Abstract
Abstract Pressure molding device comprising a core fixed to a support driven in a horizontal sliding movement along a vertically mobile plate, from a position immediately adjacent to the mold to a position at a distance from the said mold and vice-versa, means being provided for positioning the said support exactly adjacent to the said mold before the molding operation. The invention can be used more particularly for molding storage cell containers having a great height.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
207 words
In a pressure molding device of the type including a core supported by a mobile plate which is vertically displaceable so that said core is movable into and out of engagement with a subjacent mold mounted on a fixed plate, means for adjusting said mobile plate comprising drive means for driving said core with a horizontal sliding movement between one position in which it is arranged immediately adjacent to the said mold and a second position in which it is at a distance from the latter, adjusting means for positioning the said core on said mobile plate exactly in registration with the said mold before vertical movement of said mobile plate prior to the molding operation, and locking means for selectively tightening said support against said mobile plate including at least one flange movably supported on a bolt mounted on said mobile plate and pressing means for selectively pressing said flange against said support, characterized in that said drive means for moving said core with a horizontal sliding movement includes a support movable on the surface of said mobile plate facing said mold, and in that said support is driven with a sliding movement by means of rollers thereon rolling on rails secured to said mobile plate.
Claim 2
Dependent Claim
207 words
In a pressure molding device of the type including a core supported by a mobile plate which is vertically displaceable so that said core is movable into and out of engagement with a subjacent mold mounted on a fixed plate, means for adjusting said mobile plate comprising drive means for driving said core with a horizontal sliding movement between one position in which it is arranged immediately adjacent to the said mold and a second position in which it is at a distance from the latter, adjusting means for positioning the said core on said mobile plate exactly in registration with the said mold before vertical movement of said mobile plate prior to the molding operation, and locking means for selectively tightening said support against said mobile plate including at least one flange movably supported on a bolt mounted on said mobile plate and pressing means for selectively pressing said flange against said support, characterized in that said drive means for moving said core with a horizontal sliding movement includes a support movable on the surface of said mobile plate facing said mold, and in that said support is driven with a sliding movement by means of rollers thereon rolling on rails secured to said mobile plate.
Claim 3
Dependent Claim
54 words
Device according to claim 1, characterized in that said adjusting means for positioning the core consists of two chocks secured to the mobile plate in an adjustable manner so as to be capable of being shifted on the latter, and a shoulder provided on said support to rest against each of the said chocks.
Claim 4
Dependent Claim
33 words
Device according to claim 2, characterized in that the contacting faces of the said chocks and said shoulders consist of flat surfaces cut substantially at 45* to the axis of said mobile plate.
Claim 5
Dependent Claim
32 words
Device according to claim 1, characterized in that said locking means includes a plurality of bolts having flanges and said pressing means includes cam means on each bolt for displacing said flanges.
Claim 6
Dependent Claim
30 words
Device according to claim 4, characterized in that said cam means includes a cam bearing on a ring retained substantially on the upper part of each of the said bolts.
Claim 7
Dependent Claim
