Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
As shown in fig. 1, the spherical self-lubricating casting mold comprises a mold body 1, wherein a cavity 11 is arranged in the mold body 1, a gate 12 communicated with the cavity 11 is arranged at the top of the mold body 1, a shell 2 is sleeved outside the mold body 1, a motor 3 is arranged on the inner side of the bottom of the shell 2, a cam 4 is arranged on an output shaft of the motor 3, a support shaft 5 is arranged at the bottom of the mold body 1, one end of the support shaft 5 is fixedly connected with the mold body 1, a roller 6 is arranged at the other end of the support shaft 5 through a rotating shaft, the roller 6 rotates around the rotating shaft, and the roller 6 is positioned above the cam 4 and is attached to the outer wall of the cam 4;
the top of the die body 1 is also provided with at least two exhaust channels 13 communicated with the die cavity 11. The motor 3 acts, make the cam 4 take place to rotate, when the cam 4 rotates to the peak, through the activity supporting role of the roller 6, make the mould body 1 be jacked up to the high-order and go out, when the cam 4 rotates to the minimum, the mould body 1 falls to the low level department, thus, through the rotational speed of controlling the motor 3, make the mould body 1 rise slowly, descend rapidly, realize the oscillation action to the mould body 1, thereby make the bubble of pressing from both sides in liquid float to the surface of liquid under the action of gravity, and break, the gas after breaking is discharged from exhaust passage 13, rational in infrastructure, can eliminate the bubble that produces in the casting process, guaranteed that the mechanical properties of mould body 1 is stable, reliable.
The die body 1 comprises an upper die holder and a lower die holder, locking pieces 7 are arranged on the outer edge of the bottom of the upper die holder and the outer edge of the top of the lower die holder, and the two locking pieces 7 are locked through bolts 70;
two opposite side walls of the shell 2 are respectively provided with a sliding groove 20, the two locking sheets 7 are respectively arranged in the sliding grooves 20 in a one-to-one correspondence mode, and the locking sheets 7 perform linear reciprocating motion in the sliding grooves 20 in the vertical direction. Realize the locking of stay 7 through bolt 70, ensured inseparable, firm laminating between upper die base and the die holder, simultaneously, the setting of spout 20 has ensured that stay 7 can not produce the interference with between the casing 2, ensures that mould body 1 can reliably carry out the reciprocating motion of vertical direction in casing 2.
The bottom of mould body 1 is equipped with a pair of spacing post 8, and is a pair of spacing post 8 is located respectively the both sides of back shaft 5, still be equipped with in the casing 2 a pair of with spacing post 8 respectively and one-to-one's sliding sleeve 9, spacing post 8 is inserted with establishing with the adaptation in sliding sleeve 9 and be in slide in the sliding sleeve 9. Through the cooperation of spacing post 8 and sliding sleeve 9 for mould body 1 is in the horizontality, has ensured not have the extrusion between the inner wall of mould body 1 and casing 2, has just also ensured that the bubble can be reliably discharged.
