Description

Technical Field

[0001] This utility model relates to the field of ferroalloy block casting, and in particular to an adjustable combined demolding mold and a production line for casting ferroalloy blocks. Background Technology

[0002] In the field of ferroalloy block processing, the traditional method of casting ferroalloy blocks (such as ferrosilicon, ferromanganese, metallic silicon, high-carbon ferrochrome, etc.) involves first casting molten ferroalloy into large blocks, which are then manually broken down with hammers or mechanically. This method results in a large workforce, inconsistent block sizes, excessive powder, significant waste, and substantial safety hazards. With technological innovation, this invention directly casts molten ferroalloy into several uniformly sized blocks using a mold, and then automatically demolds them using a push rod.

[0003] Chinese patent publication number CN112846154B, entitled "A High-Temperature Casting Continuous Demolding Combined Equipment," describes a process where an iron alloy block is formed inside a mold body before demolding. However, the guide plate is fixedly connected to the frame, making adaptive adjustment difficult. This prolonged extreme compression of the spring causes its tension to gradually decrease, accelerating spring replacement cycles and increasing production costs. Utility Model Content

[0004] To address the above problems, this utility model provides an adjustable combined demolding mold and a production line for casting iron alloy blocks.

[0005] The technical solution of this utility model is: an adjustable combined demolding mold, including a frame, a track guide plate, a transmission chain, and several combined mold devices. The trajectory guide plate is connected to the frame by jacks. Several combined mold equipment are sequentially arranged on the transmission chain, and the trajectory guide plate is used to contact the combined mold equipment.

[0006] The combined mold equipment includes a mold body, an ejector pin, an ejector pin positioning plate, an ejector pin limiting plate, a spring pull rod, a spring, and a roller. The mold body is provided with several mold cavities and several through holes. The mold cavities are used to form iron alloy blocks. The mold cavities and through holes correspond one-to-one and are connected. The through holes are provided with push rods that extend into the mold cavities and push the iron alloy blocks. The top rod positioning plate and the top rod limiting plate are arranged side by side and have corresponding through holes. The top rod positioning plate and the top rod limiting plate are connected by bolts. The spring rod is fixedly connected to the mold body, and one end of the spring rod that passes through the through hole of the top rod positioning plate and the top rod limiting plate is connected to an anti-detachment pin or is connected to a nut through a thread. The spring is sleeved on the spring rod and is located between the top rod positioning plate and the mold body; The top rod positioning plate is provided with an inverted convex hole, and the T-shaped rod head of the top rod is located in the inverted convex hole; The top rod limiting plate is provided with a pair of symmetrical supports, and the roller is movably connected between the pair of supports through a roller shaft. The roller is used to contact the bottom of the track guide plate.

[0007] The spring rod is integrally cast with the mold body. Alternatively, the spring rod may be welded to the mold body; Alternatively, the bottom of the mold body may be provided with a T-shaped groove, and the end of the spring rod may be T-shaped and connected to the T-shaped groove.

[0008] The mold body includes an upper mold body and a lower mold body. The mold cavity is located in the upper mold body, and the perforation is located in the lower mold body. The upper mold body is detachably connected to the lower mold body.

[0009] The top rod is a split type. Alternatively, the end of the push rod that extends into the mold cavity may be provided with a high-temperature resistant coating.

[0010] A production line for casting ferroalloy blocks, including adjustable modular demolding molds. It also includes ladles and guide channels. The ladle pours molten iron alloy into the combined mold equipment on the transmission chain through the guide flow channel. When the combined mold equipment passes the track guide plate, the formed iron alloy block is demolded.

[0011] It also includes a conveyor line, a cooling water tank, and a packaging line, which demolds the formed ferroalloy blocks onto the conveyor line for transport. The ferroalloy blocks on the conveyor line are cooled by a cooling water tank. After cooling, the conveyor line continues to transport the ferroalloy blocks to the packaging line for packaging.

