Description

Technical Field:

[0001] The utility model relates to the technical field of mold products, and particularly refers to a 90-degree bent-angle plug forming mold. Background Art:

[0002] The connector of general electronic products and the plug pin of electrical appliances are called plugs.

[0003] Combined with Figure 1-2 As shown, for the 90-degree bent-angle plug 4 on the market, the 90-degree bent-angle plug 4 generally includes a plug body 41, a PCB board 42 welded and fixed to the end of the plug body 41 and perpendicular to the plug direction of the plug body 41, a wire 43 welded to the PCB board 42, and an outer mold 44 integrally injection-molded at the ends of the plug body 41 and the wire 43. The outer mold 44 wraps the ends of the plug body 41, the PCB board 42, and the wire 43, connecting the ends of the plug body 41 and the wire 43 into one body, and the plug body 41 and the wire 43 are perpendicular to each other, distributed at 90 degrees.

[0004] Among them, the injection molding of the outer mold 44 is generally set as the last step. Combined with Figure 3 As shown, for the forming mold 5 of the outer mold 44, the forming mold 5 includes a bottom mold 51 and an upper mold (not shown in Figure 2) arranged on the bottom mold 51. The bottom mold 51 is provided with two symmetrically distributed first cavities 511, a first positioning groove 512 and a second positioning groove 513 communicated with both ends of the first cavity 511. The bottom surface of the upper mold is provided with a second cavity, a third positioning groove and a fourth positioning groove corresponding to and adapted to the first cavity 511, the first positioning groove 512 and the second positioning groove 513 respectively. The first positioning groove 512 is docked with the third positioning groove to position the plug body 41, the second positioning groove is docked with the fourth positioning groove to position the wire 43, the second cavity is docked with the first cavity 511 to form a cavity for the outer mold 44. The ends of the plug body 41, the wire 43 and the PCB board 42 are all placed in the cavity, and plastic material enters the cavity and is cooled and fixed to form the outer mold 44.

[0005] That is to say, the above-mentioned mold is a two-cavity mold, symmetrically distributed left and right. Its quantity is small, and only two products can be processed and formed at a time, which is not conducive to improving efficiency and production capacity; because the two first cavities 511 are symmetrically distributed on the bottom mold 51, after the plug body 41 welded with the wire is placed in the first cavity 511, the two wires extend out along both sides of the bottom mold, which is not convenient for arranging the wires and makes the wires messy; finally, because the plug body 41 welded with the wire is directly placed in the first cavity 511 one by one, its placement efficiency is not high, and it cannot ensure the consistency of placement, nor can it improve efficiency.
