I-shaped post insulator injection molding mold

The invention provides an I-shaped post insulator injection molding mold, and belongs to the field of insulator manufacturing. The forming die comprises two half dies, each half die is provided with a sheath cavity used for arranging an I-shaped core rod to form a sheath and an umbrella skirt cavity communicated with the sheath cavity to form an umbrella skirt, and the sheath cavities and the umbrella skirt cavities on the two half dies jointly define a die cavity; the half dies are provided with protrusions, the sheath cavity comprises two extending-in grooves and a communicating space, the two extending-in grooves are located in the two sides of the protrusions and used for allowing a pair of side wing plates of the I-shaped core rod to extend in respectively, the communicating space right corresponds to the protrusions and is communicated with the two extending-in grooves, and at least one half die is provided with a runner communicated with the sheath cavity or the umbrella skirt cavity. The mold is match
