Molde para fabricar suelas para calzado y método de fabricación.Mold to manufacture soles for footwear and method of manufacturing.
La presente invención, según lo expresa el enunciado de esta memoria descriptiva, se refiere a un molde para fabricar suelas para calzado y método de fabricación, con los que se alcanzan notables ventajas para este sector de la técnica.The present invention, as expressed by the set forth in this specification, refers to a template for manufacture soles for footwear and manufacturing method, with which Remarkable advantages for this sector of the technique.
Hay una gran demanda de suelas de goma bicolor del tipo constituido por una bandeleta perimetral unida a una plancha de base o piso que suele tener un grosor igual o poco diferente por toda su geometría. La bandeleta y la plancha de base suelen tener diferente color, de ahí el nombre bicolor, aunque puede ser también monocolor.There is a great demand for bicolor rubber soles of the type constituted by a perimeter shelf joined to a base plate or floor that usually has an equal or little thickness different for all its geometry. The tray and the base plate they usually have different color, hence the bicolor name, although it can Be also single color.
Es un objeto de la invención, poder incorporar tiras de otro color en la bandeleta, así como proporcionar un sistema de desmoldeo fácil.It is an object of the invention, to incorporate other color strips on the tray, as well as providing a easy release system.
En la actualidad se consigue la fabricación de este tipo de suelas con bandeleta, mediante un molde de tres piezas, como veremos claramente en relación con las figuras. En la pieza superior o tapa se forma el hueco que será ocupado por la goma de la bandeleta, introducida entre la pared de dicho hueco y un macho postizo emergente del fondo del mismo. El piso de la suela se obtiene independientemente, aunque en la misma fase de moldeo, con la pieza inferior o base dotada de un rebaje o rehundido en su cara superior. El molde se cierra interponiendo entre estas dos piezas, la pieza intermedia que sella así las dos cámaras portadoras de la goma.Currently, the manufacture of this type of soles with bandeleta, by means of a mold of three pieces, as we will see clearly in relation to the figures. In the room upper or cover is formed the hole that will be occupied by the rubber of the bandeleta, inserted between the wall of said hole and a male pop-up of the bottom of it. The sole floor is obtained independently, although in the same molding phase, with the lower part or base endowed with a recess or recessed in its face higher. The mold is closed by interposing between these two pieces, the intermediate piece that seals the two carrier chambers of the rubber.
La construcción de este tipo de suelas era típica de obtener en "autoclave" donde a la bandeleta se le añadían unas tiras horizontales y paralelas en los laterales y de otro color que podía o no coincidir con el del piso.The construction of this type of soles was typical of obtaining in "autoclave" where the bandeleta is they added horizontal and parallel strips on the sides and another color that may or may not match that of the floor.
En la demanda actual de este tipo de calzado, se exigen tiras de color en la bandeleta, así como incluso en el cerco superior de la misma. El método "autoclave" prácticamente ha desaparecido y con los moldes convencionales de bicolor no se puede hacer la incorporación de tiras de otro color por resultar imposible acceder al lugar en que hay que colocarlas en la oquedad de la tapa, debido a la inevitable presencia del macho postizo que configura el interior o casco del piso de la suela.In the current demand for this type of footwear, they demand colored strips on the tray, as well as even on the fence top of it. The "autoclave" method has practically disappeared and with conventional bicolor molds you can't make the incorporation of strips of another color because it is impossible access the place where you have to place them in the hole in the lid, due to the inevitable presence of the false male that configures the interior or sole of the sole floor.
En líneas generales, el molde para fabricar suelas para calzado, que la invención propone, consigue solucionar el problema comentado al construir la tapa del molde en dos piezas, de modo que tenemos una tapa propiamente dicha que lleva el macho, y un anillo o pieza anular donde están los huecos que forman la bandeleta, que es la zona donde están las tiras o insertos que ahora quedan al descubierto y totalmente accesibles.In general, the mold to manufacture soles for footwear, which the invention proposes, manages to solve the problem discussed when building the mold cover in two pieces, so that we have a proper cap that carries the male, and a ring or ring piece where the gaps that form the bandeleta, which is the area where the strips or inserts are now They are exposed and fully accessible.
