Abstract
Description
Technical Field
[0001] The present application relates to the technical field of aluminum alloy die-casting molds, and in particular to a cooling and ejection device for an aluminum alloy die-casting mold. Background Art
[0002] In the aluminum alloy die casting production process, the cooling efficiency and uniformity of the mold have a crucial impact on the quality of the casting and the production cycle. Traditional cooling methods are usually limited to external cooling or internal cooling, which makes it difficult to achieve a comprehensive and uniform cooling effect, which often leads to the following problems:
[0003] Traditional cooling systems usually require manual intervention, which increases the complexity and labor intensity of the operation, and is also prone to poor cooling effects due to human factors;
[0004] Traditional cooling systems can usually only cool a certain part of the mold, resulting in uneven temperature distribution on the mold surface, which in turn causes thermal stress inside the casting, which may eventually lead to defects such as shrinkage and deformation.
[0005] Traditional cooling systems often lack designs that are coordinated with the demoulding process, which makes the operation of pushing the casting out after it is formed complicated and inconvenient. The cooling system and the pushing device are usually designed separately and lack an effective linkage mechanism. It is difficult to achieve automated casting pushing operations while cooling, resulting in the entire production process being not smooth enough. Summary of the invention
[0006] The present application aims to at least solve the problem that the traditional cooling system in the prior art often lacks a design coordinated with the demolding process, which makes the operation of pushing the casting after it is formed complicated and inconvenient. The cooling system and the pushing device are usually designed separately and lack an effective linkage mechanism. It is difficult to realize automated casting pushing operation while cooling, which leads to one of the problems that the entire production process is not smooth enough. For this reason, the present application proposes a cooling and pushing device for an aluminum alloy die-casting mold.
[0007] To achieve the above-mentioned purpose, the present invention provides a cooling and ejection device for an aluminum alloy die-casting mold, comprising an upper mold and a lower mold, wherein a fixing frame is fixedly provided on one side of the upper mold, a cylinder is installed at one end of the fixing frame, and the piston end of the cylinder is fixedly connected to one side of the lower mold, and a cooling component 1 is installed on one side of the lower mold, and the cooling component 1 extends to the inner side of the lower mold, and a movable groove is opened on the fixing frame, and a cooling component 2 is slidably installed in the movable groove, and the cooling component 2 semi-wraps the lower mold.
[0008] Furthermore, the second cooling component includes a moving block sliding in a moving groove, a pair of brackets are fixedly arranged on the upper side of the moving block, a spray piece is installed in the bracket, the spray piece sprays the outer side of the lower mold, the water inlet end of the spray piece is connected to the water outlet end on one side of the diversion pipe through a pipe, the water inlet end of the diversion pipe is connected to the water outlet end of the water pump, and the water inlet end of the water pump is connected to the water outlet end of the cold water tank through a pipe.
[0009] Furthermore, a limiting rod is fixedly arranged in the movable groove, the movable block is slidably matched with the limiting rod, an elastic member 1 is sleeved on the limiting rod, and one end of the elastic member 1 is fitted with one side of the movable block.
[0010] Furthermore, a buffer pad is provided at one end of the movable groove.
[0011] Furthermore, a push plate is provided on one side of the lower mold, and an insert block is provided on one side of the push plate, and the insert block is plugged and matched with a plug hole provided on one side of the bracket.
[0012] Furthermore, the cooling component includes a pair of guide rods passing through the lower mold, one end of the guide rod is fixedly connected to a horizontal plate, a round tube is installed on the inner side of the horizontal plate, a plurality of hollow rods are arranged on one side of the round tube, the hollow rods slide into a model groove opened on the inner side of the lower mold, a plurality of water outlet holes are opened at the end of the hollow rods, the water inlet end of the round tube is connected to the water outlet end of the long tube through a hose, and the water inlet end of the long tube is connected to the other water outlet end of the diversion tube through a pipe.
[0013] Furthermore, valve one and valve two are respectively installed at the two water outlet ends of the diversion pipe.
[0014] Furthermore, a second elastic member is connected between the transverse plate and the lower mold.

