Description

Technical Field

[0001] The present invention relates to the technical field of die casting, and more particularly to an aluminum alloy die casting device and method thereof. Background Art

[0002] Die casting is a method of obtaining castings by filling the die cavity with liquid or semi-liquid metal at high speed under high pressure and rapidly solidifying it under pressure. The die casting mold used is called a die casting mold. The design quality and manufacturing quality of the die casting mold directly determine the shape and precision of the casting, surface requirements and internal quality, and the smoothness of production operations. Therefore, the die casting mold plays an important role in production.

[0003] A Chinese patent document (CN116652151A) discloses a self-adjusting aluminum alloy die-casting device. The device is described in the specification as comprising a frame, a first die base, and a second die base. The first die base and the second die base are both arranged on the frame. A static die is arranged on the first die base, and a movable die is arranged on the second die base. A sealed chamber with a variable volume is formed between the movable die and the second die base. When the molds are closed, the static die and the movable die abut against each other, and a die-casting chamber and an air storage chamber are formed between the static die and the movable die. An injection hole is provided on the first die base, and metal liquid is introduced into the die-casting chamber through the injection hole. On the one hand, the die-casting cavity gradually expands and eventually presents the shape of the casting. At the same time, the gas in the die-casting cavity is squeezed by the metal liquid and discharged into the gas storage cavity; on the other hand, the volume of the sealed chamber gradually decreases, which gradually increases the pressure in the sealed chamber, thereby gradually increasing the extrusion force of the movable mold on the casting, making it easier for the metal liquid to fill the entire die-casting cavity, improving the exhaust effect and thus improving the quality of the casting. However, in actual use, it is difficult to effectively clean the aluminum alloy molten residue remaining inside, resulting in difficulty in ensuring the processing quality of aluminum alloy die-castings.

[0004] In the production process of aluminum alloy die-castings, although a robotic arm is used to efficiently remove the castings, it is still difficult to completely avoid the problem of molten slag being retained in the mold. These slags are mainly composed of impurities, oxides and other substances in the molten metal that are difficult to completely melt. They will stubbornly adhere to the inside of the mold or penetrate into the surface layer and even the internal structure of the die-casting. These stubborn residues pose a serious threat to the performance of the die-castings. They not only weaken the strength and corrosion resistance of the die-castings, making the castings more susceptible to damage when subjected to external forces or harsh environments, but may also cause a series of quality problems during the subsequent molten metal injection process. The slag may cause the newly injected molten metal to flow poorly, thereby forming burrs on the edge of the casting, or causing deformation of the entire casting, seriously affecting the processing accuracy and overall appearance of the aluminum alloy castings. More seriously, these quality problems not only reduce the market competitiveness of the products, but may also pose a potential threat to the safety and service life of the castings. In view of this, we propose an aluminum alloy die-casting device and method thereof. Summary of the Invention

The other end of the elastic telescopic rod is fixedly connected to the nut. The position of the tooth of the card corresponds to the position of the card slot.

[0016] A method for using an aluminum alloy die-casting device includes the following steps: S1. After the casting is processed, the casting is removed by an external robotic arm, and the motor is automatically started; S2. The motor pushes the outer cylinder assembly and the cleaning assembly downward to complete the cleaning of the inside of the die-casting mold; S3. After the cleaning is completed, the motor runs in the reverse direction to drive the outer cylinder assembly to reset for subsequent casting processing.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. By designing the cleaning assembly, the inner cylinder assembly, the outer cylinder assembly and the adjustment assembly, during cleaning, the motor will automatically be in a high-speed running state. At this time, both the inner cylinder assembly and the outer cylinder assembly rotate at high speed, while the adjustment assembly will be locked due to the centrifugal force during high-speed rotation, so that the outer cylinder assembly gradually moves downward during high-speed rotation. When it moves downward a certain distance, the pressure assembly will also discharge low-temperature liquid from the inner cylinder assembly to the outer cylinder assembly. As the outer cylinder assembly rotates and discharges, at this time, the cleaning assembly will also clean the die-casting mold. When the outer cylinder assembly moves downward a certain distance and the cleaning assembly is located on one side of the die-casting mold, the motor automatically adjusts the speed and switches to a low-speed rotation state. At this time, the adjustment assembly is difficult to lock due to insufficient centrifugal force, and the outer cylinder assembly remains in place and rotates on its own, so that the device can quickly adjust the cleaning position just by starting during use, and continuously clean the required parts at a low speed after adjusting to the specified position. Compared with the existing liquid flushing method, the device not only increases its discharge efficiency by rotating when discharging liquid, but also drives the cleaning assembly to clean the die-casting mold when the outer cylinder assembly operates, further ensuring the cleaning effect of the device, avoiding the situation of residues in the die-casting mold, and ensuring the quality of the castings for subsequent processing.

