[0022] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technical personnel in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other, refer to Figure 1-4 .
[0023] The utility model provides:
[0024] A structure for attaching a flexible sheet in a blow mold comprises a blow molded part 1 and an injection molded part 2. The blow molded part 1 is provided with a mounting recess 11 on its surface. The injection molded part 2 is an injection-molded flexible part, and the injection molded part 2 is arranged at the mounting recess 11 of the blow molded part 1. When used, the injection molded part 2 is injection-molded in the blow molded part mold. After the injection molded part 2 is injection-molded, the injection molded part 2 forms a required pattern such as a logo and a word mark, thereby avoiding printing a logo and a word mark on the blow molded part 1, effectively reducing the production difficulty, avoiding the technical problem of the need to repeatedly print a pattern on the blow molded part 1 in the prior art, and greatly reducing the labor cost. Among them, the injection molded part 2 is a flexible integrated injection molded sheet. The use of a flexible injection molded part 2 can make the shape of the injection molded part 2 adapt to the mounting recess 11 of the blow molded part 1, and has high application flexibility. When used, whether it is an arc surface or other uneven surfaces, different sheets such as logos and word marks can be intactly attached to the surface of the blow-molded product.
[0025] Furthermore, the mounting recess 11 of the blow molded part 1 has an arc-shaped structure or a U-shaped structure at its edge, and after the injection molded part 2 is fixed to the mounting recess 11, the edge of the injection molded part 2 is clearance-matched with the arc-shaped structure or the U-shaped structure at the edge of the mounting recess 11. Through this clearance-matched structural design, a gap can be left between the edge of the mounting recess 11 and the edge of the injection molded part 2, preventing the molded part 2 from being damaged during the shrinkage process, which is beneficial to protecting the product.
[0026] Furthermore, the inner wall surface of the injection molded part 2 is fixed to the bottom surface of the mounting recess 11. Since the injection molded part 2 is a flexible integral injection molded sheet, after the injection molded part 2 is fixed to the mounting recess 11, the outer contour of the injection molded part 2 is kept approximately consistent with the inner contour of the mounting recess 11 by utilizing the flexible deformation performance of the injection molded part 2. For example, for the curved surface of the plastic product, after the injection molded part 2 is attached, the injection molded part 2 is also curved as a whole.
[0027] Furthermore, the blow molded part 1 is provided with one or more mounting recesses 11, and one or more injection molded parts 2 are mounted in the one or more mounting recesses 11. When there are multiple mounting recesses 11 provided on the blow molded part 1, the sizes and shapes of the multiple mounting recesses 11 can be the same or different, the shapes of the multiple injection molded parts 2 can be the same or different, and the multiple injection molded parts 2 can be fixed in the multiple mounting recesses 11 accordingly.
[0028] In this embodiment, the blow molded part 1 is an integral blow molded component. The blow molded part 1 is an integral hollow cylinder, and the mounting recess 11 is arranged on the outer side wall of the hollow cylinder. In this embodiment, there are two mounting recesses 11, and the two mounting recesses 11 are symmetrically distributed on the two outer wall surfaces of the hollow cylinder. There are two injection molded parts 2, and the two injection molded parts 2 are correspondingly mounted in the two mounting recesses 11.
[0029] Based on the above-mentioned structure of the soft sheet in the blow mold, the utility model also provides:
[0030] A plastic product comprises the structure of the soft sheet material pasted in the blow molding mold.
[0031] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
