Now lifting following examples also is elaborated to structure of the present invention, characteristics and effect in conjunction with the accompanying drawings.
At first, as Fig. 2, shown in Figure 3, ejaculation mould 100 for the tool cutting structure that a preferred embodiment of the present invention provided, mould 100 comprises one first module 10, one second module 20 and a cutting blade spare 30, mould 100 is to use in in-mould thin film connecting shaping manufacture process, make film F can be in advance in mould 100 inside cut processing through preposition, the structure of mould 100 that present embodiment now is described in detail in detail is as follows:
As Fig. 2～shown in Figure 5, first module 10 is in the present embodiment for being connected in an ejaculator (not shown), it has a die joint 11 and a tab-like die 12 that is formed in die joint 11, die 12 peripheries are around being provided with an annular slot 121, in addition, first module, 10 central authorities are provided with an injection channel 10a and are incident upon mould 100 inside for the plastics of ejaculator.
Cutting blade spare 30 is an annular framework at present embodiment, the one end is fastened in the annular slot 121 of die 12 peripheries of first module 10, the other end protrudes into outside the die 12, and form a blade 31, in the present embodiment, the length of blade 31 is greater than the thickness of film F, and its front end forms a beveled end 311, beveled end 311 near the height of a side of die cavities 101 less than height away from a side of die cavity 101.When first, second module 10,20 closures, cutting blade spare 30 is positioned at die cavity 101, and be close to the internal face 221 of the die cavity 22 of second module 20, its blade 31 stretches into the cutter groove 22a of die cavity 22, fully film F being cut off, and blade 31 pastes together near a side wall surface of die cavities 101 internal face 221 with the die cavity 22 of second module 20.
What must illustrate is that the draw-in groove 121 of first module 10 is not necessary assembly, can omit.In other words, cutting blade spare 30 can be used die 12 peripheries that integrated mode is formed at first module 10 instead.In addition, cutting blade spare 30 also can be movable, promptly, the operator can change the suitable cutting blade spare of length 30 according to the thickness of film F, or the fine setting by the guiding mechanism (not shown) makes cutting blade spare 30 produce displacements, to change the length of blade 31, can cooperate the film of different-thickness to use thus.And the shape of cutting blade spare 30 also not only is confined to above-mentioned annular framework.
More than be mould 100 each member of present embodiment and the explanation of relevant position thereof, then narrate it and apply to in-mould thin film connecting shaping manufacture process and effect that is produced and advantage:
As shown in Figure 2, when first, second module 10,20 is in opening, film F utilizes a clamping device 200 to insert in the mould 100 earlier, locate by clamping piece 23 clampings again, make the film F periphery all by the clamping packing, treat clamping piece 23 clamping film F after, clamping device 200 pine oil film F also withdraw to mould 100 outsides, then, film F is heated and is extended and be subjected to vacuum attraction and adhere well to die cavity 22 internal faces 221.Then, shown in the action flow chart of Fig. 4, Fig. 5 and Fig. 6 to Fig. 8, when first, second module 10,20 is operated closure, film F and cutting blade spare 30 are inconsistent and cut, must explanation be, in the present embodiment because blade 31 length of cutting blade spare 30 are greater than the thickness of film F, so film F can be completely severed, just burr can be taken advantage of a situation and are removed.Certainly, the operator also can adopt blade length to equal the cutting blade spare 30 of film F, so can reach identical purpose equally, and the cutter groove 22a of die cavity 22 also can save and do not establish.After having cut film F, plastics S enters along the injection channel 10a of first module 10, and with the film F connecting shaping in die cavity 101, last, carry out the die sinking operation, first, second module 10,20 is opened relatively, can obtain finished product 300 as shown in Figure 9, what should be specified is to be removed because the burr of film F are taken advantage of a situation in advance, so finished product 300 peripheries 301 do not have the film burr, therefore must can not obtain high accuracy and high surface structure attractive in appearance through secondary operations again.
Certainly, the length of the blade 31 of cutting blade spare 30 also can be less than the thickness of film F, promptly be as shown in figure 10, thus, the cutter groove 22a of second module 20 of the foregoing description also can save, in addition, blade 31 beveled ends 311 also can be near the height of a side of die cavity 101 greater than height away from a side of die cavity 101, so can reach the purpose that prevents flash equally.By said structure as can be known, after the mould closure, film F is not completely severed, so behind ejection formation, can obtain finished product 400 as shown in figure 11, because film F is in advance through appropriate cutting, therefore, the operator only needs the film F of finished product 400 peripheries 401 application of force a little, it can be taken off, can obtain high accuracy and high product attractive in appearance equally.
What deserves to be mentioned is that in addition the design of the blade 31 of tool beveled end 311 of the present invention is except that can reaching preferably cutting effect, more can be when plastics penetrate, plastics are blocked in mould 100 die cavities 101, avoid taking place flash situation of the prior art, to improve the exquisite degree and the aesthetics of finished product.Moreover, because internal face 221 subsides of the die cavity 22 of a side wall surface of blade 31 close die cavities 101 and second module 20 are neat, thus the precision that cuts is more improved, to improve the exquisite degree and the aesthetics of finished product.
In sum, the present invention directly utilizes the cutting blade spare 30 in the mould 100 that film F is carried out the preposition operation that cuts, make that film F burr ratio is easier to take off around the finished product 300 after the moulding, or utilize blade 31 than the long cutting blade spare of the thickness of the film F removal burr of directly taking advantage of a situation when mould 100 matched moulds, thus, than the person of commonly using, the design of cutting blade spare of the present invention can significantly reduce or save the secondary processing cost that the follow-up burr cutting operation of commonly using decorating film is caused, can save a large amount of manpowers, time and equipment cost, and the production efficiency height, and do not have commonly use the uneven situation that the film burr around the finished product are produced after pruning.Therefore, utilize the prepared finished product of mould of the present invention to have high exquisite degree and aesthetic property, have high commercial interest and surcharge.
