Claims

[Scope of utility model registration request]

In a device that molds a product of a predetermined shape by injecting molten resin into a predetermined space formed on the overlapping surface of a fixed mold and a movable mold, there is an upper edge that is overlapped vertically directly below the fixed mold. An ejector plate and a lower ejector plate are provided, and the upper ejector plate is provided with an ejector pin for separating the unnecessary parts from the product after injection molding, and the lower ejector plate is provided for removing the unnecessary parts. An ejector pin is provided to release the separated product from the fixed mold.
An injection molding apparatus characterized in that the pressing of the upper ejector plate and the pressing of the lower ejector plate are performed in two stages using a single ejector rod.
