Description

Technical Field

[0001] This utility model relates to the field of metal casting, specifically to an automatic quantitative casting equipment for zinc alloy ingots. Background Technology

[0002] Zinc alloys, with their excellent casting properties, mechanical properties, and corrosion resistance, are widely used in many industries such as automotive, electronics, and machinery manufacturing. For example, in the automotive manufacturing field, zinc alloys are often used to manufacture key components such as engine blocks and gearbox housings. However, there are various zinc alloy casting equipment on the market. Some traditional casting equipment uses a method of manually scooping molten zinc and then casting it, such as using a casting ladle to scoop molten zinc from the holding furnace and pour it into the ingot mold of a linear casting machine. This method has many drawbacks. On the one hand, manual operation makes it difficult to accurately control the casting volume, resulting in poor product quality consistency, and on the other hand, it has low production efficiency and cannot meet the needs of large-scale industrial production. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide an automatic quantitative casting equipment for zinc alloy ingots to solve the technical problem that it is difficult to accurately control the casting volume manually during the casting process of existing equipment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic quantitative casting device for zinc alloy ingots, comprising a housing, a connector rotatably connected to one side wall of the housing, a rotating bearing fixedly connected inside the connector, a rotating shaft disposed inside the rotating bearing, one end of the rotating shaft being outside the housing, and the other end of the rotating shaft being inside the housing, a crucible rack for placing crucibles being fixedly connected to the end of the rotating shaft outside the housing, and the other end of the rotating shaft away from the crucible rack not connected to the housing, a mounting frame rotatably connected to the side wall of the end of the rotating shaft inside the housing, a rotating motor for controlling the rotation of the rotating shaft being fixedly connected to the mounting frame, two limiting posts for restricting the rotation of the mounting frame along the axial direction of the rotating shaft being fixedly connected inside the housing, a measuring groove being provided on the side of one of the limiting posts facing the mounting frame, a measuring block being slidably connected in the measuring groove, a force sensor being disposed between the bottom end of the measuring block and the groove, a linkage block being fixedly connected on the side of the measuring block facing the mounting frame, and a groove for the sliding of the linkage block being provided on the mounting frame.

[0005] By adopting the above technical solution, and through the connector combined with structures such as limiting posts, measuring slides, measuring blocks and force sensors, the remaining material in the crucible can be measured, thereby achieving quantitative casting. Through the cooperation of the mounting frame, rotating shaft and rotating motor, the crucible angle can be precisely controlled, reducing errors caused by manual operation, and achieving automatic casting while ensuring measurement accuracy.

[0006] Furthermore, a traveling wheel is provided at the bottom of the housing, and a traveling motor for controlling the rotation of the traveling wheel is provided inside the housing.

[0007] By adopting the above technical solution, the automatic quantitative casting equipment for zinc alloy ingots is equipped with autonomous operation capability by controlling the rotation of the traveling wheels through the traveling motor, and can cast different molds without manual operation.

[0008] Furthermore, all the limiting posts are perpendicular to the horizontal plane, and the mounting bracket is disposed between two limiting posts.

[0009] By adopting the above technical solution, the rotation of the motor around the shaft during operation is prevented.

[0010] Furthermore, the housing is equipped with multiple counterweights.

[0011] By adopting the above technical solution, the counterweight can adjust the center of gravity of the equipment, ensuring the stability of the equipment during operation.

[0012] Furthermore, the crucible is provided with lifting lugs for hoisting the crucible, and the crucible is provided with a discharge nozzle for convenient material discharge.

[0013] By adopting the above technical solution, the lifting lugs can facilitate the lifting of the crucible. The lifting lugs can be used to easily place the crucible on or remove it from the crucible rack using lifting equipment. The discharge nozzle design on the crucible can guide the flow direction of the zinc alloy melt, making the melt more concentrated and stable during the casting process and preventing material waste.

[0014] Furthermore, a first placement groove for placing the crucible discharge nozzle is provided on one side of the mounting frame, and a second placement groove for placing the crucible lifting lug is provided on both sides of the mounting frame adjacent to the first mounting groove.

[0015] By adopting the above technical solution, the first placement groove positions and fixes the discharge nozzle, ensuring that the discharge nozzle will not shake during the casting process and guaranteeing accurate casting position. The second placement groove further prevents the crucible from shaking by restricting the lifting lugs.

[0016] In summary, the present invention has the following main advantages: 1. This utility model, through a connector combined with a limiting post, a measuring slide, a measuring block and a force sensor, etc., realizes the measurement of the crucible residue, thereby achieving quantitative casting. Through the cooperation of the mounting frame, the rotating shaft and the rotating motor, the crucible angle is precisely controlled, reducing the error caused by manual operation, and realizing accurate measurement and automatic casting. 2. This utility model, through the lifting lug and the second mounting groove, the discharge nozzle and the first mounting groove, ensures that the discharge nozzle will not shake during the casting process, thus guaranteeing accurate casting position.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] In this example: An automatic quantitative casting equipment for zinc alloy ingots, such as Figure 1-6As shown, the device includes a housing 1. A connector 2 is rotatably connected to one side wall of the housing 1. The connector 2 is a ring, and two rotating shafts are symmetrically fixedly connected to its outer wall. A rotating bearing 3 is fixedly connected inside the connector 2. The inner and outer rings of the rotating bearing 3 are tightly fitted with the rotating shaft 4 and the connector 2, respectively, which can effectively reduce the frictional resistance when the rotating shaft 4 rotates. The rotating shaft 4 is set inside the rotating bearing 3. The rotating shaft 4 is made of high-strength alloy material and its surface is polished to ensure smoothness during rotation. One end of the rotating shaft 4 is outside the housing 1, and the other end of the rotating shaft 4 is inside the housing 1, ensuring... The installation and operation of the external crucible rack 5 are unaffected by the shell 1, while also providing protection for the internal transmission structure, preventing the high temperature of the external molten metal from affecting the internal structure. A crucible rack 5 for placing the crucible 6 is fixedly connected to one end of the rotating shaft 4 outside the shell 1. The crucible rack 5 can stably fix the crucible 6, ensuring stability during casting. The other end of the rotating shaft 4, away from the crucible rack 5, is not connected to the shell 1. If connected, the rotating shaft 4 cannot rotate around the horizontal centerline of the connector 2, affecting subsequent functions. A mounting bracket 7 is rotatably connected to the side wall of the end of the rotating shaft 4 inside the shell 1, providing support for subsequent structures. A stable installation platform is provided. A rotary motor 8 for controlling the rotation of the rotating shaft 4 is fixedly connected to the mounting frame 7. The rotary motor 8 and the rotating shaft 4 are connected via a reducer. Two limiting posts 9 are fixedly connected inside the housing 1 to restrict the axial rotation of the mounting frame 7 along the rotating shaft 4. The limiting posts 9 are solid steel columns rigidly connected to the bottom of the housing 1 via bolts to ensure stable limiting effect. One of the limiting posts 9 has a measuring groove 10 on the side facing the mounting frame 7. The measuring groove 10 has a T-shaped cross-section to prevent the measuring block 11 from derailing during sliding. The measuring groove 10 is slidably connected... A measuring block 11 is provided, which is made of wear-resistant alloy material with high surface smoothness to reduce friction during sliding. A force sensor 12 is provided between the bottom end of the measuring block 11 and the slide groove 14. A linkage block 13 is fixedly connected to the side of the measuring block 11 facing the mounting frame 7. The mounting frame 7 has a slide groove 14 for sliding the linkage block 13. The linkage block 13 and the slide groove 14 of the mounting frame 7 are fitted with a clearance to ensure the synchronization of the two when they are linked. When the mounting frame 7 moves upward, the measuring block 11 can be driven to move upward through the linkage block 13. The measuring block 11 pulls the force sensor 12 to realize the measurement of the crucible 6. See Figure 1 , Figure 3 , Figure 4 The bottom of