Aluminium wheel casting plant for automobile

Abstract

The invention relates to an aluminum wheel casting device for automobiles, which is used for die-casting of aluminum wheels with good quality through improvement of working conditions and structure of aluminum wheels. The casting device has the advantages of improving work efficiency and satisfaction degree of the quality of the die-casting aluminum wheels, minimizing the power consumption of a heater by improving the structure of the aluminum wheel casting device, improving productivity of products, preventing burn accident of caused by direct contact with a high temperature die base in the prior art, overcoming the casting defects of the die-casting wheels caused by overheat among the side dies by keeping horizontal force and bearing force, and improving the satisfaction degree of the die-casting wheels cast through aluminum molten.

Description

technical field [0001] The present invention relates to an aluminum wheel casting device for automobiles, and more particularly, it is capable of molding aluminum wheels of good quality by improving the working environment and improving the structure of the aluminum wheels. Background technique [0002] In general, an aluminum wheel casting apparatus for automobiles is an apparatus for casting aluminum wheels by casting the aluminum by using compressed air generated by a compressor after injecting molten aluminum formed by a The melt is forcibly injected into the mold base located above the isothermal furnace, and when the internal temperature of the isothermal furnace is maintained at a high temperature exceeding about 750° C., good quality aluminum wheels can be obtained. [0003] Here, the mold base includes upper and bottom molds and a plurality of horizontally moving side molds. [0004] However, there is such a problem in the prior art that the upper mold and the bott...

Problems solved by technology

[0004] However, there is such a problem in the prior art that the upper mold and the bottom mold are not properly interlocked, and because the upper mold will rise together with the upper mold when it is pressed against the bottom mold after pouring molten aluminum into the bottom mold. The high movable plate will expand horizontally due to heating and the guides used to guide the lifting movement of the upper mold will bend, so the quality of the molded wheel will decrease

[0005] Also, in the prior art, the compressed air produced by the compressor includes a certain amount of water vapor, and its other problem is that the power consumption is very high, because the upper temperature of the constant heat welding furnace is due to the injection of compressed air into the constant heat welding. lowered inside the furnace

[0006] Also, there is another problem in the prior art that the productivity of the product will decrease because it has such a structural disadvantage that when the mold base including the upper, bottom and side molds is rotated and placed in place on the upper , the staff will tighten and loosen the hook bolts every time, and when the staff performs high temperature treatment on the mold base, accidents such as burns may occur

[0007] Also, in the prior art, it is impossible to prevent the outflow of molten aluminum between the tube and the injection port of the bottom side mold, because when the molten aluminum is injected into the bottom mold through the tube, the gasket arranged on the tube is used To prevent the outflow of molten aluminum, but the structural disadvantage of the liner is that it will produce some wear after a certain period of use

[0008] Also, there is such a problem in the prior art that when the compressed air of the upper mold is generated, the load and pressure of the constant heat welding furnace cannot be distributed by the buffer spring, because the buffer of the constant heat welding furnace injected with molten aluminum The effect is only achieved by the buffer spring, and because the horizontal force and supporting force of the constant heat welding furnace cannot be maintained reliably, the processing of the mold casting will be deteriorated

[0009] Also, in the prior art, work efficiency is reduced because the take-out position of the molded wheel is always fixed, and equipment for taking out the molded wheel has not been equipped, and when the inspection work is performed, the worker must accompany the position Variety

[0010] Also, there is such a problem in the prior art that there is a defect in molding the wheel because when the molten aluminum is poured into the bottom mold, a certain temperature is applied to the plurality of side molds located around the bottom mold, but this When the applied temperature is uncertain, it is easy to cause overheating between the molds

[0011] Also, in the prior art there is such a structural disadvantage that the quality of the molded wheel is greatly reduced, because when the molten aluminum is injected into the bottom mould, the temperature of the tube has to be maintained reliably, but such equipment is not equipped with the the tube
