[0029] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0030] Example:

[0031] Please see attached Figure 1 - Attachment Figure 8 The embodiment of the present invention provides an amorphous alloy die-casting device, including a mounting base plate 1 and a movable mold 4, a cooling seat 6 is mounted on the middle side of the top of the mounting base plate 1, the movable mold 4 is arranged directly above the cooling seat 6, the top of the cooling seat 6 is detachably connected with a fixed mold 8, the top four corners of the fixed mold 8 are fixedly connected with plug blocks 505, the plug block 505 is provided with a cavity, the interior of the cavity is elastically connected with a wedge block 506 through a first spring 507, the outer surface of the wedge block 506 is arranged as an inclined surface, and the wedge block 506 can be retracted into the interior of the cavity when it contacts the component, the bottom four corners of the movable mold 4 are provided with slots 504, the interior of the movable mold 4 is rotatably connected with a bidirectional screw 502, the external thread of the bidirectional screw 502 is connected to two movable plates 503, one end of the bidirectional screw 502 is fixedly connected with a rotating knob 501, and a cooling component is mounted inside the cooling seat 6, and the cooling component is used to quickly cool the casting inside the cooling seat 6.

[0032] Specifically, the mounting base 1 is the supporting base of the entire die-casting device, carrying key components such as the movable mold 4, the fixed mold 8, and the cooling seat 6, and ensuring their stability and position accuracy. The movable mold 4 can move up and down to close or separate with the fixed mold 8 to form a casting cavity. The outer surface of the wedge block 506 is designed as an inclined surface, which is used to cooperate with the slot 504 of the movable mold 4 during the closing process to ensure the seal between the fixed mold 8 and the movable mold 4.

[0033] When the electric telescopic rod 3 is started, the movable mold 4 moves downward until the movable mold 4 is molded with the fixed mold 8. During the mold closing process, the wedge block 506 first contacts the inner wall of the slot 504 at the bottom end of the movable mold 4. Since the outer surface of the wedge block 506 is designed as an inclined surface, the wedge block 506 will retract into the cavity of the insert block 505 under the action of external force. At this time, the first spring 507 is compressed, and the wedge block 506 further enters the upper inner side of the slot 504, and is pushed outward under the elastic force of the first spring 507 and stuck into the groove of the slot 504. This process ensures the sealing fixation between the movable mold 4 and the fixed mold 8. The sealing cooperation between the wedge block 506 and the slot 504 ensures the precise sealing of the mold during the mold closing process, avoids casting defects caused by poor sealing, and improves the forming accuracy of the casting.

[0034] When the casting is completed, the operator can rotate the knob 501, which will drive the bidirectional screw 502 to rotate. The bidirectional screw 502 drives the two moving plates 503 to move away from each other in a certain direction, so that the wedge block 506 is retracted from the slot 504 into the cavity of the insert block 505.

[0035] At this time, the electric telescopic rod 3 will shrink, driving the movable mold 4 to move upward, and releasing the mold clamping state between the movable mold 4 and the fixed mold 8.

[0036] The cooling assembly includes a cooling box 701 fixedly connected to the bottom of the installation base plate 1, and the outside of the cooling box 701 is connected with a first connecting pipe 702 and a second connecting pipe 703 in sequence. A storage box 704 is fixedly connected to one side of the top of the installation base plate 1, and a pump body 705 is installed on the top of the storage box 704. The output end of the pump body 705 is fixedly connected to the second transport pipe 707, and the input end of the pump body 705 is fixedly connected to the first transport pipe 706. A cooling cavity 708 is opened on the top of the cooling seat 6. One end of the second connecting pipe 703 is connected to the inside of the storage box 704, one end of the first connecting pipe 702 is connected to the inner wall of the cooling cavity 708, one end of the first transport pipe 706 is connected to the top of the storage box 704, and one end of the second transport pipe 707 is connected to the inner wall of the cooling cavity 708. The outer wall of the fixed mold 8 is installed with a plurality of heat exchange ribs.

[0037] Specifically, the storage box 704 is located on one side of the top of the installation base plate 1 and is used to store the coolant. The storage box 704 is filled with coolant, and the coolant is transported by the pump body 705. The function of the pump body 705 is to suck out the coolant in the storage box 704 and transport it to the cooling cavity 708 and the cooling box 701 through the pipeline system.

