Abrégé

Provided is a mold manufacturing method with which the requirement of a wide variety of products in a small lot can be satisfied. A cutting step includes forming, through cutting, mold matching surfaces in respective upper and lower molds and forming, through cutting, cavities C1 and C2 in the respective upper and lower molds with the mold matching surfaces being references. A mold matching step includes: measuring at least three points PU1 to 3 that are not located on a same straight line and that are located on the mold matching surface of the lower mold placed on a placement surface; causing recognition of Z coordinates of these respective points; measuring at least three points PL1 to 3 that are not located on a same straight line and that are located on the mold matching surface of the upper mold gripped by a gripping arm; causing recognition of Z coordinates of these respective points; and subsequently performing mold matching with the mold matching surfaces SmU and SmL of the upper and lower molds being oriented to be kept parallel to each other.

Abrégé

The present invention provides a heat-insulating container box which, by having a simple structure, being lightweight, having an inner surface which does not get dirty, and being equipped with a door-opening/closing structure which is easily operable via wing doors and side flaps, solves the problems inherent to conventional heat-insulating container boxes of having a complicated structure, entailing a burdensome opening/closing operation, and having an inner surface which gets dirty. Specifically, the provided heat-insulating container box 100 is provided with two side flaps 17, 18 and two wing doors 15, 16 which are rotatably attached at both end sections of an upper plate 14 of a body 10. Thus, the heat-insulating container box 100 is configured so as to comprise opening/closing doors (wing doors and side flaps) which are split into two parts, and the side flaps 17, 18 each have a structure which opens by moving below a bottom plate 11 while keeping the outer surface of the heat-insulating container box 100 closed.

Abrégé

Provided is a method for manufacturing molds with which it is possible to accommodate small lots and a wide variety of products.　In a cutting step, a mold matching surface is cut and formed on each of upper and lower molds, and a cavity C1, C2, is cut and formed on each of the upper and lower molds respectively using the mold matching surfaces as reference. In a mold matching step, at least three points PU1-3 that are not located on the same straight line on the mold matching surface of the lower mold placed on a placement surface are measured, and the z-coordinates of the respective points are recognized. At least three points PL1-3 that are not located on the same straight line on the mold matching surface of the upper mold gripped by a gripping arm are measured, and the z-coordinates of the respective points are recognized. Mold matching is then carried out in an attitude in which the mold matching surfaces SmU, SmL of the upper and lower molds are kept parallel.
