摘要： Provided are a blow molding mold, a blow molding method, and a method for manufacturing a molded article that enable the thickness of a deep drawn portion to be sufficiently maintained when blow molding a molded article in which the deep drawn portion is arranged adjacent to the weld portion of a parison. The blow molding mold and blow molding method form a molded article having: a weld portion formed by welding the inner surface of the parison; and a deep drawn portion arranged in the proximity of the weld portion. The blow molding mold is provided with a first mold and a second mold that form the weld portion by clamping. The second mold is configured from: a first split mold having a mold surface for forming the weld portion and a mold surface that constitutes a part of a deep draw recess for forming the deep drawn portion; and a second split mold having a mold surface that constitutes the remaining section of the deep draw recess. After blow molding, the deep drawn portion is cut at the mid point in the depth direction to form an opening, and the molded article is completed.
摘要翻译：本发明提供一种吹塑模具，吹塑成型方法和制造模制品的方法，当将深拉伸部分邻近于其的模塑制品吹塑成型时，能够充分保持深拉伸部分的厚度型坯的焊接部分。吹塑模具和吹塑成型方法形成模制品，其具有：通过焊接型坯的内表面而形成的焊接部分; 以及布置在焊接部分附近的深拉部分。吹塑模具具有通过夹紧形成焊接部分的第一模具和第二模具。第二模具由以下部件构成：具有用于形成焊接部的模具面的第一分割模具和构成深拉伸凹部的一部分的模具表面，用于形成深拉部分; 以及具有构成深拉凹槽的剩余部分的模具表面的第二分模。吹塑后，在深度方向的中点切割深拉部，形成开口，成型品完成。
