Embodiment
[0035] Please refer to Figure 1-6 , the present invention provides a technical solution: a feeding component for a molding machine, including a box body 1, a molding machine body 2 is arranged on one side of the box body 1, a recycling bin 4 is connected to one side of the box body 1, the recycling bin 4 is used to recycle the screened impurities, and a box door for treating garbage is installed on one side of the bottom of the recycling bin 4;
[0036] A moving component is arranged on one side of the bottom of the box body 1; a cross plate 7 is fixed on the side of the box body 1 away from the recycling bin 4; a selection component 5 is arranged inside the box body 1, and a blocking component 3 is arranged on one side of the selection component 5;
[0037] To avoid waste of casting sand, a blocking component 3 is provided. The blocking component 3 includes a limit frame 33, a discharge frame 36 and a motor 38. A connecting rod 32 is inserted into one side of the limit frame 33. A second baffle 312 is fixed to the bottom of the connecting rod 32, and a second rack 313 is fixed to the top of the connecting rod 32. A first baffle 35 is seamlessly inserted into one side of the discharge frame 36. A first rack 37 is fixed to one side of the first baffle 35. A gear 39 is fixed to the output shaft end of the motor 38 and is meshed with the first rack 37 and the second rack 313 respectively. The width of the gear 39 is greater than the widths of the first rack 37 and the second rack 313, and the first rack 37 and the second rack 313 are located outside the gear 39, so that the first rack 37 and the second rack 313 will not collide with each other. A receiving frame 311 is fixed to the middle of the inner wall of the box body 1, and a discharge pipe 31 located outside the box body 1 is fixed to the bottom of the receiving frame 311. When the first baffle 35 moves to the right, a small gap is formed between the first baffle 35 and the discharge frame 36, and the casting sand will enter the top of the screen 52 in a small flow rate.
[0038] The outside of the second baffle 312 is inserted into the inside of the discharge pipe 31. The bottom of the motor 38 is fixed to one side of the top of the cross plate 7. A feeding box 6 is fixed to the top of the box body 1. The top of the discharge frame 36 is communicated with the discharge end of the feeding box 6. One side of the limit frame 33 is fixed to one side of the box body 1. When the gear 39 rotates counterclockwise, the first baffle 35 and the second baffle 312 are respectively inserted into the inside of the discharge pipe 31 and the discharge frame 36. When the gear 39 rotates clockwise, the first baffle 35 and the second baffle 312 respectively leave the inside of the discharge pipe 31 and the discharge frame 36. The first baffle 35 blocks one side of the discharge frame 36, and the second baffle 312 blocks one side of the discharge pipe 31, avoiding waste of the casting sand inside the discharge pipe 31. When it is necessary to load the casting sand onto the next processing table, at this time, the output shaft of the motor 38 rotates clockwise, so that the casting sand inside the discharge pipe 31 preferentially enters the inside of the processing table of the molding machine body 2. When the casting sand inside the feeding box 6, the receiving frame 311 and the discharge pipe 31 is used up, the casting sand is added into the box body 1 again through the screw conveyor.
[0039] A slide rail 34 is fixed to one side of the box body 1 and is slidably connected to the outside of the first baffle 35. The slide rail 34 makes the sliding of the first baffle 35 more stable. The outside of the second rack 313 penetrates through one side of the cross plate 7.
[0040] The moving component includes a hydraulic cylinder 8. The push rod end of the hydraulic cylinder 8 is fixed with a slide plate 9 installed at the bottom of the box body 1. A sliding frame 10 is fixed to one side of the molding machine body 2 and is slidably connected to the outside of the slide plate 9. Control the push rod end of the hydraulic cylinder 8 to retract, so that the slide plate 9 drives the box body 1 to move to the left, so that the feeding box 6 is located at the discharge end of the screw conveyor, avoiding the box body 1 for feeding from interfering with the work of the molding machine body 2.
[0041] The selection component 5 includes two fixed blocks 56. A spring 55 is connected to the top of the fixed block 56, and a fixed frame 54 is connected to the top of the spring 55. A screen 52 is installed inside the fixed frame 54, and a vibration motor 53 is installed on one side of the bottom of the fixed frame 54. A discharge hole 11 is opened on one side of the box body 1. When the first baffle 35 leaves the inside of the discharge rack 36, the casting sand enters the top of the screen 52. After the casting sand is screened by the screen 52, the impurities in the casting sand pass through the inclined screen 52 and enter the inside of the material guiding frame 51 through the discharge hole 11. The material guiding frame 51 is fixed to the outside of the box body 1 on one side of the discharge hole 11. The bottom of the hydraulic cylinder 8 is fixed to one side of the top of the sliding frame 10, and one side of the fixed block 56 is fixed to the inner side wall of the box body 1. The screen 52 is inclined, and the impurities are uniformly collected inside the recycling box 4. When the screen 52 is screening, the vibration motor 53 makes the spring 55 generate reciprocating elastic motion to prevent the casting sand from accumulating on the top of the screen 52.
