Definitions

  • the present invention refers to a process for manufacturing polyurethane foam pieces with textile coating and mold for obtaining them.
  • the mold is then opened by removing the cover to extract the manufactured part with the inclusion of the textile laminar body attached to the polyurethane material by a surface part thereof previously provided.
  • the object of the invention is a new method in which a main portion of the textile laminar body is attached against a front surface of a movable part of the mold, the rest of that textile laminar body remaining outside the interior space of the mold.
  • foaming on open mold of polyurethane foam is well known, subsequently closing it for the geometric conformation and adaptation of the foam to the interior configuration of the mold.
  • the normally aluminum mold is composed of a bottom and its corresponding cover or covers, which together configure the geometry that is to be achieved, the whole assembly being normally heated.
  • the process is the following.
  • liquid polyurethane is poured into the bottom thereof, so that when the polyurethane reacts in contact with the air and supported with the temperature of the mold, such polyurethane material begins to grow, increasing its volume, closing the lid or mold caps, whereby the polyurethane adapts to the internal geometry of the mold.
  • the polyurethane cures and solidifies, and then once the mold is opened, remove the manufactured part. This piece thus obtained is subsequently covered with a textile sheath.
  • This manufacturing process would be as follows.
  • the textile cover is placed and adapted, by vacuum aspiration, to then pour the liquid polyurethane onto the textile.
  • the necessary covers are closed and the polyurethane grows and adapts by taking the mold geometry and in turn firmly joining the textile material placed on the mold walls. The result is a piece of polyurethane foam with the textile cover attached to it.
  • the invention consists in a process for manufacturing polyurethane foam pieces with textile coating and mold for obtaining them.
  • the process aims to obtain a piece of polyurethane foam, a part of which requires to be attached to a textile laminar body, without interposing barriers between the foam piece to be obtained and some parts of the textile laminar body, so that the new invention allows take advantage of the facilities and advantages of traditional formulations.
  • the tooling of the open mold developed adapts to the current foaming facilities, without these having to be modified and being able to coexist in the manufacture with traditional foaming molds.
  • the novelty presented is that starting from a traditional foaming mold, it is modified to be able to perform in some areas of it a "foaming in situ", without these affecting the normal operation of the installation.
  • the area where it is intended to foam on top of the cover must be independent of the rest, at least in functionality, during a series of steps in the process; to then fit the rest of the mold and form a unit with it.
  • this area of the mold must have some system to fix and adapt a textile laminar body determining a cover to the corresponding surface, such as a vacuum suction system.
  • an open mold whose area where the cover is foam, has movement, either with linear displacement or angular displacement, to be able to separate it from the rest of the mold.
  • This area is equipped with a double wall and small holes in the surface, to be able to perform the vacuum by vacuum.
  • the aim of the movement is to be able to protect under it the parts of the case that are not going to be over-foamed.

  • That false frame 12 can have linear or angular movement to move from an inactive position to an active one and vice versa, the active position corresponding to the preparation of the open mold 1 'to receive the polyurethane material.

Abstract

L'invention concerne un procédé dans lequel des pièces de polyuréthanne à revêtement textile sont fabriquées au moyen d'un moule ouvert. Le procédé est caractérisé en ce que, pendant une étape initiale, préalablement au versement du polyuréthanne liquide à l'intérieur du moule ouvert, une partie principale (4) d'un corps laminaire textile (5) recouvre une surface frontale (3) du fond du moule ouvert (1), une surface frontale (3) étant incorporée dans une partie mobile (2) du moule ouvert (1), ladite partie mobile (2) étant pendant l'étape initiale déplacée par rapport au reste du moule ouvert (1). En revanche, pendant une étape postérieure, la partie mobile (2) est déplacée pour être placée dans une position définitive par rapport au reste du moule ouvert (1) pour procéder par la suite au versement du polyuréthanne liquide, le reste du corps laminaire textile (5) étant situé hors de l'espace intérieur du moule ouvert (1).
