DEVICE FOR INJECTION-MOULDING PART Russian patent published in 2016 - IPC B22C7/02 

Abstract RU 2603756 C2

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, particularly parts of a wax model. Device comprises two blocks with cavities which, after superposition of blocks one on another, corresponds to shape of cast part (25). In cavity 6 of block there is rod 10 defining shape of cooling circuit of cast part. Lower block (4) is equipped with means of positioning rod 10 in form of support surfaces (8, 9) and presser screw screwed (13, 14) screwed into threaded opening of block (4.) Presser screws hold rod in position opposite support surfaces (8, 9). Force applied to rod by screws is limited by means located between head and threaded part of clamping screw.

EFFECT: preventing destruction and displacement of rod.
