Estimating the term…
The sealant injector for molding a display frame is provided for extruding the sealant out of the cavity, the large impurity particles could be insulated from the filtrating holes for preventing the mixing particles or the air bubble forcing out from the spray nozzle. The extrusion sealant could be more uniform. The sealant could be coated on the base board with the filtering and forcing. Accordingly, it would increase the continuation, the stability, the strength and the tenacity of the sealant and then improve the rate of good products. On the process of filtering and extruding together, it could reduce the molding time and improve the manufacture efficiency. The present invention also provides a method for injection molding a display frame using the sealant injector.
A sealant injector for molding a display frame, comprising a cavity, an opening being opened on the top of the cavity for connecting with the high pressure nitrogen, and a spray nozzle located at the bottom of the cavity, the sealant filling in the cavity being extruded from the spray nozzle, wherein a filtrating equipment is located in the cavity for insulating a plurality of larger impurity particles mixing with the sealant.
A method for injection molding a display frame using the sealant injector, comprising the following steps:
