Detailed Description
The technical solution of the present invention will be described clearly and completely below with reference to specific embodiments of the present invention, and it should be understood that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the embodiment provides a sand box bottom sand leaking device for an automatic production line of lost foam, which comprises a base 1, a locking frame 2 and a hook 6. Wherein, base 1 welds on the bottom plate of sand box, be provided with one on the base 1 with sand box sand outlet assorted round hole, this round hole cup joints in the sand box sand outlet outside, both sides at sand box sand outlet are provided with the otic placode respectively, two otic placodes and the center of round hole are located same straight line, there is the couple 6 of perpendicular setting through round pin axle swing joint on the otic placode of left side, through being connected with locking frame 2 through the round pin axle on the otic placode of right side, the side at the other end of locking frame 2 is provided with the connecting axle perpendicularly, the connecting axle overlap joint is on couple 6. A fixing shaft is arranged on one side, close to the base 1, of the locking frame 2, and the fixing shaft is perpendicular to the base 1 and is arranged coaxially with the sand outlet. The upper end of the fixed shaft is connected with a fixed seat 4, and the fixed seat 4 is used for sealing the sand outlet.
The round pin axle overcoat of coupling hook 6 and otic placode has cup jointed torsional spring 7, and the one end joint of torsional spring 7 is hanging, and the other end joint is on base 1, and torsional spring 7 is when not atress, and 6 perpendicular to horizontal planes in the couple. Simultaneously, the outer side of the sand outlet is sleeved with a sealing gasket 3, and the fixing shaft is provided with a buffer spring 5 in a surrounding mode so as to ensure the sealing effect of the fixing seat 4 on the sand outlet.
As shown in fig. 2, blocking wheels 8 are arranged at the front end and the rear end of the bottom station of the bottom sand leaking device and are used for opening and closing the sand outlet.
The specific working principle is as follows: when the bottom sand leaking device is in a closed state (figure 1), the sand box travels, the locking frame 2 is extruded through the blocking of the blocking wheel 8 by the blocking wheel 8 through the blocking of the blocking wheel 8, the buffer spring 5 is compressed, the connecting shaft on the locking frame 2 is separated from the hook 6, the sand box continues to travel, the blocking wheel 8 extrudes the hook 6 to rotate, the hook 6 is completely separated from the hook 6, finally the locking frame 2 falls off under the action of gravity, the bottom sand leaking device is in a completely opened state, and the molding sand falls through the sand leaking hole to complete a shakeout state. When the bottom sand leaking device is in an open state (figure 3), the sand box continues to travel, the locking frame 2 is extruded through the next group of blocking wheels 8 and the blocking of the blocking wheels 8, the buffer spring 5 is compressed, the connecting shaft on the locking frame 2 is hung with the hook 6, the fixing seat 4 is tightly combined with the elastic sealing gasket 3, and the bottom sand leaking device is in a closed state.