the housing 1 is provided with a traveling wheel 15, and the housing 1 is provided with a traveling motor 16 for controlling the rotation of the traveling wheel 15. The traveling motor 16 and the traveling wheel 15 are connected by gear transmission, which can realize the movement of the equipment and enable the equipment to move automatically to cast different molds. See Figure 3 , Figure 4 The limiting posts 9 are all perpendicular to the horizontal plane. The vertically arranged limiting posts 9 can form a symmetrical constraint force on the mounting frame 7, ensuring that the mounting frame 7 is subjected to balanced force. The mounting frame 7 is arranged between two limiting posts 9. This clamping structure can effectively limit the rotation of the mounting frame 7 around the rotation axis 4 and improve the stability of the equipment during operation. See Figure 3 , Figure 4 The housing 1 is equipped with multiple counterweights 17. The counterweights 17 can be flexibly adjusted in position according to the equipment's center of gravity requirements to ensure that the equipment remains balanced during movement and operation. See Figure 7 The crucible 6 is provided with lifting lugs 20 for hoisting the crucible 6. The lifting lugs 20 and the crucible 6 are integrally formed, which has high strength and can safely support the crucible 6 under high temperature conditions, making it convenient for hoisting and moving the crucible 6. The crucible 6 is provided with a discharge nozzle 21 for convenient discharge. The discharge nozzle 21 is designed with an inclined shape and the end is tapered, which can accurately control the speed and direction of the molten liquid flow. See Figure 1 The mounting frame 7 has a first placement groove 18 on one side for placing the crucible 6 discharge nozzle 21. The shape of the first placement groove 18 matches the discharge nozzle 21, and the inner wall is provided with a high-temperature resistant silicone pad to prevent the discharge nozzle 21 from rigidly contacting the mounting frame 7 and to limit the shaking of the discharge nozzle 21. The mounting frame 7 has a second placement groove 19 on both sides adjacent to the first mounting groove for placing the crucible 6 lifting lug 20. By restricting the lifting lug 20, the stability of the crucible 6 is ensured, thereby ensuring the stability of the crucible 6 during casting. The implementation principle of this embodiment is as follows: First, the crucible 6 is hoisted into the mounting frame 7 using the lifting lug 20. Simultaneously, as the crucible 6 is placed on the crucible rack 5, the crucible 6 and the molten metal inside are subjected to gravity and move downwards, thus causing the mounting frame 7 to move downwards. The mounting frame 7 drives the rotating shaft 4 to rotate around the horizontal centerline of the connector 2. The other end of the rotating shaft 4 drives the mounting frame 7 to move upwards. The upward movement of the mounting frame 7 drives the linkage block 13 to move upwards, which in turn drives the measuring block 11 to move upwards. The measuring block 11 pulls the force sensor 12, thus measuring the weight of the crucible 6 and the molten metal. Then, the traveling motor 16 controls the traveling wheels 15 to move the equipment to the mold. Then, the rotating motor 8 drives the rotating shaft 4 to rotate. When the rotating motor 8 starts, the inertia of the rotating shaft 4 causes the rotating motor 8 to drive the mounting frame 7 downwards. The mounting bracket 7 rotates around the rotating shaft 4, but is fixed in place by the limiting post 9. This allows the rotating motor 8 to drive the rotating shaft 4 to rotate, which in turn drives the mounting bracket 7 to rotate. The rotation of the mounting bracket 7 causes the crucible 6 to rotate, allowing the molten metal to be poured into the mold through the discharge nozzle 21. As the amount of molten metal decreases, the weight on the end of the rotating shaft 4 closest to the mounting bracket 7 decreases, causing the end of the rotating shaft 4 closest to the mounting bracket 7 to start rotating upwards. Simultaneously, the end of the rotating shaft 4 furthest from the mounting bracket 7 rotates downwards, thereby reducing the tension on the force sensor 12. The reduced tension on the force sensor 12 is the weight of the molten metal poured into the mold. When the set weight is reached, the rotating motor 8 rotates back, controlling the crucible 6 to rotate back and stop casting. Finally, the traveling motor 16 controls the traveling wheel 15 to move to the next mold for casting.