The positioning rod 1 and the positioning rod 2 are respectively plugged into the positioning hole 1 and the positioning hole 2.
[0017] The beneficial effect of the present application is that when the lower mold and the upper mold are closed, the water pump draws the cold water in the cooling box into the spray part. The spray part then sprays and cools the outside of the mold, ensuring that the surface temperature of the mold drops rapidly, improving the quality of the casting and shortening the production cycle. When the cylinder drives the lower mold to move back, the push plate pushes the bracket to make the moving block slide along the moving groove. This design enables the spray part to move synchronously with the lower mold and continuously cool the outside of the mold, ensuring the continuity and uniformity of the cooling process. When the lower mold moves back to a specific position, the ejector pushes the cross plate to cause the hollow rod to eject the formed casting from the model groove. At the same time, cold water enters the hollow rod and sprays out through the water outlet holes on it to cool the inside of the lower mold. This internal cooling method effectively reduces the temperature inside the mold, further improving the cooling efficiency and casting quality. By combining external spray cooling with internal ejector cooling, not only comprehensive cooling of the inside and outside of the mold is achieved, but also the cooling speed and uniformity are significantly improved, the thermal stress caused by temperature difference is reduced, and possible defects in castings are prevented. In addition, this design simplifies the operating process and improves overall production efficiency.

[0041] A cooling and ejection device for an aluminum alloy die-casting mold according to an embodiment of the present application is described below with reference to the accompanying drawings.
[0042] like Figure 1-Figure 11As shown, a cooling and ejection device for an aluminum alloy die-casting mold according to an embodiment of the present application includes an upper mold 1 and a lower mold 2. In order to ensure the stability and reliability of the entire mold system during use, a fixing frame 3 is fixedly arranged on one side of the upper mold 1. The fixing frame 3 can be fixed at a specific position in the equipment or factory for use, so that the entire mold is more stable during use. The fixing frame 3 is made of high-strength material and has sufficient rigidity and strength to withstand various stresses and vibrations generated during high-pressure casting. Its design fully considers the load requirements under different working conditions to ensure that the mold remains stable during long-term operation.
[0043] In addition, a cylinder 12 is installed at one end of the fixed frame 3, and the piston end of the cylinder 12 is fixedly connected to one side of the lower mold 2. The closing and opening of the lower mold 2 and the upper mold 1 can be achieved by the contraction of the cylinder 12. Specifically, when the mold needs to be closed, the piston rod of the cylinder 12 extends to push the lower mold 2 to move until it is tightly fitted with the upper mold 1. At this time, a closed cavity is formed inside the mold, ready to receive the injection of molten metal. After the casting is completed, the piston rod of the cylinder 12 contracts, driving the lower mold 2 to move back to achieve the mold opening operation. During this process, the smooth power provided by the cylinder 12 ensures the smooth separation of the lower mold 2, while reducing damage to the surface of the casting.
[0044] In order to ensure that the upper and lower molds can be accurately aligned and maintain the same relative position when the molds are closed, two positioning rods are fixedly installed on the inner side of the upper mold 1: positioning rod 1 8 and positioning rod 2 9. These two positioning rods are usually processed with high precision to ensure their accurate size and smooth surface, so as to achieve gapless insertion. At the same time, two positioning holes are opened at the corresponding positions on the inner side of the lower mold 2: positioning hole 10 and positioning hole 2 11. The design of these positioning holes also requires high-precision processing to ensure close fit with the positioning rods. When the upper mold 1 moves downward for mold closing, the positioning rod 1 8 is first inserted into the positioning hole 10 in the lower mold 2. This process not only provides a preliminary positioning reference, but also ensures the precise alignment of the upper and lower molds in the X-axis and Y-axis directions. Then, the positioning rod 2 9 is inserted into the positioning hole 2 11, which further enhances the alignment accuracy between the upper and lower molds and provides additional stability in the Z-axis direction to prevent the mold from shifting or misaligning.
