Abstract
The utility model discloses a punching die, which is characterized in that the punching die comprises a substrate, a blade and a puncher, wherein the blade and the puncher are fixedly mounted on the substrate. As the puncher is mounted on the punching die, the punching die can simultaneously complete membrane exterior cutting and positioning-hole punching, effectively reduces processing procedures, and simultaneously increases precision of positions of positioning holes. As the punching die is provided with a waste ejecting device, the punching die prevents punched wastes blocking holes in the middles of cylindrical cutters. In addition, the punching die has the advantages of simple operation, high efficiency and the like.
Description
Technical field
The utility model relates to a kind of punching die, especially a kind of punching die that is used to cut LCD usefulness diaphragm.
Background technology
General use LCD (hereinafter to be referred as LCD) at notebook computer, LCD, LCD TV etc. to have gently, approach, lack with respect to cathode-ray tube display (CRT) and advantage such as power consumption is low, its demand is just in cumulative year after year.But LCD is different with CRT, and itself is not luminous, so must use the LCD backlight module, the light source that the LCD backlight module is provided sees through and is shown as image after the LCD panel is regulated.The prismatic lens that the LCD backlight module generally includes CCFL that light source is provided, make the homodisperse LGP of light, the diffusion sheet that is used to increase the light uniformity that light source penetrates, be used to change the direction of light and produce briliancy, prevent the reflector plate of light leak and the screening glass that shields.The LCD backlight module is that the order by reflector plate, LGP, diffusion sheet, prism, screening glass assembles.After the LCD backlight module installs, add a cover liquid crystal panel and be assembled into LCDs.The diaphragm that relates in whole packing engineering is more, and each diaphragm location is extremely important, in case the display quality that deviation will have a strong impact on LCDs occurs, so all be provided with the ear shape structure of location usefulness on each diaphragm, the locating hole of die-cut formation is wherein arranged.Generally use the die-cut locating hole of common cylinder cutter at present.This mode produces the die-cut circular waste material that gets off through regular meeting and is stuck in the middle hole of cylinder cutter, can not come off automatically, causes follow-up cutting to be broken down, thereby has a strong impact on diaphragm production.
The utility model content
Punching die of the present utility model has solved an above-mentioned difficult problem, and a kind of punching die that can automatically waste material be ejected is provided.
The technical solution of the utility model provides a kind of punching die, it is characterized in that: it comprises cylinder cutter and the waste material liftout attachment that is installed in the middle circular hole of described cylinder cutter.
Preferably, described waste material liftout attachment comprises spring, and described spring one end is connected with the bottom of described cylinder cutter, and the other end removably is provided with thimble.
Punching die of the present utility model has avoided die-cut waste material down to stop up the phenomenon of the hole of cylinder cutter centre because the waste material liftout attachment has been installed effectively.Have and use simple, good, the production efficiency advantages of higher of security.
Description of drawings
Fig. 1 is the structural representation of the utility model punching die.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, punching die of the present utility model comprises cylinder cutter 8 and the waste material liftout attachment 10 that is installed in the cylinder cutter 8 middle holes, and waste material liftout attachment 10 comprises spring 12, and spring 12 1 ends are fixed on the bottom of cylinder cutter 8, and the other end is connected with thimble 14.
Punching die of the present utility model is when work, cylinder cutter 8 is done die-cut operation to diaphragm to be cut under the driving of machine, the circular waste material that die-cut operation forms by extruding thimble 14, compresses the spring 12 of the waste material liftout attachment 10 that is positioned at cylinder cutter 8 centres in die-cut process.When die-cut operation is finished, cylinder cutter 8 is cut circular waste material open from diaphragm to be cut fully, this moment, external force disappeared, spring 12 is under the effect of elastic force, by thimble 14 centre of circular waste material from cylinder cutter 8 ejected, cylinder cutter 8 restores to the original state, thereby has avoided circular waste material to stop up the phenomenon of the middle hole of cylinder cutter 8.
Above embodiment only is the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
Claims (2)
1. punching die is characterized in that: it comprises the cylinder cutter and is installed in the waste material liftout attachment in the circular hole in the middle of the described cylinder cutter.
2. punching die according to claim 1 is characterized in that: described waste material liftout attachment comprises spring, and described spring one end is connected with the bottom of described cylinder cutter, and the other end removably is provided with thimble.