[0012] The cooling water pool is equipped with a cover, which is connected to a water vapor removal machine via pipes.

[0013] A cooling tower is connected to the cooling water pool.

[0014] It also includes a flow interruption device, which comprises a ferroalloy water tank and an openable / closable flow channel. The guide flow channel is provided with an openable and closable flow channel, which is movably connected to the guide flow channel. The openable and closable flow channel is used to open and close the guide flow channel, and the ferroalloy water tank is located below the openable and closable flow channel.

[0015] It also includes a buffer pool, which is located on the guide flow channel and is used to control the flow rate of the ferroalloy water.

[0016] In operation, this invention uses a jack between the frame and the guide plate to provide flexible adjustment. This avoids prolonged compression of the springs in the mold assembly during ejection, thus preventing spring tension decay, reducing spring replacement cycles, increasing service life, and lowering production costs.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or a welded connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] This utility model is as follows Figure 1-13 As shown, the adjustable combined demolding mold includes a frame 1, a track guide plate 2, a transmission chain 4, and several combined mold devices 3. The trajectory guide plate 2 is connected to the bottom of the frame 1 by jacks 5. Several combined mold equipment 3 are sequentially arranged on the transmission chain 4, and the trajectory guide plate 2 is used to contact the combined mold equipment 3.

[0023] In operation, this invention uses a jack between the frame and the guide plate to provide flexible adjustment. This avoids prolonged extreme compression of the springs in the combined mold during ejection, thus preventing spring tension decay, reducing spring replacement cycles, increasing service life, and lowering production costs.

[0024] The combined mold equipment includes a mold body 31, an ejector pin, an ejector pin positioning plate 33, an ejector pin limiting plate 34, a spring pull rod 35, a spring 36, and a roller 38. The mold body 31 is provided with a plurality of mold cavities 311 and a plurality of through holes 312. The mold cavity 311 is used to form iron alloy blocks. The mold cavity 311 and the through holes 312 are in one-to-one correspondence and connected. The through holes are provided with push rods 32 for extending into the mold cavity and pushing the iron alloy blocks. The top rod positioning plate 33 and the top rod limiting plate 34 are arranged side by side and have corresponding through holes. The top rod positioning plate and the top rod limiting plate are connected by bolts. The spring rod 35 is fixedly connected to the mold body 31. One end of the spring rod 35 that passes through the through hole of the top rod positioning plate and the top rod limiting plate is connected to the anti-detachment pin 39 or is connected to the nut through the thread. The spring 36 is sleeved on the spring rod 35 and is located between the push rod positioning plate and the mold body; The top rod positioning plate 33 is provided with an inverted convex hole, and the T-shaped rod head of the top rod is located in the inverted convex hole; The top rod limiting plate 34 is provided with a pair of symmetrical supports 37, and the roller 38 is movably connected between the pair of supports 37 through the roller shaft. The roller 38 is used to contact the bottom of the track guide plate 2.

[0025] Because the combined mold equipment is equipped with several ejector pins, they can be fixed by ejector pin positioning plates and ejector pin limiting plates. That is, all ejector pins can be pushed into and out of the mold cavity simultaneously under the drive of the ejector pin limiting plates, which is convenient for operation. Several corresponding through holes are provided on the ejector pin limiting plate and ejector pin positioning plate to facilitate the insertion of the spring rod. Each spring rod is equipped with a return spring. One end of the spring contacts the mold body and the other end contacts the ejector pin positioning plate. In the initial state, a certain tension is maintained so that the ejector pin closes the mold cavity for the molding of the iron alloy block 22.

[0026] The roller is designed so that the guide plate can act directly on it, pressing down while rolling, reducing frictional resistance, ensuring reliable movement, and thus controlling the action of the push rod.

