[0006] Preferably, the upper die is located above the ejector head and is provided with an ejector rod and an ejector plate in sequence, and the outer diameter of the edge of the ejector plate is matched with the outer diameter of the opening end of the inner shell of the water cup assembly.

[0007] Preferably, an elastic member is further provided between the positioning block and the base.

[0008] Preferably, the positioning block further comprises a limiting portion disposed below the guide portion, for limiting the positioning block from escaping from the limiting hole.

[0009] Preferably, the elastic member is a spring.

[0010] Preferably, the lower mold also includes a lower mold sleeve located above the lower mold base, and the inner diameter of the lower mold sleeve is adapted to the outer diameter of the water cup assembly.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: by adopting the above technical scheme, a positioning head adapted to the special-shaped hole of the inner shell and a guide part adapted to the special-shaped hole of the outer shell are arranged on the lower die, when placing the outer shell and the inner shell, the special-shaped holes of the outer shell and the inner shell can be positioned together by the guide part and the positioning head; and the positioning block is arranged to slide up and down in the cavity of the lower die base, when placing the outer shell, the special-shaped hole of the outer shell passes through the guide part and abuts against the bottom surface of the lower die base, when placing the inner shell, the special-shaped hole of the inner shell passes through the positioning head and abuts against the limit step, and is pressed against the limit step by the top head of the upper die, and the upper die can be pressed downward by the downward sliding of the positioning block until the inner shell is pressed into the outer shell, completing the matching positioning and press-fitting to form the water cup assembly A.

[0012] A further beneficial effect is that the upper die is also adapted to the outer diameter of the opening end of the inner shell by setting a top plate, and the top plate can be pressed down to contact the opening end of the inner shell synchronously, so that the press-fitting process is more stable, the force on the inner shell is more uniform, and the inner shell is not easily deformed.

[0013] A further beneficial effect is that an elastic member, such as a spring, arranged between the positioning block and the base can make the positioning block be located at the highest point to receive the inner shell when the mold is opened by default, and after the water cup assembly is press-fitted, the water cup assembly can be demoulded under the action of the restoring force of the elastic member, thereby facilitating the removal of the water cup assembly; and the limiting portion of the positioning block can limit the positioning block from falling out of the limiting hole.

[0014] A further beneficial effect is that by providing the lower die sleeve, the outer shell and the inner shell of the water cup assembly are guided when placed on the lower die, thereby preventing them from tilting and ensuring that they stand upright, which is convenient for press-fitting production.
