Abstract
The present invention provides a method for manufacturing insert molded products, a mold for insert molding, and an insert molded product that enable the proper assembly of a metal collar into a resin molded part. [Solution] The insert molded product manufacturing method comprises: an insert step (step S1) in which a metal collar 10 is placed in a first mold 100; a clamping step (step S2) in which the second mold 200 and the first mold 100 are clamped together, thereby pressing the opening edge of the cylindrical portion on the second mold 200 side outward from the inner circumferential surface side by a pressing projection formed to protrude radially outward from the outer circumferential surface of the insertion portion, thereby forming a locking projection on the outer circumferential surface 1 of the cylindrical portion 11 corresponding to the opening edge; and a molding step (step S3) in which resin is filled into the cavity formed around the cylindrical portion 11 by the first mold 100 and the second mold 200 that were clamped together in the clamping step (step S2).
