Abstract

The invention relates to a radiator manufacturing technology, in particular to a production technology for a cast iron, magnesium alloy and aluminum alloy radiator. The production technology for the cast iron, magnesium alloy and aluminum alloy radiator solves the technical problems existing when a heating pipe is made of cast iron and magnesium alloy or aluminum alloy. According to the production technology, a spheroidal graphite cast iron I-shaped core tube and magnesium alloy are used as raw materials, and a core tube die, a casting die and a cold chamber die casting machine are used as devices; according to the casting die, the core tube structure is in an I shape, and the core tube is integrally cast through the core tube die; the I-shaped core tube cannot be manufactured in a welded mode, the cold chamber die casting machine is started, powering on is conducted, the magnesium alloy is heated into molten magnesium alloy, the I-shaped core tube is placed in a die cavity, after the die is closed, casting continues to be conducted, the molten magnesium alloy is pushed and injected into the die cavity through high pressure, the molten magnesium alloy is made to be attached to the outer surface of the core tube, the pressure ranges from 130 mpa to 150 mpa, the pressure is kept for 15-20 seconds, after pressure release, cooling is conducted for 3-5 seconds, a machine is started to open the die, a product is ejected, the product is taken out and completely naturally cooled, and the surface of the product is treated finally. According to the production technology, through one-off die-casting formation, the cast iron and the magnesium alloy are perfectly fused, the cast iron is used as water flow channel and resistant to corrosion, and the magnesium alloy is light and has excellent radiating performance.

Description

technical field [0001] The invention relates to a radiator preparation process, in particular to a production process of cast iron, magnesium and aluminum alloy radiators. Background technique [0002] Traditionally used cast iron radiators have the advantages of corrosion resistance, long service life, simple manufacturing process, and low production cost. It is widely used in the radiator manufacturing industry. However, its weight is too large and its appearance is rough, which affects people's further needs. The radiator made of all aluminum alloy or magnesium alloy is light in weight and beautiful in appearance, but its weakness is poor corrosion resistance, short service life and high cost. [0003] Therefore, we use the advantages of cast iron radiators such as corrosion resistance, long service life, simple manufacturing process, and low production cost, combined with the advantages of light weight and beautiful effects of aluminum alloy and magnesium alloy radiato...
