Description

Technical Field

[0001] This utility model relates to a casting machine, and more particularly to a casting equipment for casting. Background Technology

[0002] A casting pouring machine, also known as a pouring device or casting machine, is mainly used to precisely inject molten metal (such as molten iron, molten steel, molten aluminum, etc.) into a casting mold or cavity to form the desired casting. It is an indispensable piece of equipment in casting production, playing a crucial role in improving casting quality, reducing scrap rates, and lowering production costs. Based on differences in structure and working principle, casting pouring machines can be classified into various types, such as tilting pouring machines, pneumatic pouring machines, and bottom-pouring pouring machines. These different types of pouring machines each have their own characteristics and are suitable for different casting scenarios and needs.

[0003] Tilting gating machines are mainly used for casting medium to large parts on air-pump and hydrostatic molding lines. Their key feature is the ability to tilt at a certain angle to evenly inject molten metal into the mold. With the application of servo and other control technologies, tilting gating machines have been successfully applied to casting small parts on high-productivity molding lines. The tilting gating machine is equipped with a pouring ladle / hopper to hold the molten metal. A tilting mechanism drives the ladle / hopper to rotate, allowing the molten metal to overflow from the spout and flow into the casting mold below. To ensure that the molten metal flows completely into the gate of the casting mold, the flow rate of the molten metal and the position of the gate must be kept stable. Therefore, the tilting axis of current tilting casting machines tends to be close to the gate. This ensures that the horizontal offset of the gate is small during the tilting process. However, this also results in a significant rise in the overall center of gravity of the casting ladle / hopper during the tilting process, and a large overall mass of the casting ladle / hopper. This leads to large real-time load changes in the tilting mechanism during the tilting process, requiring higher strength of materials and structure, especially a large load on the motor. This undoubtedly increases manufacturing and maintenance costs. Summary of the Invention

[0004] This invention provides a casting equipment; it solves the problem in the prior art where the overall center of gravity of the casting equipment rises significantly when it tilts, resulting in a significant increase in the load on the tilting mechanism.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a casting equipment, including a horizontally arranged truss and a truss cart, and further comprising:

[0006] A lifting base is fixed to the bottom of the truss vehicle. The lifting base is provided with horizontally distributed slide rails and servo screw assemblies. The distribution direction of the slide rails is perpendicular to the distribution direction of the truss.

[0007] A sliding seat is slidably mounted on the slide rail seat, and a screw nut that cooperates with the servo screw assembly is fixed on it. The bottom of the sliding seat is provided with two hanging plates that are hung down. Several positioning wheels are horizontally rotatably mounted on the inner side wall of the hanging plates. A casting gap is formed between the positioning wheels on the two hanging plates. One of the hanging plates is also provided with a servo motor, and the output shaft of the servo motor is provided with a gear.

[0008] The casting hopper has a semi-circular outer contour. The circumferential sidewall of the casting hopper can roll in contact with all the positioning wheels. The outside of the casting hopper is also provided with a half tooth fixed coaxially with it. The half tooth meshes with the gear. The casting hopper is provided with a casting nozzle facing the casting gap.

[0009] The truss and truss carriage used in this invention are conventional existing products, which can be customized according to the actual load and site conditions. The truss carriage can move the hoisting seat and its load, the pouring hopper, along the track on the truss. Metal molten filling equipment and several pouring molds can be set along the truss line. The pouring method of this invention is as follows: the truss carriage moves the hoisting seat and its load, the pouring hopper, above the mold to be poured. Then, the servo screw assembly starts to position the sliding seat according to the preset program, ensuring that the pouring nozzle on the pouring hopper is in the preset position. Then, the servo motor drives the gear to rotate, and the half-tooth drives the pouring hopper to rotate. The rotation axis of the pouring hopper is the center of its circumferential side wall. Therefore, as it rotates, the horizontal position of the pouring nozzle will continuously shift. For this reason, the servo screw assembly will continuously perform position feed compensation according to the preset program to ensure that the horizontal position of the pouring nozzle is on the preset path. This ensures that the molten metal can flow completely into the gate. Meanwhile, as the pouring hopper rotates and the molten metal flows out, the center of gravity of the whole does not rise but continues to slowly descend. Furthermore, since the weight of the pouring hopper is entirely borne by the positioning wheels, the load on the servo motor is very small. This not only reduces the purchase cost of the servo motor but also extends its service life.

[0010] Therefore, this utility model has the following characteristics compared with the prior art: 1. During the tilting process of the pouring hopper, the weight is entirely borne by the positioning wheel, so the load on the servo motor is very small, which can not only reduce the purchase cost of the servo motor, but also extend its service life; 2. During the tilting process of the pouring hopper, the servo screw assembly will continuously perform position feed compensation according to the preset program to ensure that the horizontal position of the pouring nozzle is on the preset path, so as to ensure that the molten metal can flow completely into the gate.

[0024] The truss and truss carriage used in this embodiment are conventional existing products, which can be customized according to the actual load and site conditions. The truss carriage can move the hoisting seat and its load, the pouring hopper, along the track on the truss. Metal molten filling equipment and several pouring molds can be set along the truss line. The pouring method in this embodiment is as follows: the truss carriage moves the hoisting seat and its load, the pouring hopper, above the mold to be poured. Then, the servo screw assembly starts to position the sliding seat according to the preset program, ensuring that the pouring nozzle on the pouring hopper is in the preset position. Then, the servo motor drives the gear to rotate, and the half-tooth drives the pouring hopper to rotate. The rotation axis of the pouring hopper is the center of its circumferential sidewall. Therefore, as it rotates, the horizontal position of the pouring nozzle will continuously shift. For this reason, the servo screw assembly will continuously perform position feed compensation according to the preset program to ensure that the horizontal position of the pouring nozzle is on the preset path. This ensures that the molten metal can flow completely into the gate.

Furthermore, since the weight of the pouring hopper is entirely borne by the positioning wheels, the load on the servo motor is very small. This not only reduces the purchase cost of the servo motor but also extends its service life.
