Description
Technical field
The present invention relates to the technical field that casting industry adopts the tide mould sand moulding, particularly a kind of styling apparatus and formative method with sand molding.
Background technology
Because automobile, railway, metallurgy, wind-powered electricity generation, mine all are the great industries of foundry goods demand; And these industries just in time are industries with the fastest developing speed in China at present; Thereby make the fast development of Chinese Foundry industry; Now China has been castings production state the biggest in the world, and output is several times of U.S. of being number two! But the casting of the China equipment level of production is relatively backward, and need the various mo(u)lding lines of import and nearly hundred covers of styling apparatus every year, almost is several times of the whole Europe and the U.S. annual mo(u)lding line amount of purchase summation.
At present; The modern style line generally is divided into two big types, and one type is the flask molding line, when mainly being moulding; General two molding flasks (top box, a nowel) that adopt come moulding; Generally be horizontal parting, the only a few molding adopts 3 and comes moulding with cope, need carry, pour into a mould and cool off with molding flask after the moulding; Another kind of is the removable-flask moulding line; After mainly being moulding; Need not carry sand mold, cast and cooling with molding flask; Wherein be divided into two big types of horizontal parting and vertical-partings again, the mould on end line generally is used for simple shape, the loam core is few, efficient is high product, can not produce than higher and complicated foundry goods; And horizontal parting can be produced nearly all foundry goods, but investment is big, complex equipments, and production efficiency is lower.
The main technique flow process of flask molding line is following: adopt two molding flasks, made upper mold and lower mold during moulding respectively, then upper mold and lower mold are transported to core and inspection casting mold quality under the core setter position.Get into closing machine then with top box and nowel mould assembling, load onto the case card by top box card machine after the mould assembling, prevent to rise case with lift case (adopting Fe-pressing machine to add foundary weight sometimes); Get into the cast of cast station then; Cast back molding flask gets into the cooling section cooling; Cooling is also opened and is got into punch-out equipment behind the case card casting mold is disclosed into the shakeout knockout; Empty molding flask is transported to flask separator after cleaning through the sandbox scavenging machine, and top box and nowel are separated, and it is reconfigured to prepare to get into moulding machine.The flask molding line is to use the widest mo(u)lding line of face, concentrates at present the auto parts and components that are used to produce engine body cylinder cap, bent axle and camshaft etc., also is applied to the field that tractor, engineering machinery, railway and mine etc. need to produce in enormous quantities foundry goods.Flask molding line practical productivity is at 50-70 type/h at present, and the theoretical productivity of introducing mo(u)lding line is 120 types/h.
But there is following defective in present flask molding line:
1, the present invention does not need two molding flasks to carry after moulding; Mo(u)lding line also just need be for two sandboxes configurations turnover machine, independent closing machine, flask separator, mould assembling card machines, get auxiliary body such as case card machine; Adopt single sandbox to carry casting mold; Fundamentally avoid causing for various reasons two faults (being also referred to as mould shift) that molding flask staggers up and down, thereby reduced the casting wasted product rate;
2, need turnover machine, closing machine, flask separator, mould assembling card machine at mo(u)lding line, get many auxiliary bodies such as case card machine, all there are a lot of actions in each mechanism, and each action all increases a trouble point, causes the mo(u)lding line fault rate high, and production efficiency is low;
3, need turnover machine, closing machine, flask separator, mould assembling card machine at mo(u)lding line, get many auxiliary bodies such as case card machine, those auxiliary bodies directly cause the cost of mo(u)lding line sharply to rise;
Therefore 4, molding flask must be able to be resisted the high pressure of styling apparatus, requires the intensity of molding flask and precision high especially, and molding flask is also as pouring into a mould sandbox, thereby causes the cost of manufacture of molding flask sharply to rise;
5, also as pouring into a mould sandbox, high-precision molding flask is easy to damaged by high temperature liquid iron when participating in cast, and expands with heat and contract with cold at the molding flask of cast front and back molding flask, often also influences the moulding precision of styling apparatus;
6, molding flask is also as the cast sandbox; In when cast, owing to two molding flask surfaces are not cleaned out, molten iron is lifted not enough or the like the reason of the big or design mold thickness of case power, molten iron is usually from the die joint of two molding flasks overflow (be commonly called as is runout); Cause the waste of the molten iron and the energy on the one hand; Cause the casting fin burr to produce in a large number on the other hand, casting defect increases, the feeding difficulty.
