FIELD: process engineering.
SUBSTANCE: invention relates to injection moulding machine structural components, particularly, to moulds and may be used for moulding large-size flat articles from rubber granules. Proposed mould comprises limiting frame, rigid all over its edges. Stepped plate is arranged inside said frame to move vertically therein. Plate top larger step rests on frame inner ledges. Plate bottom step extends from the frame bottom plane for plate upward travel. Support posts provided with elastic elements are coupled with said frame. Said posts make plate bottom support plane located below stepped plate support plane in plate bottom position on aforesaid ledges. Frame may be provided with wheels located outside of machine bottom movable plate. Stepped plate top plane may be provided with relief pattern. Also, plate bottom step may be made up of grid.
EFFECT: increased article thickness, stable geometrical sizes.
