Abstract
A hanging-platform gap-avoiding injection nozzle assembly comprises an injection nozzle and a shunting plate, and the injection nozzle is fixedly disposed on the shunting plate via multiple screws and positioning pins; the injection nozzle comprises an injection nozzle hanging platform and an injection nozzle head; the connection surface between the shunting plate and the injection nozzle is provided with a copper stripe groove in which a heating copper strip is arranged; the copper stripe groove is O-shaped and is arranged on the shunting plate; the injection nozzle is arranged at the inner side of the copper stripe groove; and a gap is arranged between the injection nozzle hanging platform and the copper strip groove in the radial direction. The hanging-platform gap-avoiding injection nozzle assembly is simple in structure and convenient to assemble, the injection nozzle does not press the heating copper strip in the copper strip groove, so that no gas is generated between the shunting plat and the injection nozzle because of expansion of the heating copper strip when the injection nozzle assembly is running, and the injection nozzle assembly helps to effectively avoid glue leakage of the system and prolong the service life of the system.
Description
Technical field
The present invention relates to a kind of hanging platform empty avoiding injection nozzle assembly, particularly a kind of injection nozzle assembly that changes injection nozzle hanging platform portion shape glue-leakage-resistant.
Background technology
Flow distribution plate is the central module of TOP-TIP, and the plastic solution that it carrys out the transmission of sprue nozzle is distributed to each injection nozzle through fluid passage, by injection nozzle, plastic solution is injected in the die cavity of mould.Conventional injection nozzle assembly, as described in Figure 1, comprises flow distribution plate 1 and injection nozzle 2 at present, and described injection nozzle 2 is directly fixed on flow distribution plate 1 by several screws 3 and alignment pin 4; Described injection nozzle 2 comprises injection nozzle hanging platform portion 5 and injection nozzle head 6, on the surface that described flow distribution plate 1 is connected with injection nozzle 2, offer copper bar groove 7, in described copper bar groove 7, be provided with heating copper bar, because injection nozzle hanging platform portion 5 is cylindrical, therefore injection nozzle hanging platform portion 5 has two small semicircles to be pressed on the heating copper bar of flow distribution plate 1, because the coefficient of expansion of copper is larger than steel, during heating, copper bar can exceed the surface of flow distribution plate 1 after expanding, injection nozzle 2 is subject to copper bar extruding, can cause forming gap between flow distribution plate 1 and injection nozzle 2, cause system to leak glue.
Summary of the invention
Technical problem for above-mentioned existence, the object of the invention is: proposed a kind of injection nozzle assembly that changes injection nozzle hanging platform portion shape glue-leakage-resistant.
Technical solution of the present invention is achieved in that a kind of hanging platform empty avoiding injection nozzle assembly, comprises flow distribution plate and injection nozzle, and described injection nozzle is fixed on flow distribution plate by several screws and alignment pin; Described injection nozzle comprises injection nozzle hanging platform portion and injection nozzle head; On the surface that described flow distribution plate is connected with injection nozzle, offer copper bar groove, in described copper bar groove, be provided with heating copper bar; Described copper bar groove is O shape and is opened in flow distribution plate surface, and described injection nozzle is arranged on the inner side of described copper bar groove; Between described injection nozzle hanging platform portion and copper bar groove, footpath is upwards provided with gap.
Preferably, described injection nozzle hanging platform portion is the truncated disc-shapes in both sides.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of hanging platform empty avoiding injection nozzle assembly of the present invention, comprise flow distribution plate and injection nozzle, described injection nozzle mouth is arranged on the inner side of copper bar groove on flow distribution plate, between injection nozzle hanging platform portion and copper bar groove, footpath is upwards provided with gap, therefore injection nozzle can not be pressed onto the heating copper bar in copper bar groove, during work, with regard to not causing because heating copper bar expands, produces gap between flow distribution plate and injection nozzle; A kind of hanging platform empty avoiding injection nozzle assembly of the present invention, simple in structure, easy for installation, can be effectively anti-locking system leak glue, can extend system service life.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
The structural representation of a kind of injection nozzle assembly that accompanying drawing 1 is prior art;

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Accompanying drawing 3 is a kind of hanging platform empty avoiding injection nozzle assembly of the present invention, comprises flow distribution plate 1 and injection nozzle 2, and described injection nozzle 2 is fixed on flow distribution plate 1 by several screws 3 and alignment pin 4; Described injection nozzle 2 comprises injection nozzle hanging platform portion 5 and injection nozzle head 6; On the surface that described flow distribution plate 1 is connected with injection nozzle 2, offer copper bar groove 7, in described copper bar groove 7, be provided with heating copper bar; Described copper bar groove 7 is O shape and is opened in flow distribution plate 1 surface, and institute's injection nozzle 2 is arranged on the inner side of described copper bar groove; Between described injection nozzle hanging platform portion 5 and copper bar groove 7, footpath is upwards provided with gap; In the present embodiment, described injection nozzle hanging platform portion 5 is the truncated disc-shapes in both sides.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of hanging platform empty avoiding injection nozzle assembly of the present invention, comprise flow distribution plate and injection nozzle, described injection nozzle is arranged on the inner side of copper bar groove on flow distribution plate, between injection nozzle hanging platform portion and copper bar groove, footpath is upwards provided with gap, therefore injection nozzle can not be pressed onto the heating copper bar in copper bar groove, during work, with regard to not causing because heating copper bar expands, produces gap between flow distribution plate and injection nozzle; A kind of hanging platform empty avoiding injection nozzle assembly of the present invention, simple in structure, easy for installation, can be effectively anti-locking system leak glue, can extend system service life.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
