[0016] The processing technology of the forming device for preparing the magnetic core includes the following steps:

[0017] S1: External feeding equipment feeds the magnetic core powder into the top of the main mold through the feeding hopper. The powder covers the extrusion block to achieve gas isolation, so as to prevent gas from being fed into the powder gap during the extrusion process of the extrusion block;

[0018] S2: The thrust cylinder first drives the main mold to move back and forth, and the main mold will drive the slider to move synchronously on the housing. The main mold will drive the force plate to move synchronously. At this time, the guide groove on the housing will drive the driving gear plate and the moving block to move synchronously through the convex shaft on the force plate. The driving gear plate will drive the transmission gear to rotate, and the moving block will drive the loading plate to move back and forth through the rotating arm.

[0019] S3: The transmission gear drives the five cams to rotate via the rotating rod. Since the distal end points of the cams are located at different positions, the cams push the corresponding outer frames in sequence, causing the impact plates on the top of the outer frames to impact the bottom module in sequence, generating continuous vibration. When the impact plates are compressed, they drive the limit rods downward, and at the same time, the impact plates compress the return springs. When the impact plates move away from the inner wall of the bottom module, the return springs push the impact plates back to their original positions. The continuous vibration of the bottom module reduces the gas in the powder inside the main mold.

[0020] S4: The reciprocating loading plate will drive the cross bar to move synchronously, and the traction plates installed on both sides of the cross bar will move synchronously, and the positive push blocks at the ends of the cross bar will follow the movement. Since the traction plate slides and is obliquely inserted on the side plate frame, the traction plate will drive the side plate frame to slide along the fixed guide rail, and the cross bar and side plate frame will be used to vibrate and exhaust the powder in the main mold. At the same time, the moving positive push blocks and side plate frames can accelerate the powder to enter the molding cavity. When the powder exhaust operation is completed, the pressure cylinder will drive the guide frame and the extrusion block to move downward. At this time, the extrusion block will move into the molding cavity for extrusion molding to complete the molding of the magnetic core. Then the thrust cylinder pushes the main mold to the farthest point. During this process, the lifting cylinder can perform auxiliary operations. After that, the lifting cylinder will drive the bottom module to move downward, so that the magnetic core product in the molding cavity can be moved out. At the same time, the horizontally moving main mold will drive the magnetic core on the bottom module to move toward the contact plate, so that the contact plate can push out the processed magnetic core.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the molding device and process for preparing magnetic cores adopt an extrusion block structure in which powder is pre-embedded, and the powder is used to isolate the extrusion block from the outside air to prevent air from entering the powder gap during the extrusion process. In addition, vibration exhaust structures are provided on the upper and lower sides of the molding cavity of the device, which can effectively reduce the gas in the powder and improve the strength of the magnetic core structure after molding. At the same time, the upper vibration structure also has an auxiliary pushing effect. The specific contents are as follows:

[0022] 1. The extrusion block is set away from the inner wall of the main mold. The extrusion block is in the middle of the main mold, and the bottom surface of the extrusion block is set towards the top of the molding cavity. The two sides of the extrusion block are fixedly connected with symmetrically distributed guide frames. The top of the guide frame slides vertically through the guide rod on the top of the main mold. When the main mold is filled with powder, the powder will cover the extrusion block to form an air isolation. The pressure electric cylinder can drive the extrusion block to move through the guide frame, so that the extrusion block can perform extrusion molding operations in an air-isolated environment, thereby reducing the gas in the powder.

[0023] 2. An upper vibration structure for vibrating and pushing is embedded on the inner side of the top of the main mold. A two-way transmission mechanism for driving the vibration structure is slidably embedded on both sides of the main mold. A wave vibration module for vibrating the bottom of the main mold is installed inside the bottom module. The upper vibration structure and the wave vibration module are driven to run synchronously through the two-way transmission mechanism. At this time, the cross bar in the upper vibration structure drives the side plate frame to move obliquely back and forth through the traction plate. The cross bar and traction plate will vibrate the powder on the upper part of the molding cavity. At the same time, the cross bar and traction plate will push the powder into the molding cavity, and the wave vibration module will run in the bottom module, so that the bottom of the molding cavity of the main mold will vibrate synchronously for rapid exhaust.
