Description

Technical Field

[0001] The present invention relates to the technical field of molds, and specifically to an inductor forming mold and its usage method. Background Art

[0002] An inductor is a component that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to that of a transformer, but it has only one winding. An inductor has a certain inductance, and it only impedes the change of current. If the inductor is in a state without current passing through, when the circuit is switched on, it will attempt to impede the current from flowing through it; if the inductor is in a state with current passing through, when the circuit is switched off, it will attempt to maintain the current unchanged. Inductors are also known as chokes, reactors, and dynamic reactors.

[0003] When the existing inductor is hot-pressed and formed, after pressing the metal powder into an inductor, the inductor is very likely to adhere to the inner wall of the lower mold during hot pressing. It requires an operator to manually remove the inductor element from the lower mold. In this process, the efficiency is low, the risk is high, and it is inconvenient to use. Therefore, an inductor forming mold and its usage method are proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide an inductor forming mold and its usage method to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An inductor forming mold includes an upper mold. A heating plate is installed on the lower side of the upper mold. A plurality of stamping blocks are installed on the lower side of the heating plate. Guide columns are movably penetrated through the four sides of the upper mold. A second limiting block located above the upper mold is fixed to the top of the guide columns. A support plate is fixed to the bottom of the guide columns. A lower mold is installed on the top of the support plate. A plurality of forming cavities are opened on the top of the lower mold. Fixed frames located on both sides of the lower mold are fixed to the top of the support plate. A prompting component is arranged on one side of the fixed frame. A material pushing component is arranged on one side of the prompting component;

[0006] The material pushing component includes a cross plate. A plurality of sliding columns are fixed to the top of the cross plate. Two first chutes and a second chute are respectively opened on one side of the fixed frame. A sliding rod fixed to the bottom of the upper mold is slidably connected to the inner side of the first chute.

[0007] Preferably, a pressing plate is slidably connected to the inner side of the second chute. A second spring is connected between one side of the pressing plate and the inner side of the second chute.

[0008] Preferably, connecting rods are fixed to both sides of the top of the cross plate. The top of the connecting rods is fixed to one side of the bottom of the pressing plate.

[0009] Preferably, a plurality of third chutes are formed inside the lower die and located below the molding cavity, and the inner sides of the third chutes are seamlessly and slidably connected to the outer sides of the sliding columns.

[0010] Preferably, a push plate that is seamlessly and slidably connected to the inside of the molding cavity is fixed to the top of the sliding column, and the cross plate is located below the lower die.

[0011] Preferably, the prompting component includes two first connecting rings. A support rod is fixed to the bottom of the first connecting ring, and a second connecting ring is fixed to the bottom of the support rod.

[0012] Preferably, a limiting groove is provided on the inner wall of the first chute. A first limiting ring and a first limiting block are respectively fixed to the inner wall of the limiting groove, and the top of the second connecting ring is located below the first limiting ring.

[0013] Preferably, a switch is installed at the bottom of the limiting groove. A first spring is sleeved outside the switch, and two ends of the first spring are respectively connected to the second connecting ring and one side of the limiting groove.

[0014] Preferably, a warning light is installed on one side of the fixing frame, and the output end of the switch is electrically connected to the input end of the warning light.

[0015] The present invention also provides a method for using an inductor molding die, including the following steps:

[0016] S1. Inductor molding: Place the raw material for hot-pressing the inductor inside the molding cavity at the top of the lower die. Connect the upper die to a hydraulic device so that the upper die drives the heating plate and the stamping block to move towards the inside of the molding cavity, and hot-press the inductor through the cooperation of the stamping block and the molding cavity.

