Description

Technical Field

[0001] The present application relates to the field of die-casting machines, and in particular to a high-speed die-casting machine. Background Art

[0002] At present, die casting is a commonly used casting process, which is widely used in the fields of automobile, electronics, aerospace, etc. The characteristic of this process is that high pressure is applied to the molten metal by using the mold cavity to achieve rapid molding. The mold is usually made of high-strength alloy to ensure its durability and precision. Most die castings are non-ferrous metals such as zinc, copper, aluminum, magnesium, lead, tin and their alloys. Depending on the type of die casting, a cold chamber die casting machine or a hot chamber die casting machine can be selected. This process not only improves production efficiency, but also improves the quality and performance of castings, meeting the needs of modern industry for precision parts.

[0003] Related technologies In order to achieve the melting of metal raw materials, heating devices are usually equipped. Common heating methods include resistance heating, induction heating and gas heating. Resistance heating is the generation of heat by resistance wire under the action of electric current, which is suitable for small equipment; induction heating uses electromagnetic fields to generate eddy currents inside the metal, thereby generating heat, which is suitable for large equipment; gas heating directly heats the furnace by burning natural gas or other fuels, which is suitable for continuous production scenarios. These heating methods have their own characteristics and are widely used in practical applications, and can effectively complete the melting process of metal raw materials.

[0004] However, existing heating devices have some shortcomings, especially in terms of heating efficiency and uniformity. Although traditional resistance heating and gas heating methods can achieve a certain heating effect, they are prone to uneven temperatures during the heating process, resulting in insufficient melting of the metal in the furnace, affecting the quality of the final casting. In addition, these heating methods often have high energy consumption, and long-term operation will increase production costs. Therefore, how to improve heating efficiency and uniformity and reduce energy consumption has become a technical problem that needs to be solved urgently. Summary of the invention

Through the reasonable structural layout and the efficient heating device 5, the rapid and uniform melting of the metal raw material is achieved, and the production efficiency and the quality of the casting are improved.

[0039] Reference Figure 1 and Figure 3A bearing seat 11 is fixedly arranged on the base 1, and an assembly cavity 12 is provided on the side of the bearing seat 11 away from the forming device 3. The end of the assembly cavity 12 away from the forming device 3 is open, and a blocking door 14 is provided at the opening to prevent the internal heat from diffusing to the outside. The furnace device 4 is fixed on the top of the bearing seat 11, and the bottom of the furnace device 4 is located inside the assembly cavity 12, and the outer wall of the furnace device 4 does not contact the inner wall of the assembly cavity 12, thereby providing an installation space for the heating device 5. In this embodiment, the furnace device 4 can be a heating pot for accommodating molten metal materials.

[0040] Reference Figure 4 In this embodiment, the heating device 5 includes a heating mechanism 51 and a mounting seat 52. The mounting seat 52 is arranged on the base 1. A cavity 521 is formed on the top of the mounting seat 52. The heating mechanism 51 is fixedly arranged on the inner wall of the cavity 521. The heating mechanism 51 is used to heat the furnace device 4. The heating mechanism 51 is arranged on the inner wall of the cavity 521 of the mounting seat 52, so that the furnace device 4 can be directly and evenly heated, which significantly improves the heating efficiency and uniformity, ensures that the metal raw materials in the furnace device 4 can be quickly and fully melted, thereby further improving the quality and consistency of the casting. At the same time, this design also helps to optimize the heat energy transfer path, reduce energy loss, and reduce energy consumption.

[0041] Reference Figure 4 The heating device 5 also includes a heat insulation layer 53, which is located between the heating mechanism 51 and the mounting seat 52. The heating mechanism 51 and the mounting seat 52 have a clamping effect on the heat insulation layer, so as to achieve simultaneous installation and fixation of the heating mechanism 51 and the heat insulation layer 53. In this embodiment, the specific material of the heat insulation layer 53 is asbestos. The heat insulation layer 53 is arranged between the heating mechanism 51 and the mounting seat 52, which effectively reduces the heat loss during the heating process, improves the efficiency of heat energy utilization, and further enhances the heat preservation performance and heating efficiency of the heating device 5. This not only helps to maintain the stable melting state of the metal raw materials in the furnace device 4, but also reduces energy consumption, prolongs the service life of the heating device 5, and ensures that the temperature of the surrounding environment will not be too high, thereby improving the safety and reliability of the overall equipment.

