Description

Technical Field

[0001] This invention relates to the field of casting equipment technology, specifically to a casting demolding device. Background Technology

[0002] In the casting process, an upper and lower mold needs to be assembled, and molten metal is injected into the cavity formed by the mold. After the temperature of the molten metal decreases, it cools and forms the casting according to the cavity of the mold. During this process, in order to prevent the upper and lower molds from being unable to separate from the casting, a release agent needs to be sprayed on the inner wall of the mold cavity to assist in demolding the casting. Most of the existing demolding processes are manual, which requires lifting the upper mold to separate it from the lower mold. Alternatively, a mechanical structure can be used to fix the upper mold to a lifting device to achieve lifting demolding. However, when using the above structures, although they can lift the upper mold, if the lifting height is too small, it will still affect the removal of the casting from the lower mold, and it does not help with the demolding of the casting from the lower mold. Summary of the Invention

[0003] To address the problem that during the separation process of the upper and lower molds, only the upper mold and the casting are assisted in demolding, but the demolding of the lower mold and the casting is not significantly aided, this invention provides a casting demolding device.

[0004] The technical solution of this invention is as follows:

[0005] A casting demolding device for use with a mold that separates the upper and lower parts, comprising two bases arranged opposite each other;

[0006] Each of the bases is fixed with an opening and closing mechanism, which includes a ring rail, a movable seat, and a mounting base;

[0007] One end of the mounting base is fixedly connected to the base, and the other end is connected to a vertically arranged ring rail;

[0008] The circular rails on the two bases are arranged in parallel relative to each other;

[0009] Each of the upper and lower ends of the ring rail is slidably connected to a movable seat. Each movable seat has a connecting mechanism fixed on its inward side. The two pairs of movable seats on the two ring rails are arranged opposite to each other. The connecting mechanism is used to fix the mold.

[0010] The movable seats at both ends of the ring track are connected to a drive mechanism on the outward side. The drive mechanism can drive the two movable seats on the same side to move synchronously and in opposite directions along the upper and lower ends of the ring track.

[0011] Unlike existing lifting and mold-separating methods, this device separates the mold by rotation. After separation, the inner surfaces of the two molds can be easily coated with release agents and other substances. Furthermore, the device can be used with different molds.

[0012] The specific structure of the aforementioned drive mechanism is as follows: The drive mechanism includes:

[0013] A first layer plate and a second layer plate are sequentially arranged on the outside of the mounting base, with a gap between the first layer plate and the second layer plate;

[0014] The guide wall is arc-shaped and concentric with the ring rail, fixed inside the first or second layer plate, and two guide walls are symmetrically arranged relative to the horizontal plane passing through the center of the ring rail, with a guide hole between the two guide walls.

[0015] Four rotating wheels are provided, all of which are fixed inside the first or second layer plate and can rotate. The circumference of each rotating wheel is greater than 1 / 4 of the circumference of the ring rail.

[0016] Pull ropes are arranged in pairs on the outside of each guide wall and can move along the outer wall of the guide wall. One end of each pull rope is fixed to the movable seat through an external connector, and the other end passes through the guide hole and is fixed to an adjacent wheel. Each movable seat connects two pull ropes, and each pull rope is connected to a different wheel.

[0017] The outer side of the second layer plate is provided with driven gears corresponding to the number of rotating wheels. The driven gears are fixedly connected to the rotating wheels and are driven to rotate by the guide and drive components.

[0018] The guide arm guides the pull rope, allowing it to move along a preset route. Therefore, when in use, once the pull rope is fixed to the movable seat, the movable seat can be moved without any issue of the movable seat detaching from its position.

[0019] To ensure the mold can rotate to a horizontal position, two guide holes are symmetrically arranged, located on the same horizontal plane, with the horizontal plane passing through the center of the annular track. When pouring molten metal into the mold, it must remain horizontal, and the mold's position must be fixed by a structure to prevent misalignment of the movable seat.

[0020] The specific structure for driving the movable seat to rotate is as follows: the rotating wheels are symmetrically arranged in pairs about the horizontal plane containing the two guide holes, and the rotation centers of the two rotating wheels on the same side are on the same horizontal plane. The distance between the two rotating wheels on the same side is greater than the distance between two adjacent rotating wheels on separate sides. The rotation of the movable seats on the same ring rail must be synchronized. To ensure that the rotation of the movable seats can be synchronized, the same drive structure is needed to drive all actions. Therefore, the above arrangement is necessary.

[0021] To reduce the tension on the pull rope from the movable seat, the movable seat can rotate to abut against the mounting seat. After abutting against the mounting seat, the movable seat can appropriately reduce the tension on the pull rope, especially the lower movable seat, which, with the abutting support of the mounting seat, can complete the demolding of the casting.

