Description

Technical Field

[0001] This utility model relates to the field of material processing technology, and in particular to a sheet metal die-casting mold that facilitates demolding. Background Technology

[0002] Die casting molds are tools used in the metal die casting process, which is mainly used for the mass production of metal parts with complex shapes, high precision, and good surface finish.

[0003] Traditional die-casting molds are usually equipped with automatic demolding devices. However, these devices are not suitable for processing small die-cast parts due to their large size. As a result, operators must manually intervene to remove the finished parts. This manual operation not only increases labor intensity and reduces production efficiency, but may also cause scratches or damage to the surface of the parts, thereby affecting product quality.

[0004] The problem mentioned above requires a die-casting mold for sheet metal that facilitates demolding. Utility Model Content

[0005] To overcome the drawbacks of manual demolding, this utility model provides a sheet metal die-casting mold that facilitates demolding.

[0006] The technical implementation scheme of this utility model is as follows: a sheet metal die-casting mold for easy demolding includes a base, a mounting frame, a hydraulic rod, a die-casting plate, and a mold frame. The mounting frame is installed on the base, and the hydraulic rod is installed on the mounting frame. The extension end of the hydraulic rod is connected to the die-casting plate. The mold frame is installed on the top of the base. It also includes connecting rods, connecting plates, a top plate, springs, mounting plates, a first bidirectional lead screw, a first guide rod, and extrusion frames. The mold frame is symmetrically connected to the left and right sides with front and rear distributed connecting rods. A connecting plate is connected between two connecting rods on the same side. A top plate is connected between the tops of the two connecting plates. Each connecting rod is connected to the mold frame with a spring. Mounting plates are symmetrically installed on the mounting frame. A first bidirectional lead screw is rotatably connected between the two mounting plates. A first guide rod is connected between the two mounting plates. Extrusion frames are symmetrically threaded on the first bidirectional lead screw. The two extrusion frames slide with the first guide rod.

[0007] As a further preferred embodiment, it also includes connecting blocks, a second guide rod, a second bidirectional lead screw, a limiting plate, a motor, a first bevel gear, and a second bevel gear. Connecting blocks are symmetrically connected to the base, with the second guide rod connected to the two rear connecting blocks and the second bidirectional lead screw rotatably connected to the two front connecting blocks. The limiting plate is symmetrically threaded onto the second bidirectional lead screw, and the limiting plate slides with the second guide rod. A motor is mounted on the base, with the first bevel gear connected to the motor output shaft and the second bevel gear connected to the second bidirectional lead screw. The first bevel gear and the second bevel gear mesh.

[0008] As a further preferred embodiment, it also includes a rotating handle that passes through the rear mounting plate and is connected to the first bidirectional lead screw.

[0009] As a further preferred option, it also includes protective pads, with protective pads connected to the inner sides of the two limiting plates.

[0010] As a further preferred option, the inner surfaces of the two extrusion frames are beveled.

[0011] As a further preferred option, the mold frame is provided with a groove that matches the size of the top plate.

[0012] The beneficial effects of this utility model are as follows: 1. By setting up a connecting rod, connecting plate, top plate, spring, mounting plate, first bidirectional lead screw, first guide rod, and extrusion frame, after the die-casting process is completed, when the hydraulic rod retracts and drives the die-casting plate to reset, the four springs will automatically push the top plate upward, thereby lifting the die-cast plate. This greatly simplifies the demolding process, reduces the need for manual intervention, and improves production efficiency. For heavier plates, if the springs alone cannot achieve effective demolding, the operator can rotate the handle to drive the first bidirectional lead screw to rotate, causing the extrusion frame to move inward along the first guide rod, using its inclined surface to lift the plate. This ensures that even heavy plates can be demolded smoothly, enhancing the applicability and flexibility of the equipment.

[0013] 2. By setting up a connecting block, a second guide rod, a second bidirectional lead screw, a limiting plate, a motor, a first bevel gear, and a second bevel gear, after the plate is placed, the motor drives the first bevel gear to rotate, thereby limiting the plate with two limiting plates, preventing the plate from shifting or deviating during the die-casting process, and ensuring processing accuracy and stability.

