Abstract
The utility model discloses a mould easy for separating a membrane, which comprises a substrate, a cutting blade and a folding line blade, wherein the cutting blade and the folding line blade are detachably installed on the substrate. The mould easy for separating the membrane is characterized in that an elastic device is further detachably installed on the substrate. As the elastic device is installed between the cutting blade and the folding line blade, the elastic device is compressed by squeezing of the membrane when the mould easy for separating the membrane is in cutting work, and the elastic device acts to spring away the membrane after cutting is finished, thereby the membrane is prevented from being clamped on the mould, and the mould has the advantage of high production efficiency.
Description
Technical field
The utility model relates to a kind of mould of easy Separation membrane, especially a kind of mould that is used to cut LCD with the easy Separation membrane of 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.Produce the phenomenon that certain slit produces light leak for fear of LGP edge and reflector plate, the edge of diffusion sheet and reflector plate is folding by certain angle, so need cut out the fold line of interruption during membrane cutting.Profile cutting knife and fold line cutting knife on the membrane cutting mould are arranged in parallel usually, distance between them is less, this makes this mould in use, occur sometimes clamping diaphragm between profile cutting knife and the fold line cutting knife, make the phenomenon that the diaphragm that processes can not normal separation, the processing of must stopping has a strong impact on production efficiency, influences product quality.
The utility model content
The mould of easy Separation membrane of the present utility model has solved an above-mentioned difficult problem, the mould that provides a kind of diaphragm that utilizes elastic force apparatus to cut to eject from mould automatically.
The technical solution of the utility model provides a kind of mould of easy Separation membrane, comprises substrate and detachably be installed in cutting blade and fold line blade on the described substrate, and it is characterized in that: described substrate also removably is equipped with elastic device.
Preferably, described elastic device comprises being installed in and cuts several spring assemblies in the middle of blade and the fold line blade and be installed in several arc elastomeric materials that cut the blade inboard.
Preferably, describedly be provided with several installing holes in the middle of cutting blade and fold line blade, the line between the described installing hole is parallel with the described length direction that cuts blade or described fold line blade, and described spring assembly is removably mounted in the described installing hole.
Preferably, described spring assembly comprises spring and the thimble that is fixed on described spring one end.
Preferably, described arc elastomeric material is a strip, and upper surface is an arc, height and shown in cut blade point of a knife equate to the height of described substrate, equidistant each other, parallel and parallel with described one side that cuts blade.
The mould of easy Separation membrane of the present utility model is owing to installed elastic device cutting between blade and the fold line blade, when cutting operation, elastic device is subjected to the extruding of diaphragm and compresses, cut finish after, elastic device is had an effect, diaphragm is flicked, thereby avoided diaphragm to be stuck on the mould, have advantage of high production efficiency.
Description of drawings
Fig. 1 is the structural representation of the mould of the easy Separation membrane of the utility model;
Fig. 2 is the cutaway view of piercer of mould of the easy Separation membrane of the utility model preferred embodiment shown in Figure 1.
Fig. 3 is the view in transverse section of Fig. 1.
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, the mould of the easy Separation membrane of the utility model preferred embodiment comprises substrate 8, removably is equipped with on the substrate 8 to cut blade 10 and fold line blade 12.Be provided with several installing holes (not shown) in the middle of cutting blade 10 and fold line blade 12, elastic device 14 is removably mounted in the installing hole, and cutting blade 10 installed inside has several arc elastomeric materials 16.
As shown in Figure 2, spring assembly 14 is installed in the installing hole 22 that cuts blade 10 and fold line blade 12 centres, and spring assembly 14 comprises spring 18 and thimble 20.Installing hole 22 internal diameters are bigger than the internal diameter of spring 18, and the internal diameter in exit is littler than the internal diameter of spring 18, internal diameter than thimble 20 is big, spring 18 just in time can be installed in the installing hole 22 like this, can from installing hole, not come off again, thimble 20 stretches out from the exit of installing hole 22, and the height that the aspect ratio of stretching out cuts blade 10 or fold line blade 12 is high slightly.
As shown in Figure 3, arc elastomeric material 16 upper surfaces are arc, and height is identical with the height that cuts blade 10.
The mould of easy Separation membrane of the present utility model is when cutting operation, and spring assembly 14 and arc elastomeric material 16 are subjected to the extruding of mould and are out of shape, and waits to cut operation when finishing, mould unclamps, under the elastic force effect, diaphragm is flicked, thereby avoided diaphragm to be stuck in phenomenon on the mould.
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.