[0018] 2. The present invention also designs an adjustment component, an outer cylinder component and an inner cylinder component. When running at high speed, the motor drives the inner cylinder and the outer cylinder to rotate through the rotating shaft. At this time, the outer cylinder drives the nut to rotate at high speed. When the nut rotates at high speed, the counterweight pulls the guide block to slide in the guide groove. While the elastic telescopic rod extends, it pushes the engaging tooth to be engaged with the card slot. At this time, the card slot is docked with the card slot to lock the nut, and the nut is in a static state. The outer cylinder rotating at high speed will quickly move downward through the thread on its surface. When moving a certain distance, the motor automatically switches to low-speed operation. At this time, the centrifugal force of the counterweight is insufficient to continue pulling the elastic telescopic rod, and the elastic telescopic rod will pull the engaging tooth out of the card slot under the action of its own elastic force. At this time, the outer cylinder will drive the nut to rotate during the rotation process without moving up and down, and complete the cleaning of the die-casting mold while rotating. Since the position of the die-casting mold is fixed, therefore, there is no need to adjust the operation of the motor. After the outer cylinder rotates and moves a fixed distance, the motor will automatically switch, reducing the cost of numerical control operation and the operation difficulty of personnel, improving the popularization of the device. With the up and down movement and in-situ rotation of the cleaning brush, the cleaning effect of the device is guaranteed to the greatest extent.

[0019] 3. The present invention also designs an inner cylinder component, a pressure component and an outer cylinder component. When the outer cylinder moves downward, the liquid injection machine injects liquid into the inner cylinder through the limit collar, so that the liquid accumulates in the flow holes in the inner cylinder. When the sealing block moves downward and disengages from the sealing hole, a large amount of liquid will flow upward along the diversion groove and be discharged through the through holes outside the outer cylinder during the flow process. On the one hand, by continuously discharging the liquid, the temperature of the mold surface is reduced, and the cleaning brush and the die-casting mold can be cleaned synchronously during the flushing process, avoiding the influence of impurity residues on the cleaning effect. At the same time, the liquid can be evenly sprayed on the surface of the die-casting mold to achieve the effect of coating the die-casting mold and reducing the difficulty of subsequent demoulding.

