Description

Technical Field

[0001] The utility model relates to the technical field of inductor production, in particular to an inductor die-casting device. Background Art

[0002] Inductor, also known as choke, reactor, dynamic reactor, is a component that can convert electrical energy into magnetic energy and store it. The structure of the inductor is similar to that of a transformer, but it has only one winding. The inductor has a certain inductance, it only hinders the change of current, and is widely used in various fields such as machinery and electricity. One-piece molded inductor is one type of inductor, generally including a winding and a seat wrapped around the outside of the winding. During production, the winding is wrapped with metal powder and then die-casted. Pins are connected to both ends of the winding, and the pins extend from the side of the seat to the outside of the seat. The die-casting mold of the inductor generally includes an upper mold, a middle mold and a lower mold, wherein the upper mold and the lower mold are used for pressing the upper and lower surfaces of the inductor respectively, and the middle mold is used to constrain the side shape of the inductor. The middle mold has a forming hole, and both the upper mold and the lower mold have a forming column that can be inserted into the forming hole. When the one-piece molded inductor is die-cast, the coil is placed in the forming mold, and then the powder raw material is injected into the forming mold, and then the mold is pressed together by the die-casting equipment to finally form it. At present, after the inductor is die-casted, the staff needs to take the inductor out of the mold molding cavity. The operation process is relatively cumbersome and affects the work efficiency. In addition, during the die-casting process of the inductor, the position of the coil in the product needs to be ensured, which is generally achieved through the positioning structure of the coil in the mold (generally, the positioning structure of the coil is set in the middle mold), but this method requires redesigning the mold when producing inductors of different thicknesses (the positions of the inductor coils of different thicknesses relative to the overall product are different), which is costly.

DETAILED DESCRIPTION

[0023] In order to facilitate those skilled in the art to understand the present invention, the present invention will be further described in detail below in conjunction with specific embodiments and drawings.

[0024] Reference Figures 1 to 4The present embodiment provides an inductor die-casting device, comprising a chassis 1, a lower die seat 2 disposed on the chassis 1, a die adjustment mechanism 3 disposed at the bottom of the lower die seat 2, a plurality of guide support columns 21 disposed on the lower die seat 2, an upper die seat 4 movably connected to the guide support columns 21, a bearing seat 22 disposed on the top of the supporting guide columns, and a pressing drive mechanism 5 disposed on the bearing seat 22 for driving the upper die seat 4 to move in a vertical direction. When performing a die-casting operation, the lower die of the die-casting die is fixed on the lower die seat 2, and the upper die of the die-casting die is fixed on the bottom of the upper die seat 4.

[0025] The mold adjustment mechanism 3 includes a fixed base 31 arranged at the bottom of the lower mold base 2, an adjustment bracket 32 ​​arranged at the bottom of the fixed base 31, a lifting plate 33 movably connected to the adjustment bracket 32, a plurality of adjustment connecting rods 34 connected to the lifting plate 33 for adjusting the mold, and a driving assembly 35 for driving the lifting plate 33 to move in the vertical direction. The upper end of the adjustment connecting rod 34 passes through the lower mold base 2 and extends to the upper part of the lower mold base 2. A through hole for the adjustment connecting rod 34 to pass through is provided at the position of the lower mold base 2 corresponding to the adjustment connecting rod 34. The upper end of the adjustment connecting rod 34 is connected and fixed to the middle mold of the die-casting mold. Under the drive of the driving assembly 35, the lifting plate 33 moves in the vertical direction, driving the adjustment connecting rod 34 to move in the vertical direction, so that the height of the middle mold can be adjusted.

[0026] In this embodiment, the lower end of the adjusting link 34 passes through the lifting plate 33 and extends to the bottom of the lifting plate 33. The adjusting link 34 and the lifting plate 33 are movably connected, and a limit head 36 is provided at the lower end of the adjusting link 34. A spring is connected between the middle mold and the lower mold of the die-casting mold for producing the inductor. Under the action of the spring, the middle mold moves upward, so that the adjusting link 34 also moves upward. When the limit head 36 contacts the lifting plate 33, the middle mold reaches the highest position, which is the initial height of the middle mold. Therefore, the height of the lifting plate 33 can be adjusted by the driving component 35, so that the initial height of the middle mold (the initial height under the action of the spring elastic force) can be adjusted. After the inductor is die-cast, the driving assembly 35 drives the lifting plate 33 to move downward, and the lifting plate 33 pulls the adjusting link 34 to move the middle mold downward. At this time, the molding column of the lower mold moves upward relative to the middle mold and passes through the molding hole of the middle mold, so that the product and the middle mold are separated. At this time, the product can be easily taken away, and the material is convenient to take. After the material is taken, the driving assembly 35 drives the lifting plate 33 to reset, and the middle mold is also reset under the action of the spring force. At the same time, since the coil is positioned by the middle mold and the lower mold is fixed, when producing inductors of different thicknesses, the distance between the middle mold and the lower mold can be adjusted by adjusting the initial height of the middle mold, thereby changing the distance between the molding column of the coil and the lower mold (that is, the position of the coil relative to the whole product), and flexibly adapting to the die-casting of inductors of different thicknesses. The middle mold has a certain thickness to facilitate the production of inductors of different thicknesses.

