[0002] With the continuous development of the construction industry and the improvement of people's quality of life, aluminum alloy railings have been widely used in architectural decoration, garden landscape, municipal engineering and other fields. Aluminum alloy railings have the advantages of light weight, corrosion resistance, high strength and beautiful appearance, making them an ideal choice to replace traditional iron railings and stainless steel railings.
[0003] At present, there is a die-casting forming device for the production of aluminum alloy railings. After the movable mold and the fixed mold are clamped for die-casting, the molten aluminum alloy is injected into the movable mold cavity to form an aluminum alloy railing profile.

The die-casting device for the production of aluminum alloy railings uses a hydraulic cylinder and a hydraulic telescopic rod to move the movable mold to the surface of the fixed mold for clamping, and the opened gate injects the molten aluminum alloy into the movable mold cavity to form an aluminum alloy railing semi-finished product. The air pump is started to lead the high-pressure gas generated in the movable mold cavity through the exhaust groove and suck it into the cooling pipe.

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.
[0020] See also Figure 1 , Figure 5 and Fig. 9As shown, the purpose of this embodiment is to provide a die-casting molding device for the production of aluminum alloy railings, including a driving mechanism 100, a heat conduction mechanism 200 and a demoulding cooling mechanism 300, the heat conduction mechanism 200 is arranged on the upper surface of the driving mechanism 100, the demoulding cooling mechanism 300 is installed on one side of the surface of the heat conduction mechanism 200, the driving mechanism 100 includes a movable mold 105 and a fixed mold 108, the movable mold 105 surface is provided with a movable mold cavity 113, the fixed mold 108 surface center position is provided with a gate 109, the heat conduction mechanism 200 includes an exhaust groove 201, the exhaust groove 201 is provided on the movable mold On both sides of the surface of the mold 105, one side of the exhaust groove 201 is sleeved with an exhaust pipe 202, and one side of the exhaust pipe 202 is sleeved with a cooling pipe 203. The demoulding cooling mechanism 300 includes an air guide pipe 301, and both sides of the surface of the air guide pipe 301 are connected with an air pump 302. One side of the exhaust pipe 202 is correspondingly connected to one side of the air guide pipe 301 through the air pump 302. The back of the air guide pipe 301 is connected with an air delivery pipe 303, and one side of the surface of the air delivery pipe 303 is telescopically sleeved with a telescopic pipe 305. One side of the surface of the telescopic pipe 305 is fixedly connected with a push plate 304, and the surface of the push plate 304 is clamped on the surface of the movable mold cavity 113; The movable mold 105 is slidably connected to one side of the surface of the fixed mold 108, and the molten aluminum alloy is injected into the movable mold cavity 113 through the gate 109, and the aluminum alloy railing is die-cast in the movable mold cavity 113. In the process of die-casting the aluminum alloy railing profile, the high-pressure gas generated is discharged through the exhaust groove 201, and the air pump 302 is operated to suck the high-pressure gas into the exhaust pipe 202, and the high-pressure gas is cooled in the cooling pipe 203 and circulated in the air guide pipe 301 and the air delivery pipe 303. And under the impact effect of gas flowing in the gas pipe 303, the telescopic tube 305 is extended on one side of the surface of the gas pipe 303. At the same time, under the action of thrust, the push plate 304 is pushed synchronously, so that the push plate 304 extends out of the surface of the movable mold cavity 113, which can generate thrust for the aluminum alloy railing die-cast in the movable mold cavity 113 and push it out of the movable mold cavity 113. At the same time, the air flow is discharged from the air outlet grooves 306 opened around the surface of the push plate 304, and dispersed to the back surface of the aluminum alloy railing, which has the effect of rapid cooling.
[0021] Therefore, based on the above structure, combined with Figure 1-Figure 4As shown, the structure of the driving mechanism 100 is further disclosed. The driving mechanism 100 includes a workbench 101, a hydraulic cylinder 102 is installed on the left side of the upper surface of the workbench 101, a hydraulic telescopic rod 103 is connected to the right side of the surface of the hydraulic cylinder 102, a slide plate 104 is connected to the right side of the surface of the hydraulic telescopic rod 103, a movable mold 105 is installed on the right side of the surface of the slide plate 104, a screw rod 106 is slidably sleeved around the surface of the slide plate 104, a fixed plate 107 is installed on the right side of the surface of the screw rod 106, a fixed mold 108 is installed on the left side of the surface of the fixed plate 107, a gate 109 is opened at the center of the surface of the fixed plate 107, a clamping plate 111 is installed on both sides of the inside of the fixed mold 108, a through hole 112 is opened on one side of the surface of the clamping plate 111, and a clamping groove 110 is opened on the upper surface of the fixed mold 108; Furthermore, by starting the hydraulic cylinder 102, the hydraulic telescopic rod 103 pushes the slide plate 104 to slide on the surface of the screw rod 106, and synchronously allows the movable mold 105 to slide toward the surface of the fixed mold 108. After the movable mold 105 and the fixed mold 108 are clamped and die-cast, the provided clamping groove 110 can be clamped to the air guide pipe 301 installed on the upper surface of the movable mold 105. At the same time, the clamping plate 111 can clamp and clamp both sides of the surface of the cooling pipe 203. The exhaust pipe 202 and the exhaust groove 201 are connected to each other by the through hole 112, so as to ensure that the high-pressure gas generated in the movable mold cavity 113 is extracted; The improvement lies in that the clamping plate 111 can protect the surface of the cooling pipe 203, thereby preventing the high-pressure gas in the movable mold cavity 113 from being transmitted from the exhaust groove 201 to the outer surface of the cooling pipe 203, and also preventing the high-pressure gas from being extracted from the movable mold cavity 113 in an unsatisfactory manner, wandering around the movable mold cavity 113, and causing damage to the cooling pipe 203, the mold and the surface of the aluminum alloy railing.
