Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a mold water-cooling flow channel structure. Background Art

[0002] Molds are tools used to create objects. These tools are composed of various parts, and different molds are made of different parts. They primarily shape objects by changing the physical state of the material being molded. They are often called the "mother of industry."

[0003] At present, when most injection molds are used, it is necessary to first inject the molding melt into the closed mold, and then cool it by injecting cooling water into the cooling cavity opened inside the mold, so that the melt is cooled and formed when demolding. However, most of the current mold cooling cavities are opened inside the mold. The cooling water flows from the inside of the cooling cavity for a long time, and scale will adhere to the inner wall of the cooling cavity. The thermal conductivity of scale is very poor. Thick scale will reduce the thermal conductivity of the cooling cavity. The existing mold cooling cavity is not convenient for cleaning the scale on the inner wall. Therefore, it is necessary to design a mold water-cooling runner structure that can facilitate the cleaning of the cooling cavity to solve the above problems. Utility Model Content

In other words, in some embodiments of the present invention, these physical details are not essential. Furthermore, to simplify the illustrations, some commonly used structures and components are depicted in a simplified schematic manner.

[0024] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0025] In the description of this technology, it should also be noted that, unless otherwise specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this technology based on the specific circumstances.

[0026] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0027] See also Figure 1-5 The utility model includes a lower mold 01 and an upper mold 011. The opposite surfaces of the upper mold 011 and the lower mold 01 are provided with a male mold 031 and a female mold 03. The upper mold 011 and the lower mold 01 are both provided with a cooling assembly. The cooling assembly includes a first butt joint pipe 04, a second butt joint pipe 041, a second through hole 042, a first cooling groove 043 and a second cooling groove 044. The first cooling groove 043 and the second cooling groove 044 are respectively opened in the upper mold 011 and the lower mold 01. A feeding assembly is provided at the top of the upper mold 011. The feeding assembly includes a feeding hole 025, a plug-in column 021, a first through hole 024 and a limiting tube 026. The first through hole 024 runs through the middle of the bottom end of the male mold 031. The male mold 031 and the female mold 03 are docked with the first cooling groove 043 and the second cooling groove 044 through the mounting assembly; the mounting assembly includes a mounting flange 032, a threaded hole 033 and a mounting groove 034. The four corners of the top of the lower mold 01 are fixedly connected to the docking rod 012, and the four corners of the bottom end surface of the upper mold 011 are provided with a docking socket 013.

[0028] See also Figure 4 and Figure 5 In this embodiment, in order to better install and disassemble the male mold 031 and the female mold 03 and the first cooling groove 043 and the second cooling groove 044, the opposing surfaces of the first cooling groove 043 and the second cooling groove 044 are both open, and the installation grooves 034 are both opened at positions close to the edges of the opposing surfaces of the first cooling groove 043 and the second cooling groove 044;

[0029] The edges of the male mold 031 and the female mold 03 are integrally formed with mounting flanges 032 , and threaded holes 033 are opened through the four corners of the mounting flanges 032 . The size of the mounting flanges 032 matches the mounting grooves 034 .

[0030] When the male mold 031 and the female mold 03 need to be installed and docked with the first cooling groove 043 and the second cooling groove 044, first align the mounting flanges 032 of the male mold 031 and the female mold 03 with the mounting groove 034 and insert them, then screw the fixing screws into the threaded holes 033 to fix them.

[0031] See also Figure 1 and Figure 3 It should be noted that, in order to make it easier for the staff to inject the raw materials into the interior of the female mold 03, the feeding assembly also includes a threaded ring 02, a limiting plate 022 and a handle 023. The threaded ring 02 is fixedly connected to the top surface of the upper mold 011 near the edge of the feed hole 025, the limiting plate 022 is fixedly connected to the top of the plug-in column 021, and the handle 023 is fixedly connected to the top of the limiting plate 022. The bottom end surface of the limiting plate 022 is provided with a threaded groove that matches the threaded ring 02.

[0032] One end of the limiting tube 026 is fixedly connected to the inner side of the male mold 031 at a position corresponding to the first through hole 024, and the other end of the limiting tube 026 is movably inserted into the feed hole 025. The feed hole 025 is connected to the inner cavity of the limiting tube 026 and the first through hole 024;

[0033] The diameter of the plug-in column 021 matches the inner diameter of the limiting tube 026 and the first through hole 024 . After the plug-in column 021 is inserted, the bottom end surface is flush with the bottom end surface of the male mold 031 .

[0034] When it is necessary to inject material, first align the docking rod 012 with the docking hole 013 and insert it, so that the upper mold 011 and the lower mold 01 are closed, and then the raw material is injected from the feed hole 025. The raw material flows from the feed hole 025 into the limiting tube 026 and then flows into the inside of the female mold 03 from the first through hole 024. After the injection is completed, grab the handle 023 and insert the plug-in column 021 into the feed hole 025, the limiting tube 026 and the first through hole 024. Then grab the handle 023 and rotate the plug-in column 021 so that the threaded groove at the bottom end of the limiting disk 022 is threadedly connected with the threaded ring 02, thereby fixing the plug-in column 021. After the threaded connection between the limiting disk 022 and the threaded ring 02 is completed, the bottom end face of the plug-in column 021 is flush with the bottom end face of the male mold 031, so that when the raw material is extruded by the male mold 031, no depression will appear on the formed raw material.

[0037] There are two groups of first cooling slots 043 , with two first cooling slots in each group. The first cooling slots 043 in each group are connected via the second through holes 042 .

[0038] After the raw material is injected into the inside of the concave mold 03, the cooling water source is connected to the first butt joint 04 and the second butt joint 041 on the front of the upper mold 011 and the lower mold 01 from the outside, and the cooling water is injected into the first cooling groove 043 and the second cooling groove 044, and finally discharged from the first butt joint 04 and the second butt joint 041 on the back of the upper mold 011 and the lower mold 01, forming a water circulation.
