Abstract
The utility model relates to an injection molding part applied to a mold, in particular to a mold hot nozzle. The mold hot nozzle comprises a spraying plastic tube core, wherein one end of the spraying plastic tube core is provided with a feeding mouth, the feeding mouth is in threaded connection with the spraying plastic tube core integrally, a core block is plugged on the feeding mouth, a heat-emitting ring is further sleeved outside the spraying plastic tube core, the feeding mouth is plugged on a module in a matched mode, and a water way communicated with the feeding mouth is arranged in the module. A beryllium copper insert is sleeved outside the feeding mouth in a matched mode, is in plugged connection with a sleeve in a matched mode, is in gap match with a spray head of the feeding mouth and is arranged between the feeding mouth and the module, and a thermal expansion gap is reserved between an outer wall of the feeding mouth at the position of a water way port and the module. The temperature in injection molding is reduced, white light spots produced by overhigh temperature of the product surface in production are avoided, and the pass percent of products is improved greatly.
Description
Technical field
The utility model relates to a kind of articles injection-moulded in the mould of being applied to, and refers in particular to a kind of mold hot nozzle.
Background technology
In the mould of hot flow path upside-down mounting, when using conventional feed nozzle to advance glue at the product back side, product spot can occur at the glue-feeder place, fraction defective is very high, has a strong impact on the outward appearance of product, thereby product is not accepted by the client, and the principal element that causes this reason is in injection moulding process, excess Temperature when feed nozzle advances glue, thus make shaped article after the demoulding, produce the white light spot, affect the outward appearance of product.
The utility model content
The technical problem that one, will solve
The purpose of this utility model is for the existing the problems referred to above of prior art, and it is a kind of simple in structure that the spy provides, the mold hot nozzle that can effectively lower the temperature to feed nozzle.
Two, technical scheme
For solving the problems of the technologies described above, the utility model mold hot nozzle, comprise a plastic-blasting tube core, this plastic-blasting tube core one end is provided with feed nozzle, above-mentioned feed nozzle and above-mentioned plastic-blasting tube core are screwed into one, grafting one pellet on the above-mentioned feed nozzle, above-mentioned plastic-blasting tube core also is socketed a heating circle outward, above-mentioned feed nozzle cooperation is plugged on the module, be provided with the water route that communicates with feed nozzle in this module, wherein, above-mentioned feed nozzle fit on is socketed a beryllium copper mold insert, and this beryllium copper mold insert cooperates grafting with sleeve pipe, the shower nozzle matched in clearance of above-mentioned beryllium copper mold insert and feed nozzle, above-mentioned beryllium copper mold insert is arranged between feed nozzle and the module, is provided with expansion gap between the feed nozzle outer wall at mouth place, above-mentioned water route and the module.
As optimization, above-mentioned beryllium copper mold insert outer wall has seal groove, is provided with sealing ring in the sealing groove, takes away heat by water quench beryllium copper mold insert.
As optimization, above-mentioned sleeve pipe and above-mentioned plastic-blasting tube core matched in clearance.
Three, the beneficial effects of the utility model
Reduced the temperature when injection moulding, avoided that product surface has improved the qualification rate of product greatly because of the white light spot that excess Temperature produces when producing.
Description of drawings
Fig. 1 is the cutaway view of the utility model mold hot nozzle;
Fig. 2 is the A section enlarged drawing of Fig. 1;
Fig. 3 is the explosive view of the utility model mold hot nozzle;
Fig. 4 is the use view of the utility model mold hot nozzle.
Among the figure, 1 is the plastic-blasting tube core, and 2 is feed nozzle, and 3 is pellet, and 4 are the heating circle, and 5 is module, and 6 is the water route, and 7 is the beryllium copper mold insert, and 8 is expansion gap, and 9 is seal groove, and 10 is sealing ring, and 11 is charging aperture.
The specific embodiment
Below in conjunction with accompanying drawing the utility model mold hot nozzle is described further:
Embodiment one: as shown in Figures 1 to 4, the utility model mold hot nozzle, comprise a plastic-blasting tube core 1, these plastic-blasting tube core 1 one ends are provided with feed nozzle 2, above-mentioned feed nozzle 2 is screwed into one with above-mentioned plastic-blasting tube core 1, grafting one pellet 3 on the above-mentioned feed nozzle 2, the above-mentioned plastic-blasting tube core 1 outer heating circle 4 that also is socketed, above-mentioned feed nozzle 2 cooperations are plugged on the module 5, be provided with the water route 6 that communicates with feed nozzle 2 in this module 5, wherein, above-mentioned feed nozzle 2 fit ons are socketed a beryllium copper mold insert 7, and this beryllium copper mold insert 7 cooperates grafting with sleeve pipe, the shower nozzle matched in clearance of above-mentioned beryllium copper mold insert 7 and feed nozzle 2, above-mentioned beryllium copper mold insert 7 is arranged between feed nozzle 2 and the module 5, is provided with expansion gap 8 between feed nozzle 2 outer walls at 6 mouthfuls of places, above-mentioned water route and the module 5.
Above-mentioned beryllium copper mold insert 7 outer walls have seal groove 9, are provided with sealing ring 10 in the sealing groove 9; Above-mentioned sleeve pipe and above-mentioned plastic-blasting tube core 1 matched in clearance.
In use, the mold hot nozzle that assembles is installed on the module 5, makes above-mentioned beryllium copper mold insert 7 middle part correspondences be arranged on water route 6 in the module 5, and be provided with the expansion gap 8 that liquid circulation is circulated between beryllium copper mold insert 7 middle parts and the module 5.When injection moulding, the plastic material of hot melt enters into feed nozzle 2 from the core of plastic-blasting tube core 1, above-mentioned feed nozzle 2 cooperates with beryllium copper mold insert 7 gaps, when plastic material reaches certain amount, the mouth of feed nozzle 2 outwards struts because of the pressure of inside, plastic material just can be extruded from the mouth of feed nozzle 2, passes the charging aperture 11 corresponding with feed nozzle 2 that is arranged on module 5 bottoms, enters in the die cavity.The external diameter of one end of above-mentioned pellet 3 is slightly larger than the diameter of charging aperture 11, and leaves the gap of passing through for plastic raw materials between pellet 3 and the charging aperture 11.
In injection molding process, cooling fluid by water 6 circulations enters in the expansion gap 8, and beryllium copper mold insert 7 is lowered the temperature.In injection moulding process, beryllium copper mold insert 7 can absorb the heats of feed nozzles 2 in a large number, and the cooling fluid that circulates in water route 6 can be taken away a large amount of heats, thereby reaches cooling effect.
Above-mentioned seal groove 9 has two, be separately positioned on top and the below of expansion gap 8, be provided with sealing ring 10 in the seal groove 9, like this, the module 5 of expansion gap 8 tops and below is sealed and matched with beryllium copper mold insert 7, cooling fluid can not leaked in the circulating cooling process.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
