Description

Technical Field

[0001] This utility model relates to the field of casting equipment technology, specifically to a manganese silicon alloy powder smelting and casting equipment. Background Technology

[0002] Manganese silicon alloy, as an important ferroalloy material, is widely used in steelmaking as a deoxidizer and alloying additive, and its product quality directly affects the performance of steel. Casting is one of the key steps in the smelting process of manganese silicon alloy, and the rationality of the casting equipment design has a significant impact on the final product's molding quality, production efficiency, and ease of operation.

[0003] Traditional manganese silicon alloy powder smelting and casting equipment typically uses fixed molds for casting, which has the following problems: First, demolding is difficult: After casting, the alloy block is prone to sticking to the mold. Especially when the alloy composition is complex or the cooling shrinkage is uneven, the demolding process often requires manual knocking or the use of external tools, which is not only labor-intensive and inefficient, but also easy to damage the mold or cause damage to the surface of the casting, affecting the product qualification rate. Secondly, the cooling efficiency is low and uneven: after casting, manganese silicon alloys require rapid cooling to stabilize the microstructure and improve efficiency. Traditional molds mostly use natural cooling or external spray cooling, which is slow and makes it difficult to ensure uniform cooling of the castings in each mold slot. This can easily lead to thermal stress, cracks, or microstructural defects inside the castings, affecting the consistency of the product's mechanical properties. Third, the level of automation is low: processes such as demolding and cooling rely heavily on manual operation, making it difficult to achieve continuous and automated production, which restricts the expansion of production scale and the steady improvement of product quality. Fourth, limited functionality: Existing equipment typically focuses on the casting process itself, lacking designs that integrate demolding and efficient cooling functions, resulting in low equipment utilization and a large footprint. In view of this, the present invention proposes a manganese silicon alloy powder smelting and casting device. Utility Model Content

[0004] This invention proposes a manganese-silicon alloy powder smelting and casting device, which solves the problem of poor efficiency of manual demolding in the prior art.

[0005] The technical solution of this utility model is as follows: A manganese silicon alloy powder smelting and casting device includes a workbench, a casting mold is fixedly connected to the top of the workbench, the top of the casting mold has a plurality of mold slots arranged in an array, an installation box is fixedly connected to the bottom of the workbench, a demolding mechanism is provided inside the installation box, the demolding mechanism includes a top plate slidably connected to the inside of the installation box, a plurality of push rods corresponding one-to-one with the mold slots are fixedly connected to the top of the top plate, the plurality of push rods pass through the corresponding mold slots and are slidably connected to the bottom wall of the mold slots, a sliding groove is provided at the bottom of the top plate, and sliders are slidably connected to both ends of the inner side of the sliding groove, and an operating component for driving the top plate to slide in the vertical direction is provided inside the installation box.

[0006] Preferably, the bottom wall of each of the mold slots is provided with a top material groove, and the top rods slide in cooperation with the corresponding top material grooves.

[0007] Preferably, the operating component includes two rotating rods symmetrically distributed along the center of the mounting box. The bottom ends of the two rotating rods are rotatably connected to the bottom wall of the mounting box via pins, and the top ends of the two rotating rods are respectively hinged to two sliders.

[0008] Preferably, the operating component further includes two worm gears, which are coaxially and fixedly connected to two rotating rods respectively. A motor is fixedly installed at the bottom of the mounting box, and a worm is fixedly connected to the output shaft of the motor. Both worm gears mesh with the worm.

[0009] Preferably, the inner side of the casting mold is provided with a cooling plate groove, and the inlet end of the cooling plate groove is provided with a water supply mechanism for introducing cooling water into the cooling plate groove.

[0010] Preferably, the water supply mechanism includes a cold water storage tank fixedly connected to the outside of the installation box, a circulating water pump fixedly installed on the outer wall of the installation box, a first liquid guide pipe fixedly connected to the inlet end of the circulating water pump, the first liquid guide pipe being connected to the outlet end of the cooling plate trough, and a second liquid guide pipe fixedly connected to the outlet end of the circulating water pump, the outlet end of the second liquid guide pipe being connected to the inlet end of the cooling plate trough.

[0011] The working principle and beneficial effects of this utility model are as follows: 1. By driving the worm gear mechanism with a motor, the top plate and the ejector rod rise synchronously, which can eject all the molded alloy blocks in the mold slots at the same time. This completely changes the traditional demolding method that relies on manual hammering, greatly improves demolding efficiency, and meets the needs of continuous and automated production.

[0012] 2. Mechanical demolding replaces high-intensity manual labor, while avoiding the safety hazards of operators working near high-temperature molds, improving the working environment, and reducing labor costs and operational risks.

