Silicon steel sheets are a soft magnetic material with excellent electromagnetic properties. They are mainly used in the manufacture of cores for electromagnetic equipment such as motors and transformers. The main function of the motor core is to provide a magnetic circuit and realize the conversion of electrical energy and mechanical energy through electromagnetic induction. During the operation of the motor, the current passes through the coil to generate a magnetic field. This magnetic field interacts with the magnetic flux in the core to generate electromagnetic force, thereby driving the motor rotor to rotate or realize other mechanical actions.

The utility model puts the product into the conveying table, and then the threaded rod rotates to fix the product, and then the rotating motor drives the rotating disc to rotate, and then the rotating disc drives the clamping block to rotate, so that the product is stamped, so as to achieve the function of rotation transmission, and then the rotating disc drives the clamping block to rotate to the collection port, and then the threaded rod releases the product, so that the product enters the collection port for collection, thereby achieving the function of automatic rotation and feeding, which is conducive to saving manual labor and thus reducing labor cost expenditure.

[0004] In the production process of motor cores, stamping is used to process the raw materials into corresponding shapes. However, during the stamping process, due to the high deformation of the material and the close fit with the inner wall of the mold, the processed core parts are difficult to remove after stamping. This removal process not only requires a lot of manpower and time, but may also cause damage to the core or mold due to improper operation. Utility Model Content

[0005] The utility model aims to provide a motor core stamping die to solve the problem that the processed core parts are difficult to remove after stamping due to the high deformation of the material and the close fit with the inner wall of the die. This removal process not only requires a lot of manpower and time, but also may cause damage to the core or the die due to improper operation.

[0006] The utility model provides the following technical solution: a motor core stamping die, comprising a base, an inner cavity is formed inside the base, the upper top of the base is fixedly connected to a die body for processing raw materials, an inner bottom end of the die body is penetrated by an ejection hole, and the ejection hole is connected to the inside of the inner cavity, and an ejection component for ejecting the material inside the die body is provided on the outer side wall of the base.

[0007] By adopting the above solution, through the combination of the ejection assembly and the ejection hole, the processed motor core can be ejected from the mold body quickly and accurately.

An air control valve is arranged on the outer wall of the second discharge pipe, and the output flow rate of the gas can be flexibly adjusted as needed. The pressure gauge can monitor the pressure state of the compressed gas in real time, which helps to promptly discover and solve the problem of insufficient or excessive air pressure.

When in use, the power structure in the ejector assembly provides corresponding power to the ejector assembly, and then transports the power to the inside of the inner cavity through the second discharge pipe. At this time, the air pressure inside the inner cavity increases, which will push the ejector structure to move upward. At this time, the fixed plate will push the ejector rod to move upward by compressing the limit spring, thereby driving the ejector plate to move upward, so as to achieve the purpose of pushing the finished product inside the mold body to be removed.

[0029] like Figure 3As shown, the ejection assembly includes an ejection structure arranged inside the inner cavity 14 and a power structure for driving the ejection structure to work, the ejection structure includes an ejection rod 4 movably connected, the upper top of the ejection rod 4 is fixedly connected with an ejection plate 41, so that during use, the ejection rod 4 can drive the ejection plate 41 to achieve the ejection effect, the lower bottom end of the ejection rod 4 is fixedly connected with a fixing plate 43, and the upper top of the fixing plate 43 is fixedly connected with a limiting spring 44, so that after ejection, the ejection rod 4 and the ejection plate 41 can achieve automatic reset, the outer wall of the ejection rod 4 is movably sleeved with an anti-collision plate 42, the ejection plate 41 is movably connected to the inner top of the ejection hole 21, and the upper top of the limiting spring 44 is fixedly connected to the lower bottom end of the anti-collision plate 42.

[0030] like Figure 2 and Figure 3 As shown, the power structure includes an air compressor body 3 fixedly connected to the outer wall of the base 1, and the outer wall of the base 1 is located on one side of the air compressor body 3 and is provided with a gas pressure tank 32 for storing compressed gas. The output end of the air compressor body 3 is fixedly connected to a first discharge pipe 311 connected to the input end of the gas pressure tank 32, and the output end of the gas pressure tank 32 is fixedly connected to a second discharge pipe 34, and the end of the second discharge pipe 34 is fixedly connected to a transmission gas frame 36. The upper top of the transmission gas frame 36 is provided with a plurality of discharge holes 37 for facilitating the passage of gas, so that when the compressed gas enters the transmission gas frame 36, it can be discharged through the discharge holes 37 and enter the interior of the inner cavity 14.

[0031] like Figure 2 and Figure 4 As shown, the transmission gas frame 36 is fixedly connected to the inner bottom end of the inner cavity 14, and the inner bottom end of the inner cavity 14 is fixedly connected with a sealing ring 15 to prevent gas from escaping from the inner cavity 14 and causing insufficient pressure. The outer wall of the air pressure tank 32 is fixedly sleeved with a fixed bracket 33, and the outer wall of the fixed bracket 33 is fixedly connected to the outer wall of the base 1.

When the pressure is discharged, the ejection structure will automatically reset under the elastic action of the limit spring 44.
