Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a rapid cooling device for injection molds for automotive connector housings. Background Technology

[0002] The rapid cooling device for injection molds is an auxiliary device in the injection molding process. Its function is to quickly reduce the temperature of the injection mold through efficient cooling medium circulation, so that the injection-molded plastic products can solidify and form quickly, thereby improving production efficiency and ensuring product quality stability.

[0003] The rapid cooling device for automotive connector housing injection molds is a cooling system specifically designed for the injection molding production of automotive connector housings. This device requires precise control of the cooling process to meet the injection molding requirements of automotive connector housings. By rationally arranging cooling channels inside the mold and optimizing the flow path of the cooling medium, differentiated cooling of different parts of the mold is achieved, ensuring uniform cooling of the automotive connector housing during the injection molding process.

[0004] Traditional cooling pipe layouts are determined during mold manufacturing and cannot adapt to the complex and diverse structures of different automotive connector housings. Existing technologies employ adjustable cooling pipe systems, reserving multiple installation positions during mold design. The cooling pipe layout can be flexibly adjusted according to different connector housing models to ensure a close fit to the complex structure of the housing and achieve uniform cooling. However, after long-term use, the cooling medium will contain impurities, which will adhere to the inner wall of the cooling pipes, causing blockages and preventing the mold from cooling effectively, thus affecting the product molding quality.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0034] Reference Figure 2 , Figure 3 and Figure 4This utility model provides an embodiment of a rapid cooling device for an injection mold of an automotive connector housing. It includes an operating table 1, providing a support platform. A fixed mold base 5 is fixedly connected to the top right side of the operating table 1, for mounting a fixed template 12. The fixed template 12 is also fixedly connected to the left side of the fixed mold base 5. The fixed template 12 and a moving template 7 cooperate to form an injection cavity. Multiple guide rods 6 are slidably connected to the inner walls of both the fixed mold base 5 and the fixed template 12. The guide rods 6 ensure the smoothness and accuracy of the movement of the moving template 7. The left ends of the multiple guide rods 6 are all fixedly connected to the same moving template 7. The moving template 7 moves on the guide rods 6 to achieve mold opening and closing. A filter mechanism 2 is provided at the bottom of the operating table 1 to filter the coolant and prevent pipe blockage. A drive mechanism 4 is located on the top left side of the operating platform 1. The drive mechanism 4 provides power to drive the moving platen 7. Circulation mechanisms 8 are located on both the front and rear sides of the filtering mechanism 2, enabling the circulation of coolant. A discharge mechanism 9 is located at the bottom of the filtering mechanism 2, discharging filtered impurities. An ejection and replacement mechanism 3 is located on the inner wall of the moving platen 7, used to eject the mold after injection molding. The filtering mechanism 2 includes two connecting blocks 201, which fix the filter tube 202 to the bottom of the operating platform 1. The tops of both connecting blocks 201 are fixedly connected to the bottom of the operating platform 1, and the inner walls of both connecting blocks 201 are fixedly connected to the same filter tube 202, which filters the coolant. The filter tube 202 has a channel with a coarse filter screen 203 fixedly connected to the front of its inner wall. The coarse filter screen 203 intercepts larger particles of impurities. A medium filter screen 204 is fixedly connected to the middle of the inner wall of the filter tube 202. The medium filter screen 204 further filters medium-sized particles of impurities. A fine filter screen 205 is fixedly connected to the rear of the inner wall of the filter tube 202. The fine filter screen 205 removes tiny particles of impurities. A settling tank 206 is fixedly connected to the bottom of the filter tube 202. The settling tank 206 collects the filtered impurities. A vibration motor 207 is fixedly connected to the top of the filter tube 202. The vibration motor 207 causes the impurities to fall off the filter screen into the settling tank 206. The drive mechanism 4 includes a mounting plate 401, which fixes the hydraulic rod 402 and provides support. The bottom of mounting plate 401 is fixedly connected to the top left side of the operating platform 1. A hydraulic rod 402 is fixedly connected to the right side of mounting plate 401. The hydraulic rod 402 pushes and pulls the moving template 7 to move. The circulation mechanism 8 includes a main inlet pipe 801, which delivers coolant to the mold. The rear end of the main inlet pipe 801 is fixedly connected to the front side of the filter pipe 202. A circulating water pump 802 is fixedly connected to the bottom end of the main inlet pipe 801, which provides power for the circulation of coolant. A cooling tank 803 is fixedly connected to the middle of the main inlet pipe 801, which reduces the temperature of the coolant. Two branch inlet pipes 804 are fixedly connected to the rear end of the filter pipe 202, which introduce coolant into the moving template 7 and the fixed template 12 respectively.The tops of two inlet branch pipes 804 are fixedly connected to the front bottom of the moving mold plate 7 and the fixed mold plate 12, respectively. Both the moving mold plate 7 and the fixed mold plate 12 have outlet branch pipes 805 fixedly connected to their rear bottoms. The outlet branch pipes 805 collect the coolant inside the mold. The bottoms of both outlet branch pipes 805 are fixedly connected to the same main outlet pipe 806. The main outlet pipe 806 collects the coolant and returns it to the circulating water pump 802. The bottom end of the main outlet pipe 806 is fixedly connected to the rear top of the circulating water pump 802. The discharge mechanism 9 includes an impurity discharge pipe 901, which discharges impurities from the settling tank 206. The top of the impurity discharge pipe 901 is fixedly connected to the bottom of the settling tank 206, and a drain valve 902 is fixedly connected to the middle of the impurity discharge pipe 901. The drain valve 902 controls the discharge of impurities.

