Abstract

Improved extractor for tooling, designed to remove molds of great weight, which is characterized by being constituted by two identical telescopic columns, each of which is made up of two tubes of square section, displaying both, in their respective lower bases, some plates horizontally arranged laterally, which present, previously, a semicircular recess, while the upper tubes offer a head, inside each is located a truncated cone, which is provided at the end of a vertical screw with free rotation acting on a thread located in the lower tube that forms the telescopic column, the heads of rods are joined telescopic columns by a bar that has a longitudinal race, serving said guide bar to bring or separate both columns, in order to adapt their distance to the dimensions of the mold to be disassembled, having been foreseen in one of the ends of the menu the bar has a crank that allows a rotary movement to be printed on it, this turning effect on a pair of frustoconical pinions, which are mounted on the aforementioned bar with the possibility of longitudinal movement on it, rotating in unison because they are provided with keys that are located loosely in the longitudinal race mentioned above, the aforementioned pinions being arranged inside the heads of the telescopic columns, but in such a way that they mesh with the pinions belonging to the vertical screws, all with the purpose of introducing them in an adjacent superimposed position, the two plates of each telescopic column in the separation between the two bodies that make up the mold, covering the semicircular recess of the plates, the guide columns thereof, after which movement is printed to the rotating bar, thereby raising the moving upper body of the mold to the compass that the plates belonging s to the upper tubes of the telescopic columns.
