[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model embodiment provides a melting furnace for ferrous metal casting, such as Figure 1-3As shown, a melting furnace for ferrous metal casting includes: a support frame 1; a heating furnace 2, which is rotatably mounted on the support frame 1; a rotary motor 3, which is fixedly mounted on the support frame 1, and the output shaft of the rotary motor 3 is fixedly connected to the heating furnace 2; a storage cylinder 4, which is fixedly mounted on the heating furnace 2; a furnace cover 5, which is rotatably mounted on the heating furnace 2 and is used to close the opening of the storage cylinder 4; a pouring spout 6, which is opened on the storage cylinder 4; a movable groove 7, which is opened on the furnace cover 5; a movable sealing plate 8, which is slidably mounted in the movable groove 7 and closes the pouring spout 6; and an opening adjustment mechanism, which is disposed on the furnace cover 5 and is used to adjust the movable sealing plate 8 to control the opening and closing of the pouring spout 6.

[0021] In this embodiment, ferrous metal material is placed in the storage cylinder 4, and the furnace lid 5 is closed. The metal material in the storage cylinder 4 is heated and melted by the heating furnace 2. After the metal material melts, the rotary motor 3 is started, which drives the heating furnace 2 to rotate, causing the pouring spout 6 of the storage cylinder 4 to tilt downwards. At the same time, the movable sealing plate 8 is adjusted by the opening adjustment mechanism to open the pouring spout 6, allowing the molten metal to be poured from the pouring spout 6 into the casting mold for cooling and solidification. The rotary motor 3 is model YE3-250M-4. This patent, by setting up the pouring spout 6, the movable sealing plate 8, and the opening adjustment mechanism, eliminates the need to fully open the furnace lid 5 when pouring molten metal. Simply adjusting the movable sealing plate 8 through the opening adjustment mechanism opens the pouring spout 6, avoiding the laborious pouring problem caused by the heavy furnace lid 5 and facilitating the use of the melting furnace. A movable sealing plate 8 is used to close the pouring opening 6. During the heating process, the movable sealing plate 8 can better seal the placing cylinder 4, preventing heat loss and molten metal splashing, thus improving the safety of the melting furnace. The rotary motor 3 drives the heating furnace 2 to rotate, realizing the tilting of the pouring opening. The opening adjustment mechanism controls the opening and closing of the pouring opening 6. The overall structure is reasonably designed, easy to operate, and improves the efficiency of ferrous metal casting.

[0022] In a further preferred embodiment of this utility model, the opening adjustment mechanism includes a drive block 9, a slide groove 10, a fixing block 11, a drive screw 12, and a drive mechanism. The drive block 9 is fixedly installed on the movable sealing plate 8 and slides through the furnace cover 5. The slide groove 10 is opened on the furnace cover 5 and is slidably connected to the drive block 9. The fixing block 11 is fixedly installed on the furnace cover 5 and is disposed on both sides of the slide groove 10. The drive screw 12 is rotatably installed between the fixing blocks 11. The drive mechanism is disposed on the furnace cover 5 and is used to drive the drive screw 12 to rotate.

[0023] In this embodiment, when it is necessary to adjust the opening and closing of the pouring spout 6, the drive mechanism is activated, which drives the drive screw 12 to rotate. Since the drive block 9 is fixed to the movable sealing plate 8 and slides through the furnace cover 5, and is also slidably connected to the slide groove 10, when the drive screw 12 rotates, the drive block 9 moves along the drive screw 12, thereby causing the movable sealing plate 8 to slide within the movable groove 7, thus controlling the opening and closing of the pouring spout 6. Compared to a simple opening and closing method, this opening adjustment mechanism, through the rotation of the drive screw 12 and the connection between the drive block 9 and the movable sealing plate 8, can more precisely control the sliding distance of the movable sealing plate 8, thereby precisely adjusting the opening and closing degree of the pouring spout 6 to meet the needs of different pouring volumes. The drive mechanism is located on the furnace cover 5, allowing operators to easily control the drive mechanism to drive the drive screw 12 to rotate, thereby adjusting the opening and closing of the pouring spout 6 without the need for manual and laborious adjustment of the movable sealing plate 8, thus improving operational convenience. The fixing block 11 is fixed on the furnace cover 5 and located on both sides of the slide groove 10, providing stable support for the drive screw 12, making the drive screw 12 more stable during rotation, reducing the problem of inaccurate movement of the movable sealing plate 8 caused by the shaking of the drive screw 12, and enhancing the structural stability of the entire opening adjustment mechanism.

