Method for casting motorcycle parts by use of low-pressure casting process

Abstract

The invention discloses a method for casting motorcycle parts by use of the low-pressure casting process. The method has the characteristics of short production period, short machining process flow, low equipment input, high yield, low production cost, small tool loss, high utilization ratio of raw materials, good production quality stability, and the like. Three-dimensional modeling software is utilized to perform three-dimensional modeling on motorcycle parts needing to be cast, a metal-type low-pressure casting process is used together to determine casting process parameters, and three-dimensional blank casting is finished according to the casting process parameters including alloy material chemical components, a gating system, machining allowance and a parting surface. The alloy material chemical components comprise the following ingredients by weight percent: less than or equal to 0.5% of C, less than or equal to 1.2-1.8% of Cu, less than or equal to 1.8-2.4% of Mn, less than or equal to 0.5-.8% of Si, less than or equal to 1.2-1.5% of Zn, less than or equal to 0.2-0.5% of Ni, less than or equal to 1-1.8% of Mg, less than or equal to 2-6% of AL, less than or equal to 0.3-0.8% of Ti, and the balance of Fe. The modeling of a casting mold is designed, and the designed modeling of the casting mold is used for manufacturing a metal-type low-pressure mold.

Description

technical field [0001] The invention relates to the fields of casting technology and the like, specifically, it is a method for casting motorcycle accessories by using a low-pressure casting process. Background technique [0002] Casting - smelting metal, making casting molds, pouring molten metal into casting molds, and obtaining metal parts blanks with certain shape, size and performance after solidification. [0003] Casting is the process of smelting metal into a liquid that meets certain requirements and pouring it into a mold, cooling and solidifying, and cleaning to obtain a casting with a predetermined shape, size and performance. Because the casting blank is almost shaped, the purpose of free machining or a small amount of machining reduces the cost and reduces the production time to a certain extent. Casting is one of the basic processes of the modern device manufacturing industry. [0004] Casting is a kind of metal thermal processing technology mastered by human...

Problems solved by technology

[0035] Disadvantages: 1. The mechanical properties are not as good as forgings, such as coarse structure and many defects;

[0036] 2. In sand casting, single piece and small batch production, the labor intensity of workers is high;

[0037] 3. The quality of castings is unstable, there are many processes, the influencing factors are complex, and many defects are prone to occur

[0047] Casting production has different characteristics from other processes, mainly because it has wide adaptability, requires more materials and equipment, and pollutes the environment.
