Automatic production line technology and equipment for low-pressure casting of aluminum alloy

Abstract

The invention belongs to the technical field of metal casting equipment, and particularly relates to full automatic continuous casting production equipment and technology for low-pressure casting of aluminum and aluminum alloy. The equipment consists of a smelting furnace (1), a low-pressure heat preserving furnace (2), a wheel type multi-platform casting machine (3), an automatic part-taking mechanical arm (4), an automatic dedusting-spraying-cooling three-in-one mechanical arm (5), an automatic conveyor and liquid level pressuring device (6), a temperature control cabinet (7) and a control panel (8). By adopting a numerical control multi-station and timing-sequence-sharing continuous casting technology, the raw material is fed into the smelting furnace, and is automatically transported into the heat preserving furnace after being smelted, and molten aluminum is injected into metal molds on the wheel type multi-platform casting machine under the control of the liquid level pressuring device, so that a product can be formed. A plurality of molds and corresponding mold disassembly / assembly mechanisms are arranged on the wheel type multi-platform casting machine, and the working procedures such as the casting, the shape keeping, the mold disassembling, the part taking, the cleaning-spraying-cooling, the mold assembling and the like in the process of the low-pressure casting can be completed on different stations at different times when the wheel type multi-platform casting machine rotates, so that the continuous and quantitative automatic production of the aluminum alloy cast parts can be realized.

Description

technical field [0001] The patent of the present invention belongs to the technical field of metal casting equipment, and in particular relates to the automatic continuous casting production equipment and process realized by low-pressure casting technology for aluminum and aluminum alloys. Background technique [0002] Low-pressure casting is a casting method between pressure casting and gravity casting. It has the following advantages: First, it has smooth metal liquid filling, which can avoid metal tumbling, impact and splashing, reduce oxidation slag inclusions, and improve casting quality. The second is that the metal fills the mold under pressure, and the fluidity increases, which is convenient for pouring complex thin-walled castings, so that the outline of the casting is clear; the third is that the casting crystallizes under pressure and can be fully fed, so the casting structure is compact 1. The mechanical properties are improved; the fourth is that the riser can b...
