The operating principle of the automatic molding production equipment for the Obe grinding balls is as follows:
When the casting machine stops at the first working position, molten metal on the casting machine is started to flow into a pouring gate piece of the first working position after a pouring cup, and is shunted into a plurality of grinding ball forming cavities through an inner cavity of the pouring gate piece, when the casting quantity reaches a set value, the casting machine starts to move towards the second pouring position, and the sequential casting of a plurality of pouring positions on a casting line is completed by analogy. After the pouring position on the pouring line is poured, the cooling circulation corresponding to the pouring position is started (each pouring position can be realized by arranging a switch valve at a liquid inlet and a liquid outlet corresponding to the pouring position), molten metal in the grinding ball forming cavity is cooled and shaped, after the cooling time reaches a set value, a first hydraulic cylinder corresponding to the pouring position is started, a lower movable die is moved downwards, after the lower movable die is moved downwards in place, a second hydraulic cylinder is started, a lower die main body is rotated around a supporting shaft, overturning is realized, after the lower die main body is overturned in place, under the action of gravity, the grinding balls drop into a slide carriage groove below from the grinding ball forming cavity, and drop into a conveyor along the slide carriage groove in a sliding manner, so that the output of the grinding balls is realized.
The alignment of the casting machine and the mould on the casting position can be realized by arranging a sensor at the upper end of the mould, and arranging a sensor at each casting position.
Although the embodiments of the present invention and the accompanying drawings have been disclosed for illustrative purposes, those skilled in the art will appreciate that: various substitutions, changes and modifications are possible without departing from the spirit and scope of the invention and the appended claims, and therefore the scope of the invention is not limited to the embodiments and the disclosure of the drawings.
