Description

Technical Field

[0001] This utility model relates to the field of metal die casting technology, specifically a circulating cooling type metal die casting mold. Background Technology

[0002] Die casting molds are tools used to cast metal parts, specifically for completing the die casting process on a specialized die casting and forging machine. The basic die casting process involves molten metal being poured into the mold cavity at low or high speed. The mold has movable cavity surfaces, which are pressurized and forged as the molten metal cools. This process eliminates shrinkage cavities and porosity defects in the blank, and also achieves a forged, fragmented grain structure in the blank, significantly improving its overall mechanical properties. After mold production, the mold retains heat, which needs to be removed before further die casting can proceed. However, the poor heat dissipation of die casting molds affects their normal use; therefore, a circulating cooling die casting mold is required.

[0003] For example, a circulating cooling die-casting mold disclosed in CN212976673U solves the problem that current die-casting molds on the market retain heat after mold production, requiring heat removal before die-casting can continue. This is because the heat dissipation of the die-casting mold itself is poor, affecting its normal use. The mold includes an adapter plate with two fixed support plates symmetrically distributed around the axis of the adapter plate. A die-casting mold is fixedly mounted on the top of each support plate, and a hydraulic cylinder is fixedly mounted on the top of each support plate. The hydraulic cylinder has a hydraulic strut inside, with one side of the top of the hydraulic strut fixedly connected to one side of the die-casting mold. This invention allows the cover plate of the die-casting mold to be raised and lowered, facilitating the removal of the die-casting mold and accelerating the production efficiency of the die-casting mold.

[0004] The aforementioned patent facilitates the removal of the die-casting mold and solves the problem of poor heat dissipation of the die-casting mold itself by spraying water for cooling. However, the device only sprays water for cooling in two die-casting cycles without collecting and recycling the cooling water, which consumes a lot of water during the production process and wastes water resources.

[0005] Therefore, we propose a circulating cooling type die-casting mold for metal parts to solve the problems mentioned above. Utility Model Content

[0025] 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.

[0026] Please see Figure 1-3 This utility model provides a technical solution: a circulating cooling type die-casting mold for metal parts, including a lower mold 1 and an upper mold 2 movably mounted above the lower mold 1. Support legs 3 are fixedly mounted at the four corners of the lower end of the lower mold 1. A water pump 81 and a water pump 44 are mounted at the lower end of the lower mold 1. The mold also includes: A cooling box 4 is fixedly installed at the lower end of the lower mold 1. A cavity 43 is fixedly installed inside the cooling box 4.

A first water outlet pipe 46 is fixedly installed at the outlet end of the second water pump 44. Two first water outlet pipes 41 are fixedly installed on the side wall of the cooling box 4. A connecting pipe 47 is fixedly installed on the inner wall of the cooling box 4 and is connected to the first water outlet pipe 46 and the first water outlet pipe 41. The first water outlet pipe 41 is connected to the lower mold 1 and the upper mold 2. A first water supply pipe 52 is installed on the side wall of the lower mold 1 and the upper mold 2 and is connected to the lower mold 1, the upper mold 2 and the cooling box 4.

[0027] When cooling of the mold is required, the cooling tank 4 is connected to the lower mold 1 and the lower mold 2 through pipes. The other ends of the lower mold 1 and the lower mold 2 are then connected to the cooling tank 4 through the water supply pipe 52. After the connection is completed, the water pump 44 is started. The water pump 44 delivers the coolant in the cooling tank 4 into the outlet pipe 46 through the suction pipe 45. Then, the coolant enters the connecting pipe 47 through the outlet pipe 46. The coolant in the connecting pipe 47 flows to both sides and enters the lower mold 1 and the upper mold 2 to cool the mold. After flowing through the lower mold 1 and the upper mold 2, the coolant flows into the water supply pipe 52 and then into the cooling tank 4. This device can recycle the coolant and save resources.

[0028] Please see Figure 3-5 Both the lower mold 1 and the upper mold 2 have water inlet pipes 48 fixedly installed on their side walls. Water inlet pipe 48 and water outlet pipe 41 are connected by a common threaded water supply pipe 42, which connects the lower mold 1, the upper mold 2 and the cooling box 4.

[0029] A water tank 5 is fixedly installed at the lower end of the lower mold 1. A water inlet pipe 51 is fixedly installed on the side wall of the water tank 5. Water outlet pipes 53 are fixedly installed on the side walls of both the lower mold 1 and the upper mold 2. A water supply pipe 52 connects the lower mold 1, the upper mold 2 and the water tank 5.

[0030] A gas chamber 7 is fixedly installed at the lower end of the lower mold 1. A piston 71 is slidably connected inside the gas chamber 7. Several springs 72 are fixedly installed between the piston 71 and the gas chamber 7. A fixing rod 73 is fixedly installed at the lower end of the piston 71. The gas chamber 7 is filled with an inert gas that is easily expanded by heat.

[0031] A fixing plate 8 is fixedly installed at the lower end of the air chamber 7. A water pump 81 is fixedly installed at the upper end of the fixing plate 8. A suction pipe 83 is fixedly installed at the suction end of the water pump 81. The suction pipe 83 is connected to the inside of the water tank 5. A discharge pipe 84 is fixedly installed at the discharge end of the water pump 81. The discharge pipe 84 is connected to the inside of the cooling box 4.

[0032] A push switch 82 and a push switch 83 are fixedly installed on the upper end of the water pump 81. When the fixed rod 73 slides upward, it can contact the push switch 82. When the fixed rod 73 slides downward, it can contact the push switch 83. The push switch 82 and the push switch 83 are electrically connected to the water pump 81 and the water pump 44, respectively.

[0033] A heat insulation layer 6 is fixedly installed between the cooling box 4, the water tank 5 and the lower mold 1, and the air chamber 7 is in direct contact with the lower mold 1.

[0034] Press switches 82 and 83 are manually controlled to determine whether they are connected to the power supply. When press switches 82 and 83 need to work, the power supply is manually connected, and the water pumps 81 and 44 are automatically controlled.

[0035] When cooling of the mold is required, the cooling tank 4 is connected to the lower mold 1 and the upper mold 2 via water pipe 2 42, and the water tank 5 is connected to the lower mold 1 and the upper mold 2 via water pipe 1 52. Under the influence of the temperature of the lower mold 1 itself, the inert gas in the air chamber 7 expands and pushes the piston 71 to slide on the inner wall of the air chamber 7. At this time, the spring 72 is in a stretched state. When the piston 71 slides, it drives the fixed rod 73 to push down and activate the push switch 1 82. The push switch 1 82 activates the water pump 2 44. At this time, the water pump 2 44 automatically delivers coolant to the lower mold 1 and the upper mold 2. After flowing through the lower mold 1 and the upper mold 2, the coolant flows out through the outlet pipe 2 53 and into the water pipe 1 52. Water pipe 2 51 enters water tank 5. After the temperature of lower mold 1 drops, the thrust on piston 71 in air chamber 7 decreases, and spring 72 automatically pulls piston 71 back to its original position. Fixed rod 73 pushes upward to activate press switch 2 85. At this time, press switch 2 85 starts water pump 1 81. Water pump 1 81 absorbs coolant from water tank 5 through suction pipe 2 83, flows through outlet pipe 2 84, and then enters cooling tank 4 to cool the coolant, preparing it for the next cooling operation. This device can automatically cool the mold and separate the cooled liquid from the liquid that is about to be cooled, avoiding the cooled liquid from affecting the cooling effect. The heat insulation layer reduces the impact of the temperature of lower mold 1 on cooling tank 4 and water tank 5.
