Description

Technical Field

[0001] This utility model relates to the field of amorphous alloy die casting technology, and in particular to a horizontal vacuum die casting device for amorphous alloys. Background Technology

[0002] Amorphous alloys are metals whose atomic structure remains in a long-range disordered arrangement through alloy composition design and specific die-casting processes. Due to their unique advantages such as high mechanical properties, chemical stability, beautiful appearance, and elastic deformation behavior without plastic deformation, they are widely used in electronic components, wearable devices, decorative items, and mechanical parts. Currently, the main forming process for mass production of amorphous alloys is vacuum die casting using a mold with rapid cooling. Existing technologies include vertical and horizontal equipment used for vacuum die casting.

[0003] In vertical vacuum die casting equipment, the entire die casting equipment is housed within a vacuum chamber. The entire process—material dissolution, molten metal supply, die casting, mold opening and closing, and casting extraction—is all performed within the vacuum chamber. Figure 4 and Figure 6 As shown, the advantages of vertical vacuum die casting equipment are that it allows for die casting injection from the center of the mold during the die casting process. This method reduces the flow distance of the molten material to each cavity, making it easier to control and achieve balance in feeding, temperature, injection pressure, and ejection of each cavity to obtain higher quality products. Its disadvantages include the risk of residue being left on the mold surface due to molten material splashing during pouring, or fragments of the casting being scattered in the mold during removal. These residues must be removed manually by operators using methods such as argon gas injection, and the operator cannot easily observe the mold condition. During continuous operation, there is a risk of mold damage due to incomplete residue removal. Furthermore, the process of releasing the vacuum and repressurizing during equipment maintenance, repair, and mold replacement is lengthy, and personnel operating through the vacuum chamber are inconvenient, making automated cleaning and automated mold removal impossible.

[0004] Horizontal vacuum die casting equipment offers advantages over vertical equipment, including simpler structure, lower manufacturing costs, and fewer height restrictions during installation. Furthermore, easier mold disassembly and automated processes such as cleaning mold residues and casting extraction facilitate mass production. Its disadvantages include... Figure 5 and Figure 7 As shown, in order to prevent the molten metal from entering the mold prematurely, the molten metal must be filled from the lower gate of the mold and die-cast into the cavity installed on the upper part of the mold. This results in an extended flow channel in the die-casting equipment, making it easier for the molten metal to swirl up and have a larger contact area with oxygen, which can easily lead to material contamination and product defects.

[0005] In the existing technology, the above-mentioned vertical vacuum die casting equipment cannot achieve automated cleaning and automated mold removal production due to vacuum pressure holding problems. The vacuum negative pressure time for equipment maintenance and mold replacement is relatively long. During continuous operation, the mold is easily damaged due to residue generated by pouring out the molten material or the edge material of the casting falling off. On the other hand, the traditional horizontal vacuum die casting equipment cannot align the gate with the center of the mold because the molten material needs to be die cast from bottom to top, resulting in the extension of the runner and affecting product quality. The existing technology lacks a die casting device that combines the advantages of both.

[0006] Therefore, existing technologies still need to be improved and developed. Utility Model Content

Detailed Implementation

[0021] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

If the specific posture changes, the directional indicators will also change accordingly.

[0023] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0024] In the existing technology, the above-mentioned vertical vacuum die casting equipment cannot achieve automated cleaning and automated mold removal production due to vacuum pressure holding problems. The vacuum negative pressure time for equipment maintenance and mold replacement is relatively long. During continuous operation, the mold is easily damaged due to residue generated by pouring out the molten material or the edge material of the casting falling off. On the other hand, the traditional horizontal vacuum die casting equipment cannot align the gate with the center of the mold because the molten material needs to be die cast from bottom to top, resulting in the extension of the runner and affecting product quality. The existing technology lacks a die casting device that combines the advantages of both.

