FIELD: metallurgy.
SUBSTANCE: compound mould-complete set for usage on standard machines for blown die casting with drawing consists of halves of compound mould, which are agreeably installed on each plate of die-casting machine. Each half of mould allows system of slots of mould for die casting and system of slots of blown mould for blow melting with drawing of performs into blown products. Corresponding different slots are located so that they are open in the same direction of mould separation. Mould-complete set is provided for usage in method of moulding of plastic products, according to which in slot of mould for die casting it is casted perform under pressure, which is then blown out in form in slot of blown mould. Mould contains system of slots of mould for die casting and system in essence of elongated slots of blown mould, allowing each neck area. Each slot of each system is formed at least by two parts of mould, implemented with ability of separation in corresponding direction of its separation. Separation direction of slots of mould for die casting and slots of blown mould it is formed common direction of separation of mould, so at operation mould can be opened for release as die casted preforms, as and blown products. Longitudinal axis of slots of blown mould pass essentially perpendicularly to common direction of separation of mould, and its neck areas join to its external boundary, so that access to it is possible on the outside transversal to axis of opening and closing travel. Device for blown die casting or with drawing, of plastic products contains mould-complete set by invention. Method of blown moulding of plastic products, in which it is used mould-complete set, is formed by die casting of preform with usage of slots of mould for die casting; drawn and/or blown out in form of previously die casted preforms in slots of blown mould; it is opened mould-complete set for release of die casted preforms and blown products and there are traveled die casted preforms into slots of blown mould.
EFFECT: single-phase process, using low power consumption and ability to work with awkward shapes or products with width neck, not requiring expensive equipment.