[0038] This cooling cavity 708 is located at the top of the fixed mold 8 and is the area where the coolant flows. The coolant flows here and exchanges heat with the heat exchange ribs on the inner wall of the fixed mold 8, thereby effectively reducing the temperature of the fixed mold 8 and helping to accelerate the cooling process of the liquid. The outer wall of the fixed mold 8 is equipped with a plurality of heat exchange ribs, the function of which is to increase the contact area with the coolant, thereby improving the heat exchange efficiency. When the coolant flows through the cooling cavity 708, it exchanges heat with these heat exchange ribs, absorbs the heat in the fixed mold 8, and reduces the temperature of the inner wall of the fixed mold 8.

[0039] During the process of synthesizing the amorphous alloy, liquid is injected into the molding cavity of the fixed mold 8 for cooling and forming.

[0040] When the cooling process begins, the pump body 705 starts to transport the coolant in the storage tank 704 to the cooling chamber 708 through the first transport pipe 706. In the cooling chamber 708, the coolant exchanges heat with the heat exchange ribs, absorbs the heat in the fixed mold 8, and reduces the temperature of the fixed mold 8, thereby accelerating the cooling and forming process of the alloy liquid.

[0041] After cooling is completed, the coolant flows back to the cooling box 701 through the first connecting pipe 702. After the coolant enters the cooling box 701, the temperature of the coolant is further reduced by the heat dissipation fins and the exhaust fan.

[0042] After the cooling of the coolant is completed, it flows back to the storage tank 704 through the second connecting pipe 703, forming a circulation flow of the coolant to maintain the cooling effect of the system.

[0043] The top rear side of the installation bottom plate 1 is fixedly connected with a top plate 2 , two electric telescopic rods 3 are installed on the top of the top plate 2 , and the top of the movable mold 4 is fixedly connected to the output ends of the two electric telescopic rods 3 .

[0044] The top left and right sides of the cooling seat 6 are provided with installation cavities 904, the inner wall of the installation cavity 904 is slidably connected with a movable plate 905, the outer surface of the movable plate 905 is rotatably connected with two swing rods 906, one side of the movable plate 905 is fixedly connected with a second spring 908, the other side of the movable plate 905 is fixedly connected with a driving rod 901, the interior of the installation cavity 904 is provided with a limiting groove 907, the interior of the limiting groove 907 is slidably connected with two insertion rods 903, and the left and right sides of the fixed mold 8 are fixedly connected with two installation blocks 902. The interior of the installation block 902 is provided with a slot, and the interior of the slot is plugged with one end of the insertion rod 903.

[0045] Specifically, the installation cavity 904 is a space for accommodating the movable plate 905, and the movable plate 905 is allowed to slide along the inner wall. The swing rod 906 is connected to the movable plate 905. The function of the swing rod 906 is to cause the movement of the insertion rod 903 through the movement of the movable plate 905, thereby driving the disassembly of the fixed mold 8. The second spring 908 is connected to one side of the movable plate 905 to provide a restoring force to help the movable plate 905 return to its original position after the driving rod 901 acts. The limiting groove 907 is opened in the installation cavity 904, and the insertion rod 903 slides along the inner wall of the limiting groove 907 to limit its movement range.

[0046] Mounting block 902: fixed on the left and right sides of the fixed mold 8, with slots inside the mounting block 902, plugged with one end of the plug rod 903. The movement of the plug rod 903 will release the plugging state, so that the fixed mold 8 can be disassembled.

[0047] During operation, by squeezing the driving rod 901 inward, the movable plate 905 is pushed to slide along the inner wall of the mounting cavity 904. When the movable plate 905 moves, the swing rod 906 on the outer surface of the movable plate 905 will swing. The swing of the swing rod 906 drives the insertion rod 903 to move along the inner wall of the limiting groove 907. The movement of the insertion rod 903 causes one end of the insertion rod 903 to disengage from the slot inside the mounting block 902. When one end of the insertion rod 903 disengages from the slot of the mounting block 902, the connection between the fixed mold 8 and the mounting block 902 is released, and the staff can easily move the fixed mold 8 upward to complete the disassembly of the fixed mold 8.

