Abstract
A pour mold includes two parts one of which forms a mold cavity and the other of which forms the lid for the mold cavity; the lid includes a retractable pilot pin and vacuum cups for positioning a mold insert within the mold cavity automatically upon lid closure. The pilot pin loosely pilots the insert in the mold as it closes and as the vacuum cups pull the insert toward the lid during such closure. The vacuum cups hold the insert against the lid continuously during foam injection, foam reaction and cure and as the lid is separated from the mold cavity part so as to automatically remove the finished part from the mold when the lid is separated therefrom.
