Description

[0001] The invention relates to the technical field of casting, and in particular to an automatic core setting device for a vertical molding line and a use method thereof. Background Art

[0002] In the field of mechanical casting, molding machines are widely used. In order to meet the different molding requirements of various occasions, there are many types of molding machines. Traditionally, vertical parting molding machines are the most widely used. Different casting products have different molds. Some products have hollow cavities, so it is necessary to put the mud core into the corresponding position. After the metal material is cast into the mold, the cavity is formed. The production is carried out through molding, core setting, box closing, pouring, transfer, solidification and cooling.

[0003] The core setting process in casting plays a very important role in the entire product casting process and product quality.

[0019] S1: Initially, the first mold plate and the second mold plate are placed at both ends of the molding chamber respectively, and the molding chamber is filled with molding sand from the upper hopper, and then the first hydraulic cylinder and the second hydraulic cylinder are controlled to work, so that the first hydraulic cylinder drives the first mold plate to move into the molding chamber through the positive pressure plate, and the second hydraulic cylinder drives the second mold plate to move into the molding chamber through the reverse pressure plate. The positive pressure plate and the reverse pressure plate move relative to each other, so that the molding sand is compressed and formed into a casting. During this period, the staff can install the sand core on the movable seat except for the one directly above the second frame;

[0020] S2: Then the back pressure plate is driven to move out of the molding room by the second hydraulic cylinder, and then the back pressure plate is turned over by the third hydraulic cylinder, and then the mold in the molding room is pushed out by the positive pressure plate through the first hydraulic cylinder, and the positive pressure plate is further moved toward the second frame to cooperate with the mold pushed out subsequently, so that the mold forms a mold line on the second frame;

[0021] S3: After the third hydraulic cylinder drives the back pressure plate to flip, the back pressure plate touches the push switch of the limit plate, and the push switch controls the operation of the drive motor. The output shaft of the drive motor drives the sand core seat to rotate through the drive shaft and the connecting rod, so that the sand core seat will not hinder the casting pushed by the subsequent first hydraulic cylinder using the positive pressure plate, until each sand core seat moves to the position of the sand core seat adjacent to it;

[0022] S4: When the first hydraulic cylinder pushes the mold onto the second frame by using the positive pressure plate, the first hydraulic cylinder drives the positive pressure plate to reset and move back to one end of the molding chamber, and then the third hydraulic cylinder drives the counter pressure plate to reset and flip, and the second hydraulic cylinder drives the counter pressure plate to move to the other end of the molding chamber;

[0023] S5: When another sand core seat moves to the position of the sand core seat originally placed directly above the second frame, the driving motor stops running, and at this time the driven gear is no longer meshed with the fixed gear, the movable seat is reset under the elastic force of the elastic telescopic rod, and the pull rope of the reel is released, so that the movable seat drives the sand core to move toward the casting mold on the second frame. When the movable seat fits the casting mold, the abutment rod on the movable seat abuts against the casting mold, and the abutment rod is forced to push the swing rod to rotate with the rotating rod as the center, and the other end of the swing rod drives the movable plate to move, so that the movable plate pushes the sand core in the sand core groove into the casting cavity through the push block, completing the core setting action;

[0024] S6: Repeat S1-S5 to achieve continuous core setting action of the casting line.

[0025] Compared with the prior art, the present invention provides an automatic core setting device for a vertical molding line and a method for using the same, which has the following beneficial effects:

[0026] 1. The automatic core-setting device and use method of the vertical molding line avoids the risk of hands being pinched by the mold base plate by placing the sand core on the sand core seat on the side of the molding chamber, and a plurality of sand core seats placed in a circle are rotatably arranged, so that when one of the sand core seats is performing the core-setting action, the staff can have multiple and sufficient times to load the other sand core seats, so that the loading of the sand core seat is adapted to the pushing action of the mold plate, thereby ensuring the core-setting efficiency and effect.

[0027] 2. The automatic core-setting device and use method of the vertical molding line prevent the frame from affecting the rotation and loading of the sand core seat by setting an opening between the first frame and the second frame, and elastically set a rotating plate at the opening.

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0041] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0042] Example 1: Reference Figure 1-7 , an automatic core setting device for a vertical molding line, comprising a frame 1, and also comprising:

[0043] A vertical molding mechanism, which is arranged at the front side of the frame 1 and is used for molding sand;

[0044] An intermittent feeding assembly is arranged at the end of the vertical molding mechanism, and comprises a plurality of sand core seats 2 evenly distributed in a circumference and a driving member for driving the sand core seats 2 to rotate, so as to automatically lower the core into the mold cavity of the casting;

[0046] Specifically, the molding sand is compressed and formed into a casting mold through the vertical molding mechanism, and the casting mold is pushed to the second frame 102. When the molding sand is compressed, the staff can install the sand core on the sand core seat 2 except for the sand core seat 2 directly above the second frame 102 through the intermittent feeding assembly. By placing the sand core on the sand core seat 2 on the side of the frame 1, the risk of hands being pinched by the mold base plate is avoided. In addition, a plurality of sand core seats 2 arranged in a circle are rotatably arranged, so that when one of the sand core seats 2 is performing a core lowering action directly above the second frame 102, the staff can have multiple and sufficient times to load the other sand core seats 2, so that the loading of the sand core seat 2 is adapted to the pushing action of the vertical molding mechanism, thereby ensuring the core lowering efficiency and effect.