[0025] To address the aforementioned problems in the existing technology, this utility model provides a horizontal vacuum die-casting device for amorphous alloys, such as... Figure 1As shown, the horizontal vacuum die casting device for the amorphous alloy includes: an opening and closing mold assembly 300 disposed on a first base 100, the opening and closing mold assembly 300 including a moving mold plate 310, and a vacuum mold 320 detachably disposed on one side of the moving mold plate 310 and driven to move by the moving mold plate 310; a die casting assembly 400 disposed on a second base 200, the die casting assembly 400 including an injection vacuum chamber 410 and a sleeve 411 partially extending out of the injection vacuum chamber 410, and an injection punch 413 slidably disposed inside the sleeve 411; the upper sides of the first base 100 and the second base 200 are adjustablely disposed along the same inclined plane, so that a space for temporarily storing molten molten material is formed between the sleeve 411 and the injection punch 413; a plurality of cavities 322 in the vacuum mold 320 are arranged circumferentially outside the gate 321, and when the vacuum mold 320 presses against the end of the sleeve 411, the gate 321 and the inner hole of the sleeve 411 are tightly connected.

[0026] This invention, by respectively setting the mold opening and closing assembly 300 and the die casting assembly 400 on the first base 100 and the second base 200, allows the vacuum mold 320 to dock with the sleeve 411 through movement. During die casting, the sleeve 411 is kept under vacuum by the injection vacuum chamber 410. After die casting, the vacuum mold 320 can be exposed to the outside by movement, thus facilitating cleaning and automated part removal. Since the first base 100 and the second base 200 are adjusted along the same inclined plane, the inclined angle of the sleeve 411 and the injection punch 413 can form a space for temporary storage of molten metal. Therefore, the vacuum mold 320 can be selected from molds with a circumferential cavity 322 (such as...). Figure 4 As shown in the figure, this invention achieves the effects of reducing the length of the flow channel and improving the quality of die casting. It also has the advantages of existing die casting equipment, enabling fully automated production and facilitating equipment maintenance.

[0027] In the above embodiments, such as Figure 1As shown, the main body of the horizontal vacuum die-casting device for amorphous alloys of this utility model consists of a first base 100, a second base 200, an opening and closing mold assembly 300, and a die-casting assembly 400. The first base 100 and the second base 200 are separately arranged, but the upper surfaces of the first base 100 and the second base 200 should be located in the same plane, so that the opening and closing mold assembly 300 set on the first base 100 and the die-casting assembly 400 set on the second base 200 correspond to each other. In addition, in this embodiment, the first base 100 and the second base 200 are preferably set to be adjustable angle. Even if the upper surfaces of the first base 100 and the second base 200 are kept in the same plane, different tilt angles can be achieved by adjustment. The tilt angle ranges from 5 degrees to 30 degrees, so that the horizontal vacuum die-casting device for amorphous alloys of this utility model can not only be used as a traditional horizontal die-casting equipment, but also form an tilt angle to realize the die-casting process at an angle upward. Based on this structural design, when the upper surfaces of the first base 100 and the second base 200 are in an inclined state, the molten metal can be temporarily stored in the space formed between the sleeve 411 and the injection punch 413 after entering the sleeve 411. At this time, the molten metal is stored with the minimum surface area before die casting, thereby minimizing contamination and avoiding oxidation, temperature drop, or premature entry into the vacuum mold 320 that would lead to a decrease in casting quality.

[0028] Based on the above effects, this utility model is superior to... Figure 5 and Figure 7 The conventional horizontal die-casting equipment shown can utilize a vacuum mold 320 similar to that of conventional vertical die-casting equipment. This vacuum mold 320 features a mold structure with several cavities 322 arranged circumferentially outside the gate 321. During die casting, the molten metal is ejected along the center of the gate 321, reducing the flow distance to each cavity 322 and facilitating the control of feed balance, temperature balance, injection pressure balance, and ejection balance across the cavities 322. Specifically, the main advantage of using a central gate 321 is that, in terms of the symmetry of the impulse and the consistency of the multi-cavity impulse, the improved filling symmetry allows the metal to diffuse outwards from the center, resulting in uniform filling throughout the part and reducing deformation caused by cross-sectional thickness deviations or uneven shrinkage. When the molten metal is divided into multiple cores or zones through consistent filling in the multi-cavity 322, the filling speed and temperature distribution are relatively uniform, contributing to improved quality stability. Even in molds with thin walls or complex geometries, it is easy to centrally control the stamping direction, thereby increasing design freedom. Most importantly, its effectiveness can be verified through simulation and trial operation tests based on the geometric characteristics and quality requirements of the parts, thereby enabling the application of multiple types of molds.