Esta tapa y el anillo se unen solidariamente de forma sencilla al contar las superficies de contacto con unas ranuras en forma de "T" en proximidad a los laterales, de manera que con el molde cerrado coinciden ambas, que permitiendo introducir una regleta con sección en doble "T" ajustada a la embocadura formada con ellas, quedando unidas sólidamente esas dos partes del molde de forma que cuando la prensa abre o cierra, ambas piezas se mueven juntas como si de una sola se tratase.This cover and the ring are joined in solidarity with simple way to count the contact surfaces with "T" shaped grooves in proximity to the sides, of so that with the closed mold both coincide, allowing insert a strip with double section "T" adjusted to the mouth formed with them, solidly joining those two parts of the mold so that when the press opens or closes, both pieces move together as if it were only one.
Al mismo tiempo, el anillo lleva también practicado otro ranurado idéntico en la cara inferior y en proximidad a los laterales, pudiendo coincidir o no con los respectivos de la cara superior, de manera que mediante las mismas regletas, se pueden unir solidariamente el anillo con la placa intermedia, cuando así se requiera.At the same time, the ring also bears another identical grooved in the lower face and in proximity to the sides, may or may not coincide with the respective of the upper face, so that by the same strips, the ring can be joined in solidarity with the plate intermediate, when required.
Estas mismas ranuras existen también en la cara superior de la pieza restante inferior, la base del molde.These same grooves also exist on the face. top of the bottom remaining piece, the base of the mold.
Esta disposición permite realizar el moldeo con un sencillo método de fabricación acorde con la invención, sin mas que colocar las regletas entre las piezas pertinentes dependiendo de la fase de moldeo que se considere. La secuencia de movimientos tanto de la fase de moldeo como para la de desmoldeo, las veremos mas claramente en relación con las figuras.This arrangement allows molding with a simple manufacturing method according to the invention, without more have to place the strips between the relevant parts depending on the molding phase considered. The sequence of movements both the molding phase and the demolding phase, we will see more clearly in relation to the figures.

Haciendo referencia a la numeración adoptada en las figuras podemos ver que el molde para fabricar suelas para calzado, así como el correspondiente método de fabricación, que constituyen el objeto de la invención, presenta efectivamente las ventajas preconizadas en relación con la técnica actual de fabricación.Referring to the numbering adopted in the figures we can see that the mold to make soles for footwear, as well as the corresponding manufacturing method, which they constitute the object of the invention, it effectively presents the Advantages recommended in relation to the current technique of manufacturing.
Como se observa en las figuras 2 y 3, actualmente se emplea para construir el tipo de suelas (1) (ver figura 1) con bandeleta (2), un molde formado por tres piezas: tapa (4), placa intermedia (5) y base (6).As seen in figures 2 and 3, It is currently used to build the type of soles (1) (see Figure 1) with a tray (2), a mold consisting of three pieces: cover (4), intermediate plate (5) and base (6).
La tapa (4) lleva practicado un rehundido (7) cuya pared lateral (8) tiene talladas las contraformas de la bandeleta (2) con la geometría externa de esta. En el fondo del rehundido (7) queda acoplado un macho postizo (9) que ocupa el hueco interior de la suela (1) y permite la formación del espesor de la bandeleta (2) cuando se proceda a llenar el molde con el material, goma, de la bandeleta (2), siendo imposible colocar los insertos de otro color por la dificultad que supone la presencia del macho postizo (9).The lid (4) has a recess (7) whose side wall (8) has carved the counterforms of the bandeleta (2) with its external geometry. At the bottom of the recessed (7) a male insert (9) is occupied that occupies the hollow inside the sole (1) and allows the formation of the thickness of the tray (2) when the mold is filled with the material, rubber, of the bandeleta (2), being impossible to place the inserts of another color because of the difficulty of the presence of the male hairpiece (9).
