Title (EN) MOLD INSERT AND METHOD OF MAKING A MOLD INSERT
(FR) INSERT DE MOULE ET PROCÉDÉ DE FABRICATION D'UN INSERT DE MOULE
Abstract:
(EN) The present application is concerned with a mold insert defining at least one filament cavity and having a stack of at least a first insert plate and a second insert plate, wherein the first plate has a front face that closely abuts a front face of the second insert plate, at least a portion of the at least one filament cavity is provided in at least one of the front faces of the first insert plate or second insert plate such that the filament cavity is open at a top surface of the mold insert but does not extend to a bottom surface of the mold insert, a venting cavity is provided in the same front face of the insert plate in which the portion of the at least one filament cavity is provided, which venting cavity is in air-conducting connection with the blind-hole end of the filament cavity, and the venting cavity has a depth in a direction essentially perpendicular to the front face of the respective first or second insert plate in which the venting cavity is provided that is the in the range of between 1 µm and 20 µm, in particular of between 2 µm and 10 µm. The present application is also concerned with a method of making such a mold insert and a mold machine comprising such a mold insert.
(FR) La présente invention concerne un insert de moule définissant au moins une cavité de filament et comprenant un empilement d'au moins une première plaque d'insert et une seconde plaque d'insert, la première plaque présentant une face avant qui s'appuie étroitement contre une face avant de la seconde plaque d'insert, au moins une partie de ladite cavité de filament étant disposée dans au moins l'une des faces avant de la première plaque d'insert ou de la seconde plaque d'insert de sorte que la cavité de filament est ouverte au niveau d'une surface supérieure de l'insert de moule mais ne s'étend pas vers une surface inférieure de l'insert de moule, une cavité de ventilation étant disposée dans la même face avant de la plaque d'insert dans laquelle la partie de ladite cavité de filament est prévue, ladite cavité de ventilation étant en liaison conductrice d'air avec l'extrémité de trou borgne de la cavité de filament, et la cavité de ventilation présentant une profondeur dans une direction sensiblement perpendiculaire à la face avant de la première ou de la seconde plaque d'insert respective dans laquelle la cavité de ventilation est comprise dans la plage de 1 µm à 20 µm, en particulier comprise entre 2 µm et 10 µm. La présente invention concerne également un procédé de fabrication d'un tel insert de moule et une machine de moulage comprenant un tel insert de moule.
