The Mold Core and the cavity that constitute the part of the molded article that becomes an undercut are divided, and then designed and fabricated.

• The Removable Mold Core Inserts that are prepared by dividing the mold are taken out from the mold along with the molded product at the time of ejecting the molded article.
• The Removable Mold Core Insert is removed from the molded article by a manual operation.
• The Removable Mold Insert is installed in the mold manually at the time of the next molding.
• In other words, with a Removable Mold Core Insert structure, it is not possible to carry out continuous injection molding, and the method is that of forming the undercut shape semi-automatically using manual operations additionally.
• There are also some cases in which the Removable Mold Core Insert is pushed out from the mold by an ejector pin.
• In order to position the Removable Mold Core Insert, a key structure or a knock pin structure is used in some cases.
• There are cases in which the molding is done after pre-heating the Removable Mold Core Insert.
• There is also the method of molding which makes the semi-automatic molding more efficient by preparing two Removable Mold Core Inserts, and inserting them alternately into the mold.
• In order to ensure that the direction of inserting the removable insert is not mistaken, there is also the technique of using a direction determining structure.
• The key point is to design the escape and the clearance so as to make it easy to install and remove the removable inserts.
• There is also the management aspect of provisionally preparing the trial mold with a removable insert structure, thereby obtaining time for developing a mold structure such as the slide core structure that can permit continuous molding.
