Description

Technical Field

[0001] This utility model relates to the field of mold cooling technology, and in particular to a novel conformal sealing water tank cooling structure. Background Technology

[0002] Hot runner is a key structure in injection molds, used to inject molten material into the mold. Because the material needs to be kept in a molten state, its temperature is relatively high. After the material is injected into the mold, a cooling system is used to cool and solidify it.

[0003] like Figures 1-3 The diagram shows the existing hot runner 1 and its cooling water pipes 2. Since the front mold section of the injection molded product 6 has a relatively small structure, it is a critical part for cooling the product. Evenly distributed cooling water pipes can effectively reduce product deformation and molding cycle time. When the mold has a hot runner system and the hot runner does not directly inject glue onto the product surface, a cooling water jacket is not necessary; only cooling water pipes need to pass around the perimeter. When the product is large, the diameter D of the clearance hole for the hot runner 3 reaches 55-60mm. To avoid the hot runner and allow a certain safety distance, the spacing H1 of the cooling water pipes needs to be at least 85mm. The ideal spacing for the cooling water pipes is 5 times their diameter; for example, a spacing of 60mm for a 12mm diameter pipe. A larger spacing at this point will cause uneven cooling of the product, leading to uncontrollable deformation. It will also lengthen the injection molding cycle and increase costs.

[0004] In view of this, it is necessary to improve the existing hot runner cooling structure to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides a novel conformal sealed water tank cooling structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a novel conformal sealing water tank cooling structure, including several hot runner channels disposed in a mold and several cooling water pipes near the bottom hot nozzles of the hot runner channels. The cooling water pipes include a first cooling water pipe and a second cooling water pipe. The first cooling water pipe is staggered with the hot runner channels, meaning the first cooling water pipe can pass directly through the hot runner channels in a straight line without interfering with the heat flow; the second cooling water pipe intersects with the hot runner channels, meaning that when the second cooling water pipe extends in a straight line, it will pass through the location of the hot runner channels and needs to detour. A cooling bypass assembly is provided at the intersection, which connects the second cooling water pipes on both sides of the hot runner. The cooling bypass assembly includes a conformal cooling water tank, a conformal sealing ring, and a vertical connecting pipe. The shape of the conformal cooling water tank matches the shape of the hot runner so that the conformal cooling water tank wraps around the outer side of the outer wall of the hot runner. The conformal sealing ring is fitted on the outer side of the conformal cooling water tank, and its shape is adapted to the shape of the conformal cooling water tank. A vertical connecting pipe is provided below each of the two ends of the conformal cooling water tank, which connects the conformal cooling water tank to the second cooling water pipes on both sides of the hot runner.

[0007] The conformal sealing ring serves two purposes: sealing the mating surfaces and isolating the cooling water pipes from the hot runners. This effectively reduces the safe distance between the cooling water pipes and the hot runners, allowing for an increase in the number of cooling water pipes and a reduction in the spacing between adjacent cooling water pipes.

[0008] Furthermore, the conformal cooling water tank and conformal sealing ring are positioned at the mold mating surface.

[0009] Furthermore, the diameter of the cooling water pipe is 5-15mm, and the spacing H2 between adjacent cooling water pipes is 5 times the diameter of the cooling water pipe.

[0010] Preferably, the diameter of the cooling water pipe is 6mm, 8mm, 10mm, 12mm, or 15mm. For example, when the diameter of the cooling water pipe is 12mm, the spacing H2 is 60mm, which meets the standard spacing requirements.

[0011] Preferably, the diameter D of the hot runner is 55-60 mm.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a novel conformal sealing water tank cooling structure. The design of a conformal cooling water tank combined with a conformal sealing ring solves the problem of uncontrollable deformation caused by uneven cooling due to excessive spacing. The cooling water pipes are arranged according to standard spacing, and a conformal cooling water tank is simply made to bypass the locations of the heat nozzles. The conformal sealing ring uses commonly available sealing rings on the market, without increasing costs. The more heat nozzles there are, the stronger the advantages of this design.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] like Figures 4-9As shown, this utility model discloses a novel conformal sealing water tank cooling structure, comprising several hot runners 1 disposed within a mold and several cooling water pipes 2 near the bottom hot nozzles 3 of the hot runners 1. Each cooling water pipe 2 includes a first cooling water pipe 2a and a second cooling water pipe 2b. The first cooling water pipe 2a is staggered with the hot runners 1, and the second cooling water pipe 2b intersects with the hot runners 1. A cooling bypass assembly is provided at the intersection, connecting the second cooling water pipes 2b on both sides of the hot runners 1. The bypass assembly includes a conformal cooling water tank 4, a conformal sealing ring 5, and a vertical connecting pipe 7. The shape of the conformal cooling water tank 4 matches the shape of the hot runner 1, allowing it to wrap around the outer wall of the hot runner 1. The conformal sealing ring 5 is fitted onto the outer side of the conformal cooling water tank 4, and its shape is adapted to the shape of the conformal cooling water tank 4. A vertical connecting pipe 7 is provided below each of the two ends of the conformal cooling water tank 4, connecting the conformal cooling water tank 4 to the second cooling water pipes 2b on both sides of the hot runner 1. The conformal cooling water tank 4 and the conformal sealing ring 5 are located at the mold mating surface 8. The diameter of the cooling water pipe 2 is 5-15mm, and the spacing H2 between adjacent cooling water pipes 2 is 5 times the diameter of the cooling water pipe 2. Preferably, the diameter of the cooling water pipe 2 is 6mm, 8mm, 10mm, 12mm, or 15mm. For example, when the diameter of the cooling water pipe 2 is 12mm, the spacing H2 is 60mm, which meets the standard spacing requirements. Preferably, the diameter D of the hot runner 1 is 55-60 mm.

[0028] In this embodiment, the use of conformal cooling water tank 4 and conformal sealing ring 5 can bypass the hot runner 1, solving the problem of limited spacing between cooling water pipes 2. This allows for an increase in the number of cooling water pipes 2. In this embodiment, there were originally 4 cooling water pipes 2 in the same area. After the structural optimization of this utility model, the area can be increased to 6 cooling water pipes 2, greatly improving the cooling efficiency.
