In order to achieve the purpose, the invention adopts the main technical scheme that:

the utility model provides a conveniently adjust injection mold of cable sheath diameter, includes from the top down internal mold spare, middle module and external mold spare of threaded connection in proper order, internal mold spare, middle module and external mold spare are the toper structure, internal mold spare top position is provided with the threaded connection seat, internal mold spare bottom position is provided with the threading pipe, form first injection mold chamber between internal mold spare and the middle module spare, form the second mold chamber of moulding plastics between middle module spare and the external mold spare, middle module spare upper portion position is provided with the first coupling of moulding plastics that the first mold chamber of moulding plastics is linked together, external mold spare upper portion position is provided with the second coupling of moulding plastics that is linked together with the second mold chamber of moulding plastics. The thread connecting seat is fixed on the wire platform, and the sinle silk passes the threading pipe, moulds plastics through first coupling of moulding plastics, when needs increase the cable sheath of great size, selects the outer module of suitable size, then through the second coupling of moulding plastics can, more nimble change the diameter of moulding plastics of cable sheath.

Preferably, the bottom clearance between the inner die piece and the middle die piece is 1.2-1.8 times that between the middle die piece and the outer die piece. The synchronous cooling of the injection layer between the inner die part and the middle die part and the injection layer between the middle die part and the outer die part can be ensured, and the integrity of the injection layer is ensured.

Preferably, the bottom clearance between the inner mold part and the middle mold part is 1.63 times that between the middle mold part and the outer mold part.

Preferably, the inner mold part, the middle mold part and the outer mold part are all arranged coaxially.

(III) advantageous effects

The invention provides an injection mold convenient for adjusting the diameter of a cable sheath. The method has the following beneficial effects:

(1) the utility model discloses a cable sheath, including the wire platform, the threaded connection seat, the sinle silk passes the threading pipe, mould plastics through first coupling of moulding plastics, when needs increase the cable sheath of great size, select the outer module of suitable size, then mould plastics through the second coupling of moulding plastics can, the diameter of moulding plastics of cable sheath that has changed more nimble, it is that the diameter that changes the cable simultaneously and need mould plastics need not be centered, has saved a large amount of time.
