The multistation casting machine
The present invention relates to the casting machine technical field, more specifically to a kind of casting machine with a plurality of stations.
A lot of Al-alloy parts manufacturers during casting mold, apply the strategy of throwing waves of people into action in process of production, and staff of a station pours into a mould melt, and the staff must run back and forth, seems very mixed and disorderly, and operating efficiency is low simultaneously.Some aluminium alloy castings is because its wall has thickness; When utilizing die casting, have only heating on the mould or have only water-cooling channel, cause the degree of crystallinity of each wall of foundry goods and the intensity difference opposite sex big; Influence product quality; Some mould is when cast simultaneously, and it is consistent not take into full account the degree of crystallinity that lets everywhere, causes cast product intensity relatively poor.
Summary of the invention:
The object of the invention is exactly the deficiency to prior art, and a kind of multistation casting machine is provided, and its staff can pour into a mould the mould on a plurality of stations, has improved production efficiency, has saved the factory labor costs; It controls the up-down and the mould temperature everywhere of mould automatically simultaneously, thereby makes product degree of crystallinity better, has improved product quality.
Technological solution of the present invention is following:
The multistation casting machine comprises pouring robot, and pouring robot is fixed on a side of workbench, and annular array is distributed with and is no less than three casting units on the workbench;
The structure of each casting unit does; Be made up of guide rod, compressed oil cylinder, rotary oil cylinder, swivel plate, back seat plate, cast counterdie and cast patrix, back seat plate is fixed on the swivel plate with the cast counterdie, and swivel plate is hinged on the workbench; Guide rod two ends are separately fixed at back seat plate and pour into a mould on the counterdie; Compressed oil cylinder drives the cast patrix and slides along guide rod, and rotary oil cylinder is fixed on the brace table, and the piston hinge of rotary oil cylinder is on swivel plate;
The cast counterdie all forms water-cooling channel in the patrix and is fixed with electric heating tube with pouring into a mould, and water-cooling channel has water inlet and delivery port, the both positive and negative polarity lead electric-connected socket of electric heating tube;
Column one end is fixed on the bottom of workbench, and the other end is fixed on the top of brace table, and the bottom of brace table is equipped with pulley and is fixed with gear wheel; The driven by motor pinion rotation; Pinion is meshed with gear wheel, and pulley is made circular motion along the guide rail platform, and the bottom of guide rail platform is fixed with leg;
People's Bank of China's platform ladder one end is fixed on the workbench, and the other end places on the ground.
Be fixed with positional cylinder on the said guide rail platform, the piston of positional cylinder is facing to pulley.
Beneficial effect of the present invention is:
1, its adopts pouring robot to give die casting, and compressed oil cylinder lets the cast patrix close and close and open with watering counterdie, closes cast when closing; Get foundry goods when opening, pouring robot is poured into a mould on a position all the time, and every cast once; Workbench inserts to next casting unit and pours into a mould, and can realize automation control, and a staff just can accomplish multiple work station pouring; Improve operating efficiency, saved cost of labor.
2, can let mould rotate while pouring into a mould, guarantee that the foundry goods in the mould has crystallization effect preferably.
3, can realize the wall place cooling thin to foundry goods, the intensity that casting pouring comes out is guaranteed in thicker wall place heating.

The specific embodiment:
Embodiment: see shown in Fig. 1 to 6 that the multistation casting machine comprises pouring robot 1, pouring robot is fixed on a side of workbench 2, and annular array is distributed with and is no less than three casting units 3 on the workbench 2;
The structure of each casting unit 3 does; Form by guide rod 31, compressed oil cylinder 32, rotary oil cylinder 33, swivel plate 34, back seat plate 35, cast counterdie 37 and cast patrix 36; Back seat plate 35 is fixed on the swivel plate 34 with cast counterdie 37; Swivel plate 34 is hinged on the workbench 2, and guide rod 31 2 ends are separately fixed at back seat plate 35 and pour into a mould on the counterdie 37, and compressed oil cylinder 32 drives cast patrixes 36 and slides along guide rod 31; Rotary oil cylinder 33 is fixed on the brace table 4, and the piston hinge of rotary oil cylinder 33 is on swivel plate 34;
Cast counterdie 37 all forms water-cooling channel 361 in the patrix 36 and is fixed with electric heating tube 362 with pouring into a mould, and water-cooling channel 361 has water inlet A and water outlet B, the both positive and negative polarity lead electric-connected socket C of electric heating tube 362;
Column 5 one ends are fixed on the bottom of workbench 2; The other end is fixed on the top of brace table 4; The bottom of brace table 4 is equipped with pulley 6 and is fixed with gear wheel 7, and motor 8 drives pinion 9 and rotates, and pinion 9 is meshed with gear wheel 7; Pulley 6 is made circular motion along guide rail platform 10, and the bottom of guide rail platform 10 is fixed with leg 11.
Be fixed with positional cylinder 12 on the said guide rail platform 10, the piston of positional cylinder is facing to pulley 6.
Said People's Bank of China platform ladder 13 1 ends are fixed on the workbench, and the other end places on the ground.
Said pouring robot 1 is six pouring robots, and motor 8 also can drive gear wheel 7 through gear-box and rotate.
Operation principle: motor 8 drives gear wheel 7 and rotates; Because gear wheel 7 is the bottoms that are fixed on brace table 4, workbench 2 rotates together like this, when whenever turning to a casting unit 3; PLC switch board (not shown) lets motor 8 stop this work; The piston of positional cylinder 12 is in the presence of pulley 6, and compressed oil cylinder 32 will be poured into a mould counterdie 37 and close with cast patrix 36 and close, and pouring robot 1 is got melt mould is poured into a mould from melting furnace.
Limit cast, the slow rotary die in rotary oil cylinder 33 limits makes its better crystallinity degree, and water-cooling channel 361 carries out water-cooled simultaneously, and electric heating tube 362 heats, the intensity of the product of guaranteeing to pour into a mould out.
After the work of a casting unit 3 was accomplished, the piston of PLC switch board indication positional cylinder 12 folded, and motor 8 is started working; So circulation; Constantly realize the cast of each casting unit 3, behind the casting complete, the casting unit of having poured into a mould 3 is through the water-cooled and the heating of appropriate time; Send instruction unpack cast counterdie 37 and cast patrix 36 by the PLC switch board, just can get with foundry goods.
