Silica gel acoustic part forming process

Abstract

The invention discloses a silica gel acoustic part forming process, and particularly relates to the technical field of silica gel. According to the technical scheme, the silica gel acoustic part forming process comprises a sound net offset detection device and a precise gel mixing and defoaming device, and further comprises the following specific technological processes that S1, liquid silica gel is put into an injection machine, and through the pressure of the injection machine, the silica gel is injected into a mold cavity at a set speed, and a mold is cooled through a water channel so as to cure the silica gel to obtain a product as same as the designed mold cavity; and S2, the sound net offset detection device is used, and a vibration disc module is used for automatically conveying silica gel. The silica gel acoustic part forming process has the beneficial effects that through hardware and sound net implanting, taking-out, material folding, inspection and hole dividing and disc arranging integrated automatic equipment, the original metal piece implanting, sound net implanting, mold closing, mold opening and inspection are changed into implanting, molding and inspection integration, and the blank of integrated molding inspection in the injection molding industry is filled.

Description

technical field [0001] The invention relates to the technical field of silica gel, in particular to a molding process of silica gel acoustic parts. Background technique [0002] Silica gel is polysiloxane rubber, polysiloxane used to be called silicone, the main chain structure is Si-O-Si structure, silicon atoms are connected through oxygen atoms, and at least one organic group is connected. It was invented by Eugene in 1940. Dr. RoChow made a major breakthrough in technology research and development. It is the earliest elemental polymer used in the industrial field. It has been widely used and developed due to its green and environmental protection characteristics. Since 1945, heat-vulcanized dimethyl silica gel has been effectively promoted. Mainly polydimethylsiloxane raw rubber is added with reinforcing agent and vulcanizing agent, and vulcanized into high-performance elastic silica gel after reaching the corresponding pressure and temperature. Later, room temperature v...

Problems solved by technology

[0005] For this reason, the present invention provides a molding process of silica gel-based acoustic parts, through the development of integrated automation equipment for hardware and sound net implantation, removal, material folding, inspection, and point placement, the original metal parts are implanted, the sound net is planted Inserting, mold closing, mold opening, and inspection are changed to integration of implantation molding inspection, which fills the blank of integrated molding inspection in the injection molding industry, and solves the problem that most of the products currently produced in China can basically meet the production needs of their customers. It will be very difficult for customers to require very high performance or special rubber types. There is a big gap in the domestic market for special silicone and high-performance rubber.
