[0026] Compared with the prior art, the invention has the following beneficial effects: the aluminum alloy casting mold with high efficiency demoulding has an adjustable heat dissipation structure arranged on the mold, and when adding molding liquid, the heat dissipation efficiency of the heat dissipation mechanism is reduced by adjusting the heat dissipation mechanism, thereby reducing the temperature difference of the high-temperature liquid; 1. A ejector block is provided. After the upper and lower molds are closed, the upper mold pushes the resistance rod so that the adjustment plate, the resistance rod and the ejector block can move downward. After the molding is gradually completed, when the upper mold is opened, the ejector block and the resistance rod can be reset and rebounded under the action of the first spring. After the reset, the ejector block can eject the molding space in the mold cavity outward, thereby improving the demoulding efficiency of each piece in the mold cavity; 2. A heat insulating column is provided. By rotating the heat insulating column, the heat conducting block and the heat dissipating fins can be misaligned when the flowing liquid is injected, thereby preventing the heat dissipating fins from transferring heat outward through the heat conducting block and reducing the amount of heat transferred. During cooling, the heat insulating column can rotate to align the heat conducting block with the heat dissipating fins for normal heat conduction and cooling. At the same time, after the heat conducting block and the heat dissipating fins are aligned, the first diversion groove on the heat conducting block and the diversion groove in the middle of the heat dissipating fins are aligned with each other. An air pump is used to introduce air into the interior of the heat conducting block. The air flow can enter the interior of the heat dissipating fins along the heat conducting block and be discharged outward from the air outlet pipe. The flow of air flow can increase the cooling speed of the lower mold; 3. A vibration rod is provided. When the heat insulating column rotates to cause the heat conducting block and the heat dissipating fin to be misaligned, the lower end opening of the second diverter groove on the heat insulating column is aligned with the air inlet hole on the limit cover. At this time, when the air pump supplies air to the center tube and the inside of the heat conducting block, the airflow can enter the inside of the limit cover through the second diverter groove and the air inlet hole. The increase of the airflow inside the limit cover can move the piston plate in the direction away from the lower mold. After the piston plate moves, the power magnetic block on it and the power magnetic block at the end of the vibration rod move away from each other. The vibration rod resets and rebounds under the action of the third spring. After the reset, the vibration rod hits the lower mold. The vibration generated by the impact on the lower mold can reduce the bubbles in the liquid injected into the mold cavity. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

Although the heat sink can play a role in heat dissipation and cooling, after the molding liquid is gradually added into the mold cavity, the molding liquid that first enters the mold cavity is cooled by the heat conduction of the heat sink, and it is easy to have a temperature difference with the subsequent poured liquid, thereby reducing the cooling and molding effect of the subsequent liquid as a whole. In order to solve this technical problem, the following technical contents are disclosed in this embodiment: an aluminum alloy casting mold with high efficiency demolding, comprising a lower mold 1, an upper mold 2 is arranged above the lower mold 1, and a mold cavity 3 is opened in the middle of the lower mold 1, a mold core 4 matching the mold cavity 3 is installed in the middle of the lower end of the upper mold 2, and a mold core 4 matching the mold cavity 3 is arranged in the middle of the upper mold 2 There is a fluid channel 5, a jacking and demolding component 6 is installed in the middle of the lower mold 1, and the jacking and demolding component 6 is used to eject the molded casting in the mold cavity 3 when the mold is opened, and a movable heat dissipation component 7 is installed on the side of the lower mold 1, and the movable heat dissipation component 7 slows down the heat dissipation effect when the liquid is passed, and is used to restore the heat dissipation during cooling. The jacking and demolding component 6 includes an adjustment plate 601, and the adjustment plate 601 is located inside the lower mold 1, and the adjustment plate 601 is connected to the inside of the lower mold 1 through a first spring 602, and the upper end of the side of the adjustment plate 601 is fixedly connected with a resistance rod 603, and a ejection block 604 is fixedly installed in the middle of the adjustment plate 601, and the resistance rod 603 and the ejection block 604 are vertically distributed with the adjustment plate 601, and the ejection block 604 is closed. The movable heat dissipation component 7 is symmetrically distributed about the central axis of the adjustment plate 601, and the heat dissipation fin 701 is fixed inside the lower mold 1. A guide groove 702 is opened in the middle of the heat dissipation fin 701, and the guide grooves 702 inside adjacent heat dissipation fins 701 are interconnected through an air outlet pipe 703, and one end of the air outlet pipe 703 extends out of the lower mold 1. An insulation column 704 is arranged at one end of the heat dissipation fin 701 facing the outer side of the lower mold 1, and a heat conduction block 705 is fixedly installed in the middle of the insulation column 704. The middle part of the lower end of the insulation column 704 is installed on the central tube 706, and the interiors of adjacent central tubes 706 are interconnected through a connecting groove 707, and one of the central tubes 706 is connected to the air supply pipe 708. and the air pump 709 are interconnected, an air flow channel is provided in the middle of the heat conductive block 705, and an opening on one side of the air flow channel in the middle of the heat conductive block 705 is interconnected with the first diverter groove 7010, and an opening on the other side of the air flow channel in the middle of the heat conductive block 705 is interconnected with the second diverter groove 7011 on the heat insulating column 704, one end of the heat dissipating fin 701 close to the heat insulating column 704 is in contact with the heat insulating column 704, and the heat insulating column 704 can rotate on the center tube 706, and the center tube 706 is interconnected with the air flow channel in the middle of the heat conductive block 705, the angle between the first diverter groove 7010 and the second diverter groove 7011 on the heat insulating column 704 is 90°, and the outer wall of the heat insulating column 704 and the inner wall of the lower mold 1 are in contact with each other.

