Definitions

  • the present invention relates to a device for die-cutting and ejecting elastomer stoppers comprising: - a cutting matrix, - a series of punches facing the cavities of the matrix and fastened to a punch holder plate assembled in an upper cutting cross member, with the possibility of vertical movement, and - means for ejecting the stoppers retained in the matrix.
  • This invention is applicable to the field dedicated to the manufacture of elastomer stoppers and has technical characteristics that enable the stoppers to be mechanically ejected and ejecting means to be manually disassembled and replaced in order to adapt them to different formats of the product to be manufactured.
  • Devices used for manufacturing stoppers by die-cutting an elastomer strip that is arranged on a cutting matrix and comprising vertically movable punches and which carry out the die-cutting of the elastomer band when introduced into cavities of the matrix are currently known.
  • the technical problem that is proposed is the development of a device for die-cutting and ejecting elastomer stoppers that ensures the complete ejection of the stoppers and that can be easily adapted to change the format of the product.
  • the device for die-cutting and ejecting elastomer stoppers object of this invention has technical characteristics intended to solve the aforementioned problem; specifically: on one hand, to ensure the ejection of the stoppers, and on the other hand, to quickly change the format of the product.
  • this device comprises means for mechanically extracting the stoppers, consisting of ejectors that pass through the entire cutting system and push the stoppers until freeing them from the lower cutting matrix or tool.
  • ejectors are fastened to an ejector holder plate connected to an actuating cylinder by means of a ball joint fastened to a ball joint extension by means of a detachable flange; enabling said detachable flange to quickly change the format of the product to be manufactured, manually replacing the ejector holder plate.
  • This mechanical ejection ensures that the material is ejected until the end, ensuring that no stopper or any residue from prior production remains housed inside the tool.
  • this device comprises an ejector holder plate (1) wherein the ejectors (2) that pass through an intermediate plate (3) and the punches (4) mounted on a punch holder plate (41) are fastened and which are arranged facing the cavities of a matrix (5) mounted on a matrix holder plate (6).
  • This device comprises an upper cutting cross member (7) on which a support plate (9) of actuating cylinders (10) is assembled by means of supports (8).
  • the cylinder (10) that occupies the central position in the figure is the one responsible for moving the ejector holder plate (2) and is connected to said ejector holder (2) by means of a ball joint (11) and a ball joint extension (12) fastened to said ball joint (11) by means of a detachable flange (13) that enables the disconnection thereof in order to manually replace the ejector holder plate (1) as shown in Figure 2 and to change the format of the product.