[0029] To achieve the above die-casting process, such as Figure 1As shown, the mold opening and closing assembly 300 includes a movable mold plate 310, which is driven by a driving structure (such as a drive wheel, lead screw, rack, etc.) and can move along a predetermined path. A vacuum mold 320 is detachably mounted on the movable mold plate 310. The vacuum mold 320 is the mold with circumferentially arranged cavities 322, and the gate 321 of the vacuum mold 320 is located at the center of one side of the vacuum mold 320. Correspondingly, the die casting assembly 400 includes an injection vacuum chamber 410, in which a sleeve 411 extends out of the injection vacuum chamber 410. An injection punch 413 is slidably mounted inside the sleeve 411. Since the upper surfaces of the first base 100 and the second base 200 are arranged at a certain inclination angle, such as... Figure 3 As shown, a spoon-shaped structure is formed between the sleeve 411 and the injection punch 413, creating a temporary storage area with minimal surface area after the molten metal enters the sleeve 411. During actual die casting, the moving mold plate 310 is activated, causing the vacuum mold 320 to move to a position that presses against the end of the sleeve 411, forming a tight fit between the two. Simultaneously, the gate 321 of the vacuum mold 320 and the inner hole of the sleeve 411 form a tight fit. Under the vacuum effect of the injection vacuum chamber 410, a vacuum state is formed inside the vacuum mold 320 and the sleeve 411. At this time, opening the injection punch 413 can push the molten metal into the vacuum mold 320, achieving the effect of vacuum die casting.

[0030] In the above embodiments, due to the vacuuming effect of the injection vacuum chamber 410 on the vacuum mold 320 and the sleeve 411, the horizontal vacuum die casting device for amorphous alloys does not require a vacuum cover to be set outside the vacuum mold 320. That is, after the vacuum mold 320 is separated from the sleeve 411, the casting can be directly exposed to the external environment. Based on this feature, the operator can obtain the casting for rapid cooling and clean and maintain the vacuum mold 320. It is even possible to achieve the effect of full automation of the production line by setting up automated machinery in the corresponding position (detailed below).

[0031] Based on the above embodiments, in one possible implementation of this utility model, such as Figure 1 and Figure 2As shown, the die-casting assembly 400 also includes a vacuum melting chamber 420 disposed on one side of the injection vacuum chamber 410. Both the vacuum melting chamber 420 and the injection vacuum chamber 410 have vacuum pressure holding functions and are connected by a vacuum valve 421. In actual use, the vacuum valve 421 can separate the vacuum melting chamber 420 and the injection vacuum chamber 410 into two independent chambers that do not interfere with each other, or it can be controlled to open to connect the vacuum melting chamber 420 and the injection vacuum chamber 410. In actual installation, the vacuum melting chamber 420 is equipped with an automatic soup feeding device 430 for moving the crucible 431. The automatic soup feeding device 430 is specifically a mechanical arm fixedly connected to the crucible 431, and the mechanical arm has telescopic and rotational functions.

[0032] In actual use, when the casting needs to be melted, the vacuum valve 421 is closed, and the vacuum melting chamber 420 is in a vacuum state. After the casting in the crucible 431 is melted into molten liquid, the vacuum mold 320 and the sleeve 411 are connected, and the injection vacuum chamber 410 is evacuated. After the vacuum valve 421 is opened, the crucible 431 containing molten liquid can be passed through the vacuum valve 421 into the injection vacuum chamber 410 by the automatic molten liquid feeding device 430. At this time, the crucible 431 corresponds to a predetermined position on the sleeve 411. The predetermined position has a pre-set opening 412. Molten liquid can enter the sleeve 411 through the opening 412 to achieve the above-mentioned temporary storage and subsequent injection die casting.

[0033] In this embodiment, since the vacuum melting chamber 420 and the injection vacuum chamber 410 are separated by a vacuum valve 421, forming two relatively independent chambers, different operations can be carried out simultaneously in the two chambers without interference during different stages of the die-casting process. For example, in one die-casting process, after the automatic molten metal feeding device 430 finishes pouring the molten metal, it can immediately return to the vacuum melting chamber 420. After closing the vacuum valve 421, the next die-casting process of casting material melting can begin immediately. During this period, the injection vacuum chamber 410 performs the pressing operation of the injection punch 413. The two processes do not interfere with each other and can be carried out simultaneously, thereby greatly improving the die-casting efficiency. At the same time, since both the vacuum melting chamber 420 and the injection vacuum chamber 410 have vacuum pressure holding functions, it can ensure that the casting material and molten metal are in a vacuum environment during melting and die-casting, effectively avoiding oxidation and impurity contamination, and improving the quality of the castings.

