The diameter of the main body 41 is greater than the width of the adhesive part 42. The film product 40 designed with a round head and a square tail is more convenient for attachment and assembly or peeling and tearing.

[0025] like Figures 3 to 7 As shown, the utility model also provides a forming mold 200 for an ultra-light release film product.

[0026] A molding die 200 for an ultra-light release film product is used for laminating and molding an ultra-light release film product 100, and comprises a bearing die base 50, a first laminating die 60 and two sets of second laminating die 70.

[0027] The bearing mold base 50 is provided with a bearing groove 51 with an upper end opening and extending to the left and right ends, and a pad 52 is also provided in the bearing groove 51. The first bonding mold 60 is located above the bearing mold base 50, and includes a positioning plate 61 and a bonding plate 62. The positioning plate 61 is provided with a mounting hole 611 penetrating from top to bottom. The bonding plate 62 is penetrated from top to bottom in the mounting hole 611 and its lower end extends to the bottom of the positioning plate 61. The bottom of the bonding plate 62 also corresponds to the bearing groove 51 from top to bottom. Two groups of the second bonding molds 70 are respectively axially connected to the front and rear sides of the bearing mold base 50, and include a flip template 71 and a plurality of pneumatic mold rods 72. The flip template 71 can be movably flipped and engaged in the bearing groove 51. The flip template 71 is also provided with a plurality of pneumatic holes 711 penetrating from top to bottom. The plurality of pneumatic mold rods 72 are respectively engaged in the plurality of pneumatic holes 711 and can be elastically lifted and lowered.

[0028] When the ultra-light release film product 100 needs to be assembled and pasted, a pad 52 of suitable thickness is first selected and installed in the bearing groove 51, and then the high-viscosity protective film 10 is aligned and pasted on the pad 52. Then, the pasting plate 62 with the ultra-light release film 20 and the slightly-viscosity protective film 30 pasted on the bottom is pasted in the bearing groove 51 and pressed down by the driving device, so that the ultra-light release film 20 and the slightly-viscosity protective film 30 are both pasted on the high-viscosity protective film 10. Then, the first pasting mold 60 is raised and reset, and then the second pasting mold 70 is driven to flip, so that the outer end of the flip template 71 is flipped and snapped into the bearing groove 51. After the flip template 71 is flipped and positioned, the air pressure mold rod 72 is pushed by the air pressure device to press the film product 40 in the air pressure hole 711 downward, so that it is simultaneously pasted on the ultra-light release film 20 and the slightly-viscosity protective film 30.

[0029] The first laminating mold 60 further includes a slide rail 63 and a pushing wheel 64. The bottom of the laminating plate 62 is designed as a convex arc structure, and a concave arc-shaped pushing groove 621 is provided at the upper end thereof, and arc-shaped limiters 622 are provided at the front and rear sides.
