It is installed on the surface of the mounting ear 2 to control the entire demoulding and vacuum treatment process to achieve automated operation. Specific embodiment two:

[0031] Reference Figure 1-5 According to the above specific embodiments, the following contents are further disclosed:

[0032] In actual use, in order to facilitate the rapid forming and solidification of the aluminum liquid, an air duct or a cooling pipe can be connected to the side of the vacuum pump 8, and the vacuum pump 8 can be replaced with a blower or an air supply pump to blow external air into the aluminum liquid to accelerate the rapid solidification of the aluminum liquid. In actual use, according to actual use requirements, the vacuum pump 8 can be set on one side of the mold body 1 to ensure that the bubbles inside the aluminum liquid are reduced while accelerating the solidification of the aluminum liquid.

[0033] In actual use, the micro pores 7 further disclose the following:

[0034] Aperture: The aperture of the micro pore 7 should be designed to be small enough to ensure that the aluminum liquid will not leak due to the pore being too large during the aluminum liquid injection process. Usually, the aperture size is determined according to the fluidity and viscosity of the aluminum liquid, and is generally between 0.1mm and 1mm.

[0035] Distribution: The micro pores 7 should be evenly distributed on the inner wall of the L-shaped stripper plate 5 to ensure that all areas inside the molten aluminum can be effectively vacuumed. The distribution density also needs to be adjusted according to the bubble generation situation of the molten aluminum to achieve the best degassing effect;

[0036] Shape and arrangement: The shape of the micro pores 7 can be circular, elliptical or other suitable shapes. The selection of the specific shape should take into account the difficulty of processing and the degassing effect. The pores should be arranged according to a certain pattern, such as equidistant arrangement or staggered arrangement, to optimize the vacuum effect and reduce the difficulty of processing.

[0037] Material and surface treatment: The material of the L-shaped stripping plate 5 and its micro-pores 7 should have good high temperature resistance and corrosion resistance to ensure stability and durability in the high temperature environment of molten aluminum. The pore surface should be properly treated, such as polishing or coating with a high temperature resistant coating, to reduce friction and adhesion between the molten aluminum and the pore wall and improve demoulding efficiency.

[0038] When designing the micro-pores 7, it is crucial to ensure a good seal between the pores and the air duct 9 to prevent air leakage during vacuuming, which could compromise the degassing effect. The micro-pores 7 are prone to clogging or contamination during use, so they should be cleaned and maintained regularly to ensure they remain unobstructed. The mold should also be thoroughly cleaned before and after use to prevent residue from damaging the pores. The design of the micro-pores 7 should fully consider vacuuming efficiency to ensure that bubbles within the molten aluminum can be effectively removed within a reasonable timeframe. This may require optimizing the pore layout and parameters through testing and simulation. Operator safety should be fully considered during the design process to ensure that the micro-pores 7 and their associated components pose no risk to personnel during operation. Furthermore, safety procedures should be strictly adhered to during mold use to prevent accidents. The design of the micro-pores 7 should be compatible with the mold main body 1, air duct 9, and vacuum pump 10, ensuring smooth operation of the entire system and achieving the desired degassing effect. This requires thorough communication and coordination from the initial design stages. Specific embodiment three:

[0040] Reference Figure 1-5 According to the above specific embodiments, the following contents are further disclosed:

[0041] In actual use, the guide hydraulic cylinder 12 and the dual-axis cylinder 13 are controlled by the controller 4. Specifically, the controller 4 is the "brain" of the entire system, responsible for receiving input signals such as operating instructions, sensor feedback, etc. After internal processing, it outputs control signals to the actuators, such as the guide hydraulic cylinder 12 and the dual-axis cylinder 13, to achieve preset actions and functions.

[0042] Control method of the guide hydraulic cylinder 12: The controller 4 first receives a command signal from the operation interface or sensor, such as a "start demolding" signal, analyzes and processes the received signal, determines the action and parameters to be performed, and outputs a control signal. Based on the processing result, the controller 4 outputs a control signal to the solenoid valve or proportional valve of the guide hydraulic cylinder 12. The control signal may include parameters such as pressure, flow, and direction, which are used to adjust the extension and retraction action of the hydraulic cylinder.

[0043] Execution action: After receiving the control signal, the hydraulic cylinder realizes vertical extension or shortening by changing the pressure and flow of the hydraulic oil. In this example, the guide hydraulic cylinder 12 is mainly used to push the connecting frame 15 and the L-shaped stripping plate 5 to rise as a whole, so as to realize the rapid demolding of the aluminum ingot.

[0044] Control method of the dual-axis cylinder 13: signal reception and processing are similar to those of the guide hydraulic cylinder 12. The controller 4 receives command signals from the operation interface or sensor, such as the "clamping and stripping template" signal, analyzes and processes the signal, determines the action and parameters that the dual-axis cylinder 13 needs to perform, and outputs a control signal. The controller 4 outputs a control signal to the air control valve or solenoid valve of the dual-axis cylinder 13. The control signal may include parameters such as the extension and contraction direction, speed, and force of the cylinder.

[0045] Execution action: After receiving the control signal, the double-axis cylinder 13 realizes the clamping and loosening action of the cylinder by opening and closing the air circuit or changing the air pressure. In this example, the double-axis cylinder 13 is mainly used to clamp the L-shaped demolding plate 5 and cooperate with the guide hydraulic cylinder 12 to realize the demolding of the aluminum ingot.

[0046] In summary:

[0047] 1. An L-shaped limiting groove 3 is provided inside the mold body 1 to engage the L-shaped stripper plate 5, and micro air holes 77 are provided on the side of the L-shaped stripper plate 5 to connect with the air guide pipe 9 and the air pump 8. After the aluminum liquid is injected into the mold body 1, the aluminum liquid can be vacuumed by the air pump 8 in cooperation with the air guide pipe 9, thereby processing the bubbles generated inside the aluminum liquid during pouring, preventing the formation of holes inside the aluminum ingot after forming, avoiding the generation of bubbles, and improving the forming quality of the aluminum ingot;

[0048] 2. The aluminum liquid is poured after the L-shaped stripping plate 5 is engaged with the L-shaped limiting groove 3 inside the mold body 1. After the aluminum liquid solidifies, the L-shaped stripping plate 5 is clamped by the externally connected double-axis cylinder 13, and the guide hydraulic cylinder 12 is cooperated to extend it in the vertical direction to achieve rapid demolding and removal of the aluminum ingot after forming. Compared with the traditional method of vertically removing from the bottom surface of the mold body 1, the structure of the non-penetrating side of the present application is used to remove the aluminum ingot, which can achieve rapid demolding and leakage prevention during aluminum liquid casting. It has a simple structure, is easy to control, and is convenient for rapid demolding and use of the aluminum ingot.
