Description

Technical Field

[0001] This utility model belongs to the field of casting equipment technology, specifically a locking mechanism for die casting molds. Background Technology

[0002] The basic process of die casting involves first casting molten metal into the cavity of a mold at low or high speed. The mold has a movable cavity surface, which is pressurized and forged as the molten metal cools. This process eliminates shrinkage cavities and porosity defects in the blank and also allows the internal structure of the blank to reach the forged state with broken grains.

[0003] Currently, operators frequently use die-casting molds when casting metal. However, while existing die-casting molds possess basic die-casting functions, the lack of a mold-locking mechanism causes slight wobbling of the moving mold during the die-casting process, which can affect the quality of subsequent products. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the above problems by providing a mold locking mechanism for a die-casting mold, which has the advantage of stabilizing die casting.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a locking mechanism for a die-casting mold, comprising a fixed mold, a connecting frame fixedly connected to the top of the fixed mold, a first pneumatic cylinder fixedly connected to the top of the connecting frame, a movable mold fixedly connected to the bottom of the first pneumatic cylinder, and movable blocks located inside the fixed mold fixedly connected to both sides of the bottom of the movable mold, the movable blocks being slidably inserted into the top of the fixed mold;

[0006] A servo motor is fixedly installed below the fixed mold. A rotating shaft is fixedly sleeved on the output shaft of the servo motor. A horizontally arranged long rod is fixedly sleeved on the outer surface of the rotating shaft. Both ends of the long rod are hinged to moving rods. The other ends of the two moving rods are hinged to long blocks. Moving plates located on both sides of the fixed mold are fixedly connected to the two long blocks respectively. The moving plates are vertically arranged and have an insert block fixedly connected to their top ends. The other end of the insert block is slidably inserted into the side wall of the fixed mold and can pass through the positioning hole on the moving block.

[0007] As a preferred embodiment of this invention, a guide block located inside the fixed mold is fixedly connected to the long block, and the guide block is slidably connected to the bottom of the fixed mold.

[0008] As a preferred embodiment of this utility model, a placement plate is provided inside the top of the fixed mold, and a second pneumatic cylinder located inside the fixed mold is fixedly connected to the bottom end of the placement plate. Table legs are fixedly installed at the four corners of the bottom end of the fixed mold, and a collection groove is movably connected to the inside of the front of the fixed mold.

[0009] As a preferred embodiment of this utility model, a limiting block located inside the connecting frame is fixedly connected to one side of the moving mold, and the limiting block is slidably connected to the connecting frame. An inlet is fixedly connected to the other side of the moving mold, and the inlet passes through the moving mold and the connecting frame in sequence and extends to the outside of the connecting frame.

[0010] In a preferred embodiment of this invention, the top end of the fixed mold is movably connected to a movable plate located behind the moving mold, and the top end of the fixed mold is fixedly connected to a connecting plate located behind the movable plate. Round rods are fixedly connected to both sides of the movable plate, and the other end of each round rod passes through the connecting plate and extends to the outside of the back of the connecting plate, where a short block is fixedly connected.

[0011] A drive motor is fixedly installed at the bottom of the back of the fixed mold, and a rotating shaft is fixedly sleeved on the output shaft of the drive motor.

[0012] A hollow block is fixedly connected to the top end of the rotating shaft. The hollow block has a strip-shaped hole, and a movable and rotatable circular shaft is provided in the strip-shaped hole. The top end of the circular shaft is fixedly connected to the bottom end of the short block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up a servo motor, a long rod, a long block, a moving plate, and an insert block, allows the operator to start the servo motor, which will cause the rotating shaft and the long rod to rotate. This causes the two moving rods to move in opposite directions through the two long blocks and the two moving plates. As a result, the two insert blocks can pass through the two moving blocks and be inserted into the interior of the fixed mold, thereby locking the two moving blocks and the moving mold as a whole. This prevents the moving mold from slightly shaking during subsequent die-casting operations, which could affect the final quality of the product.

[0015] 2. This utility model, by setting up a movable plate, a round rod, a drive motor, a rotating shaft, and a hollow block, allows the operator to start the drive motor, which will cause the rotating shaft and the hollow block to rotate. This causes the inner surface of the hollow block to press and push the outer surface of the round shaft, which in turn causes the round shaft to drive the short block, the two round rods, and the movable plate forward. This allows the movable plate to push the finished metal mold into the collection tank, thereby effectively reducing the time the operator spends collecting the finished metal.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5 As shown, this utility model provides a locking mechanism for a die-casting mold, including a fixed mold 1, a connecting frame 2 fixedly connected to the top of the fixed mold 1, a first pneumatic cylinder 3 fixedly connected to the top of the connecting frame 2, a moving mold 4 fixedly connected to the bottom of the first pneumatic cylinder 3, and movable blocks 5 located inside the fixed mold 1 fixedly connected to the left and right sides of the bottom of the moving mold 4, and the movable blocks 5 are slidably inserted into the top of the fixed mold 1.

[0024] A servo motor 6 is fixedly installed at the front of the bottom end of the fixed mold 1. A rotating shaft 7 is fixedly sleeved at the other end of the output shaft of the servo motor 6. A horizontally arranged long rod 8 is fixedly sleeved on the outer surface of the rotating shaft 7. A moving rod 9 is hinged to both the front and rear ends of the long rod 8. A long block 10 is hinged to the other end of the moving rod 9. There are two long blocks 10. The moving rod 9 and the long blocks 10 form a double linkage structure. The top ends of the two long blocks 10 are respectively fixedly connected to moving plates 11 located on the left and right sides of the fixed mold 1. The moving plates 11 are vertically arranged. An insert block 12 is fixedly connected to the top of the inner side. The other end of the insert block 12 is slidably inserted into the side wall of the fixed mold 1 and can pass through the movable block 5.

