Description

Technical Field

[0001] This utility model relates to the technical field of automotive injection molds, specifically a rapid water cooling mechanism for automotive headlight cover injection molds. Background Technology

[0002] The production of automotive parts is inseparable from injection molds, such as car headlight covers and steering wheels. When producing car headlight cover parts using injection molds, rapid cooling devices are needed to speed up the production efficiency of the injection molds.

[0003] A rapid water cooling mechanism for a mold used in metal castings, disclosed in publication number CN115138827A, includes a water cooling box filled with cooling water; a lower mold is disposed inside the water cooling box, with the cooling water level below the top of the lower mold; an electric push rod is disposed above the water cooling box, with the bottom end of the electric push rod connected to an upper mold, and the upper mold and the lower mold are engaged to form a casting cavity;

[0004] The aforementioned document describes how the lower mold is submerged in cooling water for cooling. Simultaneously, a liftable upper mold is used, with a water-passing cavity inside, equipped with a water pump for pumping water. Cooling water passes through an upper water pipe, a heat dissipation cylinder, a flexible pipe, and a suction pipe, entering the water-passing cavity to cool the upper mold. The water is then drained back into the water-cooling box via a drain pipe. This allows for rapid water cooling of both the upper and lower molds.

[0005] However, the aforementioned document uses a cooling fan to blow air onto the serpentine coil to cool the internal cooling water. But since the cooling water is inside the serpentine coil and blocked by the coil body, the cooling effect on the internal cooling water is poor. Furthermore, the aforementioned document uses an electric push rod to eject the injection mold, but the electric push rod is located above the water-cooling box, which seriously affects the ejection of the injection mold and the core. Therefore, we propose a rapid water-cooling mechanism for automotive headlight cover injection molds to solve the problems mentioned above. Utility Model Content

[0031] 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.

[0032] Please see Figure 1-5This utility model provides a technical solution: a rapid water cooling mechanism for an injection mold of an automotive headlight cover, including a cooling box 1, a base box 4, a water pump 10, and a servo motor 22. The cooling box 1 has a cooling tank 2 inside, and inner cavities 8 are formed at the four corners of the cooling box 1. Cooling guide plates 3 are uniformly fixed to the surfaces of the inner cavities 8 and the cooling tank 2. The cooling guide plates 3 are made of copper and are evenly distributed on the inner surface of the cooling box 1, facilitating the transfer of cold air generated by the condenser pipe 9 to the interior through the use of the copper cooling guide plates 3, thus enabling rapid cooling of the injection mold. A base box 4 is installed at the bottom of the cooling box 1. Air inlets 5 are uniformly formed on the upper side of one side of the base box 4. A partition 6 is fixedly installed inside the base box 4 near the air inlets 5, and a water inlet 7 is provided on one side of the base box 4. A water passage hole 25 is formed at the lower end of the partition 6. A condenser pipe 9 is installed in the inner cavity 8 of the cooling box 1. A cold water chamber 13 is provided on the inner side near the air inlet 5, and a water pump 10 is installed at the bottom of the inner side of the cold water chamber 13. The other end of the water pump 10 is connected to the bottom of the bottom box 4 through the water guide pipe 24. One end of the water pump 10 is connected to the condenser pipe 9, and the other end of the water pump 10 is connected to the drain pipe 11. Water outlets 12 are evenly installed on the lower surface of the end of the drain pipe 11 away from the water pump 10, and the water outlets 12 are set at an inclination. Two sets of water outlets 12 are symmetrically arranged about the central axis of the drain pipe 11. The cooling water flowing inside the condenser pipe 9 can be discharged through the drain pipe 11 at the end of the condenser pipe 9 through the water outlets 12 at the end of the drain pipe 11. A top plate 14 is installed at the bottom of the cold water chamber 13. The bottom of the cold water chamber 13 is set at an inclination. The inclination of the bottom of the cold water chamber 13 facilitates the discharge of the cold water through the water passage holes 25 on the surface of the partition plate 6 into the interior of the bottom box 4 for the reuse of the cooling water.

