Molds having sealable column pieces and methods of producing products therewith

A method, comprising:

• coupling a first mold piece and a second mold piece of a mold to provide a sealed mold cavity therebetween, the mold cavity defined by a first wall of the first mold piece and a second wall of the second mold piece, wherein coupling the first mold piece and the second mold piece causes mating of a first column member protruding from the first wall and a second column member protruding from the second wall, wherein a first distal end of the first column member is received within a cavity in a second distal end of the second column member and a seal is formed between the first distal end and the second distal end, wherein the mold includes a sealing element on at least one of the first distal end and the second distal end, and the method includes mating the first column member and the second column member such that the sealing element reduces a likelihood of wear on the first column member and the second column member;
• disposing a product material into the mold cavity;
• and
• solidifying the product material to form a product therefrom, wherein first sidewalls of the first column member and second sidewalls of the second column member define a pass through in the product.

A mold, comprising:

• a first mold piece having a first wall with a first column member protruding from the first wall, wherein the first column member includes first sidewalls and a first distal end;
• a second mold piece having a second wall with a second column member protruding from the second wall, wherein the second column member includes second sidewalls and a second distal end that includes an opening to a cavity defined by interior walls of the second column member, wherein the first mold piece and the second mold piece are configured to releasably mate with the first wall and the second wall defining a mold cavity therebetween, wherein the first column member and the second column member are configured to releasably mate while the first mold piece and the second mold piece are mated with the first distal end of the first column member being at least partially received within the cavity of the second distal end of the second column member and a seal is formed between the first distal end and the second distal end, wherein the first distal end includes more than one protrusion and the second distal end includes more than one recess, and each of the more than one recesses are configured to receive a corresponding one of the more than one protrusions;
• and
• a sealing element on at least one of the first distal end and the second distal end that is configured to promote the seal between the first column member and the second column member while the first column member and the second column member are mated,
• wherein the mold cavity is configured to receive a product material therein and form a product therefrom, and wherein the first sidewalls and the second sidewalls are configured to define a pass through in the product.
