Detailed description of the invention
Refer to Fig. 1 to Fig. 6, the present inventor, in order to understand technical scheme of the present invention better, below by embodiment particularly, and is described in detail by reference to the accompanying drawings:
Refer to Fig. 1 to Fig. 6, a kind of extrusion die squeezing attached plastics for rubber surface of the present invention, comprises horizontal support roller platform 4, and the end of horizontal support roller platform 4 is provided with gripper shoe 3, second template 2 vertical with horizontal support roller platform 4 end face and the first template 1 successively.In the present embodiment, be bolted between gripper shoe 3, second template 2 and the first template 1.Gripper shoe 3 is fixed by bolt and horizontal support roller platform 4.Also fixed by the alignment pin 6 be positioned on the second template left side wall and right side wall between second template 2 and the first template 1.
Gripper shoe 3 is provided with the first through hole 31 and the second through hole 32, first through hole 31 and axially runs through gripper shoe 3, and the end face of the bottom surface of the first through hole 31 and horizontal support roller platform 4 is contour, to allow rubber on horizontal support roller platform 4 by gripper shoe 3.One end of second through hole 32 is positioned on the left side wall of gripper shoe 3, and the other end of the second through hole 32 is positioned on the front end face of gripper shoe 3, with allow the plastic tape extruded from extruding machine or plastic sheeting by gripper shoe 3.Extruding machine is fixed with the left side wall of gripper shoe 3 by the bolt blind hole 33 in gripper shoe 3.
Second template 2 is provided with the contour second mouthful of mould 21 in bottom surface and the first through hole 31 bottom surface, and to allow rubber by the second template 2, meanwhile, second mouthful of mould, 21 pairs of rubber position.Second template 2 is also provided with the third through-hole 22 be communicated with the second through hole 32, with allow plastic tape or plastic sheeting by the second template 2.
First template 1 is provided with the first mould 11 overlapped with second mouthful of mould 21.The rear end face of the first template 1 is provided with the plastic passages 12 of the end face connecting third through-hole 22 outlet and first mould 11.The end of plastic passages 12 is divided into left location 121 and right location 122.In the present embodiment, plastic tape or plastic sheeting enter plastic passages 12 after flowing out from third through-hole 22, and in plastic passages 12, be divided into two strands of plastic tapes or plastic sheeting, and enter left location 121 and right location 122 respectively.Plastic tape in left location 121 or the squeezed left side being attached to rubber of plastic sheeting, the plastic tape in right location 122 or the squeezed right side being attached to rubber of plastic sheeting.By this design, can ensure that plastic sheeting or plastic tape squeeze the left and right sides being attached to rubber reposefully.
Simultaneously on second mouthful of mould 21 and first mould 11 without the need to the place of rubber extruding by upper and lower emptying, rubber can be allowed so unobstructed through second mouthful of mould 21 and first mould 11, by this design, can ensure that plastic sheeting or plastic tape squeeze the left and right sides being attached to rubber reposefully further.
A kind of improvement of squeezing the extrusion die of attached plastics maximum for rubber surface of the present invention is: the front end face of the first template 1 is provided with the slack adjuster 5 of the below being positioned at first mould 11, leaves the adjustable gap of height H between the end face of slack adjuster 5 and the end face of first mould 11.
The height H in this gap can not be greater than 0.8mm, otherwise squeezes easily generation rubber size refluence in additive process, and product is shaken, and plastic tape or plastic sheeting easily fracture; The height in this gap is less than 0.2mm, and the resistance that rubber is subject to is excessive, easily produces product and bends, reduce the quality of product.When the height in this gap is between 0.2 ~ 0.8mm, plastic tape or plastic sheeting can squeeze in attached process at rubber surface by a kind of extrusion die squeezing attached plastics for rubber surface of the present invention, prevent plastic sheeting or plastic tape from fractureing, raising plastic tape or plastic sheeting squeeze attached continuity at rubber surface, prevent rubber excessive and bending because being subject to resistance, thus improve the quality of product.In the present embodiment, the height H in this gap is that height adjustment bolt 51 by being positioned at slack adjuster 5 bottom carries out regulating.
In addition, the first template 1 and the second template 2 all adopt the mould structure of upper and lower two halves, the traction work of be more convenient for mold cleaning and dismounting and rubber strip.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the present invention is described, and be not used as limitation of the invention, as long as in spirit of the present invention, all will drop in Claims scope of the present invention the change of above embodiment, modification.
