Description

Technical Field

[0001] This utility model belongs to the field of shower head production technology, and in particular relates to a hot runner inverted mold for shower head molding. Background Technology

[0002] Shower heads, also known as shower heads, use shower head covers as the water outlet covers. They are generally made of plastic and need to maintain a high-quality appearance. Therefore, hot runner inverted molds are usually designed for production. Because hot runner inverted molds have high temperatures and the shower head covers have a disc structure, the existing traditional straight-in-straight-out water flow structure is difficult to cool the injection molded products quickly, resulting in long product molding cycles and the inability to reduce production costs.

[0003] To address the aforementioned issues, patent number CN202421112714.7 discloses a technical solution for mold cooling. This solution involves setting an annular cooling cavity within the mold, utilizing the flow of liquid within the cavity to remove heat generated during production. However, in actual use, due to the prolonged flow of liquid within the mold cavity and the resulting heat, scale may form in the cavity and adhere to its inner wall. Since the cavity is located within the mold, manual cleaning is difficult and time-consuming. Over time, this reduces the cooling efficiency of the equipment, thus impacting production. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a hot runner inverted mold for shower head cover forming, which solves the problem that the existing equipment cannot clean the cooling cavity in a timely and convenient manner during use, resulting in a decrease in the heat conduction efficiency of the inner wall of the cooling cavity.

[0005] This utility model is implemented as follows: a hot runner inverted mold for forming a shower head cover includes a lower mold and an upper mold. The upper mold is fixedly provided with a positioning rod for positioning the lower mold and the upper mold during mold closing. The lower mold has a cooling groove for cooling. The model also includes:

[0006] A cleaning component, installed inside the cooling tank, is used for cleaning the cooling tank. It includes a filter plate that is slidably installed inside the cooling tank, and scrapers are fixedly installed on both the upper and lower sides of the filter plate.

[0009] The sealing assembly includes a push plate fixedly mounted on a wire rope and a sealing block movably mounted inside the slag discharge pipe, and the sealing block is opened by the push plate.

[0010] The drive assembly, located inside the lower mold, is used to drive the movement of the filter plate and the winding of the wire rope. The drive assembly is driven by teeth located inside the positioning rod.

[0011] As a preferred embodiment of this invention, the cleaning assembly further includes a track formed on the side of the cooling tank, and a ball bearing is installed on each side of the filter plate, the ball bearing being rolled within the track.

[0012] As a preferred embodiment of the present invention, the movable component further includes a first winding reel and a second winding reel rotatably disposed within the lower mold, wherein the winding directions of the first winding reel and the second winding reel are opposite, and the two ends of the wire rope are respectively wound around the first winding reel and the second winding reel, wherein the first winding reel and the second winding reel are respectively disposed at both ends of the cooling tank, and a torsion spring for resetting is installed on the lower side of the first winding reel.

[0030] An L-shaped slag discharge pipe 19 for impurity discharge is provided in the lower mold 1, and the slag discharge pipe 19 is sealed by a sealing component provided in the lower mold 1.

[0031] The sealing assembly includes a push plate 11 fixedly mounted on the wire rope 8 and a sealing block 16 movably mounted in the slag discharge pipe 19, and the sealing block 16 is opened by the push plate 11.

[0032] The drive assembly is located inside the lower mold 1 and is used to drive the movement of the filter plate 5 and the winding of the wire rope 8. The drive assembly is driven by the teeth 15 located inside the positioning rod 3.

[0033] As a preferred embodiment of this utility model, the cleaning component also includes a track opened on the side of the cooling tank 4, and a rolling ball 7 is installed on each side of the filter plate 5. The rolling ball 7 is rolled in the track to limit the filter plate 5, ensure its running trajectory, and prevent it from deviating during operation.

[0034] As a preferred embodiment of this utility model, the moving component further includes a first winding reel 9 and a second winding reel 12 rotatably disposed within the lower mold 1, with the winding directions of the first winding reel 9 and the second winding reel 12 being opposite. The two ends of the wire rope 8 are respectively wound around the first winding reel 9 and the second winding reel 12, wherein the first winding reel 9 and the second winding reel 12 are respectively disposed at both ends of the cooling tank 4. A torsion spring 10 for resetting is installed on the lower side of the first winding reel 9 to facilitate the winding of the wire rope 8, thereby effectively pulling the filter plate 5 to move, and thus achieving the cleaning of the cooling tank 4.

