Description

Plastic cup processing device Technical Field The utility model relates to the field of bridge deck height difference adjustment, in particular to a plastic cup processing device. Background In the current society, plastic cups are widely applied to daily life of people, such as disposable plastic cups of street beverage shops, when the plastic cups are processed, molten plastic raw materials are generally injected into a die cavity of a die, and then the plastic cups are obtained, wherein the injection die is generally divided into an upper die and a lower die, the lower die is upwards moved to be combined with the upper die to manufacture the plastic cups, then the lower die is downwards moved with the plastic cups, firstly, the plastic cups are demoulded from the upper die, then the lower die is continuously downwards moved, and then the plastic cups are demoulded from the lower die, so that the die stroke is necessarily larger than the cup height in order to ensure that the plastic cups are separated from the die due to the longer cup body height, and the processing efficiency is low. Disclosure of utility model The utility model provides a plastic cup processing device which reduces the stroke of a die and improves the processing efficiency. The technical scheme adopted for solving the problems is as follows: The utility model provides a plastics cup processingequipment, includes outer cup mould in cup mould and symmetry lock in cup mould both sides, and the rim of a cup end of interior cup mould is fixed with the master seat, and two outer cup moulds are all rotated through the both ends of round pin axle with the master seat and are connected, when two outer cup moulds detain interior cup mould, the cooperation master seat constitutes a cup die cavity, be equipped with the pipe of moulding plastics on the master seat for with plastics through interior cup mould bottom central point put into the cup die cavity.
