    Device for the demolding of parts and mold comprising said device. The device for demolding pieces comprises a slide (11) to receive a figure insert (12) for molding a negative (13) of the piece to be molded, said slide (11) being associated with a push rod ( 7), which can move said slide (11) to a position of ejection of a piece to be molded, and is characterized in that it comprises a gas cylinder (1) to drive the displacement of said push rod (7). It allows to eliminate the inclined guide and the wedge of security, saving a big amount of work and focus all the mechanized, only in the punch plate.

    Gas cylinder 1 is in the extended position, the slide 11 is in the release position of the plastic part (Figure 3b). When the gas cylinder 1 passes from its retracted position to its extended position, the slide retracts or moves to the left, according to the arrangement shown in Figure 2.
    5 The distal end of the rod preferably contacts the push bar 7 by means of a stop 2, fixed to one of the ends of the push bar 7.
    At the other end, said push bar 7 preferably comprises an adjustment disc 10 8, to easily adjust the length of the push bar 7 very precisely.
    Said push bar 7 comprises at its upper end a rack 21, which meshes with another rack 22 of said slide 11, the movement of said push bar 7 being transferred to said slide 11 through said zippers 21, 22.
    15 As can be seen in the figures, the rack 22 of the slide 11 is positioned with its teeth inclined with respect to the longitudinal axis of the slide 11, and the teeth of the drive rack 21 of the push bar 7 are also positioned inclined with respect to to the longitudinal axis of the push bar 7.
    20 It should be noted that the inclination of these teeth is variable, so that the inclination of the slide 11 can be varied with respect to the push bar 7 in a very simple manner, thus increasing or decreasing the demoulding path.
    If desired, the demoulding device according to the present invention may also comprise refrigeration, in particular a cooling source 5 provided with a tube 3 for the passage of cooling water, cooling the insert 12 and / or the cylinder gas 1 and, consequently, the negative 13. This cooling source 5 is rotatable, allowing the positioning of said cooling source 5.
    Although reference has been made to a specific embodiment of the invention, it is apparent to one skilled in the art that the mold release device and mold described are susceptible of numerous variations and modifications, and that all the mentioned details may be replaced by other technically equivalent ones, without
    35 depart from the scope of protection defined by the appended claims.
