The upper die 2 is provided with a plurality of positioning pieces 16, the lower die 1 is provided with a plurality of positioning holes 17, and the positioning pieces 16 are embedded into the positioning holes 17. The positioning holes 17 and the positioning pieces 16 are arranged, so that the upper die 2 and the lower die 1 are connected and matched conveniently, the upper die 2 and the lower die 1 are contacted more compactly and are not loosened, the stability of product forming is improved, and the reject ratio of products is reduced.
A plurality of water cooling holes are formed in the upper die 2 and the lower die 1, and each water cooling hole is located in the front surface and the rear surface of the upper die 2 and the lower die 1. A plurality of wire grooves 18 are formed in the upper die 2 and the lower die 1, and each wire groove 18 is connected with the second cavity 13. The upper die 2 and the lower die 1 are both provided with a placing cavity 19, and the placing cavity 19 is connected with the wire groove 18. The wire groove 18 is arranged to facilitate connection and fixation between the wire and the USB outer die in the product forming process, and the placing cavity 19 is used for placing the wire, so that the wire cannot be damaged when the die is closed. A bulge is arranged between the two placing cavities 19 and used for supporting the upper die 2 and the lower die 1.
The mould strip 3 is provided with a runner 14, and the runner 14 is connected with the lower injection groove 6 and the upper injection groove 10. The molding materials enter the mold through the material injection port, flow along the initial section of the material injection groove, the material injection groove and the flow passage 14 and reach the mold cavity to complete the molding of the product. The lower sprue channel 6 cooperates with the upper sprue channel 10 and the runner 14 for completing the molding material from the sprue to the mold cavity.
The mould strip 3 is also provided with a plurality of positioning lugs 15, and the positioning lugs 15 are strip-shaped protrusions, and the size of the positioning lugs is consistent with that of the USB wiring port grooves. The number of the positioning lugs 15 is the same as that of the upper mold cavity 9 and the lower mold cavity 5, and the positions correspond to one another. Each positioning lug 15 is placed in upper die cavity 9 and lower die cavity 5, and die strip 3 is placed in lower die strip channel 4 and upper die strip channel 8.
The working principle and the process are as follows: fixing the mould strip 3 in the lower mould strip groove 4 of the lower mould 1, moving the upper mould 2 to complete the mould closing of the upper mould 2 and the lower mould 1, ensuring the mutual matching among the mould strip 3, the upper mould 2 and the lower mould 1, injecting the material for product forming into the mould through the injection port, and enabling the sizing material in the mould to flow into the mould cavity through the initial section of the injection groove, the injection groove and the runner 14, thereby completing the product forming.