[0042] Reference Figure 4 and Figure 5The heating mechanism 51 includes a metal heating wire 511, a power supply mechanism 512 and a plurality of ceramic parts 513. The metal heating wire 511 passes through the plurality of ceramic parts 513 at the same time. The metal heating wire 511 and the plurality of ceramic parts 513 are fixedly arranged on the plurality of inner side walls of the cavity 521. The power supply mechanism 512 is arranged on the outer side wall of the mounting seat 52. The metal heating wire 511 is electrically connected to the power supply mechanism 512. At the same time, the power supply mechanism 512 is connected to an external power source through a wire or the like, so as to provide electric energy to the entire die-casting machine. The heating mechanism 51 utilizes the metal heating wire 511 to generate resistance heat under the action of the power supply mechanism 512. The plurality of ceramic parts 513 not only play the role of supporting and fixing the metal heating wire 511, but also can effectively isolate the heat and protect the mounting seat 52 from being affected by high temperature. The heating is made more direct and efficient, and the heat distribution is more uniform, thereby significantly improving the melting efficiency of the metal raw material and the quality of the casting, while ensuring the stability and durability of the heating device 5. In this embodiment, the metal heating wire 511 is specifically made of a graphene composite conductor, which has the advantages of high heat resistance and long life, and saves 50% electricity compared to ordinary heating wires.

[0043] Reference Figure 5 Specifically, the metal heating wire 511 passes through a rectangular array composed of multiple ceramic pieces 513 in a specific path, and the multiple ceramic pieces 513 located on the same inner wall inside the cavity 521 are arranged in a rectangular grid, and each ceramic piece 513 has holes passing through both ends thereof. The metal heating wire 511 enters from one end of these holes and exits from the other end, thereby passing through multiple ceramic pieces 513 in sequence. Two adjacent ceramic pieces 513 are fixedly connected, and each ceramic piece 513 is fixedly connected to the inner wall of the mounting seat 52, thereby increasing the firmness of the installation of the multiple ceramic pieces 513.

[0044] Reference Figure 1 and Figure 3 The mounting seat 52 is slidably matched with the assembly cavity 12, and a clearance opening 522 is provided on one side of the mounting seat 52 close to the molding device 3 to ensure that the furnace device 4 will not interfere with the mounting seat 52 during the process of pushing and pulling the mounting seat 52. The mounting seat 52 is slidably matched with the assembly cavity 12, so that the mounting seat 52 can slide conveniently on the bearing seat 11, thereby realizing the position adjustment of the furnace device 4 relative to the molding device 3.

[0045] Reference Figure 3 A handle 523 is fixedly arranged on one side of the mounting seat 52 away from the avoidance opening 522, and the handle 523 is located on the upper part of the power supply mechanism 512. It is convenient for the staff to pull the mounting seat 52 out of the assembly wall, so as to facilitate the inspection and maintenance of the heating mechanism 51.

[0046] Reference Figure 1In this embodiment, the transverse movement device 2 includes a transverse movement seat 21 and two first oil cylinders 22. The two first oil cylinders 22 are arranged on the base 1. The piston rods of the two first oil cylinders 22 are fixedly connected to the transverse movement seat 21. The two first oil cylinders 22 are used to drive the transverse movement seat 21 to move toward or away from the base 1. The molding device 3 is arranged on the transverse movement seat 21, and the molding device 3 is used to mold parts.

[0047] Reference Figure 1 and Figure 6 Specifically, the molding device 3 includes a die base 31, a fixed die 32, a movable die 33, a second oil cylinder 34 and a connecting rod mechanism 35. The die base 31 includes two support blocks 311 and four guide rods 312. The two support blocks 311 are fixed on the transverse seat 21. The four guide rods 312 extend in the horizontal direction, and the two ends of each guide rod 312 are respectively fixedly connected to the two support blocks 311, forming a stable die base 31. The fixed die 32 is fixed on one of the support blocks 311, and the movable die 33 is sleeved on the four guide rods 312, and a sliding fit is achieved between the movable die 33 and the guide rods 312. The connecting rod mechanism 35 includes a first connecting rod 351 and a second connecting rod 352. One end of the first connecting rod 351 is rotatably connected to the movable die 33, and one end of the second connecting rod 352 is rotatably connected to the other support block 311. The other end of the first connecting rod 351 is also connected to the other end of the second connecting rod 352 by a rotation connection, forming a connecting rod mechanism 35 that can move flexibly. The second oil cylinder 34 is rotatably set on the transverse displacement seat 21, and the piston rod of the second oil cylinder 34 is fixedly connected to the end of the first connecting rod 351. By controlling the extension and contraction of the piston rod of the second oil cylinder 34, the connecting rod mechanism 35 can be driven to move, thereby driving the movable mold 33 to move horizontally. An ejection oil cylinder 36 is fixedly set on the side of the fixed mold 32 away from the movable mold 33. The piston rod of the ejection oil cylinder 36 can penetrate the fixed mold 32 and slide relative to the fixed mold 32, providing an ejection function for the molded product, which is convenient for the removal of the product.

