Embodiment 1

[0051] 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;

[0052] 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;

[0053] 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

[0059] Example 2: Reference Figure 5 , the difference from Example 1 is: the die hole group 1.1 of the end, the die hole group 2.1 of the plug body and the die hole group 3.1 of the sealing part 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. The position of the middle plate positioning member 3.3 is adjusted accordingly.

Embodiment 3

[0060] Example 3: Reference Image 6 , the difference from Example 1 is: 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 the 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 plate exhaust channel 1.9.

Abstract

The invention discloses a high-precision automobile wire harness and a connector waterproof plug die, which belongs to the technical filed of manufacture of the automobile wire harness, and dustproof, splash-proof, anti-drip, waterproof or fireproof parts of a connector. The high-precision automobile wire harness comprises an upper plate, a lower plate and a middle plate, an end die hole set is arranged at the middle part of the upper plate, a plug die hole set and a sealing part die hole set having corresponding position of the end die hole set and the hole amount are respectively arranged on the middle plate and the lower plate; a first lower plate fixing part is arranged around the end die hole set, an upper fixing part corresponding to the position of the first lower plate fixing part is arranged around the sealing part die hole set, and a limitation structure which is used for limiting the closing distance of the upper plate and the lower plate is formed between the first lower plate fixing part and the upper fixing part. According to the invention, machining precision is high, the die is easily positioned, the product repeatability is good, defective goods rate is completely eradicate, and the high-precision automobile wire harness and the connector waterproof plug products can be rapidly produced in a better mode.

Description

technical field [0001] The invention relates to the technical field of manufacturing dust-proof, splash-proof, drip-proof, waterproof or fire-proof parts of automobile wiring harnesses and connectors, and specifically refers to a high-precision 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...