[0027] The spring rod 35 is integrally cast with the mold body 31. Alternatively, the spring rod 35 may be welded to the mold body 31; Alternatively, the bottom of the mold body may be provided with a T-shaped groove 315, and the end of the spring rod 35 is T-shaped and connected to the T-shaped groove.

[0028] Depending on the processing requirements, the spring tie rod and the mold body can be integrally cast or welded together, which facilitates the formation of a whole and improves strength.

[0029] Alternatively, a T-shaped structure can be used to facilitate the connection between the spring rod and the mold body, making assembly and disassembly easier.

[0030] The mold body 31 includes an upper mold body 313 and a lower mold body 314. The mold cavity 311 is located inside the upper mold body 313, and the through hole 312 is located inside the lower mold body 314. The upper mold body is detachably connected to the lower mold body.

[0031] By combining an upper mold body and a lower mold body, if the mold body is damaged, only one part needs to be replaced, instead of replacing the entire mold. This saves costs and time, conserves mold materials, and improves economic efficiency.

[0032] The mold body can be made of T1 forged copper, T2 forged copper, T3 forged copper, T4 forged copper, TU1 oxygen-free copper, TU2 oxygen-free copper, or copper alloy forging materials. It can also be made of non-metallic high-temperature resistant materials, non-metallic high-temperature resistant composite materials, etc.

[0033] The top rod is a split type. Alternatively, the end of the push rod 32 that extends into the mold cavity may be provided with a high-temperature resistant coating.

[0034] In applications, high-temperature resistant coatings such as tungsten, molybdenum, zirconium oxide, silicon carbide, and silicon nitride are used to improve the service life of the push rod.

[0035] The ejector rod 32 includes rod body one and rod body two, with rod body one detachably connected to rod body two. Designing the ejector rod as a separate unit facilitates replacement should the rod body two (facing the mold cavity) break, thus saving costs. Rod body one and rod body two are connected by threads for easy assembly and disassembly.

[0036] The transmission chain is circular, and the combined mold equipment is connected to the transmission chain. First, the casting is performed. Before passing the adjustable track guide plate of the jack, the iron alloy block solidifies in the mold cavity and cannot be automatically demolded. When the transmission chain drives the combined mold equipment to move, the adjustable track guide plate of the jack gradually compresses the rollers of several combined mold equipment downwards, forcing the ejector rods inside the combined mold equipment to penetrate deeper into the mold cavity, thus ejecting the iron alloy block out of the mold cavity. When the combined mold equipment moves to the bottom of the adjustable track guide plate of the jack, the ejector rod extends to its maximum distance, that is, the iron alloy block is completely separated from the mold cavity. At this time, the lower scraper 7 fixed to the lower frame 6 scrapes off the protruding iron alloy block, so that the iron alloy block is completely demolded. When the transmission chain continues to drive, the rollers gradually get rid of the pressure of the adjustable track guide plate of the jack, and the ejector rods gradually return to the initial position under the tension of the spring, so that the mold body forms a complete mold cavity again. The transmission chain operates in a cycle. After the combined mold equipment pours molten iron alloy again, the combined mold equipment repeats the cycle to complete the automatic demolding process. This utility model realizes the automatic packaging of products from pouring iron alloy blocks to product packaging, forming a production system where products do not touch the ground.

[0037] like Figure 7-9 As shown, the production line for casting ferroalloy blocks includes adjustable combination demolding molds. It also includes a ladle 8, a guide channel 9, a conveyor line 10, a cooling water tank 11, and a packaging line 12. The ladle 8 pours molten iron alloy into the combined mold equipment 3 on the transmission chain 4 through the guide flow channel 9. When the combined mold equipment passes the track guide plate 2, the formed iron alloy block is demolded onto the conveyor line 10 for conveying. The ferroalloy blocks on the conveyor line 10 are cooled by the cooling water tank 11. After cooling, the conveyor line 10 continues to transport the ferroalloy blocks to the packaging line 12 for packaging.

