Description
Technical field
The present invention relates to the method and apparatus cast in sand mo(u)ld, the feed of casting mould is more particularly related to
System.
Background technology
In order to obtain casting by moulding, mould (being generally made up of sand) is used, the mould includes：
- (being used for part) main chamber, the main chamber adapts to the shape and size of part to be manufactured, increases volume adequacy, make
Molten product at room temperature is obtained to adapt in shape and size so-called " thick mo(u)lded piece ".These chambers by moulding work accordingly
Has (mould plate and core box) formation.
- fill system, is poured into a mould the molten metal alloy or molten metal of constituent part by the fill system.The filling
System is made up of one group of conduit, pipeline and room that can connect the outside of mould with the chamber corresponding to part.
- feeding system (rising head (standpipe, riser) or small-sized rising head), the feeding system allows in the molten metal
Cooling period is to main chamber supplying melting metal.
- chill casting room (chill mold, chills).In some parts, in order to ensure it is determined that part in do not shrink
Defect (contraction), it is necessary to have insert (being made up of metal or graphite), to accelerate the region of part to consolidate in a mold
Change and refrigerating mode.This is common way in casting because it is determined that part in, this is to ensure that up to specification unique
Or best mode.
Fig. 1 generally illustrates the element for constituting casting mould.
Series of steps or stage are needed by moulding manufacture mo(u)lded piece (cast member, casting)：
- design.Calculate and checking filling and feeding system, to make part up to specification.
- molding.Using by constituting the mixing being combined together to form with the sand of characteristic by different systems with different
Thing, to obtain mould.
- casting.Liquid alloy is introduced into mold cavity by fill system.In order to complete the filling of mould, it is necessary to make conjunction
Golden " overheat ", and this overheat will primarily depend upon the thickness of part to be manufactured.Inner body will need higher overheat temperature
Degree.
- solidification cooling.Alloy is set to be cooled down in mould until its solidification.Solidification is critical stage, because feeding system must
It must can offset the contraction that casting alloy is undergone.
- mould separating (release).Part, i.e. feeding system and fill system are removed from the molds, it is necessary to destroy sand mo(u)ld.
Therefore, the feeding system correctly designed allows for offsetting the contraction occurred during cooling liquid state metal.It is actual
On, solidification or state change are carried out in two stages：
Cooled down under-liquid.This corresponds to casting temperature TCWith solidification start temperature TLBetween interval.
Cooling in-solidification interval.This refers to the contraction for solidifying the metal between beginning and end temperature, i.e. TL-TSBetween
Interval.
The response of feeding system corresponds to the response of the summation for two contractions being previously mentioned, once because metal is complete
Into solidification, feeder apparatus cannot add metal.
Feeding system, in other words, rising head and small-sized rising head can occupy two entirely different positions in a mold：
- at top.In these cases, feeder apparatus is directly rested on part to be fed, but it can have
Holder Fasteners or separation ring (biscuit (biscuit)).
- in side.In these cases, feeder apparatus is located at side, and passes through so-called " cannula base or rising head
Nest " realizes the connection of the feeder apparatus and part.Riser base (riser base, riser base) is deposited in mould inside formation
The space of thing or chamber (generally with sizable size), it must be occupied with by the rising head in casting by liquid metal
Metal connected with part, and offset the contraction that the metal of part undergoes in its solidification process.As already mentioned, the function
It is referred to as feed, and it is only just meaningful in the liquid phase, just cannot added material because once solidifying.
In order that riser base can realize its function, in other words, in order that during fluid compartments part and rising head it
Between exist connection, it is necessary to solidify part first, then solidify riser base, finally rising head is solidified in itself.This solidification is suitable
Sequence ensures not shrink defect (contraction) in part, so that the part is unavailable.
The dual platen (match plate, match plate) for being commonly used for obtaining the internal structure of sand mo(u)ld produces part to be manufactured
With the chamber of riser base so that the sand mo(u)ld obtained for mould plate shape and riser base chamber duplicate.Therefore, rising head is formed
The chamber of nest is made up of the remainder identical material (silica sand usually combined using different system) with mould.
Therefore, in order to ensure the solidification more late than part of the metal in riser base, not using other non-volumes and geometry
Alternative, in other words, larger size is presented in riser base, and this has on net performance/overall performance significantly affects.
Specific to riser base, there are many limitations in existing method, and most noticeable limitation is as follows：
The chamber of-the pedestal for corresponding to rising head by being made with part identical molding-system (is usually silica sand, silica sand uses institute
The system that the casting of discussion is used is combined).
- its hot property is similar with the hot property of the remainder of mould, therefore, and it is without extra heat-insulated/heat energy power.
- necessarily must be solidified after part due to it, therefore in order to compensate the hot property that its is not enough, take body
Product and geometry.
- net performance/overall performance is quite unfavorable, and net performance/overall performance is crucial in terms of manufacturing cost.
- due in the riser base middle live part for having used liquid metal, therefore the life represented with every mo(u)lded piece in itself
Yield becomes negatively affected.As long as net performance/overall performance is optimized, productivity ratio is improved.
Once-part from mould depart from, then in view of part to be cut is excessive, by riser base separated with part to
It is highly difficult less.
The big quality properties of-routine riser base design also have negative effect to the metallurgy condition of part, because office
Portion's thermal stress is very high.
- due to cut portion it is excessive (height), therefore the separation of riser base and part generates obvious cracking risk.