La placa intermedia (5) cierra inferiormente la tapa (4) portadora del macho postizo (9) y a la vez cubre superiormente la base (6) que lleva practicado el rebaje (10) correspondiente a la parte inferior de la geometría del piso o suela propiamente dicha, donde se coloca también la goma. Después de una primera fase de semi-vulcanización, se retira la placa intermedia (5) y se unen directamente ambas partes (4 y 6) del molde para continuar la vulcanización y queden unidos el piso y la bandeleta (2) para formar la suela. El macho postizo (9) no llega a contactar con la placa intermedia (5) para así formar una capa superior (11) del piso, la cual se unirá íntimamente con la goma (12) del rebaje (10) de la base (6).The intermediate plate (5) closes the cover (4) carrier of the male insert (9) and at the same time covers superiorly the base (6) that has practiced the recess (10) corresponding to the bottom of the floor or sole geometry proper, where the rubber is also placed. after one first phase of semi-vulcanization, the intermediate plate (5) and both parts (4 and 6) of the mold to continue vulcanization and the floor and the bandeleta (2) to form the sole. The false male (9) does not reach contact the intermediate plate (5) to form a layer top (11) of the floor, which will be intimately joined with the rubber (12) of the recess (10) of the base (6).
Como se observa en la figura 4, la presente invención contempla como especial característica el construir una tapa del molde formada por dos piezas: una tapa (13) que lleva el macho (14) y un anillo (15) con los huecos que darán lugar a la geometría de la bandeleta (2). Así se pueden incorporar fácilmente tiras horizontales de otro color en la bandeleta (2).As seen in Figure 4, this invention contemplates as a special feature the construction of a cover of the mold formed by two pieces: a cover (13) that carries the male (14) and a ring (15) with the gaps that will give rise to the geometry of the tray (2). Thus they can be easily incorporated horizontal strips of another color on the tray (2).
Este molde (16) se complementa con una placa intermedia (17) y una base (18) con las mismas funciones que las anteriormente comentadas pero incorporando otras peculiaridades de las que trataremos seguidamente, y queda por tanto formado por cuatro piezas.This mold (16) is complemented with a plate intermediate (17) and a base (18) with the same functions as the previously commented but incorporating other peculiarities of which we will discuss next, and is therefore formed by four pieces.
La tapa (13) y el anillo (15) poseen unos ranurados longitudinales en "T" (19) en sus caras en contacto, que cuando se cierra el molde (16) forman un carril en doble "T" por el que se puede introducir una regleta (20) de idéntica sección, provista de un pomo de asido, con las que se mantienen solidarios formando un conjunto inseparable al abrir el molde (16).The cover (13) and the ring (15) have about longitudinal grooves in "T" (19) on their faces in contact, that when the mold is closed (16) form a double lane "T" by which you can enter a strip (20) of identical section, provided with a handle, with which they remain solidarity forming an inseparable set when opening the mold (16).
El anillo (15) presenta también otros ranurados (19) idénticos en su cara inferior, los cuales son coincidentes en posición con los ranurados (19) previstos en las caras superiores de la placa intermedia (17) y de la base (18). De esta forma se podrá unir solidariamente el anillo (15) con la placa intermedia (17) (figura 5), o con la base (18) (figura 9) dependiendo de la fase de moldeo que se considere, como veremos mas adelante. Solo son necesarias dos regletas (20), pues nunca están unidos mas de dos piezas del molde (16). En la figura 4 las regletas (20) están introducidas en los ranurados (19) del anillo (15) y placa intermedia (17), y en la figura 8 están uniendo la tapa (13) con el anillo (15).The ring (15) also has other grooves (19) identical on its lower face, which are coincident in position with the grooves (19) provided on the upper faces of the intermediate plate (17) and the base (18). This way you can jointly join the ring (15) with the intermediate plate (17) (figure 5), or with the base (18) (figure 9) depending on the phase of molding that is considered, as we will see later. Only are two strips (20) are necessary, since they are never joined more than two mold pieces (16). In figure 4 the strips (20) are inserted in the grooves (19) of the ring (15) and plate intermediate (17), and in figure 8 they are joining the cover (13) with the ring (15).
