[0002] A die-casting machine is a machine used for pressure casting. It is primarily used to hydraulically inject molten metal into a mold, where it is cooled and formed into a solid metal casting. Depending on how the molten metal is injected, die-casting machines can be divided into hot-chamber and cold-chamber machines. Hot-chamber machines melt the metal by heating it and then inject it into the mold. Cold-chamber machines, on the other hand, pour the molten metal into the injection chamber and then use an injection piston to push the liquid metal into the mold at high speed.

There is a certain distance between the first frame 2 and the second frame 7, and the distance is used to install the mold. Specifically, a first molding mold 3 is detachably provided on the side of the first frame 2, and a second molding mold 6 corresponding to the first molding mold 3 is provided on the side of the second frame 7.

[0026] It should be noted that the first molding die 3 is a fixed die, meaning it is stationary. A die-casting inlet is located on its side. At least one vent is also provided on either the first molding die 3 or the second molding die 6 to release pressure from within the mold. The second molding die 6 is a movable die, corresponding to the fixed die. However, the first molding die 3 can be either a male or female die, and the second molding die 6 can be either a male or female die. During use, the first molding die 3 and the second molding die 6 can simply be aligned.

[0027] The installation structure of the second molding die 6 will be described in detail below. Figure 1 As shown, the four corners of the second forming mold 6 are respectively provided with guide columns 8 vertically and detachably, and the guide columns 8 are respectively arranged vertically and movably in the second frame 7, so that the guide columns 8 can be freely extended and retracted in the second frame 7, in order to provide better support for the guide columns 8, as shown in FIG. Figure 1 and Figure 2 As shown, a guide seat 5 is movably mounted on each guide column 8, and the guide seat 5 is disposed on the second frame 7 so that the guide seat 5 supports the guide column 8;

[0028] Next, the ends of the guide posts 8 away from the second molding die 6 are connected to the connecting frame 9, as shown in FIG. Figure 1 As shown, the connecting frame 9 is an "I"-shaped frame, and a first hydraulic cylinder 11 parallel to the guide column 8 is also installed on the connecting frame 9. The first hydraulic cylinder 11 drives the guide column 8 to extend and retract in the second frame 7, thereby allowing the first molding die 3 and the second molding die 6 to close or open the mold.

[0029] Furthermore, two L-shaped frames 19 are symmetrically provided on one side of the second frame 7 away from the first frame 2. One end of the L-shaped frame 19 is connected to the side of the second frame 7, and the other end of the L-shaped frame 19 is connected to the base 1. The L-shaped frame 19 spans the side of the second frame 7, which can increase the supporting strength of the second frame 7. The second frame 7 can also serve as a carrier for installing the first hydraulic cylinder 11. Specifically, the first hydraulic cylinder 11 is located above the L-shaped frame 19 and is installed on the mounting seat 20, and then the mounting seat 20 is set on the top of the two L-shaped frames 19.

[0030] A die-casting mechanism is provided on one side of the die-casting molding mechanism. The die-casting mechanism has a heat preservation and heating function, which can prevent the molten metal from condensing inside it. The die-casting mechanism will be introduced below.

[0031] The die-casting mechanism includes a steel die-casting cylinder 18 with one end sealed. The end of the die-casting cylinder 18, away from the opening, is connected to the die-casting inlet via a connecting channel 15. Specifically, flanges are provided at both ends of the connecting channel 15 and then mounted on the die-casting cylinder 18. The bottom of the die-casting cylinder 18 is mounted on the base 1 via a second bracket 17. A heater 23 and a heat shield 16 covering the heater 23 are also provided on the surface of the die-casting cylinder 18. The heater 23 is a heating wire or heating rod distributed on the outside of the die-casting cylinder 18.