[0025] When the operator starts the servo motor 6, the rotating shaft 7 and the long rod 8 will rotate. This will cause the two moving rods 9 to move in opposite directions through the two long blocks 10, which in turn cause the two moving plates 11 to move towards each other. This will allow the two insert blocks 12 to pass through the two movable blocks 5 and be inserted into the interior of the fixed mold 1, thereby locking the two movable blocks 5 and the moving mold 4 as a whole, thus preventing the moving mold 4 from shaking slightly in subsequent operations.

[0026] Each of the two elongated blocks 10 has a guide block 13 fixedly connected to its top end, located inside the fixed mold 1. The outer surface of the guide block 13 is slidably connected to the bottom of the fixed mold 1. Due to the design of the two guide blocks 13, the movement of the two elongated blocks 10 can be effectively limited.

[0027] The fixed mold 1 has a placement plate 15 internally connected to its top, and a second pneumatic cylinder 14 located inside the fixed mold 1 is fixedly connected to the bottom of the placement plate 15. Table legs 27 are fixedly installed at the four corners of the bottom of the fixed mold 1, and a collection trough 18 is internally connected to the front of the fixed mold 1. When the operator starts the second pneumatic cylinder 14, the placement plate 15 will move upward.

[0028] The moving mold 4 has a fixedly connected limiting block 16 located inside the left end of the connecting frame 2. The outer surface of the limiting block 16 slides against the connecting frame 2. The right side of the moving mold 4 has a fixedly connected inlet 17. The right end of the inlet 17 passes through the moving mold 4 and the connecting frame 2 and extends to the outside of the right side of the connecting frame 2. Due to the design of the limiting block 16, the movement of the moving mold 4 can be well guided.

[0029] The fixed mold 1 has a movable plate 19 movably connected to its top end, located behind the moving mold 4. The fixed mold 1 also has a connecting plate 20 fixedly connected to its top end, located behind the movable plate 19. Round rods 21 are fixedly connected to both the left and right sides of the back of the movable plate 19. The other end of each round rod 21 passes through the connecting plate 20 and extends to the outside of the back of the connecting plate 20, where a short block 22 is fixedly connected. When the short block 22 moves the round rod 21, it causes the movable plate 19 to move forward.

[0030] A drive motor 23 is fixedly mounted on the bottom of the back of the fixed mold 1. A rotating shaft 24 is fixedly sleeved on the other end of the output shaft of the drive motor 23. When the operator starts the drive motor 23, the rotating shaft 24 will rotate. A hollow block 25 is fixedly connected to the top of the rotating shaft 24. The hollow block 25 has a strip-shaped hole, and a movable and rotatable round shaft 26 is placed in the strip-shaped hole. The top of the round shaft 26 is fixedly connected to the bottom of the short block 22, forming a crank-slider mechanism together with the round rod 21 and the rotating shaft 24. When the rotating shaft 24 drives the hollow block 25 to move, the inner surface of the hollow block 25 will press and push the outer surface of the round shaft 26, thereby causing the round shaft 26 to drive the short block 22 forward.

[0031] Working principle and usage process of this utility model:

[0032] First, the operator operates the first pneumatic cylinder 3, which causes the moving mold 4 to move downwards. When the bottom of the moving mold 4 is in contact with the top of the fixed mold 1 and the two movable blocks 5 move into the interior of the fixed mold 1, the operator starts the servo motor 6, which causes the rotating shaft 7 and the long rod 8 to rotate. This causes the two moving rods 9 to move towards the two insert blocks 12 via the two long blocks 10, which in turn causes the two moving plates 11 to move towards the two insert blocks 12. This allows the two insert blocks 12 to pass through the two movable blocks 5 and insert into the interior of the fixed mold 1, thus locking the two movable blocks 5 and the moving mold 4 together. This prevents the moving mold 4 from slightly shaking during the subsequent die-casting operation, which could affect the final molding quality of the product. Then, the operator can add molten metal liquid into the interior of the moving mold 4 through the feed port 17 to perform the die-casting operation.

[0033] Finally, after the molten metal inside the moving mold 4 and the fixed mold 1 cools and solidifies, the operator runs the servo motor 6 and the first pneumatic cylinder 3 again. The operation of the servo motor 6 causes the rotating shaft 7 and the long rod 8 to rotate, causing the two moving rods 9 to move in opposite directions via the two long blocks 10, which in turn causes the two moving plates 11 to move the two insert blocks 12. This allows the two insert blocks 12 to disengage from the two moving blocks 5, thus releasing the locking effect on the moving mold 4. Meanwhile, the operation of the first pneumatic cylinder 3 causes the moving mold 4 to move upwards. At this point, the operator runs the second... The operation of the first pneumatic cylinder 14 and the drive motor 23 causes the top of the placement plate 15 to move to the outer surface of the top of the fixed mold 1, thereby ejecting the finished metal. The operation of the drive motor 23 causes the rotating shaft 24 and the hollow block 25 to rotate, thereby causing the inner surface of the hollow block 25 to squeeze and push the outer surface of the round shaft 26. This causes the round shaft 26 to drive the short block 22, the two round rods 21 and the movable plate 19 to move forward, thereby allowing the movable plate 19 to push the finished metal into the collection tank 18, thus completing the collection operation.
