The second round platform hole, the holes for optical cables that footpath is gradually reduced；First round platform is located in first round platform hole, and the cylinder is located at
In the cylindrical hole, second round platform is located in second round platform hole.
Pass through above-mentioned technical proposal, one section of cylindrical hole is added in the through hole so that extrusion molding intracavitary forms one section and delayed
Region is rushed, the irregular concussion that screw rod is brought is fallen in neutral straight section to buffering, and then increases cable size stability, in addition
The buffer area helps to alleviate die pressure, reduces the generation of salivation, avoids the optical cable bulge of production, has effectively ensured production
The quality of product.
In further technical scheme, cooling chamber is provided with the die sleeve in the outside of the holes for optical cables, on the die sleeve
Provided with the cooling liquid inlet and cooling liquid outlet connected with the cooling chamber；The setting can be played cold to the optical cable of extrusion moulding
But effect, so as to further reduce the generation of salivation.
In further technical scheme, the taper of first round platform is identical with the taper of first round platform hole, described
The taper of second round platform is identical with the taper of second round platform hole, and the taper of first round platform is 0.46-0.62, preferably
0.54, the taper of second round platform is 0.14-0.22, preferably 0.18.
The mould can set the cylinder hole section of multiple different-diameters according to being actually needed in through hole, and then in extrusion molding chamber
Interior formation multiple buffering area, effectively ensure the stability of cable size, reduce the generation of salivation.
(3) beneficial effect
Compared with prior art, the technical solution of the utility model has advantages below：The mould increases in the through hole
One section of cylindrical hole is added so that extrusion molding intracavitary forms one section of buffer area, and the irregular concussion that screw rod is brought is in neutral straight
Section is fallen to buffering, and then increases cable size stability, and the buffer area helps to alleviate die pressure in addition, reduces salivation
Produce, avoid the optical cable bulge of production, effectively ensured the quality of product；Cooling chamber is provided with the outside of holes for optical cables, can be right
The optical cable of extrusion moulding plays a part of cooling, so as to further reduce the generation of salivation.