The main technique flow process of removable-flask moulding line is following: in styling apparatus, accomplish moulding, following core and mould assembling are disclosed molding flask with casting mold after the mould assembling, then will not have the fixing casting mold of sandbox to release moulding machine, shift onto on the teeming line and carry.On pipeline, accomplish add casing, pick and place foundary weight, steps such as cast and cooling.On pipeline, the mo(u)lding line that has adopts casing technology, utilizes casing to reduce mould shift and the minimizing case that rises, and the employing L type supporting plate that has is realized said function with foundary weight, clear-cut exposed casting mold, the mutual way of pushing of the employing casting mold that has etc. of fully directly adopting that have.Horizontal removable-flask moulding line is mainly used in light casting in the batch process, and general mould dimension is about 300 – 800mm, and practical productivity is at 60 –, 150 types/h, and the theoretical productivity of introducing mo(u)lding line reaches as high as 200 types/h.
There is following defective in present removable-flask moulding line:
1, the removable-flask moulding line generally relies on each mechanism precision to guarantee that the shift rate of upper and lower casting mold is smaller owing to there is not sandbox, relies on the frictional force of upper and lower casting mold to come the inertia of resisted movement, so the shift rate is far longer than traditional case line that has;
2, generally adopt casing technology in order to reduce shift; Promptly on pipeline, adopt special cover punch-out equipment that casing is entangled the casting mold of carrying, lay casing in fact like this and be easy to generate new mould shift, as because inertia etc. cause the casting mold change in location; Casing according to former desired location cover down; Push casting mold on the contrary and move, the casing that adopts in order to prevent mould shift like this, the one of the main reasons that often itself has become mould shift to produce;
3, if adopt casing technology; The casing that adopts generally entangles the die joint position, and general casing also only entangles the height about half of casting mold, and all the other are highly exposed; So just can't resist the case that rises well, all sidedly, thereby cause generation of defects such as casting compactness is not enough, loose;
4, the casing that adopts all is " eight " word casings, and inwall has very big gradient, and it is more convenient to pick and place casing like this; But case relies on the weight of foundary weight and casing fully because opposing is risen, and can not rely on frictional force; In fact cast back upper mold more or less can be lifted a bit; And in a single day lift, Eight characters casing just no longer contacts lower mold, and lower mold will produce the mould shift and the case that rises;
5, adopt the molding of casing, general casting mold also is an Eight characters shape, and this often causes being easy to generate mould shift, sandblast or the like defective in the modeling process;
6, mean level removable-flask moulding line productivity ratio is higher than about 1 times on flask molding line, still, the highlyest also is merely able to reach 200 types/h.

The inwall of single sandbox 19 is vertical with horizontal plane, and the lateral surface of casting mold is vertical with horizontal plane, and the inner chamber of single sandbox and the lateral surface of casting mold are complementary, but makes downward straight-line casting mold first motion extremely in the inner chamber of single sandbox 19.The inwall of cope and drag box is vertical with horizontal plane, and the inner chamber of the inner chamber of single sandbox and cope and drag box is complementary.The inner chamber of single sandbox 19 can be clamped casting mold, can prevent upper mold and lower mold shift.In this example, the inner chamber of single sandbox is cubic build, and casting mold is the tetragonal body that is complementary with cubic build inner chamber.
When moulding, can adopt traditional method of making upper mold and lower mold respectively, also can adopt the way of making upper mold and lower mold simultaneously.
The present invention is placed on casting mold in single sandbox and carries; Without any need for positioner; Directly rely on upper mold and the lower mold that four inner inwalls of single sandbox guarantee the inside can shift; Shake, rock, quicken and slow down even in Transportation Engineering, meet with, all can not produce shift, can reduce the shift rate greatly.
