Abstract

Production of prototypes and soles for footwear involves placing two layers of silicone or rubber in a mold cavity, where an original or mock-up has been introduced between the parts. A negative is obtained, using temperature and pressure applied with the parts within a temperature-controlled heating chamber. The sole is then obtained by refilling with polyurethane or resin, using gravity or centrifugation.

Description

Procedimiento para la fabricación de prototipos y suelas para el calzado.Procedure for the manufacture of prototypes and Soles for footwear.

Objeto de la invenciónObject of the invention

La presente memoria descriptiva se refiere a una solicitud de una Patente de Invención, correspondiente a un procedimiento para la fabricación de prototipos y suelas para el calzado, cuya finalidad estriba en configurar una suela de calzado partiendo de moldes de silicona o caucho, utilizando un original o maqueta que determine por sí mismo la configuración del molde solicitado.The present specification refers to a application for an Invention Patent, corresponding to a procedure for the manufacture of prototypes and soles for footwear, whose purpose is to configure a sole of footwear starting from silicone or rubber molds, using an original or model that determines the mold configuration by itself requested.

Campo de la invenciónField of the Invention

Esta invención tiene su aplicación dentro de la industria dedicada a la fabricación de elementos y accesorios para la fabricación de calzado.This invention has its application within the industry dedicated to the manufacture of elements and accessories for shoe manufacturing

Antecedentes de la invenciónBackground of the invention

El solicitante conoce la existencia en la actualidad de una pluralidad de moldes para la fabricación de diferentes piezas, tal y como puede ser moldes de aluminio, las cuales tienen un elevado coste.The applicant knows the existence in the news of a plurality of molds for the manufacture of different pieces, such as aluminum molds, which have a high cost.

Cuando estos moldes se van a utilizar para la fabricación de un número reducido de piezas, su aplicación, aunque utilizada, presenta el inconveniente sustancial de su coste.When these molds are going to be used for manufacture of a small number of parts, their application, although used, presents the substantial inconvenience of its cost.

Consecuentemente sería deseable contar con un procedimiento para la fabricación de pequeñas tiradas o un reducido número de piezas para que empiece la fabricación óptima de las mismas, reduciendo sustancialmente el coste del molde.Consequently it would be desirable to have a procedure for the manufacture of small runs or a reduced number of parts to begin the optimal manufacturing of the themselves, substantially reducing the cost of the mold.

Sin embargo, por parte del solicitante actualmente no se tiene conocimiento de la existencia de un procedimiento que reúna las características citadas.However, by the applicant currently there is no knowledge of the existence of a procedure that meets the characteristics cited.

Descripción de la invenciónDescription of the invention

El procedimiento para la fabricación de prototipos y suelas para el calzado que la invención propone, presenta como característica fundamental la reducción de su coste.The procedure for manufacturing prototypes and soles for footwear that the invention proposes, presents as a fundamental characteristic the reduction of its cost.

De forma más concreta, el procedimiento para la fabricación de prototipos y suelas para el calzado objeto de la invención, está constituido a partir de la colocación del original o maqueta se coloca entre dos capas de silicona o caucho y esto a su vez dentro de un porta moldes y mediante un control del tiempo, presión y temperatura se obtiene por vulcanizado de las capas de silicona o caucho, el negativo dimanado del original o maqueta.More specifically, the procedure for manufacture of prototypes and soles for the footwear object of the invention, is constituted from the placement of the original or model is placed between two layers of silicone or rubber and this to in a mold holder and through time control, pressure and temperature is obtained by vulcanizing the layers of silicone or rubber, the negative stemming from the original or model.

Una vez efectuado el negativo, se retira el original o maqueta y se rellena el hueco existente entre las láminas o capas de silicona o caucho, por gravedad o centrifugación empleando poliuretano, resinas, etc.Once the negative has been made, the original or model and fill the gap between the silicone or rubber sheets or layers, by gravity or centrifugation using polyurethane, resins, etc.

Una vez terminada la operación de rellenado, se saca el positivo existente entre las láminas o capas de silicona o caucho, obteniéndose en realidad el objeto solicitado, que en este caso es una suela de calzado.Once the filling operation is finished, take out the positive between the sheets or layers of silicone or rubber, actually obtaining the requested object, which in this Case is a shoe sole.

Realización preferente de la invenciónPreferred Embodiment of the Invention

El procedimiento para la fabricación de prototipos y suelas para el calzado que se preconiza, se configura mediante la utilización de un original o maqueta, la cual se coloca entre dos láminas o capas de silicona o caucho y esto a su vez se sitúa en un porta moldes, que se introduce en el interior de una cámara (3) situada en la parte superior de una máquina (1) que presenta un cuerpo inferior (2) provisto de un cuadro de control (7), pulsador (6), elemento de seguridad (8), teniendo la cámara de calor (3), un portón (4), un asidero dentro del cual se encuentran situados las dos piezas(10) que medidas por un temporizador generarán presión y calor sobre el porta moldes que contiene las láminas o capas de silicona o caucho, entre las cuales se coloca el original o maqueta.The procedure for manufacturing prototypes and soles for the footwear that is recommended, is configured by using an original or mockup, which is placed between two sheets or layers of silicone or rubber and this in turn will placed in a mold holder, which is inserted inside a chamber (3) located on the top of a machine (1) that it has a lower body (2) provided with a control panel (7), push button (6), security element (8), having the camera heat (3), a gate (4), a handle within which they are located located the two pieces (10) that you measure by a timer will generate pressure and heat on the mold holder that contains the sheets or layers of silicone or rubber, between which the original or mockup.

Una vez que las capas de silicona o caucho situadas dentro del porta moldes han recibido el tiempo, presión y temperatura adecuadas dentro de las dos placas o piezas (10) se ha vulcanizado, se extraen de la cámara de calor (3) efectuando la apertura del portón (4) que se encuentra dotado de una bisagra (9) de retención, obteniéndose el original que posteriormente será utilizado para ser rellenado por gravedad, centrifugación o similar empleándose como material de relleno poliuretano, resinas, etc.Once the silicone or rubber layers located inside the mold holder have received the time, pressure and suitable temperature inside the two plates or pieces (10) has Vulcanized, they are removed from the heat chamber (3) by performing the gate opening (4) which is equipped with a hinge (9) of retention, obtaining the original that will later be used to be filled by gravity, centrifugation or similar being used as filling material polyurethane, resins, etc.

Cuando el proceso se concluye, se extrae el positivo existente entre las capas de silicona o caucho, constitutivas del molde, previamente tratada, obteniéndose la suela del calzado solicitada.When the process is completed, the positive between the layers of silicone or rubber, constitutive of the mold, previously treated, obtaining the sole of the requested footwear.
