Description

Technical Field

[0001] This utility model relates to the field of connector injection molding technology, and in particular to an injection molding structure for a radar connector housing. Background Technology

[0002] The connector housing is usually formed by plastic injection molding. Plastic injection molding requires the use of injection molds, which include an upper mold base and a lower mold base. The inner side of the upper mold base is provided with a concave mold, and the inner side of the lower mold base is provided with a convex mold. The concave mold and the convex mold are arranged opposite each other to form a molding cavity for injection molding. Currently, before injection molding, workers usually insert the terminals onto the convex mold and then perform the mold closing and injection molding operation. There are two problems with manual terminal assembly: (1) Existing connectors have many internal terminals, and it is inefficient to manually insert multiple terminals one by one onto the convex mold; (2) Manually inserting the terminals onto the convex mold is laborious and can easily cause fatigue over time, which can lead to problems such as misassembly and incorrect assembly, affecting the product yield.

[0003] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a radar connector housing injection molding structure to solve the above problems. Utility Model Content

[0006] A preferred technical solution is that the upper mold base or the lower mold base is provided with an injection channel that connects to the injection molding cavity.

[0007] The preferred technical solution is that the top of the movable insert is provided with multiple slots and grooves for fixing the assembly terminals.

[0008] The preferred technical solution is that the fixed mold is provided with a groove for the movable insert to be inserted and fixed.

[0009] The preferred technical solution is as follows: the movable insert is composed of a first insert and a second insert with a plate-like structure; the terminal is configured as an L-shaped structure and includes a vertical section and a horizontal section; the slot is provided on the top of the first insert and is used to position the horizontal section; the slot is composed of a first slot formed on the top of the first insert and a second slot formed on the top of the second insert; and the slot is used to position the vertical section.

[0010] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:

[0011] This utility model proposes an injection molding structure for a radar connector housing. The punch consists of a fixed mold and a movable insert. The movable insert is used to fix the terminal and can be detachably inserted into the fixed mold. That is, the terminal can be pre-installed on the movable insert, and then the movable insert is inserted into the fixed mold. After production verification, this structure greatly improves production efficiency and product yield, and is a mold structure worth promoting. Attached Figure Description
