[0002] Die-casting machines can be divided into various types according to different structures and working principles, such as hot-chamber die-casting machines and cold-chamber die-casting machines. The latter can be further divided into vertical and horizontal types. This diverse classification not only meets the specific needs of different industries for metal forming technology but also reflects the high flexibility in the design and manufacturing of die-casting machines.

[0003] However, in actual use, there are still the following deficiencies.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1: As Figure 1 - Figure 3 shown, this embodiment provides a technical solution: a die-casting machine with a supercharging module, including a bracket 1. The top end of the bracket 1 is fixedly connected with a main supercharging component 2. The outside of the main supercharging component 2 is fixedly connected with an auxiliary supercharging component 3. The top end of the bracket 1 is fixedly connected with a supporting component 4. The top end of the bracket 1 is fixedly connected with a die-casting component 5;

[0036] The main supercharging component 2 includes a liquid delivery pipe 21. The outside of the liquid delivery pipe 21 is fixedly connected to the bracket 1. The outside of the liquid delivery pipe 21 is fixedly connected with a shunt pipe 22. The outside of the shunt pipe 22 is fixedly connected with a bifurcated pipe 23. A check valve 1 24 is installed on the inner wall of the bifurcated pipe 23. One end of the bifurcated pipe 23 away from the shunt pipe 22 is fixedly connected with a supercharging pipe 25. The top end of the supercharging pipe 25 is fixedly connected to the shunt pipe 22. A piston 26 is slidably connected to the inner wall of the supercharging pipe 25. The top end of the supercharging pipe 25 is fixedly connected with a cylinder 27. The driving end of the cylinder 27 is fixedly connected to the top end of the piston 26. A check valve 2 28 is installed on the inner wall of the shunt pipe 22. The liquid delivery pipe 21 is used to deliver liquid to various parts of the system, ensuring the stability and reliability during the delivery process. The shunt pipe 22 plays a role in liquid shunting, enabling the liquid to be evenly distributed to different working areas. The design of the bifurcated pipe 23 can further shunt the liquid. The check valve 1 24 only allows the liquid to flow in one direction, preventing the liquid from flowing back. The supercharging pipe 25 is used to transfer pressure during the supercharging process. Its top end is fixedly connected to the shunt pipe 22, ensuring a clear transfer path. The sliding movement of the piston 26 in the supercharging pipe 25 realizes the liquid supercharging function. The top end of the supercharging pipe 25 is fixedly connected with a cylinder 27. The cylinder 27 realizes supercharging by driving the movement of the piston 26. Its driving end is fixedly connected to the top end of the piston 26, ensuring the high efficiency of power transmission. A check valve 2 28 is installed on the inner wall of the shunt pipe 22. The check valve 2 28 further ensures that the liquid can only flow in one direction, preventing the liquid from flowing back during the supercharging process and maintaining the stable working pressure of the system.

[0037] Embodiment 2: In order to further increase the pressure generated during demolding, as Figure 1 and Figure 4As shown: In this solution, the auxiliary boosting assembly 3 includes an auxiliary pipe 31. One end of the auxiliary pipe 31 is fixedly connected to the boosting pipe 25. A check valve three 32 is installed on the inner wall of the auxiliary pipe 31. A check valve four 33 is installed on the side of the inner wall of the shunt pipe 22 away from the check valve two 28. In order to further increase the pressure generated during demolding, when the piston 26 moves towards the top, the auxiliary pipe 31 can directly receive the boosting liquid from the boosting pipe 25, ensuring that the auxiliary boosting assembly 3 can quickly participate in the boosting process when necessary, thereby providing additional pressure support for demolding. The setting of the check valve three 32 is to control the flow direction of the liquid, ensuring that the liquid can only flow from the boosting pipe 25 to the auxiliary boosting assembly 3 and cannot flow reversely. Similarly, the check valve four 33 also prevents the liquid from flowing back when under pressure. This configuration enables the shunt pipe 22 to effectively distribute the flow direction of the boosting liquid, thereby providing additional pressure in the case of the active boosting assembly 2 during the demolding process, thus enhancing the pressure output during demolding.