[0035] Specifically, the hydraulic rod 402 in the drive mechanism 4 pushes the moving mold plate 7, moving it closer to and further away from the fixed mold plate 12 along the guide rod 6, completing the mold opening and closing action. The circulating water pump 802 draws coolant from the cooling tank 803 through the inlet manifold 801. The coolant then flows through the inlet branch pipe 804 into the cooling channels of the moving mold plate 7 and the fixed mold plate 12, respectively, carrying away the heat generated by the mold during injection molding. Subsequently, the coolant carrying heat is collected through the outlet branch pipe 805 into the outlet manifold 806, and then returns to the circulating water pump 802, forming a circulating cooling system. During this process, the filtration mechanism 2 starts working. The coolant containing impurities flows from the circulating mechanism 8 into the filter pipe 202, first passing through the coarse filter screen 203, where larger particles of impurities are intercepted, preventing them from entering the subsequent filter layers. Then, the coolant... As the coolant flows through the medium filter screen 204, medium-sized impurities are further filtered. Finally, the fine filter screen 205 removes tiny particulate impurities, thus achieving three-stage filtration of the coolant. During the filtration process, the vibration motor 207 works continuously, causing impurities attached to the filter screen to fall off quickly through the vibration filter tube 202 and into the settling tank 206 below. When impurities accumulate to a certain level in the settling tank 206, the discharge mechanism 9 starts to function, opening the drain valve 902, and the impurities are discharged through the impurity discharge pipe 901, ensuring that the settling tank 206 can continuously and effectively collect impurities. This effectively solves the problem in the prior art where impurities in the cooling medium cause blockage of the cooling pipes, which in turn affects mold cooling and product molding quality, thus ensuring the stable operation of the injection mold cooling system and product quality.

