Abstract

PURPOSE: To press the sand in a molding flask charged with sand from a hopper to a pattern, mold upper and lower molds alternately and improve molding efficiency by moving the molding flask upward to the upper pattern.
CONSTITUTION: A molding flask 11 is moved upward to right under a hopper 23, and a squeeze table 10 is moved upward by a cylinder 6, thereby airtightly closing the under surface of the flask 11. Next, the molding sand in the hopper 23 is charged into the flask 11 and the flask 11 is moved downward together with the table 10 down to the position below a top part pattern plate 15. Thence, a cylinder 20 is operated to advance the plate 15 to right above the table 10 and again the table 10 and the flask 11 are moved upward until the top surface of the flask 11 abuts on the under surface of the plate 15, when compressed air is supplied through a supply port 7 into the flask 11, thereby blowing and gathering the sand upward and hardening the same. Next, when the flask 11 is lowered together the table 10 down to the home position, the top part in the flask 11 is pushed upward by the table 10. It is next pushed out into a conveyance path 27 by a cylinder 24. In this way, the drag is molded in a similar manner.
