As used in the description of the present invention, the terms "front," "back," "left," "right," "up," "down" and "in" refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

The utility model provides a specific embodiment provides an integrated circuit encapsulation plastic envelope updraft ventilator, as shown in FIG. 1, be the utility model discloses a look sideways at the schematic structure, the device includes overhead gage 1 on edge on the 6 opening parts of mould cavity, locates lower baffle 2 on edge under the 6 opening parts of mould cavity, and the 6 opening parts of mould cavity left and right sides also correspond and are equipped with left baffle and right baffle. An exhaust port 11 has been seted up to 1 intermediate position of overhead gage, exhaust fan 3 has been communicated through bleed-off pipeline 5 in the 11 outsides of exhaust port, the air-out end of exhaust fan 3 has air purification case 4 through bleed-off pipeline 5 intercommunication, air purification case 4's air-out end and external intercommunication.

The lower edge of the upper baffle plate 1 is fixedly connected with two ends of a motor 12 respectively, and a sealing cover plate 13 is fixedly connected between the rotating shafts of the two motors 12. When the motor 12 drives the sealing cover plate 13 to rotate reversely to a preset angle, the sealing cover plate 13 is just pressed on the outer side surfaces of the lower baffle 2, the left baffle and the right baffle, and the opening of the mold cavity 6 is just covered by the sealing cover plate 13, so that the mold cavity 6 is isolated from the outside. The lower baffle 2, the left baffle and the right baffle are made of rubber materials, so that the sealing effect of the die cavity 6 is enhanced. At this time, the seal cover plate 13 is in a closed state, i.e., a state in which the seal cover plate 13 is in fig. 1. When motor 12 drives sealed cover plate 13 forward rotation to predetermined angle, when sealed cover plate 13 is in the open mode, as shown in fig. 2, it is the embodiment of the utility model discloses a side view structure sketch map when sealed cover plate is in the open mode, the lateral surface of baffle 2 is equipped with a micro-gap electric door 21 down, this micro-gap

electric door

21 and 3 electric connection of air discharge fan.

When the mold is produced and maintained, an operator controls the motor 12 to drive the sealing cover plate 13 to rotate to a closed state, the sealing cover plate 13 is pressed on the micro-switch 21, the micro-switch 21 is in a switch-on position, the opening of the mold cavity 6 is just covered by the sealing cover plate 13, the edge of the sealing cover plate 13 is tightly pressed with the outer side surfaces of the lower baffle 2, the left baffle and the right baffle, the mold cavity 6 is isolated from the outside, and the toxic gas in the mold cavity 6 is prevented from overflowing. Because micro-gap switch 21 switches on, exhaust fan 3 begins work thereupon, extracts the toxic gas that has thorn nose smell in the mould die cavity 6 through gas vent 11 on the overhead gage 1 to carry toxic gas to air purification case 4 by exhaust fan 3's air-out end, be equipped with active carbon in the air purification case 4 for the toxic substance among the adsorbed gas, after toxic gas filters through air purification case 4, its toxicity and thorn nose smell greatly reduced to discharge in the outdoor air by air purification case 4's air-out end. When the production and maintenance of the mold are finished, an operator controls the motor 12 to drive the sealing cover plate 13 to rotate to an open state, the micro switch 21 is in a disconnected position, the exhaust fan 3 stops working, and at the moment, the operator can take and place plastic packaging raw materials and products into the mold cavity 6 through the opening of the mold cavity 6. In order to facilitate an operator to observe the working state in the mold cavity 6 at any time during production and maintenance of the mold, the sealing cover plate 13 is made of transparent organic glass.
