ABSTRACT:
A no bake blower for making sand cores.
A blow head has a blow plate detachably mounted at the lower end of the blow head and adapted to be moved vertically away from the blow head. The blow head is movable horizontally with respect to the blow plate and in so doing scrapes residual sand off the blow plate.
A blow plate cleaning mechanism is carried by the blow head into vertical alignment with the blow plate after the blow head has been horizontally moved. The cleaning mechanism has vertical rods which pass through the blow holes in the blow plate to remove residual sand from them.
