Impurity is removed by the filtering of filter screen 310 when at strainer 310, the modeling of filtering is passed through in the first runner 110 and the second runner 120
Glue crosses into sprue 130, finally injects mold cavity from spray-hole 103.When filter screen 310 uses a period of time
Afterwards, locking member 400 is opened, filter screen structure is rotated in annular groove 140, the filter screen 310 rotates, will not
The position that the first runner 110 and the second runner 120 are gone to using the filter screen 310 of part is reused locking member 400 and incited somebody to action
Filter structure locking, so that the replacement of filter screen 310 becomes convenient, fast, and easy to operate.
In order to realize that the plastic cement of 310 pairs of filter screen meltings is filtered, in one embodiment, the filter screen
310 be metal-rubber filter screen 310, and the metal-rubber filter screen 310 is made of stainless steel wire, does not contain any natural rubber
Glue, but there is capillary open structure to extract out from hothouse so as to realize filter effect, and its high-low temperature resistant
Gas also has certain temperature, and 310 high temperature resistant of metal-rubber filter screen is not easy to improve because of high temperature damage and aging
Service life.
Further, in order to enable filter screen structure can be slided easily in the annular groove 140, implement at one
In example, as shown in figure 5, the side wall of the annular groove 140 circumferentially offers sliding slot 150, the filter screen mounting plate 320 is along week
To sliding block 321 is provided with, the sliding block 321 is slideably positioned in the sliding slot 150, that is to say, that the filter screen mounting plate
320 are slideably positioned in the sliding slot 150, that is to say, that the filter screen structure is slideably positioned in institute by the sliding block 321
It states in the annular groove 140 of nozzle 100, by the setting of the sliding block 321 and sliding slot 150, enables filter screen structure in ring
Sliding rotation in shape slot 140, so that it is more convenient to use, while reducing the friction with the side wall of annular groove 140, increase institute
State the service life of filter screen structure.
For example, in order to enable the filter screen 310 for being inserted in the annular groove 140 can be connected to first shunting
Two parts are divided on the side wall in road 110 and just by the first runner 110, and the cross sectional shape of first runner 110 is answered
The shape with the filter screen 310 is identical, for example, the cross sectional shape of first runner 110 is fan annular, so that described
Filter screen 310 can be inserted into first runner 110 and the side with runner close to the axle center by the annular groove 140
Wall abuts, and is filtered by filter screen 310 with ensure that the plastic uniform by first runner 110.
For example, in order to enable the filter screen 310 for being inserted in the annular groove 140 can be connected to first shunting
Two parts are divided on the side wall in road 110 and just by the first runner 110, and the cross sectional shape of first runner 110 is answered
The shape with the filter screen 310 is identical, for example, the cross sectional shape of first runner 110 is fan annular, so that described
Filter screen 310 can be inserted into first runner 110 and the side with runner close to the axle center by the annular groove 140
Wall abuts, and enables and is equably filtered by filter screen 310 by the plastic cement of first runner 110.
Further, in order to enable shunting uniformly, that is, make filter effect more uniform, for example, described first point
The width of runner 110 is equal to the width of second runner 120, for example, first runner 110 and described second shunts
The width in road 120 is respectively less than the width of the sprue 130.
Further, into the melt plastic cement of the first runner 110 and the second runner 120 because of the resistance of filter screen 310
Power and have lost partial pressure, in order to make up the pressure of loss, for example, first runner 110 and second runner
120 width is all larger than the width of the sprue 130, for example, the width of first runner 110 is equal to described second point
The width of runner 120, and the width of first runner 110 and second runner 120 is all larger than the sprue 130
Width so that from the first runner 110 and the second runner 120 cross into sprue 130 melting plastic cement because by
It squeezes and increases pressure, to make up the pressure lost by the filtering of filter screen 310.
For example, in order to enable the sealing effect of the nozzle 100 is preferable, that is, make the plastic cement of melting will not be from filtering
It is leaked out between web frame and the gap of the annular groove 140, in one embodiment, the outside of the nozzle 100 is provided with close
Big envelope, the sealing shroud are connected to the filter screen mounting plate 320, so that the nozzle 100 has preferable sealing effect.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
