INSTALLATION FOR MOLDING OF THE ARTICLES MADE OUT OF THE SEMIDRY CONSTRUCTION MIXTURES Russian patent published in 2007 - IPC B28B1/87 

FIELD: building materials industry; devices for molding of the articles made out of the building mixtures.

SUBSTANCE: the invention is pertaining to the field of building materials industry, in particular, to production of the articles made out of the precast concrete from the semidry building mixtures. The invention presents the installation for molding of the articles made out of the building mixtures, which consists of the mounted stand with the guiding columns connected by the horizontal cross bar with the power cylinder, which coupling rod is pivotally connected to the plunger. The plunger is mounted on the upper horizontal crossbar enveloping the guiding columns. Under the plunger and coaxially to it there is the bottomless mould installed on the lower cross bar. The mold has the replaceable bushing forming the shaping cavity and contacts through the replaceable underpan with the movable frame of the vibration bed. The lower vertically movable horizontal cross bar is kinematically connected to the stabilizer of the parallel relocations of the bottomless mold. The rear butt of the stand is adjoined with the support frame of the distributing tool. The distributing tool consists of the guiding desk with the distributing bin and the placed under it the box-type feeding mechanism. The box-type feeding mechanism is supplied with the turner made in the form of the driven grate. On the support frame under the guiding desk there is the gear of delivery of the replaceable plug-in reusable underpans. The forward butt of the stand is adjoined with the reception table established symmetrically to the gear of delivery of the replaceable plug-in reusable underpans. At that the length L of each telescopic lever of the stabilizer of the parallelism of relocations in the vertical plane of the bottomless mold and the height Н of the working cavity of the replaceable bushing exceed the length L₁ of each support lever of the stabilizer of the parallelism of the relocations in the vertical plane of the bottomless mold and the height h of the bottomless mold accordingly in 1.5-2.5 and 1.15-2.25 times. At that the clearance α in the horizontal plane between the inner surface of the transversal walls of the box-type feeding mechanism and the extreme transversal rods of the grate of the turner and the distance h₁ from the lower surface of the grate of the turner up to the lower butt of the box-type feeding mechanism is less than the length L₂ of the meshes between the adjacent transversal rods of the grate of the turner and the height Т of the box-type feeding mechanism of the latter accordingly in 2.5-75 and45-70 times. The technical result of the invention is reduction of the power and working areas demand, the increased efficiency, reliability, simplicity of the equipment operation and the personnel functioning, reduction of the operational noise level.

EFFECT: the invention ensures the reduced power and working areas demand, the increased efficiency, reliability, simplicity of the equipment operation and the personnel functioning, the reduced operational noise level.
