The bottom end of the dispersion pipe 10 is provided with a tank body 12. The bottle mouth of the tank body 12 is threadedly engaged with the outside of the dispersion pipe 10. A filter element 13 is fixedly arranged in the tank body 12, and the filter elements 13 are equidistantly distributed in the tank body 12. The collecting mechanism 4 is arranged above the molding mechanism 3. During the compression molding process, the generated flue gas can be transferred into the transverse pipe 9 through the action of the air pump 6, and then guided into the tank body 12 through the dispersion pipe 10. The filter elements 13 arranged inside the tank body 12 can purify the flue gas, thereby reducing the harm to the environment and personnel. And the provided valve 11 enables personnel to carry out an indirect replacement and alternating use work in two categories. A baffle 14 is fixedly installed on the outside of the dispersion pipe 10, and the baffle 14 abuts against the top end of the bottle mouth of the tank body 12. By providing the baffle 14, the position of the tank body 12 can be positioned. Grooves 15 are opened on the outside of the tank body 12, and the grooves 15 are equidistantly distributed on the outside of the tank body 12. By providing the grooves 15, it is convenient for personnel to rotate the tank body 12. The compression molding machine and the valve 11 in this article are both prior arts, so the principles and structures are not elaborated in detail here.

[0025] As Figure 1 and Figure 2As shown in the figure, a long strip plate 16 is fixedly installed on the machine base 1. The top end of the long strip plate 16 abuts against a top cover plate 5. A limiting groove 17 is opened at the top end of the long strip plate 16. A moving plate 18 is inserted into the limiting groove 17. The moving plate 18 is fixedly installed on the bottom end of the top cover plate 5. A screw rod 19 is meshed and connected inside the moving plate 18. The screw rod 19 is rotatably connected inside the limiting groove 17. The other end of the screw rod 19 is fixedly connected to the rotating shaft of a servo motor 20.

The side plate 22 is set in an L shape. An arc groove 25 is opened on one side of the side plate 22. There are two groups of the arc grooves 25. The two groups of arc grooves 25 are symmetrically distributed on the side plate 22. By providing the arc grooves 25, it is convenient for the personnel to pull the side plate 22.

[0027] The present utility model provides a compression molding machine for manufacturing plastic products. The specific working principle is as follows:

[0028] During the use of the device, with the start of the air pump 6, the flue gas can enter the exhaust pipe 8 through the intake pipe 7, then concentrate inside the horizontal pipe 9, and then disperse inside the dispersion pipe 10, so as to flow inside the tank body 12, enabling the filter element 13 inside the tank body 12 to purify the flue gas. And with the valve 11 provided on the dispersion pipe 10, the tank body 12 can be divided into two types for indirect replacement and alternating use. Subsequently, with the meshing and separation between the mouth of the tank body 12 and the dispersion pipe 10, it is convenient for personnel to replace the filter element 13 inside the tank body 12. When mold modification is required later, with the servo motor 20 driving the screw 19 to rotate, the moving plate 18 can move on the outer side of the screw 19 and inside the limit groove 17, so that the top cover plate 5 can move in position above the molding mechanism 3, thus facilitating the mold modification work on the molding mechanism 3 by personnel. And with the cooperation among the square hole 21, the side plate 22, the threaded hole 23 and the bolt 24, when personnel need to inspect the mold on the molding mechanism 3, by rotating the bolt 24, the side plate 22 can be pulled upward, enabling the side plate 22 to slide inside the square hole 21, thus facilitating the inspection work by personnel.
