Description

Technical Field

[0001] The utility model relates to the technical field of notebook computer processing, in particular to an injection mold for a notebook computer back cover. Background Art

[0002] Laptops, also known as "portable computers, handheld computers, handheld computers or laptops", are characterized by their compact body. They are more portable than desktop computers and are small and easy to carry. In the production process of laptops, injection molds are usually used to assemble the back cover of the computer with the laptop after injection molding.

[0003] With traditional injection molds, after the computer back cover is injection molded, the worker needs to clamp the top of the computer back cover and lift it up to complete demolding. Long-term demolding increases the worker's fatigue and reduces their work efficiency. At the same time, the surface temperature of the computer back cover is too high during injection molding, and the demolding operation can only be performed after the surface temperature of the computer back cover cools down. As a result, the temperature of the computer back cover cannot be cooled quickly, which reduces the processing efficiency of the laptop back cover.

[0004] According to the publication number: CN204622467U, a computer shell injection mold is provided, which is composed of a main mold, a sub-mold, a convex block A, a convex block B, and a convex block C. The main mold is square-shaped, a through hole is provided on one side of the main mold, a thread is provided on the surface of the through hole, a connecting pipe is provided on the through hole, and the connecting pipe is detachably connected to the through hole; a groove A is provided in the middle part of the main mold, a cavity is formed by the groove structure, a convex block A is provided at one vertex of the groove A, the convex block A is rectangular, the height of the convex block A is consistent with the depth of the groove A, and the number of the convex blocks A is three; a convex block B is provided at the other opposite vertex of the groove A, and the convex block B is square-shaped; a convex block C is provided on the other side of the convex block B, and the convex block C is also square-shaped; the sub-mold is square-shaped, and the size of the sub-mold is consistent with that of the main mold; a groove B is provided in the middle part of the sub-mold, a square convex block is provided on the groove B; a convex block A is also provided at one vertex of the groove B. The utility model ensures the heat dissipation performance of the finished computer shell.

[0005] According to the injection mold introduced above, the staff needs to clamp the top of the computer back cover and lift it up to complete demolding. Long-term demolding increases the staff's fatigue and reduces their work efficiency. At the same time, the surface temperature of the computer back cover is too high during injection molding. The demolding operation can only be performed after the surface temperature of the computer back cover is cooled. As a result, the temperature of the computer back cover cannot be cooled quickly, which reduces the processing efficiency of the laptop computer back cover. Therefore, we need to propose an injection mold for the laptop computer back cover. Utility Model Content
