Example Embodiment
[0032] Example one.
[0033] See figure 1 with figure 2 As shown, a cooling protection type multi-adhesive film injection molding process of the present invention includes the following steps:
[0034] A first adhesive film 1 and a second adhesive film 2 are provided. The first adhesive film 1 has a first body portion 12, the second adhesive film 2 has a second body portion 14, and the first body portion 12 and the second body portion 14 have For example, the color of the first body part 12 is silver, and the color of the second body part 14 is black. The patterns, graphics or colors of the first body part 12 and the second body part 14 are used, The car is decorated with graphics or colors, and the first adhesive film 1 and the second adhesive film 2 are combined to form a car logo 3;
[0035] Provide an injection mold 4, put the car logo 3 into the injection mold cavity of the injection mold 4, and the injection mold 4 has a glue inlet hole communicating with the injection mold ...
Example Embodiment
[0049] Example two
[0050] See figure 1 with figure 2 As shown, the cooling assembly 5 includes a cooling hole arranged on the injection mold 4, the cooling hole is used to communicate with the outside of the cooling device, the cooling device is used to input external cooling fluid (such as cooling liquid, cooling oil or Cooling gas, etc.), the cooling fluid passes through the injection mold 4 to cool the vehicle logo 3.
[0051] After the vehicle logo mark 3 is placed in the injection mold cavity, the injection mold 4 completes the mold clamping, and then the cooling device injects cooling fluid into the cooling hole, and the cooling fluid passes through the injection mold 4 to the first adhesive film 1 or the vehicle mark mark 3 / And the second adhesive film 2 are cooled, and then the molten plastic from the outside is injected into the injection mold cavity through the injection hole, and the cooling fluid is used to cool the vehicle logo 3 to prevent the first adhesive fil...
Example Embodiment
[0053] Example three
[0054] See figure 1 with figure 2 As shown, the first bonding edge 13 of the first adhesive film 1 and the second bonding edge 15 of the second adhesive film 2 are fixed together by glue, and the first adhesive film 1 and the second adhesive film are connected by glue. The film 2 is bonded and fixed together, which simplifies the fixing structure between the first bonding edge 13 and the second bonding edge 15, and improves the connection efficiency between the two bonding edges.
[0055] The rest of this embodiment is the same as the first embodiment, and the unexplained features in this embodiment adopt the explanation of the first embodiment, and will not be repeated here.
