Example Embodiment
[0036] Example 1: Reference Figure 1~Figure 4 , A waterproof plug mold for automobile wiring harness and connector, comprising an upper plate 1 and a lower plate 2 hinged to each other, and a middle plate detachably arranged between the upper plate 1 and the off-duty 2;
[0037] The middle part of the upper plate 1 is provided with an end 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 to be adapted. Hole group 3.1, used to mold various parts of automobile wiring harness and connector waterproof plug;
[0038] Wherein, the upper board 1 is also provided with a first lower board positioning member 1.2, which cooperates with the upper board positioning member 3.2 on the lower board 3. The first lower board positioning member 1.2 and the upper board positioning Item 3.2 forms a mutual limit function in the form of a cone column and a cone hol...
Example Embodiment
[0044] Example 2: Reference Figure 5 , And the difference from embodiment 1 is: the end mold hole group 1.1, the plug mold hole group 2.1 and the sealing part mold hole group 3.1 are divided into two sections; the middle plate located on the lower plate 3 The positioning member 3.3 is not symmetrically arranged about 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 member adapting hole 1.3 on the upper plate 1 is relative to The position of the middle plate positioning member 3.3 is adjusted accordingly.
Example Embodiment
[0045] Example 3: Reference Image 6 , The difference from embodiment 1 is: the end mold hole group 1.1, the plug mold hole group 2.1 and the sealing part mold hole group 3.1 are divided into three sections; the upper plate 1 is not provided with a first The middle plate stopper 1.5 is provided with an upper plate exhaust passage 1.7 communicating with the end die hole group 1.1 of the upper plate 1, and the lower plate is provided with a position connected to the upper plate exhaust passage 1.7 The corresponding lower plate exhaust channel 1.9.
