Description

Technical Field

[0001] This utility model relates to the technical field of motor end cover production equipment, and in particular to a rapid demolding device for casting motor end covers. Background Technology

[0002] With the rapid development of the motor industry, the market demand for motor end caps is increasing, placing higher requirements on their quality and production efficiency. In the field of motor manufacturing, motor end caps are important components, and their quality and production efficiency have a key impact on the overall performance and production progress of the motor. Currently, the commonly used processing technology for motor end caps is casting, which involves melting metal raw materials into liquid and pouring them into a mold. After cooling and solidification, the end caps are cleaned and obtained. This process has advantages such as easy machining, good shock absorption and wear resistance, low notch sensitivity, and good heat treatment performance. Therefore, there is a particular need for a quick demolding device for casting motor end caps.

[0003] However, the existing demolding process for motor end caps mainly relies on manual operation supplemented by simple demolding tools, which has many drawbacks. During the demolding process, due to the adhesion between the mold and the casting and the complex structural shape, a lot of time and manpower are often required to complete the demolding operation. This not only seriously limits production efficiency, but also increases the production cost of enterprises in the context of rising labor costs. In addition, the lack of a moving lifting device makes it difficult to ensure the uniformity of demolding force and direction during manual demolding, which can easily damage the casting and result in a high scrap rate. At the same time, the lack of a rotating adsorption device makes it difficult to remove some of the cast motor end caps, reducing production efficiency, increasing production costs, reducing overall economic benefits, and leading to a significantly higher scrap rate and low practicality.

By setting up the movable lifting assembly 6, not only are the skill requirements for operators reduced and personnel training costs decreased, but the labor intensity of operators is also greatly reduced, the working environment is improved, and the comfort and safety of work are enhanced, which helps to ensure the stable operation of production.

[0024] Furthermore, the support plate 605 is provided in two identical sets, and the two sets of support plates 605 are symmetrically distributed about the vertical center line of the connecting plate 606. The connecting plate 606 is fixedly connected between the support plates 605. By providing two sets of support plates 605, the connecting plate 606 is made more stable, ensuring that the whole will not be misaligned or shifted due to vibration.

[0025] Furthermore, the mounting holes 607, mounting base plate 608, electric cylinder 2 609, telescopic rod 2 610, and connecting block 611 are provided in four identical sets.

The mounting holes 607 are adapted to the electric cylinder 2 609. By providing four sets of mounting holes 607, mounting base plate 608, electric cylinder 2 609, telescopic rod 2 610, and connecting block 611, the connection stability between the connecting plate 606 and the punch 7 is enhanced, ensuring the lifting and lowering movement of the punch 7.

[0026] Furthermore, the punch 7 is located above the die 1, and the punch 7 and the die 1 are adapted to each other. By setting the punch 7 and the die 1, the punch 7 and the die 1 can be tightly closed.

[0027] Working Principle: Before use, operators first inspect the internal and external environment of the entire equipment to ensure a good working environment for the die 1, thus guaranteeing the health and safety of the operators. Operators then control two sets of electromagnetic slide rods 604 via a power switch, causing the electromagnetic slide rods 604 to slide on the fixed rod 603. Simultaneously, the fixed rod 603 slides on the slide rail 601. Because of the limit block 602, the fixed rod 603 and electromagnetic slide rods 604 will not slip off. At this point, the operator slides the punch 7 on the support plate 605. When the casting reaches directly above the die 1, it stops. At this point, the operator activates four sets of electric cylinders 609, which raises and lowers the telescopic rod 610, thereby raising and lowering the connecting block 611, and consequently lowering the punch 7. When the punch 7 closes with the die 1, molten metal is injected. After a period of time, when the casting is ready to be removed, the operator activates electric cylinders 609 again to return it to its initial state. Then, the operator controls the two sets of electromagnetic sliders 604 again via the power switch, causing the electromagnetic sliders 604 to slide on the fixed rod 603. The fixed rod 603 slides on the slide rail 601, stopping when the connecting plate 606 on the support plate 605 and the punch 7 are far from directly above the die 1. At this time, the operator starts the drive motor 502, which drives the active bevel gear 503 to rotate, thereby driving the driven bevel gear 504 to rotate, and then driving the rotating bend tube 505 to rotate. When the suction plate 510 rotates to directly above the cast motor end cover, it stops. At this time, the operator starts the electric cylinder 508, which drives the telescopic rod 509 to move downward, thereby driving the suction plate 510 to move downward, adsorbing the cast motor end cover and pulling it upward. The operator can then easily remove the cast motor end cover, reducing the labor intensity of the operator, improving the working environment, and enhancing the comfort and safety of the work. Finally, the operator only needs to repeat the above process to process all the motor end covers that need to be cast. The operation is simple and convenient. The operator only needs to reverse the above process to restore the device to its original state. At this time, the operator finally checks the internal and external environment of the device to complete all the operation processes. It has high practicality.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
