Description

Technical Field

[0001] This utility model relates to the field of casting equipment technology, and more specifically, to a tilting casting machine for casting metal parts. Background Technology

[0002] In the field of metal casting, the casting machine is the core equipment for achieving precise pouring of molten metal, and its performance directly affects the quality of castings and production efficiency. With industry development, casting machine technology is constantly iterating. For example, the casting machine disclosed in invention application number 201710290535.0, through the coordination of structures such as a sliding platform, a rotating platform, an outreach arm, and a ladle mounting frame, achieves flexible multi-dimensional control of the ladle, giving the equipment advantages such as simple structure, convenient operation, high working efficiency, and good pouring effect, thus meeting production needs to a certain extent.

[0003] However, this type of casting machine still has limitations in practical applications. Its complex multi-platform, multi-joint structure increases manufacturing costs and maintenance difficulty. The ladle's reliance on handwheels for axial and radial rotation makes it difficult to further improve operational efficiency during large-scale, continuous production, and the lack of stability in manual operation can easily lead to fluctuations in casting accuracy. Furthermore, the equipment lacks an effective design to guide the flow path of the molten metal during casting, easily causing turbulence and splashing during pouring, resulting in material waste, affecting casting quality, and posing safety hazards. Moreover, existing casting machines lack reliable safety locking structures when idle or under maintenance, failing to effectively prevent accidental ladle tilting and threatening the safety of operators. Utility Model Content

[0004] The purpose of this invention is to provide a tilting casting machine for metal casting, in order to solve the problem mentioned in the background art that the operation method of the ladle relies on a handwheel to achieve axial rotation and radial swing. When facing large-scale and continuous production, it is difficult to further improve the operation efficiency, and the stability of manual operation is insufficient, which easily leads to fluctuations in casting accuracy.

[0005] To achieve the above objectives, this utility model provides a tilting casting machine for metal casting, including a base, a positioning seat installed on the top of the base, a casting hopper hinged to the top of the positioning seat, and a lower side of the casting hopper connected to the base via a telescopic cylinder. The telescopic cylinder drives the casting hopper to rotate around the positioning seat by telescopic movement, thereby realizing the tilting casting action. A safety lock is installed on the bottom side of the base away from the telescopic cylinder.

[0006] This setup provides stable support via a base, with the positioning seat acting as a hinge point to allow the pouring hopper to rotate. The extension and retraction of the telescopic cylinder drives the pouring hopper to rotate around the positioning seat, achieving tilting pouring. A safety lock is used to lock the pouring hopper during equipment maintenance or when the equipment is idle.

[0007] Preferably, the bottom end of the telescopic cylinder is hinged to the base, and the piston end of the telescopic cylinder is hinged to the casting hopper.

[0008] This feature allows the telescopic cylinder to be hinged at both ends to the base and the pouring hopper, forming a movable connection that smoothly converts the linear motion of the telescopic cylinder into the rotational motion of the pouring hopper.

[0009] Preferably, a guide pipe is installed on one side of the base, and when the pouring hopper is used for pouring, the liquid flows downward through the guide pipe to perform a precise pouring operation.

[0010] This feature involves installing a guide pipe on one side of the base, corresponding to the position of the pouring hopper, to guide the molten metal along a specific path during pouring.

[0011] Preferably, the top of the guide tube is provided with a funnel-shaped opening.

[0012] The funnel opening at the top of the guide tube is widened in a funnel shape to facilitate the collection of molten metal poured from the casting bucket.

[0013] Preferably, the inner wall of the guide tube is provided with a spiral guide groove, the spiral guide groove having a lead of 50-100mm and a depth of 3-5mm, which is used to guide the molten metal to form a rotating flow and reduce turbulence and splashing during pouring.

[0014] This feature involves a spiral guide groove on the inner wall of the guide tube, which guides the molten metal to form a rotating flow through a spiral structure with a specific lead and depth.

[0015] Preferably, the safety lock includes a support column, the bottom end of which is rotatably connected to the base via a pin, and a U-shaped plate is installed at the bottom of the casting hopper near the top of the support column. The top of the support column is locked into the U-shaped plate and secured by a locking bolt.

