Description

Shell diel

Technical field

The utility model is related to mould applications, and in particular to a kind of shell diel.

Background technology

HDMI（High Definition Multimedia InterfaceI）, also known as HDMI is A kind of totally digitilized image and sound transmit interface, can transmit unpressed audio and vision signal.HDMI is designed to The audio-visual transmission interface of the older simulation of substitution is such as terminals such as SCART or RCA.It supports all kinds of TVs and computerized image form, Including SDTV, HDTV video pictures, along with multi-sound channel digital audio.In transmission, various video datas will be received and dispatched by HDMI Chip is with " minimum differential signal transmission "（TMDS）Technology for encoding is into data packet.Its maximum pixel is passed when being worked out at the beginning of specification Defeated rate is 165Mpx/sec, it is sufficient to support 1080p image quality 60 pictures per second, or UXGA resolution ratio（1600x1200）；Later Amplification is 340Mpx/ seconds in the specifications of HDMI 1.3, to meet following possible demand.

To meet HDMI functional requirement, there is higher requirement, especially its sealing to the shell of HDMI connectors Energy.In the Punching Process of existing HDMI shells, not up to certain measure of precision, the requirement to pressing equipment is unusual Although height, preferable shell precision is ensure that using the equipment of import, but equipment price is expensive, and maintenance cost is high, significantly The cost for improving production；Using general pressing equipment, because during processing, the less stable of equipment is limited The sealing degree of cooperation of HDMI connector shells is made.

Utility model content

In view of this, in order to solve technical problem present in prior art, the utility model provide it is a kind of it is simple in construction, Production cost is low, good processing stability, can improve mould carve close precision shell diel.

The technical solution of the utility model is：A kind of shell diel, including drift, punching press base, the drift bag Drift shell is included, the drift is internally provided between mould, upper mould and the drift shell and is provided with elastomer block, the elasticity Block is closely connected with the drift, upper mould；The punching press base includes upper bed-plate and lower bottom base, the upper bed-plate and the bottom Gap is provided between seat and is correspondingly arranged, the upper bed-plate surface is provided with lower mould, the upper mould and the lower mould Corresponding matching.

Further, the first magnet layer is provided with below the upper bed-plate, the lower bottom base is made up of the second magnet layer. Particularly, the area of second magnet layer is 1.5 times of the first magnet aspect product.

Further, the first magnet layer, the second magnet layer inside are equipped with coil, and the coil is connected with electricity Source, the magnetic of the first magnet layer and the second magnet layer is repelled each other.

Further, the upper bed-plate surface is symmetrically arranged with baffle plate positioned at the lower mould both sides, and the drift is inscribed within The accommodation space formed between the baffle plate.

Further, the lower bottom base is fixedly installed on processing table top.

Further, the cross section of the elastomer block is Le Lip river triangle.

Further, the modulus of elasticity of the elastomer block is 0.22-0.31MPa.

Diel is referred to as chill again, and it is to be acted on using stamping machine pressure on mould, makes to put in a mold Solid material produces the change of shape.There are stretching die blanking dies, bender, riveting die etc. from the function point of mould.Blanking die has Simple single punch-die and the baroque progressive die, primary concern is that lathe pressure, Dies ' Blanking power, mould stripping force, punching Cut out the sex chromosome mosaicism rational in infrastructure of gap and complicated shape.Shell diel of the present utility model, using the processing side of blanking die Formula, by the effect for the elastomer block being arranged on inside drift, can for blanking pressure of the raw material during punching and Stripping force reaches optimization balance, by the baffle plate and drift on punching press base, and the fit system of upper mould and lower mould enters inside drift One step defines the gap of punching so that whole shell processing technology is optimized well；By the way that punching press base is set into magnetic Property the magnet layer that repels each other, ensure there are enough active forces between the first magnet layer and the second magnet layer by the way of the electromagnetism, enter The area by the second magnet layer of one step is set to 1.5 times of the first magnet aspect product, ensure that in Punching Process The active force of all directions tends to balance state in certain interval, has fully ensured that the stability of processing so that punching course Can according to setting movement locus, the shell precision of processing is high, and that further improves shell carves conjunction tightness.
