Abstract
An instant-release type concrete molding machine manufactures a concrete product by interposing unitable attachment devices between a press die and a press, placing an attachment unit of a pattern frame within a molding region, introducing the pattern frame and the press die into the molding region in alignment with the press, moving the press and the press die toward each other and uniting them by the aforementioned attachment devices, and fixing the pattern frame by the attachment unit within the molding region.
Claims20
A method for setting a pattern frame and a press die within a molding machine, comprising the steps of:
- providing a molding region within said molding machine;
- providing a pattern frame having a mold cavity defined therein;
- providing pattern frame retaining means within said molding region of said molding machine for retaining said pattern frame within said molding region of said molding machine;
- providing a hopper means for holding concrete material to be molded within said mold cavity of said pattern frame;
- providing a reciprocating material supply box movable between said hopper means and said mold cavity of said pattern frame so as to supply said concrete material from said hopper means to said mold cavity of said pattern frame retained within said molding region of said molding machine;
- providing a reciprocating press within said molding region of said molding machine;
- providing a press die to be mounted upon said reciprocating press so as to compress said concrete material to be molded within said mold cavity of said pattern frame;
- providing first attachment means upon said reciprocating press, and second attachment means upon said press die, for mating with each other so as to secure said press die upon said reciprocating press;
- mating said press die within said pattern frame at a position outside of said molding region;
- transferring said mated press die and said pattern frame as a modular unit from said position outside of said molding region and into said molding region so as to cause engagement of said pattern frame with said pattern frame retaining means as said press die-pattern frame modular unit is transferred from said position outside of said molding region and into said molding region whereby said pattern frame will be retained within said molding region by said pattern frame retaining means;
- and
- causing relative movement between said press die and said reciprocating press so as to mate said first and second attachment means of said reciprocating press and said press die whereby said press die will be secured upon said reciprocating press.

Apparatus for setting a pattern frame and a press die within a molding machine, said apparatus comprising:
- means defining a molding region within said molding machine;
- a pattern frame defining a mold cavity therein;
- pattern frame retaining means disposed within said molding region of said molding machine for retaining said pattern frame within said molding region of said molding machine;
- means defined upon said pattern frame for engaging said pattern frame retaining means whereby said pattern frame is retained within said molding region of said molding machine;
- hopper means for holding concrete material to be molded within said mold cavity of said pattern frame;
- a reciprocating material supply box movable between said hopper means and said mold cavity of said pattern frame for supplying said concrete material from said hopper to said mold cavity of said pattern frame;
- a reciprocating press disposed within said molding region of said molding machine;
- a press die to be mounted upon said reciprocating press so as to compress said concrete material to be molded within said mold cavity of said pattern frame;
- first attachment means mounted upon said reciprocating press, and second attachment means mounted upon said press die, for mating engagement with each other so as to secure said press die upon said press;
- means for transferring said press die and said pattern frame as a modular unit from a position outside of said molding region into said molding region so as to cause engagement of said pattern frame engaging means with said pattern frame retaining means as said press die-pattern frame modular unit is transferred from said position outside of said molding region and into said molding region whereby said pattern frame will be retained within said molding region by said pattern frame retaining means;
- and
- means for causing relative movement between said press and said press die so as to cause said mating engagement of said first and second attachment means of said reciprocating press and said press die, respectively.