[0038] Cast iron alloy block production lines can be divided into single-row (i.e.) Figure 10 ) or double row (i.e. Figure 9 , 11 12), the casting method is divided into casting using a workshop overhead crane iron alloy water ladle (i.e., casting ladle) or casting using a tilting mechanism 27 tilting iron alloy water ladle (i.e., casting ladle), where the tilting mechanism is a conventional structure. Similarly, such as Figure 12 As shown, after smelting ferroalloys in the submerged arc furnace 28, the ferroalloy blocks are poured through a flow channel, a skimmer 20, a slag pool 21, a flow interruption device, a ferroalloy water pool, and a buffer pool. In application, after smelting ferroalloys in the submerged arc furnace 28, a ferroalloy water ladle is connected, and then the ferroalloy water ladle is transferred for subsequent pouring operations.

[0039] In application, the production line also includes conventional equipment such as drying device 24, high-temperature resistant medium spraying equipment 25, and high-temperature resistant medium spraying tank 26.

[0040] This utility model is a complete production line equipment that realizes automated casting of ferroalloy blocks, from casting ferroalloy molten metal to automatic demolding and automatic packaging of ferroalloy blocks.

[0041] When the molten ferroalloy flows into the mold body, it is instantly and evenly scraped into the mold cavity by the upper scraper 23. The combined mold equipment containing the molten ferroalloy solidifies through natural cooling or is cooled rapidly by spraying circulating water after the ferroalloy block has solidified. When the combined mold equipment is driven by the transmission chain to the demolding station, the combined mold equipment containing the ferroalloy block is squeezed by the adjustable track guide plate of the jack, and the ejector rod pushes out the ferroalloy block in the mold to achieve automatic demolding of the ferroalloy block.

[0042] After demolding, the ferroalloy blocks are cooled in a cooling water tank. After cooling, the conveyor line continues to transport the ferroalloy blocks to the packaging line for packaging. Figure 9 , Figure 11 and Figure 12 At point M is Figure 1 The view in the middle. Figure 11 , 12 The middle arrow indicates the direction of movement of the ferroalloy block.

[0043] The cooling water pool is equipped with a cover 13, which is connected to a water vapor removal machine 15 (or a steam removal machine, which is a conventional device) via a pipe 14.

[0044] Installing a moisture removal machine facilitates the removal of moisture and improves the quality of the processing environment.

[0045] Cooling tower 16 is connected to the cooling water pool.

[0046] Setting up a cooling tower to lower the water temperature in the cooling water tank can better cool the ferroalloy block.

[0047] It also includes a flow interruption device, which comprises an iron alloy water tank 17 and an openable / closable flow channel 18. The guide flow channel is provided with an openable and closable flow channel, which is movably connected to the guide flow channel. The openable and closable flow channel is used to open and close the guide flow channel, and the ferroalloy water tank is located below the openable and closable flow channel.

[0048] In the event of equipment failure, the ferroalloy molten metal is directly diverted into the ferroalloy molten metal pool by interrupting the flow, thus preventing the high-temperature ferroalloy molten metal from flowing into the equipment and causing damage.

[0049] It also includes a buffer tank 19, which is connected to the guide flow channel and is used to control the flow rate of the ferroalloy water.

[0050] A buffer tank is set up to control the flow rate of the ferroalloy molten metal and prevent the flow rate from exceeding the capacity of the casting mold.

[0051] Regarding the information disclosed in this case, the following points need to be clarified: (1) The accompanying drawings of the embodiments disclosed in this case only involve the structures involved in the embodiments disclosed in this case. Other structures can refer to the general design. (2) Where there is no conflict, the embodiments and features disclosed in this case can be combined with each other to obtain new embodiments; The above are merely specific embodiments disclosed in this case, but the scope of protection of this disclosure is not limited thereto. The scope of protection disclosed in this case shall be determined by the scope of protection of the claims.
