Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy die-casting, in particular to a die-casting mold for aluminum alloy parts. Background Art

[0002] Aluminum alloy die-casting products are mainly used in electronics, automobiles, motors, home appliances and some communications industries. Some high-performance, high-precision, high-toughness high-quality aluminum alloy products are also used in large aircraft, ships and other industries with relatively high requirements. The main use is still in the parts of some equipment.

[0003] During the die-casting process, the molten metal fills the cavity at high speed and high pressure, which easily draws in gas and causes pores inside the casting. The areas where the wall thickness of the aluminum alloy die-casting mold is too thick, especially those far away from the gate, need to be solved through product design or through special processes or other auxiliary equipment. The cost is high and the process control is difficult. Therefore, aluminum alloy inserts are generally added to the problem areas to remove the pores, because the space at the wall thickness position is reduced by placing the inserts, thereby reducing the pores during processing. However, these inserts need to be pre-embedded in the die-casting mold and then cast together with the die-casting. However, the traditional method of manual addition is too close to the die-casting machine, and the high-temperature aluminum liquid will affect the workers and the production efficiency will also be affected.

[0004] Therefore, the utility model provides a die-casting die for an aluminum alloy part to solve the above-mentioned problem. Utility Model Content