[0022] The specific structure of the aforementioned connecting mechanism is as follows: the connecting mechanism includes a connecting upright plate fixed to the movable seat, a connecting horizontal plate connected to the connecting upright plate, and a movable extension member that can extend outward to one side of the mounting seat. The side of the movable extension member closest to the mounting seat is an inclined surface. To provide a protective function through the movable extension member, it is necessary to provide a structure that prevents the movable seat from slipping due to accidental exercise with the pull rope. The aforementioned movable extension member achieves this safety protection.

[0023] Building upon the aforementioned structure, the mounting base is further characterized by a vertical plane on the side closest to the connecting mechanism, with symmetrically arranged inclined planes on its upper and lower sides. The inclination angle of the inclined plane of the movable extension member is opposite to that of the inclined plane of the mounting base. The inclined planes provide support for the movable base, while the vertical plane allows the movable extension member to rely on the vertical plane, thus providing tilt protection.

[0024] Preferably, the movable seat is an arc-shaped seat with a central angle of 90°. The angle between the inclined surface of the mounting seat and the vertical plane is 45°-50°. The design of the arc-shaped seat must ensure fixation with the connecting mechanism. It is necessary to reserve a setting position for the mounting seat, but fixation needs to be achieved in multiple positions. If the inclined angle of the mounting seat is too large, the lower movable seat will not be able to complete the demolding action. If it is too small, it will cause problems with the fixation of the ring rail. The above design ensures that after the movable seat abuts against the mounting seat, there are no obstructions directly above the upper surface of the lower movable seat.

[0025] To guide the pull wire, both ends of the guide arm are equipped with rotatable rollers.

[0026] To accommodate molds of different lengths, the base is movably mounted on a horizontal rail, and the spacing is adjustable.

[0027] The beneficial effects of this invention are as follows: This invention is a casting demolding device, which differs from existing demolding mechanisms. This device simultaneously drives the upper mold and the lower mold, switching between a state of mutual contact and a state of mutual separation. In the state of mutual contact, the mold is in a horizontal state, and casting can be carried out normally. In the state of mutual separation, the upper mold and the lower mold are separated, and the lower mold is tilted. There are no obstructions in the vertical direction of the upper surface, so interference from the interfering structure can be avoided, and the casting can be demolded normally. Moreover, the demolding process is also very convenient after the tilting setting. Conventionally, the upper mold needs to be flipped when spraying the release agent, but with this device, the upper mold can be sprayed with the release agent directly in the state of mutual separation.

[0041] like Figure 1 , 2 The present invention discloses a casting demolding device, which includes a horizontally arranged cross rail 1 and two movable bases 2 on the cross rail 1. Therefore, the distance between the two bases 2 can be adjusted. Since the mold length and other specifications of castings are not uniform, this device can be used for demolding castings of various lengths and specifications when the distance between the two bases 2 can be adjusted.

[0042] Furthermore, each of the bases 2 is fixed with an opening and closing mechanism 3. The opening and closing mechanism 3 includes a mounting base 33 fixed to the base 2. The mounting base 33 is fixed with a vertically arranged ring rail 31. The two ring rails 31 are parallel to each other to ensure that the rotation planes are parallel to each other, avoiding the phenomenon that the mold 6 cannot be opened. Two movable seats 32 are provided on the ring rail 31. The movable seats 32 can move in a ring around the center of the ring rail 31. Since the mold 6 needs to be horizontal for casting during the use of this device, the mounting base 33 cannot be directly above or below the ring rail 31. Therefore, it can only be set on the front and rear sides. Generally, the front side is used to install and place the mold 6, and the rear side is used for connecting the mounting base 33 and the ring rail 31, i.e. Figure 3 , 4 The state shown.

[0043] In the design of the opening and closing mechanism 3 described above, in addition to the requirements for the fixed position of the ring rail 31, there are also requirements for the structural arrangement of the movable seat 32. First, the included angle between the planes containing the two end faces of the movable seat 32 is 90°, that is, as shown in the figure. Figure 3As shown, the movable seat 32 occupies 1 / 4 of the ring rail 31. The purpose of this setting is that, firstly, the movable seat 32 is subsequently used to guide the mold 6 and is fixed to the connecting mechanism 5 that fixes the mold 6. Therefore, the larger the structure of the movable seat 32, the more area can be used for fixing. The mold 6 includes two states: mutual separation and mutual contact. When it is mutual separation, the mold 6 must remain horizontal. When it is mutual separation, the upper mold and the lower mold of the mold 6 form a 90° angle to ensure that there are no obstructions in the vertical direction of the upper surface of the lower mold, so that the casting can be taken out normally. This requires the movable seat 32 to move in the direction of mutual separation and to maintain the state of mutual separation until the release agent is sprayed. Therefore, in order to reduce the pressure on the structure that drives the movable seat 32 to move and maintain its constant state, the movable seat 32 can be supported on the mounting base 33.

