The specific embodiment
See also Fig. 1 to Fig. 6, inventor of the present utility model be in order to understand the technical solution of the utility model better, below by embodiment particularly, and is described in detail by reference to the accompanying drawings:
See also Fig. 1 to Fig. 6, a kind of extrusion die that squeezes attached plastics for rubber surface of the present utility model, comprise horizontal support roller platform 4, the end of horizontal support roller platform 4 is provided with the gripper shoe 3 vertical with horizontal support roller platform 4 end faces, the second template 2 and the first template 1 successively.In the present embodiment, be bolted between gripper shoe 3, the second template 2 and the first template 1.Gripper shoe 3 is fixing by bolt and horizontal support roller platform 4.Also fixing by the alignment pin 6 that is positioned on the second template left side wall and right side wall between the 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, the first through holes 31 axially run 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 the 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, passes through gripper shoe 3 with what allow the plastic tape extruded or plastic sheeting from extruding machine.Extruding machine is fixed by the bolt blind hole 33 on gripper shoe 3 and the left side wall of gripper shoe 3.
The second template 2 is provided with the contour second mouthful of mould 21 in bottom surface and the first through hole 31 bottom surfaces, and to allow rubber pass through the second template 2, simultaneously, 21 pairs of rubber of second mouthful of mould position.Also be provided with the third through-hole 22 that is communicated with the second through hole 32 on the second template 2, to allow second template 2 of passing through of plastic tape or plastic sheeting.
The first template 1 is provided with the First mould 11 that overlaps 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 that connects third through-hole 22 outlets 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 are divided into two strands of plastic tapes or plastic sheeting in plastic passages 12, and enter respectively left location 121 and right location 122.Plastic tape in left location 121 or the plastic sheeting squeezed left side that is attached to rubber, the plastic tape in right location 122 or the plastic sheeting squeezed right side that is attached to rubber.By this design, can guarantee that plastic sheeting or plastic tape squeeze the left and right sides that is attached to rubber reposefully.
Need not the place of rubber extruding by up and down emptying on while second mouthful of mould 21 and First mould 11, can allow like this rubber unobstructed through second mouthful of mould 21 and First mould 11, by this design, can guarantee further that plastic sheeting or plastic tape squeeze the left and right sides that is attached to rubber reposefully.
A kind of improvement of squeezing the extrusion die maximum of attached plastics for rubber surface of the present utility model is: the front end face of the first template 1 is provided with the slack adjuster 5 of the below that is positioned at First mould 11, leaves height H adjustable gap between the end face of the end face of slack adjuster 5 and First mould 11.
The height H in this gap can not easily produce the rubber size refluence otherwise squeeze greater than 0.8mm in additive process, make the product shake, 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 the product bending, reduces the quality of product.The height in this gap is between 0.2～0.8mm the time, a kind of extrusion die for the crowded attached plastics of rubber surface of the present utility model can squeeze attached process at rubber surface with plastic tape or plastic sheeting, prevent that plastic sheeting or plastic tape from fractureing, improve plastic tape or plastic sheeting and squeeze attached continuity at rubber surface, prevent that rubber is excessive and crooked because being subject to resistance, thereby improve the quality of product.In the present embodiment, the height H in this gap is to regulate by the height adjustment bolt 51 that is positioned at slack adjuster 5 bottoms.
In addition, the first template 1 and the second template 2 all adopt the mould structure of up and down 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 illustrates the utility model, and be not to be used as restriction of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of above embodiment.