[0048] Reference Figure 6 When it is necessary to form a product, first, the piston rod of the second oil cylinder 34 is controlled to extend to push the connecting rod mechanism 35 composed of the first connecting rod 351 and the second connecting rod 352 to move. Since the first connecting rod 351 is rotatably connected to the movable mold 33, and the second connecting rod 352 is rotatably connected to another support block 311, when the piston rod is extended, it will drive the movable mold 33 to move horizontally along the guide rod 312 and gradually approach the fixed mold 32. When the movable mold 33 and the fixed mold 32 are completely closed, the product molding operation can be carried out. After molding, the piston rod of the second oil cylinder 34 is controlled to retract, so that the connecting rod mechanism 35 moves in the opposite direction, driving the movable mold 33 along the guide rod 312 away from the fixed mold 32. At this time, the piston rod of the ejection oil cylinder 36 can be extended to eject the molded product from the mold, thereby completing a complete molding cycle.

[0049] Reference Figure 1 and Figure 7 In this embodiment, the injection device 6 is located above the furnace device 4. Specifically, the injection device 6 includes a gooseneck structure 61, an injection oil cylinder 63, an injection nozzle 64, a nozzle heater 65 and a heat preservation nut 66. In this embodiment, three gooseneck mounting shafts 62 are fixedly provided on one side of the gooseneck structure 61 close to the base 1, and the other ends of the three gooseneck mounting shafts 62 are fixedly connected to the base 1, so that the gooseneck structure 61 is installed on the base 1, and the injection oil cylinder 63 is installed on the gooseneck structure 61, and an injection plunger is provided. The injection nozzle 64, the nozzle heater 65 and the heat preservation nut 66 are connected to the base 1, and together constitute a complete and stable injection system.

[0050] Reference Figure 7 During the casting process, the injection device 6 drives the injection oil cylinder 63 to press the injection plunger downward, thereby pushing the molten metal stored in the heating pot through the gooseneck structure 61 to the injection nozzle 64 and into the metal casting hole of the mold of the molding device 3. At the same time, the nozzle heater 65 maintains the appropriate temperature of the nozzle and the molten metal, and the insulation nut 66 reduces heat loss to ensure the smooth progress of the entire injection process. After the injection is completed, the piston of the injection oil cylinder 63 returns to its original position to prepare for the next injection, and the gooseneck structure 61 can be adjusted as necessary according to the casting requirements.

[0051] Reference Figure 1 and Figure 7 In order to prevent the molten metal from overflowing from the front end of the injection nozzle 64, the molding device 3 and the injection nozzle 64 are both inclined. The molding device 3 moves forward or backward to the injection nozzle 64 only in the mold closing state through the first oil cylinder 22. The movement process is limited to the operation of making the injection nozzle 64 contact with the mold matching surface and injecting molten metal, that is, the operation of contacting the injection nozzle after the mold closing and the operation of separating the injection nozzle 64 before the mold is opened after injection.

[0052] Reference Figure 1 The base 1 is also provided with an electric motor 8 and an oil pump 9. When the electric motor 8 is started, it drives the oil pump 9 to rotate, thereby sucking and pressurizing the hydraulic oil in the oil tank. The pressurized hydraulic oil is transported to various actuators of the die-casting machine through pipelines, such as the first oil cylinder 22, the second oil cylinder 34, the ejection oil cylinder 36 and the injection oil cylinder 63, etc., to drive them to work.

[0053] Continue to refer to Figure 1The base 1 is also provided with a pressure accumulator 10 and a nitrogen pressurizer 15. The pressure accumulator 10 is connected in parallel in the main circuit of the hydraulic system to store and release hydraulic energy. During the operation of the system, the pressure accumulator 10 can absorb the excess hydraulic energy in the system and store it as gas potential energy (provided by the nitrogen pressurizer 15). The nitrogen pressurizer 15 is used to fill the pressure accumulator 10 with nitrogen so that it has a certain pre-charge pressure. This pre-charge pressure helps the pressure accumulator 10 to better absorb and release hydraulic energy, and can also play a buffering role when the system pressure fluctuates.