[0044] Therefore, the mounting base 33 is configured such that the side closest to the ring rail 31 is a vertical plane, and the upper and lower sides of the vertical plane are two inclined planes, with the extended surface of the inclined plane passing through the center of the ring rail 31. Thus, during use, it can be accessed from... Figure 3 Status (mutual contact) switched to Figure 4 In the above structure, the two movable seats 32 are separated, and their distal planes can contact the inclined surface of the mounting base 33, with the mounting base 33 bearing part of the pressure. Furthermore, in this structure, the angle between the inclined plane and the horizontal plane is no greater than 45°, and the inclination cannot be too small. If the inclination is too small, the mounting base 33 cannot bear the pressure of the component it is mounted on, easily leading to equipment damage. Therefore, the angle between the inclined plane and the horizontal plane is no less than 40°, which is achieved through the above structure. This ensures sufficient mounting strength for the mounting base 33 while allowing the inclined plane to bear the pressure of the movable seats 32, especially in the lower mold structure. Due to gravity, the lower mold drives the connected movable seats 32 to abut against the lower inclined surface of the mounting base 33, i.e., as shown... Figure 4 As shown, the movable seat 32 will maintain this state even if the drive structure does not apply any external force.

[0045] In addition to the opening and closing mechanism 3 mentioned above, based on the above structure, the two bases 2 have four connecting mechanisms 5 on their adjacent sides, each connected to a single movable base 32 and rotating synchronously. These connecting mechanisms 5 connect the mold 6 to the movable base 32. After connection, the mold 6 can move synchronously with the movable base 32, and the connected mold 6 can be rotated by driving the movable base 32. The specific structure of the connecting mechanism 5 is as follows:

[0046] The connecting mechanism 5 is used to fix the mold 6. The mold 6 includes an upper mold and a lower mold. The two ends of the upper mold are respectively connected to the connecting mechanism 5 located above, that is, connected to the connecting mechanism 5 connected to the higher movable seat 32 set on the same ring rail 31. The connection method can be bolt connection or welding, etc., as long as the purpose can be achieved. Correspondingly, the two ends of the lower mold are respectively connected to the connecting mechanism 5 located below, that is, connected to the connecting mechanism 5 connected to the lower movable seat 32 set on the same ring rail 31.

[0047] It should be noted that the side of the mold 6 closest to the ring rail 31 does not extend beyond the connecting mechanism 5 to avoid interference with the normal operation of the equipment. Furthermore, the two connecting mechanisms 5 located on the same side have a contact surface, which is also the contact surface of the two movable seats 32 on the same ring rail 31. The contact surface can also rotate around the ring rail 31, and the rotation axis passes through the center of the ring rail 31, that is, it is synchronized with the movable seats 32, so there will be no interference. In addition, the projection of the connecting mechanism 5 on the ring rail 31 does not cover the center of the ring rail 31.

[0048] In other words, the structural range of the connecting mechanism 5 has necessary design requirements. The connecting mechanism 5 must not affect the movement of the movable seat 32 to the position of abutting the mounting seat 33. During rotation, it is necessary to avoid any phenomena that affect rotation. Obviously, when one side of the connecting mechanism 5 is a plane, it cannot exceed the center of the circle. Figure 3 As shown, before the center of the circle, ensure that it can be further reached as... Figure 4 In the state shown, theoretically, the side of the connecting mechanism 5 closest to the mounting base 33 must be a plane unless otherwise designed. Designs that extend beyond the plane will increase the weight of the connecting mechanism 5 and affect rotation. Moreover, the plane should be on the same vertical plane as the center of the circle. In this case, the pressure on the movable base 32 is relatively small, and the pressure will gradually increase as the distance from the center of the circle increases.

[0049] Finally, the movable seats 32 of the two bases 2 are each driven by a separately provided drive mechanism 4, moving in opposite directions and synchronously. The drive mechanism 4 is located on the side opposite to the connecting mechanism 5, such as... Figure 1 As shown.

