Abstract

The invention relates to the technical field of dies, in particular to an injection mold for a horn vibrating membrane, comprising a front die and a rear die used in match with the front die, wherein a sprue is formed in the front die, the rear die is provided with a die core used for forming a liquid silicone layer, the front die is provided with an insert, at a position right facing to the die core, and in die assembly, the insert props against the die core; and a silicone incoming runner and a silicone outgoing runner for liquid silicone to flow are arranged between the front die and the rear die, the silicone incoming runner comprises a main silicone incoming runner and a bevel silicone incoming runner which communicate with each other, the silicone outgoing runner comprises a bevel silicone outgoing runner and a main silicone outgoing runner which communicate with each other, each die core is provided with a silicone incoming hole and a silicone outgoing hole, the silicone outlet of the bevel silicone incoming runner communicates with the silicone inlet of the die core, and the silicone outlet of the die core communicates with the silicone inlet of the bevel silicone outgoing runner. The injection mold for a horn vibrating membrane is simple in structure, simple in process, and high in processing efficiency, and can effectively save manpower resource, and the tone quality of a produced horn vibrating membrane is good.

Description

technical field [0001] The invention relates to the field of diaphragm technology, in particular to a horn diaphragm injection mold. Background technique [0002] At present, the traditional production mode is adopted for plastic speakers, which require materials: basin plastic molds, ABS raw materials, T iron, ring magnets, washers; required accessories: AB glue, magnetic return positioning gauge; required equipment: AB magnetic return glue machine , Injection molding machine; required personnel: 4 people; when working, first inject the ABS raw material through the injection molding machine to inject the speaker basin frame, and then combine the washer and the speaker basin frame by glue, screw riveting or injection molding with the injection molding machine, and then AB The operator of the melter puts AB glue on the side of the ring magnet and the T iron, and the next operator combines the ring magnet with the AB glue and the T iron; the next operator combines the ring mag...
