Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 to 2, the utility model discloses a fume extractor for injection molding machine, include: the device comprises a machine table 1, wherein a feeding port 2 is arranged on the machine table 1; a smoke suction hood 3 provided above the injection port 2; the smoke distribution plate 4 is detachably connected in the smoke absorption cover 3; and the smoke exhaust pipeline is arranged on the machine table, one end of the smoke exhaust pipeline is inserted into the smoke suction hood 3, the other end of the smoke exhaust pipeline is provided with a smoke exhaust port 5, the smoke exhaust port 5 is arranged on the side of the machine table 1, and the smoke exhaust pipeline can exhaust smoke sucked from the smoke suction hood 3 from the smoke exhaust port 5.

Injection gate 2 that sets up on board 1 is used for injecting the raw materials of moulding plastics of molten state in to injection mould, during the clout of discharging, smoke sucking pipe way and discharge from exhaust port 5 can be inhaled with the cigarette that gives out from injection gate 3 to the suction hood 3 that sets up in injection gate 2 top, thereby the quick workshop of discharging the smog of injection gate exhaust, avoid these smog that contain the sulphide to cause the injury to the staff in the workshop, the cigarette that inhales the suction hood at first contacts with cloth cigarette board 4 and gives cloth cigarette board 4 with heat transfer, later again with the smoking, 3 contacts, thereby prevent high caloric cigarette and 3 direct contact of suction hood, prevent that suction hood 3 from being scalded by the cigarette of high caloric, finally can increase the life of suction hood 3, and after working a period, can make things convenient for the dismouting of cloth cigarette board 4 more with 3 detachable connected mode of suction hood. The exhaust port 5 that sets up in board 1 side can be used for connecting suction fan or other negative pressure devices, forms the negative pressure in the exhaust pipe to make smoke absorption cover 3 have the function of smoking, and exhaust port 5 sets up and is favorable to arranging of injection molding machine in the workshop in board 1's side, improves the utilization efficiency in workshop space.

The detachable connection between the smoke suction hood 3 and the smoke distribution plate 4 can be threaded connection, namely, threaded holes are formed in the smoke suction hood 3/the smoke distribution plate 4, bolt through holes are formed in the positions corresponding to the smoke distribution plate 4/the smoke suction hood 3, or threaded holes are formed in the smoke suction hood 3 and the smoke distribution plate 4, and finally the smoke suction hood 3 and the smoke distribution plate 4 are connected together through bolts; the detachable connection between the smoke suction hood 3 and the smoke distribution plate 4 can also be connected together in a buckling mode, namely, a buckle is arranged on the smoke suction hood 3/smoke distribution plate 4, a clamping groove is arranged on the smoke distribution plate 4/smoke suction hood 3, and the buckle is clamped in the clamping groove to connect the smoke distribution plate 4 and the smoke suction hood 3 together.

As shown in fig. 2, a plurality of through holes 6 are arranged on the smoke distribution plate 4 in a matrix manner, after the smoke suction hood 3 sucks smoke into the lower end face of the smoke distribution plate 4, the smoke enters the smoke suction hood 3 from the through holes 6 on the smoke distribution plate 4, the through holes 6 are arranged to form a cooling channel between the smoke distribution plate 4 and the smoke suction hood 3, so that the smoke with higher heat can be primarily cooled in the cooling channel, the temperature of the smoke sucked into the smoke suction hood 3 is lower, and the damage of the smoke suction hood 3 caused by the high heat smoke is reduced.
