Problems solved by technology

Compared with other molding technologies, injection molding technology has its unique advantages. However, the disadvantages of this type of process are also obvious: the equipment required for injection molding is expensive, and the mold structure is relatively complicated. Due to the high cost of injection molding machines and injection molds, the cost of molding equipment The initial investment is relatively large; especially the manufacture of injection molds requires not only high technical level of workers, many auxiliary fixtures and tools, but also long processing cycle

Abstract

The invention discloses a forming process and a special processing device for an ultrathin protective cover sleeve. The forming process comprises the following steps: 1, preparing a cover sleeve material and a die; 2, preparing a vacuum adsorption jig and installing the vacuum adsorption jig in an adsorption device on a working table; 3, starting the vacuum adsorption device and an engraving and milling electric spindle on the working table to prepare a semifinished sheet metal of the ultrathin protective cover sleeve; 4, carrying out surface processing process on the semifinished sheet metal of the ultrathin protective cover sleeve; and 5, using the die for carrying out pressing forming on the semifinished sheet metal of the ultrathin protective cover sleeve by a hot press so as to obtain the ultrathin protective cover sleeve. The working table of the special processing device is provided with the vacuum adsorption device and the engraving and milling electric spindle. The process disclosed by the invention enables forming efficiency of the ultrathin protective cover sleeve to be high and can be used for single plastic or various composite materials to carry out forming processing of the ultrathin protective cover sleeve; the die and equipment are not required to replace; and the special processing device has high processing accuracy and yield, adopts the simple and convenient process, and is beneficial for implementing high-efficiency automatic production and also for saving labor cost.

Description

technical field [0001] The invention relates to the technical field of shell fittings and related production equipment, in particular to a molding process and a special processing device for an ultra-thin protective shell. Background technique [0002] In the production process of plastic molding, injection molding is widely used in the field of plastic processing, especially the production of protective casings for electronic products generally uses plastic injection molding. Compared with other molding technologies, injection molding technology has its unique advantages. However, the disadvantages of this type of process are also obvious: the equipment required for injection molding is expensive, and the mold structure is relatively complicated. Due to the high cost of injection molding machines and injection molds, the cost of molding equipment The initial investment is relatively large; especially the manufacture of injection molds requires not only high-level workers, m...
