Production process of foaming headset sleeve

Abstract

The invention discloses a production process of a foaming headset sleeve, and the production process comprises the following steps of a, preparation of materials: placing a well mixed material A and a well mixed material B respectively into a mixing kettle to be stirred; b, mixing: simultaneously placing the material A and the material B into the mixing kettle to be adequately stirred and mixed to form a mixed material; c, injection: continuously injecting the mixed material into a plurality of molds which are matched with each headset sleeve in shape through a mixing reaction kettle, arranging the molds in a single row in the transverse direction, and realizing automatic circular work through a transmission device; d, baking: automatically feeding the molds with the mixed material into a baking box to be baked through the transmission device; and e, demolding: pouring out the headset sleeves from the molds through the transmission device so as to enable the headset sleeves to be separated from the molds after baking is completed. Compared with the prior art, the production process of the foaming headset sleeve has the advantages of simplicity in production equipment, few in manufacturing procedures, simplicity in mold structure, long in service life, capability of being formed in one step, good forming quality, low production cost and low energy consumption.

Description

technical field [0001] The invention relates to the technical field of earphone manufacturing, in particular to a production process of a foam earphone cover. Background technique [0002] Users of phones, audio and video players, and other mobile devices are increasingly choosing headsets for convenience, privacy, and more. There are various forms of earphones. According to their energy conversion methods, there are mainly moving coil, moving iron, electrostatic and electromagnetic types; from the separation method, they can be divided into semi-open type and closed type; from the wearing form The upper classification includes earplugs, hanging ears, in-ears and head-mounted. Generally, earplugs and in-ears are widely used because of their relatively small structures. [0003] Both earbuds and in-ear headphones have a portion sized to be inserted at least partially into the ear canal, and while these headphones may provide better performance in some situations, they may be...

Problems solved by technology

[0013] 1. The structure of the earphone cover forming mold is complicated, the manufacturing is difficult, and the mold cost is high;

[0014] 2. Due to the large size of the forming mold, the baking oven is also set up relatively large, resulting in an increase in the cost of the oven. At the same time, because the forming mold is set on the rotary table, this will cause the baking area of ​​the oven to be inaccessible. Make full use of it, so that the energy consumption of the oven is large, the loss is relatively large, and it cannot meet the energy-saving and emission-reduction plan required by the state;

[0015] 3. There are several mold holes on the forming mold, and the finished products are easy to connect together during manufacture, so it needs to be divided by a sponge cutting machine, which will easily cause the earphone sets to become defective or waste products, which will reduce the production pass rate , and also increased the subsequent process of sorting qualified products, which further increased the manufacturing cost;

[0016] 4. The cost of the earphone cover produced according to this production method is high. Taking the hollow conical foam earphone cover of φ8 / φ12×15mm and the thickness of 2mm as an example, the approximate cost of producing one earphone cover is one yuan. It will increase the cost of the whole earphone and affect the follow-up earphone sales
