Abstract

A mold for manufacturing a corner-shaped simulated stone product has a mold cavity configured to imprint a stone texture on at least a first side face and a front face of the corner-shaped product. The mold also provides a back face with a desirable molded interior angle. The mold cavity can have a flexible edge around a perimeter of the mold cavity to impart a textured surface to a second side face of the corner-shaped product.

Claims (6)

1. A mold for manufacturing simulated stone products, the mold comprising: a flexible layer having the form of a natural stone, the flexible layer being configured to define a plurality of corner-shaped mold cavities, and a portion of the flexible layer being in the form of support sections dividing the mold into the individual corner shaped mold cavities; wherein each corner-shaped mold cavity has a first mold section in communication with a second mold section, the first mold section being oriented at a desired interior angle with respect to the second mold section, the first mold section having an inner side wall, an outer side wall, a bottom wall, and an end wall forming a top opening, the second section having an inner side wall, an outer side wall, a bottom wall, and an end wall forming a top opening, with the first mold section and the second mold section lying in the same horizontal plane so that castable material can be introduced into the mold cavity through the top opening, the mold cavity further including a perimeter edge extending inwardly around at least a portion of an upper perimeter of the mold cavity, the perimeter edge configured to imprint a stone texture on at least a portion of the corner-shaped stone product;

wherein the inner side walls, outer side walls, bottom walls and the end walls of the mold are configured to imprint onto castable material introduced into the mold a texture that simulates a natural stone texture.

2. A mold for manufacturing simulated stone products, the mold comprising: a flexible layer having the form of a natural stone, the flexible layer being configured to define a plurality of corner-shaped mold cavities, and a portion of the flexible layer being in the form of support sections dividing the mold into the individual corner shaped mold cavities; wherein each corner-shaped mold cavity has a first mold section in communication with a second mold section, the first mold section being oriented at a desired interior angle with respect to the second mold section, the first mold section having an inner side wall, an outer side wall, a bottom wall, and an end wall forming a top opening, the second section having an inner side wall, an outer side wall, a bottom wall, and an end wall forming a top opening, with the first mold section and the second mold section lying in the same horizontal plane so that castable material can be introduced into the mold cavity through the top opening, the mold cavity further including a perimeter edge extending inwardly around at least a portion of an upper perimeter of the mold cavity, the perimeter edge configured to imprint a stone texture on at least a portion of the corner-shaped stone product; wherein the perimeter edge extends from at least the outer sidewall of the mold cavity;

wherein the inner side walls, outer side walls, bottom walls and the end walls of the mold are configured to imprint onto castable material introduced into the mold a texture that simulates a natural stone texture.

3. A mold for manufacturing simulated stone products, the mold comprising: a flexible layer having the form of a natural stone, the flexible layer being configured to define a plurality of corner-shaped mold cavities, and a portion of the flexible layer being in the form of support sections dividing the mold into the individual corner shaped mold cavities; wherein each corner-shaped mold cavity has a first mold section in communication with a second mold section, the first mold section being oriented at a desired interior angle with respect to the second mold section, the first mold section having an inner side wall, an outer side wall, a bottom wall, and an end wall forming a top opening, the second section having an inner side wall, an outer side wall, a bottom wall, and an end wall forming a top opening, with the first mold section and the second mold section lying in the same horizontal plane so that castable material can be introduced into the mold cavity through the top opening, the mold cavity further including a perimeter edge extending inwardly substantially around the upper perimeter of the mold cavity, the perimeter edge configured to imprint a stone texture on at least a portion of the corner-shaped stone product;

wherein the inner side walls, outer side walls, bottom walls and the end walls of the mold are configured to imprint onto castable material introduced into the mold a texture that simulates a natural stone texture.
