Description

Saving metal material and energy metal type sand-covering casting machine

The utility model is that the collection that is used to produce the various mechanical blank body of castings covers the saving metal material and energy metal type sand-covering casting machine that the coremaking of sand system type is cast into one.

The cylinder jacket of diesel engine of state's inner cylinder liner industry production in enormous quantities at present all adopts spun casting technology and equipment, the remarkable shortcoming of cylinder liner blank foundry goods of producing is: blank is that simple tubular, inside and outside surplus are very big, through thick smart multiple operation processed finished products, stock utilization only about 45% consumes a large amount of metal alloy compositions, the energy, artificial; Inherent quality is variation gradually from outside to inside, the percent defective height; That machining is divided is thick, half essence, fine finishining, process flow are long, and production efficiency is low, the processing cost height; Owing to blank allowance is big, the cutting clamping force is big, not only cuts power, and cutter head consumption is big, and the cutting back is yielding greatly owing to internal stress, the product size poor stability, and processing high grade product rate is low, and most loss of capital of cylinder sleeve factory or benefit are very poor.

The purpose of this utility model is to provide a kind of employing metal mold to carry out the sand new technology, the coremaking of collection shoe sand system type is watered and is made as one, be provided with many types of external mold of a mould and common central mould, program-controlled, gas, electricity, machine integrated multistation saving metal material and energy metal type sand-covering are washed casting machine.

Technical solution of the present utility model is: saving metal material and energy metal type sand-covering casting machine comprises external mold common central mould, single oil cylinder control clasp mould mechanism before and after the body, left and right sides station mould bases, the many types of front and back of mould external mold, left and right sides station, penetrates the sand device, pulls out the part taking mechanical hand, planer-type bedstead, the electric single action of Pneumatic hydraulic PLC, program control control device, it is characterized in that: about being equipped with on the monoblock type bed body by the moving left and right sides station mould bases of air cylinder driven workmanship displacement; The many types of front and back external mold of one mould is housed on mould bases; The external mold full mold that matches with external mold and the common central mould in inner mould core chamber are housed above the planer-type bedstead; The clasp mould mechanism of single oil cylinder control is housed on the mould bases; Movable type is housed below bedstead penetrates sand hopper; The left and right sides manipulator that pulls out the part pickup is housed in bed body one side.

The bed body is the high rigidity Welding Structure of monoblock type, and its top, both sides is provided with three angular length tracks, is provided with the station positioner at intermediate stations, the left and right sides station place of bed body both sides, and the cylinder that drives left and right sides station mould bases is housed at station place, the left and right sides of bed body.Left and right sides station mould bases down either side respectively is equipped with two pairs of triangular groove rollers.Clasp mould mechanism is housed above mould bases, the many types of external mold of a mould is housed on the template of the front and back of clasp mould mechanism, single oil cylinder of driving folding mould is housed at the rear side of clasp mould mechanism.Center die is designed to left and right sides station external mold common central mould, and the oil cylinder that control centre's mould is shifted up and down is housed above bedstead.The rear side of penetrating sand hopper in the handover formula is equipped with the cylinder of magnetic switch setting, the device of strike-ofing automatically is housed penetrating the sand hopper front side, is provided with the Sha Zui that penetrates that aims at inner core chamber, outer die cavity penetrating the sand hopper lower surface.Above manipulator paw, be provided with and pull out the part oil cylinder, rack-and-pinion swing rotary cylinder is housed at the top of manipulator column, the pickup cylinder is housed above mechanical arm.

The utility model working procedure is as follows:

Front and back external mold before working procedure begins on electrical heating center die and the left and right sides mould bases, make Mo Wenda 200-250 ℃, set holding temperature, automatic heat preserving, wherein only start working preceding first mould of external mold needs electrical heating, powered-down subsequently, by casting workpiece heating external mold, the outer die cavity of general left mould bases during electrical heating (or the outer die cavity of right mould bases) has entered intermediate stations, heat temperature raising, constant temperature make mould temperature basis equalization simultaneously with the center die matched moulds, the circulation of promptly starting working is by manually automatically controlled or PLC is program control respectively by associated button control do action.

Working cycles begins:

Install the sand hopper of penetrating of carrying out film sand and moved to intermediate stations center die top, cylinder is depressed and is penetrated sand hopper, make the lower surface penetrate that the plane fits tightly on sand mouth and the matched moulds mould, once simultaneously outside die cavity, the center die inner chamber is penetrated sand, promptly shoot away sand about 2 seconds, penetrating sand hopper lifts and returns, the device of strike-ofing strikes off a small amount of sand that is detained on the profile automatically, fall back on the position and connect stop-off automatically, about one minute, sand mold, the core crust is molded into core, after the die sinking, center die promotes, stay inner core, mould bases is retired (or right) station to a left side, and inspection is the matched moulds casting after blowing down residual sand, after a left side (or right) mould bases withdraws from, right (or left side) mould bases (being heated to temperature) promptly enters intermediate stations subsequently, and center die descends and puts in place, can penetrate sand behind the matched moulds and be molded into the core action, this moment the left station workpiece of casting, cooling, die sinking, left manipulator transposition drops to the workpiece place, clamping, pull out part, on carry, transposition, descend and to put part, the cleaning die cavity is prepared to enter for the second time the center station and is penetrated sand and be molded into core, and right mould bases is finished already and is molded into core and moves returned right working position, the cooling of casting, die sinking subsequently, part is put in manipulator behavior pickup transposition, finish the one action circulation, so continue cycle operation.

The utility model has the advantages that: owing to adopt the cylinder liner blank of metal type sand-covering technique technology with the utility model device fabrication, its spray inherent quality improves greatly, the blank size precision rough surface reaches international standard, can realize few nothing cutting, reduce material consumption, energy consumption greatly, more than 25%, improve blank, metal working cutting production efficiency, help the scale intensification and produce, improve the competitiveness in inside and outside market greatly, the raising economic benefit of enterprises reduces production costs.Because the bed body is designed to the monoblock type Welding Structure; improve the complete machine rigidity; owing in complete machine, be provided with left and right sides station mould bases; the common central mould, penetrate sand device, left and right sides manipulator, gas-liquid PLC electric control gear, clasp mould mechanism, can realize that intermediate stations penetrates sand, system type, coremaking, left and right sides station and be cast into one, process time beat compactness; floor space is little; the production efficiency height, labor strength alleviates, and improves the technology level of casting industry greatly.
