[0035] Example

[0036] Reference Figures 1-11 The present invention discloses an integrated low-pressure casting equipment for automobile flooring, comprising a static template platform 1, which is installed on the ground by a bracket 68. A heat preservation furnace mechanism 10 is provided below the static template platform 1, and an opening and closing mechanism 4 connected by multiple support legs 3 is provided above the static template platform 1. Multiple core-pulling mechanisms 69 are respectively installed at the edge of the static template platform 1 between the static template platform 1 and the opening and closing mechanism 4. A part-removing robot arm 17 is also provided on the static template platform 1.

[0037] Furthermore, the opening and closing mechanism 4 includes a closing cylinder seat 11 horizontally mounted on the upper surface of multiple support legs 3. Two symmetrically arranged first drive cylinders 16 are provided on the closing cylinder seat 11. The piston rod of the first drive cylinder 16 is vertically upward and connected to a first top plate 14. A horizontally arranged transverse plate 70 is provided between the first top plate 14 and the closing cylinder seat 11. Four first guide sleeves 12 are provided between the transverse plate 70 and the closing cylinder seat 11, and the four first guide sleeves 12 are respectively located at the four corners of the closing cylinder seat 11. Three first guide rods 15 and one toothed guide rod 13 are connected to the first top plate 14. The first guide rods 15 and one toothed guide rod 13 are slidably engaged with the four first guide sleeves 12, and pass through the first guide sleeves 12. The closing cylinder seat 11 extends downward and is connected to a moving template 18. A casting ejection mechanism is provided on the moving template 18 for ejecting the casting.

[0038] Furthermore, the first drive cylinder 16 has a built-in displacement sensor 42 that can provide real-time position feedback. The drive cylinder is raised and lowered by an electro-hydraulic servo valve, and the position of the drive cylinder is closed-loop controlled by a servo controller. This ensures that the four corners of the moving template 18 rise and fall synchronously when the mold is opened, greatly improving the parallelism accuracy of the mold opening and closing.

[0039] To ensure the safety of the operating space below the moving template 18, a safety lock device driven by a cylinder is installed on the fitting cylinder seat 11. The safety lock device includes a first driving cylinder 19, a connecting block 20, a connecting rod 21, a spring, a guide platform 25, and a wedge block 23. The piston rod of the first driving cylinder 19 is positioned opposite to the toothed end of the toothed guide rod 13 and connected to the connecting block 20. One end of the connecting rod 21 is connected to the wedge block 23, and the other end is inserted into the connecting block 20. Furthermore, a sliding groove is provided on the side of the connecting block 20, and a positioning pin 24 through which the connecting rod 21 passes is provided. The positioning pin 24 can slide horizontally in the sliding groove. The spring is sleeved on the circumferential surface of the connecting rod 21. The wedge block 23 moves in the guide platform 25 and engages with the toothed surface of the toothed guide rod 13. Specifically, the toothed surface of the toothed guide rod 13 includes a right-angled surface on the upper side and an inclined surface on the lower side, and the inclined surface is inclined inward from top to bottom.

[0040] When the moving template 18 rises, the horizontal component of the toothed surface of the toothed guide rod 13 pushes the wedge block 23, causing the wedge block 23 to passively retract and move inward, thereby compressing the spring. When the moving template 18 is in place, the spring returns to its original position, causing the wedge block 23 to be locked below the right angle surface of the toothed guide rod 13.

[0041] When the moving template 18 descends, the first drive cylinder 19 actively retracts, causing the wedge block 23 to move backward, preventing it from continuing to be jammed with the toothed guide rod 13, thereby completing the unlocking of the moving template 18.

[0042] A casting ejection mechanism is provided on the moving template 18 for ejecting the casting. It includes a gantry frame 26, on which a second drive cylinder 29 and two symmetrically arranged gantry guide sleeves 27 are installed. The piston rod of the second drive cylinder 29 is vertically downward and connected to the ejection plate 30. Second guide rods 28 are slidably arranged in the gantry guide sleeves 27, and both second guide rods 28 are connected to the ejection plate 30. A push rod 31 is installed below the ejection plate 30. The number and position of the push rods 31 can be changed according to the actual situation.

[0043] In this embodiment, the second drive cylinder 29 is connected to the moving template 18 through the gantry frame 26, which can effectively prevent the influence of high temperature conduction of the mold on the drive cylinder.

[0044] The core-pulling mechanism 69 includes a support 32. Multiple vertically arranged T-slots are provided on the outside of the support 32. T-blocks 37 are slidably arranged in the T-slots. A cylinder seat 36 is connected to the outside of the multiple T-blocks 37. A third drive cylinder 34 is installed on the cylinder seat 36 and two symmetrically arranged second guide sleeves 35 are provided. A third guide rod 33 is slidably arranged in the second guide sleeves 35. One end of the third guide rod 33 passes through the cylinder seat 36 and the support 32 and is connected to the side template 38. The piston rod of the third drive cylinder 34 is also connected to the side template 38 at the same time.

[0045] Adjusting blocks 71 are installed on both sides of the side template 38. Vertical screws 72 are slidably connected to the adjusting blocks 71. Adjusting nuts 73 that are threadedly connected to the screws 72 are provided on the upper and lower sides of the adjusting blocks 71. This arrangement enables the side template 38 to have an adjustable center height, making it suitable for different molds.

