound with mozzle, described mozzle end is provided with diaphragm valve, outside described heat block, outer barrel is installed, described outer barrel has louvre, described injection port mould front end is sprue gate, described sprue gate connects injection mold, described injection mold outer ring is provided with heating packing ring.
Described heat block has N number of, N >=2.
Described mozzle has N number of, N >=2.
The beneficial effects of the utility model are: the utility model, in molten plastic injection molding process, ensure that system temperature is controlled, and cooling, intensification fast, ensure that production efficiency of equipment.Heat block provided by the utility model is provided with cooling mozzle, and each heat block cooling loop is independent, ensure that the flexibility of each heat block temperature distribution of processing link.Injection mold provided by the utility model is provided with heating packing ring, can preheat injection mold in the processing starting stage, initial manufacture part is made to be unlikely to when flowing forming to cause improved plastics structural shape to be scrapped because cold-setting crossed by mould, reduce raw material loss, improve formed product qualification rate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cross-sectional view of the utility model barrel.
In figure, 1-thin-walled barrel, 2-feeding spiro rod, 3-injection port mould, 4-heat block, 5-injection mold, 6-sprue gate, the outer barrel of 7-, 8-heat packing ring, 9-mozzle, 10-diaphragm valve, 11-louvre.
Detailed description of the invention
Shown in composition graphs 1, the utility model is further described:
Embodiment 1
The utility model comprises thin-walled barrel 1, feeding spiro rod 2, injection port mould 3, heat block 4, injection mold 5, sprue gate 6, outer barrel 7, heating packing ring 8, mozzle 9, diaphragm valve 10, louvre 11, be feeding spiro rod 2 in described thin-walled barrel 1, described feeding spiro rod 2 is singe screw, described thin-walled barrel 1 front end is injection port mould 3, affiliated thin-walled barrel 1 outer ring is provided with heat block 4, described heat block 4 is wound with mozzle 9, described mozzle 9 end is provided with diaphragm valve 10, outside described heat block 4, outer barrel 7 is installed, described outer barrel 7 has louvre 11, described injection port mould 3 front end is sprue gate 6, described sprue gate 6 connects injection mold 5, described injection mold 5 outer ring is provided with heating packing ring 8.
Embodiment 2
During use, first set each heat block 4 temperature, heat block 4 heats up separately, thin-walled barrel 1 conducts heat, heat packing ring 8 to heat up and carry out preheating to injection mold 5 simultaneously, start injection machine, in thin-walled barrel 1, feeding spiro rod 2 carries processing pellet, in thin-walled barrel 1, pellet penetrates through injection port mould 3, injection mold 5 is entered by sprue gate 6 injection, in injection mold 8 chamber of heating packing ring 8 preheating, fused materials flows rapidly and fills in full injection mold 5 chamber, if material melts flowing is too fast or excessively slow, regulate corresponding heat block 4 temperature, to reduce thin-walled barrel 1 internal temperature, corresponding diaphragm valve 10 can be opened, cooling liquid flows through the mozzle 9 be wrapped on heat block 4 takes away partial heat, when heat block 4 temperature is down to preset temperature, close diaphragm valve 10, outer barrel 7 has louvre 11, contribute to heat block 4 and thin-walled barrel 1 dispels the heat, thin-walled barrel 1 internal heat is avoided to assemble, affect plastics melt-processed.
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.
