Abstract
A papermaking mold for producing a pulp molded article comprising a core of prescribed shape which has a plurality of holes for fluid passage interconnecting the outside and the inside and is made of an elastically deformable material and a fluid-permeable material which covers the outer surface of the core, the fluid-permeable material being capable of forming passages for a fluid in its thickness direction even when pressed and deformed.
Claims18
An apparatus for producing a pulp molded article, comprising:
- a female mold configured to include an impression;
- a mold configured to be fitted into the impression;
- and
- a pressing member,
- wherein the mold includes a core having a prescribed shape and including an elastically deformable material and a plurality of holes configured to interconnect an outside and an inside of the core, and a fluid-permeable material configured to cover the outside of the core and to enable fluid flow in a thickness direction during pressing and deformation, and
- wherein the mold is configured to undergo elastic deformation in conformity with the configuration of the impression when pressed by the pressing member, thereby filling a space in the impression.