[0024] In a further preferred embodiment of this utility model, the driving mechanism includes a fixed sprocket 13, a mounting bracket 14, a drive motor 15, a drive sprocket 16, and a transmission chain 17. The fixed sprocket 13 is fixedly mounted on the drive screw 12, the mounting bracket 14 is fixedly mounted on the fixing block 11 and is fixedly connected to the furnace cover 5, the drive motor 15 is fixedly mounted on the mounting bracket 14, the drive sprocket 16 is fixedly mounted on the output shaft of the drive motor 15, and the transmission chain 17 is sleeved between the fixed sprocket 13 and the drive sprocket 16.

[0025] In this embodiment, when it is necessary to adjust the opening and closing of the pouring spout 6, the drive motor 15 is started. The output shaft of the drive motor 15 drives the drive sprocket 16 to rotate. The model of the drive motor is MHMD042G1A. Since the transmission chain 17 is sleeved between the fixed sprocket 13 and the drive sprocket 16, the rotation of the drive sprocket 16 will drive the fixed sprocket 13 to rotate through the transmission chain 17. The fixed sprocket 13 is fixed on the drive screw 12, thereby driving the drive screw 12 to rotate. When the drive screw 12 rotates, the drive block 9 will move along the drive screw 12, thereby driving the movable sealing plate 8 to slide in the movable groove 7, realizing the control of the opening and closing of the pouring spout 6. Through the cooperation of the fixed sprocket 13, the drive sprocket 16 and the transmission chain 17, the power of the drive motor 15 is stably transmitted to the drive screw 12. This chain drive method can withstand a large load and has an accurate transmission ratio, ensuring the stability of the rotation of the drive screw 12, thereby making the movement of the movable sealing plate 8 smoother and improving the accuracy of the opening and closing control of the pouring spout 6. Mounting bracket 14 is fixed to fixing block 11 and fixedly connected to furnace cover 5, providing a stable mounting base for drive motor 15, and also facilitating maintenance and repair of the drive mechanism. The drive motor 15 provides an automated power source for the opening and closing control of tilting port 6. Operators only need to start drive motor 15 to adjust the opening and closing of tilting port 6, eliminating the need for manual operation, thus improving the automation level of the melting furnace and reducing labor intensity.

[0026] In a further preferred embodiment of the present invention, the mounting bracket 14 is composed of a horizontal plate and a support leg. The horizontal plate is fixedly mounted on the fixing block 11. The horizontal plate has a slot for the transmission chain 17 to pass through. The support leg is fixedly mounted on the bottom of the horizontal plate and is fixedly connected to the top of the furnace cover 5.

[0027] In this embodiment, the slots on the horizontal plate provide a specific running channel for the transmission chain 17, preventing interference between the transmission chain 17 and other components during operation. This ensures the stability and reliability of the transmission chain 17's operation, allowing the power of the drive motor 15 to be accurately transmitted to the drive screw 12, and improving the precision of the opening and closing control of the tilting port 6. The support legs fix the horizontal plate to the top of the furnace cover 5, forming a stable support structure. This structure can withstand the forces and vibrations generated by components such as the drive motor 15 and the transmission chain 17, enhancing the structural stability of the entire mounting frame 14, reducing component loosening and damage caused by vibration, and extending the service life of the equipment.

[0028] In a further preferred embodiment of the present invention, a limiting groove 18 is provided in the movable groove 7, and a protrusion is fixedly installed on the movable sealing plate 8, the protrusion being slidably embedded in the limiting groove 18.

