[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example

[0030] like Figure 1-9 As shown, an embodiment of the present invention provides a gear casting mold, including a lower mold base 1 and an upper mold base 2. A water storage box 3 is disposed below the lower mold base 1. The lower mold base 1 is fixed to the top of the water storage box 3 by four columns. A lifting assembly 4 for raising and lowering the upper mold base 2 is disposed on the lower mold base 1. A pouring port 5 is fixedly connected to the top of the upper mold base 2. An ejection assembly 6 for ejecting the formed gear is disposed on the lower mold base 1. An L-shaped lever 7 for actuating the ejection assembly 6 is fixedly fixed to the back of the upper mold base 2. A flow channel is opened inside the lower mold base 1, and connecting pipes 8 are fixedly connected to both ends of the flow channel. An annular air blowing pipe 9 is disposed on the outside of the lower mold base 1. An auger 10 is rotatably installed inside the water storage box 3 through bearings. A strip-shaped air blowing pipe 11 is fixedly installed on the top of the water storage box 3 through two support blocks. The top of the enclosure is fixed to the housing 12 by four support rods. An opening is provided on one side wall of the housing 12, and a wet curtain 13 is fixedly covered at the opening. A blower assembly 14 is provided on the housing 12 for blowing air to the annular blower pipe 9 and the strip blower pipe 11. A water pump assembly 15 is provided on the housing 12 for supplying water to an adjacent connecting pipe 8 and the wet curtain 13. A return water pipe 16 is fixedly connected to the surface of another connecting pipe 8 away from the housing 12. A drive assembly 17 is provided on the housing 12 for driving the blower assembly 14 and the water pump assembly 15 and driving the auger 10 to reciprocate forward and reverse. A drain pipe 18 is fixedly connected to the bottom of the housing 12. A water collection trough 20 is provided on the inner wall of the bottom of the housing 12, and the water collection trough 20 is located directly below the wet curtain 13. The drain pipe 18 is connected to the water collection trough 20.

[0031] In use, a release agent is first sprayed into the mold cavity of the lower mold base 1. Then, molten metal is injected into the mold cavity of the lower mold base 1 through the pouring port 5. The drive assembly 17 drives the blower assembly 14 and the water pump assembly 15 to operate, and drives the auger 10 to reciprocate in both forward and reverse directions. The water pump assembly 15 pumps the water contained in the water storage box 3 into a connecting pipe 8, and then into the flow channel of the lower mold base 1. The water passing through the flow channel falls back into the water storage box 3 through another connecting pipe 8 and the return water pipe 16. At the same time, the water pump assembly 15 can also transport the water in the water storage box 3 to the wet curtain 13. The water passing through the wet curtain 13 will fall back into the water storage box 3 through the drain pipe 18, thus saving water. The blower assembly 14 operates to draw air from the outside environment into the box 12. The outside air passes through the wet curtain 13, and the water molecules come into full contact with the air, thus evaporating quickly. According to the principle of evaporation heat absorption, the air temperature will decrease. The system blows out cooler air, which enters the annular air duct 9 and blows air onto the surface of the lower mold base 1. This provides a dual cooling effect of water and air cooling for the lower mold base 1. The cooler air also enters the strip air duct 11 and blows air onto the water in the water storage box 3. The reciprocating motion of the auger 10 agitates the water in the water storage box 3, allowing heat to be transferred from the center of the water to the surface more quickly. This increases the contact area between the water and the air and accelerates airflow, thereby speeding up the heat dissipation of the water in the water storage box 3. This further improves the overall heat dissipation effect, resulting in a faster cooling rate for the molten metal material and a faster gear forming rate. After the gear has cooled and formed, the lifting component 4 controls the upper mold base 2 to move upward. The upper mold base 2 then moves the L-shaped lever 7 upward, which in turn moves the ejector component 6, ejecting the gear from the mold cavity of the lower mold base 1 for easy removal by the operator.

[0032] like Figure 1 , Figure 4 and Figure 5As shown, in this embodiment, the lifting assembly 4 includes a U-shaped plate 401 fixed to the top of the lower mold base 1. Suspension members 19 are fixed to both sides of the U-shaped plate 401. The annular air pipe 9 is fixedly connected to the two suspension members 19. The suspension members 19 are used to improve the stability of the annular air pipe 9. A cylinder 402 is fixed to the top of the U-shaped plate 401. The ejector end of the cylinder 402 slides through the top of the U-shaped plate 401 and is fixedly connected to the top of the upper mold base 2. Two T-shaped rods 403 symmetrically slide through the top of the U-shaped plate 401. The bottoms of the two T-shaped rods 403 are fixedly connected to the top of the upper mold base 2. When it is necessary to control the upper mold base 2 to move upward, the cylinder 402 can be activated. The retraction of the ejector end of the cylinder 402 can drive the upper mold base... 2. Move upwards; Ejector assembly 6 includes a spring 601 fixed to the bottom of the lower mold base 1. A connecting plate 602 is fixed to the bottom end of the spring 601. Four ejector rods 603 are fixed in a circumferential array on the top of the connecting plate 602. The four ejector rods 603 slide through the bottom of the lower mold base 1 and extend into the mold cavity of the lower mold base 1. The bottom end of the L-shaped baffle 7 is located below the connecting plate 602. When the upper mold base 2 moves upwards, it will drive the L-shaped baffle 7 to move upwards. When the bottom end of the L-shaped baffle 7 is in contact with the bottom of the connecting plate 602, the L-shaped baffle 7 continues to move upwards, which will drive the connecting plate 602 to move upwards. At this time, the spring 601 will be compressed, and the connecting plate 602 will drive the four ejector rods 603 to move upwards, thereby ejecting the gear in the mold cavity of the lower mold base 1.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 9 As shown, in this embodiment, the blower assembly 14 includes a mounting base 1401 fixed inside the housing 12.
