摘要： On the basis of the controllability of wall thickness distribution of a mold product by a preform shape, the number of fabrication steps and the cost required for a design and trial formation of a preform forming metal mold are reduced by designing a preform shape such that a thickness distribution of the preform leads a wall thickness distribution of an aimed mold product to thereby obtain a mold product having an ideal rigidity and stability thereof.

摘要： 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.
摘要翻译：当使用金属模具模制熔融塑料时，在金属模具打开之前必须经过足够的冷却时间，但是该冷却时间限制了每单位时间的生产。如果在没有充分冷却的情况下打开金属模具，则塑料通过热收缩而发生显着的变形。如果可以估计这种变形并且金属模具被设计成允许预期的变形，则尽管缩短了冷却时间，但是可以生产具有等于设计尺寸的形状的模制件。有限元法用于获得变形。还可以考虑由于当模制件充满其液体内容物时产生的静水压力而导致的变形，进行模具设计。此外，对于包括层叠结构的模内标签容器的一部分，由于热收缩而导致的变形不被估计为未被施加模内标签的容器。在这种情况下，我们有一种在添加与该标签的材料相关的参数之后模拟变形的方法，所述参数至少包括其热导率和线性膨胀系数。热导率变形模拟采用有限元法。单位时间的生产可以增加，金属模具设计可以独立于经验进行。

摘要： In order to provide a mold of a shape which has been designed to take into account the deformation occurring during the cooling process, the mold cavity is formed so that the external volume of a molded product obtained by blow molding in this cavity ultimately shrinks by a prescribed percentage of the volume of the mold cavity, and so that in the region of maximum shrinkage the external size of the body portion of the molded product shrinks by a prescribed percentage of the size of the corresponding portion of the mold cavity.
