Claims

[Scope of utility model registration request]

(1) A large number of through holes are drilled in the corners of the bottom plate that is integrated with the core.
The bottom plate of the outer frame wooden mold and the bottom plate of the core define a chamber that communicates with the supply and exhaust means, and a film sheet placed inside the wooden mold is applied to the chamber by applying negative pressure to adsorb the foaming stock solution, which generates heat through a chemical reaction. A packaging cushioning material molding device that injects a film sheet into a wooden mold that has adsorbed it, and then applies pressurized fluid into the chamber using the same supply/exhaust means when demolding.

(2) The utility model registered in claim 1, in which the upper ends of the plurality of spacers supporting the core are provided slightly lower than the upper edge of the outer wooden mold so that a cardboard board can be placed thereon. Molding equipment for packaging cushioning materials.
