[0045] The working principle of this utility model is as follows:
[0046] In actual production, the patterned film is first placed in the corresponding position of the forming component 5 inside the patterned film. Then, the hydraulic cylinder 17 is activated, and the hydraulic cylinder 17 pushes the forming slide 13 to slide on the limiting side frame 18, so that the two forming slides 13 move closer to each other, and the spliced forming part 4 closes. At this time, the cup body forming cavity 14 and the cup body forming cylinder 10 cooperate to form the cavity of the cup body, and the handle forming groove 15 is ready to form the handle.
[0047] Next, the injection mainboard 20 controls the injection tube 21 to inject molten plastic into the mold cavity through the cup bottom molding block 19. The plastic flows in the cavity, filling the molding space of the cup body, cup holder, and handle. Due to the precise fit between the cup body molding part 8 and the spliced molding part 4, the cup holder molding part 9 and the cup bottom molding part 6, and the design of structures such as the frustum sealing transition surface 11 and the arc transition surface 122, the smooth flow and molding of the plastic are ensured, avoiding leakage and molding defects.
[0048] After injection molding is completed, the mug is cooled for a period of time until it solidifies. Then, the hydraulic cylinder 17 is restarted to make the molding slide 13 slide in the opposite direction, and the spliced molding part 4 is opened so that the molded mug can be taken out.
