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

濕紙塑模具結構 Wet paper mold structure

本創作關於一種濕紙塑模具結構，特別是應用於溼紙塑產品的成型技術。 This work is about a wet paper mold structure, especially for the forming technology of wet paper and plastic products.

在現有溼紙塑產品的成型技術的撈紙漿製程中，漿槽用於儲存紙漿，紙漿的成分包含如植物碎片、各種纖維、水及其他原料等等，接著利用一模具下降浸入該漿槽中，再從該漿槽中上昇撈起紙漿以在該模具上形成一濕紙胚體或一紙塑成品，但在現有技術中，當該濕紙胚體或該紙塑成品自該模具脫模時，該濕紙胚體或紙塑成品的結構，特別是其外形，可能因沾黏於該模具上而產生損壞或不美觀的問題。因此，在另一現有技術中，係在模具上設置有貫孔，然而因為貫孔的設計問題，雖然解決了大部分區域的脫模問題，卻也使貫孔的部位可能因為受力不均勻而產生損壞。 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.