[0035] As a preferred embodiment of this utility model, the sealing assembly further includes a spring 17 fixedly disposed within the slag discharge pipe 19, and a sealing block 16 movably slidingly disposed within a fixing ring 18 via a spring 17. The fixing ring 18 is movably fixedly disposed on the slag discharge pipe 19, and a steel wire rope 8 movably passes through the sealing block 16 and the fixing ring 18 to facilitate the discharge of impurities during cleaning and prevent the accumulation of impurities.

[0036] As a preferred embodiment of this utility model, the drive assembly includes a gearbox 13 installed in the lower mold 1, and the output end of the gearbox 13 is connected to the second take-up reel 12 for transmission. The inlet and outlet ends of the gearbox 13 are equipped with drive gears 14 that mesh with the teeth 15, which realizes cleaning when the equipment closes the mold and merging when the mold opens, thereby further ensuring the cooling effect of the cooling tank 4.

[0037] The working principle of this utility model:

[0038] refer to Figure 4 In the initial state of the equipment, the wire rope 8 is located in the cooling tank 4, and the push plate 11 and the spring 17 are located at both ends of the cooling tank 4 respectively. At the same time, the filter plate 5 is located behind the push plate 11 and is blocked by the push plate 11. The blocking block 16 is located behind the spring 17. At the same time, the two ends of the wire rope 8 are wound by the first winding reel 9 and the second winding reel 12 inside the lower mold 1. During operation;

[0039] refer to Figure 1 When the upper mold 2 descends, the lower mold 1 and the upper mold 2 close together. The positioning rod 3 installed on the upper mold 2 is inserted into the lower mold 1, and as the positioning rod 3 descends, the teeth 15 inside the positioning rod 3 are driven. Figure 4 The drive gear 14 rotates, reference Figure 5 When the drive gear 14 rotates forward, it drives the gearbox 13 to work. The output end of the gearbox 13 drives the second take-up reel 12 to rotate and wind up the wire rope 8. At the same time, the first take-up reel 9 unwinds the wire rope. Since the two ends of the torsion spring 10 are fixed to the lower mold 1 and the first take-up reel 9 respectively, the torsion spring 10 is compressed when the second take-up reel 12 rotates forward. As the second take-up reel 12 winds up the wire rope 8, the push plate 11 and the filter plate 5 installed on the wire rope 8 gradually move under the cooperation of the rolling ball 7 and the track groove in the cooling tank 4, causing the filter plate 5 to move towards the second take-up reel 12. As the reel 12 moves to one side, the scraper 6 installed on the filter plate 5 cleans the inner wall of the cooling tank 4. At the same time, the filter plate 5 filters the impurities after cleaning, pushing the impurities to one side of the second reel 12. When the push plate 11 moves to the position of the fixed ring 18, the push plate 11 enters the fixed ring 18. At the same time, the push plate 11 is pulled by the wire rope 8, causing the push plate 11 to push the sealing block 16 away from the fixed ring 18. At the same time, the spring 17 is stretched. At this time, the slag discharge pipe 19 is in the open state, and the impurities are discharged through the slag discharge pipe 19. The discharged liquid is filtered and circulated by the external filtration and circulation equipment.

[0040] When the lower mold 1 and upper mold 2 of the equipment open, the tooth 15 drives the drive gear 14 to rotate in the opposite direction. Figure 5 The torsion spring 10 drives the first winding reel 9 to rotate in the opposite direction, so that the first winding reel 9 winds up the wire rope 8, while the second winding reel 12 is in the unwinding state. When the push plate 11 moves away from the fixing ring 18, the spring 17 drives the sealing block 16 to reset. At this time, the sealing block 16 can effectively block the slag discharge pipe 19 again, preventing the discharge of liquid, and thus repeating the work.

[0041] This invention utilizes the periodic winding of the second winding reel 12 and the first winding reel 9 in the equipment to effectively drive the wire rope 8 to move within the cooling tank 4. As the wire rope 8 moves within the cooling tank 4, the filter plate 5 installed on the wire rope 8 can also move effectively within the cooling tank 4, thereby effectively cleaning the cooling tank 4. Simultaneously, the cleaned residue can be effectively discharged through the slag discharge pipe 19, further preventing the inner wall of the cooling tank 4 from containing a large amount of scale, which would affect the cooling effect of the cooling tank 4. Furthermore, through the mold opening and closing of the equipment, the equipment can achieve automatic cleaning during operation, further improving the practicality and ease of use of the equipment.
