Description

Technical Field

[0001] This invention relates to the field of metal die casting, and in particular to a segmented die casting equipment with continuous feeding. Background Technology

[0002] Die casting is a metal casting process, also known as die casting. Essentially, it is a method of obtaining metal castings by filling a die casting cavity with liquid or semi-liquid metal at a high speed under high pressure, and then shaping and solidifying it under pressure.

[0003] In traditional technology, die casting equipment mainly includes a molten metal structure, an injection structure, and a mold-closing structure. The mold-closing structure is used to install the mold, and the molten metal structure is usually a furnace used to melt the metal raw materials. During die casting production, a robotic arm equipped with a casting ladle takes the molten metal from the furnace and pours it into the injection structure. The injection structure then injects the molten metal into the mold of the mold-closing structure to form the shape. This type of die casting equipment is easily contaminated by air or impurities in the environment during the process of conveying the molten metal, resulting in insufficient density of the die-cast metal castings and low die casting quality. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a segmented die-casting equipment with continuous material feeding, in which the melting, slurry preparation, and injection processes are continuous and reliable, the die-casting efficiency is high, and the material feeding space is isolated from the outside environment, resulting in high die-casting quality.

[0005] A segmented die-casting apparatus with continuous feeding according to an embodiment of the present invention includes:

[0006] The mold clamping assembly includes a machine base, a mold clamping drive module, a mold clamping base, a movable base, and a fixed base. The mold clamping base and the fixed base are both connected to the machine base, the movable base is slidably connected to the machine base, and the mold clamping drive module is connected to the mold clamping base and the movable base.

[0007] The die-casting assembly includes an extrusion drive mechanism, a screw drive mechanism, an injection drive mechanism, a heater, and a first barrel, a flow divider module, a second barrel, a third barrel, and a fourth barrel connected in sequence. The first barrel, the flow divider module, and the second barrel are all located on a horizontal axis on one side of the mold clamping assembly. The fourth barrel is connected to the fixed base on the side away from the movable base. Heaters are provided on the outside of the first barrel, the second barrel, and the fourth barrel. The first barrel has a feeding port. An extrusion push rod is slidably connected in the first barrel and is connected to the extrusion drive mechanism. The flow divider module has several flow divider channels. A spiral agitator is rotatably connected in the second barrel and is connected to the screw drive mechanism. An injection push rod is slidably connected in the fourth barrel and is connected to the injection drive mechanism.

[0008] In this embodiment, the first barrel, the flow divider module, and the second barrel are all located above the mold closing assembly, and the third barrel is perpendicular to the horizontal plane.

[0009] In this embodiment, a steering connector is connected between the second and third material cylinders. The steering connector has an arc-shaped steering channel, and the screw drive mechanism is located on the side of the steering connector away from the second material cylinder.

[0010] In this embodiment, the length of the fourth barrel is less than the length of the injection push rod.

[0011] In this embodiment, an ultrasonic vibrator is provided inside the third feed cylinder.

[0012] In this embodiment, a heater is provided outside the third feed cylinder.

[0013] In this embodiment, a guide cylinder is connected to the end of the fourth material cylinder away from the fixed base, and the injection push rod is also slidably connected in the guide cylinder. A heater is provided outside the guide cylinder.

[0014] In this embodiment, the injection drive mechanism is a hydraulic cylinder, and the hydraulic cylinder is connected to a hydraulic accumulator.

[0015] In this embodiment, the heater is an electromagnetic heating coil.

[0016] In this embodiment, the mold closing drive module includes an opening and closing drive mechanism, an active block, and two sets of telescopic arm mechanisms. The opening and closing drive mechanism is connected to the mold closing base, the active block is connected to the opening and closing drive mechanism, and the two sets of telescopic arm mechanisms are located on opposite sides of the active block. The telescopic arm mechanism includes a first swing arm, a second swing arm, and a three-axis arm. The two ends of the first swing arm are rotatably connected to one end of the active block and one end of the three-axis arm, respectively. The two ends of the second swing arm are rotatably connected to the other end of the three-axis arm of the movable seat, and the three-axis arm is rotatably connected to the other end of the fixed seat.

