firstly, a lifting motor 11, a rotating motor 21 and an adjusting motor 41 are respectively electrically connected with an external power supply through power lines, matched crucible mold cylinders 3 and a downward-pressing circular template 33 are selected according to the diameter of a graphite crucible to be produced, the crucible mold cylinders 3 are placed in the middle on the top surface of a circular support 2 by holding a fixed handle 31 tightly, a polygonal clamping block 26 is clamped in a polygonal clamping cylinder 25 in a matched mode, and limiting clamping rings 27 are clamped in limiting groove steel rings 28 in a matched mode, so that the stability of the crucible mold cylinders 3 placed on the circular support 2 is improved;
step two, according to the diameter of the downward pressing circular template 33, starting an adjusting motor 41, driving an adjusting shaft 42 and a driving gear 43 to synchronously and slowly rotate by a motor shaft of the adjusting motor 41, sequentially driving a plurality of driven gears 46 and a linkage shaft 45 to synchronously rotate through meshing, driving a plurality of L-shaped long rods 47 to rotate to correspond to positioning holes in the downward pressing circular template 33, stopping the adjusting motor 41, slidably sleeving T-shaped flange rings 34 on the tops of the positioning long rods 44, enabling each L-shaped long rod 47 to be inserted in the corresponding positioning hole in a matched and penetrating manner, and carrying out spiral locking on the fixed flange rings 35 and the T-shaped flange rings 34 through a plurality of bolts 36, so that the stability of the downward pressing circular template 33 and the L-shaped long rods 47 is improved;
step three, starting the rotating motor 21, driving a first bevel gear 22 to synchronously rotate by a motor shaft of the rotating motor 21, meshing and driving a second bevel gear 24, a rotating shaft 23 and a polygonal clamping block 26 to synchronously rotate, further driving a polygonal clamping cylinder 25 and a crucible mold cylinder 3 to rotate, driving a limiting clamping ring 27 to rotate along a limiting groove steel ring 28, rotationally adjusting the crucible mold cylinder 3, adding a proper amount of graphite aggregate into the crucible mold cylinder 3, increasing the uniformity of feeding, and stopping the rotating motor 21 after the feeding is finished;
step four, starting the lifting motor 11, driving a lifting shaft 12 and a pair of third bevel gears 15 to synchronously rotate by a motor shaft of the lifting motor 11, driving a fourth bevel gear 16 and a screw 14 to synchronously rotate by meshing, further driving a screw cylinder 17 to be matched with the screw 14 to spirally lift, driving the circular support 2 and the crucible mold cylinder 3 to lift upwards through a lifting block 18, enabling a plurality of L-shaped long rods 47 and positioning long rods 44 to be uniformly inserted in the crucible mold cylinder 3, and driving the downward pressing circular template 33 to press the graphite aggregate downwards along the inner wall of the top port of the crucible mold cylinder 3;
and step five, after the graphite crucible is pressed and formed, controlling the crucible mold cylinder 3 to descend, taking out the crucible mold cylinder 3 through the fixed handle 31, and taking out the formed graphite crucible.
The crucible mould pressing mechanism solves the problems of inconvenience in crucible mould replacement and low pressing efficiency in the production process of the graphite crucible by the cooperation of the mechanisms, has compact overall structure design, increases the stability of the graphite crucible in the pressing process, and facilitates the replacement of crucible moulds with different diameters.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
