Insert mold structure for shower head

The invention provides an insert mold structure for a shower head, comprising a mold insert used for molding the external structure of the shower head and insert pins used for molding a water outlet of the shower head, wherein each insert pin comprises a main body, a hang block, a first molding part and an insert pin end, wherein the hang block is arranged at the upper end of the main body, the first molding part arranged at the lower end of the main body is used for molding the water outlet, the insert pin end is connected with the main body, and the axis of the insert pin end and the axis of the first molding part are in the same line; the mold insert comprises a body part, a second molding part and an insert auxiliary part, wherein the second molding part is arranged inside the body part, and the insert auxiliary part and the insert pin end form an oblique angle to secure the insert auxiliary part and the insert pin end to be not close, so the mold is easy to exhaust and has little wear; and the acute angle between the insert auxiliary part and the insert pin end enables thin flash at the insert pin end to easily fracture when the mold is opened, thus saving manual deflashing in post process.
