根据实际需要，第一胶膜4与第二胶膜8之间、第一胶膜4与第三胶膜9之间可以有间隙，也可以没有间隙，当第一胶膜4与第二胶膜8之间、第一胶膜4与第三胶膜9之间具有间隙时，第二公模5或第二母模6设有突伸入第二模腔7内的隔离条，隔离条突伸入第一胶膜4与第二胶膜8之间、第一胶膜4与第三胶膜9之间，第二胶膜8、第三胶膜9、胶膜单元11在第二模腔7内注塑成型时，隔离条限位挡止相邻的两个胶膜，避免第二胶膜8、第三胶膜9发生变向而导致相邻两个胶膜接触贴合在一起。According to actual needs, there may or may not be gaps between the first adhesive film 4 and the second adhesive film 8, and between the first adhesive film 4 and the third adhesive film 9. When the first adhesive film 4 and the second adhesive film 9 When there is a gap between the films 8 and between the first adhesive film 4 and the third adhesive film 9, the second male mold 5 or the second female mold 6 is provided with a spacer bar protruding into the second mold cavity 7. The spacer bar It protrudes between the first adhesive film 4 and the second adhesive film 8, and between the first adhesive film 4 and the third adhesive film 9. The second adhesive film 8, the third adhesive film 9, and the adhesive film unit 11 are in the second adhesive film. During injection molding in the mold cavity 7, the spacer bar stops the two adjacent adhesive films, so as to prevent the second adhesive film 8 and the third adhesive film 9 from changing directions and causing the adjacent two adhesive films to contact and stick together. .
还包括如下步骤：It also includes the following steps:
提供吸塑模具，吸塑模具上设置有加热单元，吸塑模具设置有用于容设胶膜基材的吸塑模腔，使用时，先将胶膜基材放入吸塑模腔内，加热单元用于加热吸塑模腔内的胶膜基材使得胶膜基材软化，然后外界的抽气装置或真空发生装置对吸塑模腔进行抽气，利用吸塑模具对软化后的胶膜基材进行吸塑处理，使得胶膜基材吸塑定型成为第一胶膜4、第二胶膜8、第三胶膜9，使得第一胶膜4、第二胶膜8、第三胶膜9快速形成所需的形状构造，辅助提升胶膜饰件的生产效率。Provide a blister mold, the blister mold is provided with a heating unit, and the blister mold is provided with a blister mold cavity for accommodating the plastic film base material. The unit is used to heat the plastic film substrate in the plastic mold cavity to soften the plastic film substrate, and then the external air suction device or vacuum generating device will pump the plastic mold cavity, and the softened plastic film will be evacuated by the plastic plastic mold. The substrate is subjected to blister treatment, so that the adhesive film substrate is blistered and shaped into the first adhesive film 4, the second adhesive film 8, and the third adhesive film 9, so that the first adhesive film 4, the second adhesive film 8, and the third adhesive film are formed. The film 9 can be quickly formed into the required shape structure, which helps to improve the production efficiency of the plastic film trim.
还包括如下步骤：It also includes the following steps:
提供裁切组件，裁切组件对吸塑模具吸塑定型后的第一胶膜4、第二胶膜8、第三胶膜9进行裁切处理，利用裁切组件切除第一胶膜4、第二胶膜8、第三胶膜9的边料及余料，裁切组件裁切后的第一胶膜4放入第一模腔3内进行一次注塑，裁切组件裁切后的第二胶膜8、第三胶膜9放入第二模腔7内进行二次注塑。A cutting assembly is provided. The cutting assembly performs cutting processing on the first adhesive film 4, the second adhesive film 8, and the third adhesive film 9 after the blister mold is blistered and shaped, and the first adhesive film 4, The leftover material and the remaining material of the second adhesive film 8 and the third adhesive film 9, the first adhesive film 4 cut by the cutting assembly is put into the first mold cavity 3 for one injection, and the second adhesive film after being cut by the cutting assembly The adhesive film 8 and the third adhesive film 9 are put into the second mold cavity 7 for secondary injection.
优选地，所述裁切组件包括安装设置在吸塑模具上的驱动件、与驱动件的输出端连接的裁切刀，驱动件驱动裁切刀对吸塑模具吸塑定型后的第一胶膜4、第二胶膜8、第三胶膜9进行裁切。Preferably, the cutting assembly includes a driving member installed on the suction mold, a cutting knife connected to the output end of the driving member, and the driving member drives the cutting knife to form the first glue after the suction mold is formed by suction. The film 4, the second adhesive film 8, and the third adhesive film 9 are cut.
当吸塑模具经由吸塑成型制得第一胶膜4、第二胶膜8、第三胶膜9后，驱动件驱动裁切刀移动，利用移动的裁切刀对吸塑模腔内的第一胶膜4、第二胶膜8、第三胶膜9进行裁切，相较于将第一胶膜4、第二胶膜8、第三胶膜9从吸塑模腔内移出后再进行裁切，无需对第一胶膜4、第二胶膜8、第三胶膜9进行二次定位，提升第一胶膜4、第二胶膜8、第三胶膜9的裁切效率及裁切良率。When the first adhesive film 4, the second adhesive film 8, and the third adhesive film 9 are formed by the blister mold through blister molding, the driving member drives the cutting knife to move, and the moving cutting knife is used to align the plastic film in the blister mold cavity. The first adhesive film 4 , the second adhesive film 8 , and the third adhesive film 9 are cut, compared with the first adhesive film 4 , the second adhesive film 8 , and the third adhesive film 9 being removed from the blister mold cavity. After cutting, there is no need to reposition the first adhesive film 4 , the second adhesive film 8 , and the third adhesive film 9 to improve the cutting of the first adhesive film 4 , the second adhesive film 8 , and the third adhesive film 9 . Efficiency and cutting yield.
实施例二Embodiment 2
所述第一胶膜4的装饰层、第二胶膜8的装饰层、第三胶膜9的装饰层彼此均不相同，例如，第一胶膜4的装饰层为银色，第二胶膜8的装饰层为红色，第三胶膜9的装饰层均为黑色，此时整个胶膜饰件为三色构件。The decorative layer of the first adhesive film 4 , the decorative layer of the second adhesive film 8 , and the decorative layer of the third adhesive film 9 are all different from each other. For example, the decorative layer of the first adhesive film 4 is silver, and the second adhesive film is silver. The decorative layer of 8 is red, and the decorative layer of the third adhesive film 9 is black. At this time, the entire adhesive film trim is a three-color component.