[0017] The embodiments of the present invention have at least the following beneficial effects:

[0018] The multi-stage structure separates the melting, semi-solid slurry preparation, and injection casting processes. Each feeding action can be carried out in a closed and continuous space, avoiding contamination from air or impurities in the environment and effectively ensuring the purity of the molten metal used for die casting. This significantly improves the quality of the die-cast parts, and the synergistic continuous feeding effect effectively increases die-casting production efficiency. By installing independent heaters in the first, second, and fourth barrels, the temperature required for different processes can be independently controlled. This provides high temperature control flexibility, energy efficiency, and environmental friendliness, and effectively improves the melting, slurry preparation, and injection effects, thereby significantly improving die-casting quality. A spiral agitator is used to agitate the molten metal in the second barrel. Stirring and slurry preparation allows the molten metal to form a spherical crystal structure, effectively reducing the formation of porosity and segregation. This improves the density of the final die-cast metal casting. Furthermore, the diversion module disperses and diffuses the molten metal, enhancing the uniformity of its distribution in the second barrel and preventing unmelted material from entering. This extends the lifespan of the spiral agitator and ensures high reliability and safety in the stirring and slurry preparation process. The parallel arrangement of the molten metal preparation sections for the mold-closing and die-casting components effectively controls the overall dimensions of the equipment in a single dimension, facilitating transportation and installation.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0032] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0033] Die casting, also known as die casting, is a metal casting process. Essentially, it involves filling a die-casting cavity with liquid or semi-liquid metal at high speed under high pressure, and then shaping and solidifying it to obtain a metal casting. Traditionally, die casting equipment mainly consists of a melting structure, an injection structure, and a mold-closing structure. The mold-closing structure is used to install the mold, while the melting structure is typically a furnace for melting the metal raw materials. During die casting, a robotic arm equipped with a casting ladle removes the molten metal from the furnace and pours it into the injection structure. The injection structure then injects the molten metal into the mold of the mold-closing structure. This type of die casting equipment, where the melting structure is separate from the injection structure, is easily contaminated by air or impurities in the environment during the molten metal transport process. This results in insufficient density in the die-cast metal parts, with obvious and dense sand pores, leading to low die-casting quality.

[0034] Furthermore, this type of die-casting equipment has a slow production cycle, making it difficult to meet the demands of large-scale manufacturing. Moreover, this melting method relies solely on furnace heating, resulting in a significant temperature gradient in the molten metal. Inconsistent temperature and fluidity between different batches of molten metal make it difficult to ensure the consistency of each die-cast part, making quality control challenging. In some technologies, the molten metal is transferred to an ultrasonic pulping machine for pulping after melting. However, this transfer process exposes the metal to ambient air, leading to secondary contamination. Additionally, the loading and unloading actions of the robotic arm equipped with the casting spoon are performed in the open air, posing safety risks and further reducing production efficiency.

[0035] The following is for reference only. Figure 1 To be continued Figure 6 This invention describes a segmented die-casting equipment with continuous material feeding, which features continuous and reliable melting, slurry preparation, and injection processes, high die-casting efficiency, and a material feeding space that is isolated from the outside world, resulting in high die-casting quality.

