Hardware casting process

Abstract

The invention discloses a hardware casting process. The process comprises the following steps of wax treatment, wax injection, flash trimming away, tree assembling, tree cleaning, shell making, dewaxing, roasting and pouring, vibrating shell, cutting, sand clearing, and sprue gate grinding; wherein A, wax treatment comprises the following steps that equipment and temperature control instrument arechecked whether in a normal working state; and old wax liquid separated from a dewaxing kettle is discharged into a filter tank for filtration and dehydration. The process comprises the following steps of wax treatment, wax injection, flash trimming away, tree assembling, tree cleaning, shell making, dewaxing, roasting and pouring, vibrating shell, cutting, sand clearing, and sprue gate grinding,when the hardware is subjected to casting processing, the operation is strictly performed according to the process standard, the technological operation process is simple, the time is short, the hardware can be subjected to large-batch processing and production, so that the economic benefit is further improved, and meanwhile, the problem that during the process of casting, the process is complex,the operation time is long, so that the processing efficiency of the hardware is influenced, and the hardware is inconvenient to produce in a large scale is solved.

Description

technical field [0001] The invention relates to the technical field of casting processing, in particular to a hardware casting process. Background technique [0002] Hardware is widely used in daily life. According to different functions, its shape is also various; in the process of hardware processing, it is often necessary to process strip-shaped hardware into ring-shaped hardware. The traditional coiling process is to The bar-shaped hardware is placed between two round rollers. By turning the handle on one of the round rollers, the bar-shaped hardware is bent into a ring-shaped hardware. When casting, the smelted liquid metal is poured, shot, Suction or other casting methods are poured into the pre-prepared mold, and after cooling, grinding and other subsequent processing methods, the obtained objects with a certain shape, size and performance often suffer from complex processes and long operation time during casting processing. , while affecting the processing efficienc...
