The continuous model casting device of metal
Technical field
The utility model belongs to the metal pattern casting device, relates in particular to the device of working continuously of moulding, casting and the conveying of casting.
Background technology
Current, the metal pattern casting tinuous production of production identical parts is made of continuously vertical moulding machine, conveying platen, synchronous clamping device, scale conveyer and vibratory shakeout machine, carry the platen both sides that the synchronous clamping device of certain group of number is set, casting ladle is suspended from carries the platen top.The sand mold that vertical moulding machine is made, be pushed out to the discharging platen by the pusher that is provided with in the moulding machine, clamping device presss from both sides sand mold singly to carrying on the platen synchronously, sand mold of every release, the action that clamping device just will repeat clamp-mention-move forward-unclamp-to retreat, sand mold is just transported continuously to scale conveyer, vibratory shakeout machine and is moved, and sand mold is cast in moving process, realizes that sand mold moulding, casting, sand mold are carried and cleaning is carried out continuously.Its shortcoming is: sand mold moves by lazy-tongs clamping and moves, and to falling into the clampings repeatedly that the scale conveyer will experience up to a hundred times, the sand mold badly broken influences casting quality from the discharging platen for sand mold, and qualification rate is low; Sand mould material, molten iron and power consumption height; Control program and equipment complexity, travelling speed is slow, fault is many, and the influence casting is produced and carried out smoothly.
Summary of the invention
In order to overcome the defective that prior art exists, the purpose of this utility model provides a kind of continuous model casting device of metal, avoids sand mold to fall away accident and takes place, and reduces sand mold and damages, and improves product percent of pass; Reduce sand mould material, molten iron and power consumption; Improve travelling speed, increase work efficiency, guarantee to produce and carry out smoothly.
The continuous model casting device of metal, constitute by the vertical moulding machine, apron conveyer, vibratory shakeout machine, sand sieving machine and the casting ladle that connect successively, characteristics are that the discharging platen top of vertical moulding machine is provided with stabilizing mechanism, push down sand mold when pusher retreats, and prevent that sand mold from falling away accident and taking place; Establish chain scraper conveyor between vertical moulding machine and the scale conveyer, the carrier bar of chain scraper conveyor and discharging platen be tangent intersecting at the great wheel place, the sand mold that pusher is released places on discharging platen and the carrier bar, the surface of discharging platen and carrier bar is in the same plane, pusher promotes sand mold and steadily moves, and sand mold drives carrier bar and orbits; Removable mounting sand mold seat board on the chain scraper conveyor, when starting shooting for the first time, removable mounting is on carrier bar, and the stable several sand molds that begin to release prevent the sand mold overturning.
Described stabilizing mechanism is connected and composed by portal and hydraulic cylinder, column and crossbeam connect into portal, column is located at discharging platen both sides, hydraulic cylinder is fixed on the crossbeam, and pressing plate is connected the free end of hydraulic cylinder, the lifting of Driven by Hydraulic Cylinder pressing plate, pressing plate descends, push down sand mold, pressing plate is mentioned, and unclamps sand mold.
Described sand mold seat board vertically is connected with base plate by riser, and brace supports, and is connected on riser and the base plate; Establish pin hole on the base plate.
Described chain scraper conveyor is connected and composed by support, track, great wheel, tail wheel, roller and carrier bar, and great wheel and tail wheel are located at the support two ends, and track is located on the support; Carrier bar and carrier bar be end to end to become the revolution loop chain, places on great wheel, tail wheel and the track, and tail-gear spindle also is provided with tail wheel reversing drive unit to the side, is connected with tail wheel during the reversing carrier bar, auxiliary carrier bar reversing, when normally moving tail wheel with reverse drive unit and separate.
Described carrier bar is connected to form by flat board, chain and axle, roller; Flat board is established and is established bolt hole on bolt hole and the chain and match, by bolting; Also establish pin hole on the flat board, match, fix by latch with pin hole on the base plate of sand mold seat board; Axis hole is established at the chain two ends, and roller is by the two ends of bearing fixing at axle, and axle is fixed on the chain by steel bushing, is connected by axle between two carrier bars;
Distance between described two rollers equates that with distance between great wheel, adjacent two teeth groove of tail wheel two rollers, two teeth groove adjacent with great wheel/tail wheel adjacent when guaranteeing to rotate mesh.
The casting production process is: sand mold seat board removable mounting on carrier bar, to block the several sand molds that begin to release, is avoided the sand mold overturning.When the sand mold that moulding machine is made was pushed out to the stabilizing mechanism below by pusher, stabilizing mechanism pressed down, and pusher is return, and carries on the stabilizing mechanism then; When the 2nd sand mold is pushed out to the stabilizing mechanism below, promote the 1st sand mold reach, shift out stabilizing mechanism after, stabilizing mechanism presses down again, pushes down the 2nd sand mold, pusher retreats, stabilizing mechanism is carried on again, so repeatedly carries out continuously, sand mold drives the carrier bar reach.When the sand mold arrangement runs up to the 10-15 piece, begin the molten iron of casting, and remove the sand mold seat board, moulding, casting, conveying are proceeded.When sand mold entered the chain scraper conveyor end, sand mold fell on the scale conveyer, delivers to vibratory shakeout machine, clear up, and foundry goods and sand separation, sand is recycled through screening.
Compared with prior art, advantage is novel structure, compactness, rationally, avoids sand mold to fall away the generation of accident, does not have displacement between sand mold and the carrier bar, and sand mold steadily moves continuously, significantly reduces the sand mold breakage, improves casting quality, improves product percent of pass; Reduce sand mould material, molten iron and power consumption; Control program and simplified equipment, handled easily has improved equipment availability efficient, and travelling speed improves more than three times, improves work efficiency, and assurance moulding, casting, conveying and casting cleaning are carried out smoothly.