[0047] Example 2: Reference Figure 1-11 , an automatic core setting device for a vertical molding line, based on Example 1, further, the driving member includes a support plate 4 fixedly mounted on the first frame 101, a driving motor 401 is fixedly mounted on the support plate 4, the output shaft of the driving motor 401 passes through the support plate 4 and is connected to a driving shaft 402, and a connecting rod 403 is fixedly mounted on one end of the driving shaft 402 away from the driving motor 401, and the connecting rod 403 is fixedly connected to the sand core seat 2.

[0048] Furthermore, the sand core seat 2 includes a main seat body 201, a receiving groove 202 opened in the main seat body 201, a movable seat 203 movably arranged in the receiving groove 202, an elastic telescopic rod 204 arranged between the receiving groove 202 and the movable seat 203, and a sand core groove 205 opened on the side of the movable seat 203.

[0049] Furthermore, a sleeve 5 is fixedly provided on the outer side of the support plate 4, and the sleeve 5 is coaxially arranged with the driving shaft 402 and sleeved on the outer side of the driving shaft 402. A fixed gear 501 is fixedly provided on the sleeve 5. A rotating rod 6 is rotatably connected to the connecting rod 403, and a driven gear 601 meshing with the fixed gear 501 is provided on the rotating rod 6. A reel 602 is provided on the rotating rod 6, and a pull rope 6021 is wound around the reel 602. The end of the pull rope 6021 away from the reel 602 is connected to the movable seat 203.

[0050] Furthermore, a tooth gap 5011 is formed on the fixed gear 501 , and the fixed gear 501 is an incomplete gear. The fixed gear 501 is intermittently meshed with the driven gear 601 .

[0051] Furthermore, a rotating rod 2031 is rotatably connected inside the movable seat 203, a coil spring is arranged between the rotating rod 2031 and the movable seat 203, a swing rod 2032 is fixedly provided on the rotating rod 2031, both ends of the swing rod 2032 are slidably connected with sliders 2033, the two sliders 2033 are respectively connected with a movable plate 2034 and abutment rod 2035 that slide with the movable seat 203, and a push block 2036 that moves in the sand core groove 205 is fixedly provided on the movable plate 2034.

[0052] Specifically, the driving motor 401 is controlled to run so that the driving motor 401 drives each sand core seat 2 to rotate to the position of another sand core seat 2 adjacent to it. When one of the sand core seats 2 moves to the position of the sand core seat 2 originally placed directly above the second frame 102, the driving motor 401 stops running. At this time, the driven gear 601 on the rotating rod 6 connected to the sand core seat 2 is no longer engaged with the fixed gear 501, and the movable seat 203 is reset under the elastic force of the elastic telescopic rod 204. The drum 602 releases the pull rope 6021, so that the movable seat 203 drives the sand core to move toward the mold on the second frame 102. When the movable seat 203 fits the mold, the abutting rod 2035 on the movable seat 203 abuts against the mold, and the abutting rod 2035 is forced to push the swing rod 2032 to rotate with the rotating rod 2031 as the center of the circle. 032 The other end drives the movable plate 2034 to move, so that the movable plate 2034 pushes the sand core in the sand core groove 205 into the casting cavity through the pushing block 2036 to complete the core setting action. After the sand core seat 2 completes the core setting action, as the driving motor 401 continues to run, the sand core seat 2 leaves the top of the second frame 102. Before it repeatedly rotates to the top of the second frame 102 to perform the core setting action, the staff can have multiple and sufficient times to load the sand core seat 2 that has completed the core setting action when other sand core seats 2 are performing core setting operations, so that the loading of the sand core seat 2 adapts to the pushing action of the mold plate to ensure the core setting efficiency and effect; and the entire core setting action can realize the multi-position moving core setting action of the sand core through only one driving motor 401 driving source, which is simple to operate and reduces the installation cost of other driving equipment.

