Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] like Figure 1-9 Shown, the present invention comprises upper mold 11, lower mold 19, left mold core 12, right mold core 17, housing 16, jack 15, positioning pin 13 and jacking screw rod 18, wherein left mold core 12, positioning pin 13 , jack 15, housing 16 and right mold core 17 are located between upper mold 11 and lower mold 19.

[0026] The axial sections of the left mold core 12 and the right mold core 17 are both "T" shaped, and the left mold core 12 is provided with holes for installing positioning pins 13 along the axial direction, and the right mold core 17 is provided with holes in the axial direction which are compatible with the left mold core. The first blind hole 24 of the same position as the hole on the core 12, one end of the positioning pin 13 is inserted in the hole, the other end is inserted in the second blind hole 25 provided at...

Abstract

The invention relates to a mold for vulcanization of an underwater connector, in particular to the mold for manufacturing a plug of a watertight connector and a manufacturing method thereof. The mold comprises an upper mold, a lower mold, a tightening threaded rod, a left mold core, a positioning pin, an inserting hole, a shell and a right mold core, wherein the left mold core, the positioning pin, the inserting hole, the shell and the right mold core are positioned between the upper mold and the lower mold. Firstly, roughening, cyclizing and primer coating are carried out on the inserting hole and the shell, after primer is dried, the shell, the inserting hole and the positioning pin are arranged inside the mold cores, the mold cores are placed in a preheated mold cavity, mold clamping is carried out, the mold is placed on a vulcanizing machine, pressurization, glue injection and vulcanization are carried out, after a set time has passed, a workpiece is cured, and the workpiece can be taken out from the mold. The key of the manufacturing method lies in the tightening threaded rod, after the mold clamping of an upper mold and a lower mold is carried out, the tightening threaded rod is screwed tightly, so that the left mold core, the inserting hole and the right mold core are in close contact with each other, a gap does not exist in the end face of the inserting hole and the end face of a positioning small pin of the left mold core, the phenomenon that glue dose not enter the inserting hole during the glue injection process is guaranteed, and the mold and manufacturing method of the mold are suitable for manufacturing of plugs of different types of watertight connectors.

Description

technical field [0001] The invention relates to a mold for vulcanizing an underwater connector, in particular to a mold for making a watertight connector plug and a manufacturing method thereof. Background technique [0002] With the increasing application of underwater robots (ROV), underwater self-propelled vehicles (AUV) and some underwater equipment, the requirements for the reliability of underwater connectors are getting higher and higher. The existing production method has the following problems: when the plug is injected with glue during vulcanization, some glue enters the inside of the socket, which leads to poor contact between the pin and the socket, and affects the electrical performance index. Contents of the invention [0003] In order to solve the phenomenon of glue entering the socket in the existing manufacturing method, the purpose of the present invention is to provide a mold for making a watertight connector plug and a manufacturing method thereof that ...