[0034] In the above embodiments, such as Figure 2As shown, in order to achieve independent vacuum environment control for the vacuum melting chamber 420 and the injection vacuum chamber 410, the die casting assembly 400 in this embodiment also includes a vacuum pump group 440. The vacuum pump group 440 is connected to the vacuum melting chamber 420 and the injection vacuum chamber 410 through control valves 441 respectively. By opening and closing the control valves 441, the vacuum melting chamber 420 and the injection vacuum chamber 410 can be evacuated independently to meet the vacuum environment requirements of different process stages.

[0035] For example, during the melting stage of the vacuum melting chamber 420, the injection vacuum chamber 410 may be in the stage of opening the vacuum mold 320. Therefore, only the vacuum melting chamber 420 can be evacuated to ensure that the casting is melted in a vacuum environment to avoid oxidation and impurities from entering, while the control valve 441 of the corresponding injection vacuum chamber 410 is closed. During the die casting stage, after the vacuum mold 320 and the sleeve 411 on the outside of the injection vacuum chamber 410 form a sealed connection, the injection vacuum chamber 410 is evacuated by opening the control valve 441 to ensure the vacuum space of the molten metal and the die casting process, while maintaining the vacuum state of the vacuum melting chamber 420 in order to prepare for the next round of melting.

[0036] By adopting the above-described structural design, compared with the existing technology of placing the entire die-casting device inside a vacuum chamber, the technical solution adopted in this application reduces the size of the vacuum chamber and divides it into regions, allowing each region chamber to maintain a vacuum state independently as needed. This avoids the problem of traditional devices spending a lot of time in the operation of releasing and extracting vacuum. This independent control method not only improves the die-casting efficiency but also ensures the quality of the castings.

[0037] In one embodiment of this invention, a baffle (not shown in the figure) is also provided at the opening 412 of the sleeve 411. The baffle can be slidably disposed at the opening 412 by means of a drive rod (hydraulic rod), thereby covering or opening the opening 412 at certain stages. Specifically, after the molten metal has completely entered the sleeve 411, the baffle can be in a covered state. In this state, it can prevent the molten metal from splashing into the injection vacuum chamber 410 along the opening 412 when the injection punch 413 pushes it, thereby avoiding the presence of residual material in the injection vacuum chamber 410. In subsequent steps of the die casting process, the baffle remains in a covered state when the vacuum mold 320 is opened. This is because the vacuum melting chamber 420 may be in the melting stage at this stage. The baffle covering the opening 412 can prevent impurities or air from entering the injection vacuum chamber 410 through the opening 412, thereby preventing impurities from entering the vacuum melting chamber 420 in subsequent operation steps and affecting the melting quality of the casting.

[0038] When the vacuum melting chamber 420 completes melting and the molten metal needs to be transferred to the injection vacuum chamber 410, the baffle slides under the action of the drive rod, opening the opening 412. This allows the crucible 431 containing the molten metal to smoothly pour the molten metal into the sleeve 411 through the opening 412. After the molten metal is poured into the sleeve 411, the baffle slides again to cover the opening 412, preventing molten metal from splashing into the injection vacuum chamber 410 and causing contamination during subsequent die casting. By setting up the baffle, the independence and stability of the vacuum melting chamber 420 and the injection vacuum chamber 410 at different working stages are further ensured, improving the reliability and die casting quality of the entire die casting device.

[0039] In another possible embodiment of this utility model, such as Figure 2 As shown, an automatic feeding device 450 is also provided on one side of the aforementioned vacuum melting chamber 420. This automatic feeding device 450 is used to feed castings into the crucible 431. In specific configurations, the automatic feeding device 450 may include a storage bin and a conveying mechanism. The storage bin is used to store the castings, and the conveying mechanism can accurately and continuously convey the castings from the storage bin into the crucible 431 according to a preset amount. The conveying mechanism can specifically adopt common feeding equipment such as screw conveyors or vibrating feeders. Its conveying speed and feeding amount can be adjusted according to actual production needs. When the automatic feeding device 450 is working, the castings are conveyed from the storage bin to the top of the crucible 431 through the conveying mechanism, and then fall into the crucible 431, realizing the automatic feeding process.

