Technical Field

[0001] The invention relates to the technical field of in-mold automatic feeding, in particular to an in-mold automatic feeding device. Background Art

[0002] The die-casting process is a metal casting process. It is a precision casting method that uses high pressure to force molten metal into a complex-shaped metal mold. Under the action of high pressure, the molten metal can quickly fill the mold cavity, which can meet the production of some high-precision and complex-shaped parts. The die-casting process requires solid raw materials to be fed into the device, so an automatic feeding device is required.

[0003] A patent with the announcement number CN110280737B discloses an automatic feeding die-casting device, including a base, two feeding box brackets are fixed on the left side of the base, a feeding box is fixed on the upper side of the two feeding box brackets, a feeding wheel is installed at the lower side discharge port of the feeding box, a first pulley is installed on the side of the feeding wheel, a feeding plate is arranged on the lower side of the feeding wheel, a high-temperature solution is installed inside the high-temperature furnace, a die-casting cylinder is embedded inside the high-temperature solution, a feed pipe is connected to the left side of the die-casting cylinder, a receiving hopper is installed at the other end of the feed pipe, a piston is embedded inside the die-casting cylinder, a pressure column is connected to the upper end of the piston, racks are fixed on both sides of the pressure column, a gear fixing plate is slidably connected to the pressure column, a motor is also installed on the top fixing frame, a discharge pipe is connected to the right side of the die-casting cylinder, a molding frame is connected to the right side of the discharge pipe, a lower mold is fixed at the bottom of the molding frame, an upper mold is arranged on the upper side of the lower mold, and the upper mold is slidably connected to the molding frame. The automatic feeding die-casting device is easy to use and has high die-casting efficiency.

[0004] However, since the existing automatic feeding die-casting device cannot control the discharge amount of solid materials, if too much solid material is discharged, the melting time of the material will be prolonged, which will lead to a long production time. Injecting too much slurry will cause an extra part of the molded parts to require secondary processing and removal, while discharging too little material will cause the molded parts to be missing corners. In addition, when using, after the solid material is put into the receiving hopper and the receiving pipe, it is necessary to wait for it to melt before the die-casting process can be carried out. Multiple batches of materials cannot be melted at the same time, resulting in slow production speed and serious impact on production efficiency.

The cavity 43 is an opening connected to the No. 1 material guide cavity 42. After the material enters the No. 1 material guide cavity 42, it will enter one of the No. 2 material guide cavities 43 under the guidance of the two material guide plates 45, and the material guide plates 45 are rotated around the rotating shaft 44 to adjust the angles of the two material guide plates 45.

[0049] like Figure 2 In the embodiment, the upper rotating disk 13 rotates and fits the top of the discharge assembly 1, so that the upper rotating disk 13 fits the top of the protective tank 11 and rotates to prevent the material from entering between the protective tank 11 and the upper rotating disk 13 and causing the material to be stuck. Figure 3 and Figure 4 In the embodiment, two limiting rib grooves 1401 are vertically provided on the inner wall of the sliding sleeve 14, and two limiting ribs 1402 are provided on the side curved surface of the transmission shaft 12 to engage with the limiting rib grooves 1401.

[0050] like Figure 1 and Figure 2 In the figure, a feeding bucket 2 is installed on the discharging assembly 1, and the feeding bucket 2 is located directly above the rotation trajectory of the inner cylinder 16, and is located on the side of the guide plate 112 opposite to the guide groove 113. A driving motor 7 for driving the transmission shaft 12 is installed under the protective tank 11 through a fixing part. The transmission shaft 12 is driven by the driving motor 7, and when the inner cylinder 16 rotates to the bottom of the feeding bucket 2, the material in the feeding bucket 2 will leak into the inner cylinder 16 and the outer cylinder 17.

[0051] like Figure 2 and Figure 3 In the embodiment, a collecting hopper 114 is provided in the protective tank 11, and the collecting hopper 114 is installed at the top of the connecting pipe 3. The collecting hopper 114 is located on the side of the guide plate 112 where the guide groove 113 is provided, and is located directly below the rotation track of the outer cylinder 17. When the outer cylinder 17 rotates to the side of the guide plate 112 where the guide groove 113 is provided, the closing cover 18 at the bottom thereof will flip open to discharge the material therein into the collecting hopper 114 for collection.

[0052] like Figure 6 In the figure, two servo motors 46 are installed on the side wall of the dividing block 41 through fixing parts, and the two rotating shafts 44 are respectively fixed on the output shafts of the two servo motors 46, and a PLC control module 47 for controlling the two servo motors 46 is installed on the side of the dividing block 41.