[0038] Furthermore, as Figure 1 - Figure 2 As shown: The support assembly 4 includes a support frame 41. The outside of the air cylinder 27 is fixedly connected to the support frame 41. The bottom end of the support frame 41 is fixedly connected to the bracket 1. A positioning block 42 is fixedly connected to one side of the support frame 41. The inside of the positioning block 42 is fixedly connected to the outside of the liquid delivery pipe 21. The outside of the air cylinder 27 is fixedly connected to the support frame 41. This connection method ensures the stability and accuracy of the air cylinder 27 during operation, preventing position deviation or functional failure caused by vibration or external interference. The bottom end of the support frame 41 is fixedly connected to the bracket 1. This design enables the support frame 41 to be firmly fixed on the basic bracket 1, providing a reliable support function. In addition, the positioning block 42 can effectively prevent the liquid delivery pipe 21 from shifting or loosening during operation, thereby ensuring that the liquid delivery path always remains on the predetermined track.

[0039] Furthermore, as Figure 1 As shown: The die-casting assembly 5 includes hydraulic pipelines 51. There are two hydraulic pipelines 51. One end of each of the two hydraulic pipelines 51 is fixedly connected to the liquid delivery pipe 21. One end of one of the hydraulic pipelines 51 is fixedly connected to a hydraulic cylinder one 52, and one end of the other hydraulic pipeline 51 is fixedly connected to a hydraulic cylinder two 53. The driving ends of the hydraulic cylinder one 52 and the hydraulic cylinder two 53 are fixedly connected to a mold mounting plate 54. The two hydraulic pipelines 51 ensure that the hydraulic system can simultaneously transmit hydraulic oil to different components, enabling the hydraulic oil to directly flow into the hydraulic pipelines 51 from the liquid delivery pipe 21, ensuring the stable and continuous oil supply of the hydraulic system. The design of the hydraulic cylinder one 52 and the hydraulic cylinder two 53 can jointly drive the mold mounting plate 54 to keep it moving smoothly and precisely during die-casting.

[0040] Working principle:

[0041] As Figure 1 - Figure 4 shown below:

[0042] In use: First, the top end of the pressure-increasing pipe 25 is fixedly connected to a cylinder 27, and the driving end of the cylinder 27 is fixedly connected to the top end of a piston 26. When increasing the pressure by driving the movement of the piston 26, the liquid delivery pipe 21 of the active pressure-increasing assembly 2 delivers liquid to various parts of the system through a shunt pipe 22 and a bifurcation pipe 23. The liquid delivery pipe 21 evenly distributes the liquid through the shunt pipe 22 and can reach different working areas. The bifurcation pipe 23 further shunts the liquid. Among them, check valve one 24 and check valve two 28 ensure that the liquid can only flow in one direction and prevent backflow, thereby maintaining the stable working pressure of the system. Subsequently, at the connection of the shunt pipe 22 of the pressure-increasing pipe 25, the piston 26 pushes the liquid to the shunt pipe 22. During the demolding process, the auxiliary pressure-increasing assembly 3 is connected to the pressure-increasing pipe 25 through an auxiliary pipe 31. When the piston 26 moves upward, the auxiliary pipe 31 directly receives the pressurized liquid from the pressure-increasing pipe 25 and then flows to the shunt pipe 22 to achieve the effect of double pressure increase. Finally, the hydraulic oil under pressure is delivered to a first hydraulic cylinder 52 and a second hydraulic cylinder 53 through a hydraulic pipeline 51, and jointly drives a mold mounting plate 54 to keep it moving smoothly and precisely during die casting.

[0043] The above is only a preferred embodiment of the present invention and is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
