Description

Improvement of high-purity aluminum die-casting die

Technical Field

The utility model relates to the technical field of mold, specifically be a high-purity aluminum die casting die's improvement.

Background

Die casting is a metal casting process and is characterized in that high pressure is applied to molten metal by utilizing an inner cavity of a die. The mold is typically machined from a stronger alloy, a process somewhat similar to injection molding. Most die cast parts are iron-free, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. Depending on the type of die casting, either a cold chamber die casting machine or a hot chamber die casting machine may be used. In the current aluminum product industry, products subjected to anodic oxidation treatment have good market prospect due to the advantages of high-end atmosphere, strong metal texture, environmental protection, corrosion resistance and the like. However, deformed aluminum is manufactured by milling, extruding, forging, punching and milling assistance, and the manufacturing cost is very high. The deformed aluminum die-casting formation is influenced by multiple factors such as materials and dies, the end of the product is badly formed, the water wave is serious, the effect after anodic oxidation is not good, and the popularization is difficult.

Anodic aluminum ingot, it is high to smelt the temperature, and mobility is poor, and the shaping needs the pressure higher than ordinary aluminium, and the mould inner gate undersize receives to strike too big and leads to the sticking die, and aluminium purity is high, and the heat dissipation is fast, and runner, the undersize lead to the heat loss too big easily, lead to the terminal shaping difficulty of product, and aluminium liquid is terminal to the product, strikes the mould die cavity wall, forms the recoil, leads to terminal aluminium liquid to form the vortex, but the counter impact force is because of aluminium liquid heat loss, strength loss, causes the vortex.
