[0022] Specifically, through the arrangement of the water inlet conduit 3 and the water outlet conduit 4, it is convenient for water to enter and exit.

[0023] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, a plastic water cup mold structure of the present utility model, on both sides of the inner wall of the upper mold base 9, T-shaped sliding grooves 10 are provided.
