[0037] Working principle:

[0038] When the injection molding device for producing plastic products is actually used, the control panel is used to operate the electric telescopic rod 7, the drive motor 15 and the annular electric heater 19. The electric telescopic rod 7 is extended to insert the second mold 10 into the first mold 6. The output end of the drive motor 15 drives the auger 4 to rotate. The rotating auger 4 can push the melt inside the conveying cylinder 2 into the first mold 6 through the injection head 5. After stamping and molding, the electric telescopic rod 7 is shortened. When the first mold 6 and the second mold 10 are separated, the plastic product can fall on the upper part of the interception filter 13 through the guide bucket 11. At the same time, the rotating auger 4 drives the second pulley 27 to rotate by using the second sealed bearing 24. The rotating second pulley 27 drives the connecting shaft 29 to rotate through the first transmission belt 28 and the first pulley 25, and the rotating connecting shaft 29 drives the fan blades 26 to rotate.

The dry high-temperature gas can be sprayed out through multiple groups of branch pipes 30. The sprayed high-temperature gas can dry the cooled plastic products. The extracted sealing plug 12 can be removed from the plastic products through the intercepting filter 13. Clean water can enter the interior of the box body 1 through the water inlet pipe 8, and the clean water inside the box body 1 can be discharged through the water outlet pipe 9.

The valve arranged on the side wall of the tube 9 can open and close it, and the multiple sets of one-way valves 31 play the role of guiding the air flow. Through the arranged air guide tube 21, the cooled plastic products can be dried without adding electric equipment, thereby improving the practicality of the injection molding device for the production of plastic products. At the same time, according to the above operation, when the driving motor 15 is working, its output end can drive the auger 4 to rotate. By using the third sealed bearing 32 and the fourth sealed bearing 33, the rotating auger 4 drives the installation shaft 34 to rotate through two sets of third pulleys 35 and the second transmission belt 36. The rotating installation shaft 34 drives the eccentric wheel 18 to rotate. Since the length of the distal end of the eccentric wheel 18 is greater than The vertical length between the sieve plate 17 and the mounting shaft 34 and the length of the proximal end of the eccentric wheel 18 are less than the vertical length between the sieve plate 17 and the mounting shaft 34.

When the eccentric wheel 18 is separated from the sieve plate 17, the four groups of telescopic springs 39 can be pushed downward by the four groups of T-shaped rods 38 under the action of their own elastic force. The sieve plate 17 moving up and down can shake the impurities accumulated on the upper part thereof to avoid clogging of the sieve plate 17.
