Embodiment

[0047] see Figure 1 to Figure 10 , an integrated seamless structure foam earmuff manufacturing process in the embodiment of the present invention, comprising:

[0048] S1, providing the earmuff shell 102, foaming agent and foaming mold;

[0049] Specifically, the earmuff shell 102 may be in the form of a ring structure, which varies according to different types of earphones, and this embodiment does not limit the shape of the earmuff shell 102;

[0050] S2. Place the earmuff shell 102 in the cavity of the foaming mold, and leave a preset foaming space between the earmuff shell 102 and the inner side wall of the cavity;

[0051] S3, injecting the foaming agent into the mold cavity, placing the foaming agent in the foaming space;

[0052] S4. Clamping the foaming mold for a preset time, so that the foaming agent foams at a preset temperature;

[0053] S5. Open the foaming mold, and take out the finished product 1 of foaming earmuffs from the cavity of the foaming mold.

Abstract

The embodiment of the invention discloses a manufacturing process of a foaming earmuff of an integrated seamless structure, and is used for solving the technical problem that an earmuff of an existing headphone has a splicing seam. The process comprises the following steps that S1, an earmuff shell, a foaming agent and a foaming mold are provided; S2, the earmuff shell is placed in a cavity of the foaming mold, and a preset foaming space is reserved between the earmuff shell and the inner side wall of the cavity; S3, the foaming agent is injected into the cavity, and the foaming agent is placed in the foaming space; S4, the foaming mold is closed for a preset period of time, so that the foaming agent foams at a preset temperature; and S5, the foaming mold is opened, and a finished product of the foaming earmuff is taken out from the cavity of the foaming mold.

Description

technical field [0001] The invention relates to the technical field of earmuff design, in particular to a manufacturing process of an integral seamless structure foam earmuff. Background technique [0002] Existing headphones are generally composed of 5 parts, namely the head beam (belt), the driver, the connecting wire (there is no such part for wireless headphones), the ear shell (also called the cavity), and the ear pads. The assembly method is as follows: The headband is connected to the ear shells, the drivers are placed in the ear shells, and the ear pads are combined with the ear shells. Most of the ear shells are made of plastic materials, which are directly exposed as exterior structural parts (you can see them directly). Most of the ear pads are made of artificial synthetic leather or cloth or leather-wrapped sponge, which is also the appearance of the product and directly contacts the human ear, which requires high comfort. [0003] Such as Figure 11 As shown, ...
