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 end view of ejection end in automatic folding type nozzle shown in Fig. 1；Fig. 3 is ejection end shown in Fig. 2
End face partial sectional view.
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；It is described
The end of first opening-closing plate 22 towards second opening-closing plate 23 is equipped with the first magnetic sheet 3, and second opening-closing plate 23 is towards institute
The end for stating the first opening-closing plate 22 is equipped with the second magnetic sheet 4, and first magnetic sheet 3 and second magnetic sheet 4 are attracted；Described
First return spring, second opening-closing plate 23 and the tubular are installed between one opening-closing plate 22 and the cylindrical body part 21
Second return spring is installed between main part 21, when first magnetic sheet 3 is in discrete state with second magnetic sheet 4, institute
It states the first return spring and is in compressive state with second return spring；First opening-closing plate 22 is opened and closed with described second
In the closure state, first magnetic sheet 3 and second magnetic sheet 4 are attracting to merge the injection for closing the ejection section 2 to plate 23
End, when first opening-closing plate 22 is in open state with second opening-closing plate 23, first magnetic sheet 3 and second magnetic
Piece 4 is separated and opens the ejection end of the ejection section 2.
It should be understood that the magnetic force size of 3 and second magnetic sheet 4 of above-mentioned first magnetic sheet, the second return spring and second time
The restoring force size of position spring, should all determine, pressure when normally discharging can normally open injection according to the pressure of material
Subject to end.
The problem of tightness is not easy to ensure is opened and closed caused by opening-closing plate in order to avoid magnetic sheet protrudes from, and may be used magnetic
Piece is embedded in the mode in corresponding opening-closing plate, and specifically, the end of first opening-closing plate 22 towards second opening-closing plate 23 is opened
Equipped with the first storage tank, first magnetic sheet 3 is embedded in first storage tank；Second opening-closing plate 23 is towards described first
The end of opening-closing plate 22 offers the second storage tank, and second magnetic sheet 4 is embedded in second storage tank.It is apparent that working as magnetic
When piece thickness is little, the end for being fitted in magnetic sheet is also unlikely to affect greatly adaptation, or can be covered with magnetic sheet
The entire Mosaic face of opening-closing plate edge joint position.
Above-mentioned first opening-closing plate 22 is arc with the piece of second opening-closing plate 23 or is that S types etc. are convenient for the shape being bonded
Formula, it is thus evident that when the arc that the piece end of the first opening-closing plate 22 is evagination, matched, the piece end of the second opening-closing plate 23
It should be the arc of indent.
During the work time, the first magnetic sheet 3 and the second magnetic sheet 4 are in attracting state under original state, then the injection of nozzle
End is closed；In material course of injection, since material itself is there are pressure, which can break through the first magnetic sheet 3 and second
Magnetic force between magnetic sheet 4 and overcome corresponding side return spring spring-return power, the first magnetic sheet 3 and the second magnetic sheet 4 are in material
It is detached under momentum effect, the ejection end of nozzle is opened to realize that the positive production of material is sprayed；After the completion of material injection, object is remained in
Material in material access and nozzle does not have pressure, that is, is used for breaking through two magnetic sheet magnetic forces and the material pressure of spring-return power disappears
Lose, the first opening-closing plate 22 and the second opening-closing plate 23 two magnetic sheets the spring-return power for being attracted magnetic force and two return springs it is common
Effect is lower to be closed, 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.
It should be pointed out that the ordinal numbers such as " first, second " described in text, merely to distinguishing the different knots of same names
Structure does not indicate that certain sequence, more should not be construed as any restriction only for convenience of description.
