Claim 0:
1. A mixing device adapted for mixing a first material, a second material and a plurality of elastic fillers to form a molding material, said mixing device comprising:
a base including an upper case body, and a lower case body that is coupled to said upper case body and that cooperates with said upper case body to define an accommodating space, said upper case body having a first inlet and a second inlet that communicate with said accommodating space and that are adapted respectively for passage of the first and second materials into said accommodating space therethrough, said lower case body having a third inlet and an outlet that communicate with said accommodating space;
a side tube connected to said third inlet of said lower case body and cooperating with said third inlet for passage of the elastic fillers into said accommodating space therethrough;
a primary extruder screw disposed within said accommodating space and rotatable about a first axis;
a secondary extruder screw extending through said side tube, rotatable about a second axis that is transverse to the first axis, and adapted for conveying the elastic fillers into said accommodating space; and
a connecting rod disposed within said accommodating space and connected co-rotatable to said primary extruder screw, said accommodating space having a reaction zone that is located between said connecting rod and said lower case body of said base, that communicates with said first inlet and said second inlet of said upper case body of said base, and that is adapted for the first material and the second material to react therein;
wherein said primary extruder screw is operable for mixing the elastic fillers and a reaction product, which is made by reacting the first material and the second material, in said accommodating space to form the molding material, and extruding the molding material out of said accommodating space via said outlet;
wherein said connecting rod includes a connecting rod body connected to a top end of said primary extruder screw, and a plurality of protrusions protruding from said connecting rod body and adjacent to said reaction zone;
wherein said connecting rod body of said connecting rod extends along the first axis and has
a top section,
a bottom section under said top section, and
a connecting section connected between said top section and said bottom section;

wherein a cross-section of each of said top section and said bottom section perpendicular to the first axis is larger than that of said connecting section;
wherein said protrusions of said connecting rod protrude from said connecting section of said connecting rod body, said reaction zone of said accommodating space being defined among said protrusions, said connecting section and said lower case body; and
wherein said accommodating space further has
an upper channel defined cooperatively by said top section and said lower case body and communicating with said reaction zone, and
a lower channel defined cooperatively by said bottom section and said lower case body and communicating with said reaction zone.
