[0022] Die casting is a metal casting process, also known as die casting. In essence, it is a method of obtaining metal castings by filling the die casting cavity with liquid or semi-liquid metal at a high speed under high pressure, and then forming and solidifying it under pressure. In traditional technology, die casting equipment mainly includes a melt structure, an injection structure and a clamping structure. The clamping structure is used to install the mold. The melt structure is usually a furnace for melting metal raw materials. During die casting production, a robotic arm equipped with a casting spoon takes the molten metal from the furnace and pours it into the injection structure. The injection structure then presses the molten metal into the mold of the clamping structure for molding. This die casting equipment with a melt structure separated from the injection structure is easily contaminated by air or impurities in the environment during the process of conveying the molten metal, resulting in insufficient density of the metal castings obtained by die casting, obvious and dense sand holes, and low die casting quality.
[0023] Furthermore, this type of die-casting equipment suffers from a slow production cycle, making it difficult to meet high-volume manufacturing needs. Furthermore, this method of melting the metal solely through furnace heating results in significant temperature gradients in the molten metal. The temperature and fluidity of the molten metal removed from different batches are inconsistent, making it difficult to ensure the consistency of each die-cast metal casting and controlling die-casting quality. Some technologies involve transferring the melted metal to an ultrasonic pulping machine for pulping. However, this transfer process exposes the metal to further ambient air and secondary contamination. Furthermore, the robotic arm equipped with the casting spoon performs its pick-and-place operations in an exposed environment, leading to safety issues and a further reduction in production efficiency.
[0024] The following is the attached Figure 1 To the attached Figure 6 , describing the continuous feeding segmented die-casting equipment of the embodiment of the present invention, the melting, slurrying and injection processes are continuous and reliable, the die-casting efficiency is high, and the feeding space is isolated from the outside world, and the die-casting quality is high.
[0025] Reference Figures 1 to 6 , a continuous feeding segmented die casting device of this embodiment includes: The mold clamping assembly 100 includes a machine 110, a mold clamping drive module 120, an elbow module, and a mold clamping base 130, a movable base 140, and a fixed base 150 arranged in sequence along the horizontal axis. The mold clamping base 130, the movable base 140, and the fixed base 150 are specifically arranged in sequence along the y-axis. Preferably, the movable base 140 is connected to 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 structure composed of a guide column and a guide sleeve. The mold clamping base 130 and the fixed base 150 are connected to each other. The seats 150 are fixedly connected to the machine platform 110, and the movable seat 140 is slidably connected to the machine platform 110. The movable seat 140 and the fixed seat 150 are used to install the die-casting mold. The two ends of the toggle module are respectively connected to the mold clamping seat 130 and the movable seat 140. The fixed end of the mold clamping drive module 120 is connected to the mold clamping seat 130, and the movable seat 140 is connected to the movable end of the mold clamping drive module 120. The mold clamping drive module 120 is used to drive the movable seat 140 to translate relative to the fixed seat 150 along the y-axis direction, thereby realizing the opening and closing of the die-casting mold; 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 diverter 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 110. There are multiple heaters 240. The first barrel 250, the diverter module 260, and the second barrel 270 are all located on the horizontal axis of one side of the clamping assembly 100, specifically distributed along the y-axis direction, which can effectively control the size of the overall equipment in a single dimension and effectively reduce the restrictions on transportation and installation. The first barrel 250, the second barrel 270, and the fourth barrel 290 are all connected to the machine 110. The barrels 290 all extend in the y-axis direction, and the fourth barrel 290 is connected to the side of the fixed seat 150 away from the movable seat 140. The fourth barrel 290 is arranged horizontally, specifically parallel to the y-axis. By coaxially arranging the opening and closing directions of the mold between the fourth barrel 290 and the clamping die, the structural stability of the overall equipment can be effectively improved, and radial deviation during the