Description

Technical Field

[0001] The utility model relates to the technical field of die-casting molds, in particular to a die-casting mold for a vehicle radiator. Background Art

[0002] Automotive heat sinks, also known as radiators, play a vital role in a vehicle's cooling system. Their performance directly impacts the vehicle's performance and lifespan. Die-casting is typically used in the manufacture of automotive radiators, and the die-casting mold is a key factor in determining radiator quality and production efficiency.

[0003] During the die-casting process of automobile radiators, since the radiator occupies a deeper cavity in the mold, the air in the deeper cavity is not easy to be discharged during the injection of liquid metal, which can easily cause bubbles to form inside or on the outer surface of the product, thereby directly affecting the quality of the product. In the existing technology, air is usually discharged by opening an exhaust channel, but during the process of liquid metal being injected into the cavity, part of the liquid metal can easily enter the exhaust channel, causing the exhaust channel to be blocked and affecting the exhaust effect. Utility Model Content

[0004] (1) Technical problems solved

[0005] In response to the shortcomings of the existing technology, the utility model provides a die-casting mold for automotive radiators, which can keep the mold's exhaust channel unobstructed to avoid being blocked by liquid metal, thereby avoiding the problem of bubbles in the finished product, and solving the above-mentioned technical problems.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A die-casting mold for a vehicle radiator, comprising a fixed mold and a movable mold, one side of the fixed mold being connected to a fixed seat by bolts, one side of the movable mold being connected to a movable seat by bolts, and an L-shaped exhaust channel being opened inside the movable mold, the L-shaped exhaust channel being connected to a transverse air channel, one end of the transverse air channel being threadedly connected to an air nozzle, one end of the air nozzle being fixedly connected to a hose, one end of the hose being connected to a one-way valve 1, one end of the one-way valve 1 being threadedly connected to a sleeve, a piston being slidably connected inside the sleeve, the center of the end face of the piston being fixedly connected to a push rod, one end of the push rod being connected to the output end of cylinder No. 1, and a one-way valve 2 being installed on the outer surface of the sleeve.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 4A die-casting mold for a car radiator includes a fixed mold 1 and a movable mold 2. One side of the fixed mold 1 is connected to a fixed seat 3 by bolts, and one side of the movable mold 2 is connected to a movable seat 4 by bolts. An L-shaped exhaust channel 5 is opened inside the movable mold 2, and the L-shaped exhaust channel 5 is connected to a transverse air channel 6. One end of the transverse air channel 6 is threadedly connected to an air nozzle 7, and one end of the air nozzle 7 is fixedly connected to a hose 8. One end of the hose 8 is connected to a one-way valve 9, and one end of the one-way valve 9 is threadedly connected to a sleeve 10. A piston 11 is slidably connected to the sleeve 10, and the center of the end face of the piston 11 is fixedly connected to a push rod 12. One end of the push rod 12 is connected to the output end of the No. 1 cylinder 13, and a one-way valve 24 is installed on the outer surface of the sleeve 10.

[0028] Specifically, lugs 14 are fixedly connected to both sides of the movable base 4. Guide rods 15 are slidably connected within the lugs 14. One end of the guide rods 15 is connected to the first support plate 16, and the other end of the guide rods 15 is connected to the second support plate 17. The advantage is that by activating the second cylinder 18 and causing its output end to drive the movable base 4 to slide, the two lugs 14 can slide on the outer surfaces of the guide rods 15, thus driving the precise displacement of the movable mold 2 and closing it with the fixed mold 1.

[0029] Specifically, a second air cylinder 18 is mounted on the outer surface of the second support plate 17. The output end of the second air cylinder 18 is connected to the movable base 4. The outer surface of the fixed mold 1 is fixedly connected to the liquid inlet pipe 19. Advantageously, when the fixed mold 1 and the movable mold 2 are closed, a liquid inlet funnel is provided on the outer surface of the liquid inlet pipe 19. By injecting liquid metal into the liquid inlet funnel, the liquid metal can enter the liquid inlet pipe 19. In the prior art, an extrusion assembly is provided within the liquid inlet pipe 19 to push the liquid metal into the fixed mold 1, thereby producing a heat sink through the cooperation of the fixed mold 1 and the movable mold 2.

[0030] Specifically, an ejection hole 20 is formed through the outer surface of the movable mold 2, and an ejector pin 21 is inserted into the ejection hole 20. One end of the ejector pin 21 is fixedly connected to the fixed plate 22, and the bottom of the fixed plate 22 is fixedly connected to the base 23. The advantage is that when the fixed mold 1 and the movable mold 2 are closed and liquid metal is injected, a heat sink is formed after cooling. The movable mold 2 is reset by the reset cylinder 18. During the reset process of the movable mold 2, the ejector pin 21 is inserted into the ejection hole 20, so that the ejector pin 21 can contact the formed heat sink, thereby automatically ejecting the heat sink from the movable mold 2.

[0031] Specifically, multiple L-shaped exhaust channels 5 are provided inside the movable mold 2, with the top ends of the L-shaped exhaust channels 5 extending to the top surface of the movable mold 2. This has the advantage that, after the fixed mold 1 and movable mold 2 are closed and liquid metal is injected, the injection pressure allows the liquid metal to enter the cavity inside the movable mold 2. Gas is then discharged through the L-shaped exhaust channels 5, ensuring that the cavity is fully filled with liquid metal. This prevents the formation of pores on the outer surface or inside the heat sink after molding, thereby improving the quality of the heat sink.

[0032] Specifically, the end of the sleeve 10 away from the one-way valve 9 is fixedly connected to the outer surface of the first support plate 16, and the output end of the first cylinder 13 penetrates the first support plate 16 and is fixedly connected to the piston 11. The advantage is that after the formed heat sink is ejected from the movable mold 2, the first cylinder 13 is activated to drive the piston 11 to move within the sleeve 10, thereby injecting the air in the sleeve 10 into the hose 8. The hose 8 then injects the air into the transverse air channel 6 through the air nozzle 7. The air is then diverted into each L-shaped exhaust channel 5. In this way, the metal debris remaining in the L-shaped exhaust channel 5 can be carried out by the gas, thereby preventing the L-shaped exhaust channel 5 from being blocked by residual metal liquid.

[0033] When in use, first start the No. 2 cylinder 18 to make its output end drive the movable seat 4 to slide, and the two ear blocks 14 can slide on the outer surface of the guide rod 15, so that the movable mold 2 can be accurately displaced and closed with the fixed mold 1, and then the liquid metal is injected into the liquid inlet pipe 19, and then the extrusion device in the prior art is used to squeeze the molten metal into the cavities of the fixed mold 1 and the movable mold 2. In the process of injecting liquid metal, the gas can be discharged through the L-shaped exhaust channel 5, and a heat sink is formed after cooling. The movable mold 2 is reset by resetting the No. 2 cylinder 18. In the process of resetting the movable mold 2, The ejector pin 21 is inserted into the ejection hole 20 so that the ejector pin 21 can contact the formed heat sink, thereby automatically ejecting the heat sink from the movable mold 2. Then, by starting the No. 1 cylinder 13, it drives the piston 11 to move in the sleeve 10, so that the air in the sleeve 10 can be injected into the hose 8, and then the hose 8 injects the air into the horizontal air channel 6 through the air nozzle 7, and then the air will be diverted into each L-shaped exhaust channel 5, so that the metal debris remaining in the L-shaped exhaust channel 5 can be carried out by the gas, thereby preventing the L-shaped exhaust channel 5 from being blocked by residual metal liquid.
