Description

Technical Field

[0001] The utility model relates to the technical field of magnetic core powder die-casting, in particular to a material unloading mechanism after magnetic core powder die-casting. Background Art

[0002] A magnetic core is a core component made of magnetic material, commonly used in the fields of electronics and electrical engineering, especially in devices that require electromagnetic energy conversion, storage or transmission. It is mainly composed of a mixture of various iron oxides and is made through a sintering process. It is a magnetic metal oxide. Common core materials include manganese-zinc ferrite and nickel-zinc ferrite. The manufacture of the core involves a powder metallurgy process, including powder mixing, molding, sintering and subsequent machining steps. With the advancement of technology, modern core design also focuses on miniaturization, lightweight and higher performance indicators to meet the growing demand for electronic products.

[0003] Magnetic core powder die casting is a production process in the field of powder metallurgy, especially suitable for manufacturing various types of magnetic components, such as transformer cores, inductor cores, etc. This process is different from traditional metal die casting because it does not involve the injection of molten metal, but uses magnetic powder (such as ferrite powder, sendust powder, neodymium iron boron powder, etc.) mixed with a binder (usually resin or other organic matter) for molding. The magnetic core powder die casting process is widely used in the electronics and power industries because it can accurately control the shape and performance of the magnetic core and is suitable for mass production.

[0004] After the magnetic core powder is die-cast, the semi-finished product has relatively low strength and needs to be sintered and solidified. Due to the strength problem of the semi-finished product, the magnetic core powder is usually unloaded by a unloading robot after die-casting. However, when the stamping rhythm of the die-casting machine changes during use, the robot needs to be stopped and programmed to adapt to the new stamping rhythm of the die-casting machine, which reduces production efficiency. Utility Model Content

[0005] The utility model aims to provide a feeding mechanism for magnetic core powder after die-casting, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a feeding mechanism for magnetic core powder after die-casting, comprising a die-casting machine, a transmission mechanism is fixedly installed on one side of the die-casting machine, a material-prying mechanism is fixedly installed on the bottom of the transmission mechanism, the transmission mechanism comprises a mounting frame, a first turntable is rotatably installed on one side of the mounting frame, a mounting rod is eccentrically installed on one side of the first turntable, two groups of sliders are fixedly installed on the outer wall of the mounting rod, a connecting rod is movably installed on the top of the mounting rod, the connecting rod is fixedly installed on one side of the die-casting machine, and the connecting rod is arranged between the two groups of sliders.

[0007] Preferably, the internal thread of the slider is connected with an adjusting screw.

[0008] Preferably, a flywheel is fixedly connected to one side of the first turntable.

[0009] Preferably, a first bevel gear is fixedly connected to one side of the flywheel, a second bevel gear is meshingly connected to one side of the first bevel gear, and the second bevel gear is fixedly connected to the top of the material-discharging mechanism.

[0010] Preferably, the material shifting mechanism includes a second turntable, a movable block is rotatably installed on one side of the second turntable, a shifting rod is fixedly installed on the top of the second turntable, four groups of sliding grooves are opened at equal angles inside the movable block, a material shifting plate is fixedly connected to the bottom of the movable block, and four groups of material shifting rods are fixedly installed at equal angles on the outer wall of the material shifting plate.

[0011] Preferably, the outer wall of the material moving rod is sleeved with a rubber sleeve.

[0012] Preferably, a conveyor belt is fixedly installed on one side of the die-casting machine.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the material unloading mechanism used for magnetic core powder after die-casting;

[0014] 1. The lifting and lowering of the die-casting head of the die-casting machine is used to drive the connecting rod to move up and down, and the connecting rod drives the displacement of the mounting rod. Through the cooperation between the first turntable and the mounting rod, the reciprocating up and down displacement of the mounting rod is converted into a unidirectional rotation of the first turntable. In the above process, the first turntable is driven to rotate by the mounting rod not continuously but in a pulsating manner. The inertia of the flywheel rotation is used to smooth the pulsation of the first turntable during rotation, reduce speed fluctuations, make the first turntable rotate more smoothly, and improve the uniformity and reliability of mechanical operation. Through the cooperation between the first bevel gear and the second bevel gear, the flywheel drives the material-dispensing mechanism to move intermittently. In this process, the two sets of sliders allow the connecting rod to have a certain activity space on the outer wall of the mounting rod to prevent the die-casting head from destroying the cooperation between the first turntable and the mounting rod when the stroke is greater than the diameter of the first turntable, and the position of the slider on the surface of the mounting rod is adjustable by adjusting the screw;

[0015] 2. The second turntable is set up to drive the movable block to rotate periodically with the cooperation of the lever and the slide. Specifically, each time the die-casting head of the die-casting machine repeats the movement, the lever rotates one circle, driving the movable block to rotate 90°, and then the movable block drives the material disc and the material lever to rotate, and the semi-finished products produced by the die-casting machine are pushed to the conveyor belt through the material lever. In this process, rubber sleeves are used to avoid contact between the material levers to prevent the material levers from damaging the semi-finished products. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The specific implementation method is as follows: the lifting and lowering of the die casting head of the die casting machine 1 drives the connecting rod 201 to move up and down, and the connecting rod 201 drives the displacement of the mounting rod 204. Through the cooperation between the first turntable 203 and the mounting rod 204, the reciprocating up and down displacement of the mounting rod 204 is converted into a unidirectional rotation of the first turntable 203. In the above process, the rotation of the first turntable 203 driven by the mounting rod 204 is not continuous, but pulsating. The inertia of the rotation of the flywheel 207 is used to smooth the pulsation of the first turntable 203 during rotation, reduce speed fluctuations, and make the first turntable 203 rotate in a unidirectional manner. The disk 203 rotates more smoothly, improving the uniformity and reliability of the mechanical operation, and the flywheel 207 drives the material-dispensing mechanism 3 to move intermittently through the cooperation between the first bevel gear 208 and the second bevel gear 209.
