The turntable 112 is connected to the servo motor 111 by a rotating shaft, and the servo motor 111 provides power for the rotation of the turntable 112.

[0031] Please refer to this carefully. Figure 1 and Figure 2 The bottom of the material tube 201 is equipped with a slider, and both ends of the top of the injection module 2 are equipped with slide rails to facilitate the position adjustment of the material tube 201 and the heating tube 204.

Both ends of the machine cover 301 are equipped with movable doors.

[0032] Working Principle: In use, resin raw material granules are first added to the material pipe 201 through the discharge port. After being heated and melted by the heating tube 204, the heating tube 204 is driven forward by the hydraulic motor 203 to the injection station 101, where it connects with the injection port of the preform mold for injection molding. The raw material is then injected. The hydraulic cylinder 103 drives the lifting platform 114 to connect the turntable 112 with the preform mold. Simultaneously, the hydraulic motor 202 drives the melted raw material into the preform mold. After preform molding, the hydraulic cylinder 103 moves the turntable 112 upwards, carrying the preform out of the mold. Then, the servo motor 111 rotates the preform into the temperature-controlled chamber. At position 104 of the core assembly, the temperature regulating cylinder of the temperature regulating cylinder assembly 105 is raised to the preform position, and the temperature regulating inner core of the temperature regulating inner core assembly 104 is moved into the preform to heat and regulate its temperature. After adjusting to the set temperature, the temperature regulating core of the temperature regulating inner core assembly 104 and the temperature regulating cylinder of the temperature regulating cylinder assembly 105 are returned to their original positions. Then, the preform is driven upward by the hydraulic cylinder 103 to carry it out. Then, the servo motor 111 drives the preform to rotate to position 102 of the injection molding station, and the preform is carried into the injection mold at position 102 of the injection molding station by the hydraulic cylinder 103. The second material or the second color material is added into the material tube 201 and heated through another set of heating tubes. 204 is heated and melted. Another hydraulic motor 203 drives the preform forward to the injection mold. Another hydraulic motor 202 injects the melted material into the injection mold. After the preform is formed, the hydraulic cylinder 103 drives the preform out. The servo motor 111 rotates the preform to the position of the temperature regulating cylinder assembly 106. The hydraulic cylinder 103 returns to the origin. The temperature regulating cylinder of the temperature regulating cylinder assembly 106 is moved to the preform position. At the same time, the temperature regulating inner core assembly 107 is moved into the preform to heat and adjust the preform temperature. After adjusting to the set temperature, the temperature regulating inner core assembly 107 and the temperature regulating cylinder of the temperature regulating cylinder assembly 106 are moved back to the origin. The hydraulic cylinder 103 drives the preform out. The preform is lifted to a set height, and the servo motor 111 drives the preform to rotate to the blow molding station 109. The hydraulic cylinder drives the preform downward to move it into the blow molding assembly 108. Then, the blow molding assembly 108 closes the mold, and at the same time, the blow molding station 109 drives the preform downward to the bottle mouth for blowing. After the bottle is formed, the blow molding assembly 108 and the blow molding station 109 return to the origin. The hydraulic cylinder 103 carries the formed bottle out to a set height, and the servo motor 111 rotates the formed bottle to the bottle exit station 110. The hydraulic cylinder 103 returns to the origin, and the bottle exit assembly 110 ejects the formed bottle. The above actions are repeated in six stations to achieve rapid blow molding processing.
