Description

Technical Field

[0001] This invention belongs to the field of casting machine technology, specifically a casting machine outer mold that buffers the mold opening force. Background Technology

[0002] With the widespread use of high-efficiency molding equipment, production cycles are accelerating, putting immense pressure on manual operations. Problems in the pouring process often constrain the molding line's capacity, resulting in high scrap rates, significant molten iron waste, and frequent burns among pouring workers. To change this situation, mechanized and automated pouring machines must be adopted.

[0003] The existing mold opening principle of casting machines is usually to apply forces in opposite directions to both sides of the mold to pull it open. Therefore, the applied mold opening force is usually large. After the mold is opened, the resistance opposite to the pulling force of the device will disappear instantly, but the pulling force cannot disappear instantly. The large inertial pulling force will damage the internal structure of the device and reduce the service life of the device. Therefore, it is necessary to deal with this inertial pulling force. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a casting machine outer mold that buffers the mold opening force. This solves the problem that after the mold opens, the resistance opposite to the device's tension disappears instantly, while the tension cannot disappear instantly. The large inertial tension will damage the internal structure of the device and reduce its service life.

[0005] The technical solution adopted by the present invention to solve its technical problem is as follows: the casting machine outer mold of the present invention with buffered mold opening force includes a mold box, a closed baffle is snapped on the upper surface of the mold box, and a pressure device is provided at the axial center of the lower surface of the mold box.

[0006] Preferably, the casting mold box includes a modified shell. A buffer spring is fixedly connected to the axis at the lower part of the inner wall of the modified shell. A movable tray is fixedly connected to the top of the buffer spring. Sliding side shells are symmetrically arranged on the left and right sides of the axis of the modified shell. A fixed insert is slidably connected to the upper part of the inner wall of the sliding side shell. Pull arms are symmetrically arranged on the left and right sides of the outer surface of the movable tray. Ventilation devices are symmetrically arranged on the left and right sides of the upper part of the inner wall of the modified shell. A cooling chamber is opened at the lower part of the inner wall of the modified shell. Water supply devices are symmetrically arranged on the left and right sides of the cooling chamber. Before using the device for casting, the upper closed baffle is opened. Then, the mold is fixedly installed on the upper surface of the movable tray. After the molten raw material is injected into the mold, the closed baffle is pressed down to close it. The bottom end of the closed baffle is inserted into the inner wall of the modified shell. The side of the sliding side shell is locked with the upper corner of the mold. Then, water is injected into the cooling chamber through the water supply device until the cooling chamber is full of water. The mold placed on the upper surface of the movable tray is cooled down.

[0007] Preferably, the pressurizing device includes a fixed rotating machine, a turbine rod is fixedly connected to the outer surface of the output shaft of the fixed rotating machine, a connecting sleeve is rotatably connected to the outer surface of the turbine rod, fixed guide tubes are evenly arranged on the inner wall of the connecting sleeve, and a vertical pipe assembly is fixedly connected to the top end of the fixed guide tube. After a period of time, the model cools and solidifies, and the turbine rod is controlled to rotate clockwise by the fixed rotating machine. During the rotation of the turbine rod, the air below is introduced into the interior of the connecting sleeve and into the interior of the vertical pipe assembly through the fixed guide tube.

[0008] Preferably, the vertical tube assembly includes a fixed tube shell, with a limiting slide tube movably connected to the upper part of the inner wall of the fixed tube shell. A small spring is sleeved on the lower part of the outer surface of the limiting slide tube, and a side baffle is slidably connected to the middle part of the outer surface of the limiting slide tube. As the gas introduced into the fixed conduit gradually increases, the top of the limiting slide tube is sealed by the lower surface of the sealing baffle, and the pressure inside the fixed tube shell gradually increases. The pressure pushes the sealing baffle upward, and the limiting slide tube slides upward. During the upward movement of the sealing baffle, the lower surface of the sealing baffle pushes the sliding side shell upward through the tension arm, thereby pulling the mold upward. The buffer spring is gradually stretched, and the tension of the buffer spring gradually increases until the pressure inside the fixed tube shell is sufficiently high. Due to excessive tension, the mold above the movable tray is separated from the mold under the pull of the upper and lower sides. During this process, the buffer spring is stretched to a certain extent, and then the movable tray above is pulled down, and the mold is completely separated. Then the closing baffle is pulled to take out the mold after it is opened, and the finished mold part is obtained. During the mold opening process, the tension applied to the mold gradually increases. When the mold is opened, the bottom end of the limiting slide tube will also stop extending due to the blocking effect of the side baffle, so that the overall extension range of the vertical tube group is a certain value, preventing the internal pressure of the vertical tube group from being too high and causing the closing baffle to rise rapidly at the moment of mold opening, which would cause the mold opening force to be too large. This ensures the safety of the mold opening operation and reduces the damage to the device.