[0016] The support column for this safety lock is rotatably connected to the base via a pin. When in use, it can be erected to engage with the U-shaped plate at the bottom of the pouring hopper and secured with locking bolts.

[0017] Preferably, fixing plates are welded to both ends of the pin, and the bottom of the fixing plates is welded and fixed to the base.

[0018] This feature involves welding the fixing plates at both ends of the pin to the base, thereby enhancing the stability of the connection between the pin and the base.

[0019] Preferably, a locking hole is provided on one side of the top of the support column, and one end of the locking bolt passes through the U-shaped plate and is threadedly connected to the locking hole.

[0020] This feature allows for a detachable, fixed connection between the locking hole at the top of the support column and the U-shaped plate via a locking bolt threaded connection.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] In this tilting casting machine for metal casting, the design of hinged bottom of the telescopic cylinder to the base and hinged piston end to the casting hopper allows the casting hopper to rotate stably around the positioning seat, achieving tilting casting. Compared to the traditional handwheel drive method, this automated drive structure significantly improves the convenience and stability of operation, effectively increases casting efficiency, and reduces the fluctuation in casting accuracy caused by the instability of manual operation.

[0023] The guide pipe installed on one side of the base plays a crucial role in ensuring casting accuracy and quality control. The funnel-shaped opening at the top of the guide pipe facilitates the smooth flow of molten metal, while the spiral guide grooves on the inner wall effectively guide the molten metal to form a rotating flow. This unique design greatly reduces turbulence and splashing during casting, ensuring that the molten metal flows precisely into the mold, thereby improving the forming quality of the casting and reducing metal waste.

[0024] In terms of equipment safety, the safety lock provides reliable protection for equipment operation and maintenance. The bottom of the support column in the safety lock is rotatably connected to the base via a pin with a fixing plate, ensuring structural stability. When the equipment is idle or under maintenance, the top of the support column can be locked into the U-shaped plate at the bottom of the pouring hopper, and secured by a locking bolt threaded into the locking hole at the top of the support column. This effectively prevents accidental tilting of the pouring hopper and provides strong protection for the personal safety of operators. Attached Figure Description

[0031] 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.

[0032] This utility model provides a tilting casting machine for casting metal parts, such as... Figure 1 , Figure 2 As shown, the system includes a base 1, a positioning seat 11 mounted on top of the base 1, and a pouring hopper 2 hinged to the top of the positioning seat 11. The lower part of one side of the pouring hopper 2 is connected to the base 1 via a telescopic cylinder 3. The telescopic cylinder 3, through its telescopic movement, causes the pouring hopper 2 to rotate around the positioning seat 11, achieving a tilting pouring action. A safety lock 5 is installed on the bottom side of the base 1 away from the telescopic cylinder 3. Support legs 12 are installed at the bottom of the base 1 for support.

[0033] The base 1 serves as the fundamental support structure for the entire casting machine. The positioning seat 11 is fixed to the top of the base 1, providing a hinge point for the casting hopper 2, thus enabling its rotation. A telescopic cylinder 3 connects the base 1 and the casting hopper 2, utilizing the cylinder's telescopic characteristics to convert linear motion into rotational motion of the casting hopper 2 around the positioning seat 11, thereby achieving the tilting casting action. A safety lock 5 is installed on the bottom side of the base 1 away from the telescopic cylinder 3, allowing the casting hopper 2 to be locked during equipment maintenance or when idle. Compared to traditional casting machines, this structure achieves automated driving of the casting action, reducing manual labor intensity and improving casting efficiency. The safety lock 5 effectively prevents the casting hopper 2 from accidentally tilting when not in operation, ensuring operator safety and equipment stability, and enhancing equipment safety.

[0034] In this embodiment, as Figure 1 , Figure 2 As shown, the bottom end of the telescopic cylinder 3 is hinged to the base 1, and the piston end of the telescopic cylinder 3 is hinged to the casting hopper 2.