[0036] Reference Figures 1 to 6 This embodiment of a segmented die-casting equipment with continuous material feeding includes:

[0037] The mold clamping assembly 100 includes a machine base 110, a mold clamping drive module 120, a toggle module, and a mold clamping base 130, a movable base 140, and a fixed base 150 arranged sequentially along a horizontal axis. Specifically, the mold clamping base 130, the movable base 140, and the fixed base 150 are arranged sequentially along the y-axis. Preferably, the movable base 140 connects the mold clamping base 130 and the fixed base 150 through a guide mechanism, which can effectively improve the reliability of the mold opening and closing action driven by the movable base 140. The guide mechanism can be a combination of guide pillars and guide sleeves. The base 150 is fixedly connected to the machine base 110, and the movable base 140 is slidably connected to the machine base 110. The movable base 140 and the fixed base 150 are used to install the die casting mold. The two ends of the toggle module are respectively connected to the mold closing base 130 and the movable base 140. The fixed end of the mold closing drive module 120 is connected to the mold closing base 130, and the movable base 140 is connected to the movable end of the mold closing drive module 120. The mold closing drive module 120 is used to drive the movable base 140 to translate relative to the fixed base 150 along the y-axis direction, thereby realizing the opening and closing action of the die casting mold.

[0038] The die-casting assembly 200 includes an extrusion drive mechanism 210, a screw drive mechanism 220, an injection drive mechanism 230, a heater 240, and a first barrel 250, a flow divider module 260, a second barrel 270, a third barrel 280, and a fourth barrel 290 connected in sequence. The extrusion drive mechanism 210, the screw drive mechanism 220, and the injection drive mechanism 230 are all connected to the machine base 110. Multiple heaters 240 are provided. The first barrel 250, the flow divider module 260, and the second barrel 270 are all located on one side of the mold clamping assembly 100 along the horizontal axis, specifically distributed along the y-axis direction. This effectively controls the overall dimensions of the equipment in a single dimension, effectively reducing transportation and installation limitations. Furthermore, the first barrel 250, the second barrel 270, and the fourth barrel 290... All barrels 290 extend along the y-axis. The fourth barrel 290 is connected to the fixed base 150 on the side away from the movable base 140. The fourth barrel 290 is horizontally set, specifically parallel to the y-axis. By setting the fourth barrel 290 coaxially with the mold opening and closing direction, the overall structural stability of the equipment can be effectively improved, avoiding radial offset during the injection casting process, and effectively improving the stability of the die casting action. Each of the first barrel 250, the second barrel 270, and the fourth barrel 290 is equipped with a corresponding heater 240. According to different production processes, the barrels of different processes are set with different heating temperatures. The first barrel 250 is provided with a feeding port 251. An extrusion push rod 211 is slidably connected in the first barrel 250. The extrusion push rod 211 is connected to... The extrusion drive mechanism 210 drives the extrusion pusher 211 to slide along the y-axis in the first cylinder 250, so that the molten metal fed from the feeding port 251 and melted is conveyed through the diversion module 260 to the second cylinder 270. The extrusion drive mechanism 210 is located outside the end of the first cylinder 250 away from the second cylinder 270. The diversion module 260 is provided with several radially distributed diversion channels 261. The two ends of the diversion channels 261 are respectively connected to the first channel of the first cylinder 250 and the second channel of the second cylinder 270. The diversion channels 261 can effectively ensure the melting effect of the molten metal passing through the diversion module 260, providing a good foundation for subsequent stirring and slurry preparation. The second cylinder 270 is rotatably connected to... A spiral agitator 221 is connected to a spiral drive mechanism 220. The spiral drive mechanism 220 drives the spiral agitator 221 to rotate around the y-axis in the second barrel 270 to agitate and transport the molten metal towards the third barrel 280. The spiral agitator 221 agitates and slurries the molten metal in the second barrel 270 to form a semi-solid molten metal, which improves the quality of die casting. The spiral drive mechanism 220 is located outside the end of the second barrel 270 away from the first barrel 250. A pressure injection push rod 231 is slidably connected in the fourth barrel 290 and is connected to the pressure injection drive mechanism 230. The pressure injection drive mechanism 230 drives the pressure injection push rod 231 to slide along the fourth barrel 290.This allows the semi-solid molten metal to be transported from the metal barrel to the cavity of the die-casting mold connected to the fixed base 150.

