Intelligent aluminum alloy hub low-pressure casting device with speed regulation function

Abstract

The invention relates to an intelligent aluminum alloy hub low-pressure casting device with a speed regulation function. The intelligent aluminum alloy hub low-pressure casting device comprises an airinlet pipe, a crucible, a lifting mechanism, a casting mechanism and a liquid lifting pipe; a plurality of speed regulation mechanisms are arranged in the gas inlet pipe; the speed regulation mechanism comprises a translation assembly, a translation block, a speed regulation plate and a speed regulation assembly; the speed regulation assembly comprises a pressure plate, a spring, a speed regulation rod and two limiting units, the casting mechanism comprises a first motor, a first driving shaft, an upper mold, a lower mold and at least two connecting assemblies, the intelligent aluminum alloyhub low-pressure casting device with the speed regulation function is used for controlling the flow speed of air through the speed regulation mechanism, and then the flow of the air is adjusted, so that the air pressure in the crucible is stably increased, the use amount of the molten aluminum is conveniently controlled accurately, and the quality of the hub forming is improved, moreover, the upper die and the lower die are driven to rotate through a casting mechanism, so that the flowing of molten aluminum is enhanced, so that the molten aluminum is uniformly distributed between the upper mold and the lower mold, and the quality of hub forming and the practicability of device are further improved.

Description

technical field [0001] The invention relates to the field of wheel hub casting equipment, in particular to an intelligent aluminum alloy wheel hub low-pressure casting device with a speed regulating function. Background technique [0002] The wheel hub is also called the rim, the wheel, and the tire bell. It is a barrel-shaped, center-mounted metal part that supports the tire on the inner profile of the tire. There are many types of hubs according to diameter, width, molding method and material. In the process of manufacturing wheel hubs, two production methods, casting and forging, are mostly used, and the casting methods are divided into two types: gravity casting and low-pressure casting. Among them, low-pressure casting has become the most widely used casting due to its low cost and fast forming. Molding.

Problems solved by technology

[0003] When low-pressure casting is performed, compressed air usually enters the crucible from the intake pipe, which increases the air pressure in the crucible, forcing the molten aluminum inside the crucible to rise along the riser and enter the cavity of the mold. As time goes by, the molten aluminum It will fill the cavity, and then enter the pressure holding stage, and then complete the casting, but in the actual casting process, due to the inability to effectively control the flow rate of compressed air, the air pressure control in the crucible is unstable, resulting in the inability to effectively control the rise of the molten aluminum. Affect the quality of castings, not only that, after the aluminum liquid enters the mold cavity, due to the certain viscosity of the aluminum liquid, the aluminum liquid is unevenly distributed inside the mold, which in turn affects the quality of the wheel hub molding and reduces the existing low-pressure casting.
