In cooling medium.Horizontal feed component 251 works at this time, and binder oil cylinder 252 is driven to be displaced toward 234 side of discharge port, due to
The lower lower section that can be tightly attached to pressure plate 253 of the density of moulding 30, and being swept gradually under the barrier effect of scraping wings 254
To 234 one end of discharge port.In addition plane at pressure plate 253 is located at the lower section of 231 hinged place of closed plate, when binder oil cylinder
252 continue be close to when 234 side of discharge port by driving, pressure plare can gradually open closed plate 231 and make closed plate 231 around
Hinge joint is rotated, and discharge port 234 is opened at this time while horizontal feed component 251 stops working as shown in figure 9, cooling be situated between
Matter is poured under gravity in splicing sink 24, at the same moulding 30 under the drive of cooling medium equally from discharge port
234 come out and enter in picking-up container 29 and collect.
After the cooling medium in cooling trough 23 almost all comes down in torrents light, start water circulating pump 27, it will be from cooling trough
The cooling medium received in 23 is returned in cooling trough 23, but since discharge port 234 at this time is also in open state,
It returns the cooling medium come to spray into from 233 side of water inlet, is trapped in exhausted small part to being washed away inside cooling trough 23
Moulding 30 washes away away in cooling trough 23, and water circulating pump 27 stops after all mouldings 30 come out out of cooling trough 23
If machine can skip this step without delay moulding 30 in cooling trough 23 certainly in a removal process.When completion is washed away
Horizontal feed component 251 works afterwards, and driving binder oil cylinder 252 resets, and the separating with closed plate 231 gradually of pressure plate 253 is closed
Plate 231 resets under the action of spring hinge and finally closes discharge port 234.Water circulating pump 27 is again turned on and mends at this time
Feed pump 28 is equally opened, and cooling down operation of the cooling medium for next time is injected into cooling trough 23, and to cooling trough
In 23 when injection cooling medium, picking-up container 29 can artificially be taken out from splicing sink 24, and all mouldings 30 from splicing
It pours out in case 29, picking-up container 29 is put into splicing sink 24 again after recycling is good.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
