Apparatus for actuating inner and outer forms of a concrete pipe forming mold

摘要

A concrete pipe molding apparatus includes inner and outer mold forms defining an annular chamber therebetween. The outer form comprises first and second form sections. These sections are completely separable along two longitudinal gates. A clamp assembly is provided at each gate for releasably securing the outer form sections together. The clamp comprises an eccentric disc mounted for rotation on the first mold section. A locking arm is rotatably mounted on the eccentric disc. The locking arm includes a clamping hook which is releasably engageable with a flange on the second form section. A motor is operably connected to the eccentric disc for rotating the hook away from and toward the flange. The inner form comprises a pair of form portions that are separable along a gate. A mechanism is provided for collapsing the inner form to permit removal thereof from a hardened pipe.
