Description

Technical Field

[0001] This utility model provides a hot runner cleaning device, belonging to the field of mold technology. Background Technology

[0002] In the field of plastic injection molding, the hot runner system is a crucial component, widely used in the production of various plastic products. The hot runner system mainly consists of a manifold and open-faced hot nozzles. The manifold's function is to evenly distribute the molten plastic injected by the injection molding machine to each hot nozzle; the open-faced hot nozzles are responsible for precisely injecting the molten plastic into the mold cavity. Over long-term use, plastic residue, impurities, and carbon deposits will accumulate in the hot runner. Regular disassembly and cleaning of the hot runner is a key step in ensuring smooth injection molding production.

[0003] Currently, the two most common cleaning methods are soaking cleaning and rinsing cleaning. Soaking cleaning involves placing the hot runner in a specific cleaning solution, which softens and dissolves the dirt. Rinsing cleaning uses high-pressure water or cleaning fluid to impact the inside of the hot runner, quickly removing surface dirt and some residual impurities, resulting in high cleaning efficiency.

[0004] In practice, hot runners are typically cleaned using a combination of two methods: soaking followed by rinsing. Soaking softens and dissolves the dirt before rinsing with the force of the cleaning solution. However, this method is cumbersome. First, the hot runner needs to be removed from the cleaning tank. Then, to ensure its stability, it needs to be secured before the rinsing device is inserted to clean it. This entire process, from soaking to rinsing, is time-consuming and labor-intensive, increases the workload of operators, and reduces the overall efficiency of hot runner cleaning. Therefore, a new hot runner cleaning device is needed to address these issues. Utility Model Content

[0005] The technical problem this invention aims to solve is that the cleaning method of combining soaking and rinsing is rather cumbersome when cleaning hot runners.

[0008] The storage tank containing cleaning fluid is fixedly mounted on a support, and a delivery pipe is output from the storage tank; the plug-in fixing assembly has a rinsing hole, and the delivery pipe is connected to the rinsing hole.

[0009] As an improvement, the lifting assembly includes a first electric telescopic rod, a first lifting plate, and a connecting rod; the first electric telescopic rod is mounted on a bracket, the first lifting plate is fixedly connected to the working end of the first electric telescopic rod, and a connecting rod fixedly connected to the placement plate is fixedly connected below the first lifting plate.

[0010] As an improvement, the insertion and fixing assembly includes a second electric telescopic rod, a second lifting plate, an insertion tube, and a positioning plate; the second electric telescopic rod is disposed below the first lifting plate, the second lifting plate is fixedly connected to the working end of the second electric telescopic rod, the insertion tube is fixedly connected below the second lifting plate, and the insertion tube corresponds to the hot nozzle; the positioning plate is fixedly sleeved on the insertion tube.

[0011] As an improvement, the flushing holes are evenly distributed on the outside of the insertion tube, and the number of insertion tubes is the same as the number of hot nozzles.

[0012] As an improvement, the placement plate is provided with a positioning groove, the diverter plate is located in the positioning groove, and the positioning groove is provided with a guide hole corresponding to the feed hole of the diverter plate.

[0013] As an improvement, the storage box is equipped with a delivery pump corresponding to the delivery pipe on its side wall. The delivery pipe is a flexible hose and is connected to the insertion tube through a second lifting plate.

[0014] The beneficial effects of this utility model are:

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] according to Figure 1-5 As shown: This utility model provides a hot runner cleaning device: including a cleaning cylinder 1, a hot runner 6 located inside the cleaning cylinder 1, a cleaning liquid stored in the cleaning cylinder 1, and a support 2 provided above the cleaning cylinder 1; the hot runner 6 includes a flow divider 16 and a hot nozzle 17, and the hot nozzle 17 is fixedly connected to the flow divider 16.

[0024] The placement plate 11 is located inside the cleaning cylinder 1, and the hot runner 6 is placed on the placement plate 11; the bracket 2 is equipped with a lifting assembly that can drive the placement plate 11 to slide up and down; such as Figure 1 , 2 As shown in Figure 3, the lifting assembly includes a first electric telescopic rod 4, a first lifting plate 3, and a connecting rod 12. The first electric telescopic rod 4 is mounted on the bracket 2, and the first lifting plate 3 is fixedly connected to the working end of the first electric telescopic rod 4. A connecting rod 12, which is fixedly connected to the placement plate 11, is also fixedly connected below the first lifting plate 3. The first electric telescopic rod 4 allows for easy lifting and lowering of the placement plate 11, thus enabling free control of whether the hot runner 6 is inside or outside the cleaning cylinder 1, facilitating combined soaking and rinsing cleaning.

