Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection molding component technology, specifically an open-type hot runner injection molding component. Background Technology
[0002] In modern injection molding processes, the application of hot runner technology has become one of the key means to improve production efficiency and ensure the quality of injection molded parts. The hot runner system can keep the plastic in a molten state in the runner by setting heaters on the hot nozzles, thereby avoiding the waste caused by the cooling and solidification of plastic in the traditional cold runner system, and greatly improving the utilization rate of raw materials and production efficiency.
[0003] In the injection molding process, in order to achieve efficient and stable production, it is necessary to ensure that the molten plastic can be smoothly and evenly distributed into each mold cavity. Usually, the hot nozzle is designed with an open mouth, so that the molten plastic can flow directly from the front end of the nozzle and be reasonably distributed into multiple mold cavities by the manifold. In order to prevent workers from accidentally touching the hot nozzle and getting burned, a protective plate is usually installed on the hot nozzle to provide effective protection for the workers.
[0004] However, when installing protective plates on existing hot nozzles, in order to ensure that the protective plates do not wobble during use, they are usually fixed to the nozzle by welding. If impurities get on the protective plates, it is difficult for workers to remove them for cleaning. This may result in incomplete cleaning of the protective plates, and impurities may enter the hot nozzle, affecting the normal operation of the hot nozzle. Utility Model Content
[0005] The purpose of this invention is to provide an open-type hot runner injection molding component to solve the problem of difficult-to-clean impurities in the protective plate mentioned in the background art.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0025] like Figure 1 - Figure 5As shown, this application provides an open-type hot runner injection molding component, including: an injection molding machine body 1, an injection mold 2 disposed on the injection molding machine body 1, a fixed template 4 disposed on the injection mold 2, a protective plate 6 disposed on the fixed template 4, an open-type hot nozzle body 15 disposed on the injection molding machine body 1, a heater 3 disposed on the open-type hot nozzle body 15, and further including: a removable assembly disposed on the open-type hot nozzle body 15, the removable assembly including a mounting plate 5 and a fixing groove 11, the mounting plate 5 being disposed on the open-type hot nozzle body 15, a connecting plate 8 disposed on the mounting plate 5, a fixing block 10 disposed on the connecting plate 8, a fixing rod 17 disposed on the mounting plate 5, and the fixing groove 11 being disposed on the protective plate 6, the removable assembly being used for quick removal of the protective plate 6.
[0026] Specifically, such as Figure 5 As shown, the easy-to-disassemble component includes connecting grooves 23 symmetrically arranged on the mounting plate 5. A rotating shaft 20 is rotatably arranged in the connecting grooves 23. A connecting plate 8 is fixedly arranged on the outside of the rotating shaft 20. A torsion spring 22 is arranged between the connecting plate 8 and the connecting grooves 23. The torsion spring 22 is located on the outside of the rotating shaft 20. When the protective plate 6 is disassembled, the elastic force of the torsion spring 22 can drive the connecting plate 8 to rotate 90 degrees, which facilitates the quick disassembly of the protective plate 6.
[0027] Specifically, such as Figure 3 As shown, the mounting plate 5 is provided with a limiting groove 16, and the telescopic plate 7 is provided with a limiting plate 12 corresponding to the limiting groove 16. The limiting plate 12 matches the limiting groove 16. Through the cooperation of the limiting groove 16 and the limiting plate 12, the pre-positioning of the protective plate 6 during installation can be achieved.
[0028] Specifically, such as Figure 3 As shown, the fixing groove 11 is set on the limiting plate 12. The fixing groove 11 matches the fixing block 10. The fixing plate 6 is fixed by the cooperation of the fixing block 10 and the fixing groove 11.
[0029] Specifically, such as Figure 5 As shown, two sets of storage slots 19 are symmetrically arranged on the mounting plate 5. The fixing rod 17 is movably arranged in the storage slot 19 and passes through the storage slot 19. The fixing rod 17 can be used to fix the connecting plate 8.
[0030] Specifically, such as Figure 5 A connecting block 9 is fixedly connected to the side of the fixed rod 17 away from the limiting groove 16. A spring 18 is provided between the connecting block 9 and the storage groove 19. The spring 18 is located on the outside of the fixed rod 17. A fixing hole 21 is provided on the connecting plate 8 corresponding to the fixed rod 17. Through the elastic force of the spring 18, the fixed rod 17 can be driven to be firmly locked in the fixing hole 21.
[0031] The protective plate 6 is provided with a telescopic component, which includes a telescopic plate 7 provided on the protective plate 6 and an elastic element 14 provided on the protective plate 6. The telescopic component is used for the expansion of the protective plate 6.
[0032] Specifically, such as Figure 4 As shown, the telescopic assembly also includes a sliding groove 24 on the telescopic plate 7 corresponding to the protective plate 6. The protective plate 6 is movably disposed in the sliding groove 24. The sliding groove 24 can prevent the protective plate 6 from rotating.
[0033] Specifically, such as Figure 4 As shown, a telescopic rod 13 is provided between the protective plate 6 and the limiting plate 12. An elastic element 14 is provided on the outside of the telescopic rod 13 and between the limiting plate 12 and the protective plate 6. Through the elastic force of the telescopic rod 13, the protective plate 6 can be driven to maintain the protection of the open-type hot nozzle body 15.
[0034] In this embodiment: by pulling the connecting block 9, the spring 18 can be stretched, which can cause the fixing rod 17 to disengage from the fixing hole 21. At this time, the elastic force of the torsion spring 22 can cause the connecting plate 8 to rotate 90 degrees, thereby causing the fixing block 10 to disengage from the fixing groove 11. This makes it easier for the staff to remove the protective plate 6 and thoroughly clean it. Through the cooperation of the protective plate 6 and the elastic element 14, the protective plate 6 can always keep protecting the open-type hot nozzle body 15, thus achieving comprehensive protection for the open-type hot nozzle body 15. At the same time, when the open-type hot nozzle body 15 enters the injection port, the blocking of the fixed template 4 can prevent the normal function of the open-type hot nozzle body 15 from being affected.
[0035] Specifically, when a thorough cleaning of the protective plate 6 is required, the worker pulls the connecting block 9, causing the fixing rod 17 to disengage from the fixing hole 21. At this time, the spring force of the torsion spring 22 drives the connecting plate 8 to rotate, thereby causing the fixing block 10 to disengage from the fixing groove 11. The worker then pulls the protective plate 6, causing the limiting plate 12 to disengage from the limiting groove 16. This facilitates quick and thorough cleaning of the protective plate 6, preventing impurities on the protective plate 6 from affecting the normal operation of the open-type hot nozzle body 15. When the nozzle body 15 is installed, the operator controls the limiting plate 12 to be inserted into the limiting groove 16, and then controls the connecting plate 8 to rotate, thereby driving the fixing block 10 to be inserted into the fixing groove 11. Through the elastic force of the spring 18, the fixing rod 17 can be firmly locked in the fixing hole 21, thereby fixing the protective plate 6. Through the cooperation of the telescopic plate 7 and the elastic element 14, when the open-type hot nozzle body 15 is inserted into the injection port on the fixed template 4, the protective plate 6 can be driven to move in the opposite direction of the fixed template 4, thereby effectively preventing the protective plate 6 from affecting the normal operation of the open-type hot nozzle body 15.
