Detailed Description

As shown in fig. 1, the utility model discloses an injection mold of socket mold insert insulator, the same with conventional injection molding part mold processing, all include that master model 1 and activity lock joint are at male mould 2 of master model 1 below. The lower edge of the female die 1 is provided with a first forming groove corresponding to the upper shape of the socket insert insulator 9, the lower edge of the male die 2 is provided with a second forming groove corresponding to the lower shape of the socket insert insulator 9, the first forming groove and the second forming groove surround to form a forming cavity for injection molding of the socket insert insulator 9, a forming material is injected into the forming cavity through the glue injection channel and cooled to form a product blank, and a final product is formed after further machining and correction.

In order to realize the injection molding of running through inclined hole 901 on socket mold insert insulator 9 and not later stage machine tooling, the utility model discloses still be equipped with movable core in first shaping groove. As shown in fig. 2, the moving core includes a connecting portion 7 and a molding portion 5. The connecting portion 7 is L-shaped and has a vertical section and a horizontal section. The vertical section is movably inserted in the sliding hole 3 arranged on the female die 1, and the sliding fit between the vertical section and the sliding hole 3 can enable the whole connecting part 7 to be separated from the sliding hole 3 along the vertical direction under the action of gravity or other external force. The horizontal section is provided with a through hole, and the slope of the through hole is the same as that of the through inclined hole 901 to be formed at the corresponding side position. The upper end of the forming part 5 is installed in the through hole in a matching mode, the lower end of the forming part corresponds to the shape of the through inclined hole 901 to be formed and extends into the second forming groove, and the lower end of the forming part 5 is further sleeved with a nut 6 which is embedded into the through inclined hole 901 in the socket insert insulator 9 in a pre-embedding mode. Through frictional resistance cooperation between nut 6 and shaping portion 5, avoid nut 6 directly to fall out or shaping portion 5 is difficult to pull out from nut 6 by the lower extreme of shaping portion 5.
