Problems solved by technology
[0003] The technical problem to be solved by the present invention is to provide an antenna rod injection mold and its injection molding method that can easily ensure concentricity. By rotating the injection rod, the glass fiber rod can be rotated until it is controlled and positioned by the positioning needle on the side of the sky and earth, so as to solve the problem of post-injection. Defects such as leakage of glass fiber rod and poor injection filling of antenna rod head

Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings.
[0021] Such as figure 1 and figure 2 As shown, a kind of antenna rod injection mold that is convenient to ensure concentricity includes a slider seat, and a plurality of molding inserts 3 are provided on one side of the slider seat, and a mold insert 3 is provided in the slider seat to match the molding inserts. Injection rod 4 with the same number of parts 3, one end of the injection rod 4 passes through the molding insert 3, and the other end passes through the slider seat, and the injection rod 4 can be opposite to the slider seat and the molding insert 3 rotates, and the molding inserts 3 are provided with injection runners 5 .
[0022] By extending one end of the injection rod to the outside of the slider seat, and setting it as a structure that can rotate relative to the slider seat and the molding insert, after fixing the fiberglass rod to the injection rod, ...

The invention discloses an antenna mast injection mold capable of conveniently guaranteeing the concentricity. The antenna mast injection mold comprises a sliding block seat, wherein a plurality of forming inserts are arranged on one side of the sliding block seat; injection molding rods of which the number is the same as that of the forming inserts are arranged in the sliding block seat; one endof each injection molding rod penetrates through the corresponding forming insert; the other end of each injection molding rod penetrates through the sliding block; the injection molding rods can rotate relative to the sliding seat and the corresponding forming inserts; and injection molding flow channels are arranged on all the injection molding rods. The invention further discloses an antenna mast injection molding method capable of conveniently guaranteeing the concentricity. Through the rotation of the injection molding rods, fiberglass rods can rotate along with the injection molding rodstill being controlled and positioned by sky-side and ground-side positioning needles, and then the defects that the fiberglass rods are exposed as well as the injection molding and filling effects onthe head parts of antenna masts are poor after the injection molding operation can be overcome.
Description
Background technique [0001] During the injection molding process of the antenna rod, because the glass fiber rod itself may have a certain degree of curvature, after it is fixed on the injection rod, the existing injection molding equipment cannot adjust the concentricity of it, so the glass fiber rod in the process technology If the center straightness cannot meet 100% probability, it will be positioned by the positioning needle on the sky and earth side, resulting in a certain probability of leakage of the glass fiber rod after injection molding or poor injection filling of the head of the antenna rod. technical field [0002] The technical problem to be solved by the present invention is to provide an antenna rod injection mold and its injection molding method that can easily ensure the concentricity, which belongs to the technical field of antenna rod processing. Contents of the invention [0003] The technical problem to be solved by the present invention is to provid...
