The mold includes a first mold block having a first contact surface and a first shear surface, a second mold block having a second contact surface and an insert seating surface, and at least one removable insert having a second shear surface and positionable along the insert seating surface. The first mold block is separable from and engageable with the second mold block between open and closed positions of the mold. The mold is moved between open and closed positions by the movement of at least one of the mold blocks along a path of travel. When the mold is moved from an open to a closed position, the first shear surface and the second shear surface form an interference fit.
