A backplate assembly for supporting the molds of blowmolding machines having plural molds wherein the backplate assembly consists of two planar plates having a resilient elastic compressible cushion disposed therebetween to permit limited self-adjustment of the plates as determined by pressure produced upon the mold halves closing. The cushion is formed by an elongated spirally configured elastic resilient strand located within recesses formed in the plates, and the configuration of the strand may be related to the distribution of compressive forces imposed on the backplate assembly.
