Processing mold including unitary movable mandrel for preparing tire support

A processing mold for preparing a tire support having a wheel-rim surface, a tread-support surface surrounding said wheel-rim surface, and an internal configuration between said tread-support surface and said wheel-rim surface, said processing mold comprising:

• a. a unitary movable mandrel having a longitudinal axis and a diametrical axis, said mandrel comprising:
• i. a first end and a second end being spaced along said longitudinal axis, said first end comprising a first mold-body contact and said second end comprising a second mold-body contact;
• and
• ii. a mandrel body longitudinally interconnecting said first end and said second end, said mandrel body comprising a mandrel wall that defines an outer dimension of said mandrel body, said outer dimension being along said diametrical axis, said mandrel wall being suitable for defining said wheel-rim surface;
• b. a first mold body comprising:
• i. a first mandrel contact being engaged with said first mold-body contact of said mandrel to form a first engagement;
• and
• ii. a first mold support;
• c. a second mold body opposing said first mold body, said first mold body and said second mold body being aligned by said mandrel, said second mold body comprising:
• i. an inlet for receiving fluid polymeric or prepolymeric material;
• ii. a second mandrel contact being engaged with said second mold-body contact of said mandrel, said second mandrel contact being adjacent to said inlet and comprising a distribution port in fluid communication with said inlet;
• and
• iii. a second mold support, said second mold support meeting said first mold support, said first mold support or said second mold support or both defining said tread-support surface;
• iv. four movable mold plates, said movable mold plates defining a tread-support surface of a tire support;
• v. a fifth mold plate adjacent said four movable mold plates;
• and
• vi. a stripper plate between said fifth mold plate and said four movable mold plates, said stripper plate to facilitate ejection of said tire support from said processing mold and
• d. a tire-support region for molding a tire support, said tire-support region being defined by said mandrel wall, said first mold support, and said second mold support, and said tire-support region being in fluid communication with said distribution port.
