Abstract

Provided is a method for producing a molded body, with which it is possible to improve shapability of a resin sheet. The present disclosure provides a method for producing a molded body, the method comprising: a hanging step, a shaping start step, a welding step, and a formation step. In the hanging step, first and second resin sheet formation devices hang first and second resin sheets, respectively. In the shaping start step, shaping of the first resin sheet to a first mold is started in a state where a slide part protrudes from the first mold toward a second mold. In the welding step, the first resin sheet positioned at the tip of the slide part is welded to the second resin sheet by closing the first and second molds. In the formation step, a first wall part and an inner rib constituted by the first resin sheet and a second wall part constituted by the second resin sheet are formed by blowing air between the first and second resin sheets in a state where the slide part is housed in the first mold.

Abstract

Provided is a technique capable of reducing circumferential non-uniformity of the wall thickness of a preform formed by direct blow molding. The present invention provides a method for manufacturing a preform for biaxial stretch blow molding, the method comprising a blow molding step. In the blow molding step, a molded body having a preform constituent part that constitutes the preform is molded by blow molding a cylindrical parison in molten state using a mold unit. The preform is provided with a protruding seal part that protrudes from the bottom part of the preform. The mold unit is provided with first and second molds that are configured to be openable and closable. The parison is supplied between the first mold and the second mold. The first mold is provided with a first cavity. The second mold is provided with a second cavity. The first and second cavities are combined to form the outer surface of a cavity having a shape corresponding to the outer surface of the molded body. The mold unit is provided with a compression part. The compression part is configured to form a portion that becomes the protruding seal part, by compressing and sealing the parison between the first and second molds. In the blow molding, the parison comes into contact with the first mold prior to the second mold. In a bottom part formation part of the cavity that forms a portion that becomes the bottom part of the preform, the volume of the first cavity is greater than the volume of the second cavity.

Abstract

Provided is a panel manufacturing method provided with an extrusion step, a shaping step, an insert step, and a mold-closing step. In the extrusion step, a first resin sheet and a second resin sheet are extruded between a first die and a second die, the second resin sheet being positioned between the first resin sheet and the second die. In the shaping step, the first resin sheet and the second resin sheet are respectively shaped along the respective cavity surfaces of the first die and the second die. In the insert step, a foam body is positioned between the first resin sheet and the second resin sheet. In the mold-closing step, the first die and the second die are closed. The second die is provided with a convex ridge forming a hinge part, the tip of the convex ridge being provided with a first protrusion and a second protrusion corresponding to the first hinge and the second hinge, and a groove that corresponds to an intermediate part and that is positioned between the first protrusion and the second protrusion. In the mold-closing step, the first resin sheet, the second resin sheet, and the foam body are sandwiched and compressed between the first mold and the tip of the convex ridge, whereby the hinge part is formed. Where the depth of the groove is represented by Dg and the thickness of the second resin sheet is represented by Ts2, the value of Dg/Ts2 is 1.5 to 3.
