In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a submarine cable salvagees and uses vulcanization section of thick bamboo head mould, its includes interior side form and outside mould, form half side body space and with between the concatenation back of interior side form and outside mould the filling channel and the balanced passageway that half side body space is linked together, half side body space is including being half annular inlayer body space and locating on the inlayer body outer peripheral face and be half annular outer body space, inlayer body space with outer body space is linked together, the distance of outer body space with the both ends in inlayer body space is a, b respectively, the external diameter in outer body space is c, 4:5 is more than or equal to a: 5, 1: c is more than or equal to 1, b is more than or equal to 15: 17.

In another optimized scheme, the circumferential surface and the end surface of the inner-layer pipe body space are in arc transition.

In another optimization scheme, a: b is 1: 2.

In another optimization scheme, c: b is 15: 16.

In another preferred embodiment, the injection channels are respectively located at two ends of the half-side tube body space, and the balance channel is located on the circumferential surface of the half-side tube body space.

In another optimized scheme, the three injection channels at any end part of the half-side pipe body space are uniformly distributed.

In another optimized scheme, the balance channels are communicated with the circumferential surface of the half-side pipe body space, a group of balance channels are respectively arranged on two sides of the outer-layer pipe body space, and the balance channel on the same side is located on the end surface of the inner-layer pipe body space on the side where the balance channel is located and the midpoint between the outer-layer pipe body spaces.

Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages: the distances between the space of the outer layer pipe body and the two end parts of the space of the inner layer pipe body are respectively a and b, the outer diameter of the space of the outer layer pipe body is c, 4:5 is more than or equal to a: b is more than or equal to 1:5, 1: c is more than or equal to 1, b is more than or equal to 15:17, the relative positions of the outer layer pipe body and the inner layer pipe body of the half-side pipe body after forming are adjusted, when one end, far away from the outer layer pipe body, of the end face of the inner layer pipe body is inserted into the vulcanizing cylinder, reinforcing rings are uniformly arranged at two end portions of the inner layer pipe body, uniform stress of the inner layer pipe body is guaranteed, accordingly, the strength of the inner layer pipe body is improved, the problem that chips fall when the inner layer pipe body is extruded is solved, bidirectional injection is achieved, forming is fast, and the efficiency is improved by more.