[0022] As Figures 1 to 8 shown, an aluminum alloy die-casting device and method thereof according to the present invention include a die-casting machine cabin 102, a die-casting mold 103 and a drive assembly 104, and further include The die-casting mechanism 1 includes a machine body base 101, a die-casting machine cabin 102 connected to the machine body base 101, a driving component 104, and a die-casting mold 103. Among them, the die-casting mold 103 is connected to the driving component 104; and, the cleaning mechanism 2 includes a support component 201, a rotating component 204 connected to the support component 201, an inner cylinder component 205 located below the rotating component 204, a pressure component 202 and an outer cylinder component 206 connected to the inner cylinder component 205, an adjusting component 207, and a cleaning component 208. Among them, the outer cylinder component 206 is located outside the inner cylinder component 205, the adjusting component 207 is located outside the outer cylinder component 206, the adjusting component 207 is connected to the support component 201, and the cleaning component 208 is located at the bottom of the outer cylinder component 206. By designing the cleaning component 208, the inner cylinder component 205, the outer cylinder component 206, and the adjusting component 207, during cleaning, the motor 203 will automatically be in a high-speed operation state. At this time, both the inner cylinder component 205 and the outer cylinder component 206 rotate at high speed, while the adjusting component 207 will be locked due to the centrifugal force during high-speed rotation, causing the outer cylinder component 206 to gradually move downward during high-speed rotation. When it moves downward a certain distance, the pressure component 202 will also discharge low-temperature liquid from the inner cylinder component 205 to the outer cylinder component 206. As the outer cylinder component 206 rotates and discharges, at this time, the cleaning component 208 will also clean the die-casting mold 103. When the outer cylinder component 206 moves downward a certain distance and the cleaning component 208 is located on one side of the die-casting mold 103, the motor 203 automatically adjusts the speed and switches to a low-speed rotation state. At this time, the adjusting component 207 is difficult to lock due to insufficient centrifugal force, and the outer cylinder component 206 remains in place and rotates self-rotationally, enabling the device to quickly adjust the cleaning position just by starting during use, and continuously cleaning the required part at a low speed after adjusting to the specified position. Compared with the existing liquid flushing method, this device not only increases its discharge efficiency by rotating during liquid discharge, but also drives the cleaning component 208 to clean the die-casting mold 103 when the outer cylinder component 206 operates, further ensuring the cleaning effect of the device, avoiding the occurrence of residues in the die-casting mold 103, and ensuring the quality of the castings in subsequent processing.

[0023] In an embodiment of the present invention, the upper part of the body base 101 is fixedly connected to the bottom of the die-casting cabin 102 and the driving assembly 104 respectively. One side of the driving assembly 104 is fixedly connected to the die-casting mold 103. The upper part of the supporting assembly 201 is clamped with the rotating assembly 204. The top end of the rotating assembly 204 is drivingly connected to the motor 203. The motor 203 is fixedly connected above the supporting assembly 201. The bottom end of the rotating assembly 204 is fixedly connected to the inner cylinder assembly 205. The inner cylinder assembly 205 is communicated with the pressure assembly 202. The outer wall of the inner cylinder assembly 205 abuts against the inner wall of the outer cylinder assembly 206. The outer cylinder assembly 206 is threadedly connected to the inner wall of the adjusting assembly 207. The top end of the adjusting assembly 207 is fixedly connected to the lower part of the supporting assembly 201. The cleaning assembly 208 is fixedly connected to the bottom of the outer cylinder assembly 206. The pressure assembly 202 and the supporting assembly 201 are both fixedly connected above the die-casting cabin 102. The supporting assembly 201 includes a bracket 2011. A top plate 2012 is fixedly connected above the bracket 2011. A reinforcing rib 2013 is fixedly connected below the top plate 2012. The other end of the reinforcing rib 2013 is fixedly connected to one side of the bracket 2011. The lower part of the bracket 2011 is fixedly connected to the upper part of the die-casting cabin 102. The top plate 2012 is clamped with the rotating assembly 204 above. The motor 203 is fixedly connected above the top plate 2012. By designing the adjusting assembly 207, the outer cylinder assembly 206 and the inner cylinder assembly 205, when running at high speed, the motor 203 will drive the inner cylinder 2051 and the outer cylinder 2061 to rotate through the rotating shaft 2041. At this time, the outer cylinder 2061 will drive the nut 2073 to rotate at high speed. When the nut 2073 rotates at high speed, the counterweight 20795 will pull the guiding block 20791 to slide in the guiding groove 2075. While the elastic telescopic rod 20792 extends, it pushes the engaging tooth 20796 to engage into the engaging groove 2078. At this time, the engaging groove 2078 is docked with the engaging groove 2078 to lock the nut 2073, and the nut 2073 is in a stationary state. The high-speed rotating outer cylinder 2061 will quickly move downward through the thread 2063 on its surface. When moving a certain distance, the motor 203 automatically switches to low-speed operation. At this time, the centrifugal force of the counterweight 20795 is insufficient to continue pulling the elastic telescopic rod 20792. The elastic telescopic rod 20792 will pull the engaging tooth 20796 out of the engaging groove 2078 under the action of its own elastic force. At this time, the outer cylinder 2061 will drive the nut 2073 to rotate during the rotation process without moving up and down, and complete the cleaning of the die-casting mold 103 while rotating. Since the position of the die-casting mold 103 is fixed, therefore, it is not necessary to adjust the operation of the motor 203. After the outer cylinder 2061 rotates and moves a fixed distance, the motor 203 will automatically switch, reducing the cost of numerical control operation and the operation difficulty of personnel, and improving the popularization of the device. With the up and down movement and in-situ rotation of the cleaning brush 2082, the cleaning effect of the device is maximally guaranteed.