injection molding process can be avoided, which can effectively improve the stability of the die-casting action. A corresponding heater 240 is provided outside the first barrel 250, the second barrel 270 and the fourth barrel 290. According to different production processes, the barrels of different processes are set to different heating temperatures. The first barrel 250 is provided with a feeding port 251, and an extrusion push rod 211 is slidably connected to the first barrel 250. The extrusion push rod 211 is connected In the extrusion drive mechanism 210, the extrusion drive mechanism 210 is used to drive the extrusion push rod 211 to slide along the y-axis direction in the first barrel 250, so that the metal melt fed from the feeding port 251 and melted is transported to the second barrel 270 through the diversion module 260. The extrusion drive mechanism 210 is located outside the end of the first barrel 250 away from the second barrel 270. The diversion module 260 is provided with a plurality of radially distributed diversion channels 261. The two ends of the diversion channel 261 are respectively connected to the first channel of the first barrel 250 and the second channel of the second barrel 270. The diversion channel 261 can effectively ensure the melting effect of the metal melt passing through the diversion module 260, providing a good foundation for subsequent stirring and slurrying. The second barrel 270 is rotated to connect There is a spiral stirring paddle 221, which is connected to the spiral driving mechanism 220. The spiral driving mechanism 220 is used to drive the spiral stirring paddle 221 to rotate around the y-axis in the second barrel 270 to stir and convey the molten metal to the third barrel 280. The spiral stirring paddle 221 stirs and slurries the molten metal in the second barrel 270 by stirring to form a semi-solid molten metal, which can improve the quality of die-casting. The spiral driving mechanism 220 is located outside the end of the second barrel 270 away from the first barrel 250. The fourth barrel 290 is slidably connected to the injection push rod 231, which is connected to the injection driving mechanism 230. The injection driving mechanism 230 is used to drive the injection push rod 231 to slide along the fourth barrel 290.So that the semi-solid molten metal is transported from the metal barrel to the cavity of the die-casting mold connected to the fixed seat 150.
[0026] The multi-stage structure is used to respectively carry out melting, semi-solid paddle making and injection casting, and each action can be carried out in a closed and continuous space, which can not only avoid pollution such as air or impurities in the environment, but also effectively ensure the purity of the metal melt used for die casting, effectively improve the quality of metal castings obtained by die casting, and the coordinated continuous feeding effect can effectively improve the die casting production efficiency; by respectively arranging 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, among which the melt 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℃, which can effectively reduce the maximum temperature required for the die-casting process, save energy and protect the environment, and can effectively improve the effects of melt, slurry and injection, and the heater 240 outside the fourth barrel 290 can effectively ensure the fluidity of the metal melt of the injection object, thereby effectively improving the die-casting quality; through the screw The stirring blade 221 stirs the molten metal in the second barrel 270 to form a slurry, which can form a spherical crystal structure in the molten metal, and the grain size is less than 50 microns, thereby effectively reducing the formation of pores and segregation, and effectively improving the density of the metal castings obtained by the final die casting, and effectively reducing the formation of sand hole defects. In addition, the shunting module 260 is used to divert and diffuse the molten metal, which can not only effectively improve the uniformity of the distribution of the molten metal entering the second barrel 270, but also effectively block the part that has not been effectively melted. When the material enters the second barrel 270, it can avoid local overheating or cold material inclusion, and can provide an excellent processing basis for the subsequent slurrying process, especially it can effectively cope with the reliable melting and diversion of rod-shaped metal raw materials, which can not only effectively extend the service life of the spiral stirring paddle 221, but also have high reliability and safety performance in stirring and slurrying; by distributing the molten material slurrying parts of the mold assembly 100 and the die-casting assembly 200 side by side, the size of the overall equipment in a single dimension can be effectively controlled, which can effectively facilitate transportation and installation applications.
