Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Embodiment
The embodiment of the present invention is described in further detail below in conjunction with accompanying drawing.
Provided by Fig. 1, a kind of molding sand cooling device, including cooling housing 1, it is characterised in that it is described to cool down the upper of housing 1
Portion is provided with molding sand entrance 101, air-cooled set 2 is fixed with the cooling housing 1, the air-cooled set about 2 is opened and it is open just
To molding sand entrance 101 and it is more than molding sand entrance 101, cold air duct 202 is provided with the air-cooled set 2, air-cooled set 2 is provided with and cold wind
The air inlet and air outlet that passage 202 is connected, 2 bottoms of the air-cooled set are provided with screen cloth 3, and the screen cloth 3 is positioned at cooling housing 1
Interior to be slidably connected with the cooling level of housing 1, screen cloth 3 is connected with driving 3 reciprocating drive device of screen cloth, the screen cloth 3
Lower end is provided with cooling water pipe 4, and multiple vertical fin 5 are interval with the cooling water pipe 4.The cooling water pipe 4 and dissipate
Backing 5 is respectively positioned in cooling housing 1.Molding sand enters from molding sand entrance 101；Cool down in housing 1, first pass around air-cooled set 2 and carry out
Preliminary cooling, the air-cooled cooling circulated air being passed through in 2 that covers take away a heat of molding sand.Then molding sand is fallen on screen cloth 3, sieve
Net 3 does horizontal reciprocating motion, and molding sand thereon is vibrated, the molding sand of larger particles shaken it is scattered, then by small on screen cloth 3
Mouth is left out by mistake at cooling water pipe 4 and cooling cooling water pipe 4, the type more concentrated that screen cloth 3 will can also be fallen from air-cooled set 2 simultaneously
Sand shakeouts, and is fallen in the whole top of the fin 5 of cooling water pipe 4, because fin 5 and cooling water pipe 4 cause whole cooling shell
The temperature of body 1 can directly be radiated all than relatively low by air, while be scattered what is contacted with fin 5 and cooling water pipe 4
Molding sand can be by directly contacting radiating.Last molding sand is fallen at heat sink and cooling water pipe 4 through after radiating.
The screen cloth 3 is connected with fix bar 6, and the fix bar 6 stretches out cooling housing 1 and the 1 horizontal company of slip of cooling housing
Connect, the drive device includes motor 7, and the output shaft of motor 7 is fixedly connected with crank 8, is rotatablely connected on crank 8
There is connecting rod 9, one end of connecting rod 9 is connected one end rotation connection that its other end stretches out cooling housing 1 with fix bar 6 with crank 8.Electricity
Machine, which rotates, drives crank 8 to rotate, and then drivening rod 9 moves, so that screen cloth 3 does linear reciprocating motion, because screen cloth 3 and cold
But housing 1 is to do level to be slidably connected, and screen cloth 3 forms the slide block mechanism of crank 8 with connecting rod 9, crank 8.Motor, which rotates, to be driven
Screen cloth does linear reciprocating motion.