[0025] The lifting assembly contains a plug-in fixing component, and the plug-in fixing component corresponds to the position of the hot nozzle 17; for example Figure 4As shown, the insertion and fixing assembly includes a second electric telescopic rod 7, a second lifting plate 8, an insertion tube 14, and a positioning plate 13. The second electric telescopic rod 7 is located below the first lifting plate 3, enabling the entire insertion and fixing assembly to move according to the movement of the first lifting plate 3. The second lifting plate 8 is fixedly connected to the working end of the second electric telescopic rod 7, and the insertion tube 14 is fixedly connected below the second lifting plate 8, with the insertion tube 14 corresponding to the hot nozzle 17. The diameter of the insertion tube 14 is smaller than the inner diameter of the hot nozzle 17, ensuring that the cleaning fluid can properly soak the inside of the hot nozzle 17 when the insertion tube 14 is inserted into the hot nozzle 17. The positioning plate 13 is fixedly sleeved on the insertion tube 14, and the hot nozzle 17 and the entire hot runner 6 can be quickly fixed using the insertion tube 14 and the positioning plate 13.

[0026] A storage tank 5 containing cleaning fluid is fixedly mounted on a support 2, and a delivery pipe 10 is output from the storage tank 5; a flushing hole 15 is provided on the insertion fixing assembly, and the delivery pipe 10 is connected to the flushing hole 15. The flushing holes 15 are evenly distributed on the outside of the insertion tube 14, which can evenly flush the inside of the hot nozzle 17; and the number of insertion tubes 14 is the same as the number of hot nozzles 17.

[0027] like Figure 5 As shown, a positioning groove 19 is provided in the placement plate 11, and the flow divider 16 is located in the positioning groove 19, which can play a positioning role for the entire hot runner 6, so that the hot nozzle 17 can correspond to the insertion tube 14 after positioning; and a guide hole 18 corresponding to the feed hole of the flow divider 16 is provided in the positioning groove 19. When the hot nozzle 17 is rinsed by the rinsing hole 15, the dirt and impurities rinsed off can flow into the cleaning cylinder 1 through the flow divider 16 and the guide hole 18.

[0028] like Figure 2 As shown, the storage tank 5 is equipped with a delivery pump 9 corresponding to the delivery pipe 10 on its side wall, which can provide power for the flow of cleaning fluid; the delivery pipe 10 is a sufficiently long hose, and the delivery pipe 10 is connected to the insertion pipe 14 through the second lifting plate 8; when the second lifting plate 8 moves under the action of the second electric telescopic rod 7 or the first electric telescopic rod 4, the sufficiently long delivery pipe 10 can ensure the normal connection between the storage tank 5 and the insertion pipe 14.

[0029] The principle of this utility model

[0030] like Figure 3As shown, when using this application, the hot runner 6 is first placed on the placement plate 11, so that the flow divider 16 is located in the positioning groove 19, thereby positioning the hot runner 6, and at this time the insertion tube 14 corresponds to the open hot nozzle 17. The second electric telescopic rod 7 is activated, and the insertion tube 14 is moved downward through the second lifting plate 8, so that the insertion tube 14 is inserted into the hot nozzle 17. At the same time, the positioning plate 13 presses on the end of the hot nozzle 17, which can fix the entire hot runner 6. The first electric telescopic rod 4 is activated, and the first lifting plate 3 and the connecting rod 12 are used to move the placement plate 11 and the hot runner 6 fixed on the placement plate 11 downward into the cleaning tank 1, so that the entire hot runner 6 is immersed in the cleaning tank 1.

[0031] After a period of time, simply activate the first electric telescopic rod 4 to raise the fixed hot runner 6, detaching it from the cleaning cylinder 1. Then, activate the delivery pump 9 to use the cleaning fluid in the storage tank 5 to rinse the inside of the hot nozzle 17. The rinsed wastewater then flows through the diverter plate 16 and the guide hole 18 before finally falling back into the cleaning cylinder 1. The whole process is very convenient. The hot runner 6 can be immersed in the cleaning cylinder 1 in a fixed state first, and after immersion, the hot nozzle 17 can be rinsed directly using the insertion tube 14 that fixes the hot runner 6, greatly improving work efficiency and achieving good cleaning results.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