[0024] In an embodiment of the present invention, the pressure assembly 202 includes a liquid injector 2021. One side of the liquid injector 2021 is fixedly connected to a conduit 2022.

The upper part of the inner cylinder 2051 is fixedly connected to the bottom end of the rotating shaft 2041. By designing the inner cylinder assembly 205, the pressure assembly 202, and the outer cylinder assembly 206, when the outer cylinder 2061 moves downward, the liquid injector 2021 will inject liquid into the inner cylinder 2051 through the limit collar 2023, causing the liquid to accumulate within the circulation hole 2054 of the inner cylinder 2051. When the sealing block 2065 moves downward and disengages from the sealing hole 2057, a large amount of liquid will flow upward along the diversion groove 2055 and be discharged through the through holes 2064 outside the outer cylinder 2061 during the flow process. On the one hand, by continuously discharging the liquid, the temperature of the mold surface is reduced. During the flushing process, the cleaning brush 2082 and the die casting mold 103 can be cleaned simultaneously, avoiding the influence of impurity residue on the cleaning effect. At the same time, the liquid can be evenly sprayed on the surface of the die casting mold 103 to achieve the effect of coating the die casting mold 103 and reducing the difficulty of subsequent demolding.

A number of limiting rods 2062 are fixedly connected inside the outer cylinder 2061. A thread 2063 is provided outside the outer cylinder 2061. A number of through holes 2064 are formed in the outer cylinder 2061. A sealing block 2065 is fixedly connected to the lower part of the inner wall of the outer cylinder 2061.

A number of guiding grooves 2075 are formed outside the nut 2073, and a number of limiters 2079 are slidably connected in the guiding grooves 2075. The installation sleeve 2071 is fixedly connected to the lower part of the top plate 2012 through the positioning columns 2072. The nut 2073 is threadedly connected to the outer cylinder 2061. By providing a diversion groove 2055 outside the inner cylinder 2051 and adopting a spiral design for the diversion groove 2055, when the liquid enters between the inner cylinder 2051 and the outer cylinder 2061, the liquid can be discharged along the diversion groove 2055 instead of accumulating in the space at the bottom of the inner cylinder 2051 and the inner bottom of the outer cylinder 2061, ensuring that the liquid can be quickly discharged when the outer cylinder 2061 moves to the side of the die-casting mold 103, thereby ensuring the cooling and cleaning efficiency of the device; By providing a limiting card slot 2052 outside the inner cylinder 2051 and clamping the limiting card sleeve 2023 in the limiting card slot 2052, while ensuring the stable rotation of the inner cylinder 2051, the connection effect between the liquid injection machine 2021 and the inner cylinder 2051 is ensured, ensuring that the liquid can be stably injected into the inner cylinder 2051 and improving the operating stability of the device.

