There is provided a method for operating an injection molding apparatus (10) including a stationary mold (15), a movable mold (16) for cooperating with the stationary mold (15) to produce a molded product (35), an ejector pin (19) mounted within the movable mold (16), and a product removing arm (31) for taking out the molded product (35). The arm (31) starts to move towards a space (S) between the molds (15, 16) while the movable mold (16) is opened. During the movement of the arm (31), the pin (19) begins advancing to eject the product (35). The arm (31) holds the ejected product (35) within the space (S). The pin (19) is then retracted. The arm (31) holding the product (35) starts to move away from within the space (S) by the time the pin (19) completes the retracting operation.

L'invention concerne un procédé d'exploitation d'un dispositif de moulage par injection (10) comprenant un moule fixe (15), un moule mobile (16) destiné à coopérer avec le moule fixe (15), afin de donner lieu à un produit moulé (35), une tige d'éjection (19)montée dans le moule mobile (16) et un bras de retrait de produit (31) pour enlever le produit moulé (35). Le bras (31) commence à se déplacer vers un espace (S) situé entre les moules (15, 16), tandis que le moule mobile (16) est ouvert. Pendant le mouvement du bras (31), la tige (19) commence à avancer pour éjecter le produit (35). Le bras (31) maintient le produit éjecté (35) dans l'espace (S). La tige (19) est ensuite rentrée. Le bras (31) qui maintient le produit (35) commence à se déplacer et à sortir de l'espace (S) au moment où la broche (19) effectue de mouvement de retrait.
