Abstract

The invention discloses a rubber injection mold of an insulator. The rubber injection mold comprises a mold frame, a runner plate and inserts, wherein the inserts form umbrella pages; the runner plate and the inserts are installed on the mold frame; rubber filling channels are arranged on the runner plate; rubber filling holes are formed in the rubber filling channels; both sides of the rubber filling holes are arranged opposite to each other; the rubber filling holes correspond to fourteen one-level rubber filling channels; the inserts correspond to the rubber filling channels; air discharge slots are formed in the inserts; and double-side rubber filling is adopted. The rubber injection mold is high in rubber filling speed, good in air discharge effect, short in molding time, high in production efficiency, low in power consumption and the like. The injection time is only about 3 minutes, because the injection time is short, injection can be directly carried out at the vulcanization temperature of about 160 DEG C, the injection time and the cooling time can be saved, the energy consumption is about 50KW per injection, and the efficiency can be improved by more than 40%.

Description

technical field [0001] The invention relates to a mold for industrial production, in particular to a rubber injection mold for an insulator. Background technique [0002] In the prior art, the structure of the rubber injection mold for producing high-voltage power transmission and transformation hollow insulators is as follows: figure 1 As shown, it includes a mold frame 1, a runner plate 2 and an insert 3 forming an umbrella page. The runner plate 2 and the insert 3 are installed on the mold frame 1. There is a glue inlet on the runner plate 2, and the glue inlet There are glue inlets 4, and each glue inlet corresponds to a plurality of inserts 3 that form umbrella pages. There are exhaust grooves 31 on the inserts 3, and there are only four or eight glue inlets on the entire mold. The rubber injection mold with this structure can only be injected at about 120°C due to the limitation of the number and position of the injection points, and the injection time is about 30 min...
