Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
185 words
In a device for producing moldings from foamable plastics, more particularly, polyurethane, wherein a two-part mold is arranged in a mold support pivotable about at least a first axis disposed in the direction of closing of the mold and about a second axis arranged at right angles to the first axis in the center of concentration of the mold support and wherein the two ends of the first axis pass through the arms of a U-shaped bow which is disposed about the mold support and mounted on the frame on its rear stem side along the line of the second axis, the improvements comprising the mold support (11) has a table-shaped clamping plate (12), a pressure yoke (13), a a traverse bar (14), and two guide and displacement devices (17,18) for the pressure yoke (13); said guide and displacement devices (17,18) being arranged opposite each other in an off-set position approximately along the line of a diagonal (19) of the clamping plate (12) and the guide rods (28,29) of the guide and displacement devices (17,18) interconnecting the clamping plate (12) and the traverse bar (14).
