Description

ここに開示された空調装置用ドアの製造方法は、筒状部の内側を形成する棒状の内側金型（７３）と、内側金型に向かって突出しており、棒状の内側金型の外周面に沿った先端形状である凸部（１７１、１７２、２７２、３７２、４７２）を有して筒状部の外側を形成する外側金型（７１、７２）とを所定の位置に配置して金型を組み合わせる型締め工程と、型締めされた内側金型と外側金型との間に形成された空洞部（７６）に樹脂部材を射出する射出工程とを含み、型締め工程では、内側金型と外側金型の凸部とを接触させた状態で配置し、射出工程では、内側金型は、樹脂部材の射出により押される射出圧を受けるとともに、射出圧に対して抗するように内側金型を押し返す押圧力を凸部から受ける。 The manufacturing method of the door for an air conditioner disclosed here includes a rod-shaped inner mold (73) that forms the inside of the cylindrical portion, and an outer peripheral surface of the rod-shaped inner mold that protrudes toward the inner mold. An outer mold (71, 72) that has a convex portion (171, 172, 272, 372, 472) that is a tip shape along the outer surface and forms the outside of the cylindrical portion is placed at a predetermined position to form a mold. A mold clamping process for combining the molds, and an injection process for injecting a resin member into a cavity (76) formed between the clamped inner mold and the outer mold. The mold and the convex part of the outer mold are arranged in contact with each other, and in the injection process, the inner mold receives the injection pressure pushed by the injection of the resin member, and the inner mold resists the injection pressure. A pressing force that pushes back the mold is received from the convex portion.

Claims

In the manufacturing method of the door for air conditioners which has a cylindrical part (121),
A rod-shaped inner mold (73) that forms the inside of the cylindrical portion, and a convex portion (171) that protrudes toward the inner mold and has a tip shape along the outer peripheral surface of the rod-shaped inner mold. 172, 272, 372, 472) and an outer mold (71, 72) that forms the outside of the cylindrical portion and is placed at a predetermined position, and a mold clamping step for combining the molds;
An injection step of injecting a resin member into the cavity (76) formed between the clamped inner mold and the outer mold,
In the mold clamping step, the inner mold and the convex part of the outer mold are arranged in contact with each other,
In the injection step, the inner mold receives an injection pressure that is pressed by the injection of the resin member, and receives air pressure from the convex portion that pushes back the inner mold so as to resist the injection pressure. Manufacturing method of door for apparatus.