[0040] Meanwhile, the automatic feeding device 450 should include an openable and closable sealing mechanism connected to the vacuum melting chamber 420, such as an openable and closable structure similar to the vacuum valve 421 mentioned above, which works in conjunction with the vacuum pump group 440 to control the vacuum environment during the automatic feeding process. When feeding is required, the openable and closable sealing mechanism is opened, and the control valve 441 of the vacuum pump group 440 corresponding to the vacuum melting chamber 420 is closed. The conveying mechanism accurately conveys the casting material into the crucible 431. After the conveying is completed, the sealing mechanism is immediately closed. At this time, the vacuum pump group 440 opens the control valve 441 corresponding to the vacuum melting chamber 420 to restore the vacuum environment of the vacuum melting chamber 420. By setting up the automatic feeding device 450, the automatic and accurate conveying of the casting material is realized, reducing the tediousness and errors of manual operation, improving production efficiency, and ensuring the vacuum state of the vacuum melting chamber 420 during the feeding process through the cooperation of the openable and closable sealing mechanism and the vacuum pump group 440, which is conducive to ensuring the melting quality of the casting material and further improving the performance and reliability of the entire amorphous alloy horizontal vacuum die casting device.

[0041] In another possible embodiment of this utility model, such as Figure 2As shown, in the aforementioned horizontal vacuum die-casting apparatus for amorphous alloys, a high-frequency heating device 460 is also provided on one side of the crucible 431 within the vacuum melting chamber 420. The high-frequency heating device 460 (also known as a high-frequency induction heating device) is an industrial heating device that utilizes the principle of electromagnetic induction to generate eddy currents inside the metal workpiece, thereby rapidly raising its temperature. The high-frequency heating device 460 generates an alternating magnetic field by having a high-frequency current (usually above 10kHz) flow through the induction coil. When the metal workpiece is placed in this magnetic field, eddy currents are induced inside it. Due to the resistance, the eddy currents generate Joule heat, causing the workpiece to heat up rapidly. In this embodiment, the high-frequency heating device 460 is positioned within the vacuum melting chamber 420 and close to the crucible 431. When it is necessary to melt the casting material in the crucible 431, the high-frequency heating device 460 is activated. The high-frequency current flows through the induction coil to generate an alternating magnetic field. The casting material in the crucible 431, as the metal workpiece, induces eddy currents in the alternating magnetic field, thereby rapidly heating up and melting to form a molten metal. This heating method has the advantages of fast heating speed and uniform heating, which can melt the casting into a molten soup that meets the requirements in a short time, greatly improving the melting efficiency.

[0042] Furthermore, since the heating and melting are carried out in a vacuum environment, oxidation reactions of the castings due to contact with air during the melting process are effectively avoided, ensuring the purity of the molten metal and guaranteeing high-quality die casting in the future. Simultaneously, the power of the high-frequency heating device 460 can be flexibly adjusted according to actual melting requirements. For example, it can be specifically adjusted based on the metal material or quantity of the molten metal to accommodate different types and quantities of castings, further enhancing the controllability and flexibility of the melting process. In addition, during the melting process, the temperature of the molten metal in the crucible 431 can be monitored in real time by a temperature sensor, and the temperature signal is fed back to the control system. The control system automatically adjusts the power of the high-frequency heating device 460 according to preset temperature parameters, achieving precise control of the melting temperature. The cooperation between the high-frequency heating device 460 and the temperature control system provides ideal melting conditions for horizontal vacuum die casting of amorphous alloys, contributing to improved overall performance and quality stability of the castings.

