Abstract
The invention relates to an integrated induction heating metal melting and fluidizing device of a die-casting machine. The integrated induction heating metal melting and fluidizing device of the die-casting machine is composed of a pressing jetting part and an induction heating part. The pressing jetting part comprises a material pipe, a pressing jetting piston and a pressing jetting push rod. The induction heating part comprises a heating pipe, an induction coil, an insulation thermal insulating layer and an external electric frequency induction power source. The electric frequency induction power source is connected with the induction coil, the heating pipe is arranged on the material pipe in a sleeving mode in the outer diameter direction, and the induction coil and the insulation thermal insulating layer are arranged on the heating pipe in the outer diameter direction in sequence. The electric frequency induction power source is started, a strong magnetic bundle with polarities changing instantly is generated in the induction coil, eddy current is generated inside the heating pipe, the temperature rises rapidly, metal materials are hot melted, and the pressing jetting piston extrudes the hot melted metal materials forwards to be jet into a fixed die from the material pipe in a pressing mode. The induction current is used for heating the metal materials, efficiency is high, the speed is high, and energy consumption is little. Metal cannot be oxidized in the sealed high-temperature environment, the quality of products is improved, the production cost is lowered, and the work environment is improved.

Technical field
The present invention relates to fluidic device and the metal molten device of die casting machine, particularly a kind of die casting machine integration eddy-current heating metal molten fluidic device.
Background technology
The fluidic device of current die casting machine and metal molten device are two independently structures.Substantially be all first metal is put into metal molten device, controlling melt temperature is kirsite 380-420 DEG C, aluminium alloy 610 DEG C-710 DEG C, magnesium alloy 800-850 DEG C, copper alloy 1000-1100 DEG C, liquid metal enters in the barrel of fluidic device, by the piston of injection device the metal of melting being penetrated compresses into into die cavity, filling speed is 6 meter per second-20 meter per seconds, and injection power is 600-800KN, and liquid metal fills up whole mold cavity, and to complete compression casting shaping.The shortcoming of above-mentioned two independently die casting machine fluidic device and metal molten apparatus structures is: metal molten device adopts that the time of pincers pot deposite metal is long, power consumption is large, cost is high, and metal is easily oxidized in hot environment, affect the quality of product, the work situation of workman is poor.
Summary of the invention
The object of the invention is the shortcoming existed for above-mentioned die casting machine fluidic device and metal molten device, develop a kind of die casting machine integration eddy-current heating metal molten fluidic device.Increase induced-current generator at the external diameter of die casting machine material pipe, die casting machine fluidic device and metal molten device are integrated.Induced-current is high to the metal material efficiency of heating surface, speed fast, and power consumption is few.Metal can not be oxidized in the hot environment of sealing, improves the quality of product, reduces production cost, improve working environment.
The object of the present invention is achieved like this:
Die casting machine integration eddy-current heating metal molten fluidic device is made up of injection portion and eddy-current heating portion.
