Injection-molded mobile phone sound cavity structure assembly

Abstract

The invention discloses an injection-molded mobile phone sound cavity structure assembly. Ultrasonic wire grooves are formed in the edges of the front face and the back face of a first plastic body, hardware fixing holes are formed in the two ends of a first hardware body, a sound outlet hole is formed in one end of the side face of the first plastic body, and a first plastic injection port is formed in the other end of the side face of the first plastic body. A second wire fixing hole is formed in the middle of the back surface of a middle shell, a first ultrasonic boss is arranged around theedge of the middle shell, and a third plastic injection port is formed in the side surface of the middle shell. A lower shell comprises a second plastic body, a second hardware body located on the left side of the second plastic body and a third hardware body located on the right side of the second plastic body. An upper shell, the middle shell and the lower shell are developed together, adverseconditions in the product production and manufacturing process are improved, a positioning material belt is used for positioning during injection molding, accurate positioning of stamping accessoriesis effectively guaranteed, the product quality is improved, and the cost is reduced. Parts formed through injection molding are stable, product functions are improved and optimized, and the service life of the parts is prolonged.

Description

technical field [0001] The invention relates to the technical equipment field of mobile phone frame accessories, in particular to an injection-molded mobile phone sound cavity structural component. Background technique [0002] With the rapid development of 5G, the replacement of mobile phones is getting faster and faster, and the requirements for the development and production of mobile phone accessories are also increasing. Whether it is the use of space, or the waterproof effect, the improvement of signal transmission has also raised new challenges for product development and manufacturers. higher requirement. In terms of design and production, not only stay in the development of a single product, but produce combined parts, so that many problems in the product assembly process can be found and reduced, and more can be realized in the product design and manufacturing process. Taking into account and meeting the needs of customers, and improving market competitiveness thr...
