Description

Technical Field

[0001] This utility model relates to the field of injection molds, and in particular to a high-precision injection mold core. Background Technology

[0002] With the development of high-precision injection mold cores, more and more injection molds are being used in toy factories, plastic products and special processes. In these applications, the demolding and installation / disassembly of injection mold cores have always been a problem. In order to achieve the effects of cooling and quick installation of water pipes, an injection mold that can further cool down and quickly install and remove water pipes was designed.

[0003] Existing high-precision injection molds generally use water-circulating cooling devices, which cannot accurately reach the required temperature, leading to difficulties in demolding and requiring manual repairs. This consumes a lot of time in repairing and fixing the device, seriously affecting production efficiency.

[0004] Existing high-precision injection molds have a prominent problem: the large number of water pipes during mold installation or disassembly wastes a lot of time, affecting maintenance and work efficiency, resulting in losses in both time and mechanical costs. Therefore, there is an urgent need for an injection mold that can further cool down and quickly disassemble the water pipes. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-precision injection mold core, which aims to improve the problems of slow product molding when the temperature is too high and the time spent on manual maintenance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-precision injection mold core, including an upper mold base, a punch one fixedly connected to the bottom of the upper mold base, a punch two fixedly connected to the bottom of the punch one, a fixing rod fixedly connected to the bottom of the punch two, a lower mold base fixedly connected to the bottom of the fixing rod, and a heat dissipation component fixedly connected to the top of the upper mold base;

[0012] As a further description of the above technical solution:

[0013] The top of the ejector plate is fixedly connected to a guide post, and a water-cooling assembly is provided inside the punch.

[0014] As a further description of the above technical solution:

[0015] The water-cooling assembly includes a housing, and an internal hexagon bolt is fixedly connected to the top of the housing. The internal hexagon bolt has a connection port inside.

[0016] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, heat is first transferred to the fan through the heat pipe of the aluminum heat sink plate.

[0024] 2. In this utility model, the water pipe is quickly fixed in the internal structure by locking the barb of the locking spring.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 The present invention provides an embodiment of a high-precision injection mold core, comprising an upper mold base 1, which is used to connect the mechanical structure and support a first punch 2. The first punch 2 is fixedly connected to the bottom of the upper mold base 1, and a mold core is fixed in the first punch 2 for injection molding of the product. The second punch 3 is fixedly connected to the bottom of the first punch 2, and the second punch 3 has a cavity that cooperates with the mold core to injection mold the product. A fixing rod 4 is fixedly connected to the bottom of the second punch 3, which connects the second punch 3 and the lower mold base 6 together, providing space for the guide post 5. The lower mold base 6 is fixedly connected to the bottom of the fixing rod 4, and a heat dissipation component is fixed to the top of the upper mold base 1.

[0034] The heat dissipation assembly includes an aluminum heat sink 17, which absorbs the heat generated by the upper mold base 1. The aluminum heat sink 17 is fixedly connected to the top of the upper mold base 1, and a heat pipe 18 is fixedly connected to the top of the aluminum heat sink 17. The heat pipe 18 absorbs and transfers the heat from the aluminum heat sink 17. An aluminum heat-conducting sheet 19 is fixedly connected to one side of the heat pipe 18, and a frame 20 is fixedly connected to one side of the heat pipe 18. The frame 20 is mounted on the heat pipe 18, and a chassis 21 is fixedly connected inside the frame 20. A fan 22 is fixedly connected to one side of the chassis 21, and the fan 22 cools the absorbed heat.

[0035] Reference Figures 1-5 A fixed support column 24 is fixedly connected to one side of the chassis 21. The fixed support column 24 connects the chassis 21 and the fan 22. The fan 22 is fixedly connected to one side of the fixed support column 24. A screw 23 is threadedly connected to one side of the frame 20. The screw 23 is fixed to the heat pipe 18 through the frame 20. A handle 7 is fixedly connected to one side of the upper mold base 1. The mold is lifted by the handle 7 for disassembly and hoisting. An ejector plate 8 is fixedly connected to the top of the lower mold base 6. The ejector plate 8 demolds the injection molded material. A guide post 5 is fixedly connected to the top of the ejector plate 8. A water-cooling component is opened inside the punch 2. The component includes a housing 11, with an internal hex bolt 10 fixedly connected to the top of the housing 11. The internal hex bolt 10 has a connection port 9 inside, which is aligned with the water cooling interface. A sealing ring 13 is fixedly connected inside the housing 11 to ensure stable water cooling flow. A washer 14 is fixedly connected inside the housing 11. A locking spring 15 is fixedly connected inside the housing 11. By pushing the unlocking push rod 12, the locking spring 15 is opened, thereby locking it to the outer wall of the water pipe. A retainer 16 is fixedly connected to the bottom of the housing 11, and the unlocking push rod 12 is fixedly connected to the bottom of the retainer 16.

[0036] Working principle: When using this high-precision injection mold core, heat is first absorbed by the aluminum heat sink 17 that contacts the upper mold base 1. The heat sink 17 then transfers the heat to the heat pipe 18, which in turn transfers the heat to the aluminum heat-conducting sheet 19. The heat from the aluminum heat-conducting sheet 19 is then cooled by the fan 22 inside the frame 20 mounted on the heat pipe 18. The high heat generated by the upper mold base 1 is stabilized at a suitable discharge temperature through its own water cooling and air cooling, reducing the difficulty of demolding under high temperature conditions.

[0037] When using this high-precision injection mold core, the entire structure is fixed in the water cooling port of the mold through the connection port 9. The structure is further fixed with the hexagon socket bolts 10. The water pipe enters from the unlocking push rod 12, which pushes out and deforms the inner wall of the locking spring 15. The angle at which the locking spring 15 is raised will form a barb locking structure, thus playing a fixing role. The sealing ring 13 can ensure that the water pipe entering it will not leak air or water. When it is necessary to pull it out, just press the unlocking push rod 12. The structure inside the unlocking push rod 12 will open the spring, thus enabling quick unlocking.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
