In the utility model, when needs filter melt, under hydraulic oil cylinder driving, draping post inserts in draping seat and carries out melt filtration, and the utility model will pass through first of melt, second filter screen blocks design becomes the circular arc porous plate of semicolumn housing shape, the filter area of this circular arc is greater than the filter area of straight plate shape, it can make plastic melt flow to mould from the circumference all directions of circular arc porous plate, achieve the maximization design that melt flow flows into mould, filter effect simultaneously in order to enable plastic melt obtain, the filter screen overlapped with it is provided with before circular arc porous plate, make plastics first from strainer filtering once, enter porous plate again to filter, realize double filtration.
Described draping seat comprises charging aperture and discharging opening, is provided with the runner that be communicated with corresponding to the second runner first flow between described charging aperture and discharging opening.
In the utility model, the first draping post and/or the second draping post insert the filtration that could realize melt after in draping seat, and mainly melt enters first flow and the second runner from charging aperture by the runner shunting of draping seat, then flows out from the runner near discharging opening.
Although utility model people also finds that in actual production the double filtration of the first filter screen block and the second filter screen block can meet the filtering requirement to melt in production, but in order to make melt evenly, plasticity is further improved, filter effect reaches best, can be provided with the three filter screen block relative with the first filter screen block in described first draping post, described 3rd filter screen block comprises the three-arc shape porous plate and three-arc shape filter screen that overlap; In described second draping post, be provided with the four filter screen block relative with the second filter screen block, described 4th filter screen block comprises the 4th circular arc porous plate and the 4th circular arc filter screen that overlap.
In same runner, by this multi-filtering structure of relative filter screen block, multi-filtering multiple-contact is carried out to melt, make the plasticity of melt reach optimum efficiency, more evenly.
Described draping seat is also provided with some heating rods.
Compared with prior art, the beneficial effects of the utility model are:
1. the circular arc filter screen arranged and circular arc porous plate can increase the flow that melt passes through greatly, and resistance is also little, makes the little twice of the comparable old-fashioned size of this circular arc net-changing device overall dimensions, save a large amount of manufacturing costs, and the minimizing of area of dissipation, saves the loss of the energy.
2. the multi-filtering structure arranged makes melt further increase uniformity and the plasticity of melt when ensureing large discharge, slight drag.
