Detailed Description
As shown in fig. 1, fig. 1 is a schematic structural view of a novel notebook computer plastic part injection mold with screws provided by the present invention.
Referring to fig. 1, the utility model provides a novel notebook computer plastic part injection mold with screws, which comprises an upper mold 1 and a lower mold 2;
a die groove is formed in the lower die 2, a first positioning column 3 is arranged at the bottom of the upper die 1, the upper die 1 and the lower die 2 are matched to form a die cavity, and one end, far away from the upper die 1, of the first positioning column 3 extends into the die groove; between the outer wall of the first positioning column 3 and the inner wall of the mold cavity, a screw receiving chamber arranged around the first positioning column 3 and an injection molding chamber arranged around the screw receiving chamber are formed.
The novel notebook plastic part injection mold's that has the screw concrete in-process of moulding plastics places the screw in lower mould die cavity in advance, then the compound die for the first reference column of going up the mould stretches into the screw internal hole and fixes a position it, then moulds plastics the room of moulding plastics of screw periphery, moulds plastics the back die sinking after the end of moulding plastics, forms the embedded plastic part cylinder structure of screw.
In the embodiment, the novel injection mold for the notebook computer plastic part with the screw is provided with a mold groove on a lower mold, a first positioning column is arranged at the bottom of the upper mold, the upper mold and the lower mold are matched to form a mold cavity, and one end, far away from the upper mold, of the first positioning column extends into the mold groove; a screw accommodating chamber arranged around the first positioning column and an injection molding chamber arranged around the screw accommodating chamber are formed between the outer wall of the first positioning column and the inner wall of the mold cavity. Through the novel notebook plastic part injection mold who has the screw of above-mentioned optimal design, with the screw pre-buried in the erection column in the plastic shell injection moulding process, not only can effectively prevent BOSS post fracture phenomenon, can also reduce cost and improve production efficiency, improve the machining precision greatly.
