Die for vulcanization of watertight connector

Abstract

The invention discloses a die for vulcanization of a watertight connector. The die comprises an upper die, a lower die, locating pins, a flow guide plate, a die release plate, ejector rods and a die opening rod. A whole set of vulcanization device is made of light metal materials. The upper die and the lower die are assembled for accurately positioning the watertight connector, an inner vulcanization cavity is formed, and it is ensured that the vulcanization thickness of the outer surface of the watertight connector is kept consistent. The flow guide plate is designed to be of a movable structure and is formed by combining two plates, a V-shaped flow guide groove can be formed by the flow guide plate, the flow guide plate is also demounted conveniently, and feeder removal is achieved. The locating pins are asymmetrically distributed, and cooperation accuracy can be improved. The die opening rod and the die release plate are combined to form a die release mechanism, so that the upper die and the lower die can be conveniently disengaged perpendicularly, and a vulcanization surface cannot be torn. The vulcanization device has the beneficial effects of being high in casting speed, even in vulcanization layer thickness, good in vulcanization surface quality, capable of facilitating die release and being used repeatedly, easy to operate and the like.

Description

technical field [0001] The invention relates to a mold for watertight connector vulcanization. technical background [0002] At present, the vulcanization device used for underwater optical cables or sonar system watertight connectors usually uses two materials, one is PVC material, this kind of mold is disposable, the cost is high, and it is not suitable for use in occasions that require batch vulcanization; The second is to use light metal materials, which can be reused. Generally, a two-layer structure is adopted, namely the upper mold and the lower mold. After the mold is fixed, the mold must be rotated 90° so that the glue filling port is facing upwards to vulcanize. After vulcanization, the mold needs to be restored to the original position for demoulding. This operation process is more troublesome, and it cannot be used for some special occasions. When the watertight connector is rotated, it cannot be vulcanized. At the same time, due to the existence of the glue fil...

[0002] At present, the vulcanization device used for underwater optical cables or sonar system watertight connectors usually uses two materials, one is PVC material, this kind of mold is disposable, the cost is high, and it is not suitable for use in occasions that require batch vulcanization; The second is to use light metal materials, which can be reused. Generally, a two-layer structure is adopted, namely the upper mold and the lower mold. After the mold is fixed, the mold must be rotated 90° so that the glue filling port is facing upwards to vulcanize. After vulcanization, the mold needs to be restored to the original position for demoulding. This operation process is more troublesome, and it cannot be used for some special occasions. When the watertight connector is rotated, it cannot be vulcanized. At the same time, due to the existence of the glue filling hole during the demoulding process, the demoulding force near the glue filling hole will increase, resulting in uneven demoulding and tearing on the surface of the vulcanized layer. crack
