| 56 | Method for Squeezing Foundry Sand, a Match Plate, and an Upper and a Lower Flask | US11587633 | 2005-04-27 | US20070227684A1 | 2007-10-04 | Minoru Hirata; Tokiya Terabe; Koichi Sakaguchi |
| In a conventional apparatus for molding molds, foundry sand is filled in an upper and a lower molding space defined by a match plate, an upper and a lower flask, and an upper and a lower squeeze plate, and then the foundry sand is squeezed by causing the upper and the lower squeeze plate to further approach each other. However, the hardness and strength near the inner surface that corresponds to the match plate, of an upper and a lower mold made by the conventional apparatus, are not high enough. To solve this problem, in this invention the following method is applied: a method for squeezing foundry sand filled in an upper and a lower molding space, comprising: a step to squeeze the foundry sand by causing the upper and the lower squeeze plate to further approach each other, and a step to squeeze it by causing the pattern portions of the match plate to move to each of the upper and the lower squeeze plate. | ||||||