[0033] Please see Figure 1-5, the top plate 14 is located below the air inlet hole 5, and blowing fans 15 are evenly installed on the surface of the top plate 14. The blowing fans 15 are symmetrically arranged about the central axis of the top plate 14. By using the blowing fans 15 on the surface of the top plate 14, it is convenient to blow and dissipate the heat of the cooling water discharged from the condensation pipe 9, so as to blow and cool the cooling water with temperature and improve the use effect of the device. A bottom plate 16 is arranged inside the bottom box 4. Four corners of the upper surface of the bottom plate 16 are fixed with top columns 17. The surface of the bottom plate 16 is arranged in a hollow shape, and springs 18 connected to the bottom of the cooling box 1 are fixed on the outer surface of the top columns 17 on the upper surface of the bottom plate 16. By using the top columns 17 on the surface of the bottom plate 16, it is convenient to eject the injection mold inside the cooling box 1 through the surrounding top columns 17, so as to quickly discharge the injection mold. At the left and right ends below the bottom plate 16 inside the bottom box 4, a first connecting shaft 19 and a second connecting shaft 20 are rotationally connected. Connecting frames 21 are fixed on the surfaces of the first connecting shaft 19 and the second connecting shaft 20. A servo motor 22 connected to the first connecting shaft 19 is fixed at the outer end of the bottom of the bottom box 4. Rotating gears 23 are fixed on the surfaces of the first connecting shaft 19 and the second connecting shaft 20 at the outer end of the bottom box 4, and the rotating gear 23 on the surface of the first connecting shaft 19 and the rotating gear 23 on the surface of the second connecting shaft 20 are meshed. By using the meshed rotating gears 23 on the surfaces of the first connecting shaft 19 and the second connecting shaft 20, it is convenient for the first connecting shaft 19 and the second connecting shaft 20 to drive the connecting frames 21 to rotate towards each other. The connecting frames 21 are arranged in a "square" shape, and the upper end surface of the connecting frames 21 is in contact with the lower end surface of the bottom plate 16. When the connecting frames 21 rotate, it is convenient to drive the bottom plate 16 to move upward, so as to eject the mold. At the same time, with the reset of the spring 18, when the connecting frames 21 are reset, the bottom plate 16 is reset.

[0034] Working principle: First, during use, the injection mold is placed in the cooling groove 2 inside the cooling box 1. By turning on the water pump 10, the water pump 10 sucks the cooling water inside the bottom box 4 through the water conduit 24 and discharges it into the condensation pipe 9, so as to cool the inside of the cooling box 1, enabling the cold air to be transmitted to the internal injection mold through the cold conduction plate 3 inside the cooling groove 2, facilitating the cooling of the injection mold. A drain pipe 11 is arranged above the end of the condensation pipe 9 in the cold water cavity 13, which is convenient for discharging the cooled cooling water with temperature through the water outlet head 12. Above the drain pipe 11, there is a top plate 14. The blowing fans 15 on the surface of the top plate 14 can blow the discharged cooling water, so as to quickly cool the cooling water. The cooled cooling water will be discharged into the inside of the bottom box 4 through the water passing holes 25 at the end of the partition plate 6, facilitating the recycling of the cooling water;

[0035] During material discharge, the servo motor 22 can be turned on, causing the first connecting shaft 19 to rotate, which in turn causes the connecting frame 21 to rotate. The ends of the first connecting shaft 19 and the second connecting shaft 20 are fixed with meshing rotating gears 23, which allows the second connecting shaft 20 to rotate synchronously as the rotating gears 23 rotate. This allows the two sets of connecting frames 21 to move towards each other, pushing the base plate 16 upwards. The base plate 16 then pushes the top pillars 17 fixed at the four corners out from the inner surface of the cooling tank 2, thus facilitating the discharge of the injection mold from the cooling box 1. The top pillars 17 on the base plate 16 are connected to the bottom of the cooling box 1 by springs 18, which allows the base plate 16 to be reset, improving the efficiency of the device. This is the operating principle of the rapid water cooling mechanism for the automotive headlight cover injection mold.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
