In order to achieve the above object, the utility model provides a following technical scheme: the lining ring positioning injection molding structure comprises a first injection molding part, a second injection molding part, a mold insert and a metal lining ring, wherein a plurality of clamping rings are arranged at the top end of the inner surface of the metal lining ring, and a clamping groove matched with the clamping rings is formed in one side, close to the metal lining ring, of the second injection molding part.

Optionally, the second injection molded part is located in a gap formed by the mold insert and the metal gasket.

Optionally, the metal collar is located within the first injection molded part.

Optionally, the mold insert is located within the metal collar.

Optionally, a plurality of the snap rings are integrally formed with the metal gasket.

Optionally, a plurality of the clamping rings are vertically distributed at equal intervals.

The utility model discloses a technological effect and advantage:

the utility model discloses a be equipped with the joint ring in the metal junk ring, can strengthen the firmness that second injection molding and metal junk ring are connected, avoided the second injection molding to drop from the metal junk ring, structural design is reasonable, simple and practical.