[0027] The driving assembly 35 includes a driving motor 351, a lead screw 352 connected to the output end of the driving motor 351, and the lead screw 352 is connected to the lifting plate 33. The driving motor 351 can be a servo motor to accurately control the position of the lifting plate 33, thereby accurately controlling the position of the middle mold.

[0028] The adjustment bracket 32 ​​includes a plurality of guide fixing columns 321 connected to the bottom of the fixing seat 31, a fixing plate 322 connected to the bottom of the guide fixing columns 321, and the driving assembly 35 is disposed on the fixing plate 322. In this embodiment, four guide fixing columns 321 are provided and arranged in a rectangular shape.

[0029] A measuring assembly 37 is provided on one side of the fixing plate 322, and the measuring assembly 37 includes a connecting piece 371 connected to the fixing plate 322 and an electronic ruler 372 connected to the connecting piece 371. In a specific implementation, the electronic ruler 372 can be used to measure the height of the lifting plate 33, so as to more accurately control the position of the middle mold.

[0030] In this embodiment, the pressing drive mechanism 5 is a hydraulic mechanism, which includes a cylinder 51, a core shaft 52 connected to the cylinder 51, a cover body connected to the top of the cylinder 51, and a full oil valve 53 connected to the cover body.

[0031] The chassis 1 is provided with a first oil tank 6 and a delivery pump 7 connected to the first oil tank 6, and the delivery pump 7 is connected to the pressing drive mechanism 5. The delivery pump 7 can deliver the oil in the first oil tank 6 to the cylinder 51. In this embodiment, a second oil tank is also connected to one side of the weighing seat.

[0032] A cooler 8 is provided on one side of the first oil tank 6. The cooler 8 can cool the oil so that the oil is at a suitable operating temperature.

[0033] There are two adjusting connecting rods 34 , which are respectively arranged on two opposite sides of the lifting plate 33 , so that the lifting plate 33 can pull the middle mold on both sides at the same time, and the overall force is more uniform.

[0034] The chassis 1 is provided with a function panel 23. The function panel 23 is provided with a screen and function keys for displaying and adjusting device parameters. The chassis 1 is provided with a distribution box, which is connected to various electrical components of the device.

[0035] When performing die-casting production, first, the upper mold of the forming mold is fixed to the bottom surface of the upper mold base 4, the lower mold and the middle mold are fixed to the lower mold base 2, and the upper end of the adjusting connecting rod 34 is connected to the middle mold. According to the specifications of the inductor produced, the initial position of the lifting plate 33 (i.e., the initial position of the middle mold) is adjusted by the driving component 35. During the molding process, the coil is placed on the middle mold, and then the powder is injected into the through hole of the middle mold. The driving mechanism drives the upper mold base 4 to move downward, and the molding part of the upper mold is inserted into the through hole of the middle mold, and cooperates with the molding part of the lower mold to press the inductor into shape. After the inductor is formed, the driving component 35 drives the lifting plate 33 to move downward, and the adjusting connecting rod 34 moves downward under the drive of the lifting plate 33, thereby pulling the middle mold downward, and the inductor is removed from the middle mold. At this time, the inductor can be quickly removed to complete a molding process.

[0036] The utility model is provided with a mold adjustment mechanism 3, whose driving component 35 can drive the lifting plate 33 to move in the vertical direction, and drive the middle mold of the die-casting mold to move by adjusting the connecting rod 34, so that after the inductor is formed, the middle mold can be driven by the driving component 35 to quickly move down to make the inductor disengage, which is convenient for quick removal and improves the working efficiency. At the same time, the initial height of the lifting plate 33 can be accurately adjusted by the driving component 35, so as to change the relative height of the middle mold and the lower mold, that is, change the height of the coil relative to the lower mold, flexibly adapt to the production of inductors of different thicknesses, and no longer need to develop molds for inductors of different thicknesses separately, saving costs.
