Sand falling machine is a kind of equipment for removing sand core from the surface of casting, widely used in foundry industry, it mainly separates the sand core from the surface of casting by vibration, and realizes efficient and safe sand falling operation. The main components of the sand dropping machine include the frame and the base, in which the frame is supported by two rows of springs on the base of the machine, and the vibration motor generates the excitation force to promote the separation of the sand box and the sand, so as to realize the separation of the castings from the The sand box is separated from the sand, thus realizing the separation of the casting and the sand, as well as the crushing of the sand mass.
Sand falling machine is divided into two forms with conveying function and without conveying function.
Sand falling machine with conveying function: two vibration motors installed symmetrically and inclined on the resonator body rotate synchronously in the opposite direction, generating an excitation force at an inclination angle to the grid surface solidly connected with the resonator body. The vertical component of the excitation force so that the resonator body with a certain acceleration for sinusoidal motion, grid bed up and down movement impact on the casting above the casting so that it is thrown up and down, repeated impact so that the sand box, sand castings separated from each other, the sand is further crushed through the grid holes fall to the resonator body. The horizontal force of the excitation force makes the sand box, sand block and casting to be thrown up while moving forward for a certain distance, constantly thrown up, constantly moving, so as to realize the conveyance of sand while falling. At the same time, adjusting the angle of the eccentric block of the two motors can adjust the size of the excitation force, so as to improve the efficiency of sand dropping.
Sand falling machine without conveying function: a pair of symmetrical horizontal installation of the excitation motor reverse synchronous operation, the horizontal direction of the force is balanced each other, the vertical direction of the combined force so that the frame of the sand falling machine with a certain acceleration to do sinusoidal vibration (unloaded), the casting is thrown (with or without sand box), and then drop with the grating frame collision, the sand and the sand box, the casting and the sand separated from the sand, the sand broken through the grating holes fall back to the sand belt, because of the vibration motor, the sand falling and the conveyance. Sand belt, due to the direction of the combined force of the vibration motor is perpendicular to the plane of the grid, so the castings and sand can not be self-unloading, you need to use lifting machinery to lift off the machine, to complete the process of a casting sand drop.
The two types of sand dropping machine can be reasonably selected according to the actual needs of customers or site conditions, and its size can also be customized according to the actual site.