[0043] In another possible embodiment of this utility model, such as Figure 1 and Figure 2As shown, to ensure the accuracy of the docking between the vacuum mold 320 and the sleeve 411, the opening and closing mold assembly 300 also includes a plurality of tie rods 330 spaced at predetermined intervals and arranged circumferentially. The tie rods 330 are positioned on the side facing the die-casting assembly 400, and their ends are fixedly mounted on the outer shell of the injection vacuum chamber 410 and fixedly connected to the outer shell of the injection vacuum chamber 410. Specifically, the sleeve 411 that extends through the injection vacuum chamber 410 is located at the center of the tie rods, thereby corresponding to the movable template 310 that is slidably connected to the tie rods 330. A driving structure is provided on the movable template 310, which is used to drive the movable template carrying the vacuum mold 320. The moving mold 310 moves along the direction of the set points 330 and eventually docks or separates from the end of the sleeve 411. Because the moving mold 330 is spaced at predetermined distances and is set around the circumference, it provides a stable guide for the movement of the moving mold 310, ensuring that the vacuum mold 320 will not deviate during the movement. This ensures the accuracy of docking between the vacuum mold 320 and the sleeve 411, which not only improves the stability of the die casting process, but also reduces die casting defects caused by inaccurate docking and improves the quality of the castings. At the same time, it also further enhances the structural strength of the entire die casting device, enabling it to withstand greater die casting pressure and impact, and further improves the reliability and service life of the die casting device.

[0044] Furthermore, to ensure the airtightness of the vacuum mold 320 on the moving template 310 when it is connected to the end of the sleeve 411, such as Figure 1 and Figure 2 As shown, a fitting part 415 adapted to the shape of the vacuum mold 320 is also provided on the outer shell of the aforementioned injection vacuum chamber 410. The fitting part 415 is made of rigid material, and an injection hole adapted to the inner hole of the sleeve 411 is provided at its center. One end of the sleeve 411 that protrudes from the injection vacuum chamber 410 is fitted into the fitting part 415 to form a fixed connection. The injection hole has the same diameter as the inner hole of the sleeve 411 and is tightly connected. In the actual die casting process, it is used as part of the channel for the injection punch 413 to squeeze the molten molten material. One end of the fitting part 415 corresponding to the vacuum mold 320 is a flat surface, or a fitting structure adapted to the end face of the vacuum mold 320. In actual installation, a sealing element can also be provided on the end face of the mating part 415 corresponding to the vacuum mold 320. The sealing element can be made of elastic sealing material such as rubber. When the vacuum mold 320 presses against the mating part 415, the sealing element is squeezed and deformed, so that the gap between the mating part 415 and the vacuum component is sealed.

[0045] The fitting part 415 and the sealing part are installed at the end of the vacuum mold 320 and the fitting part 415 to form a good airtight environment. On the one hand, it can effectively prevent air leakage in the injection vacuum chamber 410 during the vacuuming process, ensure the stability of the vacuum environment, and thus ensure that the die casting process is carried out under ideal vacuum conditions, avoiding the oxidation of the molten metal or the generation of impurities due to air mixing, which would affect the quality of the casting. On the other hand, it can ensure flexible contact between the vacuum mold 320 and the fitting part 415 to prevent damage to the vacuum mold 320 due to rigid contact.

[0046] In another possible embodiment of this utility model, such as Figure 1 and 2 As shown, the aforementioned injection punch 413 is driven by an injection rod 414, which is fixedly connected to the side of the injection punch 413 facing away from the vacuum mold 320 and is arranged along the central axis of the sleeve 411. The other end of the injection rod 414 is connected to the injection hydraulic circuit mechanism 470 and the energy storage device 471 provided on the injection hydraulic circuit mechanism 470. The injection hydraulic circuit mechanism 470 drives the injection rod 414 to reciprocate by controlling the flow of hydraulic oil, thereby driving the injection punch 413 to move linearly within the sleeve 411. The energy storage device 471 serves to store and release energy. When the injection punch 413 pushes the molten metal, the energy storage device 471 can quickly release the stored energy to provide a strong thrust for the injection punch 413, ensuring that the molten metal can be injected into the vacuum mold 320 with sufficient pressure and speed to achieve high-quality die casting. Meanwhile, the injection hydraulic circuit mechanism 470 is also equipped with precise control valves and sensors, which can monitor and adjust the movement speed and pressure of the injection rod 414 in real time to meet the needs of different die-casting processes. This drive system, consisting of the injection rod 414, the injection hydraulic circuit mechanism 470, and the energy storage device 471, has advantages such as fast response speed, high control accuracy, and large thrust, which can significantly improve the die-casting efficiency and casting quality of amorphous alloy horizontal vacuum die-casting equipment.

