Abstract
Изобретение относитс к переработке полимерных материалов, в частности к формам дл лить под давлением. Цель изобретени - повышение надежности в работе литформы при литье крупногабаритных изделий за счет обеспечени надежности извлечени литника. Дл этого в ползуне 6 выполнен развод щий литниковый канал 9 с поднутрением в виде ласточкина хвоста и сужающимс к плоскости разъема поперечным сечением 11. Поднутрение выполнено вдоль всего развод щего канала 9. 3 ил.The invention relates to the processing of polymeric materials, in particular to molds for injection molding. The purpose of the invention is to improve the reliability of the mold in the casting of large-sized products by ensuring the reliability of the extraction of the sprue. For this purpose, in the slider 6, the spreading gating channel 9 is made with a dovetail undercut and a cross section 11 tapering to the plane of the connector. The undercut is made along the entire spreading channel 9. 3 sludge.
