Abstract

Disclosed is an insert molding apparatus employed to form a plastic product with an insert. The insert has an inserting unit and an extending unit. The insert molding apparatus comprises a cope plate, a lower die and a holding mechanism. The cope plate is formed with a cavity. The extending unit dips into the cavity. The holding mechanism is installed on the lower die to hold the extending unit of the insert. When the insert molding apparatus of the present invention is opened, the holding mechanism can hold the extending unit of the insert to prevent the plastic product sticking to the cope plate. Accordingly, it is capable to prevent the plastic product crushed when the insert molding apparatus is closed again.