[0046] The manipulator 17 of this utility model is installed on one side of the equipment body, including a base 39 installed on a static template platform 1. Two vertically arranged guide columns 47 are installed on the base 39. A second top plate 50 is provided on the upper surface of the guide columns 47. The guide columns 47 and the second top plate 50 are connected to form a frame. A lifting cylinder 46 is provided on the second top plate 50. The piston rod of the lifting cylinder 46 is vertically downward and connected to a rotating seat 51. The lower part of the rotating seat 51 is connected to a lifting guide sleeve 48 and a rotating guide sleeve 44, which are respectively slidably connected to the guide columns 47, through a connecting sleeve 74. The lifting cylinder 46 is connected to the rotating seat 51. The lifting guide sleeve 48 and the rotating guide sleeve 44 are driven to move up and down. The lifting guide sleeve 48 is located outside the rotating guide sleeve 44. A rotating cylinder 49 is horizontally arranged on the lifting guide sleeve 48 and connected to the rotating guide sleeve 44, so that the rotating guide sleeve 44 can rotate along the guide post 47. A telescopic arm 40 is horizontally installed on the rotating guide sleeve 44. The telescopic arm 40 is divided into two sections and is driven to extend and retract by a telescopic cylinder 45 (this is prior art and will not be described in detail here). A receiving plate 41 is arranged above the second section of the telescopic arm 40, and a buffer spring 43 is arranged at the bottom of the receiving plate 41.

[0047] After the mold is opened, the casting remains on the moving template 18. As the moving template 18 rises to the top position, the part-removing robot 17 rises and screws in, extending out of the receiving tray 41. The casting ejection mechanism ejects the casting, which falls into the receiving tray 41 and is then screwed out again. The movement trajectory of the receiving tray 41 is sufficient to remove the casting from the equipment. The buffer spring 43 provides a buffering effect. A sensor 42 is installed on the other side of the bottom of the receiving tray 41 to determine whether the casting has fallen.

[0048] In this embodiment, the heat preservation furnace mechanism 10 includes a heat preservation furnace 52, multiple sets of liquid riser pipe devices 56, and an exhaust device 55. The heat preservation furnace 52 is a large pool furnace with internal spiral pipes and is filled with insulation material around its perimeter. The insulation material includes, but is not limited to, aluminum silicate fiber and ceramic fiber. The insulation material is used to recover the heat energy of the high-temperature exhaust gas and preheat the intake air at the same time.

[0049] Furthermore, the riser tube device 56 includes a riser tube furnace cover 63 installed on the holding furnace 52, a riser tube seat 64 installed on the riser tube furnace cover 63, a riser tube 66 placed on the riser tube seat 64, and a replaceable plug 65 installed on the riser tube seat 64 for sealing the tube opening. Furthermore, the riser tube furnace cover 63 is filled with insulation material inside, and the insulation material has an eight-shaped structure, which can effectively concentrate the furnace gas heat to insulate and heat the riser tube 66, and the insulation material includes, but is not limited to: aluminum silicate fiber, ceramic fiber, etc.

[0050] A negative pressure extraction device 2 is provided on the static template platform 1. The negative pressure extraction device 2 can be a vacuum pump, which is connected to the mold cavity to realize negative pressure exhaust.

[0051] A temperature probe 67 is inserted at the position of the riser tube 66 in the riser tube furnace cover 63 to monitor the temperature of each riser tube 66 in real time. The gate layout of the multiple riser tubes 66 can also be adjusted by blocking unnecessary tubes and changing the number and layout of gates according to process requirements.

[0052] Furthermore, the exhaust device 55 includes a base plate 62 installed on one side of the heat preservation furnace 52. A second drive cylinder 58 is installed on the base plate 62, and its piston rod is connected to a sealing plate 60. Four small guide pillars 59 are provided on the sealing plate 60, and the top of the four small guide pillars 59 is connected to a valve block 61 to form a frame with the base plate 62. The valve block 61 is connected to the exhaust pipe of the heat preservation furnace 52. The second drive cylinder 58 drives the sealing plate 60 to rise and fall through the four guide pillars 47 and seal with the valve block 61.

[0053] The second drive cylinder 58 drives the high-temperature resistant sealing plate 60 to seal the large-diameter valve block 61, ensuring the sealing of high-temperature gas. The valve block 61 has a downward-facing exhaust port, allowing for safe and rapid exhaust of high-temperature gas. In this embodiment, a safety pressure reducing valve 54 is directly connected to the holding furnace 52. In the event of overpressure and loss of control within the furnace, the safety pressure reducing valve 54 can safely release pressure.

[0054] In this embodiment, a mold cooling mechanism is also provided, which includes a high-pressure cooling machine 8, a cooling control cabinet 7, a first inlet and return water distribution block 5, and a second inlet and return water distribution block 9. The first inlet and return water distribution block 5 and the second inlet and return water distribution block 9 are connected to the cooling control cabinet 7 through cooling water pipes 6. The cooling water flow rate of each channel can be controlled independently and compressed air can be blown. A mold temperature monitoring system is set up to monitor the temperature of each channel in real time and automatically adjust the flow rate of each channel to form a closed-loop control.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