[0045] In order to cool the mold, a cooling component 1 is installed on one side of the lower mold 2, and the cooling component 1 extends to the inner side of the lower mold 2. A movable groove 4 is opened on the fixed frame 3, and a cooling component 2 is slidably installed in the movable groove 4. The cooling component 2 semi-wraps the lower mold 2 to provide a wide coverage range to ensure the comprehensiveness and uniformity of the cooling effect. By combining external spray cooling with internal push cooling, not only comprehensive cooling of the inside and outside of the mold is achieved, but also the cooling speed and uniformity are significantly improved, the thermal stress caused by temperature difference is reduced, and possible defects of the casting are prevented.
[0046] Specifically, cooling component 2 is provided with a moving block 30 sliding in the moving groove 4, and a pair of brackets 28 are fixedly provided on the upper side of the moving block 30. A spray piece 29 is installed in each bracket 28. The spray piece 29 is composed of high-quality steel pipes and efficient atomizing nozzles. The design of the atomizing nozzle ensures that the cooling water can be evenly sprayed on the mold surface in the form of fine droplets, thereby achieving a fast and effective cooling effect. The water inlets of the two groups of spray pieces 29 are connected in series through pipes, which can ensure that the water flow is evenly distributed to each nozzle, thereby ensuring the consistency and stability of the cooling process.
[0047] The water inlet end of the spray piece 29 is connected to the water outlet end on one side of the shunt pipe 24 through a pipeline, the water inlet end of the shunt pipe 24 is connected to the water outlet end of the water pump 27, the water inlet end of the water pump 27 is connected to the water outlet end of the cold water tank 31 through a pipeline, and the cold water tank 31 is located at one end of the fixed frame 3. Through the above design, the water pump 27 draws the cold water in the cold water tank 31 and transports it to the spray piece 29 through a pipeline, and finally sprays it on the outside of the lower mold 2 through an atomizing nozzle, thereby realizing effective cooling of the outer surface of the mold. This process can not only quickly reduce the mold temperature and improve production efficiency, but also effectively reduce the thermal stress caused by temperature difference, thereby improving the quality and consistency of the casting.
[0048] Furthermore, in order to ensure the continuity and uniformity of the cooling process, the present design sets a push plate 14 on one side of the lower mold 2, and a plug block 15 is installed on one side of the push plate 14, and a corresponding plug hole is provided on one side of the bracket 28. When the cylinder 12 drives the lower mold 2 to move back for mold opening operation, the plug block 15 is plugged into the plug hole, and the push plate 14 pushes the bracket 28, so that the moving block 30 slides in the moving groove 4. This design ensures that the spraying part 29 can follow the movement of the lower mold 2, continuously spray cooling the outer side of the mold, and ensures the continuity and uniformity of the cooling process.
[0049] like Fig. 9As shown, in order to enable the spraying member 29 to automatically reset and move stably, a limiting rod 5 is fixedly arranged in the moving groove 4, and the limiting rod 5 passes through the moving block 30, so that the moving block 30 and the limiting rod 5 are slidably matched, and an elastic member 6 is sleeved on the limiting rod 5, and one end of the elastic member 6 is in contact with one side of the moving block 30. When the lower mold 2 moves back through the cylinder 12 to open the mold, the push plate 14 pushes the bracket 28, and then pushes the moving block 30 to slide along the limiting rod 5. At this time, the moving block 30 squeezes the elastic member 6, and the elastic member 6 is deformed but still maintains a certain elastic force. When the cylinder 12 pushes the lower mold 2 to move toward the upper mold 1 again, the elastic member 6, due to its elastic characteristics, will prompt the moving block 30 to slide in the opposite direction along the limiting rod 5 and return to the initial position. In this way, the automatic reset of the spraying member 29 is realized, ensuring the efficient operation of the cooling system during each mold opening and closing process.
[0050] In addition, a buffer pad 7 is provided at one end of the movable groove 4. When the movable block 30 is reset to the end of the movable groove 4, the buffer pad 7 can effectively absorb the impact energy, prevent the movable block 30 from directly contacting the side wall of the movable groove 4, and avoid mechanical damage caused by collision. Through the buffering effect of the buffer pad 7, not only the movable block 30 and the movable groove 4 can be protected from damage, but also noise and vibration can be reduced, thereby extending the service life of the entire equipment.
