Abstract
A cabinet forming a casing for electronic equipment molded integrally by blow molding, includes a first panel formed to a substantially uniform thickness, a second panel formed to a thickness substantially equal with that of the first panel, and a corner portion formed to a thickness substantially equal with that of the first panel and the second panel and having a cylindrical hollow portion.
Claims9
A cabinet forming a casing molded integrally by blow molding, comprising:
- a first panel having an edge at one end and a continuous portion at an opposite end and formed to a substantially uniform thickness from the one end to the opposite end from a molding resin;
- a second panel connected to said continuous portion and formed to a substantially uniform thickness from one end to an opposite end, the thickness being substantially equal to that of the first panel from the molding resin;
- and
- a gas channel formed from the molding resin adjacent said continuous portion and formed to a thickness greater than the thicknesses of the first panel and the second panel, whereby a pressure of the resin is reduced at said gas channel so as to form a substantially uniform thickness in said first and second panels during the blow molding process.

A process for forming a casing by blow-molding comprising the steps of:
- forming a molded section for a first panel with substantially uniform thickness from an entrance to an end face opposite said entrance;
- forming a molded section for a second panel with substantially uniform thickness substantially equal to the thickness of the first panel from an entrance to an end face such that a longitudinal corner portion is formed between said first and second panel molded sections so as to be contiguous with and substantially parallel to the entrance of each of said first and second panel molded sections;
- forming a molded section for a gas channel adjacent the longitudinal corner portion and located proximate the entrances of the first and second panel molded sections so that the thickness of the gas channel is greater than the thicknesses of the first and second panels;
- introducing a molding resin into mold sections forming the corner section and said gas channel;
- and
- forcing the molding resin into mold sections forming the entrances of the first and second panel sections by pressure from a gas introduced into the mold section forming the gas channel, whereby the molding resin flows into mold sections forming the end faces of the first and second panel molded sections and forms the first and second panel molded sections completely with a substantially uniform thickness.
