Abstract
Downward force resulting from the block mold and its carrier of the upper mold assembly which move downwardly toward the upstream end of the mold cavity defined by the vertically spaced-apart upper and lower mold assemblies is transmitted to the block mold and its carrier of the upper mold assembly passing the upward path extending upwardly from the downstream end of the mold cavity so that the distortions of the cross-sectional configuration and size of the mold cavity due to the weight of the block molds and their carriers are prevented.
