ABSTRACT:
A mold box carries a removable pallet and is supported for tilting movement between a generally vertical filling position and a generally horizontal stripping position. In the filling position, the mold box receives a self-hardening material such as concrete to form a molded article. In the stripping position, the pallet and the molded article are pulled from the mold box onto a horizontal platform by a pulling member guided along the platform and connected to a fluid cylinder mounted on the platform. The pulling member connects with an arm member disposed within the mold box under the pallet when the mold box moves to its stripping position. The mold box is also disclosed with a plurality of parallel spaced core members, and the upper or outer ends of the core members are supported by pivotally retractable core support members.