[0039] The multi-stage structure separates the melting, semi-solid propagation, and injection casting processes. Each action can be performed in a closed and continuous space, which not only avoids contamination from air or impurities in the environment but also effectively ensures the purity of the molten metal used for die casting, thus improving the quality of the die-cast parts. Furthermore, the synergistic and continuous feeding effect significantly improves die casting production efficiency. By installing independent heaters 240 in the first barrel 250, the second barrel 270, and the fourth barrel 290, the temperature required for different processes can be independently controlled. The temperature control is highly flexible. The melting temperature of the first barrel 250 is set to 650℃~700℃, the slurry temperature of the second barrel 270 is set to 600℃~620℃, and the injection temperature of the fourth barrel 290 is 580℃~600℃. This effectively reduces the maximum temperature required in the die-casting process, saving energy and protecting the environment. It also effectively improves the melting, slurry preparation, and injection effects. Furthermore, the heater 240 outside the fourth barrel 290 effectively ensures the fluidity of the molten metal being injected, thereby effectively improving the die-casting quality. (The last sentence appears to be incomplete and possibly refers to a specific feature or mechanism.) The rotary stirring paddle 221 agitates and slurries the molten metal in the second barrel 270, enabling the molten metal to form a spherical crystal structure with a grain size of less than 50 micrometers. This effectively reduces the formation of porosity and segregation, thus improving the density of the final die-cast metal casting and reducing sand hole defects. Furthermore, the flow distribution module 260 diverts and diffuses the molten metal, effectively improving the uniformity of the molten metal distribution in the second barrel 270 and preventing some of the molten metal from melting completely. The material enters the second feed cylinder 270, which can avoid local overheating or cold material inclusion, and can provide an excellent processing foundation for subsequent pulping processes. In particular, it can effectively handle the reliable melting and diversion of rod-shaped metal raw materials, which can not only effectively extend the service life of the spiral agitator 221, but also ensure high reliability and safety of the pulping process. By distributing the molten material pulping sections of the mold assembly 100 and the die-casting assembly 200 in a side-by-side manner, the overall size of the equipment in a single dimension can be effectively controlled, which can effectively facilitate transportation and installation.

[0040] In the initial state, reference Figure 4As shown, the extrusion pusher 211 is located on the side of the feeding port 251 opposite to the diversion module 260. Metal raw materials are fed into the first material cylinder 250 from the feeding port 251. The heater 240 outside the first material cylinder 250 heats and melts the metal raw materials. The extrusion drive mechanism 210 drives the extrusion pusher 211 to extrude the molten metal in the first material cylinder 250. After being diverted by the diversion module 260, the molten metal enters the second material cylinder 270 evenly. The injection drive mechanism 230 drives the injection pusher 231 to inject the molten metal in the fourth material cylinder 290 into the third material cylinder 280. (Reference) Figure 5 The image shows the die-casting process after the die-casting mold has been installed and closed.

[0041] By coaxially arranging the mold clamping assembly 100 and the fourth material cylinder 290 for injection, vibration during injection can be effectively reduced, the service life of the overall equipment can be effectively extended, and the stability of the mold opening and closing action can be effectively improved.

[0042] It should be noted that the first barrel 250 is also equipped with a descaling port, which is used to add refining agent, which can remove impurities and hydrogen from the molten metal, thereby effectively improving the purity of the molten metal and improving the quality of die casting.

[0043] Understandably, the first material cylinder 250, the diversion module 260, and the second material cylinder 270 are all located above the mold clamping assembly 100, adopting a vertical stacking layout. This effectively reduces the footprint of the equipment, thereby reducing land costs during installation and application. It can effectively reduce the width of the equipment by more than 30%, and can effectively adapt to most production environments where the factory has sufficient height but limited floor space. The third material cylinder 280 is perpendicular to the horizontal plane. The use of the vertically set third material cylinder 280 in conjunction with the spiral stirring paddle 221 can effectively improve the smoothness of metal molten material conveying and also effectively reduce conveying energy consumption.

