Abstract

The invention relates to loudspeaker processing equipment, in particular to an injection molding device. The invention also relates to a loudspeaker processing technology, in particular to an injection molding technology. The injection molding device for a polymagnetic steel product comprises a positioning tool, an ejection tool and an injection mold. Ejection tool mandrils are arranged at the two sides of the front face of the ejection tool, and alignment positioning posts are arranged in the middle of the front face of the ejection tool. Chamfers capable of facilitating installation and leading-in are arranged at the tops of the ejection tool mandrils and the tops of the alignment positioning posts. The two ends of the ejection tool extend outwards to be provided with bosses which are convenient for hands to grab. Positioning tool positioning holes are formed in the two sides of the positioning tool and are used for positioning pins of the positioning tool and the injection mold. Positioning tool positioning grooves matched with magnetic steel are formed in the front face of the positioning tool and located in the positions corresponding to the ejection tool mandrils. The middle part of the positioning tool is provided with gluing positioning holes and an alignment post.

Description

technical field [0001] The invention relates to loudspeaker processing equipment, especially an injection molding device. [0002] The invention relates to a loudspeaker processing technology, in particular to an injection molding technology. Background technique [0003] With the continuous development of handheld electronic products, the requirements for the magnetic circuit structure of micro-speakers are getting higher and higher. How to realize the mass production of speakers with multiple magnetic steels during injection molding needs an urgent solution. The invention relates to the field of injection molding technology for multi-magnetic steel products, and mainly aims at the problems of low production efficiency, poor quality stability and high mold maintenance rate during injection molding of current multi-magnetic circuit micro-speakers. [0004] At present, the embedded injection molding of SPK magnetic steel mainly puts the required magnetic steel into the plast...
