[0017] The following is combined with Figure 1 - Figure 5 This application is described in further detail.

[0018] Example:

[0019] An injection molding machine for automobile decorative parts, referring to Figure 1 - Figure 5, including an injection molding cylinder 1, a base 2 is provided on the right side of the injection molding cylinder 1, a motor 3 is fixed on the upper surface of the base 2, the injection molding cylinder 1 is rotatably connected to an auger rod 4, the right end of the auger rod 4 passes through the outside of the injection molding cylinder 1 and is fixedly connected to the output shaft of the motor 3, the outer surface of the auger rod 4 is located on the right side of the injection molding cylinder 1 and is fixed with a first gear 5, the top of the first gear 5 is meshed with a second gear 6, the right side above the outer surface of the injection molding cylinder 1 is connected to a feed cylinder 7, the top of the feed cylinder 7 is connected to a hopper 8, a piston 9 is slidably connected to the top of the feed cylinder 7, the bottom of the piston 9 is rotatably connected to a connecting rod 14, a rotating sleeve 13 is fixed to the bottom end of the connecting rod 14, the middle part of the rotating sleeve 13 is rotatably connected to a crank 12, the crank 12 is rotatably connected to the inside of the feed cylinder 7, the right end of the crank 12 passes through the outside of the feed cylinder 7 and is fixedly connected to the second gear 6.

[0020] Reference Figure 3 The upper surface of the feed barrel 7 is symmetrically provided with a slide groove 10, and the slide groove 10 is slidably connected to the inside of the slide groove 10. The two slide rods 11 are integrally formed with the piston 9. When the feed barrel 7 is rotated and pushed up by the crank 12 and the connecting rod 14, the slide rod 11 and the slide groove 10 play a guiding role to prevent the piston 9 from being unable to reset.

[0021] Reference Figure 3 -5. An inner groove 15 is provided on the right side of the feed barrel 7. The outer surface of the crank 12 is located inside the inner groove 15 and a third gear 16 is fixed thereto. The bottom end of the third gear 16 is meshedly connected to a fourth gear 17. The fourth gear 17 is rotatably connected to the inner groove 15. A swivel 18 is rotatably connected to the lower part of the inner groove 15. The swivel 18 is embedded below the inner side wall of the feed barrel 7. The inner side wall of the swivel 18 is located inside the feed barrel 7 and a stirring blade 19 is fixed thereto. The rotating motion of the stirring blade 19 can cause the raw materials to be continuously turned over in the feed barrel 7, ensuring that the raw materials are evenly dispersed and avoiding excessive local accumulation and clogging of the feed channel. The stirring blade 19 can play a role of premixing, so that the plastic raw materials are mixed under the action of stirring, providing a better foundation for the subsequent mixing and plasticizing process of the auger rod 4, thereby improving the mixing efficiency and quality.

[0022] Reference Figure 4 A plurality of tooth grooves are provided on the upper surface of the swivel 18 , and the swivel 18 is meshed with the fourth gear 17 through the tooth grooves. When the fourth gear 17 rotates, the swivel 18 can be rotated.

[0023] Reference Figure 2 The outer surface of the piston 9 fits with the inner surface of the feed barrel 7 to prevent the plastic particles from falling from the gap. A heating unit is provided inside the auger rod 4, and the heating unit heat-melts the plastic particle material entering the injection barrel 1.

[0024] Working principle: When in use, plastic granule raw materials are added into the hopper 8, and are fed and stirred at intervals by the feed barrel 7, and then enter the injection barrel 1. Finally, they are pushed by the hot melt and extrusion of the auger rod 4, and discharged from the left port of the injection barrel 1 into the automobile decorative parts mold for shaping. When the motor 3 is running, the auger rod 4 rotates, and the crank 12 is rotated under the sequential transmission of the first gear 5 and the second gear 6, so that the piston 9 is raised and lowered under the linkage of the rotating sleeve 13 and the connecting rod 14. When the piston 9 rises out of the feed barrel 7, the piston 9 no longer blocks the top opening of the feed barrel 7, and the raw material particles are able to enter the inside of the feed barrel 7. At the same time, when the crank 12 rotates, the third gear 16 and the fourth gear 17 drive the swivel 18 and the stirring blade 19 to rotate, and the stirring blade 19 stirs the falling raw materials to avoid blockage and premixing.

[0025] The above describes an exemplary implementation of an automobile decorative parts injection molding machine provided by the present disclosure with reference to a preferred embodiment. However, it will be understood by those skilled in the art that, without departing from the concept of the present disclosure, various variations and modifications may be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure may be combined in various ways without exceeding the scope of protection of the present disclosure, which is determined by the appended claims.