Para el manejo del molde (16) al realizar el método de fabricación propuesto, se parte de la posición de cerrado (figura 5) y estando unido el anillo (15) con la placa intermedia (17) mediante las dos regletas (20). Se abre el molde (16) (figura 6) quedando solidario el anillo (15) con la placa intermedia (17), la tapa (13) retirada y la base (18) separada de la placa intermedia (17). Se coloca después la goma y los insertos (21) si los hubiera, en la oquedad del anillo (15) y en esta misma fase se coloca goma también en la base (18) y se cierra el molde (16) (figura 7). Entonces se cambian de posición las regletas (20) para que sujeten el anillo (15) con la tapa (13). Al tiempo indicado se abre el molde (16) (figura 8) quedando la placa intermedia (17) separada y aislada tanto del conjunto anillo (15) con su tapa (13), como de la base (18). En estas condiciones se retira la placa intermedia (17) y se cierra el molde (16) (figura 9) para que entren en contacto el anillo (15) con la base (18) y se complete la vulcanización de la goma del conjunto, cambiando de posición las regletas (20). Después de que transcurra el tiempo reglamentario se abre el molde (16) (figura 10) levantando la tapa (13) y se efectúa la extracción de la suela (1) sin dificultad.For the handling of the mold (16) when making the proposed manufacturing method, it starts from the closed position (figure 5) and the ring (15) being connected with the intermediate plate (17) by means of the two strips (20). The mold (16) is opened (figure 6) the ring (15) being integral with the intermediate plate (17), the cover (13) removed and the base (18) separated from the intermediate plate (17). The rubber and inserts (21) are then placed, if any, in the cavity of the ring (15) and in this same phase rubber is placed also in the base (18) and the mold (16) is closed (figure 7). Then the strips (20) are repositioned to hold the ring (15) with the cover (13). At the indicated time the mold is opened (16) (figure 8) leaving the intermediate plate (17) separated and isolated both the ring assembly (15) with its cover (13), and the base (18). Under these conditions the intermediate plate (17) is removed and close the mold (16) (figure 9) so that the ring (15) with the base (18) and the vulcanization of the rubber of the set, changing the position of the strips (20). After After the regulation time elapses, the mold is opened (16) (figure 10) by lifting the cover (13) and the removal of the sole (1) without difficulty.
El último paso se puede obviar si la extracción del piso no es dificultosa, siguiendo unida la tapa (13) con el anillo (15), pues en este caso el piso sale junto al macho (14). Es recomendable desmontar estas dos piezas (13-15) porque el piso queda en el conjunto anillo/base y se extrae como si de un molde normal se tratase, provocando menos daños a la suela (1).The last step can be ignored if the extraction of the floor is not difficult, following the cover (13) together with the ring (15), because in this case the floor comes out next to the male (14). Is It is advisable to disassemble these two pieces (13-15) because the floor is in the ring / base set and is removed as if It was a normal mold, causing less damage to the sole (one).
Para comenzar un nuevo ciclo, se cierra el molde (16), se cambian las regletas (20) para unir tapa (13) y anillo (15), se abre el molde (16) y se introduce la placa intermedia (17). Se cierra el molde (16) y se pasan las regletas (20) a la posición anillo (15)/placa intermedia (17), y se inicia el ciclo.To start a new cycle, the mold is closed (16), the strips (20) are changed to join cover (13) and ring (15), the mold (16) is opened and the intermediate plate (17) is introduced. The mold (16) is closed and the strips (20) are passed to the position ring (15) / intermediate plate (17), and the cycle is started.