[0053] like Figure 6 and Figure 7In the figure, the heating component 9 includes a protective shell 91, which is installed under the dividing block 41, and a storage barrel 92 corresponding to the bottom opening of multiple No. 2 material guide cavities 43 is installed in the protective shell 91. A heating wire 93 is arranged on the outer wall of the storage barrel 92, and a heating control module 96 for controlling the heating wire 93 is installed on the outer wall of the protective shell 91, and the heating control module 96 is connected to the PLC control module 47 through a control line. A plurality of discharge pipes 94 are fixedly connected under the protective shell 91 corresponding to the plurality of storage barrels 92, and a closing valve 95 is installed on the plurality of discharge pipes 94. The die-casting component 5 is installed at the ends of the plurality of discharge pipes 94. When the die-casting component 5 is in operation, the material slurry in the storage barrel 92 can be extracted through the discharge pipe 94, and under the action of the closing valve 95, the material slurry in the storage barrel 92 can only flow in a single direction toward the die-casting component 5.

[0054] like Fig.10 In the figure, the die-casting component 5 includes a die-casting tank 51, which is installed at the ends of multiple discharge pipes 94. A fixing frame 52 is fixedly connected to the upper opening of the die-casting tank 51, and a hydraulic rod 53 is installed on the fixing frame 52. A piston plate 54 is fixedly connected to the bottom end of the hydraulic rod 53, and the piston plate 54 is slidably arranged in the die-casting tank 51. The die-casting tube 6 is installed on the side of the die-casting tank 51 opposite to the discharge pipe 94. When the piston plate 54 moves in the die-casting tank 51, the material slurry in the heating component 9 can be extracted through the discharge pipe 94, and the material slurry in the die-casting tank 51 can be squeezed through the die-casting tube 6 and injected into the die-casting mold.

[0055] like Figure 1 In the figure, a No. 1 bracket 8 for support is installed on the outer side of the discharging component 1, and a No. 2 bracket 10 for support is installed on the outer side of the heating component 9. The No. 1 bracket 8 is used to support the discharging component 1, and the No. 2 bracket 10 is used to support the heating component 9, so as to improve the supporting stability of the device and ensure the normal use of the device.

[0056] During operation, since the existing automatic feeding die-casting device cannot control the discharge amount of solid materials, if too much solid material is discharged, the material melting time will be prolonged, which will lead to a long production time, and too much slurry injection will cause an extra part of the molded parts to require secondary processing and removal, while too little material discharged will cause the molded parts to be missing corners, and when in use, after the solid material is put into the receiving hopper and the receiving tube, it is necessary to wait for it to melt before the die-casting process can be carried out, and multiple batches of materials cannot be melted at the same time, resulting in slow production speed and serious impact on production efficiency. In this scheme, by putting the solid material into the feeding bucket 2, and then controlling the drive motor 7 to run When the driving motor 7 is running, it will drive the transmission shaft 12 to rotate in the protective tank 11. When the transmission shaft 12 rotates, it will drive the upper rotating disk 13 to rotate in contact with the top of the protective tank 11. When the transmission shaft 12 rotates, it will drive the sliding sleeve 14 to rotate synchronously with the transmission shaft 12 through the engagement of the limiting rib groove 1401 and the limiting rib 1402. When the sliding sleeve 14 rotates, it will drive the lower rotating disk 15 to rotate, and then drive the lower rotating disk 15 and the upper rotating disk 13 to rotate synchronously with the transmission shaft 12 as the center. When the upper rotating disk 13 and the lower rotating disk 15 rotate, they will drive the inner cylinder 16 and the outer cylinder 17 to rotate around the transmission shaft 12;

[0057] Under the blocking limit of the bottom surface of the guide plate 112 on the connecting rod 1801, the closing cover 18 will be blocked at the bottom opening of the outer cylinder 17. When one set of the inner cylinder 16 and the outer cylinder 17 moves to the bottom of the feeding bucket 2, the material in the feeding bucket 2 will leak into the inner cylinder 16 and the outer cylinder 17, and under the blocking of the closing cover 18, the material will remain in the inner cylinder 16 and the outer cylinder 17. With the driving of the transmission shaft 12, the inner cylinder 16 and the outer cylinder 17 loaded with the material will rotate around the transmission shaft 12 and move the side of the guide plate 112 provided with the guide groove 113, and the connecting rod 1801 will slide on the bottom surface of the guide plate 112 during the movement. When the connecting rod 1801 moves to the guide groove 113 and is located above the collecting hopper 114, the inner cylinder 16 and the outer cylinder 17 will slide on the bottom surface of the guide plate 112. Under the action of the weight of the material in the cylinder 17 and the deadweight of the closing cover 18, the closing cover 18 will flip open from the bottom of the outer cylinder 17, and at this time, the materials in the inner cylinder 16 and the outer cylinder 17 will leak into the collecting hopper 114, and the other set of inner cylinders 16 and outer cylinders 17 will move to the bottom of the feeding bucket 2 to load materials under the state that the closing cover 18 blocks the bottom opening of the outer cylinder 17, and with the drive of the transmission shaft 12, the inner cylinder 16 and the outer cylinder 17 that have released the materials will continue to rotate around the transmission shaft 12, and under the guidance of the guide groove 113, the closing cover 18 will re-seal the bottom opening of the outer cylinder 17 and move to the bottom of the feeding bucket 2, and the other set of inner cylinders 16 and outer cylinders 17 loaded with materials will transport the materials to the top of the collecting hopper 114 and release them, so as to achieve the effect of continuous material discharge;

