Embodiment Construction

[0038] See figure 1 Shown: Magnesium alloy wheel mold, used for die-casting magnesium alloy wheels. The magnesium alloy wheels include rims

[0039] 20. The downwardly projected area of ​​the outer edge of the rim 20 is S2.

[0040] See figure 2 As shown, the magnesium alloy wheel mold includes a body 10, the body 10 is provided with an ingate 11 and a cavity for forming a magnesium alloy wheel, and the ingate 11 has a cross-sectional area S1. In the present invention, the cross section of the gate 11

[0041] The relationship between the surface area S1 and the downwardly projected area S2 of the outer edge of the rim 20 is: 5‰S2≦S1≦10‰S2. Optimally, the relationship between the cross-sectional area S1 of the ingate 11 and the downwardly projected area S2 of the outer edge of the rim 20 is: 6‰S2≦S1≦8‰S2. Optimally, for a common 15-inch magnesium alloy wheel hub, the relationship between the cross-sectional area S1 of the ingate 11 and the downwardly projected a...

Abstract

The invention discloses a magnesium alloy hub die used for die-casting forming of a magnesium alloy hub. The magnesium alloy hub comprises a rim. The area of the downward projection of the outer edge of the rim is S2. The magnesium alloy hub die comprises a body provided with an inner sprue and a cavity used for forming the magnesium alloy hub. The area of the cross section of the inner sprue is S1, and the relation between the area S1 of the cross section of the inner sprue and the area S2 of the downward projection of the outer edge of the rim is 0.5% S2<=S1<=1% S2. The magnesium alloy hub die has the beneficial effect that a high-density casting can be cast.

Description

technical field [0001] The invention relates to the technical field of auto parts preparation, in particular to a magnesium alloy wheel hub mold. Background technique [0002] With the prominent energy shortage and environmental pollution problems, lightweight has become the trend of vehicle development. another [0003] On the one hand, as the demand for vehicles continues to increase, the metal materials such as steel and aluminum required for vehicles are also increasing day by day. According to statistics, the reserves of resources such as iron and aluminum in the world are only enough for 100 to 300 years. In my country, iron The reserves are not abundant, and the quality of bauxite is not high, so it is urgent to seek a new alternative material. [0004] Magnesium alloy, the lightest metal structural material known, has gradually become the lightest vehicle due to its many advantages. [0005] The main research object in development. Compared with steel and aluminum...
