Description

Technical Field

[0001] The invention relates to the technical field of inductor molding dies, in particular to a mold for injection molding an inductor. 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 hinders the change of current. If there is no current flowing through the inductor, it will try to hinder the current from flowing through it when the circuit is connected; if there is current flowing through the inductor, it will try to maintain the current when the circuit is disconnected. Inductors are also called chokes, reactors, and dynamic reactors. As a component that can convert electrical energy into magnetic energy and store it, inductors are widely used in consumer electronics, communications, automobiles, aerospace, and other fields. The one-piece molded inductor is increasingly favored in the field of electronic devices due to its small size, large current, and high production efficiency.

[0003] At present, one-piece molded inductors are mainly made of metal powder and coils, which are formed in sequence by cold pressing or by combining one cold pressing with a second hot pressing using an one-piece molded inductor mold. Specifically, the wound coil is placed in the mold cavity of the one-piece molded inductor mold, and fluid metal powder is injected into the mold cavity, and pressure is applied to the surface of the metal powder to form the inductor.

[0004] For example, the mold for injection molding an inductor disclosed in the Chinese invention patent publication number CN115870500A includes a power component, an upper mold component and a lower mold component, wherein: the upper mold component includes an upper mold bottom plate, an upper mold pressure plate and an upper mold plate, the upper mold bottom plate is movably arranged on the machine platform, an upper mold cavity is opened on the upper mold plate, and a plurality of upper ejector pins that can be inserted into or withdrawn from the upper mold cavity are provided on the upper mold pressure plate; the lower mold component includes a lower mold bottom plate, a lower mold pressure plate and a lower mold plate, the lower mold bottom plate is movably arranged on the machine platform, a lower mold cavity is opened on the lower mold plate, and a plurality of lower ejector pins that can be inserted into or withdrawn from the lower mold cavity are provided on the lower mold pressure plate; the power component is arranged on the upper mold component and / or the lower mold component, and is used to provide a driving force to drive the upper mold pressure plate and the lower mold pressure plate to move toward or away from each other. The mold for injection molding an inductor provided by the present invention can adjust the length of the upper ejector pin extending into the upper mold cavity and the length of the lower ejector pin extending into the lower mold cavity, and can clamp coils of different specifications.

[0005] When the above device is used for inductor injection molding, the component used for spraying metal powder may cause metal powder to splash during feeding, thereby affecting the feeding effect. The tightness of the connection between the upper mold and the lower mold is poor, which may cause metal powder to overflow during metal powder spraying for injection molding, resulting in material waste.

[0006] To this end, we propose a mold for an injection molding inductor to solve the above problems. Summary of the invention
