To extend the useful life of the elastic seal (6) which is arranged between a base plate (1) and a cover plate (2) of molds for the production of flat moldings of curable casting resins and through the passages (8) of which the mold cavity is charged with the casting resin melt and vented and to accelerate venting and filling, the passages (8) are in the form of fixed capillary tubes (9) which project partly into the seal (6) and which are each adjoined by a channel (10) opening into the mold cavity (3) and closure needles (13) insertable into the channels are provided.

Mold for the production of flat moldings of curable casting resins

A pacified mass is hardened under controlled conditions to produce low tension moulded parts (4) of duroplasts, the shringkage being compensated for by the movement of a lower mould part (2) and/or an upper mould part (3) to follow the mass.
