[0002] The sand shakeout machine is a casting equipment that uses vibration and impact to separate the sand and casting in the mold. The vibration sources of the sand shakeout machine are divided into three categories: mechanical, electromagnetic and pneumatic. The mechanical inertial sand shakeout machine is widely used. The structural characteristics of the inertial sand shakeout machine are: the sand shakeout grid bed is equipped with a rotating shaft with a eccentric weight. When the shaft rotates, the eccentric weight generates centrifugal force, which makes the sand shakeout grid bed installed on the supporting spring vibrate. This vibration is a superposition of free vibration and forced vibration. The load size can change the amplitude. If the load is too large, the amplitude decreases sharply and the sand shakeout efficiency decreases; if the load is too small, the vibration is too large, which damages the sand box and equipment. For this reason, a fixed bracket should be installed on this type of sand shakeout machine to form an inertial impact sand shakeout machine.
[0003] The existing sand-falling machine has an open top structure, which may cause the following problems: the existing sand-falling machine has an open top, and when the mold is placed on the sand-falling machine, the vibration of the sand-falling machine may cause the sand-falling machine to separate the mold sand and the casting, thereby causing a large amount of dust to float in the air, causing serious air pollution in the morning.
