[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that can use plastic molding molds to make thermoplastic plastics or thermosetting plastics into various shapes of plastic products. During the entire injection molding process, waste gas will be generated, and there will be a lot of dust and particulate matter in the waste gas. If the dust and particulate matter in the waste gas are not dealt with in time, it will cause pollution to the surrounding environment.

During the rotation of the first threaded rod 15, the two moving blocks 16 and the two first positioning blocks 18 are driven to move relative to each other, so that the two first positioning blocks 18 are respectively moved out of the inside of the two first positioning grooves 17, thereby releasing the fixation of the cover plate 2. At this time, the cover plate 2 can be lifted up to be removed, and then the two worms 252 can be driven to rotate by turning the two second hand wheels 253, and then the two second threaded rods 22 are driven to rotate through the two worm wheels 251, and the two second threaded rods 22 During the rotation process, the two second positioning blocks 24 will be driven to move away from each other, so that the two second positioning blocks 24 are respectively moved out from the inside of the two second positioning grooves 23, thereby releasing the fixation of the mounting frame 8.