[0022] Based on the above structure, combined with Figure 5-Figure 6 As shown, the structure of the heat conduction mechanism 200 is further disclosed, the exhaust grooves 201 are provided on both sides of the surface of the movable mold 105, a cooling pipe 203 is installed on one side of the surface of the exhaust groove 201, a cooling blade 204 is movably installed inside the cooling pipe 203, and an exhaust pipe 202 is sleeved on one side of the surface of the cooling pipe 203; Furthermore, the high-pressure gas generated by die-casting in the movable mold cavity 113 is discharged through the exhaust groove 201, and the exhaust pipe 202 sucks the high-pressure gas into the cooling pipe 203. The air pump 302 operates, and the suction force generated allows the high-pressure gas to flow from bottom to top in the cooling pipe 203. Under the effect of the high-pressure gas flow, the cooling blades 204 rotate inside the cooling pipe 203, so that the high-pressure gas flows from the inside of the cooling pipe 203 to the inside of the air guide pipe 301; The improvement lies in: utilizing the suction force generated by the operation of the air pump 302 to suck out the high-pressure gas inside the movable mold cavity 113, and then sucking the high-pressure gas into the cooling pipe 203 through the exhaust pipe 202. By virtue of the effect of the high-pressure gas flowing from bottom to top in the cooling pipe 203, the cooling blades 204 rotate in the cooling pipe 203, thereby guiding and cooling the high-pressure gas, which is finally transmitted to the air guide pipe 301 for subsequent reuse of the cooled gas.
[0023] Based on the above structure, combined with Figure 7-Figure 8 As shown, the structure of the demoulding cooling mechanism 300 is further disclosed, the upper surface of the cooling tube 203 is sleeved with an air guide tube 301, the back surface of the air guide tube 301 is connected to an air delivery tube 303, one side of the surface of the air delivery tube 303 penetrates the inside of the movable mold 105, one side of the surface of the air delivery tube 303 is movably sleeved with a telescopic tube 305, one side of the surface of the telescopic tube 305 is connected to a push plate 304, and the surface of the push plate 304 is provided with air outlet grooves 306 around the periphery; Furthermore, the cooled gas is transmitted to the air guide pipe 301 and then to the air delivery pipe 303 in an orderly manner. When the gas is transmitted to one end of the inner side of the air delivery pipe 303, the telescopic pipe 305 is extended on one side of the surface of the air delivery pipe 303 under the impact of the gas flow, and a thrust is generated on the push plate 304, so that the push plate 304 is extended on the surface of the movable mold cavity 113, and the aluminum alloy railing in the movable mold cavity 113 is pushed, so that the aluminum alloy railing is separated from the surface of the movable mold cavity 113, and the air flow can be ejected from the air outlet grooves 306 opened around the surface of the push plate 304; The improvement lies in that: by utilizing the gas flowing in the gas pipe 303 and the impact force generated by the gas flow, the telescopic tube 305 is extended on one side of the surface of the gas pipe 303, and then the push plate 304 is pushed out from one side of the surface of the dynamic mold cavity 113, and the aluminum alloy railing in the dynamic mold cavity 113 is pushed out by the push plate 304 to achieve the separation effect. At the same time, the air outlet grooves 306 opened around the surface of the push plate 304 are correspondingly connected to the surface of the dynamic mold cavity 113, and the gas can cool the back surface of the aluminum alloy railing. Compared with pushing the ejector pin out through the hydraulic telescopic rod 103 and ejecting the aluminum alloy railing from the dynamic mold cavity 113 by the ejector pin, the aluminum alloy railing can be more completely separated from the dynamic mold cavity 113 during the ejection process of the aluminum alloy railing. In addition, in the separation process, the use of three groups of push plates 304 can also reduce the damage to the surface of the aluminum alloy railing, so that the separation and drying of the aluminum alloy railing can be carried out simultaneously, and the effect is more significant.
[0024] In summary, the working principle of this scheme is as follows: the movable mold 105 uses the hydraulic cylinder 102 and the hydraulic telescopic rod 103 to move and clamp to the surface of the fixed mold 108, and the opened gate 109 injects the molten aluminum alloy into the movable mold cavity 113 to form an aluminum alloy railing semi-finished product, and the air pump 302 is started to lead the high-pressure gas generated in the movable mold cavity 113 through the exhaust groove 201 and suck it into the cooling pipe 203. Under the effect of the rapid circulation of high-pressure gas, the cooling blade 204 rotates inside the cooling pipe 203 to dissipate the high-pressure gas, and finally transmits it to the air guide pipe 301 to suck the high-pressure gas out of the movable mold cavity 113, which helps the mold to dissipate heat better, reduce the risk of thermal fatigue, and extend the service life of the mold. At the same time, the high-pressure gas is sucked out to reduce the pore defects, which can improve the mechanical properties of the product and make it more durable. After the high-pressure gas is sucked out from the dynamic mold cavity 113, the high-pressure gas is cooled by the cooling blades 204 and then transmitted from the cooling pipe 203 to the air guide pipe 301. The cooled high-pressure gas is transmitted to the air delivery pipe 303 by the air pump 302. The generated airflow causes the telescopic tube 305 to extend out of one side of the surface of the air delivery pipe 303, and causes the push plate 304 to extend out of one side of the surface of the dynamic mold cavity 113. At the same time, the air outlet grooves 306 opened around the surface of the push plate 304 eject the cooled high-pressure gas, so that the aluminum alloy railing die-cast in the dynamic mold 105 is cooled, and then the aluminum alloy railing is pushed out from the surface of the dynamic mold 105. The cooled high-pressure gas is used to cool the back of the aluminum alloy railing by the air outlet grooves 306.