[0032] The heat shield 16 is made of two curved plates spliced together, and the edges of the two curved plates are detachably connected. Specifically, the edges of the two curved plates are fixed with bolts. A heat insulation layer is provided on the inner wall of each curved plate. The heat insulation layer is made of insulation materials such as insulation bricks, insulation ceramic plates, insulation cotton, insulation foam, or aerogel insulation board. This allows the heat shield 16 to seal the heat emitted by the heating body 23 and allow the heat to directly heat the die casting cylinder 18. The internal temperature of the die casting cylinder 18 must match the melting point of the molten metal to prevent the molten metal from agglomerating inside the die casting cylinder 18.

[0033] A die-cast piston 26 is provided in the die-cast cylinder 18 to match the die-cast piston 26. The die-cast piston 26 is coaxially arranged on one end of the piston shaft 14. The other end of the piston shaft 14 is connected to the second hydraulic cylinder 12. The second hydraulic cylinder 12 is arranged on the base 1 through the first bracket 13. Figure 2 As shown, the die casting cylinder 18 is provided with a hopper 4 on one side close to its opening. The hopper 4 is connected to the interior of the die casting cylinder 18. When in use, the operator pours the molten metal from the hopper 4 into the die casting cylinder 18. The hopper 4 should be closer to the connecting channel 15 than the die casting piston 26. When pouring the molten metal, Figure 5As shown, the die-casting piston 26 stays at the end of the die-casting cylinder 18 and seals the die-casting cylinder 18, so that the molten metal can only enter the die-casting cylinder 18 from the hopper 4 for storage. When pouring the molten metal, the amount of the molten metal must be controlled. A certain amount of steel ladle can be used to store the molten metal, and then the molten metal can be poured into the hopper 4.

[0034] When the die-casting piston 26 is driven forward by the second hydraulic cylinder 12, the die-casting piston 26 drives the molten metal into the connecting channel 15, and is finally injected from the connecting channel 15 into the cavity between the first forming die 3 and the second forming die 6 after the mold is closed. It should be noted that the connecting channel 15 is inclined upward. When the die-casting piston 26 retracts, the molten metal remaining in the connecting channel 15 can flow back into the die-casting cylinder 18, preventing the connecting channel 15 from being blocked. The connecting channel 15 is provided with a thermal insulation layer, and the thermal insulation layer is made of the same material as the thermal insulation layer in the thermal insulation cover 16.

[0035] Furthermore, in order to facilitate cleaning of the interior of the die casting cylinder 18 , the end of the die casting cylinder 18 away from its opening is sealed by a detachable end cover 25 , and the edge of the end cover 25 is fastened to the end of the die casting cylinder 18 by bolts.

[0036] Furthermore, the first rack 2 is located in the first shell 21, the second rack 7 is located in the second shell 22, the bottom of the first shell 21 and the second shell 22 are provided on the base 1, and the first shell 21 and the second shell 22 are both provided with a heat dissipation system, which is an exhaust fan provided on the first shell 21 and the second shell 22, or the heat dissipation system is an air conditioning refrigeration system.

[0037] In summary, the present application further includes a control unit provided on the base 1 and a hydraulic control station 10 connected to the control unit, the hydraulic control station 10 being connected to the first hydraulic cylinder 11 and the second hydraulic cylinder 12 via oil pipes respectively;

[0038] A temperature sensor extending to the die casting cylinder 18 is provided on the heat shield 16 and is used to monitor the temperature of the die casting cylinder 18;

[0039] The control unit is a PLC logic controller or a host computer. The control unit is respectively connected to the operation panel 24, the die casting cylinder 18 and the heating body 23. The operation panel 24 is set on the surface of the first shell 21 or the second shell 22. The control unit is equivalent to the "brain", allowing each component to operate in the set manner.

[0040] Based on the above implementation, further optimization can be performed. In order to make the first rack 2 more stable, a stabilizing frame (such as Figure 1 As indicated by the middle arrow A, the stable frame and the first frame 2 are arranged in a triangle.

[0041] Based on the above implementation, further optimization can be done to facilitate material collection, such as Figure 6 As shown, a material-retrieving robot is provided on one side between the first rack 2 and the second rack 7. The material-retrieving robot is a six-axis robotic arm with a manipulator installed at the end of the six-axis robotic arm.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
