Description
Technical field
The present invention relates to the die of a kind of injection forming method and ejection formation；Particularly to a kind of hydrolysis die for plastic cement ejection formation operation and a kind of hydrolysis die injection forming method for plastic cement ejection formation operation.
Background technology
When the inside somewhat complex design casting carrying out metal product in the past makes, modal processing mode is to adopt dewaxing microcast process.Common dewaxing microcast process mainly contains six steps: 1. wax becomes wax-pattern through ejection formation；2. wax-pattern is combined into wax tree；3. form shell mould；4. dewaxing；5. solidify after molten metal is injected shell mould；6. crack shell mould and obtain foundry goods blank.Can the outward appearance of wax-pattern and size can directly affect shell mould produce the foundry goods met the specification, and the efficiency that wax-pattern produces in addition also can affect the ability of a large amount of casting.But the technique of wax-pattern is subject to the inflexible limit of metal material and there is many problems and challenge, for instance: filling is not full, current mark, depression and deformation etc., and these problems generally have to repair via secondary operations, cause extra production time and cost payout.
Conventional lost-wax process also attempts to be applied in the plastic cement field that ejection formation is conventional, but, owing to wax has bigger cubical contraction, wax-pattern is susceptible to contraction problem, and the high temperature of heating easily dissolves in the plastic material of injection when dewaxing, this is also dewax not easily to be used in one of plastic cement problem penetrating making.Additionally, wax material itself is also the non-conductor of heat, therefore wax-pattern is susceptible to solidify not enough and produce surface pitting defect, causes the yield that plastic cement penetrates not good.
In order to solve the problems referred to above, inventor, via researching and developing experience for many years, finally proposes a kind of without high temperature dewaxing technique, just can make the plastic cement ejection forming technique of exquisite internal structure at lower cost.
Summary of the invention
Up to now, when industrial circle makes plastic cement injection finished product, use repeatedly is penetrated and die change fabrication techniques complex internal structure more；The present invention then adopts hydrolysis die and plastic cement injection forming method thereof to produce complicated plastic cement injection internal structure, not only can reduce process costs and manufacturing time whereby, and have higher production yield.
One embodiment of the configuration aspects of the present invention is a kind of hydrolysis die, and this hydrolysis die is used for molding injection product, and aforementioned hydrolysis die includes hydrolysis body and at least one hydrolysis rinse part.Hydrolysis body is used for the internal structure of molding injection product.Aforementioned hydrolysis rinse part integrally links and has end face with hydrolysis body, and the extension of aforementioned end face exposes and is not shot up product and covers, and the area of end face accounts for the 3%～50% of hydrolysis bulk area.
By aforementioned embodiments, the present invention can utilize the complex internal structure of this hydrolysis die ejection formation injection product, again with aforementioned end face quick flush or spray into steam with decompose this hydrolysis die, after hydrolysis die complete hydrolysis is rinsed, the complex internal structure of injection product has just completed and has completed cleaning work in the lump, so the hydrolysis die of the present invention can produce ejection formation internal structure, and keep lower cost and shorter Production Time.
Other embodiments of aforementioned hydrolysis die embodiment are as follows: the hydrolysis rinse part of aforementioned hydrolysis die can be rinse post, this rinses post and links and outwardly extension with hydrolysis body one, aforementioned end face is positioned at outside flushing post, can produce the labyrinth being hidden in injection product whereby.It is noted that aforementioned flushing post can have multiple and equal distribution on hydrolysis body.On the other hand, the hydrolysis rinse part of hydrolysis die can be rinse groove, rinses groove and is integrally opened on hydrolysis body, and aforementioned end face may be located at flushing bottom portion of groove or periphery.Additionally, the injection product of aforementioned hydrolysis die can separately have several outage, the use that liquid when the corresponding hydrolysis body of outage is available for rinsing hydrolysis discharges, so borrowing outage design can accelerate hydrolysis developing technique.Preferably, the area of above-mentioned end face accounts for the 10%～30% of hydrolysis bulk area.Most preferred, the area of above-mentioned end face accounts for the 3%～10% of hydrolysis bulk area.
One embodiment of the method aspect of the present invention is a kind of plastic cement injection forming method being hydrolyzed die, and the present invention is used for ejection formation injection product.The plastic cement injection forming method of hydrolysis die comprises the following steps: molding hydrolysis die；Hydrolysis die is reserved hydrolysis rinse part, and hydrolysis rinse part has end face；Ejection formation next-door neighbour is hydrolyzed the injection product of die, and end face exposes to injection product and is not shot up product and covers；Carried out water or steam washing by end face, cause hydrolysis die from end face by complete hydrolysis；And rinse injection product.
By aforementioned embodiments, the present invention can quick Fabrication go out to have the injection product of internal labyrinth.And other embodiments of aforementioned embodiments of the present invention are illustrated in down.The plastic cement injection forming method of aforementioned hydrolysis die can include ultrasonic vibrating hydrolysis die, once again to accelerate the flushing speed of water or steam.The hydrolysis die additionally, can heat in the plastic cement injection forming method technique of hydrolysis die, the flushing speed of equally possible quickening water or steam.
In a word, according to hydrolysis die provided by the invention and plastic cement injection forming method thereof, the present invention can form the complex internal structure in injection product under the requirement of lower cost and relatively short processes time.The internal structure of injection product can also be cleared up effectively in the lump, be strictly a kind of entirely novel invention technology that can overcome conventional known predicament.