[0013] 3. A closed-loop cooling circulation system (cold water storage tank → water pump → cooling tray → return storage tank) is adopted, which allows the cooling water to be reused, saving water resources and reducing production costs. At the same time, the system can maintain a more stable cooling temperature, which is beneficial to process control. Attached Figure Description

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0018] like Figures 1-5As shown, this embodiment proposes a manganese silicon alloy powder smelting and casting device, including a workbench 1, a casting mold 2 fixedly connected to the top of the workbench 1, a plurality of mold grooves 3 arranged in an array on the top of the casting mold 2, an installation box 4 fixedly connected to the bottom of the workbench 1, a demolding mechanism 5 provided inside the installation box 4, the demolding mechanism 5 including a top plate 51 slidably connected to the inside of the installation box 4, a plurality of push rods 52 corresponding one-to-one with the mold grooves 3 fixedly connected to the top of the top plate 51, the plurality of push rods 52 passing through the corresponding mold grooves 3 and slidably connected to the bottom wall of the mold grooves 3, the bottom wall of the plurality of mold grooves 3 is provided with a material ejector groove 21, the plurality of push rods 52 are slidably engaged with the corresponding material ejector groove 21, a sliding groove 54 is provided at the bottom of the top plate 51, and sliders 53 are slidably connected to both ends of the inner side of the sliding groove 54, and an operating component 55 for driving the top plate 51 to slide in the vertical direction is provided inside the installation box 4.

[0019] During casting, molten manganese-silicon alloy liquid is poured into multiple arrayed mold grooves 3 on the top of the casting mold 2. After the manganese-silicon alloy cools and solidifies, the top plate 51 is driven upward by the operating component 55, so that all the ejector rods 52 pass through the ejector groove 21 at the bottom of the mold groove 3, and the molded alloy block is ejected from the mold groove 3, achieving rapid demolding. This design can quickly eject all the molded alloy blocks inside the mold groove 3 simultaneously, greatly improving demolding efficiency.

[0020] Furthermore, the operating component 55 includes two rotating rods 551 symmetrically distributed along the center of the mounting box 4. The bottom ends of the two rotating rods 551 are rotatably connected to the bottom wall of the mounting box 4 via pins. The top ends of the two rotating rods 551 are respectively hinged to two sliders 53. Worm gears 552 are coaxially fixedly connected to both rotating rods 551. A motor 553 is fixedly installed at the bottom of the mounting box 4. A worm gear 554 is fixedly connected to the output shaft of the motor 553. Both worm gears 552 mesh with the worm gear 554.

[0021] During demolding, the worm gear 554 is driven to rotate by the motor 553. Since the worm gear 554 meshes with two worm wheels 552, it can drive the two rotating rods 551 to rotate synchronously inward or outward, so that the top of the rotating rod 551 is hinged to the slider 53, pushing the slider 53 to slide in the groove 54 at the bottom of the top plate 51. This converts the movement of the slider 53 into the vertical lifting and lowering movement of the top plate 51, which drives all the ejector rods 52 to rise synchronously. The ejector rods 52 pass through the ejector groove 21 at the bottom of the mold groove 3, pushing the molded alloy block out of the mold groove 3, thus achieving demolding. This design achieves synchronous demolding of multiple mold grooves 3 through worm gear transmission and ejector rod array design, which significantly improves production efficiency. The motor 553 drive replaces manual operation, reduces labor intensity, and avoids safety hazards in high-temperature environments.

[0022] Furthermore, a cooling tray 22 is provided on the inner side of the casting mold 2. A water supply mechanism 6 for introducing cooling water into the cooling tray 22 is provided at the inlet end of the cooling tray 22. The water supply mechanism 6 includes a cold water storage tank 61 fixedly connected to the outside of the mounting box 4. A circulating water pump 62 is fixedly installed on the outer wall of the mounting box 4. A first liquid guide pipe 63 is fixedly connected to the inlet end of the circulating water pump 62. The first liquid guide pipe 63 is connected to the outlet end of the cooling tray 22. A second liquid guide pipe 64 is fixedly connected to the outlet end of the circulating water pump 62. The outlet end of the second liquid guide pipe 64 is connected to the inlet end of the cooling tray 22.

[0023] After casting, the molten manganese-silicon alloy liquid in mold trough 3 needs to be cooled. The specific implementation process is as follows: By starting the circulating water pump 62, cooling water in the cold water storage tank 61 is pumped into the cooling tray 22 inside the casting mold 2 through the second liquid guide pipe 64. The water flows in the cooling tray 22, accelerating the solidification of the alloy. The cooled water returns to the circulating water pump 62 through the first liquid guide pipe 63, forming a closed-loop cooling cycle to ensure cooling uniformity and efficiency. The cooling tray 22 is distributed around the mold slot 3. In conjunction with the circulating water system, it ensures uniform cooling of the alloy block, reduces internal stress cracks, saves water resources, maintains stable cooling temperature, and improves product consistency.

[0024] The above are merely preferred embodiments of the present utility model and are 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 shall be included within the protection scope of the present utility model.