[0044] Understandably, a steering connector 271 connects the second barrel 270 and the third barrel 280. The steering connector 271 has an arc-shaped steering channel 272, with its two ends connected to the second channel of the second barrel 270 and the third channel of the third barrel 280, respectively. The arc-shaped steering channel 272 effectively improves the smoothness of molten metal transport. The screw drive mechanism 220 is located on the side of the steering connector 271 away from the second barrel 270. One end of the screw agitator 221 passes through the steering connector 271 and connects to the screw drive mechanism 220. The steering connector 271 also has a high-temperature resistant sealed bearing connected to one end of the screw agitator 221. The sealed bearing has a temperature resistance greater than 800℃, ensuring the transmission stability of the screw agitator 221 while preventing molten metal leakage. This effectively improves the transmission stability of the screw agitator 221. Furthermore, the inner wall of the steering channel 272 is polished, which effectively reduces deceleration during the molten metal steering process.

[0045] The third feed cylinder 280 is set vertically to the horizontal plane. Its vertical layout works in conjunction with the spiral agitator 221 to form a forced downward conveying mechanism, which can effectively overcome the problem of slowed flow of molten metal due to viscosity changes. The vertical feed cylinder design, combined with the axial thrust of the spiral agitator 221, significantly improves the conveying speed of the semi-solid slurry and avoids the stratification of molten metal.

[0046] It is understandable that the length of the fourth material cylinder 290 is less than the length of the injection push rod 231. Specifically, the length of the fourth material cylinder 290 from the position connecting the third material cylinder 280 to the position connecting the fixed seat 150 is L1, and the length of the injection push rod 231 is L2, where L2>L1.

[0047] After complete injection, when the injection push rod 231 reaches the injection endpoint, the injection push rod 231 blocks the interface connecting the third barrel 280 and the fourth barrel 290, forming a mechanical trap. (Refer to...) Figure 5 and Figure 6 As shown, this design effectively prevents the backflow of excess material and effectively blocks excess molten metal from entering the fourth barrel 290. In addition, this structural design allows the molten material preparation process in the front section to operate asynchronously with the cooling and demolding process in the back section. That is, the process before the fourth barrel 290 can be independent of the subsequent cooling, forming and demolding actions, which can effectively improve the overall die casting production efficiency.

[0048] It is understood that an ultrasonic vibrator 281 is provided inside the third material cylinder 280. The ultrasonic vibrator 281 is used to break up the dendrites of the molten metal in the third material cylinder 280, thereby further preparing the molten metal into a semi-solid pulp. Preferably, the vibrating part of the ultrasonic vibrator 281 extends into the interior of the third material cylinder 280 and is separated from the inner wall of the third material cylinder 280, which can effectively reduce the vibration of the third material cylinder 280 and extend the service life of the overall structure. The ultrasonic vibrator is a high-temperature resistant ultrasonic vibrating rod, which can adapt to a temperature of up to 800°C, with a frequency of about 20kHz and an amplitude of 3~20 micrometers.

[0049] It is understandable that the heater 240 outside the first material cylinder 250 is located on the side of the feeding port 251 near the diversion module 260. After the metal raw material is fed into the first material cylinder 250 from the feeding port 251, the extrusion drive mechanism 210 drives the extrusion push rod 211 to send the metal raw material to the working area near the heater 240. The heat generated by the heater 240 can effectively act on the metal raw material, which can effectively improve the energy utilization rate.

[0050] Specifically, a corresponding heater 240 is also provided outside the third barrel 280. The heater 240 outside the third barrel 280 can effectively ensure the slurry preparation effect of the molten metal in the third barrel 280, and at the same time ensure the fluidity of the molten metal in the third barrel 280. By carrying out secondary melting and semi-solid slurry preparation in the third barrel 280, the proportion of spheroidal crystal structure in the molten metal can be further increased, which can further improve the die casting effect.

