Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 1-3, the present embodiment provides an injection mold for encapsulating terminals, including an upper mold 1, a lower mold 2, a clamping assembly 3 for clamping terminals, and an insertion supporting assembly 4 located between the clamping assembly 3 and the lower mold 2.
Go up mould 1 and be located the top of lower mould 2, and go up mould 1 and locate to weld perpendicularly towards the position of lower mould 2 and have the guide post, offer on the lower mould 2 with the post groove of guide post looks adaptation, in this embodiment, at the in-process of last mould 1 and 2 compound dies of lower mould, stretch into the effect in order to play accurate counterpoint compound die in the lower mould 2 through the guide post along the post groove. A cavity is formed between the upper die 1 and the lower die 2, and the terminal is encapsulated and formed in the cavity to obtain an injection product. An injection molding opening is arranged in the lower die 2 in a penetrating way and communicated with the die cavity. In this embodiment, the terminal is installed into the implantation site along the clamping component 3, the terminal is assembled in the cavity of the lower die 2 along with the terminal by the insertion supporting component 4, then the upper die 1 and the lower die 2 are closed, and glue is injected through the injection port to perform injection molding and encapsulation of the terminal.
The clamping assembly 3 is used as a core mold to be carried in a terminal implantation area of the injection mold and plays a role in clamping the terminal. The clamping assembly 3 includes a clamping block 31 provided on the lower die 2, a slot 32 opened on the clamping block 31, and a terminal engaging slot 33. The clamping block 31 is positioned in the cavity, and the bottom surface of the clamping block 31 is contacted with the lower die 2.