[0017] S2. Inductor pushing: When the inductor inside the molding cavity is molded, at this time, the sliding rod pushes the pressing plate to slide inside the second chute, and at the same time, the connecting rod slides inside the first chute. At this time, the second spring is compressed, and at the same time, the cross plate, the sliding column, and the push plate move downward. The push plate is located at the bottom of the molding cavity. At this time, the inductor is hot-pressed inside the molding cavity. When the upper die drives the sliding rod to move upward, at this time, the second spring pushes the pressing plate to slide inside the second chute, and at the same time, drives the connecting rod, the cross plate, the sliding column, and the push plate to move upward, and pushes out the inductor that has been molded inside the molding cavity.

[0018] S3. Offset prompting: When an offset occurs between the upper die and the lower die, at this time, the guide post cannot be inserted into the inside of the first chute. At this time, the bottom of the guide post abuts against the top of the first connecting ring. At this time, the first connecting ring pushes the support rod and the second connecting ring to slide downward inside the limiting groove. At this time, the second connecting ring compresses the first spring, and at the same time, the second connecting ring abuts against the contact point of the switch. At this time, the switch is triggered, causing the warning light to give a sound and light prompt.

[0019] Compared with the prior art, the present invention adopts the above technical solutions and has the following technical effects:

[0020] 1. The pressure plate is pushed by the sliding rod to slide inside the second chute, and at the same time, the connecting rod slides inside the first chute. At this time, the pushing plate is located at the bottom of the forming cavity. At this time, the inductor is hot-pressed and formed inside the forming cavity. When the upper mold drives the sliding rod to move upward, the second spring pushes the pressure plate to slide inside the second chute, and at the same time drives the connecting rod, the cross plate, the sliding column and the pushing plate to move upward, and pushes out the formed inductor inside the forming cavity, avoiding the operator from contacting the high-temperature inductor and the mold, eliminating the need for manual removal of the inductor element, reducing potential safety hazards, and improving the blanking efficiency.

[0021] 2. When there is an offset between the upper mold and the lower mold, the bottom of the guide post abuts against the top of the first connecting ring. At this time, the first connecting ring pushes the support rod and the second connecting ring to slide downward inside the limit groove. At the same time, the second connecting ring abuts against the contact point of the switch, and at this time the switch is triggered, causing the warning light to produce sound and light prompts, actively informing the operator that there is an offset between the upper mold and the lower mold at this time, and the mold needs to be maintained as soon as possible to avoid the production of defective inductors, reducing unnecessary losses and risks, and improving the product quality of the inductor.

The pressing plate 39 is slidably connected inside the second sliding groove 36, and a second spring 37 is connected between one side of the pressing plate 39 and the inside of the second sliding groove 36. Connecting rods 33 are fixed on both sides of the top of the cross plate 34, and the top of the connecting rod 33 is fixed to one side of the bottom of the pressing plate 39, avoiding operators from contacting the high-temperature inductor and the die, eliminating the need for manual removal of the inductor element, reducing potential safety hazards, and improving the blanking efficiency.

[0038] In order not to need to use other mechanical power equipment to push the inductor, a number of third chutes 38 located below the forming cavity 8 are provided inside the lower die 7. The inner side of the third chute 38 is seamlessly slidably connected to the outer side of the sliding column 35. At the same time, the cross plate 34, the sliding column 35 and the pushing plate 310 move downward. The pushing plate 310 is located at the bottom of the forming cavity 8.

[0039] In order to conveniently prompt the operator that the mold is defective, a prompt component is provided. The prompt component includes two first connection rings 22. The bottom of the first connection ring 22 is fixed with a support rod 23. The bottom of the support rod 23 is fixed with a second connection ring 25. A limiting groove 29 is provided on the inner wall of the first chute 32. The bottom of the guide post 4 abuts against the top of the first connection ring 22. At this time, the first connection ring 22 pushes the support rod 23 and the second connection ring 25 to slide downward inside the limiting groove 29.

The output end of the switch 27 is electrically connected to the input end of the warning lamp 21, avoiding the generation of defective inductors, reducing unnecessary losses and risks, and improving the product quality of the inductor.

