In order to achieve the above purpose, the technical scheme of the utility model is as follows: an injection mold for charging pile parts comprises a mold core; an injection molding cavity is arranged on the mold core; a glue injection port is formed in one side of the injection molding cavity; an electric heating rod is arranged on the other side opposite to the glue injection port; the electric heating rod is positioned in the mold core; the electric heating rod is parallel to the bottom of the injection molding cavity where the electric heating rod is located; cooling water channels with L-shaped structures are arranged on two sides of the electric heating rod; the cooling water channels are arranged along the length direction of the electric heating rod.

As a preferred scheme of the utility model, the water inlet of the cooling water channel is positioned at the bottom of the mold core; and the water outlets of the cooling water channels are positioned at two sides of the mold core.

As a preferred scheme of the utility model, a movable insert is arranged on the mold core; the movable insert is positioned at the position of the electric heating rod; the electric heating rod is positioned in the movable insert.

As a preferred scheme of the utility model, the movable insert is made of beryllium copper.

As a preferred scheme of the utility model, a plurality of electronic thermometers are arranged on the mold core; the electronic thermometers are distributed around the electric heating rod.

Through the technical scheme, the utility model discloses technical scheme's beneficial effect is: the utility model has the advantages of simple and reasonable structure, ingenious add the electrical heating stick on mould benevolence, improve with low costsly, adaptability is good, and the weld mark problem of solution product that can be fine has improved injection moulding product's surface quality and yields greatly, excellent in use effect.
