Method for solving distortion generated in die-casting piece

Abstract

The invention relates to an aluminum alloy die-casting improving method, in particular to a method which is suitable for solving distortion generated in a die-casting piece. By adopting the following methods: casting piece structure is improved, the best mould opening time is determined, casting obliquity is increased, coating material is used correctly, ejector rods and the quantity of the ejector rod are reasonably arranged, the generation of distortion defect of the aluminum alloy die-casting piece is effectively improved.

Description

Technical field [0001] The invention relates to an aluminum alloy die-casting process method, in particular to a method suitable for solving the deformation of die-casting parts. Background technique [0002] During the die-casting production process, the overall deformation of the die-casting part does not conform to the drawing. Also known as twisting, warping. The existence of these defects will directly affect the quality of die castings. The main reasons for this defect are as follows: First, the structural design of castings is poor. It causes uneven shrinkage; second, the mold is opened too early, and the rigidity of the casting is not enough; third, the casting slope is too small or there is sticking to the mold; fourth, the operation of taking and placing the casting is improper; fifth, the stacking is unreasonable or the method of removing the gate is improper; Sixth, the position of the ejector pin is improper or the casting is deflected during the ejection proc...
