Resin sand casting process

Abstract

The present invention discloses a resin sand casting process, the resin sand casting process is characterized by comprising the following steps, to be more specific, 1) preparing, to be more specific, whether waste sand in a molding machine is cleaned up is checked, a switch is clicked, whether equipment operation is abnormal is checked, and whether each equipment is abnormal is checked according to the process opposite to the technical process; 2) distributing boxes; 3) molding; 4) drawing from a mold; 5) spraying paint and flow coating; 6) setting a core and closing a box; and 7) casting and knocking the box, to be more specific, a 0.5T casting ladle is used for casting, a thick-walled casting is casted with a first packet of molten iron, casting time and a gap between the sand boxes are grasped, when in casting, a wooden stick is used for igniting exhaust at a gas outlet and a riser, 12 hours after the casting, the box is opened, when the box is knocked, a special casting riser is left after shot blasting and sand removal, and after 1 / 3 of the root of the riser is rubbed off by a grinding wheel plate, the special casting riser is knocked down, in the manner, peeling off can be prevented, and when a casting water nozzle is cleaned up, the casting is not allowed to be damaged when the casting is provided with burrs. The casting process is simple, many repetitive processes are eliminated, and work efficiency is improved.

Description

technical field [0001] The invention relates to a resin sand casting process. Background technique [0002] At present, the resin sand casting process is relatively complicated, and there is no unified specification and standard, resulting in uneven modeling quality, and many repeated processes also make the production efficiency low, increase the labor burden of workers, and at the same time make the market competitiveness of the product not tall. For some operators who have just entered the industry, there is no clear method and process, resulting in frequent mistakes and omissions during operation, and may even cause serious consequences. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a resin sand casting process, which is simple, eliminates many repetitive procedures, and improves work efficiency. [0004] In order to achieve the above purpose, the p...
