Description

Technical Field

[0001] This utility model relates to the field of connectors, and more specifically, to a mold for manufacturing connector accessories. Background Technology

[0002] Connector component manufacturing molds are meticulously designed and precision-machined to efficiently produce high-quality connector components. These components play a crucial role in electronic devices, ensuring reliable connections between various parts. The mold design takes into account factors such as material flowability and cooling rate to ensure the precision and consistency of the final product. By using these advanced molds, manufacturers can significantly improve production efficiency, reduce costs, and ensure high performance and reliability of their products.

[0003] Utility model patent CN209224419U discloses a mold for manufacturing connector accessories, comprising: a mold base, a sprue bushing on the mold base, a front mold core and a rear mold core inside the mold base, the front and rear mold cores being arranged opposite to each other and communicating with the sprue bushing, a flow divider cone being provided at the connection between the front and rear mold cores and the sprue bushing, and a cooling pipe being provided on the mold base outside the front and rear mold cores. This utility model can improve the uniformity of the accessories and, moreover, can limit the errors of various moving parts of the mold, thereby improving the machining accuracy of the accessories.

[0004] In the aforementioned application, through the cooperation of the mold base and the sprue bushing assembly, the cooling pipe is only located on the outside of the mold base and does not penetrate into the front and rear mold cores. As the high-temperature area that directly contacts the plastic part, the cooling channel of the mold core should be as close as possible to the cavity surface. The existing structure causes the heat inside the mold core to be unable to be dissipated in time. Therefore, we propose a mold for manufacturing connector accessories. Utility Model Content

[0005] This utility model proposes a mold for manufacturing connector accessories.

[0006] The technical solution of this utility model is as follows: A mold for manufacturing connector accessories includes: a base, a lower mold platform fixedly connected to the top of the base, a support column fixedly connected to the top of the base, a top support platform fixedly connected to the top of the support column, and a water-cooling device provided inside the lower mold platform for circulating cooling of the lower mold platform. The water-cooled cooling device includes a base, the side of which is fixedly connected to the side of the lower mold platform, a motor is fixedly connected to the side of the base, a filter screen is fixedly connected to the inner wall of the lower mold platform, a water inlet valve passes through the side of the filter screen, an impeller shaft is fixedly connected to the output shaft of the motor, blades are fixedly connected to the circumferential surface of the impeller shaft, a cooling pipe passes through the inner wall of the lower mold platform, and a fixed seat is rotatably connected to the end of the impeller shaft away from the motor.

[0007] The fixed base is fixedly connected to the side of the lower mold table, and a drive gear is fixedly connected to the end of the impeller shaft near the fixed base. The fixed base provides stable support for the impeller shaft, ensuring its stability during rotation and reducing the impact of shaking on the cooling system. The drive gear provides a basis for subsequent power transmission, facilitating the linkage of multiple components.

[0008] Several cooling pipes are arranged symmetrically along the vertical central axis of the lower mold platform, and a hydraulic assembly is bolted to the top of the top support platform. The symmetrical arrangement of cooling pipes along the vertical central axis ensures more uniform cooling across the lower mold platform, preventing excessive localized temperature differences that could lead to defects in the molded parts. The hydraulic assembly provides stable power to the upper mold platform.

[0009] A tank is fixedly connected to the side of the lower mold platform, and a filter element is fixedly connected to the inner wall of the tank. The tank and the filter element can filter the cooling circulating water, remove impurities from the water, prevent impurities from clogging the cooling pipes and affecting the cooling effect, extend the service life of the water cooling device, and reduce equipment maintenance costs.

[0010] The tank is equipped with a filter element anti-clogging device, which includes a positioning plate. The bottom of the positioning plate is fixedly connected to the top of the base. A rotating shaft is rotatably connected through the side of the positioning plate. A driven gear is fixedly connected to the end of the rotating shaft near the positioning plate. A stabilizing seat is fixedly connected to the side of the base. The rotating shaft is rotatably connected through the side of the stabilizing seat. A pulley is fixedly connected to the end of the rotating shaft near the stabilizing seat. A belt is provided on the circumferential surface of the pulley. A rotating disk is rotatably connected through the side of the tank. A scraper is fixedly connected to the circumferential surface of the rotating disk. A second pulley is fixedly connected to one end of the rotating disk.

[0011] The driving gear meshes with the driven gear for transmission, and pulley one is connected to the circumference of pulley two via a belt drive. Multiple transmission sets achieve power linkage between the water-cooling device and the filter element anti-clogging device, eliminating the need for an additional power source, saving equipment energy consumption, improving energy utilization, and simplifying the equipment structure.

[0012] The circumferential surface of the filter element lies on the displacement trajectory of the scraper. Two scrapers are arranged circumferentially on the circumferential surface of the rotating disk. The scrapers' position on the displacement trajectory of the filter element's circumferential surface allows for comprehensive and uniform cleaning of impurities, improving anti-clogging performance and ensuring the filter element maintains consistently good filtration performance.

