In Figure 11, Tu13Zhong, the other parts of moulding system, such as baffle plate, alignment pin, exhaust chamber etc. are not shown,
The part being not shown can be chosen according to existing V methods Modeling Technology.
The formative technology of V method moulding systems is providing exhaust chamber and aspirating hole template or model first, then will baking
It is covered in each apperance in the eva film of mecystasis, is evacuated by vavuum pump, film is closely attached on template and be molded.EVA is thin
Film may also be other suitable plastic sheetings.
Combined in the forklift hole of the paint of the core 6 drying insertion evaporative pattern 5 that will be made, in the forklift hole of evaporative pattern 5
The two of core 6 can reserve the core print of 100~150mm.
Holistic evaporative pattern 5 is would be combined into again and core 6 is placed on the apperance top of the top box apperance 2 for having covered film, by
The cooperation alignment pin of top box apperance 2 and evaporative pattern 5 is fixed, and rising head 51 is finally placed on evaporative pattern 5.In top box after the completion of combination
Uniformly coating is sprayed on the film and evaporative pattern 5 and rising head 51 of apperance 2；Then, the sandbox with filtering suction pipe is placed on
Cover on the model of eva film, to drystone sand is filled in sandbox 20, any binding agent or additives be not added with quartz sand,
Make sand consolidation by means of microseism, strike off, put notacoria 72, open valve and pump air in molding sand using vavuum pump, make external memory in casting mold
In pressure differential.Because the effect of pressure differential makes casting mold be molded and with hardness higher, the moulding of sand mold in completion.
The moulding of lower sand mold 8 similarly, is providing exhaust chamber and aspirating hole template or model first, then will baking
It is covered in nowel apperance 3 in the eva film of mecystasis, is evacuated by vavuum pump, film is closely attached on template and be molded.
Eva film may also be other suitable plastic sheetings.Sandbox 30 with filtering suction pipe is placed on and has been covered under eva film
In case apperance 3, to drystone sand is filled in sandbox, any binding agent or additives are not added with quartz sand, sand consolidation are made by means of microseism,
Strike off, put notacoria 82, open valve and pump air in molding sand using vavuum pump, make the presence of pressure differential inside and outside casting mold.Due to pressure
The effect of power difference makes casting mold be molded and with hardness higher, completes lower sand mold moulding.Finally poured into a mould with upper sand mold mould assembling.
Referring to Figure 14, casting mold system is used to produce the casting 1 with forklift hole, including upper sand mold 7 and lower sand mold 8, upper sand mold 7
Mold cavity surface with lower sand mold 8 is covered by plastic sheeting 71,81 respectively, and casting mold system also includes core 6 and evaporative pattern 5, disappears
Mould 5 is the orifice of the fork truck bore portion 12 of correspondence casting 1, and core 6 is seated in the hole of evaporative pattern 5, the two ends embedment of evaporative pattern 5
In upper sand mold 7, the mold cavity surface of upper sand mold 7 is combined into the shape of the second side surface of casting 1 with the outer surface of evaporative pattern 5, under
The mold cavity surface of sand mold 8 has the shape of the first side surface of casting 1.
The casting mold system shown in Figure 14 is reviewed, core 6 is only contacted with casting forklift hole inwall, and casting surfaces externally and internally is V
Thin dry sand used by method, reduces scab probability, and easily, polishing amount is reduced cast cleaning.Superimposed core can only bring out in forklift hole two
Now a small amount of burr, solves the defects such as a large amount of burrs that locating core is from top to bottom produced；Model simplification, reduces model system
Make time and model manufacturing expense；Without overlay film on forklift hole, eva film area coverage reduces, and overlay film is uniform, is less prone to thin
Film damages the phenomenons such as gas leakage；Sand core structure is simple, and core easily, saves the time under making core；Eva film and sand will not be produced during mould assembling
The problems such as core contact rotten film of cunning causes crush.Therefore the utility model easily realizes that operation simplifies, during per case casting moulder
Shorten, such castings production efficiency improves 30%~50%, and production cost is effectively reduced to a certain extent, improves work
Make efficiency.
Although the utility model is disclosed as above with preferred embodiment, its be not for limiting the utility model, it is any
Those skilled in the art are not being departed from spirit and scope of the present utility model, can make possible variation and modification.Cause
This, every content without departing from technical solutions of the utility model, according to technical spirit of the present utility model to above example institute
Any modification, equivalent variations and the modification made, each fall within the protection domain that the utility model claim is defined.
