Description

Die-cut mould of five metals die-casting cell-phone medium plate

Technical Field

The utility model relates to a technical field of the die-cut mould of cell-phone medium plate especially relates to a be applied to the die-cut mould of cell-phone medium plate after five metals die casting technology handles.

Background

With the development of communication technology, the application range of smart phones is also more and more extensive, thereby greatly increasing the demand of smart phones. The existing smart phone generally comprises a screen, a mainboard, a mobile phone support and a battery, and a middle plate on the mobile phone support is usually made of a metal material. At present, the middle plate of a middle-high-end smart phone is processed mainly in the following three ways: 1. the whole profile is processed by CNC, the appearance is subjected to anodic oxidation treatment, and the method is suitable for high-end machine types. The middle plate obtained by the processing method has the characteristics of high strength and high-grade and attractive appearance, so that most of high-grade machine types adopt the process, but the process has high cost. 2. The middle plate is formed by die casting, and machined appearance inserts are adopted on the periphery after injection molding, so that the cost is moderate, but the overall appearance is poor due to the limitation of an embedding process, and the middle plate injection molding method can only be suitable for middle and low-end machine types. 3. The metal is integrally formed by die casting by adopting a special die casting material, the surface adopts a spraying process, and the metal texture is reflected by highlight treatment at the periphery. Such mode processing cost is low, but firstly the spraying can't accomplish metal feel, secondly high-gloss limit sand hole leads to the yield to reduce for the center of this kind of mode production is not suitable for high-end model, and the management and control difficulty during batch production simultaneously, output promotes the degree of difficulty greatly. The current mainstream mobile phone middle plates are all made of aluminum alloy materials through die casting; the aluminum alloy material flows through the die cavity in a molten state very well, so that the die-cast aluminum alloy middle plate has high yield. Therefore, at present, the three processes are comprehensively and alternately applied, for example, the aluminum alloy mobile phone middle plate is prepared by a die-casting process, and then the CNC process and the die-cutting process are alternately used for optimizing the shape of the mobile phone middle plate. Based on this, chinese patent CN214768230U discloses a cell-phone medium plate stamping die, it includes mould and lower mould, it sets up directly over the lower mould to go up the vertical setting of sliding of mould, the vertical drift that is provided with on the diapire of mould, the vertical blanking hole of offering with drift size adaptation on the lower mould, radially seted up the mounting groove along the blanking hole on the inner wall in blanking hole, it peels off the piece to slide along mounting groove depth direction in the mounting groove to be provided with, be provided with in the lower mould and be used for ordering about to peel off the driving piece that the piece stretches out the mounting groove. Above-mentioned disclosed cell-phone medium plate stamping die has the effect that improves the blanking efficiency of blanking waste material.

However, the blanking efficiency of the mobile phone middle plate stamping die disclosed above can be further improved. Specifically, in the work flow of the mobile phone middle plate stamping die, when the punch of the upper die moves downwards to stamp the mobile phone middle plate on the lower die into the hole, the cut material is pushed downwards into the blanking hole along with the punch. When the upper die rises to drive the punch to rise from the blanking hole, the stripping block is driven to abut against the side wall of the punch, so that when the punch rises to be separated from the blanking hole, the stripping block strips waste materials clamped on the punch. Therefore, the mobile phone middle plate stamping die disclosed above enables waste materials to be stripped by driving the stripping block to abut against the side wall of the punch. The mold with the stripping block arranged independently has a complex structure and high maintenance cost.