[0027] In the initial state, refer to Figure 4As shown, the extrusion push rod 211 is located on the side of the feeding port 251 away from the diversion module 260, and the metal raw material is fed into the first barrel 250 from the feeding port 251; the heater 240 outside the first barrel 250 heats and melts the metal raw material, and the extrusion drive mechanism 210 drives the extrusion push rod 211 to squeeze the metal melt in the first barrel 250 and then evenly enter the second barrel 270 after being diverted by the diversion module 260. The injection drive mechanism 230 drives the injection push rod 231 to inject the metal melt in the fourth barrel 290 into the third barrel 280. Figure 5 The figure shows the state of die casting after the die casting mold is installed and clamped.
[0028] By coaxially arranging the mold clamping assembly 100 and the fourth barrel 290 for injection, vibration during injection can be effectively reduced, the service life of the entire equipment can be effectively extended, and the stability of the mold opening and closing actions can be effectively improved.
[0029] It should be noted that the first barrel 250 is also provided with a material removal port, which is used to add a refining agent to remove impurities and hydrogen in the molten metal, thereby effectively improving the purity of the molten metal and improving the quality of die-casting molding.
[0030] It can be understood that the first barrel 250, the diversion module 260 and the second barrel 270 are all located above the mold assembly 100, and adopt a vertical stacking layout, which can effectively reduce the floor space of the equipment, thereby reducing the land cost during installation and application, and can effectively reduce the width of the equipment by more than 30%. It can effectively adapt to the production environment where most factories have sufficient height but limited ground space. The third barrel 280 is perpendicular to the horizontal plane. The use of the vertically arranged third barrel 280 in conjunction with the spiral stirring paddle 221 can effectively improve the smoothness of the metal melt transportation and effectively reduce the transportation energy consumption.
[0031] It is understood that a diverting connector 271 is connected between the second barrel 270 and the third barrel 280. The diverting connector 271 is provided with an arc-shaped diverting channel 272, the ends of which are connected to the second channel of the second barrel 270 and the third channel of the third barrel 280, respectively. The arc-shaped diverting channel 272 effectively improves the smoothness of molten metal conveyance. The screw drive mechanism 220 is located on the side of the diverting connector 271 away from the second barrel 270. One end of the spiral stirring paddle 221 passes through the diverting connector 271 and is connected to the screw drive mechanism 220. The diverting connector 271 also has a high-temperature resistant sealed bearing connected to the outside of one end of the spiral stirring paddle 221. The sealed bearing has a temperature resistance of greater than 800°C, ensuring the transmission stability of the spiral stirring paddle 221 while preventing molten metal leakage. This effectively improves the transmission stability of the spiral stirring paddle 221. The polished inner wall of the diverting channel 272 effectively reduces the deceleration of the molten metal during the diverting process.
[0032] The third barrel 280 is arranged perpendicular to the horizontal plane. Its vertical layout cooperates with the spiral stirring paddle 221 to form a forced downward conveying mechanism, which can effectively overcome the flow slowdown problem of the molten metal caused by the change in viscosity; the vertical barrel design cooperates with the axial thrust of the spiral stirring paddle 221 to significantly improve the conveying speed of the semi-solid slurry and avoid the occurrence of stratification of the molten metal.
[0033] It can be understood that the length of the fourth barrel 290 is smaller than the length of the injection push rod 231. Specifically, the length of the fourth barrel 290 from the position connected to the third barrel 280 to the position connected to the fixing seat 150 is L1, and the length of the injection push rod 231 is L2, L2>L1.
[0034] After the complete injection, that is, when the injection push rod 231 reaches the injection end point, the injection push rod 231 blocks the interface connecting the third barrel 280 and the fourth barrel 290, forming a mechanical interception. Figure 5 and Figure 6 As shown, it can effectively prevent the residual material from flowing back and can effectively block the excess metal melt from entering the fourth barrel 290; in addition, this structural design can also make the front section of the melt slurrying process and the rear section of the cooling and demolding process run asynchronously, that is, the process before the fourth barrel 290 can be independent of the subsequent cooling molding and mold opening and demolding actions, which can effectively improve the overall die-casting production efficiency.
