Description

Technical Field

[0001] This utility model belongs to the technical field of mold fixing equipment, and in particular, a mold fixing frame for casting. Background Technology

[0002] When pouring molten iron into existing casting molds, the large weight makes them prone to collisions, affecting the quality of the castings. Therefore, a fixing frame is required. However, the existing fixing frame uses electric push rods to provide power when fixing the mold, which causes energy consumption and is not conducive to the energy saving and environmental protection of the fixing frame. On the other hand, using multiple sets of bolts for fixing reduces the ease of use of the fixing frame.

[0003] A search of related technologies revealed a Chinese patent document (authorization announcement number CN221848637U) entitled "A Casting Mold Fixing Device," comprising a base, a support structure, and an extrusion structure. The support structure is mounted on the base, and the extrusion structure is mounted on the support structure. The support structure includes a mounting seat, a pull rod, a support platform, and a limiting post. The mounting seat is welded to the base, the pull rod is threaded onto the mounting seat, the support platform is welded to the base, and the limiting post is welded to the support platform. This utility model belongs to the technical field of mold fixing equipment, specifically referring to a casting mold fixing frame. It effectively solves the problem that most mold fixing frames on the market currently use external heavy objects for pressure fixing. During casting, due to the large weight of molten iron, collisions are prone to occur, causing the mold to tilt and the casting to twist, affecting product quality. However, this fixing frame does not consider the energy consumption caused by using electric push rods for power, which is not conducive to the energy saving and environmental protection of the fixing frame. Furthermore, using multiple sets of bolts for fixing reduces the ease of use of the fixing frame. Utility Model Content

[0004] The purpose of this utility model is to provide a mold fixing bracket for casting to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold fixing bracket for casting, comprising:

[0006] A placement platform for placing casting molds, with four mounting plates arranged in an array on the bottom surface of the placement platform, and mounting ears connected to the sides of the mounting plates.

[0007] A fixing assembly for fixing a casting mold includes two limiting frames and two L-shaped limiting plates. The inner sidewalls of the limiting frames are slidably connected to the limiting plates. An extrusion frame for fixing the casting mold is connected to the adjacent side of the two limiting plates. A connecting plate is connected to the bottom surface of the two limiting plates. A threaded sleeve is rotatably connected to the top surface of the connecting plate. Two limiting rings are sleeved on the side of the threaded sleeve. The adjacent side of the two limiting rings is in rotatable frictional contact with the connecting plate. A threaded rod is threadedly connected to the threaded sleeve. The top surface of the threaded rod is connected and fixed to the placement platform.

[0008] Preferably, the extrusion frame is located on the upper part of the placement platform, and the two limiting frames are connected and fixed to the placement platform on adjacent sides.

[0009] Preferably, the lower limiting ring is connected to four radially arranged push plates on its side, and the top surface of the placement platform is provided with four positioning components arranged in an array for positioning the casting mold.

[0010] Preferably, the positioning assembly includes positioning sleeves and positioning posts for positioning the casting mold, with the top surface of the placement platform being embedded and fixedly connected to the four positioning sleeves.

[0011] Preferably, the top surfaces of the four positioning sleeves are flush with the top surface of the placement platform, and the inner cavities of the positioning sleeves are slidably connected to the positioning posts.

[0012] Preferably, the bottom surface of the positioning sleeve is connected to a hollow connecting rod, and a moving block is slidably connected to the inner cavity of the connecting rod.

[0013] Preferably, the bottom surface of the positioning column is connected and fixed to the connecting rod and the moving block through it, and two through grooves are opened on the side of the connecting rod, with limit blocks slidably connected to the inner wall of the through grooves of the connecting rod.

[0014] Preferably, the two limiting blocks are connected to the moving block on their adjacent sides, and one of the limiting blocks has a positioning bolt threadedly connected to its side, with the head of the positioning bolt abutting against the connecting rod.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] This casting mold fixing bracket allows the casting mold to be placed on the top surface of the placement platform. Pushing the push plate rotates the screw threaded sleeve during transmission, causing it to move along the threaded path of the screw rod. Adjusting the vertical position of the connecting plate, and with the connection of the limiting plate, adjusts the vertical position of the extrusion frame. The extrusion frame, in conjunction with the placement platform, clamps and fixes the casting mold placed on the top surface of the placement platform, preventing collisions due to its large weight that could affect the quality of the casting. It eliminates the need for an electric push rod, achieving energy efficiency and environmental friendliness. Furthermore, it eliminates the need for multiple sets of bolts for fixing, enhancing the ease of use of the fixing bracket.

[0017] When the casting mold is placed on the top surface of the placement platform, the positioning pins of the four positioning components are embedded in the positioning grooves of the casting mold to position it. Since it is inconvenient for the four positioning pins to extend into the positioning grooves of the casting mold for positioning, the positioning bolts of one of the positioning components are released to fix the position of the limiting block, allowing the moving block to move upward along the inner cavity of the connecting rod. During the transmission process, the positioning pins move downward and upward along the driving path of the positioning sleeve, so that the top surface of one positioning pin is higher than the top surfaces of the other three positioning pins, making it easier for the positioning pins to extend into the positioning grooves of the casting mold, thereby improving the ease of use of the fixing frame.

However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0026] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0027] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0028] Please see Figures 1 to 4 A mold fixing bracket for casting, in this embodiment including:

[0029] A placement platform 1 for placing casting molds is provided. Four mounting plates 11 arranged in an array are connected to the bottom surface of the placement platform 1. Mounting ears 12 are connected to the sides of the mounting plates 11. Threaded grooves are provided on the top surface of the mounting ears 12. Bolts are threaded into the threaded grooves of the mounting ears 12. The mounting ears 12 are installed and fixed by bolts to install and fix the fixing frame.

