Description

Technical Field

[0001] The utility model relates to the technical field of casting demoulding, in particular to a modeling robot used for demoulding a casting mold. Background Art

[0002] Casting molds are the core tools in the casting process. They play a key role in shaping molten metal and forming castings with specific shapes and sizes after cooling and solidification. These molds are usually composed of a mold body, a cavity, a gate and a vent. The mold body constitutes the main structure, the cavity is the space filled with metal, the gate is the channel for the metal to enter the cavity, and the vent is responsible for discharging the gas in the mold. Depending on the casting method and material, casting molds can be divided into gravity casting molds, high-pressure casting molds (die casting molds), low-pressure casting molds, extrusion casting molds, as well as sand molds, metal molds, ceramic molds and resin molds.

[0003] Sand molds are low-cost and easy to operate, making them suitable for mass production; metal molds are strong and durable, making them equally suitable for mass production; ceramic molds have superior heat resistance and are suitable for precision casting; and resin molds, with their high precision, are particularly suitable for casting complex and delicate parts. In the casting process, the casting mold not only plays a molding role, ensuring the shape and dimensional accuracy of the casting, but also affects the microstructure and performance of the casting through its cooling effect, and prevents gas from forming pores or inclusions in the casting through the exhaust holes, thereby ensuring the quality and performance of the casting.

[0004] The traditional demolding method is manual demolding, where workers need to manually flip the mold to pour out the casting inside. For large or heavy molds, this is not only labor-intensive and time-consuming, affecting production efficiency, but also increases workers' physical exertion. At the same time, the speed and accuracy of manual demolding are limited by the workers' physical strength, experience and skill level, making it difficult to meet high-output production needs. In addition, due to the time-consuming and labor-intensive nature of manual demolding, companies often need to hire more workers, increasing labor costs. Long working hours may cause worker fatigue and increase the risk of operational errors. More importantly, during the manual demolding process, workers need to come into close contact with high-temperature molds and castings, facing direct injury risks such as burns and smashing. Improper operation may also cause serious accidents such as mold collapse, posing a serious threat to workers' lives. Therefore, the inefficiency and safety hazards of manual demolding limit the production line's production capacity and can no longer meet the modern manufacturing industry's demand for efficient and safe production.

[0020] The above-mentioned technical solution is adopted, in which the rotating shaft is fixedly connected to the clamping plate, and then the rotating shaft is rotationally connected to the slide plate, so that the rotating shaft can be driven to rotate by the motor, and then the rotating shaft is used to drive the clamping plate to rotate, so that when the clamping plate drives the clamping block to clamp the mold, it can drive the mold to rotate, and then facilitate demolding and flipping the mold.

[0021] A further improvement of the technical solution of the present utility model is that the inner cavities of the two slide grooves are slidably connected to one side of the connecting frame close to the support assembly.

[0024] By adopting the above technical solution, in this solution, the connecting frame is made of rubber material, so that when the workpiece collides with the inner wall of the connecting frame, the inner wall of the connecting frame can reduce scratches on the surface of the workpiece.

[0025] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

[0026] 1. The utility model provides a molding robot for demolding a casting mold.

At the same time, since the device can be automated, it can improve production efficiency and casting quality, thereby reducing scrap rate and rework rate, and further reducing production costs.

[0027] 2. The utility model provides a molding robot for demolding casting molds, which is fixedly connected to the docking block through a magnet block. When the electromagnet is energized, a magnetic force is generated.

Then, the controller controls the electric push rod 58 to operate, and the piston rod of the electric push rod 58 pushes the rotating assembly 57 toward the mold. The clamping assembly 574 is driven to enter the clamping cavity with the cooperation of the two rotating assemblies 57, and the lower cover of the mold can be clamped and separated from the workpiece with the cooperation of the two rotating assemblies 57. The vibration pump 53 is then operated to generate vibration, and then the lower cover of the mold is driven to vibrate, and then the sand remaining in the inner cavity of the upper cover can be cleaned. After the sand in the inner cavity of the lower cover of the mold is cleaned, the rotating shaft 573 is driven to rotate by the motor, and then the clamping plate 572 and the clamped lower cover of the mold are driven to rotate together. The threaded rod 3 is driven to operate by the motor, and the threaded rod 3 is used to drive the clamping assembly 5 to move in the direction away from the supporting assembly 7.