[0048] The main purpose of disassembling the fixed mold 8 is to facilitate the staff to disassemble the fixed mold 8, so that the inner wall of the cooling cavity 708 can be cleaned. By regularly cleaning the inner wall of the cooling cavity 708, dirt accumulation can be avoided, thereby maintaining good heat exchange efficiency between the heat exchange ribs and the coolant, thereby improving the overall performance of the cooling system.

[0049] One end of the second spring 908 is fixedly connected to the inner wall of the limiting groove 907, and one end of the two swinging rods 906 is respectively rotatably connected to the outer wall of the insertion rod 903 at the corresponding position. The longitudinal section of the slot 504 is set to be L-shaped, and the outer part of the movable plate 503 is slidably connected to the inner wall of the slot 504. A plurality of heat dissipation fins are installed inside the cooling box 701, and a plurality of exhaust fans are installed on the top of the cooling box 701, which are used to discharge the heat of the coolant inside the cooling box 701.

[0050] Specifically, the cooling box 701 is equipped with a plurality of heat dissipation fins, the function of which is to increase the surface area in contact with the coolant and help dissipate heat more effectively. The heat dissipation fins are made of aluminum, a metal material, and they can accelerate the heat conduction in the coolant to achieve a better cooling effect. A plurality of exhaust fans are installed on the top of the cooling box 701, and the function of the exhaust fans is to discharge the heat dissipated from the inside of the cooling box 701 through the heat dissipation fins. The coolant absorbs the heat generated by the equipment during the cooling process, and the exhaust fans help to discharge the heat from the cooling box 701, ensuring the continuous and efficient operation of the cooling system.

[0051] Working principle: When the device is used, the movable mold 4 is driven to move downward by starting the electric telescopic rod 3 until the movable mold 4 and the fixed mold 8 are closed. During the closing process, the wedge block 506 will first contact the inner wall of the bottom of the slot 504. Since the outer surface of the wedge block 506 is an inclined surface, the wedge block 506 will retract into the inside of the plug block 505 and make the first spring 507 in a compressed state. When the wedge block 506 completely enters the upper side of the inner part of the slot 504, the elastic force of the first spring 507 drives the wedge block 506 to move outward, and the wedge block 506 is stuck in the groove of the slot 504, so as to complete the sealing and fixing of the fixed mold 8 and the movable mold 4, thereby reducing molding defects and improving molding accuracy.

[0052] After the film is closed, liquid for synthesizing amorphous alloy is injected into the fixed mold 8, and the liquid is cooled and formed through the molding cavity inside the fixed mold 8. At this time, the cooling liquid inside the storage box 704 is transported to the inside of the second transport pipe 707 by starting the pump body 705, and is transported to the cooling cavity 708 through the second transport pipe 707. At this time, the cooling liquid and the heat exchange ribs undergo heat exchange reaction, thereby reducing the temperature of the inner wall of the fixed mold 8 and accelerating the forming of the amorphous alloy. After completion, the cooling liquid flows back to the cooling box 701 through the first connecting pipe 702, and is cooled again through the heat dissipation fins and the exhaust fan. After cooling, it flows back to the inside of the storage box 704 through the second connecting pipe 703 to realize the recycling of the cooling liquid.

[0053] After the molding is completed, the bidirectional screw 502 is driven to rotate by rotating the knob 501, thereby further driving the two movable plates 503 to move away from each other until the wedge block 506 is retracted into the insert block 505. At this time, the output end of the electric telescopic rod 3 contracts and drives the movable mold 4 to move upward, and the wedge blocks 506 are separated from each other from the inside of the slot 504, thereby releasing the mold-closing state of the movable mold 4 and the fixed mold 8.

[0054] Finally, the movable plate 905 is moved along the inner wall of the installation cavity 904 by squeezing the driving rod 901 inward until one end of the swing rod 906 is swung, and under the traction force of the swing rod 906, the insertion rod 903 is driven to move along the inner wall of the limiting groove 907 until one end of the insertion rod 903 is no longer engaged with the slot inside the installation block 902. At this time, the staff moves the fixed mold 8 upward to complete the disassembly of the fixed mold 8, thereby facilitating the staff to clean the dirt on the inner wall of the cooling cavity 708 to ensure the heat exchange effect.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