[0029] In this embodiment, the cooperation between the limiting groove 18 and the protrusion provides precise guidance for the sliding of the movable sealing plate 8, preventing the movable sealing plate 8 from deviating or wobbling during sliding, enabling the movable sealing plate 8 to move more stably and improving the accuracy of the opening and closing control of the pouring spout 6. The protrusion slides into the limiting groove 18, increasing the connection strength between the movable sealing plate 8 and the movable groove 7, reducing the possibility of the movable sealing plate 8 loosening or falling off during use, and enhancing the structural reliability of the entire opening adjustment mechanism. The limiting groove 18 restricts the sliding of the protrusion, making the sliding of the movable sealing plate 8 smoother, reducing friction and wear between the movable sealing plate 8 and the movable groove 7, and extending the service life of the movable sealing plate 8 and the movable groove 7.

[0030] In a further preferred embodiment of the present invention, a guide rod 19 is fixedly installed in the slide groove 10, and the guide rod 19 slides through the drive block 9.

[0031] In this embodiment, the guide rod 19 slides through the drive block 9, providing precise guidance for the movement of the drive block 9. This prevents the drive block 9 from deviating or wobbling when moving within the slide groove 10, allowing the drive block 9 to move more stably. This, in turn, improves the stability of the movable sealing plate 8 and ensures the accuracy of the opening and closing control of the pouring opening 6. The presence of the guide rod 19 increases the connection strength between the drive block 9 and the slide groove 10, reducing the possibility of the drive block 9 loosening or falling off during use, and enhancing the structural reliability of the entire opening adjustment mechanism. The guide rod 19 also restricts the sliding of the drive block 9, making its sliding smoother, reducing friction and wear between the drive block 9 and the slide groove 10, and extending the service life of both the drive block 9 and the slide groove 10.

[0032] In a further preferred embodiment of this utility model, an adjusting motor 20 is fixedly installed on the heating furnace 2, the output shaft of the adjusting motor 20 is fixedly connected to the furnace cover 5, a support block 21 is fixedly installed at the bottom of the furnace cover 5, the support block 21 is in sliding contact with the top of the heating furnace 2, and the support block 21 is located at the rotational connection point between the furnace cover 5 and the heating furnace 2.

[0033] In this embodiment, when it is necessary to open or close the furnace cover 5, the regulating motor 20 is started. The output shaft of the regulating motor 20 drives the furnace cover 5 to rotate. The regulating motor is model YE3-100L. Since the support block 21 slides in contact with the top of the heating furnace 2, it provides stable support for the furnace cover 5 during rotation, reducing swaying and deformation, allowing the furnace cover 5 to open or close smoothly. Simultaneously, when it is necessary to adjust the angle of the furnace cover 5 to coordinate with the opening adjustment mechanism for controlling the opening and closing of the tilting spout 6, the regulating motor 20 can precisely control the rotation angle of the furnace cover 5, meeting different usage requirements. The regulating motor 20 provides an automated power source for the opening and closing of the furnace cover 5. Operators only need to start the regulating motor 20 to open or close the furnace cover 5, eliminating the need for manual operation, thus improving the automation level of the melting furnace and reducing labor intensity. The support block 21 slides in contact with the top of the heating furnace 2, playing a supporting and guiding role during the rotation of the furnace cover 5. This reduces the shaking and deformation of the furnace cover 5 during rotation, making the rotation of the furnace cover 5 more stable, improving the sealing performance between the furnace cover 5 and the heating furnace 2, and reducing heat loss.

[0034] In summary, compared with related technologies, the coordinated action of the opening adjustment mechanism, mounting bracket, limiting groove and protrusion, guide rod and drive block ensures stable sliding of the movable sealing plate within the movable groove, achieving precise control of the opening and closing of the pouring spout and improving the accuracy of the pouring volume. The adjustment motor enables automated opening and closing of the furnace lid, reducing labor intensity and increasing the automation level of the melting furnace. Simultaneously, the addition of the support block enhances the stability of the furnace lid rotation and reduces heat loss. The design of the mounting bracket, limiting groove, guide rod, and other structures optimizes the overall structural layout of the melting furnace, improving space utilization. Furthermore, these structures strengthen the connection between various components of the melting furnace, reducing the possibility of loosening and detachment, and extending the service life of the equipment.
