[0038] Working principle: When in use, two servo motors 101 are turned on at the same time to drive two groups of electric push rods 103 to rotate relative to or opposite to each other through the fixed block 102. Multiple molds 105 and molds 114 are grouped in pairs. The sizes of each group of molds 105 and molds 114 are different, so milk tea cups of different sizes can be processed.

The sizes of the multiple hollow forming cores 120 are also different. The size of 20 corresponds to the same mold 105 and mold 2 114. The electric telescopic rod 116 drives the hollow molding core 120 to be embedded in the combined mold 105 and mold 2 114 through the U-shaped frame 117. The annular plate 123 can seal the top of the mold 105 and mold 2 114. An appropriate amount of molten plastic is injected into the mold 105 and mold 2 114 through the feeding funnel 122, and then the cooling machine 119 inside the hollow molding core 120 is turned on to cool and solidify the molten plastic. After the plastic is formed, the electric telescopic rod 116 and the two electric push rods 103 drive the hollow forming core 120, the mold 105 and the mold 2 114 to shrink, so that the formed milk tea cup falls through the discharge port 112 to the guide plate 113, and is transferred to the inside of the collection box through the guide plate 113. The outer surface of the hollow forming core 120 and the interior of the mold 105 and the mold 2 114 are coated with an anti-stick coating 121, which can prevent the plastic from sticking, facilitate the demoulding of the formed milk tea cup, and improve the processing efficiency.
