Abstract

A molding structure for forming wet paper shape product is introduced, which comprises a first mold and a second mold. The first mold comprises a first plane, a second plane, and a plurality of through holes is disposed on the first mold. A second mold comprises a third plane which faces to the first plane of the first mold, and a space formed between the first plane and the third plane is used to form the wet paper shape product. Each of the first through holes forms an external first opening on the first mold. A first cutting plane is formed between the first opening and the first plane. An included angle is formed between the first cutting plane and the first plane. A diameter of the first opening is larger than a diameter of the first through hole. With arrangement of the external openings having the included angles on the first through holes, a damage rate of the wet paper shape product is decreased while being separated from the molds.

Description

Wet paper mold structure

This work is about a wet paper mold structure, especially for the forming technology of wet paper and plastic products.

In the pulping process of the existing wet paper-plastic product molding technology, the slurry tank is used for storing pulp, and the components of the pulp include, for example, plant fragments, various fibers, water and other raw materials, etc., and then dipped into the slurry tank by using a mold. And lifting the pulp from the sump to form a wet paper body or a paper product on the mold, but in the prior art, when the wet paper body or the paper product is released from the mold At the time, the structure of the wet paper body or the paper-finished product, particularly its shape, may be damaged or unattractive due to sticking to the mold. Therefore, in another prior art, a through hole is provided in the mold. However, because of the design problem of the through hole, although the problem of demolding in most areas is solved, the part of the through hole may be uneven due to force. And it caused damage.

Therefore, there is a need to provide a wet paper mold structure to solve the above problems.

In order to solve the above problems, the purpose of the present invention is to propose that a wet paper mold structure can be used not only for rapid drying and molding of a wet paper plastic semi-finished product and/or a wet paper plastic final product, but also does not destroy the wet paper plastic when demolding. The structure of the semi-finished product and/or the final product of the wet paper.

To achieve the above creative purpose, the mold structure includes a first mold and a second mold.

The first mold has a first plane, a second plane and a plurality of first through holes distributed on the first mold. The second mold has a third plane facing the first plane of the first mold, and the first plane and the third plane are used to form a wet paper. Each of the first through holes defines a first outer opening on the first mold, and a first cut surface is formed between the first through hole and the first through hole, the first cut surface and the first flat surface Forming a first angle, and the diameter of the first opening is greater than the diameter of the at least one first through hole.

In a preferred embodiment, the first section is one of a curved surface, a stepped shape, and a flat surface.

In a preferred embodiment, the plurality of first through holes are distributed in the first plane.

In a preferred embodiment, the plurality of first through holes extend from the first plane to the second plane.

In a preferred embodiment, the first mold further forms at least one groove, and the plurality of first through holes are distributed on at least one groove wall of the at least one groove.

In a preferred embodiment, a plurality of second through holes are formed in the third plane of the second mold.

In a preferred embodiment, the third plane of the second mold further forms at least one protrusion to face the at least one groove, and at least one outer surface of the at least one protrusion forms a plurality of second through holes.

In a preferred embodiment, each of the second through holes has a second outer opening, and the second opening and the second through hole form a second cut surface, the second cut surface and the third plane A second angle is formed between the diameters of the second openings and the diameter of the corresponding second through holes.

The present invention reduces the probability of damage of the wet paper during demolding by providing external first and second openings with angles at the first through hole and the second through hole, respectively.

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., just refer to 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.

1 is a schematic view of a mold structure 100 in accordance with a preferred embodiment of the present invention. The mold structure 100 includes a first mold 110 and a second mold 120.

The first mold 110 has a first plane 140 , a second plane 150 , and a plurality of first through holes 130 distributed on the first mold 110 . The second mold 120 has a third plane 160 facing the first plane 140 of the first mold 110, and the first plane 140 and the third plane 160 are used to form a wet paper semifinished product or wet. The final product of paper and plastic. The first mold 110 defines a groove 170, and the plurality of first through holes 130 are distributed on at least one groove wall around the groove 170 and on the first plane 140. The third plane 160 of the second mold 120 has a bump 180 opposite to the recess 170. A plurality of second through holes 190 are formed on the third plane 160 of the second mold 120 and at least one outer surface of the bump 180. Depending on the application, a plurality of sets of the grooves 170 can be designed to cooperate with the bumps 180.

FIG. 2 is an enlarged side elevational view showing the first through hole 130 according to FIG. 1. Taking one of the first through holes 130 as an example, the first through hole 130 penetrates from the first plane 140 to the second plane 150. The first through hole 130 defines a first opening 134 on the first plane 140 of the first die 110. A first cut surface 136 is formed between the first opening 134 and the first through hole 130. A first angle 132 is formed between the first slice 136 and the first plane 140 such that the diameter D2 of the opening 134 is greater than the diameter D1 of the at least one first through hole 130.