[0036] Reference Figure 2 , Figure 5 and Figure 6The ejector changing mechanism 3 includes multiple ejector rods 301. The ejector rods 301, as the main components of the ejector mold, transmit ejection power. Ejector heads 302 are slidably connected to the inner walls of each ejector rod 301. The ejector heads 302 directly contact the mold after injection molding, providing ejection force. Each ejector head 302 has a slot 303 at its bottom, which engages with a positioning block 304 to achieve positioning and connection of the ejector head 302. The inner walls of each slot 303 are slidably connected to the positioning block 304. 4. The ejector head 302 can slide within the slot 303, facilitating its installation and removal. Multiple engaging positioning blocks 304 have springs 305 fixedly connected to their bottoms. These springs 305 provide elastic cushioning for the ejector head 302, ensuring more even force distribution on the mold during ejection. The outer walls of the multiple springs 305 are slidably connected to the inner walls of their corresponding ejector pins 301. Each ejector pin 301 has a fixing screw 306 at its top right end. These screws secure the ejector head 302, preventing it from falling off during ejection. 306 passes through the outer wall of the corresponding push rod 301 and is threaded to the inner wall of the push head 302. Each push rod 301 has a reset assembly 307 on its outer wall. The reset assembly 307 ensures that the push rod 301 returns to its initial position after completing the ejection action. The reset assembly 307 includes multiple reset springs 3071. The reset springs 3071 store and release elastic potential energy to drive the push rod 301 to reset. The inner walls of the multiple reset springs 3071 are slidably connected to the outer wall of the corresponding push rod 301. Each of the multiple fixed blocks 3072 is fixedly connected to the left end of the push rod 301. The fixed blocks 3072 fix one end of the return spring 3071 to the push rod 301. The inner walls of the multiple fixed blocks 3072 are fixedly connected to the left side of the outer wall of the corresponding push rod 301. Each of the multiple return springs 3071 is fixedly connected to the right end of the push rod 301. The sliding blocks 3073 slide on the push rod 301 to transmit the force of the return spring 3071. The inner walls of the multiple sliding blocks 3073 are slidably connected to the right side of the outer surface of the corresponding push rod 301.

[0037] Specifically, since a fixing screw 306 is provided at the top right end of the outer wall of the push rod 301, the fixing screw 306 penetrates the outer wall of the push rod 301 and is threaded to the inner wall of the push head 302. First, unscrew the fixing screw 306 at the top right end of the outer wall of the push rod 301 to release its threaded connection with the inner wall of the push head 302. At this time, because the bottom slot 303 of the push head 302 is slidably connected to the engaging positioning block 304, pull out the push head 302. The engaging positioning block 304 is released from the constraint of the slot 303, and the worn push head 302 can be easily pulled upwards. When installing a new push head 302, align the bottom slot 303 of the new push head 302 with the engaging positioning block 304 and insert it. The engaging positioning block 304 slides into the slot 303 to complete the positioning. Then tighten the fixing screw 306 to place the push head 302. Securely fixed to the ejector rod 301, the installation is completed, enabling quick replacement of the ejector head 302. When the hydraulic rod 402 in the drive mechanism 4 retracts, it drives the ejector rod 301 of the associated ejection replacement mechanism 3 to move to the left. When the ejector rod 301 contacts the mounting plate 401, the mounting plate 401 prevents the ejector rod 301 from moving further to the left. At this time, the thrust of the ejector rod 301 is transmitted to the mold, thereby ejecting the mold. After the mold is ejected, the hydraulic rod 402 extends, the return spring 3071 releases its elastic potential energy, and pushes the sliding ejector block 3073 to drive the ejector rod 301 to return to the right, preparing for the next injection molding ejection. This allows for quick replacement of the worn ejector head 302, reducing downtime. The return assembly 307 also ensures that the ejector rod 301 returns to its original position in a timely manner, improving production efficiency and stability.

[0038] Reference Figure 1 and Figure 2 Multiple guide rods 6 are fixedly connected to the right end of the outer wall of each guide rod 6. The limit block 10 is used to limit the movement position of the moving template 7 on the guide rod 6 to prevent it from moving excessively and detaching from the fixed mold base 5 and the fixed template 12. Multiple limit blocks 10 are fixedly connected to the left side of each buffer pad 11. The buffer pad 11 can buffer when the moving template 7 approaches the fixed mold base 5, reduce the impact force of the collision, and protect the mold. The left side of multiple buffer pads 11 is respectively attached to the four corners of the right side of the fixed mold base 5. The inner wall of the settling tank 206 is funnel-shaped. This shape design is conducive to the impurities filtered down naturally gathering to the bottom of the settling tank 206 under the action of gravity, which is convenient for the collection of impurities. The left side of multiple fixing blocks 3072 is attached to the right side of the mounting plate 401. The mounting plate 401 provides support for the fixing blocks 3072, thereby ensuring that the reset spring 3071 plays a stable role during the reset process of the push rod 301.

