Problems solved by technology

[0004] However, in order to form the molded body described in this gazette, in the papermaking process, when the convex line is formed on the surface of the molded body, the dehydration mold and drying mold used in the subsequent dehydration process and drying process are formed on the same surface. The ridges correspond to fine slit-shaped ventilation grooves, and in order not to deform the easily deformable paper-making formed body in a wet state, especially the ridges on the outer surface, it is necessary to make the ridges Alignment with slot location for correct positioning, which is extremely difficult
On the other hand, in Japanese Patent Application Laid-Open No. 6-158599, although it is described that sand core vent holes are arranged on the drying mold as a discharge path for water vapor to improve drying efficiency, but in this drying mold, It is not possible to form narrow ridges
That is, since the convex portion tends to accumulate vapor during drying and easily causes a so-called steam explosion, it is difficult to form a high-density convex portion also on the front end (protruding end portion).

Embodiment Construction

[0036] Hereinafter, the present invention will be described according to its best embodiment with reference to the drawings.

[0037] figure 1 It is an exploded perspective view of the first embodiment of the drying mold of the present invention, Figure 2A with Figure 2B Respectively represent the side view from its dividing plane figure 1 Front and side sectional views of the drying mold shown.

[0038]The drying mold 1 of this embodiment is used to dry a fiber laminate in a wet state obtained by a pulp molding method. The drying die 1 is composed of a fiber laminate housing portion (hereinafter simply referred to as the housing portion) 10 and a manifold portion 20 . The housing portion 10 has a cube-shaped block 11 and plate-shaped flanges 12 extending horizontally from three upper ends of the block 11 . On the upper surface of the block 11, a concave drying part 13 of a shape obtained by fitting with the longitudinal half of the fiber laminate in a wet state formed ...

Abstract

A molded body formed with pulp mold having projected lines corresponding to a slit-shaped vent passage part, capable of being provided by paper-making / dewatering, using a paper making mold, a slurry having fibers dispersed in a liquid so as to obtain a three-dimensional fiber wetted laminated body, moving the laminated body to a dry mold having an inner surface with slit-shaped vent passage, and pressing and drying that laminated body.

Description

[0001] This application is a branch of the applicant Kao Corporation, the application number is 200310102836.4, the application date is August 4, 2000, and the title is "Molded body with convex part, drying mold for its production, production method and device" Application. technical field [0002] The present invention relates to a molded body having a convex portion, a drying mold for manufacturing the molded body, a method for manufacturing the molded body, and a manufacturing apparatus for the molded body. Background technique [0003] From the perspective of improving environmental pollution, pulp molded bodies are being used instead of plastic molded bodies. Such a pulp molded article can be produced, for example, by a method for producing a pulp molded article including the steps of supplying pulp slurry to the papermaking surface of a papermaking mold having an air passage, and sucking the pulp through the air passage. A papermaking process in which pulp is deposite...
