Abstract:
A directly controlled hydraulic press with a molding equipment capable of holding at least two molds set side by side, comprising:a fixed support; two or more first half molds held by the fixed support and set side by side; a mobile support having a lower surface and an upper surface and capable of movement toward and away from the fixed support; two or more second half molds held by the upper surface of the mobile support and set side by side; at least one power cylinder interposed between every first half mold and the fixed support, which allows to fine-tune the closing of the molds, thus compensating for any differences in the height of the two molds; and a plurality of devices for impeding reverse motion of the mobile support during the closing of the molds, each of the plurality of devices comprising a pair of pushing pins movable between two positions, a first position in which a free end of each pin is in contact with the upper surface of the mobile support to impede reverse motion of the mobile support and a second position in which the free end of each pin extends beyond the extremities of the upper surface of the mobile support; wherein each of the plurality of devices further comprises guide means in which the end of each pushing pin opposite the free end is movably positioned, the guide means being inclined to the vertical to permit movement of the free ends of the pushing pins beyond the extremities of the upper surface of the mobile support.
