Abstract
The utility model relates to a hanging table clearance injection nozzle component which comprises an injection nozzle and a shunt plate, wherein the injection nozzle is fixed on the shunt plate through multiple screws and positioning pins; the injection nozzle comprises an injection nozzle hanging table part and an injection nozzle head; a copper bar groove is formed in the surface, connected with the injection nozzle, of the shunt plate; a heating copper bar is arranged in the copper bar groove; the copper bar groove is in an O shape and is formed in the surface of the shunt plate; the injection nozzle is arranged on the inner side of the copper bar groove; a gap is formed between the injection nozzle hanging table part and the copper bar groove in the radial direction. According to the scheme, the hanging table clearance injection nozzle component is simple in structure and convenient to mount, and as the injection nozzle does not press the heating copper bar in the copper bar groove, a phenomenon that a gap is formed between the shunt plate and the injection nozzle because the heating copper bar expands is avoided during operation, so that glue leakage in the system can be effectively avoided, and the service life of the system can be prolonged.
Description
Technical field
The utility model 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, when 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.
Utility model content
The utility model object is that a kind of injection nozzle assembly that changes injection nozzle hanging platform portion shape glue-leakage-resistant is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of hanging platform empty avoiding injection nozzle assembly, comprise 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 utility model compared with prior art has following advantages:
A kind of hanging platform empty avoiding injection nozzle assembly of the utility model scheme, 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, just can not cause because heating copper bar expands producing between flow distribution plate and injection nozzle gap when work; A kind of hanging platform empty avoiding injection nozzle assembly of the utility model scheme, 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 solutions of the utility model are described further:
The structural representation of a kind of injection nozzle assembly that accompanying drawing 1 is prior art;
The cutaway view of injection nozzle in a kind of injection nozzle assembly that accompanying drawing 2 is prior art;
Accompanying drawing 3 is the structural representation of a kind of hanging platform empty avoiding injection nozzle assembly of the utility model embodiment;
Wherein: 1, flow distribution plate; 2, injection nozzle; 3, screw; 4 alignment pins; 5, injection nozzle hanging platform portion; 6, injection nozzle head; 7, copper bar groove.
the specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 3 is a kind of hanging platform empty avoiding injection nozzle assembly described in the utility model, 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 utility model compared with prior art has following advantages:
A kind of hanging platform empty avoiding injection nozzle assembly of the utility model scheme, 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, just can not cause because heating copper bar expands producing between flow distribution plate and injection nozzle gap when work; A kind of hanging platform empty avoiding injection nozzle assembly of the utility model scheme, simple in structure, easy for installation, can be effectively anti-locking system leak glue, can extend system service life.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
