Description

Double-color forming die Technical Field The utility model relates to the field of material forming, in particular to a double-color forming die. Background In the product appearance design, the adoption of the bicolor surface treatment can obviously improve the visual texture and the morphological diversity of the product. In the conventional structural member pattern shown in fig. 1, the upper part is a first color depth structure, the lower part is a second color depth structure, and the two structures are laminated to realize a color contrast effect. Such two-color configurations have wide application needs in the fields of consumer electronics, household articles, automotive interiors, and the like. In order to overcome the problem, the prior art generally adopts a step secondary molding process, namely, firstly, a second light-color structural component is molded in a first mold, then the second light-color structural component is transferred into a second mold to serve as an insert, and then, the first light-color structural component is molded on the surface of the second light-color structural component. The process can realize accurate control of the color separation interface, but has obvious disadvantages, namely the development of two independent molds is needed, the cost is high, and in addition, the period time is increased in the component transfer process. Disclosure of utility model The utility model provides a double-color forming die aiming at the problems of high cost and low component transfer efficiency of two sets of dies. The utility model provides a double-color forming die which comprises an upper die, a lower die and a spring plate, wherein the lower die is provided with a first imitation groove with a second color shallow structure, an insert is arranged on the upper die, after the upper die and the lower die are clamped, the lower part of the insert and the first profiling groove form a second color shallow structure, the middle part of the spring plate is provided with a through groove penetrating through the upper surface and the lower surface of the spring plate, the inner wall of the through groove is a profiling of the outer side edge of the first color deep structure, and during processing, the spring plate is positioned between the upper die and the lower die, after the upper die and the lower die are clamped, the through groove and the first imitation groove form a second imitation groove with the first color deep structure, and the insert and the second profiling groove form the first color deep structure. Preferably, the spring plate is arranged below the upper die, a limiting rod is arranged above the spring plate, a limiting hole is formed in the position, corresponding to the limiting rod, of the upper die, and the upper die is in sliding connection with the limiting rod through the limiting hole. The utility model provides a double-color forming die, which is used for completing double-color structure composite forming in sequence under the condition of single die filling, wherein a single die replaces a traditional double-die system, the equipment investment and maintenance cost are obviously reduced, double-color lamination forming is automatically completed through two die closing cycles, and the part transfer and die replacement flow is omitted. Additional aspects and advantages of the utility model will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the utility model. Drawings The foregoing and/or additional aspects and advantages of the present utility model will become apparent and readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings, in which: FIG. 1 is an illustration of a prior art bi-color structure; Fig. 2 is a block diagram of a two-color forming die provided by the utility model.
