METHOD AND DEVICE FOR PRODUCING AN OPTIMIZED BASE CONTOUR ON PREFORMS

Номер: US20150021827A1

Автор: AKTAS Mahir

Принадлежит:

The present invention relates to a method and a device for producing a preform with a base geometry optimized for the subsequent stretch blow molding. The preform produced in the injection mold is removed in a cooled removal sleeve and cooled in the shaft by intensive contact cooling, while to the greatest extent no cooling contact is made with the domed preform end due to a special contour of the cooling sleeve. On account of the re-heating of this domed end that is possible as a result, the latter can be mechanically deformed into a new geometry that is more advantageous for the blow-molding process, and consequently also influenced in the wall thickness. In the subsequent blow-molding process, such a deformed preform has primarily the advantage that the polymer material distributed better in the bottle can lead to considerable material savings and to bottle bases of a higher quality. 120-. (canceled)21. A method for producing a preform with an optimized base geometry , comprising: producing a finished preform from at least one injection-molded thermoplastic material that has a substantially thinner wall thickness in a domed end region of the preform than in a preform shaft and the wall thickness of the preform gradually becoming equal in the progression from the gate to the preform shaft , the preform being intended for re-shaping into blow-molded containers; opening a mold after solidifying of an outer skin of the preform after first intensive cooling; taking up the preforms from the open mold by a removal arm and cooling sleeves of the removal arm , the cooling sleeves cooling the preform shaft , but not the domed region , by contact cooling before an embossing operation; correspondingly mechanically deforming , in dependence on cooling sleeve geometry , the still plastically deformable domed region reproducibly by an embossing body , a contour of the cooling sleeve and of the embossing body being designed so that these contours are to a greatest extent ...
