Abstract: When a molten plastic is molded using a metal mold, sufficient cooling time has to elapse before the metal mold is opened, but this cooling time restricts the production per unit time. If a metal mold is opened without sufficient cooling, the plastic undergoes significant deformation by thermal shrink. If this deformation can be estimated and the metal mold designed so as to make allowance for the anticipated deformation, it will be possible to produce a molding with a shape that is equal to the design dimensions, despite shortening the cooling time. The finite element method is used to obtain the deformation. Mold design can also be performed taking account of the deformation due to the hydrostatic pressure that is produced when the molding is filled with its liquid contents. In addition, as for a portion of an in-mold labelled container which include lamination construction, the deformation due to thermal shrink is not estimated as a container which an in-mold label is not being applied. On this case, we have a method which is simulating deformation after adding parameters relating to the material of this label, said parameters including at least its thermal conductivity and coefficient of linear expansion. The thermal conductivity deformation simulation is by the finite element method. Production per unit time can be increased and metal mold design can be carried out independently of experience.

Abstract: When a molten plastic material is molded with a mold, it is necessary to open the mold after a sufficient cooling time but the amount of production per unit time is restricted by this cooling time. When a mold is opened without being cooled sufficiently, the plastic material thermally shrinks and is deformed greatly. In such a case, the deformation of the plastic material is grasped, and the mold is designed taking the deformation into consideration, whereby a molded product of designed dimensions and shape is obtained even when the cooling time is shortened. In order to grasp the deformation, a finite element method is used. The mold is designed considering the hydrostatic deformation of the molded product when a liquid material is placed in the product. In a method of designing a mold for molding a resin container, comprising the steps of molding previously estimating the deformation of a molded resin container due to the thermal shrinkage taken out from the mold, designing the mold with the estimation, and taking out the molded resin container from the mold before the resin sufficiently is cooled, in the case of a container having an in-mold label portion, the portion has a label-laminated structure, and therefore the deformation of the resin container due to thermal shrinkage cannot be estimated in the same manner as that of a resin container having no in-mold label portion. In such a case, a deformation simulation is carried out by adding parameters including at least the thermal conductivity and linear expansion coefficient to the data on the material of the label. The thermal shrinkage deformation simulation is carried out by a finite element method (FEM). This enables the amount of production per unit time to be improved, and the designing of a mold to be done not by experience.

Abstract: PROBLEM TO BE SOLVED: To obtain the aimed shape of a molding even when the cooling time in a plastic molding process is shortened by a method wherein a mold is formed on the supposition that the outer volume of the molding finally shrinks in the range of a specified percentage of the volume of the cavity of the mold.

In this case, when a HDPE(high density polyethylene) is employed as the thermoplastic resin, the mold l is formed on the supposition that the outer volume of the molding finally shrinks smaller than the volume of the cavity part of the mold l by 7.0-13.5%. Further, when a PP(polypropylene) is employed as the thermoplastic resin, the mold 1 is formed on the supposition that the outer volume of the molding finally shrinks smaller than the volume of the cavity part of the mold 1 by 5.8-8.5%.
