DEVICE FOR MOULDING OF ITEMS Russian patent published in 2015 - IPC B28B1/26 B28B1/08 

FIELD: construction.

SUBSTANCE: device for moulding of items comprises a matrix, a core, units for their mutual coaxial installation and replenishment. At the same time the device is equipped with a disk membrane fixed on the matrix with the help of a unit of coaxial installation and a beam of arc type, which by their sides is fixed on the upper plane of the disk membrane. Besides, the device is equipped with a vibrator having a working tip installed coaxially to the core, the body of which is rigidly fixed on the beam. Besides, the working tip rests against the membrane in its central point. At the same time the end of the core is rigidly fixed in the centre of the lower plane of the disk membrane, and its external surface is made with longitudinal grooves. Besides, height h and pitch s of the grooves are equal to 1/200 D, where D - diameter of the core.

EFFECT: improved quality of produced items due to reduction of a coefficient of friction of a used mix against walls of a matric and a core.