[0051] Understandably, the end of the fourth material cylinder 290 away from the fixed seat 150 is connected to the guide cylinder 291, and the injection push rod 231 is also slidably connected in the guide cylinder 291. A corresponding heater 240 is also provided outside the guide cylinder 291. The heater 240 outside the guide cylinder 291 can preheat and keep the injection push rod 231 warm, thereby improving the fluidity of the molten metal during injection and preventing the molten metal in contact with the injection push rod 231 from partially solidifying in the guide cylinder 291 due to temperature difference. This can effectively ensure the reliability of the die casting production operation.

[0052] It is understandable that the injection drive mechanism 230 is a hydraulic cylinder, which is connected to a hydraulic accumulator 232. By enhancing the die-casting force of the injection push rod 231 through the hydraulic accumulator 232 in the last step of the molten metal flow, the density of the die casting can be effectively improved.

[0053] The hydraulic accumulator 232 can provide instantaneous pressure boost when the injection push rod 231 reaches near the injection endpoint, thereby effectively increasing the die-casting pressure and thus improving the die-casting effect.

[0054] It is understood that heater 240 is an electromagnetic heating coil. The electromagnetic heating coil heats the material in the corresponding tube through electromagnetic induction. Using an alternating magnetic field for heating effectively improves the utilization rate of thermal energy. Compared to traditional ceramic heating coils, for the same heating effect, the electromagnetic heating coil can reduce energy consumption by 50%, and its heating speed is faster, effectively reducing die-casting production time and thus improving production efficiency. Preferably, the surfaces of the first tube 250, second tube 270, third tube 280, and fourth tube 290 are all covered with an insulation layer. This insulation layer effectively reduces heat loss, thereby improving energy utilization and effectively saving die-casting costs.

[0055] It is understood that the mold closing drive module 120 includes an opening and closing drive mechanism 121, an active block 122, and two sets of telescopic arm mechanisms. The opening and closing drive mechanism 121 is connected to the mold closing base 130, and the active block 122 is connected to the opening and closing drive mechanism 121. The opening and closing drive mechanism 121 is used to drive the active block 122 to move closer to or further away from the fixed base 150 along the y-axis direction. Preferably, the active block 122 is connected to the fixed base 150 and / or the movable base 140 through a guide structure, which can effectively improve the reliability of the translational movement of the active block 122. The guiding structure can be a combination of guide pillars and guide sleeves. Two sets of telescopic arm mechanisms are located on opposite sides of the active block 122. Each telescopic arm mechanism includes a first swing arm 123, a second swing arm 124, and a three-axis arm 125. The two ends of the first swing arm 123 are rotatably connected to one end of the active block 122 and one end of the three-axis arm 125, respectively. The two ends of the second swing arm 124 are rotatably connected to the other end of the three-axis arm 125 on the movable seat 140, and the three-axis arm 125 is rotatably connected to the other end of the fixed seat 150. During mold opening and material removal, the opening and closing drive mechanism 121 drives the movable seat 140 away from the fixed seat 150 via the active block 122 and the two sets of telescopic arm mechanisms, thereby enabling the die-casting mold between the movable seat 140 and the fixed seat 150 to open and remove material. For specific structural details, refer to [reference needed]. Figure 6 As shown.

[0056] The telescopic arm mechanism, which links the double swing arm and the three-axis arm 125, can improve the stability of the mold closing action through geometric optimization. Furthermore, the symmetrical arrangement of the two sets of telescopic arm mechanisms completely cancels out the lateral torque, thereby effectively reducing the parallelism error of the movable seat 140.

[0057] Preferably, the extrusion drive mechanism 210 and the opening and closing drive mechanism 121 can be configured as linear drive modules such as hydraulic cylinders, and the screw drive mechanism 220 can be configured as a structure capable of outputting rotational drive force such as a hydraulic motor.

[0058] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
