Cope 7 is fixed on the lower section of crossbeam 8.Cope 7 and drag box are corresponded to about 6 and laid.Lower sand shooting mechanism 9 is connected with crossbeam 8, under
Penetrate sand mouthful sealing and sand block inflatable body is arranged on lower sand-shooting head 9-1 (see Fig. 5).Upper sand shooting mechanism 10 is connected with crossbeam 8.Mould
Sheet frame shuttle mechanism 14 is connected with column 3, and pattern plate bolster and floating installation 13 are located in pattern plate bolster shuttle mechanism 14.Pattern plate bolster shuttles
Mechanism 14 is located at the top of drag box 6.Template quick change is passed in and out and elevating mechanism 17 is connected with crossbeam 8, template quick change holding structure
18 are arranged on the rear portion of base 2, the outside of column 3.
The moulding machine work of said structure is as follows：Referring to Figure 20 and Figure 21, the pattern plate bolster equipped with upper mould board passes through four
Floating installation is supported, is placed in template shuttle mechanism 14, moulding station is sent into by template shuttle mechanism, the sand mold made is released.
Original lower drawing plate 601 for holding up sand mold, drops to the bottom of drag box 6, the antisymmetric upper limit in both sides on crossbeam 8
Two gag lever posts 1203 of mechanism 12 are extended downwardly from, meanwhile, the annular piston 402 in the first combination 4 rises, and passes through both sides jacking block
407 rise the synchronous jack-up certain altitude of four guide rods 602 on drag box, then drag box 6 with lifting press mechanism 1, lower sand

Case 7 and drag box 6 are penetrated sand and terminated to sand is penetrated.The sand grains that may be scattered is removed in the air blowing of side blowing nozzle 909, it is ensured that sealing frame is smoothly moved back
Go back to original position.
Referring to Figure 21：Sand block plate 904 declines, and upper limit bar 1203 is retracted, lifting system for compacting 1 enter hydraulic oil, continue to
Upper lifting, goes up sand mold in place, the then lower end oil extraction of annular piston 402 declines by pattern plate bolster cope match plate to cope internal pressure is real, by
Drag box 6 is held in lifting system for compacting to continue to rise, making pattern plate bolster mould board, lower sand mold in place, is completed in fact to drag box internal pressure
Template is compacted upper and lower Sand Moulding Process process.
Lifting system for compacting 1 declines, and pattern plate bolster together declines with drag box 6, cope molding.Mould is dropped under pattern plate bolster
On the air supported head of sheet frame and floating installation 13, after being blocked, stop declining, drag box 6 continues to decline, lower sand mold molding.Template
Frame 13 exits moulding station with pattern plate bolster shuttle mechanism 14.Lower core outside the shuttle removal machine of drag box 6 of type is made, under a upper circulation
The drag box of good core, which shuttles, enters moulding station.Lifting system for compacting 1 rises again so that cope and drag box mould assembling.On
Through-rod piston 1102 in sand mold drawing mechanism is driven and pushed away under upper drawing plate 701, and upper sand mold is released downwards.Upper sand mold drawing mechanism
In synchronizing bar 1104 downwards when touching drag box die joint, lifting system for compacting 1 declines, get togather the drag box 6 of type with
With decline.Lifting system for compacting 1 declines buffering and stopped in place.Upper sand mold drawing mechanism through-rod piston 1102 rises, and is taken off in drive
Boxboard 701 is retracted upwards.Drag box drawing plate 601 rises the upper sand mold and lower sand mold that ejection gets togather type.So completion one is complete
Whole working cycles.
