Abstract
A foam molding apparatus with improved seal for sealing the mold lid to the bowl. The bowl and lid include inclined sealing surfaces surrounding the mold cavity with the bowl sealing surfaces being concave and the lid sealing surface being convex. Both the bowl and lid are resiliently supported on frames so that the lid can self align upon the bowl as the convex lid sealing surface engages the concave bowl sealing surface. Adjusting screws are carried by the lid carrier frame and engage the lid to apply pressure to the lid forcing the lid against the bowl sealing surface with the bowl being resiliently carried on a supporting frame allowing the bowl to float relative to the frame to achieve an even pressure distribution about the mold cavity at the sealing surfaces. The lid and bowl are both formed with fluid passages to enable hot water to be circulated through the mold maintaining the mold at an elevated temperature.