[0040] Working principle: When inductors need to be hot-pressed and formed, place the raw materials for inductor hot-pressing and forming inside the forming cavity 8 at the top of the lower die 7. Connect the upper die 1 to the hydraulic equipment, so that the upper die 1 drives the heating plate 10 and the stamping block 11 to move inward towards the forming cavity 8. At this time, one side of the upper die 1 slides outside the guide post 4, and then the inductor is hot-pressed and formed by the cooperation of the stamping block 11 and the forming cavity 8. When the inductor inside the forming cavity 8 is formed, the slide bar 31 pushes the pressing plate 39 to slide inside the second chute 36, and at the same time makes the connecting rod 33 slide inside the first chute 32. At this time, the second spring 37 is compressed, and at the same time the cross plate 34, the slide column 35 and the pushing plate 310 move downward. The pushing plate 310 is located at the bottom of the forming cavity 8. At this time, the inductor is hot-pressed and formed inside the forming cavity 8. When the upper die 1 drives the slide bar 31 to move upward, the second spring 37 pushes the pressing plate 39 to slide inside the second chute 36, and at the same time drives the connecting rod 33, the cross plate 34, the slide column 35 and the pushing plate 310 to move upward, pushing out the formed inductor inside the forming cavity 8, avoiding operators from contacting the high-temperature inductor and the mold, eliminating the need for manual removal of inductor components, reducing safety hazards, and improving the blanking efficiency;

[0041] When an offset occurs between the upper die 1 and the lower die 7, the guide post 4 cannot be inserted into the first chute 32 at this time. The bottom of the guide post 4 abuts against the top of the first connecting ring 22. At this time, the first connecting ring 22 pushes the support rod 23 and the second connecting ring 25 to slide downward inside the limiting groove 29. At this time, the second connecting ring 25 compresses the first spring 26, and at the same time the second connecting ring 25 abuts against the contact point of the switch 27. At this time, the switch 27 is triggered, causing the warning light 21 to generate sound and light prompts, actively informing the operator that an offset has occurred between the upper die 1 and the lower die 7 at this time, and the mold needs to be maintained as soon as possible to avoid the generation of defective inductors, reducing unnecessary losses and risks, and improving the product quality of the inductors.

[0042] The present invention also provides a method for using an inductor forming mold, including the following steps:

[0043] S1. Inductor forming: Place the raw materials for inductor hot-pressing and forming inside the forming cavity 8 at the top of the lower die 7. Connect the upper die 1 to the hydraulic equipment, so that the upper die 1 drives the heating plate 10 and the stamping block 11 to move inward towards the forming cavity 8, and hot-press and form the inductor through the cooperation of the stamping block 11 and the forming cavity 8;

[0044] S2. Inductive feeding: When the inductor is formed inside the forming cavity 8, the sliding rod 31 pushes the pressing plate 39 to slide inside the second chute 36. At the same time, the connecting rod 33 slides inside the first chute 32, compressing the second spring 37. Meanwhile, the cross plate 34, the sliding column 35, and the pushing plate 310 move downward. The pushing plate 310 is located at the bottom of the forming cavity 8. At this time, the inductor is hot-pressed and formed inside the forming cavity 8. When the upper die 1 drives the sliding rod 31 to move upward, the second spring 37 pushes the pressing plate 39 to slide inside the second chute 36, and at the same time drives the connecting rod 33, the cross plate 34, the sliding column 35, and the pushing plate 310 to move upward, pushing out the formed inductor inside the forming cavity 8.

[0045] S3. Offset prompt: When an offset occurs between the upper die 1 and the lower die 7, the guide post 4 cannot be inserted inside the first chute 32. At this time, the bottom of the guide post 4 abuts against the top of the first connecting ring 22. The first connecting ring 22 pushes the support rod 23 and the second connecting ring 25 to slide downward inside the limit groove 29. The second connecting ring 25 compresses the first spring 26. At the same time, the second connecting ring 25 abuts against the contact of the switch 27, triggering the switch 27 to make the warning light 21 give sound and light prompts.