[0035] The bottom end of the telescopic cylinder 3 is hinged to the base 1, and the piston end is hinged to the pouring hopper 2. This double-hinged connection allows the force of the telescopic cylinder 3 to be flexibly transmitted to the pouring hopper 2 during the telescopic process, ensuring that the pouring hopper 2 can rotate stably around the positioning seat 11 when under force. This smoothly converts the linear telescopic motion of the telescopic cylinder 3 into the rotational motion of the pouring hopper 2. Compared with the fixed connection, the hinged connection significantly improves the flexibility and stability of the tilting action of the pouring hopper 2, reduces resistance and jamming during the movement, makes the tilting angle control of the pouring hopper 2 more precise, ensures the stability of the pouring process, and extends the service life of various components of the equipment.

[0036] Specifically, such as Figure 1 , Figure 2 As shown, a guide pipe 4 is installed on one side of the base 1. When the pouring hopper 2 is pouring, the liquid flows downward through the guide pipe 4 to carry out a precise pouring operation.

[0037] A guide pipe 4 is installed on one side of the base 1, corresponding to the pouring port of the pouring hopper 2. When the pouring hopper 2 tilts for pouring, the molten metal flows downward along the guide pipe 4 due to its own gravity and the tilting force of the pouring hopper 2. The guide pipe 4 constrains and guides the flow path of the molten metal, achieving precise pouring. This effectively prevents the molten metal from splashing and spilling during the pouring process. Compared with pouring machines without a guide structure, this significantly improves the accuracy of molten metal pouring, reduces metal waste, increases material utilization, ensures a clean pouring environment, reduces cleaning costs, and improves the quality of castings.

[0038] Furthermore, such as Figure 4 As shown, a funnel-shaped opening 41 is provided at the top of the guide tube 4.

[0039] The funnel-shaped opening 41 at the top of the guide pipe 4 has a flared structure. Its large diameter design increases the receiving area for the molten metal poured from the pouring hopper 2. When the molten metal flows out of the pouring hopper 2, the funnel opening 41 guides the molten metal to flow more smoothly and quickly into the guide pipe 4, reducing overflow and splashing at the inlet of the guide pipe 4. This further optimizes the molten metal introduction process. Compared with a conventional straight-cylinder inlet guide pipe, the funnel opening 41 makes the introduction of molten metal smoother, improves the continuity and stability of the pouring process, reduces safety hazards and material waste caused by molten metal overflow, and improves pouring efficiency and quality.

[0040] Furthermore, the inner wall of the guide pipe 4 is provided with a spiral guide groove with a lead of 50-100mm and a depth of 3-5mm, which is used to guide the molten metal to form a rotating flow and reduce turbulence and splashing during pouring.

[0041] The spiral guide grooves on the inner wall of the guide tube 4 have a specific lead of 50-100mm and a depth of 3-5mm. When the molten metal flows inside the guide tube 4, it comes into contact with the inner wall of the spiral guide grooves and is constrained and guided by the spiral grooves, causing the flow direction of the molten metal to change, thus forming a rotating flow. The formation of the rotating flow can change the flow field distribution inside the molten metal and reduce the degree of turbulence. Compared with ordinary guide tubes, the design with spiral guide grooves can significantly reduce turbulence and splashing of molten metal during pouring, allowing the molten metal to flow into the mold in a more stable state. This effectively avoids defects such as porosity and inclusions in the casting caused by turbulence, improves the surface and internal quality of the casting, and increases the casting yield.

[0042] Furthermore, such as Figure 3 As shown, the safety lock 5 includes a support column 51. The bottom end of the support column 51 is rotatably connected to the base 1 via a pin 52. A U-shaped plate 21 is installed at the bottom of the pouring hopper 2 near the top of the support column 51. The top of the support column 51 is locked in place by the U-shaped plate 21 and secured by a locking bolt 22.

[0043] The support column 51 of the safety lock 5 is rotatably connected to the base 1 via a pin 52, allowing the support column 51 to switch between upright and lowered states. When the equipment requires maintenance or is idle, the support column 51 is erected, its top end locking into the U-shaped plate 21 at the bottom of the pouring hopper 2. Then, by tightening the locking bolts 22, the support column 51 and the U-shaped plate 21 are securely connected, thereby restricting the rotation of the pouring hopper 2 and locking it. This provides a reliable safety protection measure for the equipment. Compared to pouring machines without a safety locking structure, it effectively prevents the pouring hopper 2 from accidentally tilting during equipment maintenance or unexpected power outages, ensuring the personal safety of operators, avoiding equipment damage and production accidents caused by the tilting of the pouring hopper 2, and enhancing the safety and reliability of equipment operation.

