Example 2:

The following is a three-phase four-way branch wire injection molding encapsulation process through the mold:

As shown in fig. 2-3, in fig. 2, a three-in and three-out branch wire 5 has two connection points, and a three-in and three-out branch wire structure is formed by two connection points, wherein one in means that one branch line is a current input branch line, and the other three branch lines are current output branch lines.

Three groups of one-in three-out branch wires 5 are selected, and are arranged according to the structure in fig. 3, two ends of the rectangular structure are wiring points, and if glue injection is implemented by adopting a traditional die, the wiring points are easily contacted to form short circuit. Therefore, the junction points of each group of the one-in three-out branch electric wires 5 need to be isolated. Three groups of one-in three-out branch wires 5 are placed to form a three-phase four-way branch wire structure.

The three groups of one-inlet and three-outlet branch wires 5 in fig. 3 are placed in the mold of the utility model to form a placement structure as shown in fig. 4, each branch wire is led out from a corresponding U-shaped line groove as can be seen from fig. 4, the wiring points on the three groups of one-inlet and three-outlet branch wires 5 are separated by 2 mold barriers 3, and the wiring points are ensured not to be contacted in the injection molding encapsulation process through the mold barriers 3.

The mold is fed into an injection molding encapsulation device, and the encapsulation is performed once by the injection molding encapsulation device, so as to form a primary encapsulation structure shown in fig. 5. The three-phase four-way branch wire after one-time encapsulation molding is taken out, and two one-time molding kidney-shaped holes 61, two one-time molding cylindrical holes 62 and two space-apart hole sites 63 are formed on one-time injection molding encapsulation 6. For the appearance of the encapsulation to be attractive and durable, the primary injection molding encapsulation 6 needs to be subjected to secondary encapsulation molding.

In the secondary overmolding, since the conventional mold does not have the mold barrier 3, the void space 63 is filled.

The three-phase four-way branch wire after the secondary molding of fig. 7 is taken out, and the encapsulation structure forms the secondary injection molding encapsulation 8 shown in fig. 8. In fig. 8, the post-formed kidney-shaped hole 81 and the post-formed cylindrical hole 82 are mounting holes.

In summary, the mold of the utility model sets the mold barrier 3 in the groove to form the line passage, and forms the space hole 63 after injection molding, the space hole 63 separates the wiring points, and the short circuit of the wiring points is avoided. The die also designs a mounting hole forming column for forming the mounting hole.