[0035] It can be understood that an ultrasonic vibrator 281 is provided in the third barrel 280. The ultrasonic vibrator 281 is used to shatter the dendrites of the molten metal in the third barrel 280, thereby further performing semi-solid slurrying on the molten metal. Preferably, the vibrating part of the ultrasonic vibrator 281 extends into the interior of the third barrel 280 and is separated from the inner wall of the third barrel 280, which can effectively reduce the vibration of the third barrel 280 and extend the service life of the overall structure. The ultrasonic vibrator is a high-temperature resistant ultrasonic vibrator rod that can adapt to a temperature of up to 800°C, has a frequency of approximately 20kHz, and an amplitude of 3 to 20 microns.
[0036] It can be understood that the heater 240 outside the first barrel 250 is located on the side of the feeding port 251 close to the diversion module 260. After the metal raw material is fed into the first barrel 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 close to 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.
[0037] Specifically, a corresponding heater 240 is also provided outside the third barrel 280. This heater 240 effectively ensures the slurrying effect of the molten metal in the third barrel 280 and also ensures the fluidity of the molten metal in the third barrel 280. By performing secondary melting and semi-solidification slurrying in the third barrel 280, the proportion of spherulites in the molten metal can be further increased, further improving the die-casting effect.
[0038] It can be understood that the end of the fourth barrel 290 away from the fixed seat 150 is connected to the guide cylinder 291, and the injection push rod 231 is also slidably connected to 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, avoiding partial solidification of the molten metal that contacts the injection push rod 231 in the guide cylinder 291 due to temperature difference, and effectively ensuring the reliability of the die-casting production action.
[0039] It can be understood 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 metal melt flow, the density of the die-casting can be effectively improved.
[0040] The hydraulic accumulator 232 can provide instantaneous pressure increase when the injection push rod 231 reaches the vicinity of the injection end point, thereby effectively increasing the die-casting pressure and further improving the die-casting effect.
[0041] It is understood that the heater 240 is an electromagnetic heating coil, which heats the material in the corresponding material tube by electromagnetic induction. The use of an alternating magnetic field for heating can effectively improve the utilization rate of thermal energy. Compared with the ceramic heating coil in traditional technology, the electromagnetic heating coil can reduce the power consumption by 50% for the same heating effect. The electromagnetic heating coil also heats faster, which can effectively shorten the die-casting production time and thus improve production efficiency. Preferably, the surfaces of the first barrel 250, the second barrel 270, the third barrel 280 and the fourth barrel 290 are all covered with an insulation layer. The insulation layer can effectively reduce heat loss, thereby improving energy utilization and effectively saving die-casting costs.
[0042] It can be understood that the mold clamping 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 clamping 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 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 action of the active block 122. The guide structure can be a structure composed of a guide column and a guide sleeve, and the two sets of telescopic arm mechanisms are respectively located on opposite sides of the active block 122; for each set of telescopic arm mechanisms, the telescopic arm mechanism includes a first swing arm 123, a second swing arm 124 and a three-axis arm 125, and the two ends of the first swing arm 123 are respectively rotatably connected to the active block 122 and one end of the three-axis arm 125, and the two ends of the second swing arm 124 are respectively rotatably connected to the other end of the three-axis arm 125 of the movable seat 140, and the three-axis arm 125 is rotatably connected to the other end of the fixed seat 150. When the mold is opened and the material is removed, the opening and closing drive mechanism 121 drives the movable seat 140 to move away from the fixed seat 150 through the active block 122 and the two sets of telescopic arm mechanisms, so that the die-casting mold between the movable seat 140 and the fixed seat 150 can realize the mold opening and material removal. For the specific structural state, refer to Figure 6 shown.
[0043] The telescopic arm mechanism linked by the double swing arm and the three-axis arm 125 can improve the stability of the mold closing action through geometric optimization, and the symmetrical arrangement of the two sets of telescopic arm mechanisms completely offsets the lateral torque, thereby effectively reducing the parallelism error of the movable seat 140.
[0044] 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 a rotational drive force such as a hydraulic motor.
[0045] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
