Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, in particular to a split terminal and an injection molding and encapsulation mold therefor. Background Art

[0002] As Figure 1 shown, the terminal 01 of the housing of the existing new energy vehicle thermal management module includes four metal terminals 011, and the four metal terminals 011 are arranged in two layers in a staggered manner.

[0003] As Figure 2 and 3 shown, when using the existing injection mold to inject and form the terminal of the housing of the new energy vehicle thermal management module as Figure 1 shown, two opposite positioning sliders 02 and support blocks 03 must be provided. An insertion groove (not shown in the figure) is provided at the docking end of the positioning slider 02; the support block 03 is inserted into the insertion groove. Positioning grooves 031 for placing the metal terminals 011 are provided on both the top surface and the bottom surface of the support block 03, and after the support block 03 is inserted into the insertion groove on the positioning slider 02, the positioning grooves 031 cooperate with the side walls of the corresponding insertion grooves to position the metal terminals 011. During injection molding, the operator needs to first insert one end of the metal terminal 011 into the positioning groove 031, and then push the two positioning sliders 02 during mold closing so that the other end of the metal terminal 011 is inserted and fixed in the positioning groove 031 at the corresponding end, that is, the two oppositely arranged positioning sliders 02 and the support block 03 are used in cooperation to position the metal terminals 011. However, when using such an injection mold to inject and form the terminal of the housing of the new energy vehicle thermal management module as Figure 1 shown, the following problems exist:

[0004] 1. The injection mold has a complex structure and a high manufacturing cost;

[0005] 2. The first end of the metal terminal 011 is clamped by the cooperation of the positioning slider 02 and the support block 03, and the second end of the metal terminal 011 is inserted into the positioning groove 031 formed by the cooperation of another positioning slider 02 and the support block 03 during mold closing. However, since the metal terminal 011 is a special-shaped terminal similar to a Z shape, the two oppositely arranged positioning sliders 02 in the injection mold are located in different horizontal planes, resulting in the second end of the metal terminal 011 being unable to accurately insert into the corresponding positioning groove 031, and thus the qualified rate of the injected terminal 01 is low and it is not suitable for mass production;

[0006] 3. Since the metal terminal 011 is inserted into the positioning groove 031 formed by the cooperation of the positioning slider 02 and the support block 03, once it is missed, glue will enter the positioning groove 031 during injection molding, resulting in damage to the injection mold.
