The first injection lower die 1 and the second injection lower die 2 are oppositely arranged on the turntable 3; the injection molding mechanism 4 is arranged above the first injection molding lower die 1, the injection molding mechanism 4 is provided with an injection molding structure 401 and an injection molding upper die 402, and the injection molding structure 401 is in driving connection with the injection molding upper die 402; the gum material belt conveying mechanism 5 is arranged above the second injection lower die 2; the pressing mechanism 6 is arranged above the back adhesive tape conveying mechanism 5, and the pressing mechanism 6 is provided with a pressing part 601, a connecting part 602 and a pressing driving cylinder 603; the press-fit portion 601 is connected below the connecting portion 602, and the press-fit driving cylinder 603 is in driving connection with the press-fit portion 601.

Specifically, the first injection lower mold 1 and the second injection lower mold 2 have the same structure, and the first injection lower mold 1 and the second injection lower mold 2 are disposed opposite to each other on two sides of the turntable 3, that is, when the turntable 3 rotates 180 degrees around its own rotation axis, the first injection lower mold 1 and the second injection lower mold 2 can exchange positions with each other, that is, when the turntable 3 rotates 180 degrees, the first injection lower mold 1 follows the rotation of the turntable 3 to reach the original position of the second injection lower mold 1; and the second injection lower die 2 reaches the original position of the first injection lower die 1 at the same time. Further, the injection molding mechanism 4, the gum material belt conveying mechanism 5 and the pressing mechanism 6 are not directly connected with the turntable 3, that is, when the turntable 3 rotates, the relative positions among the injection molding mechanism 4, the gum material belt conveying mechanism 5 and the pressing mechanism 6 are not changed. The injection structure 401 of the injection mechanism 4 is a related structure of a conventional vertical injection molding machine in the prior art, that is, the injection structure 401 includes modules such as an injection system, a hydraulic transmission system, an electrical control system, and a heating or cooling system, which are necessary for implementing an injection process. The injection molding structure 401 is in driving connection with the injection molding upper die 402, and the injection molding upper die 402 can be respectively in matched die clamping connection with the first injection molding lower die 1 or the second injection molding lower die 2 which rotate to the lower side along with the turntable 3. More specifically, the injection molding mechanism 4 is a mechanism in conventional injection molding equipment, in which an injection molding lower mold is separately removed and an upper mold is maintained.

Further, the gum material belt conveying mechanism 5 may convey the gum material belt pre-placed therein so that the gum material to be adhered to the surface of the injection molding member may be conveyed above the first injection lower mold 1 or the second injection lower mold 2. Specifically, the gum material belt conveying mechanism 5 has a gum material feeding frame 501, a gum material conveying rail 502, and a gum material traction mechanism 503. The gum feeding frame 501 is arranged at the outer side of the turntable 3; the gum transfer rail 502 is disposed between the press portion 601 and the second injection lower mold 2; the gum traction mechanism 503 is disposed on the other side of the turntable 3 with respect to the gum incoming frame 501. More specifically, a user may guide the back-up material to be processed through the back-up feeding frame 501 into the back-up conveying rail 502 in advance. The gum transfer rail 502 is disposed above the turntable 3, and the gum transfer rail 502 may pull the gum roll to be processed from the gum feeding frame 501 and guide the gum roll to cross the turntable 3, and then insert the gum roll into the gum traction mechanism 503. In addition, the back adhesive conveying track 502 leaves a gap under the pressing part 601, which is matched with the pressing part 601, so that the pressing part 601 presses the back adhesive tape down to be fully abutted with the injection molding piece on the second injection lower die 2.

Further, a backing substrate reel 504 may be further disposed below the backing supply rack 501, and the backing substrate reel 504 is movably connected with the backing supply rack 501. Specifically, conventional double-sided backsize generally includes two substrate layers and a glue layer disposed between the two substrate layers. Because both sides of the adhesive layer have tackiness, in order to facilitate its turnover, it is generally necessary to protect the adhesive layer with two substrate layers before using the adhesive layer to avoid the adhesive layer losing tackiness or being stained with debris during the turnover process. Therefore, before the bonding portion 601 bonds the back adhesive to the injection molding, a bottom substrate layer needs to be removed in advance. Thus, a backing substrate reel 504 may be movably connected below the backing supply frame 501, and the backing substrate reel 504 may rotate around itself below the backing supply frame 501. Therefore, before the bonding portion 601 bonds the adhesive to the injection molding, the bottom substrate layer of the adhesive may be peeled off and wound into the adhesive-backed substrate reel 504. The backing substrate reel 504 may also continuously collect the bottom-most substrate layer as rolls while the backing traction mechanism 503 continues to draw the backing tape.

FIG. 4 is a schematic view of an injection molding product manufactured by the injection molding and back adhesive integrated device of the present utility model; FIG. 5 is a schematic illustration of the structure of a gum material strip stock; fig. 6 is a schematic structural view of a gum material belt with injection molding products after processing by the injection molding and gum material integrated device of the present utility model. When the injection molding and back glue integrating device works, the injection molding structure 401 drives the injection molding upper die 402 to downwards move to be matched with the first injection molding lower die 1, and after the injection molding upper die 402 is separated from the first injection molding lower die 1, a plurality of injection molding products a are reserved on the first injection molding lower die 1. Then, carousel 3 rotatory 180 degrees, first lower mould 1 of moulding plastics with the second lower mould 2 of moulding plastics exchange the position, pressfitting drive cylinder 603 drive pressfitting portion 601 descends, pressfitting portion 601 promotes gum transfer track 502 and gum material area raw materials b descend simultaneously, until gum material area raw materials b with be located a plurality of injection molding product a of first lower mould 1 top all fully butt to make all injection molding product a all pasted to gum material area raw materials b's below. At the same time, the injection structure 401 drives the injection upper die 402 to move down again to be clamped with the second injection lower die 2, so that a plurality of injection products a are also processed on the second injection lower die 2. The gum material belt conveying mechanism 5 then drives the gum material belt raw material b adhered with the injection molding product a to continue to move down to the next station, and simultaneously conveys the new gum material belt raw material b not adhered with the injection molding product a to the lower part of the pressing mechanism 6. Then, the turntable 3 is rotated again by 180 degrees so that the actions of injection molding the product and sticking the back adhesive are circulated.
