Specifically, as shown in fig. 10, 16 and 17, the positioning block 8 is movably embedded in the male die 2, and the positioning block 8 is provided with a sliding groove 81; the female die 1 is provided with the shifting rod 11, when the injection die 20 is closed, a part of the shifting rod 11 can extend into the sliding groove 81 and abut against the side wall of the sliding groove 81, and the shifting rod 11 can drive the positioning block 8 to move so as to control the size of the clamping space.

In this embodiment, when the mold is opened, the size of the clamping space surrounded by the positioning block 8 and the accommodating groove 21 is large, so that the second frame body 102 is smoothly placed into the accommodating groove 21, and in the mold closing process, the positioning block 8 can move under the driving of the shift lever 11, so that the size of the clamping space is reduced, and the second frame body 102 is clamped between the positioning block 8 and the accommodating groove 21. The positioning block 8 is movably embedded in the male die 2, so that the risk that the placing difficulty of the second frame body 102 is large due to the fact that the clamping space is small is reduced, the placing difficulty of the second frame body 102 in the accommodating groove 21 is reduced, and the use experience of an operator is improved. The deflector rod 11 is connected with the positioning block 8 through the sliding chute 81, so that the structure of the deflector rod 11 and the positioning block 8 is simplified, and the processing cost of the deflector rod 11 and the positioning block 8 is reduced.

In summary, the injection molding process is as follows: placing a first frame body 101, a second frame body 102 and a third frame body 103 into an accommodating groove 21 of the male die 2, measuring the widths of a first gap 10a, a second gap 10b and a third gap 10c through a measuring tool, comparing the measured widths with a target width, and adjusting the widths of the first gap 10a, the second gap 10b and the third gap 10c through a first positioning piece 6, a second positioning piece 7, a first adjusting component 3, a second adjusting component 4 and a third adjusting component 5 to enable the widths of the first gap 10a, the second gap 10b and the third gap 10c to be matched with the target width; controlling the injection mold 20 to perform mold closing, wherein the positioning block 8 moves under the action of the shift lever 11, so that the second frame body 102 is clamped and fixed in the accommodating groove 21; the injection mold 20 fills plastic into the accommodating groove 21, the first gap 10a, the second gap 10b and the third gap 10c, and after the plastic is cooled and molded, the first frame 101, the second frame 102 and the third frame 103 are fixedly connected; taking out the molded middle frame 10, measuring the width dimensions of the first gap 10a, the second gap 10b and the third gap 10c again to detect whether the dimension of the middle frame 10 meets the requirement, and adjusting the installation positions of the first positioning part 6, the second positioning part 7, the first adjusting component 3, the second adjusting component 4 and the third adjusting component 5 again according to the measurement result to improve the molding precision and the qualification rate of the middle frame 10.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
