Abstract: PURPOSE:To reduce hazards of an explosion and fire, by a method wherein a chamber filling and foaming raw materials and a chamber solidifying them after the foaming are separated from each other and a suction filter sucking a hydrocarbon is installed into a blower route of the solidifying chamber. CONSTITUTION:A suction filter 22 comprised of a conductive fiber material and an active carbon suction material is installed into a circulation air path 21 and the suction filter 22 is earthed. In the fourth process 6, both stock solutions through a hydrocarbon stock solution storage tank 23 and polyol stock solution storage tank 24 of pentane or cyclopentane into which nitrogen gas is enclosed are mixed 25 up with each other. The stock solutions are supplied to a casting machine 28 through a piping path arriving at the casting machine 28 by storing in a work tank 26 and a piping path storing in a work tank 30 from an isocyanate stock solution storage tank 29 and arriving at the casting machine 28 by a pump 31. The final mixing is performed by the casting machine 28 and filled up into a space between a pair of walls. Hereby, density of the hydrocarbon in a cure chamber 20 can be lowered.

Abstract: PROBLEM TO BE SOLVED: To easily seize a presence place of a round curved surface and information on its round radius in a display of a three-dimensional shape on the basis of three-dimensional CAD data. SOLUTION: Discrimination is made on whether or not to be the round curved surface on respective surface information included in the three-dimensional CAD data (S22), and when discriminated as being the round curved surface, display color information is set on the basis of round curved surface division information for presetting a display color with every division of the round radius size of the round curved surface (S24), and when discriminated as being not the round curved surface, the preset other display color is set (S25), and the round curved surface is classified by the preset display color, and the three- dimensional shape is displayed (S27).

Abstract: PROBLEM TO BE SOLVED: To improve the appearance of a molding by concealing a cutting line to be invisible by cutting a part of a parison inside the corner part ridgeline of the molding by a cutting means installed in a specified mold in blow molding. SOLUTION: A parison extruded from a die is composed of a first resin layer and a second resin layer in the circumferential direction, the borderline of each resin is formed in the vertical direction of the parison. The parison is supplied into a mold device in which molds 16, 17 are opened and blow- molded with mold clamping, and by the collaboration between a cutting means 21 and the mold 17 which are contacted with each other, the borderline part 13 between areas of different kinds of resins is cut. Since part of the parison can be cut inside the ridgeline 12 of the corner part of a molding 3, a cutting line 13 can be positioned on a specified wall surface side excluding the ridgeline 12 of the molding. For example, when the molding is used as a door main body 3 for a refrigerator, the cutting line 13 can be formed on the back side which can hardly be seen to improve the appearance of the door.

Abstract: PROBLEM TO BE SOLVED: To arrange/form a borderline without cutting a part of a parison by a method wherein, in blow molding with a mold clamped, a part of the parison in the mold is pushed inside by a pushing means installed in the mold, and a mew resin borderline is formed in a molding. SOLUTION: A parison extruded from a die constitutes a first resin layer 3 and a second resin layer 4 in the circumferetntial direction and supplies each borderline 5a into a mold device 8 in which molds 10, 11 are opened in agreement with each pushing means 15 located at receiving position. With the advance of both pushing means 15 while the molds being clamped and the parison being blow-molded, an air controller is actuated to a suction side. The resin borderline of the parson is pushed inside the parison by the projection of each pushing means 15, a borderline part 17 is pushed surely without dislocation to suck the parison, and even after the pushing means 15 being extracted, a new borderline is formed on the surface of a molding. There is no need to cut the parison, improving workability.