[0026] As another embodiment of the present invention, the cleaning component 208 includes a mounting ring 2081. Above the mounting ring 2081, a plurality of cleaning brushes 2082 are fixedly connected. Below the mounting ring 2081, it is fixedly connected to the lower part of the outer cylinder 2061 through a plurality of frames. The mounting ring 2081 is located outside the outer cylinder 2061. The limiter 2079 includes two guiding blocks 20791. On one side of the two guiding blocks 20791, two elastic telescopic rods 20792 are fixedly connected. Between the two guiding blocks 20791, two connecting rods 20793 are fixedly connected. The connecting rod 20793 is fixedly connected to the tooth 20796 through a connecting block 20794. On both sides of the tooth 20796, counterweight blocks 20795 are fixedly connected. The guiding block 20791 is slidably connected in the guiding groove 2075. The other end of the elastic telescopic rod 20792 is fixedly connected to the nut 2073. The position of the tooth 20796 corresponds to the position of the card slot 2078. Due to the setting of the counterweight block 20795, when the outer cylinder 2061 drives the nut 2073 to rotate at high speed, the counterweight block 20795 can stably push the tooth 20796 to be docked with the card slot 2078. When running at low speed, the centrifugal force is insufficient to push the counterweight block 20795 to move.

[0027] Working principle: This embodiment provides an aluminum alloy die-casting device and its method. When in use, the motor 203 will automatically be in a high-speed running state. At this time, both the inner cylinder assembly 205 and the outer cylinder assembly 206 rotate at high speed, and the adjusting assembly 207 will be locked due to the centrifugal force during high-speed rotation, causing the outer cylinder assembly 206 to gradually move downward during high-speed rotation. When it moves downward a certain distance, the pressure assembly 202 will also discharge low-temperature liquid from the inner cylinder assembly 205 to the outer cylinder assembly 206. As the outer cylinder assembly 206 rotates and discharges, at this time, the cleaning component 208 will also clean the die-casting mold 103. When the outer cylinder assembly 206 moves downward a certain distance and the cleaning component 208 is located on one side of the die-casting mold 103, the motor 203 automatically adjusts the speed and switches to a low-speed rotation state. At this time, the adjusting assembly 207 is difficult to be locked due to insufficient centrifugal force, and the outer cylinder assembly 206 remains in place and rotates by itself; When running at high speed, the motor 203 drives the inner cylinder 2051 and the outer cylinder 2061 to rotate through the rotating shaft 2041. At this time, the outer cylinder 2061 drives the nut 2073 to rotate at high speed. When the nut 2073 rotates at high speed, the counterweight 20795 pulls the guide block 20791 to slide in the guide groove 2075. While the elastic telescopic rod 20792 extends, it pushes the engaging tooth 20796 to engage into the card slot 2078. At this time, the card slot 2078 is docked with the card slot 2078 to lock the nut 2073, and the nut 2073 is in a stationary state. The high-speed rotating outer cylinder 2061 will quickly move downward through the thread 2063 on its surface. When it moves a certain distance, the motor 203 automatically switches to low-speed operation. At this time, the centrifugal force of the counterweight 20795 is insufficient to continue pulling the elastic telescopic rod 20792, and the elastic telescopic rod 20792 will pull the engaging tooth 20796 out of the card slot 2078 under the action of its own elastic force. At this time, the outer cylinder 2061 will drive the nut 2073 to rotate during the rotation process without moving up and down, and complete the cleaning of the die-casting mold 103 while rotating; When the outer cylinder 2061 moves downward, the liquid injection machine 2021 injects liquid into the inner cylinder 2051 through the limit collar 2023, causing the liquid to accumulate in the flow holes 2054 in the inner cylinder 2051. When the sealing block 2065 moves downward and disengages from the sealing hole 2057, a large amount of liquid will flow upward along the diversion groove 2055 and be discharged through the through holes 2064 outside the outer cylinder 2061 during the flow process.