[0009] Preferably, the number of vertical pipe assemblies is four, and the number of fixed conduits is four. The top end of the fixed conduit extends into the interior of the cooling chamber through a through-hole. The upper part of the outer surface of the fixed conduit is slidably connected to the lower part of the inner wall of the fixed pipe shell. The bottom end of the fixed pipe shell is fixedly connected to the lower part of the inner wall of the modified box shell. The upper part of the outer surface of the connecting sleeve is fixedly connected to the lower surface of the modified box shell. The outer surface of the side baffle is fixedly connected to the upper part of the inner wall of the fixed pipe shell. The top end of the limiting slide tube extends to the outside of the fixed pipe shell. The top end of the limiting slide tube is fixedly connected to the lower surface of the closing baffle. This device uses small springs and buffer springs to provide multi-stage buffering inside the device during the mold opening process. On the one hand, it can ensure the smooth progress of the mold opening work. On the other hand, it can buffer the impact force received by the device after mold opening. In addition, the device has a maximum mold opening limit and can control the mold opening force within a certain safe range, making it safer and more reliable.

[0010] Preferably, there are two sliding side shells, with the left and right sides of the outer surface of the sliding side shells slidably connected to the upper part of the inner wall of the modified box shell. There are also two fixing strips, with the upper part of the fixing strips fixedly connected to the upper part of the inner wall of the modified box shell. The top of the tension arm is fixedly connected to the lower part of the outer surface of the closed baffle, and the bottom of the tension arm is slidably connected to the side of the movable tray. The side of the movable tray is slidably connected to the upper part of the inner wall of the modified box shell. A mold is fixedly connected to the upper surface of the movable tray. Because the mold opening process of this device is relatively smooth, and the related devices will not move excessively after the mold is opened, the mold is completely inside the modified box shell during the molding and mold opening process. The mold may crack due to the thermal expansion and contraction of the internal material. The modified box shell can provide protection, and the hot air released by the mold at the moment of mold opening can be absorbed and blocked by the interior of the modified box shell to prevent the operator from being burned by hot air.

[0011] Preferably, the ventilation device includes a fixed rotating rod, with a support plate rotatably connected to the lower part of the outer surface of the fixed rotating rod. Telescopic arms are provided on both the left and right sides of the outer surface of the fixed rotating rod. A vertical sliding plate is fixedly connected to the side of the outer surface of the fixed rotating rod away from the movable tray via the telescopic arms. Elastic balance belts are fixedly connected to the upper and lower sides of the outer surface of the vertical sliding plate. During mold opening, the tension arm pulls the telescopic arms on both sides upwards. The top of the telescopic arm controls the rotation of the telescopic arm on the other side via the fixed rotating rod, thereby sliding the vertical sliding plate downwards. At this time, the secondary ventilation port is opened. At the instant the mold opens, the air released from inside the mold... The pressurized gas first passes through the gap between the fixed insert and the inner wall of the modified housing, and finally is discharged to the outside through the secondary vents on both sides. Since the main vent and the secondary vent are staggered, the gas will pass through the gap between the secondary vent and the main vent, thus making a sound. At this time, the operator can hear the sound from the outside, and thus determine that the internal mold opening is complete. Because the mold opening process of this device is relatively smooth, and the mold is in a relatively sealed state throughout the mold opening process, the operator can determine whether the internal mold opening is complete by listening to the sound of air flow from the outside, so as to remove the mold in time and improve work efficiency.

[0012] Preferably, a secondary ventilation opening is provided on the side of the modified box shell cavity near the vertical slide plate, and a main ventilation opening is provided on the side of the modified box shell cavity away from the vertical slide plate.

[0013] Preferably, the side of the outer surface of the fixed rotating rod closest to the movable tray is fixedly connected to the lower part of the outer surface of the tension arm via a telescopic arm; the bottom end of the support plate is fixedly connected to the upper part of the inner wall of the modified box; the middle part of the outer surface of the fixed rotating rod is rotatably connected to the top end of the support plate; the side of the outer surface of the vertical sliding plate away from the telescopic arm is slidably connected to the inner wall of the modified box; and the top end of the telescopic arm is fixedly connected to the outer surface of the fixed rotating rod.