[0047] Based on the above embodiments, due to the vacuum effect of the injection vacuum chamber 410 on the vacuum mold 320 and the sleeve 411, the horizontal vacuum die casting device for amorphous alloys does not require a vacuum cover to be set outside the vacuum mold 320. That is, after the vacuum mold 320 is separated from the sleeve 411, the casting can be directly exposed to the external environment. Based on this feature, this embodiment also provides an automatic clamping device 490 on one side of the connection between the moving mold plate 310 and the sleeve 411. The automatic clamping device 490 can be specifically configured as a robotic arm, and the end of the robotic arm is equipped with a clamp that can accurately clamp the casting. The clamp is adapted to the shape and size of the casting. When the vacuum mold 320 is separated from the sleeve 411 and the casting is exposed to the external environment, the control system controls the automatic clamping device 490 to move precisely to the position of the casting and use the clamp to firmly extract the casting. Subsequently, the automatic clamping device 490 moves the casting to the cooler according to a predetermined route, cools the casting for several seconds, and then transfers it to a pre-set conveyor belt for product inspection. The automatic clamping device 490 automates the entire process from die casting completion to subsequent processing, reducing the time and labor intensity of manual casting handling and improving production efficiency. Furthermore, this automated processing method can be integrated with other automated components of the die casting unit to form a complete and efficient horizontal vacuum die casting production line for amorphous alloys, significantly enhancing the intelligence level and overall efficiency of the entire production process.

[0048] Furthermore, in this embodiment, an automatic spraying device 480 is also provided on the outer shell of the injection vacuum chamber 410. The nozzle of the automatic spraying device 480 corresponds to the position of the vacuum mold 320. The nozzle of the automatic spraying device 480 is used to spray a predetermined liquid to remove foreign matter and contaminants from the mold surface. In the specific working process, after the vacuum mold 320 completes one die casting and separates from the sleeve 411, the shaped casting located in the vacuum mold 320 is obtained by the automatic clamping device 490. Then the automatic spraying device 480 is activated, and its nozzle sprays the liquid evenly onto the surface of the vacuum mold 320 according to a preset program. This liquid can quickly dissolve and remove the metal debris remaining on the mold surface and other contaminants attached during the die casting process, effectively cleaning the mold surface. Due to the high temperature generated during the die casting process, the sprayed liquid absorbs heat and evaporates after the debris is removed by the impact force, eliminating the need for secondary cleaning by the staff. By setting up an automatic spraying device 480, not only is the workload and labor intensity of manual mold cleaning reduced and production efficiency improved, but the mold is also guaranteed to be clean before each die casting, which helps to improve the surface quality of the castings and reduce die casting defects caused by foreign matter on the mold surface.

[0049] Based on the above embodiments, the actual working process of the horizontal vacuum die-casting device for amorphous alloys of this utility model is as follows: First, start the automatic feeding device 450 to accurately and continuously feed the casting material into the crucible 431 according to the preset amount. After the feeding is completed, the sealing mechanism can be closed, and the vacuum pump group 440 opens the control valve 441 of the corresponding part of the vacuum melting chamber 420 to keep the vacuum melting chamber 420 in a vacuum environment.

[0050] Next, the high-frequency heating device 460 is turned on. The high-frequency current flows through the induction coil to generate an alternating magnetic field. The casting material in the crucible 431 is induced to generate eddy currents and rapidly heats up to melt and form a molten liquid. During the melting process, the temperature sensor monitors the temperature of the molten liquid in real time and feeds the signal back to the control system. The control system automatically adjusts the power of the high-frequency heating device 460 according to the preset parameters to achieve precise control of the melting temperature.

[0051] Once the molten metal reaches the appropriate state, the moving template 310 moves along the guide column 330 under the action of the driving structure, so that the vacuum mold 320 and the end of the sleeve 411 are accurately aligned. At this time, the mating parts 415 and the sealing parts ensure good airtightness at the alignment point. Then, the control valve 441 is opened to evacuate the injection vacuum chamber 410, while maintaining the vacuum melting chamber 420 in a vacuum state. After the vacuum valve 421 between the injection vacuum chamber 410 and the vacuum melting chamber 420 is opened, the baffle on the sleeve 411 is driven to open, and the crucible 431 containing the molten metal pours the molten metal into the sleeve 411 through the opening 412. After pouring, the baffle slides again to cover the opening 412, the crucible 431 returns to the vacuum melting chamber 421 and the vacuum valve 421 is closed. At this time, the material melting for the next die casting can be carried out in the vacuum melting chamber 420.

