Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot runner system technology, and in particular to a special type of dual-injection nozzle structure. Background Technology
[0002] Injection molding machines, also known as injection molding machines or injection machines, are the main molding equipment used to make various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. Injection molding machines heat the plastic and apply high pressure to the molten plastic, causing it to be injected and fill the mold cavity. The injection station of the injection molding machine is a key technology in the injection molding process and is a key component for injecting the molten plastic into the mold.
[0003] (see Figure 1 The traditional standard dual-shot main nozzle 10 includes a first main nozzle 11 and a second main nozzle 12. The first main nozzle 11 and the second main nozzle 12 are fixed side by side on the injection molding machine 20. When the injection molding machine 20 needs to inject two different materials, the materials being injected are easily interfered with because the distance between the first main nozzle 11 and the second main nozzle 12 is too small, which affects the material quality.
[0004] Therefore, through beneficial exploration and research, the applicant has found a solution to the above problems, and the technical solution to be introduced below is the result of this research. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a special dual-injection nozzle structure to address the above-mentioned shortcomings and defects of the existing technology.
[0006] The technical problem to be solved by this utility model can be achieved by the following technical solution:
[0007] A special type of dual-injection molding nozzle structure is characterized by comprising a dual-injection main nozzle structure disposed on a dual-injection molding machine for injection molding two materials. The dual-injection main nozzle structure includes a first main nozzle and a second main nozzle disposed on the dual-injection molding machine. The first main nozzle is arranged in a vertical structure, while the second main nozzle is arranged in an inclined structure.
[0008] In a preferred embodiment of the present invention, the dual-injection injection molding machine includes a two-injection manifold and a one-injection manifold connected to the first main nozzle and the second main nozzle. The two-injection manifold and the one-injection manifold are respectively provided with a first channel and a second channel communicating with the first main nozzle and the second main nozzle.
[0009] In a preferred embodiment of the present invention, the first main nozzle and the second main nozzle are respectively provided with a first flow channel and a second flow channel that communicate with the two-shot flow divider plate and the one-shot flow divider plate.
[0010] In a preferred embodiment of this utility model, the height of the first main nozzle is higher than the height of the second main nozzle, so that the first main nozzle and the second main nozzle are staggered to prevent interference.
[0011] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: Compared with the prior art, this utility model modifies the traditional parallel arrangement of dual injection main nozzles into a straight structure and an inclined structure, and sets the dual injection main nozzles in a staggered manner, thereby avoiding interference when the injection molding machine needs to inject two materials. Attached Figure Description
[0012] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0014] Figure 2 This is a schematic diagram of the structure of this utility model.
[0015] Figure 3 This is a top view of the present invention. Detailed Implementation
[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0017] See Figures 2 to 3 The illustration shows a special type of dual-injection molding nozzle structure, including a dual-injection main nozzle structure 20 mounted on a dual-injection molding machine 10 for injection molding two materials. The dual-injection main nozzle structure 20 includes a first main nozzle 21 and a second main nozzle 22 mounted on the dual-injection molding machine 10. The first main nozzle 21 is arranged vertically, while the second main nozzle 22 is arranged at an angle. In this embodiment, the height of the first main nozzle 21 is higher than the height of the second main nozzle 22, thus offsetting the first main nozzle 21 and the second main nozzle 22 to prevent interference.
[0018] To enable injection molding of two materials, the dual-injection injection molding machine 10 includes a two-injection manifold 11 and a one-injection manifold 12 connected to a first main nozzle 21 and a second main nozzle 22. The two-injection manifold 11 and the one-injection manifold 12 are respectively provided with a first channel and a second channel (not shown in the figure) communicating with the first main nozzle 21 and the second main nozzle 22. To enable injection molding with the dual-injection main nozzle structure, in this embodiment, the first main nozzle 21 and the second main nozzle 22 are respectively provided with a first flow channel 21a and a second flow channel 22a communicating with the two-injection manifold 11 and the one-injection manifold 12.
[0019] When this invention is used, if two materials need to be injected, the two-shot flow divider 11 and the one-shot flow divider 12 on the dual-shot injection molding machine 10 add the injection material, which then enters the first main nozzle 21 and the second main nozzle 22 through the first channel and the second channel, and finally flows into the first flow channel 21a and the second flow channel 22a of the first main nozzle 21 and the second main nozzle 22 to achieve dual-shot injection. Moreover, since the first main nozzle 21 and the second main nozzle 22 are arranged in a straight and oblique structure, the two materials will not interfere with each other.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
