Description

Injection molding clamp

Technical Field

The application relates to the technical field of injection molding, in particular to an injection molding clamp for manufacturing a liquid-cooled light module.

Background

The liquid cold light module has wide application prospect in the fields of data centers, cloud computing and the like. With the rapid development of these fields, the need for liquid-cooled modules is also increasing.

The liquid cold light module is an emerging light module technology, and adopts liquid as a heat transfer medium, so that the heat dissipation efficiency of the light module can be effectively improved. The low pressure injection molding technique is an important process means for manufacturing the liquid-cooled light module, so as to protect the optical elements of the light module from the cooling liquid.

The prior glue injection process for manufacturing the liquid cooling optical module mainly comprises the steps of melting a hot melt glue rod into glue materials through a hot melt glue gun and a glue injection clamp, and injecting the glue materials into a cavity of an outer shell of the optical module to form a glue block so as to achieve the purpose of wrapping and protecting a printed circuit board and related devices. However, the operation strength of the manufacturing process workers is high, and the working efficiency is low; in addition, due to limited manual glue injection pressure, the glue block can be wrapped and insufficient in airtightness, so that the liquid cooling medium is invaded into the optical module device to cause failure.
