Sand box molding process

Abstract

The invention discloses a sand box molding process. The sand box molding process comprises the following steps that 1, molding is conducted, specifically, (1) when molding is conducted through an iron sand box, the sand box is positioned through positioning pins and smoothly put onto a mold plate; (2) when molding is conducted, molding sand must be screened through a screen and then is added into the sand box; (3) air hole pricking is conducted, and not less than two air holes are pricked per 100*100 square millimeters; and (4) a layer of sand with the thickness being 10-20 mm is paved on the mold placing ground and scraped to be uniform through a sand scraping toothed plate, a lower leaf is smoothly put on the sand, and after loose face sand on the surface is blown off through a bellow, smooth box closing is conducted; and 2, box closing is conducted, specifically, (1) whether male pin bodies and female pin bodies of the sand box in each furnace are misplaced or not is checked to prevent mismatch; (2) a core needs to be carefully checked before core setting, and after core setting is conducted, the core is blown again through air; and (3) when box disengaging is conducted, the sand box needs to be lightly smashed to prevent mismatch and sand dropping, and if the sand box cannot be disengaged easily, the inner wall of the sand box is appropriately coated with a thin layer of release agent. According to the sand box molding process, the process is simple, a lot of repetitive processes are omitted, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a sand box molding process. Background technique [0002] At present, the sand box molding process is relatively complicated, and there is no unified specification and standard, resulting in uneven production sand box molding process, many repeated processes also make the production efficiency low, increase the labor burden of workers, and at the same time make the market of the product Not very competitive. 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 of the prior art, the technical problem to be solved by the present invention is to provide a sand box molding process, which is simple in process, eliminates many repetitive processes, and improves work efficiency. [0004] In order to achieve the above...
