Technical Field
[0001] This utility model relates to the field of hot runner system technology, and in particular to a hot runner main nozzle structure that can switch between single-cavity or dual-cavity configurations. Background Technology
[0002] (see Figure 1 Traditional hot runner systems use two sets, with two main nozzles 1 and 2 on each set. Each main nozzle 1 and 2 is equipped with a feed inlet 1a and 2a. Therefore, two machines are needed to cooperate with two sets of molds for production, which increases costs and reduces work efficiency.
[0003] 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
[0004] The technical problem to be solved by this utility model is to provide a switchable single-cavity or dual-cavity hot runner main nozzle structure to address the above-mentioned shortcomings and defects of the prior art.
[0005] The technical problem to be solved by this utility model can be achieved by the following technical solution:
[0006] A switchable single-cavity or dual-cavity hot runner main nozzle structure includes a main nozzle structure disposed on a hot runner system. The main nozzle structure comprises a main nozzle head insert and a main nozzle tail insert detachably connected to the main nozzle head insert. The main nozzle head insert has an inlet port, and the interior of the main nozzle head insert has at least one inlet channel communicating with the inlet port. The interior of the main nozzle tail insert has an outlet channel communicating with the inlet channel, and the main nozzle tail insert has an outlet port communicating with the outlet channel.
[0007] In a preferred embodiment of the present invention, the feeding channel is a single feeding channel, which is disposed inside the main nozzle head insert and is connected to the feeding port and the discharging channel respectively.
[0008] In a preferred embodiment of this utility model, the feeding channel is a dual feeding channel, which is disposed inside the main nozzle head insert and is respectively connected to the feeding port and the discharging channel.
[0009] In a preferred embodiment of this utility model, the main nozzle head insert is pressed into the plane of the main nozzle tail insert, and a sealing ring is installed on the mating surface between the main nozzle head insert and the main nozzle tail insert.
[0010] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: This utility model can be used to produce on one machine with one set of molds, and the switching between single inlet and dual inlet can be achieved by changing the main nozzle head insert, thereby reducing costs and improving work efficiency.

[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 4 The illustrated hot runner main nozzle structure, which can switch between single-cavity and dual-cavity configurations, includes a main nozzle structure 10 disposed on a hot runner system. The main nozzle structure 10 includes a main nozzle head insert 11 and a main nozzle tail insert 12 detachably connected to the main nozzle head insert 11. In this embodiment, the main nozzle head insert 11 is press-fitted into the plane of the main nozzle tail insert 12, and a sealing ring is installed on the mating surface between the main nozzle head insert 11 and the main nozzle tail insert 12. The sealing ring is installed to prevent leakage.
[0018] The main nozzle head insert 11 is provided with a feed port 11a, and the interior of the main nozzle head insert 11 is provided with at least one feed channel 11b communicating with the feed port 11a. The interior of the main nozzle tail insert 12 is provided with a discharge channel 12a communicating with the feed channel 11b, and the main nozzle tail insert 12 is provided with a discharge port 12b communicating with the discharge channel 12a.
[0019] (See also:) Figure 2When the main nozzle head insert adopts a single cavity, the feed channel 11b in this embodiment is preferably a single feed channel. The single feed channel is set inside the main nozzle head insert 11 and is connected to the feed port 11a and the discharge channel 12a respectively.
[0020] (See also:) Figure 3 When the main nozzle head insert adopts a double cavity, the feeding channel in this embodiment is preferably a double inlet channel. The double inlet channel is set inside the main nozzle head insert 11 and is respectively connected to the inlet 11a and the outlet channel 12b.
[0021] In use, the main nozzle head insert 11 is pressed into the main nozzle tail insert 12 for planar fit. A sealing ring is installed on the mating surface between the main nozzle head insert 11 and the main nozzle tail insert 12 to prevent leakage. When changing the number of production cavities in the mold, the main nozzle head insert 11 can be removed and replaced with the required head insert, thereby achieving the switching between single inlet and dual inlet use, thus reducing costs and improving work efficiency.