[0013] The bottom of the hydraulic assembly is slidably connected to an upper mold platform, and the bottom of the upper mold platform is fixedly connected to a forming tool. The hydraulic assembly drives the upper mold platform to slide, ensuring that the upper mold platform moves smoothly and accurately. Together with the forming tool at the bottom, it can make the connector accessories molded with uniform specifications, thereby improving the product qualification rate and consistency.

[0014] The working principle and beneficial effects of this utility model are as follows: 1. This utility model water-cooled cooling device achieves cooling of the lower mold platform through liquid circulation. After the motor starts, its output shaft drives the impeller shaft and blades to rotate, generating power to drive the coolant to circulate in the system. Through the circulation of coolant, the heat of the lower mold platform can be quickly removed, effectively controlling the mold temperature and avoiding molding defects such as deformation and cracking of connector parts due to excessive temperature. Moreover, the circulation cooling design avoids the waste of coolant. Combined with the motor-driven blades, it enhances the fluidity of the liquid, improves heat dissipation efficiency, and reduces energy consumption.

[0015] 2. The filter element anti-clogging device of this utility model achieves automatic cleaning of the filter element through power linkage, and then drives two scrapers fixed on the circumferential surface of the rotating disk to make circumferential motion. Since the displacement trajectory of the scrapers covers the circumferential surface of the filter element, it can continuously scrape off the impurities attached to the surface of the filter element, preventing the accumulation of impurities and clogging of the filter element. The scrapers continuously clean the impurities on the surface of the filter element, avoiding the filter element's filtration capacity from decreasing due to clogging, ensuring that impurities in the cooling circulating water are effectively intercepted, and preventing the cooling pipe from clogging.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1 like Figures 1-4 As shown, this embodiment proposes a mold for manufacturing connector accessories, including: a base 1, a lower mold platform 11 fixedly connected to the top of the base 1, a support column 2 fixedly connected to the top of the base 1, a top support platform 3 fixedly connected to the top of the support column 2, and a water cooling device 5 provided inside the lower mold platform 11 for circulating cooling of the lower mold platform 11. The water-cooled cooling device 5 includes a base 51, the side of which is fixedly connected to the side of the lower mold platform 11. A motor 52 is fixedly connected to the side of the base 51. A filter screen 53 is fixedly connected to the inner wall of the lower mold platform 11. A water inlet valve 54 passes through the side of the filter screen 53. An impeller shaft 55 is fixedly connected to the output shaft of the motor 52. Blades 56 are fixedly connected to the circumferential surface of the impeller shaft 55. A cooling pipe 57 passes through the inner wall of the lower mold platform 11. A fixed seat 58 is rotatably connected to the end of the impeller shaft 55 away from the motor 52.

[0022] The side of the fixed base 58 is fixedly connected to the side of the lower mold table 11, and the end of the impeller shaft 55 near the fixed base 58 is fixedly connected to the drive gear 59. The fixed base 58 provides stable support for the impeller shaft 55, ensuring the stability of the impeller shaft 55 during rotation and reducing the impact of shaking on the cooling system. The drive gear 59 provides a basis for subsequent power transmission, facilitating the linkage of multiple components.

[0023] Several cooling pipes 57 are arranged symmetrically along the vertical central axis of the lower mold platform 11, and a hydraulic assembly 4 is bolted to the top of the top support platform 3. The symmetrical arrangement of cooling pipes 57 along the vertical central axis ensures more uniform cooling across the lower mold platform 11, preventing excessive local temperature differences that could lead to defects in the molding of the parts. The hydraulic assembly 4 provides stable power to the upper mold platform 9.

[0024] A tank 12 is fixedly connected to the side of the lower mold platform 11, and a filter element 7 is fixedly connected to the inner wall of the tank 12. The tank 12, together with the filter element 7, can filter the cooling circulating water, remove impurities from the water, prevent impurities from clogging the cooling pipe 57 and affecting the cooling effect, extend the service life of the water cooling device 5, and reduce equipment maintenance costs.

