Abstract
A system and method of separating a cast concrete product from a mold is provided. The system includes a rotating drum arrangement, a catch arm attached to rotate with the drum arrangement, and a mold having at least one cavity to form the concrete product. The mold includes a lead end opposite a trail end relative to a sequence of engagement by the rotating drum arrangement. The mold further includes a grab bar inserted through the mold. The rotating catch arm is configured capture the grab bar in a manner so as to cause the mold to wrap around the drum arrangement and separate the concrete product from the mold.
Claims16
A mold for forming a cast concrete product, comprising:
- a mold body formed of a flexible and resilient material and having at least one cavity to form the concrete product, the mold body having a leading end opposite a trailing end;
- and
- an engagement member carried by the mold body, wherein the engagement member extends laterally outwardly relative to the mold body, wherein the engagement member comprises a bar that extends laterally through the mold and defining a pair of ends that extend laterally outwardly relative to side surfaces defined by the mold, and wherein the bar is secured to the mold via a laterally extending sleeve in the mold, wherein the sleeve defines a lateral passage through which the bar extends.
A system for demolding a cast concrete product, comprising:
- a rotating drum arrangement;
- a catch member that rotates with the drum arrangement;
- a mold having at least one cavity to form the concrete product, wherein the mold has a leading end and a trailing end and includes an engagement member located toward the leading end,
- wherein the rotating catch member is configured to engage the engagement member in a manner so as to restrain the mold against a cylindrical surface defined by the rotating drum arrangement so as to cause the concrete product to separate from the mold.