[0054] Example 2 Reference Figure 8 , the difference between Example 2 and Example 1 is that: a sliding drive device 7 is provided on the bearing seat 11, and the sliding drive device 7 is used to drive the mounting seat 52 to move toward or away from the forming device 3. The sliding drive device 7 includes a support 71, a driving motor 72, a gear 73 and a rack 74. The support 71 is fixed to the lower surface of the bearing seat 11, the driving motor 72 is fixed on the support 71, and the gear 73 is sleeved on the output shaft of the driving motor 72 and fixedly connected to the output shaft of the driving motor 72. The rack 74 is fixed to the lower surface of the mounting seat 52, and a sliding groove 13 is provided at the bottom of the bearing seat 11. The rack 74 slides along the length direction of the sliding groove 13, and the gear 73 and the rack 74 are meshed with each other. Accurate positioning and stable movement of the mounting seat 52 are achieved. Specifically, the arrangement of the support 71 and the drive motor 72 ensures reliable transmission of the driving force, and the meshing structure of the gear 73 and the rack 74 enables the mounting base 52 to move smoothly in the sliding groove 13, thereby effectively avoiding position deviation caused by mechanical friction, simplifying the mechanical structure, reducing maintenance costs, and improving the overall reliability of the equipment.

[0055] The support 71 is provided with an adjustment groove 75, which extends in the horizontal direction; a bolt is inserted into the adjustment groove 75, and the bolt slides with the bearing seat 11. The bearing seat 11 is provided with an adjustment groove 75, which extends in the horizontal direction; a bolt is inserted into the adjustment groove 75, and the bolt slides with the bearing seat 11, so that the position of the bearing seat 11 can be finely adjusted, thereby ensuring the precise alignment between the furnace device 4 and the molding device 3, and improving the stability of the die casting process and the quality of the casting.

[0056] The setting of the sliding drive device 7 enables the mounting seat 52 to move accurately along the sliding groove 13 of the bearing seat 11, thereby realizing the position adjustment of the furnace device 4 relative to the molding device 3. This not only improves the working flexibility of the die-casting machine, but also ensures that the relative position between the furnace device 4 and the molding device 3 is accurate during each die-casting operation, further improving the quality and consistency of the casting. In addition, the use of the sliding drive device 7 simplifies manual operation, reduces labor intensity, and improves production efficiency.

[0057] In this embodiment, the high-speed die-casting machine also includes a control system for controlling the operation of the heating device 5, the traverse device 2, the injection device 6, and the sliding drive device 7 to realize the automation and precise control of the die-casting process. The automation and precise control of the die-casting process are realized. Specifically, the control system can coordinate the operation of the heating device 5, the traverse device 2, the injection device 6, and the sliding drive device 7 to ensure that each component operates according to predetermined procedures and parameters. This not only improves production efficiency and reduces errors caused by human intervention, but also improves the quality and consistency of castings. Especially under large-scale production and complex process requirements, automated control can significantly improve production stability and reliability.

[0058] The implementation principle of the embodiment of the present application is as follows: the furnace device 4 is arranged on the base 1, and the interior is used to load the metal raw materials to be melted; the heating device 5 is closely matched with the furnace device 4, and provides uniform and efficient heat energy to the furnace device 4 through an efficient heating method, so as to ensure that the metal raw materials can be melted quickly and fully; when the metal raw materials in the furnace device 4 are melted, the transverse device 2 starts to work, driving the molding device to move toward the furnace device 4 until the molding device 3 and the furnace device 4 reach a suitable relative position; after the molding device 3 reaches the predetermined position, the injection device 6 starts to work. It uses high pressure to transport the molten liquid metal in the furnace device 4 to the molding device 3 through a specific runner or nozzle; this process requires precise control of the flow rate and pressure of the liquid metal to ensure the quality of the casting; after the liquid metal enters the molding device 3, it cools and solidifies for a period of time to form the desired casting shape, and then the transverse device 2 is started again to take the molding device 3 away from the furnace device 4 for subsequent removal, cleaning and inspection; the present application can significantly improve the heating efficiency and uniformity through the heating device 5. This helps ensure that the raw metal material is melted quickly and fully within the furnace apparatus 4, thereby improving the quality and consistency of the castings.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
