[0002] A die-casting mold is a tool for casting metal parts. It is a tool that completes the die-casting process on a dedicated die-casting forging machine. In order to eliminate bubbles in the molten metal, some factories use vacuum die-casting. However, vacuum die-casting will increase production costs and has higher requirements for molds and metal materials. Centrifugal and vibration methods are also used to defoam in the existing technology.

[0003] In the invention with publication number CN117259720A, a vibration mechanism is set up. After the upper mold frame is installed, the drive motor is started to drive the eccentric rotating block to rotate to generate uneven vibration force, so that the upper mold frame has slight vibrations that are transmitted to the metal liquid in the lower mold frame, so that the bubbles in the metal liquid can be discharged upward at a faster speed under the action of external force.

[0004] In the above invention, bubbles are vibrated to the upper surface of the metal liquid only by vibration.

[0048] In another embodiment provided by the present invention, the heat dissipation mechanism 10 includes a lifting groove 101 opened on two opposite sides of the upper end of the upper module 5, and a guide groove 4 102 is opened on the inner wall of the upper end of the lifting groove 101, a guide groove 5 103 is connected between one end of the lifting groove 101 and the conduit 1 6, and the other end of the lifting groove 101 is connected to the conduit 2 7, a lifting block 104 is provided on the upper end of the lifting groove 101 for sliding up and down, and a spring 4 107 is fixed between the upper end of the lifting block 104 and the upper module 5, and the lifting block 104 is fixed to the upper module 5.

[0049] The first slot 105 is longer than the second slot 106 .

[0050] Specifically, when the upper module 5 moves upward, the vacuum pump 3 sucks air, and the guide groove 6 1010 is connected with the guide groove 4 102. At this time, the cylinder 2 is closed, and the vacuum pump 3 sucks air out of the outer side of the upper module 5 to quickly dissipate the heat of the metal.

[0051] In another embodiment provided by the present invention, the anti-extrusion mechanism 11 includes an airbag 111 arranged on two opposite sides of the bottom end of the placing table 1, and an air storage cavity 113 is opened in the placing table 1 on the side of the airbag 111 away from the lower mold 4, and a connecting hose 112 is connected between the air storage cavity 113 and the airbag 111, a slider 114 is movably arranged at the upper end of the air storage cavity 113, and an isolation cavity is provided in the air storage cavity 113, a slider 2 115 is movably arranged in the isolation cavity, the isolation cavity is connected to the conduit 2 7, a pull rope 2 116 is connected between the bottom end of the slider 2 115 and the slider 1 14, and a spring 6 119 is fixedly connected between the upper end of the slider 114 and the placing table 1.

[0052] One end of the airbag 111 away from the air storage chamber 113 abuts against a sliding plate 122, and a sleeve block 121 is movably sleeved on the outer side of the sliding plate 122, and a connecting block 123 is fixedly connected to a side wall of the sliding plate 122 away from the airbag 111, and a liquid storage chamber 124 is opened on the sleeve block 121, and a non-Newtonian fluid is arranged in the liquid storage chamber 124, and the other end of the connecting block 123 is movably inserted in the liquid storage chamber 124, and a lifting plate 128 is slidably arranged in the connecting block 123, and the top of the lifting plate 128 is fixedly connected to the connecting block 123. There is a spring seven 127, and a limit rod 125 is horizontally slidably provided on the lower surface of the lifting plate 128, and the bottom end of the limit rod 125 is movably inserted in the placement table 1, and a contact rod 126 is fixedly connected to the inner wall of the sleeve block 121, and the other end of the contact rod 126 abuts against the upper end of the limit rod 125, and a side wall of the sleeve block 121 away from the airbag 111 is fixedly connected to an extrusion block 117, and a spring five 118 is fixedly connected between the side wall of the bottom end of the extrusion block 117 and the placement table 1, and the end of the extrusion block 117 away from the sleeve block 121 abuts against the bottom end of the trapezoidal plate 8.

[0053] The liquid storage chamber 124 is not filled with the non-Newtonian fluid, and the air pressure in the liquid storage chamber 124 is lower than the standard atmospheric pressure.

[0054] Specifically, the non-Newtonian fluid is not filled and the air pressure in the liquid storage chamber 124 is low, which prevents the connection block 123 from sliding in the liquid storage chamber 124 .

[0055] When the upper module 5 moves upward, the vacuum pump 3 performs air suction, which can quickly fill the airbag 111 with gas to prevent squeeze marks. On this basis, if the metal cools too quickly, it can be demoulded in time.

[0056] Working principle: When in use, first pour the metal liquid into the inner cavity of the lower mold 4, then start the cylinder 2, and the upper module 5 moves downward. When the end of the slide plate 912 extending to the outside of the upper module 5 just touches the inner wall of the upper end of the lower mold 4, the gas in the inner cavity of the lower mold 4 is connected with the gas on the upper side through the ventilation groove 99. When the upper module 5 continues to move downward, the slide plate 912 is compressed inward. When the ventilation groove 99 is completely retracted into the upper module 5, the inner cavity of the lower mold 4 is in a closed state. Start the vacuum pump 3 and turn off the cylinder 2. At this time, the upper module 5 is located on the upper side of the metal liquid, the pressing plate 91 will be away from the upper end of the lifting column 92, and the pressing plate 9 1 will be squeezed by the squeezing block 2 96, the pressing plate 91 will slide toward the side of the magnetic block 1 95, the magnetic block 1 95 will adsorb the iron block 910, and then the lifting column 92 can be sucked upward by the vacuum pump 3, so that the lifting column 92 moves upward, which can quickly reduce the air pressure on the upper side of the metal liquid, and the pressure of the gas in the bubble is greater than that on the outside, so that the bubble can be quickly broken, thereby improving the work efficiency. There is no need to use a vacuum device to evacuate the gas in the entire lower mold 4, and only the pressure in some areas needs to be reduced. The production cost is low, and compared with other devices that simply rely on knocking to break the bubble, the effect is better and faster;