[0044] Furthermore, such as Figure 3 As shown, fixing plates 521 are welded to both ends of the pin 52, and the bottom of the fixing plates 521 is welded and fixed to the base 1.

[0045] Fixed plates 521 are welded to both ends of the pin 52. The bottom of the fixed plates 521 is welded to the base 1. This welding connection method firmly fixes the pin 52 to the base 1, making the rotational connection between the support column 51 and the base 1 more stable and enhancing the overall strength and stability of the safety lock 5. Compared with a simple rotational connection, the addition of the welding structure of the fixed plates 521 can effectively prevent the pin 52 from loosening or shifting during use, ensuring that the safety lock 5 can reliably withstand the weight and external force of the pouring bucket 2 in the locked state, improving the service life and safety of the safety lock 5, and ensuring the long-term stable operation of the equipment.

[0046] Furthermore, such as Figure 3As shown, a locking hole 511 is provided on one side of the top of the support column 51, and one end of the locking bolt 22 passes through the U-shaped plate and is threadedly connected to the locking hole 511.

[0047] A locking hole 511 is provided on one side of the top of the support column 51. When the top of the support column 51 is engaged with the U-shaped plate 21, one end of the locking bolt 22 passes through the U-shaped plate 21 and is threadedly connected to the locking hole 511. By tightening or loosening the locking bolt 22, the support column 51 and the U-shaped plate 21 are secured or separated, thereby controlling the locking and unlocking states of the safety lock 5. The threaded connection method is simple and quick to operate. Compared with other complex connection methods, it allows operators to quickly lock and unlock the safety lock 5, improving the convenience of equipment maintenance and use. At the same time, the threaded connection has good tightness and reliability, ensuring that the safety lock 5 remains firmly connected in the locked state, ensuring equipment safety.

[0048] When using the tilting casting machine for metal casting of this utility model, first ensure that the equipment is in a safe state. At this time, the support column 51 of the safety lock 5 is in the lowered state, and the operator pours the molten metal to be poured into the casting hopper 2.

[0049] After preparation, the pouring operation begins. The telescopic cylinder 3 is activated, and its piston end begins to extend and retract under the pressure of the air inside the cylinder. Because the bottom of the telescopic cylinder 3 is hinged to the base 1, and the piston end is hinged to the pouring hopper 2, this double-hinged connection allows the linear extension and retraction of the telescopic cylinder 3 to be smoothly converted into the rotational motion of the pouring hopper 2 around the positioning seat 11. As the telescopic cylinder 3 extends or retracts, the pouring hopper 2 gradually tilts around the positioning seat 11, and the molten metal begins to flow under the influence of gravity.

[0050] When the pouring hopper 2 is tilted to the appropriate angle, the molten metal flows out from it. At this point, the guide pipe 4 installed on one side of the base 1 begins to function. The molten metal first flows into the funnel opening 41 at the top of the guide pipe 4. The flared structure of the funnel opening 41 increases the receiving area, guiding the molten metal smoothly into the guide pipe 4. After entering the guide pipe 4, the molten metal flows downward along the pipe with spiral guide grooves on the inner wall. The spiral guide grooves, with a specific lead of 50-100mm and a depth of 3-5mm, constrain and guide the molten metal, causing it to form a rotating flow, reducing turbulence and splashing. Finally, the molten metal flows into the mold in a stable and precise manner, completing the pouring operation.

[0051] After pouring is completed, the telescopic cylinder 3 moves in the reverse direction, causing the pouring hopper 2 to return to its initial position. To ensure equipment safety and prevent the pouring hopper 2 from accidentally tilting during equipment maintenance or when idle, the operator erects the support column 51 of the safety lock 5, so that its top end is locked in the U-shaped plate 21 at the bottom of the pouring hopper 2. Then, the locking bolt 22 is threaded through the U-shaped plate 21 and connected to the locking hole 511 at the top of the support column 51. The locking bolt 22 is tightened to firmly connect the support column 51 to the U-shaped plate 21, thereby locking the pouring hopper 2. This completes the entire pouring process.

[0052] Finally, it should be noted that the electronic components in the telescopic cylinder 3 and other components in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
