Problems solved by technology

[0004] The present invention is aimed at the processes of investment casting, precision casting, silica sol casting and processing of raw material rusted steel pipes and stainless steel rods in the prior art. The cost is high, the environment is polluted, the processing technology is complicated, it cannot be integrally formed, the appearance is not beautiful, and a large amount of steel is required. The purpose is to provide a coated sand casting process for stainless steel faucets. The use of coated sand cores can make stainless steel faucets integrally formed, reducing the production cost of stainless steel faucets by more than 30%. Shorten the solution by more than half

Embodiment 1

[0025] A coated sand casting process for a stainless steel faucet, which consists of the following steps in sequence,

[0026] A. Simulation of casting casting and cooling and solidification process: the mold temperature field test and simulation of the casting and solidification process are carried out by computer, and the thermal physical parameters of the mold are tested and measured;

[0027] B. Make the 3D drawing of the product: According to the product requirements, use Pro / E or UG 3D design software to make the 3D drawing of the product according to the simulation process, adopt the bottom casting casting design, that is, the casting port is set at the bottom of the product, so that the sand inside the product The gas produced after the core is heated slowly blows out, thereby improving the yield of the product; in this embodiment, Pro / E three-dimensional design software is used;

[0028] C. Prepare the mold: prepare the inner core mold and outer shell mold according t...

Abstract

The invention belongs to the technical field of casting techniques, and relates to a stainless steel water faucet casting process, in particular to a stainless steel water faucet sand-coating casting process. The stainless steel water faucet sand-coating casting process sequentially comprises the following steps of: A. simulating a cast-casting, cooling and solidifying process; B. drawing a three-dimensional map of a product; C. preparing a mould; D. performing numerical control and calibration; E. assembling the mould; F. manufacturing a sand core, G. casting and shaping; and H. clearing up. By the stainless steel water faucet sand-coating casting process, a solution is provided, so that a stainless steel water faucet can be integrally moulded by using a sand-coating core, as a result, the production cost of the stainless steel water faucet is reduced by more than 30%, and the delivery cycle is shortened by more than half.

Description

technical field [0001] The invention belongs to the technical field of casting technology, and relates to a casting process of a stainless steel faucet, in particular to a casting process of coated sand for a stainless steel faucet. Background technique [0002] Stainless steel faucets are widely used in public places such as homes, hotels, and hospitals because they are safe, lead-free, corrosion-free, and exudate, and will not cause secondary pollution to water quality. Now the faucets on the market are basically made of copper and zinc alloy materials, which will cause secondary pollution of water quality. After a long time of use, the electroplating layer will fall off or develop copper rust. Lead and copper rust will pollute tap water sources and damage people's health, while stainless steel The faucet does not need electroplating, and the manufacturing process will not pollute the environment, keep the water quality pure and hygienic, and will not need to be replaced f...