[0023] Example: A sheet metal die-casting mold for easy demolding, such as... Figures 1-7As shown, the assembly includes a base 1, a mounting bracket 2, a hydraulic rod 3, a die-casting plate 4, a mold frame 5, a connecting rod 6, a connecting plate 7, a top plate 8, a spring 9, a mounting plate 10, a first double-acting lead screw 11, a first guide rod 12, an extrusion frame 13, a connecting block 14, a second guide rod 15, a second double-acting lead screw 16, a limiting plate 17, a motor 18, a first bevel gear 19, a second bevel gear 20, a rotating handle 21, and a protective pad 22. The mounting bracket 2 is mounted on the base 1, and the hydraulic rod 3 is mounted on the mounting bracket 2. The telescopic end of the hydraulic rod 3 is connected to the die-casting plate 4. A mold frame 5 is installed at the top, and a groove with the same size as the top plate 8 is opened on the mold frame 5 to facilitate the storage of the top plate 8. Connecting rods 6 are symmetrically connected to the mold frame 5, and connecting plates 7 are connected between two connecting rods 6 on the same side. The top plate 8 is connected between the tops of the two connecting plates 7 to eject the die-cast sheet. A spring 9 is connected between each connecting rod 6 and the mold frame 5. Mounting plates 10 are symmetrically installed on the mounting frame 2, and a first bidirectional lead screw 11 is rotatably connected between the two mounting plates 10. A first guide rod 12 is connected between the two bases 10. A pressing frame 13 is symmetrically threaded onto the first bidirectional lead screw 11. The two pressing frames 13 slide with the first guide rod 12 to press the sheet metal. The inner surfaces of the two pressing frames 13 are beveled to facilitate pressing the sheet metal. Connecting blocks 14 are symmetrically distributed on the base 1. A second guide rod 15 is connected to the two rear connecting blocks 14. A second bidirectional lead screw 16 is rotatably connected to the two front connecting blocks 14, allowing the two limiting plates 17 to move synchronously. The second bidirectional lead screw 16... The symmetrical threaded connection has a limiting plate 17, which can limit the plate. The limiting plate 17 is slidably engaged with the second guide rod 15. A motor 18 is installed on the base 1. A first bevel gear 19 is connected to the output shaft of the motor 18. A second bevel gear 20 is connected to the second bidirectional lead screw 16. The first bevel gear 19 and the second bevel gear 20 mesh with each other. The rotating handle 21 passes through the mounting plate 10 on the rear side and is connected to the first bidirectional lead screw 11, making it easy to rotate the first bidirectional lead screw 11. Protective pads 22 are connected to the inner sides of the two limiting plates 17 to protect the plate.

[0024] When die casting of sheet metal is required, the operator first places the sheet metal on the mold frame 5. After placement, the motor 18 is started. The output shaft of the motor 18 drives the first bevel gear 19 to rotate, which in turn drives the second bevel gear 20 to rotate. The second bevel gear 20 drives the second bidirectional lead screw 16 to rotate, causing the limiting plate 17 and the protective pad 22 to move inward along the second guide rod 15 simultaneously. When the two limiting plates 17 contact the sheet metal and complete the limiting, the motor 18 is turned off. Then, the hydraulic rod 3 is started. The telescopic end of the hydraulic rod 3 drives the die casting plate 4 to move downward until the die casting plate 4 reaches the designated position and the sheet metal is die cast. During the die casting process, the sheet metal will squeeze the top plate 8, causing the top plate 8 to move downward along the connecting rod 6, thereby compressing the four springs 9. After die casting, the hydraulic rod 3 is retracted, causing the die casting plate 4 to reset. After completion, the hydraulic rod 3 is closed. As the die casting plate 4 moves upward, as the plate no longer presses against the top plate 8, the four springs 9 push the top plate 8 upward along the connecting rod 6, thereby lifting the die-cast plate to achieve demolding. If the plate is too heavy and the top plate 8 cannot lift it, the operator can rotate the rotary handle. Rotating the handle drives the first bidirectional lead screw 11 to rotate, causing the extrusion frame 13 to move inward along the first guide rod 12. During this process, the inclined surface on the extrusion frame 13 can lift the die-cast plate to achieve demolding. After the die-cast plate is lifted, stop rotating the rotary handle, and then the operator can remove the die-cast plate, completing the entire plate die casting process.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