[0054] Specifically, when the rotating plate 3 is not subjected to force, its top surface is in the same plane as the top surfaces of the first frame 101 and the second frame 102, so as to support the mold pushed by the vertical molding mechanism, thereby preventing the mold from falling or getting stuck due to the opening 103 during the pushing process, thereby ensuring the normal progress of the automatic core-feeding process of the vertical molding production line. When the sand core seat 2 rotates, the rotating plate 3 is subjected to force to flip over the rotating axis 701 to avoid the movement of the sand core seat 2.

[0055] Example 4: Reference Figure 1-7 , an automatic core-setting device for a vertical molding line, based on Example 3, further, the vertical molding mechanism includes a molding chamber 8 fixedly mounted on a first frame 101, a hopper 801 is arranged on the top of the molding chamber 8, and a first extrusion member and a second extrusion member are arranged on both sides of the molding chamber 8, respectively, the first extrusion member includes a support 9 fixedly mounted on the top of the first frame 101, a first hydraulic cylinder 901 is fixedly mounted on the support 9, a positive pressure plate 902 is fixedly mounted at the end of the first hydraulic cylinder 901, a first mold plate 903 is fixedly mounted on the positive pressure plate 902, the second extrusion member includes a second hydraulic cylinder 10 fixedly mounted on the outside of the molding chamber 8, a moving frame 1001 is fixedly mounted at the end of the second hydraulic cylinder 10, a back pressure plate 111 driven by a third hydraulic cylinder 11 is rotatably mounted on the moving frame 1001, and a second mold plate 112 matching the first mold plate 903 is fixedly mounted on the back pressure plate 111.

[0056] Furthermore, a limit plate 12 is disposed on the moving frame 1001 , and a pressing switch 121 electrically connected to the driving motor 401 is disposed on the limit plate 12 .

[0057] Specifically, initially, the first mold plate 903 and the second mold plate 112 are respectively placed at the two ends of the molding chamber 8, and the molding chamber 8 is filled with molding sand from the upper hopper 801, and then the first hydraulic cylinder 901 and the second hydraulic cylinder 10 are controlled to work, so that the first hydraulic cylinder 901 drives the first mold plate 903 to move into the molding chamber 8 through the positive pressure plate 902, and the second hydraulic cylinder 10 drives the second mold plate 112 to move into the molding chamber 8 through the back pressure plate 111, and the positive pressure plate 902 and the back pressure plate 111 move relative to each other to compress the molding sand and form a casting. During this period, the staff can install the sand core on the movable seat 203 except for the one directly above the second frame 102, and then drive the back pressure plate 111 to move into the molding chamber through the second hydraulic cylinder 10. 8 moves outward, and then the back pressure plate 111 is driven to flip through the third hydraulic cylinder 11, and then the casting mold in the molding chamber 8 is pushed out by the positive pressure plate 902 through the first hydraulic cylinder 901, and the positive pressure plate 902 is further moved toward the second frame 102, and the casting mold pushed subsequently is cooperated with to form a casting line on the second frame 102.

It should be noted that the back pressure plate 111 is an integrated structure composed of a vertical plate and an inclined plate, and the arrangement of the inclined plate facilitates the third hydraulic cylinder 11 to push the back pressure plate 111 to flip.

[0058] The present invention also discloses a method for using an automatic core setting device for a vertical molding line, comprising the following steps:

[0059] S1: Initially, the first mold plate 903 and the second mold plate 112 are placed at both ends of the molding chamber 8, respectively. The molding chamber 8 is filled with molding sand from the upper hopper 801. Then, the first hydraulic cylinder 901 and the second hydraulic cylinder 10 are controlled to work, so that the first hydraulic cylinder 901 drives the first mold plate 903 to move into the molding chamber 8 through the positive pressure plate 902, and the second hydraulic cylinder 10 drives the second mold plate 112 to move into the molding chamber 8 through the reverse pressure plate 111. The positive pressure plate 902 and the reverse pressure plate 111 move relative to each other, so that the molding sand is compressed and formed into a casting. During this period, the staff can install the sand core on the movable seat 203 except for the one directly above the second frame 102.

[0060] S2: The second hydraulic cylinder 10 then drives the back pressure plate 111 to move out of the molding chamber 8, and then the third hydraulic cylinder 11 drives the back pressure plate 111 to flip, and then the first hydraulic cylinder 901 uses the positive pressure plate 902 to push the mold in the molding chamber 8 out, and the positive pressure plate 902 further moves toward the second frame 102, and cooperates with the mold pushed out later, so that the mold forms a mold line on the second frame 102;

[0061] S3: After the third hydraulic cylinder 11 drives the back pressure plate 111 to flip, the back pressure plate 111 touches the push switch 121 of the limit plate 12, and the push switch 121 controls the driving motor 401 to operate. The output shaft of the driving motor 401 drives the sand core seat 2 to rotate through the driving shaft 402 and the connecting rod 403, so that the sand core seat 2 will not hinder the casting pushed by the subsequent first hydraulic cylinder 901 using the positive pressure plate 902, until each sand core seat 2 moves to the position of the sand core seat 2 adjacent to it;

