Abstract

The invention provides a trimming die structure for a mobile phone casing. The structure comprises an upper die part and a lower die part, and is characterized in that: the upper die part comprises an upper splint, a slanted wedge and a stripper plate; and the lower die part comprises a product positioning die core, a male die cutter, a male die return spring, a male die return stop screw, a male die cutter slide block, a female die cutter, a female die cutter slide block, a female die cutter slide block return spring and a lower die holder. By the trimming die structure for the mobile phone casing, the mobile phone casing is punched from inside to outside by a punching head, so that burrs are generated on the outer surface of the mobile phone casing, assembly of electronic parts of a mobile phone is not influenced, and the use effect of the mobile phone is ensured.

Description

A kind of hand set machine shell shaving die structure

Technical field

The present invention relates to the mould in the machining, specifically is exactly a kind of hand set machine shell shaving die structure.

Background technology

Mobile phone is the electronic product commonly used in people's daily life, and phone housing generally all is to make with stainless steel and other metal materials, and the normal at present mode that adopts of the shaping of metal material is to utilize diel that metal material is formed according to Sheet Metal Forming Technology; The phone housing product is because required precision than higher, in the whole assembling process of mobile phone, all is contained in the inside of phone housing owing to each parts; Assembly precision between each parts requires very high, and the electronic product that especially is contained in the phone housing is very responsive, so the burr that phone housing is produced in punching course need be removed through subsequent handling; Because general enterprise all is to utilize the die-cut from outside to inside phone housing semi-finished product of drift when making phone housing, such processing method makes burr be created in the fitting surface of phone housing, and responsive mobile phone sensitivity is greatly affected; And carry out sharp this employing single die tool carries out the burr removal to metal product the process of removing through subsequent handling; Too, need to utilize many cover metal stamping moulds, increased manpower and materials in complicacy; And because need repeatedly location; Stability is not high, has increased production cost, has reduced production efficiency; Also can increase the percent defective of product, increase production cost control difficulty.

Summary of the invention

Technical problem to be solved by this invention is a kind of hand set machine shell shaving die structure of design; It utilizes cutting head that phone housing is from inside to outside carried out punching press; Impel burr to be created in the outer surface of phone housing, do not influence the assembling of mobile phone electronic part, guaranteed the result of use of mobile phone.

In order to address the above problem, the present invention adopts following technical scheme: a kind of hand set machine shell shaving die structure, and it comprises part of the upper die and part of the lower die; The part of the upper die comprises train wheel bridge, oblique contract, stripper plate; The part of the lower die comprises product orientation core rod, punch cutting knife, punch back-moving spring, punch reset set screw, punch cutting knife slide block, die cutting knife, die cutting knife slide block, die cutting knife slide block back-moving spring, die shoe, and tiltedly contract is contained on the train wheel bridge, and stripper plate is contained on the train wheel bridge through the discharging screw; The product orientation core rod is fixed on the die shoe; Punch cutting knife slide block is contained in the die shoe upper surface, and die cutting knife slide block is contained in the punch cutting knife slide block, and the punch cutting knife is contained in die cutting knife slide block and the product orientation core rod centre position on the punch cutting knife slide block; The die cutting knife is contained on the die cutting knife slide block; Punch back-moving spring and the punch set screw that resets is contained in the die shoe, and tiltedly the contract head is 45 degree inclined-planes, and punch cutting knife slide block and die cutting knife slide block are 135 degree angles with oblique contract corresponding surface.

Said die cutting knife slide block back-moving spring is in compressive state.

Beneficial effect

Need be placed on the product orientation core rod by formed product; The descending stripper plate of mould is pushed down product, and tiltedly contract promotion negative mold cutting knife slide block makes the die cutting knife push down the product shaping place, and tiltedly contract continues descending; Promote punch cutting knife slide block and drive the punch stamping products of outwards advancing; Die-cut from inside to outside, guarantee that burr does not influence the assembling of mobile phone electronic part in product external surfaces, has guaranteed the result of use of mobile phone.
