Pass through above-mentioned technical proposal, when filtering platform is extend into conveying channel bottom, screen pack can lead to conveying just Road overlaps, because screen pack is identical with conveying channel diameter so can be filtered completely to the liquid plastic in conveying passage, simultaneously So design can also save the material for making screen pack, economize on resources and save fund input.

The utility model is further arranged to：The fixture includes gag lever post and fixed plate, the uniform cloth of fixture Four Angle Positions at the top of the filter chamber are put, the fixed plate is fixed on the gag lever post, and the hydraulic cylinder is fixed on On the fixed plate centre.

Pass through above-mentioned technical proposal, gag lever post position is arranged so as to, the more firm stress of the object for supporting gag lever post is more Add uniformly, the advantages of hydraulic cylinder is fixed on fixed plate centre be when hydraulic cylinder works, can be with more stable to filtering platform Stretched and shunk.

In summary, the utility model has the advantages that：

1st, this utility model can come out the contaminant filter in liquid plasticses, make the final product quality of making more preferable；

2nd, the filter of this utility model can be promoted or extracted out by hydraulic cylinder, can more easily change screen pack.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Embodiment：A kind of injection machine, as shown in figure 1, including fuselage 1, on the fuselage 1 provided with pan feeding chamber 12 and heating furnace 11, plastic grain is added in pan feeding chamber 12, passes through hydraulic drive（Announce in TYD88C type injection machines and do not discussed again）, Blanking particle is sent into heating furnace 11, plastics are heated in heating furnace 11, when the temperature in heating furnace 11 reaches a constant temperature Plastic grain, which starts to melt, after degree turns into liquid, and the plastics for turning into liquid flow into filtering under hydraulic drive by conveying passage 13 In chamber 14.

As shown in Fig. 2 being provided with filter 2 on the top of filter chamber 14, filter 2 includes support frame, and support frame includes Four gag lever posts 21 and one piece of rectangular retaining plate 22,21 uniform symmetrical arrangement of gag lever post are fixed on the upper plate of filter chamber 14, Rectangular retaining plate 22 is fixed on gag lever post 21, and a hydraulic cylinder 23, piston rod 231 are fixed with the centre top of fixed plate 22 The circular hole that the middle part of fixed plate 22 is provided with is extended through, a top cap platform 24 is connected with piston rod 231, in top cap platform 24 Heart axis direction is provided with a circular groove 242, and the bottom plate 243 of circular groove 242 is provided with some through holes（See Fig. 4）, it is circular recessed Isodiametric circular filter net 3 is provided with groove 242, screen pack 3 is frictionally held in recessed by generation between circular groove 242 In groove 242.
