Embodiment Construction
[0028] Preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art.
[0029] This embodiment provides a method for processing a cell phone case, comprising the following steps:
[0030] Step 1: Lower the blank;
[0031] Step 2: cold extruding the blank through a mold and forming it into a shell blank;
[0032] Step 3: Perform NC rough milling on the shell blank;
[0033] Step 4: Nano-injection after NC rough milling;
[0034] Step 5: Perform NC fine milling after nano injection molding.
[0035] In a more preferred embodiment, in step 2, there are waste edges around the shell blank formed by cold extrusion, therefore, after cold extrusion, the shell blank is rotary cut to remove the waste edges around it, and then Go to step three.
[0036] In a more preferred embodiment, post-processing is carried out after step five i...

The invention discloses a processing method and mold for casings of mobile phones. The processing method for the casings of the mobile phones comprises the following steps of feeding blanks; performing cold extrusion on the blanks through the mold, then performing forming so as to obtain blanks for the casings; performing NC rough milling on the blanks for the casings; performing nanometer injection molding after the NC rough milling; and then performing NC finish milling after the nanometer injection molding. The mold for the processing method for the casings of the mobile phones comprises a forming lower mold with a mold cavity allowing blanks to be placed, a lower limiting part connected with the forming lower mold, a forming punch which can be inserted into the mold cavity and extrudes the blanks, and an upper limiting part which is connected with the forming punch and can be movably matched with the lower limiting part. According to the processing method and mold for the casings of the mobile phones disclosed by the invention, cold extrusion is performed on the blanks, and the NC rough milling is performed, so that the utilization rate of raw materials is high, the waste of the materials is greatly reduced, the processing time is shortened, the efficiency is improved, the equipment investment is small, the yield rate is greatly increased, and the processing quality is stable.
Description
technical field [0001] The invention relates to a mobile phone shell processing method and a mold. Background technique [0002] The traditional mobile phone casing processing technology includes the following steps: rough blank; NC rough milling; nano injection molding; NC fine milling; post-processing. The blank is a flat rectangular parallelepiped. After blanking, the blank is rough-milled directly, and most of it is milled off to form the basic shape of the mobile phone case. This processing method has the following disadvantages: 1. The utilization rate of raw materials is very low, only 35%, resulting in a great waste of material cost; 2. The NC processing time is long, each product takes 65 minutes, and the production efficiency is very low; 3. The equipment investment is large; 4. The production yield is low, only 60%. Contents of the invention [0003] In order to solve the above problems, the purpose of the present invention is to provide a mobile phone shell p...