[0057] When the lower pressing block 915 moves upward, each trapezoidal extrusion rod 98 will be squeezed inward in turn. When the trapezoidal extrusion rod 98 is squeezed inward, the lower pressing block 915 will be squeezed downward. When the corresponding trapezoidal extrusion rod 98 moves upward to the sliding cavity 916, due to the suction force of the second magnetic block 913 on the lower pressing block 915, the lower pressing block 915 moves upward, and the trapezoidal extrusion rod 98 extends into the sliding cavity 916. When each trapezoidal extrusion rod 98 stretches back and forth, the lower pressing block 915 moves up and down. Therefore, when the lifting column 92 moves upward to rapidly reduce the pressure in the inner cavity of the lower mold 4, the lower pressing block 915 moves up and down, which can make the pressure in the inner cavity of the lower mold 4 fluctuate, so that the shape of the bubble changes back and forth, and the bursting speed of the bubble is further improved.

[0058] Each time the lower pressing block 915 moves downward, the fixed column 914 will be located at the upper side, the guide groove 1 917 can be connected to the inner cavity of the lower mold 4, and the gas in the sliding cavity 916 will be pressed out from the guide groove 1 917, and the gas in the sliding cavity 916 will be sprayed out from the center of the bottom end of the lower pressing block 915, so that the bubbles on the upper surface of the metal liquid can be sprayed to the surrounding side, so that the bubbles will not gather together, the stability of the bubbles can be reduced, and the bursting speed of the bubbles can be further accelerated;

[0059] When the bubble bursts, the upper module 5 continues to move downward. At this time, the lower surface of the lifting column 92 is flush with the lower surface of the upper module 5, and the insertion rod 920 is squeezed by the fixing rod 919, so that the guide groove 3 923 and the guide groove 2 922 are connected, so that the inner cavity of the lower mold 4 is reconnected with the outside to prevent the gas from being pressed into the metal liquid in the closed state. Then, the upper module 5 presses down to die-cast the metal liquid. After the die-casting is completed, the upper module 5 moves up, and the pressure plate 91 is reset by the spring 2 918. 1 will squeeze the inclined sliding surface 97, so that the lifting column 92 will be pressed downward. When the pressing plate 91 moves to the original position, the squeezing block 1 93 will squeeze the trapezoidal connecting rod 94, so that the magnetic block 1 95 and the iron block 910 are separated. Under the action of the spring 1 911, the iron block 910 and the pressing plate 91 are pulled to the other side for the next use. This arrangement is to enable the lifting column 92 to move upward instantly when the pressing plate 91 is separated from the top of the lifting column 92, and when it is reset, the movement of the pressing plate 91 is not delayed;

[0060] When the pressing plate 91 is reset, the sliding plate 912 will squeeze the plug plate 109 outward, and the lifting block 104 will move downward through the transmission of the pull rope 108. When the lifting block 104 moves downward, the notch 2 106 and the notch 1 105 will instantly connect the conduit 2 7 and the guide groove 5 103, so that the suction of the vacuum pump 3 will instantly suck the slider 2 115 upward through the conduit 2 7, so the slider 114 moves downward, and the downward movement of the slider 114 will cause the gas in the air storage chamber 113 to be instantly squeezed into the air bag 111, and then the air bag 111 can slowly squeeze the trapezoidal plate 8 through the squeezing block 117. When it is completely cooled, the demolding gap between the metal and the lower mold 4 is fully formed, and then the metal will automatically move upward and detach from the lower mold 4 to prevent squeezing marks and When the gas in the gas storage chamber 113 is squeezed into the airbag 111 instantly, the impact force of the airbag 111 is too large. At this time, the connecting block 123 will quickly squeeze the non-Newtonian fluid in the liquid storage chamber 124, and the non-Newtonian fluid will harden. The connecting block 123 can no longer move in the sleeve block 121, so that the limiting rod 125 cannot be separated from the placement table 1, and the sleeve block 121 and the squeezing block 117 will be limited. When the speed of the airbag 111 slows down, the connecting block 123 moves inward, the contact rod 126 squeezes the limiting rod 125 upward, and the squeezing block 117 can slowly squeeze the metal upward, so that the airbag 111 can be quickly filled with gas. If the metal cools too quickly, it can be demoulded in time, and on this basis, it can prevent the airbag 111 from expanding too quickly and causing too much impact on the metal.

[0061] When the lifting block 104 continues to move downward, the guide groove six 1010 is connected to the guide groove four 102. At this time, the cylinder 2 is closed, and the vacuum pump 3 can suck out the gas on the outside of the upper module 5, and the hot air in the lower mold 4 is discharged outward through the ventilation groove 99. After the heat dissipation is completed, the vacuum pump 3 is closed, the cylinder 2 is started, and the upper module 5 continues to move upward. When the lifting block 104 is reset upward, the gas in the pipeline will enter the isolation cavity where the slider two 115 is located, so that the airbag 111 will recover to prevent it from remaining in an expanded state and reducing the service life of the airbag 111.

[0062] It should be noted that the device can be used in conjunction with a vibration component in the prior art to accelerate the floating of bubbles.
