For the prefabricated thin-wall exhaust passage that contains two or more through holes, the moulding process unanimity, in adventitia, comprise one or more cores that constitute by upper and lower core 6,6a cooperation during die assembly, corresponding formation single hole element mold or porous member mould, core is equipped with the end frame 3 consistent with the die cavity shape and structure with the die cavity two ends that adventitia constitutes.Figure 1 shows that the single hole mould, Fig. 4 is the diplopore mould.
The moulding process of using above-mentioned mold for shaping prefabricated thin-wall exhaust passage manufacturing exhaust duct may further comprise the steps:
1) die assembly, and, the mould that combines is hung traction track with the reinforcing bar of colligation moulding, the relevant position that electrowelding net sheet skeleton places mould, the traction by pulling equipment is dragged to the edge of table of shaking, and hangs on the platform that shakes fixing by lifting appliance again;
2) open shake table, casting cement mortar in above-mentioned mould, cement mortar is evenly enriched each space of being preset in the mould by vibration force in mould, and pour into an integrated entity with reinforcing bar, net sheet skeleton, the weight proportion of described cement mortar is a cement: 25%, sand: 74.5%, water reducer 0.5%
3) behind the casting complete, product and mold integral lift by crane on the track of curing kilns, and the cement mortar of upper surface is modified, and are trimmed to straight bright and clean back and by hauling machine product and mold integral are led the place of resting in the curing kilns, and rest 30 minutes;
4) product and mold integral are led maintenance place maintenance in the curing kilns, curing temperature after resting: 50~70 ℃, curing time: 5.0~7.0 hours;
5) after the step 4) maintenance, product and mold integral be drawn to cooling wait place cooling in the curing kilns, be 30 minutes cool time, carry out form removal then, go out to transport to open storage ground after product is split out and carry out natural curing from mould, the natural curing requirement of strength is 85-100%.
The die assembly process is: stile mould fixed bar 1 is propped up in the left and right sides on bed die 19, snaps in, fixing dual-side mould 2, at two ends or needed design length stiff end frame 3 again; With the reinforcing bar of colligation moulding, the relevant position that electrowelding net sheet skeleton places mould, will descend core 6a to put in the end frame 3 then, the adjusting screw(rod) 22 of rotation core frame jack 8 is adjusted core 6a down
Figure G2009201130308D00071
The open configuration of core framed 10 makes core frame 10 sides and end frame 3 inner edge position consistency; From the core 6 that pushes suitable for reading, same core frame jack 8 is adjusted the open configuration of core frame 10 again, makes itself and end frame 3 inner edge position consistency; Last core 6, the tight sturdy cooperation of following core 6a constitute core.For two holes or the porous mold more than two holes, in adventitia, get final product by propping up upright core one by one by said process.
Its form removal process: the adjusting screw(rod) 22 of the core frame jack 8 of core 6 in the rotation, spurring forward and backward center pull rod 15,15a simultaneously moves to the inside, become " V " shape structure two pulling-on pieces 14 to close up to the center, pulling left and right side pull bar 13,13a inwardly are subjected to displacement, inwardly draw in core frame 10 both sides, upper end neutral gear between the gusset 11 in both sides produces crooked to upper process, last core 6 drops on down in the core 6a, can will go up core 6 and take out; By core 6a under core 6a core frame jack 8 draws in down, core 6a is shelved on the internal backplane of shaped component, thereby extracts out from the inside of type member easily again.
For the prefabricated thin-wall exhaust passage that contains two or more through holes, the moulding process unanimity, in adventitia, comprise one or more cores that constitute by upper and lower core 6,6a cooperation during die assembly, corresponding formation single hole element mold or porous member mould, core is equipped with the end frame 3 consistent with the die cavity shape and structure with the die cavity two ends that adventitia constitutes.
In the foregoing description, the weight proportion of cement mortar can be by cement: 17~31%, and sand: 68~82%, water reducer 0.4~0.6% is selected cooperation for use; Respectively can be in the curing kilns by 35~50 minutes time of resting at the place of resting, the curing temperature of maintenance place is that 50~70 ℃, curing time are 5.0~7.0 hours, be to select for use in 35-55 minute the cool time of cooling wait place, can obtain same technique effect.