[0014] Preferably, the water supply device includes a side opening, the inner wall of which is fixedly connected to a heat-insulating sandwich panel. A water supply pipe is fixedly connected to the middle of the inner wall of the heat-insulating sandwich panel. An extension slide is slidably connected to the inner wall of the water supply pipe near the buffer spring. Openings are evenly distributed in the middle of the inner wall of the extension slide. Before mold opening, the user injects water into the cooling chamber through the water supply pipe to ensure the internal temperature of the device is low, allowing the components inside the mold to form quickly. During mold opening, the movable tray rises under tension, increasing the volume and decreasing the pressure inside the cooling chamber. The outside air then pushes the extension slide into the cooling chamber, causing it to slide into the interior through its opening. After the cooling chamber is pressurized, the buffer spring tends to pull the movable tray back to its original position after mold opening. However, the pressure in the lower cooling chamber is the same as the outside air pressure. At this time, the bottom end of the extension slide retracts into the water supply pipe. Because the device cannot be completely sealed, the air pressure inside the cooling chamber will slowly escape to the outside through the relevant gaps, the buffer spring will slowly return to its original position, and the movable tray will slowly slide down. During this time, the operator can remove the mold directly above the movable tray, and then the movable tray will slide deep into the device.

[0015] Preferably, the end of the water supply pipe near the buffer spring extends into the interior of the modified housing, the outer surface of the extension slide is slidably connected to the inner wall of the heat insulation sandwich panel, and the bottom end of the extension slide is slidably connected to the inner wall of the water supply pipe. This device sets the initial position of the movable tray in a deeper position, so that the mold is less disturbed during the cooling process, which is also beneficial to protect the operators outside. In addition, during the process of removing the mold, the movable tray will not quickly reset under the action of pressure, thus making it more convenient for the operator to remove the mold.

[0016] Preferably, the horizontal height of the secondary vent is lower than that of the main vent, and the main vent and the secondary vent are staggered.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. During the mold opening process, the tension applied to the mold gradually increases. After the mold is opened, the bottom end of the limiting slide tube will stop elongating due to the blocking effect of the side baffle. This keeps the overall elongation range of the vertical tube assembly at a certain value, preventing excessive internal pressure in the vertical tube assembly from causing the closing baffle to rise rapidly at the moment of mold opening, thus avoiding the risk of excessive mold opening force. This ensures the safety of the mold opening operation and reduces damage to the device.

[0019] 2. Because the mold opening process of this device is relatively smooth, and the related devices will not move excessively after the mold is opened, the mold is completely inside the modified box shell during the molding and mold opening process. The mold may crack due to the thermal expansion and contraction of the internal material. The modified box shell can provide protection, and the hot air released by the mold at the moment of mold opening can be absorbed and blocked by the interior of the modified box shell to prevent the operator from being burned by the hot air.

[0020] 3. Because the mold opening process of this device is relatively smooth, and the mold is in a relatively sealed state throughout the process, the operator can determine whether the mold opening is complete by listening to the sound of airflow from the outside, so as to remove the mold in time and improve work efficiency.

[0021] 4. This device uses small springs and buffer springs to provide multi-stage buffering inside the device during the mold opening process. On the one hand, it can ensure the smooth operation of the mold opening work, and on the other hand, it can buffer the impact force on the device after the mold opening. In addition, the device has a maximum mold opening limit, which can control the mold opening force within a certain safe range, making it safer and more reliable.

[0022] 5. The device sets the initial position of the movable tray in a deeper location, which reduces interference to the mold during the cooling process and helps protect operators. Furthermore, during the mold removal process, the movable tray will not quickly return to its original position under pressure, making it easier for operators to remove the mold.

[0031] Example 1

[0032] Please see Figures 1-4 The present invention provides a technical solution: an outer mold for a casting machine that buffers the mold opening force, including a mold box 1, characterized in that: a closed baffle 2 is snapped onto the upper surface of the mold box 1, and a pressure device 3 is provided at the axial center of the lower surface of the mold box 1.

[0033] The molding box 1 includes a modified box shell 11. A buffer spring 13 is fixedly connected to the axis at the lower part of the inner wall of the modified box shell 11. A movable tray 14 is fixedly connected to the top of the buffer spring 13. Sliding side shells 15 are symmetrically arranged on the left and right sides of the axis at the modified box shell 11.

