Abstract:
1. A mold oscillating apparatus, comprising: a mold table for supporting a mold; a base frame for supporting said mold table on the upper side or the lower side thereof, and an oscillation mechanism for oscillating said mold table, the oscillation mechanism being arranged between said base frame and said mold table, the oscillation mechanism comprising: drive means; a stationary bearing housing interconnected to said base frame; a moving bearing housing interconnected to said mold table; oscillation generating means provided with a shaft interconnected to said drive means, said shaft having a shaft portion supported by said stationary bearing housing and an eccentric shaft portion supported by said moving bearing housing; oscillation direction regulating means for regulating lateral displacement and accepting up and down displacement, in oscillation of said mold table generated by said oscillation generating means; and a connecting plate arranged between said moving bearing housing and said mold table, the connecting plate extending in the axial direction of said shaft, being supported by said mold table from one end of an end part opposing to said mold table to the other end, and being supported by said moving bearing housing from one end of an end part opposing to said moving bearing housing, wherein said connecting plate absorbs the lateral displacement regulated by said oscillation direction regulating means with elastic deformation.