[0051] like Figure 6 As shown, the cooling component 1 is provided with a pair of guide rods 18 passing through the lower mold 2, and the guide rods 18 are slidably matched with the lower mold 2. One end of the guide rod 18 is fixedly connected with a cross plate 17, and a round tube 19 is installed on the inner side of the cross plate 17. A plurality of hollow rods 20 are arranged on one side of the round tube 19. The hollow rods 20 slide into the model groove opened on the inner side of the lower mold 2. During the die-casting process, the ends of the hollow rods 20 are tightly sealed with the sliding holes in the model groove to prevent the liquid metal melt from overflowing, thereby ensuring the quality and precision of the casting. After the casting is formed, the cross plate 17 is pushed inward so that the hollow rods 20 can push out the formed casting, thereby simplifying the demoulding process and improving the production efficiency.
[0052] In addition, in order to further improve the cooling effect, a plurality of water outlet holes 21 are opened at the end of the hollow rod 20, and the water inlet end of the circular tube 19 is connected to the water outlet end of the long tube 23 through a hose 22, and the water inlet end of the long tube 23 is connected to the other water outlet end of the diversion tube 24 through a pipeline. The water supply of the entire cooling system is provided by a water pump 27. The cold water passes through the long tube 23, the circular tube 19 and the hollow rod 20 in turn, and is finally sprayed out from the water outlet hole 21 to cool the inner side of the lower mold 2. The hose 22 and the pipeline in this article have sufficient length for use.
[0053] like Figure 8As shown, valve one 25 and valve two 26 are respectively installed at the two water outlet ends of the diverter pipe 24. Valve one 25 and valve two 26 are precisely opened and closed according to the use requirements of cooling component one and cooling component two. Different casting types, sizes and production process requirements may have different cooling requirements. By precisely controlling the opening and closing of the valves, these changes can be quickly adapted to meet diverse production needs.
[0054] like Figure 7 As shown, a push rod 16 is fixedly installed at one end of the fixing frame 3 close to the lower mold 2, and the push rod 16 can pass through the through hole 13 opened on one side of the lower mold 2. When the cylinder 12 drives the lower mold 2 to move to the position of the push rod 16, as the lower mold 2 continues to move, the push rod 16 will push the cross plate 17. This action causes the cross plate 17 to slide into the mold with the round tube 19 and the hollow rod 20, thereby pushing the formed casting out of the mold.
[0055] In order to ensure that the cross plate 17 can automatically reset when not pushed by the ejector 16, an elastic member 2 32 is connected between the cross plate 17 and the lower mold 2. When the cross plate 17 is pushed by the ejector 16, the elastic member 2 32 will be stretched. Once the ejector 16 no longer applies thrust to the cross plate 17, the elastic action of the elastic member 2 32 will restore the cross plate 17 to its initial position, thus realizing the automatic reset function.
[0056] Working process: During casting, the spraying part 29 can be used to spray cool the outside of the mold. After casting is completed, the piston rod of the cylinder 12 contracts, driving the lower mold 2 to move downward to open the mold. When the lower mold 2 moves back, the plug block 15 on the push plate 14 cooperates with the plug hole of the bracket 28 to push the bracket 28, so that the moving block 30 slides along the limit rod 5, and the outside is continuously spray-cooled. At the same time, when the cylinder 12 drives the lower mold 2 to move to the position of the push rod 16, as the lower mold 2 continues to move, the push rod 16 will push the cross plate 17. This action causes the cross plate 17 to slide into the mold with the round tube 19 and the hollow rod 20, thereby pushing the formed casting out of the mold. At this time, if the valve 26 is opened, cold water can enter the long tube 23, the round tube 19 and the hollow rod 20, and finally spray out from the water outlet 21 to cool the inner side of the lower mold 2.
[0057] The above are only embodiments of the present application and are not intended to limit the scope of protection of the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.
[0058] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