Ventilation devices 5 are symmetrically arranged on the left and right sides of the upper part of the inner wall of the modified box shell 11. A cooling chamber 12 is opened in the lower part of the inner wall of the modified box shell 11. Water supply devices 6 are symmetrically arranged on the left and right sides of 2. Before using the device for casting, the upper closed baffle 2 is opened, and then the mold is fixedly installed on the upper surface of the movable tray 14. After the molten raw material is injected into the mold, the closed baffle 2 is pressed down to close it. The bottom end of the closed baffle 2 is inserted into the inner wall of the modified box shell 11, and the side of the sliding side shell 15 is locked with the upper corner of the mold. Then, water is injected into the cooling chamber 12 through the water supply device 6 until the cooling chamber 12 is full of water. The mold placed on the upper surface of the movable tray 14 is cooled down.

[0034] The pressurizing device 3 includes a fixed rotating machine 31. A turbine rod 32 is fixedly connected to the outer surface of the output shaft of the fixed rotating machine 31. A connecting sleeve 33 is rotatably connected to the outer surface of the turbine rod 32. Fixed guide tubes 34 are evenly arranged on the inner wall of the connecting sleeve 33. A vertical pipe assembly 4 is fixedly connected to the top end of the fixed guide tube 34.

[0035] The vertical tube assembly 4 includes a fixed tube shell 41, a limiting slide tube 43 is movably connected to the upper part of the inner wall of the fixed tube shell 41, a small spring 44 is sleeved on the lower part of the outer surface of the limiting slide tube 43, and a side baffle 42 is slidably connected to the middle part of the outer surface of the limiting slide tube 43.

[0036] There are four vertical pipe groups 4 and four fixed conduits 34. The top of the fixed conduit 34 extends into the interior of the cooling chamber 12 through the through-hole. The upper part of the outer surface of the fixed conduit 34 is slidably connected to the lower part of the inner wall of the fixed pipe shell 41. The bottom end of the fixed pipe shell 41 is fixedly connected to the lower part of the inner wall of the modified box shell 11. The upper part of the outer surface of the connecting sleeve 33 is fixedly connected to the lower surface of the modified box shell 11. The outer surface of the side baffle 42 is fixedly connected to the upper part of the inner wall of the fixed pipe shell 41. The top of the limiting slide tube 43 extends to the outside of the fixed pipe shell 41. The top of the limiting slide tube 43 is fixedly connected to the lower surface of the closing baffle 2.

[0037] There are two sliding side shells 15. The left and right sides of the outer surface of the sliding side shell 15 are slidably connected to the upper part of the inner wall of the modified box shell 11. There are two fixing strips 16. The upper part of the fixing strip 16 is fixedly connected to the upper part of the inner wall of the modified box shell 11. The top of the tension arm 17 is fixedly connected to the lower part of the outer surface of the closed baffle 2. The bottom of the tension arm 17 is slidably connected to the side of the movable tray 14. The side of the movable tray 14 is slidably connected to the upper part of the inner wall of the modified box shell 11. A mold is fixedly connected to the upper surface of the movable tray 14.

[0038] After a period of time, the model cools and solidifies. The turbine rod 32 is controlled to rotate clockwise by the fixed rotating machine 31. During the rotation, the turbine rod 32 introduces the air below into the interior of the connecting sleeve 32 and into the interior of the vertical pipe group 4 through the fixed conduit 34.

[0039] As the gas introduced into the fixed conduit 34 gradually increases, and the top of the limiting slide tube 43 is sealed by the lower surface of the sealing baffle 2, the pressure inside the fixed tube shell 41 gradually increases. The pressure pushes the sealing baffle 2 upward, and the limiting slide tube 43 slides upward. During the upward movement of the sealing baffle 2, the lower surface of the sealing baffle 2 pushes the sliding side shell 15 upward through the tension arm 17, thereby pulling the mold upward. The buffer spring 13 is gradually stretched, and the tension of the buffer spring 13 gradually increases until the pressure inside the fixed tube shell 41 is large enough. Due to the excessive tension, the mold above the movable tray is separated from the mold under the action of the tension on both sides. During this process, the buffer spring 13 is stretched to a certain extent, and then the movable tray 14 above is pulled downward, and the mold is completely separated. Then the sealing baffle 2 is pulled to remove the mold after it is opened, and the finished mold part is obtained.

[0040] Example 2

[0041] Please see Figure 1 , Figure 2 , Figure 5 The present invention provides a technical solution: based on embodiment one, a casting machine outer mold for buffering mold opening force, including a mold box 1, characterized in that: a closed baffle 2 is snapped onto the upper surface of the mold box 1, and a pressure device 3 is provided at the axial center of the lower surface of the mold box 1.

