Apparatus for producing molds |
摘要 |
The molding apparatus includes a table movable between an area where molding sand is fed and a mold-producing area for carrying a pattern plate on which a flask is mounted, a cylinder for vertically moving the table, a closing cover having an opening at the lower part thereof, the opening communicating with an upper opening of the flask. The closing cover has a stepped part such that the cross-sectional area of the lower part of the closing cover is smaller than that of the upper part thereof. At least one air-supply pipe communicates with the upper part of the closing cover and an air valve communicates with the air-supply pipe to introduce ambient air into the air-supply pipe. An opening is formed in an upper and side part of the closing cover for communicating with a vacuum source. A press plate is suspended in the closing cover for a vertical movement such that the press plate can be airtightly inserted into the small lower part of the closing cover.