[0050] Based on the above structure, further, such as Figure 5 , 6 The specific structure of the drive mechanism 4 shown in Figures 7, 8, and 9 is as follows:

[0051] The guide wall 42 is concentric with the ring rail 31 and is arc-shaped, consisting of two sections. Each section of the guide wall 42 has a guide hole 43 through which a pull rope passes. A movable pull rope is provided on the outer side of the guide wall 42. The pull rope can move along the outer side of the guide wall 42. One end of the pull rope is used to fix the movable seat 32, and the other end is connected to a rotating wheel. Therefore, the pull rope can be moved by rotating the rotating wheel, and the movement of the pull rope can cause the movable seat 32 connected to it to be displaced. The track of the displacement is the ring rail 31. Each movable seat 32 is connected to at least two pull ropes, namely an opening pull rope 45 and a closing pull rope 47. The two pull ropes are fixed to the opening rotating wheel 44 and the closing rotating wheel 46, respectively. The opening rotating wheel 44 and the closing rotating wheel 46 rotate in the same direction and are driven by the same mechanism. The two rotating wheels can be driven to rotate synchronously and in opposite directions by clockwise and counterclockwise rotation, thereby realizing the movement of the movable seat 32 in two directions on the ring rail 31.

[0052] Furthermore, the aforementioned guide arms 42 are equipped with guide holes 43, including two symmetrically arranged guide holes located on the same horizontal plane, with the horizontal plane passing through the center of the ring rail. When pouring molten metal into the mold, it must remain horizontal, and the structure must be used to fix the mold's position to prevent misalignment of the movable seats. Additionally, each end of the guide arm 42 is equipped with a rotating wheel for steering the pull rope, ensuring the tension is lateral. Once the two movable seats 32 are in close contact, further tightening the pull rope will fix the position of the movable seats 32, keeping the mold horizontal.

[0053] It is important to note that the circumference of the wheel is greater than the arc length that a single movable seat 32 can move on the ring rail 31. That is, the winding length of the pull rope on the wheel is greater than or equal to 1 / 4 of the circumference of the ring rail 31. This ensures that the wheel can obtain a large stroke so that the single movable seat 32 can reach the designated position. Furthermore, the number of turns of the pull rope on the wheel does not exceed one turn. That is, the angle between the starting point and the ending point of the wheel's rotation and the center of the wheel is less than 360°. This ensures that the pull rope will not be wound more than one turn on the wheel. The purpose is to ensure that the release length and winding length of the two pull ropes that drive the same movable seat 32 at the same time are equal, thus avoiding the possibility of the pull rope breaking.

[0054] To drive the two movable seats 32 on the same ring rail 31, the above structure is symmetrically arranged in two sets, and the rotating wheels of the two movable seats 32 on the same side are both driven by the driven gear 49, and are respectively located on both sides of the drive rack 410, as shown below. Figure 7As shown, when the drive rack 410 moves left and right, it can drive the upper and lower sets of rotating wheels to move in opposite directions and at the same speed. A section of the drive rack 410 is provided with a guide and drive assembly 411 to ensure that the drive rack 410 moves in a lateral direction and has sufficient driving force.

[0055] like Figure 5-9 As shown, in the above structure, the guide wall 42 is provided on the first layer plate 41, and the second layer plate 48 is provided on the side of the first layer plate 41 away from the engagement mechanism 3. The pull rope and the wheel are both provided between the first layer plate 41 and the second layer plate 48. Then, the third layer plate 412 is provided on the side of the second layer plate 48 away from the first layer plate 41. The second layer plate 48 and the third layer plate 412 are provided with a driven gear 49, a drive rack 410 and a guide and drive assembly 411, and a fixing member 413 is provided that passes through the first layer plate 41, the second layer plate 48 and the third layer plate 412 and is connected to the mounting base 33 to complete the fixing.

[0056] In the above structure, the structure that fixes the pull rope to the movable seat 32 is as follows: both the first layer plate 41 and the second layer plate 48 are provided with arc-shaped grooves, and the arc-shaped grooves are provided corresponding to the pull rope. A drive connecting shaft 414 is provided to connect the pull rope and the movable seat 32 through, so that the movable seat 32 connected to it can move synchronously while the pull rope moves.

[0057] Finally, as Figure 1 As shown, the connecting mechanism 5 includes a connecting vertical plate 51 and a connecting horizontal plate. The connecting vertical plate 51 is rectangular, with one corner located at the center of the ring rail 31. The connecting vertical plate 51 is provided with a movable extension member 52, which can extend outward from the connecting vertical plate 51 in the adjacent plane direction. Under normal conditions, the movable extension member 52 is flush with the side of the connecting vertical plate 51 near the mounting base 33, and does not affect the normal rotation of the connecting vertical plate 51. However, when in the open state, such as Figure 4 As shown, the end of the movable extension 52 near the mounting base 33 extends out, and the extended surface is inclined. It can contact and be flush with the vertical plane of the mounting base 33, thereby preventing the connecting plate 51 from rotating counterclockwise and thus achieving a protective effect. In the event that the pull rope 45 fails, it can prevent the upper movable base 32 from slipping and causing an accident.
