ABSTRACT:
A mold structure having at least first, second and third mold parts stacked one on top of the other, each having structure thereon defining at least one part of a mold cavity. The second part is oriented between the first and third parts and has mold cavities on both sides thereof. A support structure is provided for supporting the first mold part for movement toward and away from the third mold part. Structure is included within the mold structure to limit the spacing between the first and second mold parts to a prescribed spacing so that as the first mold part is moved away from the third mold part, the second mold part will be spaced a prescribed distance away from both the first and third mold parts.
The invention also includes a mold opening structure which is coaxially aligned with the elongate tie rod extending between the mold parts. This structure further effects a safe and positive opening of the mold structure.
