CN201751212U - Stamping die for characters on mobile phone shell - Google Patents

Abstract

The utility model relates to a stamping die for characters on a mobile phone shell, belonging to the technical field of improving the typing die structure. The characters on the typing die are processed by adopting discharge manner, the edge part of each character is provided with a press rib being 0.1mm in depth. In the improvement, the original wire-cutting cost is reduced, the structure is simplified, the processes are reduced, and the die cost is lowered; and the press ribs can enable the edge and sharp-angled parts of the product to be higher that other parts, thus ensuring that the product can be completely cut when being drilled and cut in later process, greatly reducing reject ratio, and improving the technical operation accuracy.

Description

The diel of phone housing character

Technical field

Advantages such as the utility model relates to a kind of diel, particularly relates to the diel of a kind of punching press character of phone housing, and it has simple in structure, work simplification, reduce cost the applying on making that suit.

Background technology

In the past typewriting mould structure adopts line to cut punching pin, processed complex, and Chen Bengao, and there is the angle of collapsing at the font edge, and is not easy to switch to fully after the back technology drilling, is easy to cause bad result.The processing of this form exists that efficient is low, complicated operation, needs are repeatedly located and shortcoming such as cost height.

The utility model content

In order to overcome the above-mentioned shortcoming of past technology, the utility model provides a kind of and improved production efficiency, simple to operate and phone housing character diel that production cost is low.

The technical scheme that its technical problem that solves the utility model adopts is: typewriting mould character adopts the processing of discharge processing mode; Do the dark beading of 0.1mm at the character edge position.

The beneficial effects of the utility model are: line cuts expense, old reduction of mould before reducing greatly; There is beading can make product character edge and wedge angle position, guarantees when the technology drilling of back, can switch to fully, reduce fraction defective greatly than other position height.Thereby saved machining period greatly, improved production efficiency, reduced production cost, and the processing accurate positioning, easy and simple to handle, the energy uniform pressure reduces edge stress, prolongs die life.

Description of drawings:

Fig. 1 be punching production in machine shell illustraton of model.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

The diel of phone housing character is that this product is produced needs four procedures, that is: blanking, pull and stretch, deburring, punching with process for stamping.Consider special circumstances, only need manufacture and design three cover diel, that is: blanking die, cupping tool and punching dies.Phone housing is the part that cooperatively interacts, has strict assembly relation with other multiple little parts, and the interchangeability when considering actual use still will be strict with the cavity dimension precision of mould when carrying out the mould design.Referring to Fig. 1, the key point of this product is to utilize typewriting mould character to adopt the processing of discharge processing mode, does the dark beading of 0.1mm (1) at the character edge position, and beading can make product character edge and wedge angle position than other position height.

Claims (2)

1. phone housing character diel comprises die matrix, it is characterized in that: there is the dark beading of 0.1mm at the character edge position on die matrix.

2. phone housing character as claimed in claim 1 diel is characterized in that: beading makes product edge and wedge angle position than other position height.