[0058] The material put into the collecting hopper 114 will enter the material distribution block 41 through the connecting pipe 3. After entering the material distribution block 41, the material will enter the No. 1 material guide cavity 42, and under the guidance of the two material guide plates 45, it will enter one of the No. 2 material guide cavities 43, and one of them will enter the corresponding storage barrel 92 under the guidance of the No. 2 material guide cavity 43, and cooperate with the heating control module 96 to control the heating wire 93 to heat. When the heating wire 93 is heated, it will melt the material in the storage barrel 92, and the corresponding closing valve 95 below it is in a closed state;

[0059] After the material is melted, the hydraulic rod 53 is controlled to contract and the corresponding closed valve 95 is opened. When the hydraulic rod 53 contracts, it drives the piston plate 54 to move upward in the die-casting tank 51, so as to draw the melted material slurry in the storage cylinder 92 into the die-casting tank 51 through the corresponding discharge pipe 94. Then, the hydraulic rod 53 is controlled to extend. When the hydraulic rod 53 extends, the material slurry in the die-casting tank 51 is injected into the die-casting mold through the die-casting pipe 6, and the closed valve 95 is in a closed state to prevent the material slurry in the die-casting tank 51 from flowing back, thereby achieving the function of feeding;

[0060] Through the continuous discharge of the discharge component 1, each discharged material will enter the material distribution block 41. At this time, two servo motors 46 are used to drive the two rotating shafts 44, so that the two rotating shafts 44 drive the guide plate 45 to rotate at the connecting opening between the No. 1 guide cavity 42 and the multiple No. 2 guide cavities 43, so that each batch of materials entering the No. 1 guide cavity 42 is guided into different No. 2 guide cavities 43. Under the guidance of the multiple No. 2 guide cavities 43, each batch of materials will enter different storage barrels 92. Multiple storage barrels 92 and the heating wires 93 thereon are used to heat multiple batches of materials at the same time. During processing, one of the closed valves 95 is controlled to be opened to pass through the die-casting component 5. The material slurry in one of the storage barrels 92 is extracted. After the slurry is discharged, the closed valve 95 is controlled to be closed again. As the material discharging component 1 continues to feed, the two material guide plates 45 are controlled to change their angles to feed the subsequent materials into the storage barrel 92 after the slurry is extracted for melting. When the die-casting component 5 is operated again after the die-casting process, the closed valve 95 under the remaining storage barrel 92 where the material has been melted is controlled to be opened to discharge the material slurry in the other storage barrels 92 and feed the material into the empty storage barrel 92 to achieve the effect of continuous melting, which can effectively reduce the time for waiting for the material to melt, ensure that the die-casting component 5 can continuously perform the die-casting process, and thus improve the production efficiency.

[0061] When it is necessary to adjust the discharge amount of the material each time, the electric telescopic rod 111 is controlled to be extended and retracted. When the electric telescopic rod 111 is extended and retracted, it will drive the support sleeve 19 to move up and down through the fixed ring 110. Under the interlocking limit of the annular groove 1901 and the limit ring 1902, when the support sleeve 19 moves up and down, it will drive the sliding sleeve 14 to move up and down on the outside of the transmission shaft 12, and then drive the lower rotating disk 15 to move up and down in the protective tank 11 to adjust the distance between the lower rotating disk 15 and the upper rotating disk 13. When the lower rotating disk 15 moves, it will drive the outer cylinder 17 to slide on the outside of the inner cylinder 16 to adjust the capacity of the inner cylinder 16 and the outer cylinder 17, and then adjust the amount of material discharged from the inner cylinder 16 and the outer cylinder 17 into the collecting hopper 114;

[0062] The cooperation achieves the effect of adjusting the discharge amount, effectively avoiding the molding qualification rate of processed parts, and can melt multiple batches of materials at the same time, reducing the waiting time for melting to increase the die-casting processing speed, and effectively improving production efficiency.
