Abstract
A mold apparatus which in addition to the other mold elements, has shuttle plate means adjacent to the nozzle means out of which the molding composition comes out of into the mold cavity, which shuttle plate means forms part of the mold cavity. The shuttle plate means are adapted to automatically take a finished molded part from the mold and remove it out of the mold apparatus. At the same time while the molded part is being taken out of one portion of the shuttle plate means, the other part of the shuttle plate means is being utilized to form a molded part.
Claims18
A mold apparatus for a liquid injection molding apparatus for forming parts from a liquid molding composition comprising:
- a frame having a forward end and a rear end;
- mold plate means mounted on said frame and having a front end and a rear end;
- support means mounted on said mold plate means and having a front end and support post at the rear end;
- a conduit for liquid molding composition slidably mounted on the forward end of said frame and on the forward end of said mold frame means;
- a first plate means having passage means therein for the passage of liquid molding composition and fixedly mounted on the end of said conduit and adapted to slide within said support post means and within mold frame means and located adjacent said forward end of said frame;
- nozzle means located at the end of said passage means in said first plate means adjacent the rear end of said mold frame means away from said conduit means, said nozzle means including closing pin means slidably mounted in said mold frame means and adapted to open and close a nozzle opening means in said nozzle means;
- shuttle plate means adjacent to said nozzle means which forms part of the mold cavity, said shuttle plate means adapted to automatically take a finished molded part from the mold and pass it out of the mold apparatus by providing a knock-out plate means located on both sides of said nozzle means, in the same plane as said nozzle means and substantially external to the support post means, said knock-out plate means being integral with the nozzle plate and comprising first and second knock-out plates containing knock-out pins which are adapted to fit in the mold cavities in said moving shuttle plate means so as to knock out the molded parts in the mold cavities in said moving shuttle plate means;
- and
- mold cavity means slidably mounted on the rear end of said support part means and adapted to move toward and away from said shuttle plate means.
