Modularized die-casting method and die-casting apparatus for middle plate of mobile phone

Abstract

The invention discloses a modular die-casting method and die-casting apparatus for a middle plate of a mobile phone and belongs to the technical field of electronic accessories. The die-casting apparatus comprises a die assembly, the top of the die assembly is connected with a brushing assembly, the bottom of the die assembly is sequentially connected with a transferring assembly and a cutting assembly; a brushing servo motor rotates anticlockwise, so that a first rotating rod drives one end of a first rotating plate to anticlockwise rotate by 90 degrees, multiple sets of bristles are located at the tops of two sets of die cavities of a machine shell correspondingly; an electric push rod conducts telescopic movement, lubricating oil in a liquid storage box coats the inner surfaces of the two sets of die cavities through the multiple sets of bristles; and after coating is completed, the brushing servo motor is started to rotate clockwise, so that the first rotating rod drives one end of the first rotating plate to rotate 90 degrees clockwise to return to the original position. Compared with a traditional lubricating oil spraying mode, the die-casting apparatus can reduce the use amount of the lubricating oil, and avoids the situation that product quality is affected due to the fact that the lubricating oil is gathered in the die cavities.

Description

technical field [0001] The invention relates to the technical field of electronic accessories, in particular to a modular die-casting method for a middle board of a mobile phone and die-casting equipment thereof. Background technique [0002] At present, in the die-casting equipment of the mobile phone mid-plate, lubricating oil is usually sprayed on the inner surface of the mold cavity by spraying. Too much lubricating oil is used, and it gathers inside the mold cavity, which affects the quality of the product, and the rough parts of the mobile phone mid-plate After the mold cavity is formed, most of the materials are directly blanked, and it is impossible to cut off the redundant connection of the mobile phone mid-plate blank. Therefore, we propose a modular die-casting method and die-casting equipment for the mobile phone mid-plate. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a modular die-casting method...

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the present invention provides a modular die-casting method and die-casting equipment for mobile phone mid-plates, which solves the problem of spraying lubricating oil on the inner surface of the mold cavity in current die-casting equipment for mobile phone mid-plates. If the amount of lubricating oil used is too much, it will accumulate inside the mold cavity, which will affect the quality of the product. After the blank parts of the middle plate of the mobile phone are formed in the cavity, most of them will be directly blanked, and the redundant connection of the blank parts of the middle plate of the mobile phone will not be possible. The problem of excision