Formative method of the present invention; In a template mechanism; Under the condition of same central guidance system guiding, make upper mold and lower mold simultaneously, rely on the guiding of central guidance system to guarantee that top box and nowel fully on a center line, stopped the possibility of mould shift.Simultaneously moulding machine and closing machine are formed a whole, do not need branch mailbox, mould turnover, mould assembling card fully, get these auxiliary bodies of case card, structure is simplified greatly, and reliability improves greatly, and cost reduces greatly.
Molding flask of the present invention separates with the cast sandbox, and the cast sandbox is not participated in moulding, therefore the precision of cast sandbox and the requirement of intensity is reduced greatly; Thereby reduce cost greatly; The molding flask that a small amount of moulding is used, precision intensity is high, and cost is high; But quantity seldom, so totle drilling cost is significantly less than the traditional design line.
In formative method of the present invention, because molding flask and cast sandbox are separated, the cast sandbox is not participated in moulding, and molding flask is not participated in cast, can thoroughly avoid the damage of high accuracy molding flask, guarantees the moulding precision of styling apparatus.
The present invention adopts single sandbox cast, has only single sandbox during cast, fundamentally just can not have two sordid problems in sandbox surface.And single sandbox is often pressed more solidly between upper mold and the lower mold, the more difficult runout of die joint owing to there is not the restriction of top box and nowel.Even molten iron is gone to the sandbox inwall, also can be limited in the die joint by sandbox.In addition, pour into a mould the back casting mold and expand, not only upwards lift case, simultaneously also to expansion all around, the stressed increase of so single sandbox, frictional force enlarges, and has limited the generation of lifting case conversely.And general casting mold almost all is positioned at single sandbox, therefore can resist the case that rises well.
Formative method of the present invention reduced proper motion process greatly, standard mo(u)lding line theoretical productivity hourly can reach 160 types, and ultrahigh speed mo(u)lding line even theoretical productivity hourly can reach 300 types, almost are 1-3 times of existing traditional design line.
The present invention separates molding flask and cast sandbox, adopts single sandbox to carry casting mold, has solved many shortcomings of present removable-flask moulding line and flask molding line, has possessed both many advantages.In at present known mechanization and automatic molding line, also do not find to adopt the horizontal flask molding line of an independent sandbox, immediate with the present invention is the technology that adopts casing in the horizontal removable-flask moulding line.The common ground of casing and single sandbox is all to have only a sandbox.But casing is gradient, is not vertical, because vertical casing almost has no idea to overlap upper mold exactly, and has no idea to utilize gradient, and the casing position is confirmed near die joint.And casing all puts on pipeline, is that casting mold is motionless, and sandbox cover upper mold can produce the problem of mould shift.And the present invention adopts fixedly casting mold of single sandbox, in order thoroughly to solve the mould shift problem, requires inside styling apparatus the inside or closing machine, directly to accomplish, and is that sandbox is motionless, and casting mold gets into sandbox, can avoid producing the phenomenon of mould shift.
In the present invention, single sandbox is vertical, is different from gradient casing, can resist better and lift case, rise case and mould shift.Because after the casting-up, the case power that rises is big more, and the power that is applied to sandbox is big more, and the frictional force of casting mold and sandbox is big more, and the casting mold upper mold just can not move up like this, and the case power of lifting of lifting the case needs is bigger! And vertical sandbox could not lift by casting mold, thereby can resist the case that rises better! The whole coverlet sandboxes of upper and lower like this casting mold clamping tightly fully can not mould shift.
The present invention once directly accomplishes mould assembling, drawing and casting mold and transfers to the cast sandbox from molding flask in styling apparatus or closing machine, avoided the repeatedly transhipment of traditional design method like this or laid specially that the mechanism that casing brings is complicated, cost is high, be prone to shortcomings such as mould shift and low precision.
More than the disclosed several specific embodiments that are merely the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
