Pure-aluminium die casting equipment and pure-aluminium die casting technology

Abstract

The invention is applicable to the technical field of pure-aluminium die casting, and discloses pure-aluminium die casting equipment and a pure-aluminium die casting technology. The pure-aluminium die casting equipment comprises a die-casting machine connected with a die-casting die; the die-casting machine comprises a material feeding barrel; the pure-aluminium die casting equipment further comprises a central melting furnace used for heating and melting an aluminium block, a heat preserving furnace used for performing heat preservation on molten aluminium, a molten aluminium feeding device used for conveying the molten aluminium into the material feeding barrel and a press-shooting device used for press-shooting the molten aluminium from the material feeding barrel to the die cavity of the die casting die; an ejecting device used for ejecting a formed product from the die cavity is arranged on one side of the die casting die; and the press-shooting device is provided with an electro-hydraulic proportional throttle valve with valve core position feedback. The above pure-aluminium die casting equipment is adopted in the pure-aluminium die casting technology. By adopting the pure-aluminium die casting equipment and the pure-aluminium die casting technology provided by the invention, the production qualification rate is high; the cost is low; and the requirement of markets on volume production of pure-aluminium parts is met.

Description

technical field [0001] The invention belongs to the technical field of pure aluminum die-casting, and in particular relates to pure aluminum die-casting equipment and a pure aluminum die-casting process. Background technique [0002] Aluminum alloy die-casting parts are widely used in the market, such as various hardware parts, structural parts, etc., but the current aluminum alloy die-casting parts generally have problems such as silicon content, poor heat dissipation, and the surface cannot be anodized. Only spray paint and electroplating can be used And other processes, which lead to not beautiful appearance, poor corrosion resistance, poor wear resistance, easy peeling and discoloration. Pure aluminum products can solve the above problems. After anodic oxidation treatment, the pure aluminum products after die-casting have good corrosion resistance, good electrical and thermal conductivity, less impurities, rich colors after surface treatment, and meet environmental prote...

AI Technical Summary

Problems solved by technology

[0003] However, the pure aluminum die-casting technology currently on the market is not mature enough. This is because the melting point of pure aluminum is higher than that of aluminum alloy, the surface texture is soft, the fluidity is poor, it is easy to stick to the mold, easy to crack, easy to bruise, and there is a low production pass rate. , high production costs, etc.
