FRAME FOR MOLDING MACHINE AND METHOD OF MOLDING USING THE FRAME

摘要

Frames for a molding machine for holding foundry sand therein and preventing the deformation and mismatch of molds. Each of the upper frame (104) and the lower frame (105) comprises a body having at least one supply port (101) specifying an opening for molding the molds and supplying the foundry sand into the opening. A pair of flanges (102) positioned oppositely to each other through the opening and having through holes are extended from the body to the outside. A frame member comprises an engagement member engageable with an actuator so that a force from the actuator on the outside of the frame can be transmitted to the frame. The upper frame (104) and the lower frame (105) positioned oppositely to each other through a pattern base board (107) are integrally connected to each other by fitting a pair of connection levers (106) into these through holes to form a frame unit.
