초록 ▼

A housing is formed with a quieting chamber which opens in one direction into a mold and with a mixing chamber opening in another direction at right angles to the first-mentioned direction into the quieting chamber. A pair of reactive components are introduced into the mixing chamber to form a mixture therein. Thereupon a mixing piston or plunger is shifted along this mixing chamber at right angles to the quieting chamber so as to force the mixture out of the mixing chamber and into the quiescence chamber. This piston at the end of its stroke lies with is end face flush and contiguous with a planar inner surface of the quieting chamber. Thereupon a displacement piston or plunger moves the full length of the quieting chamber so as to press the mixture from this chamber into the mold. The quieting chamber has the cross-sectional shape of a circular segment and the mixing chamber is of uniform circular cross-section.

An apparatus for charging a mold with a mixture of at least two interreactive components, said apparatus comprising an elongated quieting chamber opening into said mold at a wall of a mold cavity, an elongated mixing chamber extending at right angles to said quieting chamber and opening into the latter at a wall of said quieting chamber, and valve means operatively associated with said mixing chamber fOr controlling the flow of said components into said mixing chamber, the improvement wherein said apparatus further comprises: said quieting chamber having a cross-sectional area equal to that of said mixing chamber and a width greater than that of the inlet opening into it from said mixing chamber, a plunger reciprocable in said quieting chamber and of a cross section complementary thereto for completely driving the mixture from said quieting chamber into said mold cavity; and abutment means engageable by said plunger for halting advance thereof with an end face of said plunger flush with said wall of said mold cavity, said valve means including a second plunger reciprocable in said mixing chamber at right angles to the first-mentioned plunger and of a cross section complementary to that of said mixing chamber for completely driving the mixture from said mixing chamber into said quieting chamber; and second abutment means engageable with said second plunger for halting the advance thereof with an end face of said second plunger flush with said wall of said chamber, each of said plungers being provided at an end remote from its end face with a piston, said apparatus further comprising respective cylinders receiving said pistons and means for pressurizing said cylinders to displace said pistons, said end face of said second piston being planar and perpendicular to the direction of displacement thereof, said wall of said quieting chamber being planar and parallel to said end face of said second piston, said first piston being formed with a flat sliding along said wall of said quieting chamber, said mixing chamber being formed with a respective pair of ports assigned to each of said components and longitudinally spaced apart in the direction of reciprocation of said second piston, means for supplying the respective component to the port of each pair proximal to the quieting chamber and for collecting the respective component from the port of each pair distal from the quieting chamber, and said second plunger being provided with respective longitudinally extending passages connecting the ports of each pair in a position of the second plunger in which its end face lies flush with said wall of said quieting chamber.
