Ear handle outer mold injection molding module

Abstract

The invention discloses an ear handle external mold injection molding module. The injection molding module comprises an injection molding bottom mold, an injection molding lower mold and an injectionmolding upper mold, wherein a first ear handle forming cavity and first position avoiding wire grooves are formed in the injection molding bottom mold, and the first ear handle forming cavity is in communication with the first avoiding wire grooves; the injection molding lower mold is provided with a wire containing half groove and second position avoiding wire grooves, and the wire containing half groove is in communication with the second position avoiding wire grooves; the injection molding upper mold is provided with a second ear handle forming cavity and third position avoiding wire grooves, and the second ear handle forming cavity is in communication with the third position avoiding wire grooves; when the injection molding lower mold is used for covering the injection molding bottommold, the first ear handle forming cavity is enabled to be in communication with the wire containing half groove; and when the injection molding upper mold is used for covering the injection molding bottom mold, the first ear handle forming cavity is enabled to be in communication with the second ear handle forming cavity. According to the injection molding module, one injection mold can be saved,and the cost of injection molding can be reduced. The situation of incomplete injection molding can also be avoided, so that the quality of the earphone wire can be improved, and the production efficiency of the ear handle injection molding is further improved.

Description

technical field [0001] The invention relates to the field of injection molding structures of earphones, in particular to an injection molding module for an outer mold of an ear handle. Background technique [0002] There are ear shells and ear handles on the earphones. The ear handles are clipped on the ear shells to protect the earphone wires. The ear shells are used as in-ear earphone components to be placed on the ears, and the ear shells A loudspeaker structure is arranged inside, so that music can be played after the ear shell is placed in the ear, realizing the function of the earphone. [0003] In the traditional injection molding method of ear handles of earphones, there are two sets of molds, and each set of molds includes an upper mold and a lower mold. When injection molding is performed, the earphone wire is placed on the lower mold of the first set of molds. , and then place the corresponding upper mold on the lower mold to inject glue, so that the lower half o...

Problems solved by technology

[0004] However, the traditional ear handle injection mold uses two sets of molds for injection molding. After one is injected, the earphone wire must be removed and placed on another mold for injection molding, which will greatly reduce the injection molding efficiency of the earphone wire; and, When replacing the injection mold, the ear handle of the lower half of the injection molded part must be accurately embedded in the groove of the upper mold of the second set of molds, so that the ear handle of the earphone can be completely injected. If it is placed in the groove of the upper mold, the ear handle after injection molding will not completely cover the earphone wire, and the earphone wire may also be pressed by the upper mold, resulting in low quality of the earphone wire and reducing the ear handle of the earphone. Quality, which further leads to inefficient injection molding of earphone wires
