Embodiment 1

[0036] Example 1: Reference Figure 1~Figure 4 , an automobile wiring harness and connector waterproof plug mold, including an upper plate 1 and a lower plate 2 hinged to each other, and a detachable middle plate arranged between the upper plate 1 and the lower plate 2;

[0037] The middle part of the upper plate 1 is provided with a terminal mold hole group 1.1, and the middle part of the middle plate 2 and the middle part of the lower plate 3 are respectively provided with a plug body mold hole group 2.1 and a sealing part mold that are intended to be adapted. Hole group 3.1 is used to mold various parts of the automobile wiring harness and connector waterproof plug;

[0038] Wherein, the upper plate 1 is also provided with a first lower plate positioning member 1.2, which cooperates with the upper plate positioning member 3.2 on the lower plate 3, and the first lower plate positioning member 1.2 and the upper plate positioning Part 3.2 forms the function of mutual limitati...

Embodiment 2

[0044] Example 2: Reference Figure 5 , the difference from Example 1 is that: the end die hole group 1.1, the plug body die hole group 2.1 and the sealing part die hole group 3.1 are divided into two sections; the middle plate located on the lower plate 3 The positioning piece 3.3 is not arranged symmetrically with the central axis of the lower plate 3, which facilitates the positioning of the middle plate and prevents reverse installation. At the same time, the position of the middle plate positioning piece adapter hole 1.3 on the upper plate 1 is relatively The position of the middle plate positioning member 3.3 is adjusted accordingly.

Embodiment 3

[0045] Example 3: Reference Figure 6 , the difference from Example 1 is that: the die hole group 1.1 of the end, the die hole group 2.1 of the plug body and the mold hole group 3.1 of the sealing part are divided into three sections; the upper plate 1 is not provided with a first The middle plate limiter 1.5 is provided with an upper plate exhaust channel 1.7 communicating with it around the end die hole group 1.1 of the upper plate 1, and the lower plate is provided with a position that is in line with the upper plate exhaust channel 1.7 Corresponding lower panel exhaust channel 1.9.

Abstract

The invention discloses an upper plate of a waterproof plug mold for an automobile wire harness and a plug connector, and belongs to the technical field of manufacturing of dustproof, splash-proof, drip-proof, waterproof and fireproof parts of the automobile wire harness and the plug connector. A hinged part connected to a lower plate is arranged on one side of the upper plate, an end mold hole set formed by arranging mold holes in an array mode is arranged in the middle of the upper plate, and first lower plate locating parts are arranged around the end mold hole set. According to optimization of the technical scheme, the first lower plate locating parts are conical holes or conical columns. The upper plate can be matched with a middle plate and the lower plate, the mold can be located easily, the product repeatability is good, and the probability of defective goods is basically eliminated.

Description

technical field [0001] The invention relates to the technical field of manufacturing dust-proof, splash-proof, drip-proof, waterproof or fireproof parts of automobile wiring harness and connectors, and specifically refers to an upper plate of a mold for waterproof plugs of automobile wiring harnesses and connectors. Background technique [0002] When the connector on the car is connected by crimping wires, it is necessary to provide a waterproof plug at the connection, so that the wires can be passed through the waterproof plug to connect the connector, so as to realize the waterproof function and prevent damage to the equipment caused by leakage and water ingress. [0003] The waterproof plug usually includes a sealing part composed of a terminal, a plug body and several sealing rings. The Chinese utility model patent with the authorized announcement number CN204992102 U discloses a waterproof plug for an automobile connector, which has a simple structure, good fixing and se...