[0025] In this embodiment, the working principle of the water-cooled cooling device 5 is to achieve efficient cooling through liquid circulation and heat exchange. The specific process is as follows: After the motor 52 starts, its output shaft drives the impeller shaft 55 to rotate at high speed. The blades 56 fixed on the circumferential surface of the impeller shaft 55 rotate accordingly, generating continuous fluid power in the cavity formed by the base 51 and the lower mold platform 11, which pushes the coolant to form a circulating flow. The coolant first enters the system through the water inlet valve 54. When it flows through the filter screen 53, impurities are intercepted to prevent them from entering the subsequent pipeline and causing blockage. Subsequently, the filtered coolant is diverted to several cooling pipes 57 symmetrically distributed along the vertical central axis of the lower mold platform 11. The cooling pipes 57 are tightly attached to the inner wall of the lower mold platform 11, absorbing a large amount of heat generated by the mold during the molding of the connector parts through heat conduction, so that the temperature of the lower mold platform 11 drops rapidly. After absorbing heat, the coolant continues to flow along the pipeline, and after heat dissipation, it re-enters the circulation. The end of the impeller shaft 55 away from the motor 52 is fixed to the side of the lower mold platform 11 by the fixing seat 58, which effectively reduces the shaking during high-speed rotation. The circulating coolant can quickly remove the heat from the lower mold stage 11, effectively controlling the mold temperature and preventing molding defects such as deformation and cracking of connector parts due to excessive temperature. This ensures the stable operation of the entire circulation system. The circulating cooling design avoids the waste of coolant. Combined with the blades 56 driven by the motor 52, it enhances the fluidity of the liquid, improves heat dissipation efficiency, and reduces energy consumption.

[0026] Example 2 like Figures 1-4As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that the tank body 12 is provided with a filter element anti-clogging device 6. The filter element anti-clogging device 6 includes a positioning plate 61. The bottom of the positioning plate 61 is fixedly connected to the top of the base 1. A rotating shaft 62 is rotatably connected through the side of the positioning plate 61. A driven gear 63 is fixedly connected to one end of the rotating shaft 62 near the positioning plate 61. A stabilizing seat 64 is fixedly connected to the side of the base 1. The rotating shaft 62 is rotatably connected through the side of the stabilizing seat 64. A pulley 65 is fixedly connected to one end of the rotating shaft 62 near the stabilizing seat 64. A belt 66 is provided on the circumferential surface of the pulley 65. A rotating disk 67 is rotatably connected through the side of the tank body 12. A scraper 69 is fixedly connected to the circumferential surface of the rotating disk 67. A pulley 68 is fixedly connected to one end of the rotating disk 67.

[0027] The driving gear 59 meshes with the driven gear 63 for transmission, and pulley 65 is connected to the circumference of pulley 68 via belt 66. Multiple transmissions enable the power linkage between the water-cooling device 5 and the filter element anti-clogging device 6, eliminating the need for an additional power source, saving equipment energy, improving energy efficiency, and simplifying the equipment structure.

[0028] The circumferential surface of filter element 7 is located on the displacement trajectory of scraper 69. There are two scrapers 69, which are arranged in a circumferential array on the circumferential surface of rotating disk 67. The scrapers 69 are located on the displacement trajectory of the circumferential surface of filter element 7, which can thoroughly and evenly clean impurities on the surface of filter element 7, improve the anti-clogging effect, and ensure that filter element 7 always maintains good filtration performance.

[0029] The bottom of the hydraulic assembly 4 is slidably connected to an upper mold platform 9, and the bottom of the upper mold platform 9 is fixedly connected to a forming fixture 10. The hydraulic assembly 4 drives the upper mold platform 9 to slide, ensuring that the upper mold platform 9 moves smoothly and accurately. Together with the forming fixture 10 at the bottom, it can make the connector accessories molded in a uniform specification, improving the product qualification rate and consistency.

[0030] In this embodiment, the working principle of the filter element anti-clogging device 6 is linked with the water cooling device 5: when the motor 52 drives the impeller shaft 55 to rotate, the drive gear 59 at the end of the impeller shaft 55 rotates synchronously, and the driven gear 63 meshing with the drive gear 59 rotates accordingly, thereby driving the rotating shaft 62 that passes through the positioning plate 61 and the stabilizing seat 64 to rotate. The pulley 65 at one end of the rotating shaft 62 transmits power to the pulley 68 on the side of the tank 12 through the belt 66, causing the rotating disk 67 connected to the pulley 68 to rotate, and the two scrapers 69 fixed on the circumference of the rotating disk 67 to move in a circular motion with it. Because the displacement trajectory of the scraper 69 covers the circumferential surface of the filter element 7, it can continuously scrape off the impurities attached to the surface of the filter element 7 during rotation, preventing the accumulation of impurities and clogging of the filter element 7. This ensures that the coolant in the tank 12 remains clean after filtration, and guarantees the smooth circulation of the water-cooled cooling device 5. The scraper 69 continuously cleans the impurities on the surface of the filter element 7, preventing the filter element 7 from becoming clogged and reducing its filtration capacity. It also ensures that impurities in the cooling circulating water are effectively intercepted, preventing the cooling pipe 57 from becoming clogged. The two scrapers 69 are distributed in a circumferential array along the rotating disk 67, which can fully cover the surface of the filter element 7, making the cleaning more uniform and ensuring that the filter element 7 maintains good filtration performance for a long time.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