[0030] A fixing component 2 for fixing a casting mold includes two limiting frames 3 and two L-shaped limiting plates 4. The two limiting plates 4 drive the inner sidewalls to be arranged concentrically. The inner sidewalls of the limiting frames 3 are slidably connected to the limiting plates 4. An extrusion frame 5 for fixing the casting mold is connected to the adjacent side of the two limiting plates 4. A connecting plate 6 is connected to the bottom surface of the two limiting plates 4. A threaded sleeve 7 is rotatably connected to the top surface of the connecting plate 6. Both ends of the threaded sleeve 7 pass through the connecting plate 6. Two limiting rings 9 are sleeved on the side of the threaded sleeve 7. The inner ring surfaces of the two limiting rings 9 are connected and fixed to the threaded sleeve 7. The top surface of the upper limiting ring 9 is flush with the top surface of the threaded sleeve 7, and the bottom surface of the lower limiting ring 9 is flush with the bottom surface of the threaded sleeve 7. The adjacent side of the two limiting rings 9 is in rotatable frictional contact with the connecting plate 6. A threaded rod 8 is threadedly connected to the threaded sleeve 7. The top surface of the threaded rod 8 is connected and fixed to the placement platform 1.

[0031] The extrusion frame 5 is located on the upper part of the placement platform 1. Two limiting frames 3 are connected and fixed to the placement platform 1 on adjacent sides. Four radially arranged push plates 10 are connected to the side of the lower limiting ring 9. The top surface of the placement platform 1 is provided with four positioning components 13 arranged in an array for positioning the casting mold. The positioning component 13 includes a positioning sleeve 14 and a positioning post 15 for positioning the casting mold. The top surface of the placement platform 1 is embedded and fixedly connected to the four positioning sleeves 14. The top surface of the four positioning sleeves 14 is flush with the top surface of the placement platform 1. The inner cavity of the positioning sleeve 14 is slidably connected to the positioning post 15. The bottom surface of the casting mold will have four openings. A positioning groove is provided for the insertion of four positioning pins 15, so that the four positioning pins 15 can be positioned and fixed for casting mold. The bottom surface of the positioning sleeve 14 is connected to a hollow connecting rod 16. The inner cavity of the connecting rod 16 is slidably connected to a moving block 17. The bottom surface of the positioning pin 15 passes through the connecting rod 16 and is connected and fixed to the moving block 17. Two through slots are opened on the side of the connecting rod 16. Limiting blocks 18 are slidably connected to the inner wall of the through slots of the connecting rod 16. The two limiting blocks 18 are connected to the moving block 17 on their adjacent sides. One of the limiting blocks 18 is threadedly connected to a positioning bolt 19 on its side. The head of the positioning bolt 19 abuts against the connecting rod 16.

[0032] In order to horizontally position the casting mold, when the casting mold is placed on the top surface of the placement platform 1, the four positioning grooves on the bottom surface of the casting mold are used to fix the casting mold in a horizontal position to prevent the casting mold from shaking or shifting on the top surface of the placement platform 1.

[0033] To vertically position the casting mold, the four push plates 10 are rotated around the lower limit rings 9 as the axis. Under the connection of the limit rings 9, the threaded sleeve 7 is rotated and moves along the thread path of the threaded rod 8. Under the fixed restriction of the two limit rings 9, the connecting plate 6 is moved vertically. At the same time, the two limit plates 4 move vertically along the path of the limit frame 3, adjusting the vertical position of the extrusion frame 5. During the downward movement of the extrusion frame 5, it cooperates with the placement table 1 to vertically clamp and fix the casting mold.

[0034] To facilitate the extension of the positioning pin 15 into the positioning groove of the casting mold, the position fixing of one of the positioning bolts 19 to the limiting block 18 is released, allowing the moving block 17 to move vertically along the inner cavity of the connecting rod 16. The vertical height of the positioning pin 15 is adjusted so that the top surface of one positioning pin 15 is higher than the top surfaces of the other three positioning pins 15. The positioning sleeve 14 is set to fix the vertical movement path of the positioning pin 15, enhancing the vertical movement stability of the positioning pin 15. This facilitates the extension of the higher positioning pin 15 into the positioning groove of the casting mold for initial positioning of the casting mold. The casting mold is then rotated around this positioning pin 15 as the axis, aligning the three positioning grooves of the casting mold with the other three positioning pins 15. After the other three positioning pins 15 extend into the positioning groove of the casting mold, the position of the casting mold is further fixed, facilitating the extension of all four positioning pins 15 into the positioning groove of the casting mold and improving the ease of use of the fixing frame.

[0035] Working principle

[0036] When using this casting mold fixing frame, the user can release one of the positioning bolts 19 from fixing the position of the limiting block 18, and the moving block 17 can move along the inner cavity of the connecting rod 16, driving the positioning column 15 to move along the inner cavity of the positioning sleeve 14, adjusting the height of one of the positioning columns 15 so that the top surface of one of the positioning columns 15 is higher than the top surfaces of the other three positioning columns 15.

[0037] Positioning pins 15 are inserted into the positioning grooves of the casting mold placed on the top surface of the placement platform 1 to position and fix the casting mold.

[0038] The push plate 10 is rotated around the limiting ring 9, causing the threaded sleeve 7 to move down along the threaded path of the threaded rod 8, causing the connecting plate 6 to move down. Under the connecting action of the limiting plate 4, the extrusion frame 5 moves down and, in conjunction with the placement table 1, clamps and fixes the casting mold. The limiting plate 4 moves vertically down along the path of the limiting frame 3, allowing the extrusion frame 5 to move smoothly vertically.