[0039] Specifically, the limiting block 10 is used to limit the movement of the moving template 7 on the guide rod 6 to prevent it from moving excessively and detaching from the fixed mold base 5 and the fixed template 12. The buffer pad 11 can buffer the moving template 7 when it approaches the fixed mold base 5, reduce the impact force of the collision, and protect the mold. The inner wall of the settling tank 206 is funnel-shaped. This shape design is conducive to the natural accumulation of filtered impurities to the bottom of the settling tank 206 under the action of gravity, which is convenient for the collection of impurities. The fixing block 3072 is supported by the mounting plate 401, while ensuring that the return spring 3071 plays a stable role during the reset process of the push rod 301.

[0040] Working principle: When the injection mold is working, the hydraulic rod 402 in the drive mechanism 4 pushes the moving platen 7, which moves closer to and further away from the fixed platen 12 along the guide rod 6, completing the opening and closing action of the mold. The circulating water pump 802 draws the coolant from the cooling tank 803 through the inlet main pipe 801. The coolant then flows through the inlet branch pipe 804 into the cooling channels of the moving platen 7 and the fixed platen 12, respectively, carrying away the heat generated by the mold during the injection process. Subsequently, the coolant carrying heat is collected through the outlet branch pipe 805 into the outlet main pipe 806, and then returns to the circulating water pump 802, forming a circulating cooling. During this process, the filtration mechanism 2 starts to work. The coolant containing impurities flows from the circulation mechanism 8 into the filter pipe 202, first passing through the coarse filter screen 203, where larger particles of impurities are intercepted, preventing them from entering the subsequent filter layers. As the coolant flows through the medium filter 204, medium-sized impurities are further filtered. Finally, the fine filter 205 removes tiny particulate impurities, thus achieving three-stage filtration of the coolant. During the filtration process, the vibration motor 207 works continuously, causing the impurities attached to the filter screen to fall off quickly through the vibration filter tube 202 and fall into the settling tank 206 below. When the impurities in the settling tank 206 accumulate to a certain level, the discharge mechanism 9 starts to function, opening the drain valve 902, and the impurities are discharged through the impurity discharge pipe 901, ensuring that the settling tank 206 can continuously and effectively collect impurities. This effectively solves the problem in the prior art where impurities in the cooling medium cause blockage of the cooling pipes, which in turn affects mold cooling and product molding quality, thus ensuring the stable operation of the injection mold cooling system and product quality.

[0041] Furthermore, when the top head 302 becomes worn and needs replacement, a fixing screw 306 is installed at the top right end of the outer wall of the top rod 301. The fixing screw 306 penetrates the outer wall of the top rod 301 and is threaded to the inner wall of the top head 302. First, unscrew the fixing screw 306 at the top right end of the outer wall of the top rod 301 to release its threaded connection with the inner wall of the top head 302. At this time, because the bottom slot 303 of the top head 302 is slidably connected to the engaging positioning block 304, pull out the top head 302. The engaging positioning block 304 is released from the constraint of the slot 303, and the worn top head 302 can be easily pulled upwards. When installing a new top head 302, align the bottom slot 303 of the new top head 302 with the engaging positioning block 304 and insert it. The engaging positioning block 304 slides into the slot 303 to complete the positioning. Then tighten the fixing screw 306. The ejector head 302 is securely fixed to the ejector rod 301, completing the installation and enabling quick replacement of the ejector head 302. When the hydraulic rod 402 in the drive mechanism 4 retracts, it drives the ejector rod 301 of the associated ejection replacement mechanism 3 to move to the left. When the ejector rod 301 contacts the mounting plate 401, the mounting plate 401 prevents the ejector rod 301 from moving further to the left. At this time, the thrust of the ejector rod 301 is transmitted to the mold, thereby ejecting the mold. After the mold is ejected, the hydraulic rod 402 extends, the return spring 3071 releases its elastic potential energy, and pushes the sliding ejector block 3073 to drive the ejector rod 301 to return to the right, preparing for the next injection molding ejection. This allows for quick replacement of the worn ejector head 302, reducing downtime. The return assembly 307 also ensures that the ejector rod 301 returns to its original position in a timely manner, improving production efficiency and stability.
