Abstract
The invention discloses a scraper plate molding technology of lipid hardening sodium silicate self-hardening sand. A sand box (5) is placed on the ground surface; an erect scraper plate shaft (6) is arranged in the middle of the sand box (5); the lipid hardening sodium silicate self-hardening sand is filled in the sand box (5), and a plane (7) is scraped; after the lipid hardening sodium silicate self-hardening sand is hardened, a metal core box (1) is placed on the plane and is rectified by taking a scraper plate shaft as a circle center; then an appearance scraper plate (2) is placed on the metal core box; the center of the appearance scraper plate is sleeved on the scraper plate shaft; the lipid hardening sodium silicate self-hardening sand is filled fully into a cast inner cavity (3); the appearance scraper plate is rotated along the scraper plate shaft; and an inner surface (4) of a casting is scraped by the appearance scraper plate, thereby obtaining the required casting inner surface shape, and completing the molding operation. According to the scraper plate molding technology disclosed by the invention, the appropriate metal core box is manufactured according to the height required by the casting; the metal core box is placed into mold sand; the inner surface shape of the casting is scraped and manufactured by the scraper plate; the sand collapse of the lipid hardening sodium silicate self-hardening sand can be prevented effectively; and the scraper plate molding technology of the lipid hardening sodium silicate self-hardening sand is wide to apply, and is convenient to operate.
Description
Technical field
The invention belongs to the molding sand casting technology field.
Background technology
Fat Hardening Sodium Silicate self-hardening sand molding is that a kind of production cost is low, the casting quality that obtains of casting is high, good work environment, old sand can realize the good casting technique that dry back is used, and is widely used in actual production.Fat Hardening Sodium Silicate self-hardening sand adopts modified water glass, and its sclerosis mode is to use alicyclic organic and curing agent sclerosis, and good collapsibility and reuse are arranged, and the Performance Ratio of molding sand is better.And conventional self-setting silicate process adopts light water glass, and the sclerosis mode is carbon dioxide hardening and heat hardening, and collapsibility and reuse are poor, and the performance of molding sand is also poor.Fat Hardening Sodium Silicate self-hardening sand good fluidity, but poor plasticity causes in actual production, on short transverse, molding sand the sand that can collapse before that do not harden, and while using strickle moulding, can only scrape the molding sand of 50～60mm height,, for the larger foundry goods of the degree of depth sand that easily collapses, be difficult to the production of foundry goods.
Summary of the invention
The deficiency that purpose of the present invention exists in actual production technique in order to solve above-mentioned fat Hardening Sodium Silicate self-hardening sand just, provide a kind of in the larger foundry goods of the casting size degree of depth or molding sand height casting mold be difficult for the collapsing strickle moulding technique of fat Hardening Sodium Silicate self-hardening sand of sand when larger.
Purpose of the present invention is achieved through the following technical solutions.
a kind of strickle moulding technique on fat Hardening Sodium Silicate self-hardening sand, sandbox is put on the ground, be provided with upright scraper shaft in the middle of sandbox, pack into fat Hardening Sodium Silicate self-hardening sand in sandbox and scrape a plane, after the sclerosis of fat Hardening Sodium Silicate self-hardening sand, take scraper shaft as the center of circle, master pattern is placed in the plane and proofreaied and correct, then the profile scraper plate is placed on above master pattern, the center of profile scraper plate is contained on scraper shaft, fat Hardening Sodium Silicate self-hardening sand is filled up the casting mold internal cavity, the profile scraper plate is rotated along scraper shaft, scrape the foundry goods inner surface with the profile scraper plate, obtain needed foundry goods inner surface configuration, complete moulding work.
The present invention manufactures suitable master pattern according to the height that foundry goods requires, and master pattern is put into molding sand, uses scraper plate to scrape the inner surface configuration of making foundry goods, can effectively prevent the fat Hardening Sodium Silicate self-hardening sand sand that collapses.The present invention can effectively solve the sand problem of collapsing of fat Hardening Sodium Silicate self-hardening sand, and is applied widely, convenient operation.
Description of drawings
Fig. 1 is process schematic representation of the present invention.
The specific embodiment
As shown in Figure 1,, according to the profile of foundry goods, make the master pattern 1 that is fit to.Select suitable sandbox 5, put on the ground, the good level in school.Be provided with upright scraper shaft 6 in sandbox.pack into fat Hardening Sodium Silicate self-hardening sand in sandbox and scrape a plane 7, after the sclerosis of fat Hardening Sodium Silicate self-hardening sand, take scraper shaft 6 as the center of circle, be placed on plane 7 circular metal core box 1 and the adjustment good position, then the profile scraper plate 2 of dome shape is placed on above master pattern 1, the center of profile scraper plate 2 is contained on scraper shaft 6, the position of the good profile scraper plate of adjustment, master pattern 1 is contacted with profile scraper plate 2 and position dimension accurate, at this moment, master pattern inside and top are cavitys, fill up casting mold internal cavity 3 from top with fat Hardening Sodium Silicate self-hardening sand, profile scraper plate 2 is rotated along scraper shaft 6, scrape foundry goods inner surface 4 with profile scraper plate 2, obtain needed foundry goods inner surface configuration, complete moulding work.
