The following description of the various embodiments is set forth to illustrate the specific embodiments The directional terms mentioned in this creation, such as "upper", "lower", "before", "after", "left", "right", "inside", "outside", "side", etc., are only references The direction of the schema. Therefore, the directional terminology used is used to describe and understand the creation, and is not intended to limit the creation.

Refer to Figures 1 and 2. Figure 1 depicts a creation according to the present A perspective view of the first and second molds in the wet paper forming mold assembly of the first preferred embodiment. 2 is a cross-sectional view of a wet paper forming mold assembly 100 in accordance with a first preferred embodiment of the present invention. The wet paper forming mold assembly 100 has a main structure including a first mold 130, a second mold 140, a first web 160 and at least one suction device 190. In the present embodiment, the assembly 100 is for cooperating with a slurry tank 175 containing a pulp slurry 177, wherein the first mold 130 is immersed in the slurry tank 175, thereby causing the first mold 130 to The pulp slurry 175 is taken up in the slurry tank 175 to form a wet paper plastic body 170 on the first mold 130, and then pressure is applied to mold the first mold 130 and the second mold 140. The first mold 130 is pressed. The wet paper blank body 170 between the second mold 140 is stamped into a paper-plastic article.

The first mold 130 has a first side 135, at least one groove 110 and at least one first through hole 120, wherein the at least one groove 110 and the at least one first through hole 120 are formed on the first side 135, wherein the at least one first through hole 120 is further distributed around the at least one groove 110 or on the inner wall surface for before the first mold 130 and the second mold 140 are clamped to form a paper-plastic article. Water and/or water vapor in the wet paper body 170 is discharged.

The second mold 140 has a second side 145 and the second side 145 outwardly forms at least one pair of bumps 150 that should be at least one recess 110.
