And a dust collecting hopper is arranged between the bottom die upper support and the bottom die lower support.
The bottom die lower support bottom be equipped with the hydro-cylinder fixed plate, through hydro-cylinder fixed plate installation hydro-cylinder, the output of hydro-cylinder passes bottom die lower support and bottom die upper support in proper order and connects the dabber.
And a dismounting chain is arranged between the lower part of the outer die and the upper part of the bottom die fixing component, and two ends of the dismounting chain are respectively connected with the lower part of the outer die and the upper part of the bottom die fixing component through chain locking screws.
Compared with the prior art, the utility model discloses the beneficial effect who has is:
the utility model discloses change traditional mouth of a river brick forming die structure, adopt the shaping mode that mould reciprocated on upper portion, with dabber bottom fixed connection hydro-cylinder output, it removes to drive the dabber through the hydro-cylinder and be oscilaltion, thereby realize the even suppression of freedom of material, and then form the adobe, it is concrete, utilize the dabber of whereabouts and the outer mold cloth that rises below mouth of a river brick annular step, then utilize the last mould of lapse and the brick body part of unsteady outer mold suppression step below, it is even to guarantee brick body density, the suppression of the die block assembly body reunion, finally form the even adobe of bulk density. The volume density of the nozzle brick can be improved, the condition of uneven volume density is improved, the porosity of the brick is reduced, the scouring resistance strength of the nozzle brick is improved, and the production efficiency of the nozzle brick is improved. And the requirement of the brick body size on the floating range is easily met, and the application range is wider.
