Abstract

Core blowing machines comprise a mid-plate (2) between the blowing head (1) and the blowing plate (3), the MID-PLA (2) having holes (4) that whilst allowing the free passage of sand and its binder towards the blowing mouth (3) when the head (1) acts and blowing comes about, however prevent the passage of sand through the same simply due to gravity, specifically when the blowing plate is changed or replaced. The mid-plate (2) has hydraulic attachments (5) that are independent from the hydraulic attachments (6) of the blowing plate (3), so that when replacing the latter the mid-plate (2) shall remain duly fixed to the blowing head (1). It is thereby possible for the plate change to be far quicker, for the said plate to be hardly soiled and for the classic loss of sand during the change to be eliminated.
