Specific implementation mode
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
- Fig. 3 is please referred to Fig.1, Fig. 1 is a kind of specific implementation mode of automatic folding type nozzle provided by the utility model
Structural schematic diagram；Fig. 2 is the partial enlarged view of the ejection end of automatic folding type nozzle shown in Fig. 1；Fig. 3 is to be opened automatically shown in Fig. 1
The end view of ejection end in box-like nozzle.
In a specific embodiment, automatic folding type nozzle provided by the utility model includes being connected to material access
Material portion 1 and the ejection section 2 that is connected to the material portion 1, the bore of the ejection section 2 be less than the bore in the material portion 1；
Wherein, the ejection section 2 includes cylindrical body part 21 and is installed on the first opening-closing plate of the ejection end of the cylindrical body part 21
22 and second opening-closing plate 23, first opening-closing plate 22 cylindrical body part 21 is articulated with by the first articulated shaft 24 and can
It is rotated relative to the cylindrical body part 21 around first articulated shaft 24, second opening-closing plate 23 passes through the second articulated shaft 25
It is articulated with the cylindrical body part 21 and can be rotated relative to the cylindrical body part 21 around second articulated shaft 25.
Between installation in order to provide return member, which further includes the first mounting bracket 3 and the second mounting bracket 4, and described
One mounting bracket 3 and second mounting bracket 4 are overhanging both with respect to the ejection end, and first mounting bracket 3 is opened with described first
First spring 5 is installed between plywood 22, second spring is installed between second mounting bracket 4 and second opening-closing plate 23
6；When in non-ejection state, the first spring 5 and second spring 6 are in compression or natural length, it is thus evident that when nozzle is horizontal
When structure, material spray direction is horizontal direction, and two springs are under natural length at this time, and nozzle is if vertical structure, especially
It is injection direction straight down when, two springs need to be in certain compressive state, with restoring force can balance opening-closing plate from
Body gravity avoids the unnormal unlocking of opening-closing plate.
When material pressure in the cylindrical body part 21 reaches Opening pressure threshold value, first spring 5 and described the
Two springs 6 are in compressive state, and the separation of two opening-closing plates is to open the ejection end；Material pressure in the cylindrical body part 21
When power is less than the Opening pressure threshold value, two opening-closing plates close in elastic recovery power drive ShiShimonoseki of respective spring to close the spray
Penetrate end.
Above-mentioned two spring can be linear springs, since opening-closing plate is at an angle of setting after unlatching with ejection end, if bullet
Spring is smaller perpendicular to the opening-closing plate torque that then the restoring force point of application generates, therefore, in order to improve the useful work ratio of restoring force, bullet
Certain angle is preferably provided between spring and corresponding opening-closing plate.Specifically, the plate face of the first spring 5 and first opening-closing plate 22
Between angle be 45 ° -60 °, the angle between second spring 6 and the plate face of second opening-closing plate 23 is 45 ° -60 °.
Further, in order to avoid the setting of mounting bracket causes to interfere to material injection, first mounting bracket 3 is L-type
Holder, and the distance between the horizontal edge of the L-type support and the plate face of first opening-closing plate 22 are less than the ejection end and mold
The distance between feed inlet；Second mounting bracket 4 is L-type support, and the horizontal edge of the L-type support and second opening-closing plate 23
The distance between plate face be less than the distance between the ejection end and die feeding mouth；Meanwhile the ejection end is rectangular opens
Mouthful, and first opening-closing plate 22 and second opening-closing plate 23 are rectangular slab, the long side of the rectangular slab and the tubular
Main part 21 is rotatably connected, the broadside of the rectangular slab be greater than or equal between ejection end and the die feeding mouth away from
From.In this way, after opening-closing plate is opened, material actual ejection mouth is the outer end of two opening-closing plates, which ensures
Material spray performance.
During the work time, under original state under the promotion of the first spring 5 and second spring 6,22 He of the first opening-closing plate
Second opening-closing plate 23 is in closed state, then the ejection end of nozzle is closed；In material course of injection, since material itself is deposited
In pressure, the elastic-restoring force of corresponding lateral spring, 22 He of the first opening-closing plate can be broken through when which reaches Opening pressure threshold value
Second opening-closing plate 23 is detached under material momentum effect to open ejection end, and the ejection end of nozzle is opened to realize the normal of material
Injection；After the completion of material injection, the material remained in material access and nozzle does not have pressure, that is, is used for breaking through two springs
The material pressure of the elastic-restoring force of generation disappears, and the first opening-closing plate 22 and the second opening-closing plate 23 are returned in the elasticity of respective lateral spring
It is closed under the collective effect of multiple power, and the ejection end of valve nozzles so that remaining material can not mass flowing nozzle.
In this way, the nozzle by way of being closed automatically, avoids the raw material of molten state from nozzle after the completion of material spray
Outflow, and then avoid raw material and continue to outflow after work, it ensure that the surface smoothness and exterior quality of shaped article,
Reduce defect rate.
