Abstract

PURPOSE:To enable to obtain a desired shape inspite of having undercut shapes in many directions by setting an independent slide core moving in many directions on the slide core capable of handling reference undercuts. CONSTITUTION:The slide cores 4, A are moved by the cylinder 6 on the slide cores 5, B, then, the slide cores 5, B are moved by the pin 3. By this method, even is undercut section in two directions shown by A-B in the figure can be processed. In this manner, injection molded pieces having undercuts in many different directions can be injection-molded without changing the shape to obtain the desired shape of the molded piece.

Description

【発明の詳細な説明】 産業上の利用分野 本発明は、樹脂成形品の成形において利用される射出成
形金型に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an injection mold used in molding resin molded products.

宜上第３図に示すように、アンダーカット部を一方向に
のみそろえだ形状として射出成形金型を製作していた。Conventional technology In conventional resin molding molds, A and B as shown in Fig. 2 are used.
When injection molding a molded product 10 that has undercuts in different directions, the undercut cannot be treated, so for convenience, the injection mold is made so that the undercuts are aligned only in one direction, as shown in FIG. was producing.

う問題があった。2 - Problems that the invention aims to solve: If there are undercuts in many different directions in a resin molded product, the undercut cannot be processed by closing the mold or opening the mold during injection molding. This is because, therefore, the solution was to change the shape of the mold. However, this poses a problem in that the intended shape of the molded product cannot be obtained.

そこで、本発明は金型を改良することにより、多方向に
アンダーカット形状があっても、その本来の目的形状が
得られるようにすることを目的としだものである。Therefore, the object of the present invention is to improve the mold so that even if there are undercut shapes in multiple directions, the original intended shape can be obtained.

準となるアンダーカットの処理のできる３″−・ 方向のスライドコアＢ上に多方向に移動する別なスライ
ドコアＡを取シ付けているので、型締め。Function: Even when there are undercuts in multiple directions, another slide core A that moves in multiple directions is installed on top of the slide core B in the 3" direction, which can handle the undercuts as a reference. Because of this, the mold is tightened.

ライドコアを移動させることが可能である。When opening the mold, it is possible to move the slide core A attached to the reference slide core B, and then move the reference slide core further.

この結果、多方向にアンダーカット形状のある成形品が
スムーズに成形できる。As a result, molded products with undercut shapes in multiple directions can be molded smoothly.

実施例 以下、本発明の一実施例を添付図面にもとづいて説明す
る。Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

第１図は本発明に用いる金型の主要部の断面を示す。FIG. 1 shows a cross section of the main part of the mold used in the present invention.