[0042] Working principle: When the molding machine body 2 is in use, a screw conveyor is arranged on one side of the box body 1. The casting sand is added to the feeding end of the screw conveyor, and then the screw conveyor conveys the casting sand into the feeding box 6. Subsequently, the push rod end of the hydraulic cylinder 8 is controlled to push the sliding plate 9 and the box body 1 on its top to move towards the molding machine body 2, so that the discharge pipe 31 is located on the top of the processing table of the molding machine body 2;
[0043] At this time, the output shaft of the control motor 38 rotates clockwise, so that the output shaft of the motor 38 drives the gear 39 to rotate clockwise. The gear 39 is respectively meshed with the first rack 37 and the second rack 313, so that the first rack 37 drives the first baffle 35 to move to the right, and the second rack 313 drives the connecting rod 32 to slide upward inside the limiting frame 33. At the same time, the connecting rod 32 drives the second baffle 312 to move upward, so that the second baffle 312 leaves the inside of the discharge pipe 31;
[0044] The vibration motor 53 starts to work. Since the first baffle 35 leaves the inside of the discharge rack 36, the casting sand enters the top of the screen 52. After the casting sand is screened by the screen 52, the impurities in the casting sand pass through the inclined screen 52 and enter the inside of the material guiding frame 51 through the discharge hole 11, and the impurities are uniformly collected inside the recycling box 4. When the screen 52 is screening, the vibration motor 53 makes the spring 55 generate reciprocating elastic motion to prevent the casting sand from accumulating on the top of the screen 52;
[0045] At this time, under the action of the receiving rack 311 and the discharge pipe 31, the screened foundry sand is conveyed to the inner side of the processing table of the molding machine body 2. When the amount of the added foundry sand is sufficient, the output shaft of the motor 38 is controlled to rotate counterclockwise at this time, so that the first baffle 35 blocks one side of the discharge rack 36, and the second baffle 312 blocks one side of the discharge pipe 31, avoiding the waste of the foundry sand inside the discharge pipe 31. When it is necessary to feed the foundry sand onto the next sand mold, the output shaft of the motor 38 rotates clockwise at this time, so that the foundry sand inside the discharge pipe 31 preferentially enters the inner side of the processing table of the molding machine body 2. When the foundry sand inside the feeding box 6, the receiving rack 311 and the discharge pipe 31 is used up, the foundry sand is added into the box 1 again through the screw conveyor.
[0046] When it is necessary to add foundry sand into the feeding box 6, only need to control the push rod end of the hydraulic cylinder 8 to retract, so that the slide plate 9 drives the box 1 to move to the left, making the feeding box 6 located at the discharge end of the screw conveyor, avoiding the box 1 for feeding from interfering with the work of the molding machine body 2.
[0047] In summary, the vibration motor 53 drives the spring 55 to generate reciprocating elastic motion, preventing the accumulation of foundry sand on the top of the screen 52. The work of the vibration motor 53 causes the screen 52 to vibrate, which helps the uniform distribution and rapid passage of the foundry sand on the screen 52, thus improving the screening efficiency. The inclined setting of the screen 52 enables impurities to more easily enter the inner side of the guide frame 51 through the discharge holes 11, further promoting the separation and collection of impurities.
[0048] By controlling the opening and closing of the first baffle 35 and the second baffle 312 through the motor 38, the conveyance of the foundry sand from the discharge rack 36 and the discharge pipe 31 can be precisely controlled. When the amount of the foundry sand is sufficient, by closing the first baffle 35 and the second baffle 312, it can be ensured that the foundry sand will not continue to flow out, thus allowing the molding machine body 2 to perform the next processing operation, improving the efficiency of the entire casting process, reducing the waiting time. Preferentially using the foundry sand inside the discharge pipe 31 can ensure the full utilization of the foundry sand. When the foundry sand inside the discharge pipe 31 is used up, new foundry sand is added into the box 1 through the screw conveyor, which avoids the waste of the foundry sand and ensures the continuity of the casting process.
[0049] When it is necessary to add foundry sand into the feeding box 6, by controlling the push rod end of the hydraulic cylinder 8 to retract, the box 1 can be conveniently moved, aligning the feeding box 6 with the discharge end of the screw conveyor, and the foundry sand can be smoothly conveyed into the feeding box 6 without interrupting the work of the molding machine body 2, greatly improving the work efficiency and reducing the waiting time.
