Description

Hydraulic silica gel two-component injection machine Technical Field The invention relates to the technical field of injection machines, in particular to a hydraulic silica gel double-component injection machine. Background The core of the two-component liquid silica gel injection molding technology is that A, B liquid components are mixed according to an accurate proportion and are thermally cured and molded in a mold, wherein the accuracy of the mixing proportion and the removal of bubbles in materials directly determine the mechanical property, appearance quality and qualification rate of the product, so that strict requirements are put on the metering stability and degassing capability of an injection machine. The typical hydraulic silica gel double-component injection machine at present generally adopts the following operation flow, wherein A, B components are respectively stored in independent charging barrels, initial exhaust is carried out through a manual pressure plate type feeding system, an operator presses a pressure plate and observes an exhaust hole, a valve is closed at the moment of overflow of glue solution by experience to remove air in the barrels, then materials are metered through a plunger or a gear pump driven by hydraulic pressure and conveyed into a static mixer to be mixed, and finally mixed glue stock is injected into a die through a hydraulic injection unit. In the process, the exhausting, metering and mixing links are carried out in a sectionalized way independently, and manual intervention and time control are relied on.
