Description

10KV vulcanization mold sandwich end socket

Technical Field

The utility model relates to the technical field of mould end heads during vulcanization of lightning arresters, in particular to a 10KV vulcanization mould sandwich end head.

Background

When the composite outer sleeve lightning arrester is vulcanized, screws at two ends of a lightning arrester core body are screwed down, then a half of silica gel is put into a lower die cavity of a vulcanization die, the lightning arrester core body is put into the die, the other half of silica gel is put on the core body, then die assembly operation is carried out, the core body screws are gradually fixed in threaded holes at the end heads along with the pressing of an upper die and a lower die, and the lightning arrester is positioned by the screws at two ends. The screws at the two ends of the lightning arrester in the process have two functions: (1) positioning the lightning arrester to prevent the lightning arrester from moving left and right and from moving back and forth, so that the core body cannot be coated with the rubber, or the rubber coating is not uniform, and the product percent of pass is influenced; (2) the glue is sealed, so that the silica gel is prevented from flowing out along the hole, the lightning arrester is caused to lack of glue, or the silica gel is wasted, the silica gel is stuck on the screw rod, and the treatment is time-consuming and labor-consuming; (3) the screw rod will be damaged by pressure, resulting in the later stage of threading by using the screw die. This requires that the holes of the lightning arrester terminals are closely matched with the diameters of the screws, and the screws are connected with the core body with all deviations in verticality and centrality due to the technical problems of the screws, which causes high frequency of damage to the holes of the lightning arrester terminals.

At present, the easy adhesion silica gel of screw rod at prior art's vulcanization mould presss from both sides core end, both ends when vulcanizing leads to silica gel extravagant to need carry out the silica gel clearance specially to the screw rod, cause manpower resources's waste, and the beneath condition of production effect, and current vulcanization grinding apparatus cooling effect is relatively poor, causes to need longer production manufacturing time, so current vulcanization mould presss from both sides core end and has the easy adhesion of silica gel waste and the relatively poor shortcoming of mould cooling effect.