[0031] When aluminum alloy casting is required, the heat insulating column 704 is rotated. After the heat insulating column 704 is rotated, it can drive the heat conductive block 705 thereon to rotate synchronously, so that the heat conductive block 705 and the heat dissipation fins 701 inside the lower mold 1 are mutually offset, thereby isolating the heat dissipation of the heat dissipation fins 701 to the outside, slowing down the heat dissipation effect of the lower mold 1 when injecting liquid, and the upper mold 2 is covered on the lower mold 1. After the upper mold 2 is covered, it can pressurize the contact rod 603, so that the contact rod 603 and the adjustment plate 601 moves downward, and the adjustment plate 601 can drive the ejecting block 604 to move synchronously after moving downward, and inject liquid into the fluid channel 5, and the liquid flows into the mold cavity 3. When the fluid injection is completed and the mold needs to be cooled, the heat insulating column 704 is rotated in the opposite direction. After the heat insulating column 704 rotates, the heat conducting block 705 on it can overlap with the heat dissipating fin 701 again. At this time, the heat dissipating fin 701 can transfer heat to the heat conducting block 705. 5 is in contact with the outside air for normal heat dissipation. After the heat conducting block 705 and the heat dissipation fins 701 are aligned with each other, the first flow divider groove 7010 on the heat conducting block 705 and the flow guide groove 702 on the heat dissipation fins 701 are aligned with each other. At this time, the air pump 709 supplies air to the inside of the central tube 706. After the air is supplied to the inside of the central tube 706, the air flow can enter the inside of the heat conducting block 705. After the air flow enters the heat conducting block 705, the air flow can pass through the first flow divider groove 7010 and the flow guide groove 702. After entering the interior of the heat dissipation fin 701, the air flow absorbs the heat of the heat dissipation fin 701 and is discharged outward through the air outlet duct 703, thereby improving the cooling effect of the lower mold 1. After the lower mold 1 has cooled down, the upper mold 2 is opened. After the upper mold 2 and the lower mold 1 are opened, the resistance rod 603, the adjustment plate 601 and the ejection block 604 are reset and rebounded under the action of the first spring 602. The reset ejection block 604 ejects the molded casting in the mold cavity 3 outward, thereby improving the overall demolding efficiency.

[0032] Embodiment 2: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiment 1. The following technical content is disclosed in this embodiment: a knocking component 8 is arranged below the movable heat dissipation component 7, and the knocking component 8 is installed on the side of the lower mold 1 to reduce the bubbles in the fluid, the knocking component 8 includes a limit cover 801, and the upper end of the limit cover 801 is provided with an air inlet hole 802, the lower end of the limit cover 801 is provided with an exhaust hole 803, a piston plate 804 is installed inside the limit cover 801, and the piston plate 804 is connected to the limit cover 801 through a second spring 805, and the side of the piston plate 804 is provided with a A vibration rod 806 is provided, and a power magnetic block 807 is installed on one end of the vibration rod 806 close to the piston plate 804 and on the piston plate 804. The vibration rod 806 is connected to the lower mold 1 through a third spring 808. The power magnetic block 807 at the end of the vibration rod 806 and the power magnetic block 807 on the piston plate 804 have opposite magnetic properties. The power magnetic block 807 at the end of the vibration rod 806 and the power magnetic block 807 on the piston plate 804 correspond to each other one by one. The diameter of the air inlet hole 802 at the upper end of the limit cover 801 is larger than the diameter of the exhaust hole 803 at the lower end, and the air inlet hole 802 and the exhaust hole 803 are both arranged on the side of the limit cover 801 close to the lower mold 1.

[0033] When liquid is injected into the interior of the mold core 4 through the fluid channel 5, the heat insulating column 704 is rotated. After the heat insulating column 704 is rotated, the heat conductive block 705 and the heat dissipation fin 701 can be mutually offset. After the heat insulating column 704 and the heat conductive block 705 are rotated, the first diverter groove 7010 and the diverter groove 702 on the heat dissipation fin 701 can be mutually offset, and the lower end opening of the second diverter groove 7011 is aligned with the air inlet hole 802 on the limit cover 801. The pump 709 introduces air into the center tube 706. The air in the center tube 706 passes through the heat conducting block 705, the second flow dividing groove 7011 and the air inlet hole 802 and enters the interior of the limit cover 801. Since the diameter of the air inlet hole 802 is larger than the diameter of the exhaust hole 803, when air is injected into the limit cover 801, although part of the air flows out, it will also increase the air flow inside the limit cover 801, thereby pushing the piston plate 804 to enter the interior of the limit cover 801. The piston plate 804 moves, and after the piston plate 804 moves, the powered magnetic block 807 and the powered magnetic block 807 on the vibration rod 806 move away from each other, and the vibration rod 806 is reset and rebounded by the third spring 808. The reset vibration rod 806 hits the lower mold 1, and the vibration generated by the impact of the vibration rod 806 on the lower mold 1 can break the bubbles in the mold cavity 3. At the same time, when the vibration rod 806 needs to move back and forth continuously, after the vibration rod 806 hits once, the air pump 709 stops supplying air, and the air flow inside the limit cover 801 is discharged outward through the exhaust hole 803, and the piston plate 804 is reset under the action of the second spring 805. After the piston plate 804 is reset, the powered magnetic block 807 on it is close to the powered magnetic block 807 on the vibration rod 806 again, and the magnetic attraction is used to make the vibration rod 806 move away from the lower mold 1. Thereafter, the air pump 709 continues to supply air to achieve the impact of the vibration rod 806 again, and this reciprocating cycle is repeated.