[0052] Then, the injection hydraulic circuit mechanism 470 controls the flow of hydraulic oil to drive the injection rod 414 to move, which in turn drives the injection punch 413 to make linear motion in the sleeve 411. The energy storage device 471 rapidly releases energy when the injection punch 413 pushes the molten liquid, providing a strong thrust to the injection punch 413 and injecting the molten liquid into the vacuum mold 320 with sufficient pressure and speed.

[0053] After die casting is completed, the moving mold 310, carrying the vacuum mold 320, separates from the sleeve 411. The automatic clamping device 490 precisely moves to the location of the casting, firmly lifts the casting using clamps, moves it to a cooler to cool for a few seconds, and then transfers it to a preset conveyor belt for product inspection. At the same time, the automatic spraying device 480 is activated, and the nozzle evenly sprays liquid chemicals onto the surface of the vacuum mold 320 to remove foreign matter and contaminants from the mold surface. After the liquid chemicals absorb heat and evaporate, the mold is cleaned, preparing it for the next die casting.

[0054] In the aforementioned working process, thanks to the separate setup of the mold opening and closing assembly 300 and the die casting assembly 400, the entire process from feeding to final product output can be automatically controlled without human intervention for cleaning, maintenance, or part removal; thanks to the independent vacuum setup of the injection vacuum chamber 410 and the vacuum melting chamber 420, the melting process and the die casting process are realized in independent cavities, and a seamless process cycle can be achieved; thanks to the adjustable tilting setup of the first base 100 and the second base 200, the angle of the sleeve 411 and the injection punch 4 can be used to adjust the angle of the sleeve 411 and the injection punch 410. 13 can form a temporary storage space for molten molten material. Therefore, a vacuum mold 320 with a circumferential cavity 322 can be selected for die casting. This type of vacuum mold 320 is different from the mold used in traditional horizontal vacuum die casting equipment. It has the advantages of shortening the flow channel, avoiding the problem of molten molten material rolling up and causing a large contact area with oxygen when flowing, and can effectively reduce the occurrence of porosity, impurities, and deep flow marks on the product surface. It can be seen that the horizontal vacuum die casting equipment for amorphous alloys of this utility model can not only realize automation and improve production efficiency, but also improve product quality.

[0055] In summary, this utility model provides a horizontal vacuum die-casting device for amorphous alloys. The horizontal vacuum die-casting device for amorphous alloys includes: an opening and closing mold assembly disposed on a first base, the opening and closing mold assembly including a moving mold plate, and a vacuum mold that is driven to move by the moving mold plate detachably disposed on one side of the moving mold plate; a die-casting assembly disposed on a second base, the die-casting assembly including an injection vacuum chamber and a sleeve partially extending out of the injection vacuum chamber, and an injection punch slidably disposed inside the sleeve; the upper sides of the first base and the second base are adjustablely disposed along the same inclined plane, so that a space for temporarily storing molten molten material is formed between the sleeve and the injection punch; a plurality of cavities in the vacuum mold are arranged circumferentially outside the gate, and when the vacuum mold presses against the end of the sleeve, the gate and the inner hole of the sleeve are tightly connected. This invention sets the mold opening and closing assembly and the die casting assembly on the first base and the second base respectively, so that the vacuum mold can be moved to dock with the sleeve. During die casting, the sleeve is kept under vacuum by the injection vacuum chamber. After die casting, the vacuum mold can be moved to expose the outside, which facilitates cleaning and automated part removal. Since the first base and the second base are adjusted along the same inclined plane, the inclined angle of the sleeve and the injection punch can form a space for temporary storage of molten molten material. Therefore, the vacuum mold can be selected with a circumferential cavity, which can reduce the length of the flow channel and improve the quality of die casting. This invention combines the advantages of existing die casting equipment, can realize fully automated production, and is easy to maintain.

[0056] It should be understood that the application of this utility model is not limited to the examples above.