[0062] S4: When the first hydraulic cylinder 901 pushes the mold onto the second frame 102 by using the positive pressure plate 902, the first hydraulic cylinder 901 drives the positive pressure plate 902 to reset and move back to one end of the molding chamber 8, and then the third hydraulic cylinder 11 drives the back pressure plate 111 to reset and flip, and the second hydraulic cylinder 10 drives the back pressure plate 111 to move to the other end of the molding chamber 8;

[0063] S5: When another sand core seat 2 moves to the position of the sand core seat 2 originally placed directly above the second frame 102, the driving motor 401 stops running, and at this time the driven gear 601 is no longer meshed with the fixed gear 501, and the movable seat 203 is reset under the elastic force of the elastic telescopic rod 204, and the drum 602 releases the pull rope 6021, so that the movable seat 203 drives the sand core to move toward the casting mold on the second frame 102. When the movable seat 203 fits the casting mold, the abutment rod 2035 on the movable seat 203 abuts against the casting mold, and the abutment rod 2035 is forced to push the swing rod 2032 to rotate with the rotating rod 2031 as the center, and the other end of the swing rod 2032 drives the movable plate 2034 to move, so that the movable plate 2034 pushes the sand core in the sand core groove 205 into the casting cavity through the push block 2036, completing the core lowering action;

[0064] S6: Repeat S1-S5 to achieve continuous core setting action of the casting line.

5. A method for using the automatic core setting device for a vertical molding line according to claim 4, characterized in that: The following steps are involved: S1: Initially, the first mold plate (903) and the second mold plate (112) are respectively placed at the two ends of the molding chamber (8), and the molding chamber (8) is filled with molding sand from the upper hopper (801). Subsequently, the first hydraulic cylinder (901) and the second hydraulic cylinder (10) are controlled to work, so that the first hydraulic cylinder (901) drives the first mold plate (903) to move into the molding chamber (8) through the positive pressure plate (902), and the second hydraulic cylinder (10) drives the second mold plate (112) to move into the molding chamber (8) through the reverse pressure plate (111). The positive pressure plate (902) and the reverse pressure plate (111) move relative to each other, so that the molding sand is compressed and formed into a casting. During this period, the staff can install the sand core on the movable seat (203) except for the one directly above the second frame (102); S2: The back pressure plate (111) is then driven to move out of the molding chamber (8) by the second hydraulic cylinder (10), and then the back pressure plate (111) is driven to flip by the third hydraulic cylinder (11), and then the casting mold in the molding chamber (8) is pushed out by the positive pressure plate (902) through the first hydraulic cylinder (901), and the positive pressure plate (902) is further moved toward the second frame (102), and cooperates with the casting mold pushed out subsequently, so that the casting mold forms a casting line on the second frame (102); S3: After the third hydraulic cylinder (11) drives the back pressure plate (111) to flip, the back pressure plate (111) contacts the push switch (121) of the limit plate (12), and the push switch (121) controls the driving motor (401) to operate. The output shaft of the driving motor (401) drives the sand core seat (2) to rotate via the driving shaft (402) and the connecting rod (403), so that the sand core seat (2) will not hinder the casting mold pushed by the subsequent first hydraulic cylinder (901) using the positive pressure plate (902), until each sand core seat (2) moves to the position of the sand core seat (2) adjacent to it; S4: When the first hydraulic cylinder (901) uses the positive pressure plate (902) to push the mold onto the second frame (102), the first hydraulic cylinder (901) drives the positive pressure plate (902) to reset and move back to one end of the molding chamber (8), and then the third hydraulic cylinder (11) drives the back pressure plate (111) to reset and flip, and the second hydraulic cylinder (10) drives the back pressure plate (111) to move to the other end of the molding chamber (8); S5: When the other sand core seat (2) moves to the position of the sand core seat (2) originally placed directly above the second frame (102), the driving motor (401) stops running, and at this time the driven gear (601) is no longer meshed with the fixed gear (501), the movable seat (203) is reset under the elastic force of the elastic telescopic rod (204), and the reel (602) releases the pull rope (6021), so that the movable seat (203) drives the sand core to the casting on the second frame (102). The mold moves, when the movable seat (203) fits with the mold, the abutting rod (2035) on the movable seat (203) abuts against the mold, and the abutting rod (2035) is forced to push the swing rod (2032) to rotate with the rotating rod (2031) as the center, and the other end of the swing rod (2032) drives the movable plate (2034) to move, so that the movable plate (2034) pushes the sand core in the sand core groove (205) into the mold cavity through the pushing block (2036), completing the core setting action; S6: Repeat S1-S5 to achieve continuous core setting action of the casting line.