[0042] The molding box 1 includes a modified box shell 11. A buffer spring 13 is fixedly connected to the axis at the lower part of the inner wall of the modified box shell 11. A movable tray 14 is fixedly connected to the top of the buffer spring 13. Sliding side shells 15 are symmetrically arranged on the left and right sides of the axis of the modified box shell 11. A fixed insert 16 is slidably connected to the upper part of the inner wall of the sliding side shell 15. Pull arms 17 are symmetrically arranged on the left and right sides of the outer surface of the movable tray 14. Ventilation devices 5 are symmetrically arranged on the left and right sides of the upper part of the inner wall of the modified box shell 11. A cooling chamber 12 is opened in the lower part of the inner wall of the modified box shell 11. Water supply devices 6 are symmetrically arranged on the left and right sides of the cooling chamber 12.

[0043] There are two sliding side shells 15. The left and right sides of the outer surface of the sliding side shell 15 are slidably connected to the upper part of the inner wall of the modified box shell 11. There are two fixing strips 16. The upper part of the fixing strip 16 is fixedly connected to the upper part of the inner wall of the modified box shell 11. The top of the tension arm 17 is fixedly connected to the lower part of the outer surface of the closed baffle 2. The bottom of the tension arm 17 is slidably connected to the side of the movable tray 14. The side of the movable tray 14 is slidably connected to the upper part of the inner wall of the modified box shell 11. A mold is fixedly connected to the upper surface of the movable tray 14.

[0044] The ventilation device 5 includes a fixed rotating rod 51, a support plate 52 is rotatably connected to the lower part of the outer surface of the fixed rotating rod 51, telescopic arms 53 are provided on both the left and right sides of the outer surface of the fixed rotating rod 51, and a vertical slide plate 54 is fixedly connected to the side of the outer surface of the fixed rotating rod 51 away from the movable tray 14 through the telescopic arm 53. Elastic balance belts 55 are fixedly connected to the upper and lower sides of the outer surface of the vertical slide plate 54.

[0045] A secondary ventilation opening 57 is provided on the side of the modified housing 11 closest to the vertical slide plate 54, and a main ventilation opening 56 is provided on the side of the modified housing 11 away from the vertical slide plate 54.

[0046] The side of the outer surface of the fixed rotating rod 51 closest to the movable tray 14 is fixedly connected to the lower part of the outer surface of the tension arm 17 via the telescopic arm 53.

[0047] The horizontal height of the secondary vent 57 is lower than that of the main vent 56, and the main vent 56 and the secondary vent 57 are staggered.

[0048] During the mold opening process, the tension arm 17 pulls the telescopic arms 53 on both sides upward. The top of the telescopic arm 53 controls the rotation of the telescopic arm 53 on the other side through the fixed rotating rod 51, thereby sliding the vertical slide plate 54 downward. At this time, the secondary ventilation port 57 is opened. When the mold opens, the pressurized gas released inside the mold first passes through the gap between the fixed insert 16 and the inner wall of the modified box shell 11, and finally is discharged to the outside from the secondary ventilation ports 57 on both sides. Since the main ventilation port 56 and the secondary ventilation port 57 are intertwined, the gas will pass through the gap between the secondary ventilation port 57 and the main ventilation port 56, thus making a sound. At this time, the operator can hear the sound from the outside, thus determining that the internal mold opening is complete.

[0049] Because the mold opening process of this device is relatively smooth, and the mold is in a relatively sealed state throughout the process, the operator can determine whether the mold opening is complete by listening to the sound of airflow from the outside, so as to remove the mold in time and improve work efficiency.

[0058] Before mold opening, the user injects water into the cooling chamber 12 through the water supply pipe 61 to ensure that the internal temperature of the device is low, allowing the components inside the mold to be formed quickly. During the mold opening process, the movable tray 14 will rise under the action of tension, so the volume inside the cooling chamber 12 increases and the pressure decreases. Therefore, the outside air will push the extension slide 62 into the interior of the cooling chamber 12, and then the opening 63 of the extension slide 62 will slide into the interior of the cooling chamber 12. After the internal pressure of the cooling chamber 12 is increased, when the mold opening is completed, the buffer spring 13 tends to pull the movable tray 14 back to its original position. However, the pressure of the lower cooling chamber 12 is the same as the external air pressure. At this time, the bottom end of the extension slide 62 retracts into the interior of the water supply pipe 61. Because the device cannot actually be completely sealed, the air pressure inside the cooling chamber 12 will slowly be released to the outside through the relevant gaps, the buffer spring 13 will slowly return to its original position, and the movable tray 14 will slowly slide down. During this time, the operator can remove the mold directly above the movable tray 14, and then the movable tray 14 will slide into the depth of the device.
