Detailed Description
The utility model discloses the exhaust apparatus of mould is applicable to the various moulds of production.
Referring to fig. 1, 2, 3, 4, 5, 6 and 7, preferred embodiments of the exhaust device of the mold of the present invention will be described in detail.
As shown in fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, fig. 6 and fig. 7, the utility model provides an exhaust apparatus 8 of mold, it includes air groove 8.1, exhaust gap 8.2 and exhaust duct 8.3, exhaust gap 8.2 with air groove 8.1 intercommunication, air groove 8.1 with exhaust duct 8.3 intercommunication, its characterized in that still includes evacuating device 8.4, evacuating device 8.4 is connected with exhaust duct 8.3, exhaust gap 8.2 divide into two or more, the size of each exhaust gap 8.2 is set for according to the difference of the mould position that exhaust gap 8.2 belongs to, evacuating device 8.4 connects gas source 9.
Because the mold cavity is originally gas, when liquid raw materials are injected into the closed cavity of the mold or the volume of the movable cavity is reduced, the gas in the mold cavity is discharged to the air channel 8.1 through the exhaust gap 8.2 and then discharged out of the mold through the exhaust channel 8.3, the vacuumizing device 8.4 is connected with the exhaust channel 8.3, and when the gas in the mold cannot be discharged in time, the vacuumizing device 8.4 is started to accelerate the gas in the mold cavity to be discharged.
