Description
Maneta de apertura de puerta de horno de cocción.Oven door opening handle cooking.
La presente invención, según se expresa en el enunciado de esta memoria descriptiva, se enmarca en el campo de los hornos de cocción domésticos y en concreto en el área de los tiradores o manetas para la apertura de las puertas de dichos aparatos.The present invention, as expressed in the enunciated of this descriptive memory, is framed in the field of domestic cooking ovens and specifically in the area of handles or handles for opening the doors of said appliances
Las manetas de apertura de las puertas de hornos con volúmenes, suelen hacerse por inyección de plástico con gas nitrógeno que forma una burbuja en el interior de la maneta. Así se ahorra material plástico. Sobre todo se ahorra material en el asa, que es donde se concentra más cantidad de plástico.The opening handles of the oven doors with volumes, usually done by injection of plastic with gas nitrogen that forms a bubble inside the handle. Thus Save plastic material. Above all, you save material on the handle, which is where more plastic is concentrated.
En según qué geometrías más complicadas, no es posible hacer inyección con gas, ya que la superficie final no queda regular.In what geometries more complicated, it is not possible gas injection, since the final surface is not It is regular.
En las manetas de tipo tubular de arco, donde el asa es la maneta prácticamente completa, no hay ningún problema en su fabricación, y es la manera más barata de construirse. En el caso de geometrías más complicadas, los moldes tienden a ser más complejos y el plástico fundido tiene más problemas para llegar a todas las esquinas del molde, debido a lo cual el gas puede formar la burbuja demasiado cerca de la pared del mismo, en detrimento de la calidad y estética. Al no salir bien la superficie, por irregularidades en la misma, hay que retirar estas piezas con malformaciones.In the tubular arc type handles, where the handle is the practically complete handle, there is no problem in its manufacture, and it is the cheapest way to build it. In the case of more complicated geometries, the molds tend to be more complexes and molten plastic has more trouble getting to all corners of the mold, due to which the gas can form the bubble too close to its wall, to the detriment of The quality and aesthetics. When the surface does not go well, for irregularities in it, you have to remove these pieces with malformations
Por lo tanto, lo más normal en geometrías complejas es hacer las manetas abiertas y con la abertura en una zona que no sea visible. Esto hace que disminuya notablemente la resistencia.Therefore, the most normal in geometries complex is to make the handles open and with the opening in one area that is not visible. This causes the decrease in the resistance.
El objeto de la invención es una maneta de apertura de puerta de horno de cocción, del tipo de las que se obtienen por inyección de plástico, teniendo una geometría que incluye al menos una abertura caracterizada porque una vez enfriada y sacada la maneta del molde, la abertura es cerrada al menos en parte por una tapa mediante soldadura por vibración, determinándose una unidad compacta.The object of the invention is a handle of cooking oven door opening, of the type of which obtained by plastic injection, having a geometry that includes at least one opening characterized because once cooled and removed the handle of the mold, the opening is closed at least in part by a cover by vibration welding, determining a compact unit
Ambas piezas ya es posible inyectarlas sin gas, cosa que es mucho más sencillo que la inyección con gas. Solo los moldes son ya mucho más simples.Both pieces can already be injected without gas, which is much simpler than gas injection. Only the Molds are already much simpler.
Durante el proceso, la temperatura del plástico aumenta hasta que se funden maneta y tapa, quedando de una pieza hueca y resistente con el consiguiente ahorro de material que implica.During the process, the temperature of the plastic increases until handle and lid melt, remaining one piece hollow and resistant with the consequent saving of material that it implies.
La abertura se encuentra en un asa de la maneta, que es donde más material se puede evitar en la inyección y además se encuentra en la parte inferior del asa con lo que se oculta del campo más normal de visión.The opening is in a handle handle, which is where more material can be avoided in the injection and also It is located at the bottom of the handle with what is hidden from the more normal field of vision
La abertura esta constituida por dos paredes paralelas que facilitan el desmoldeo de la pieza en la máquina de inyección.The opening consists of two walls parallels that facilitate the demoulding of the piece in the machine of injection.
La tapa es del mismo material plástico que la maneta cosa que facilita su soldadura por microvibraciones. Puede ser de todos modos otro material para darle alguna estética especial, como una tapa metálica que cierra completamente la abertura dándole más resistencia a la tracción y más cerrada para su limpieza.The lid is of the same plastic material as the handle which facilitates microvibration welding. May be another material anyway to give it some aesthetic special, like a metal lid that completely closes the opening giving it more tensile strength and more closed for cleaning
De esta forma las geometrías complejas quedarán muy compactas sin problemas superficiales como los que tendría si se hubiera inyectado con gas, consiguiéndose nuevas posibilidades.In this way complex geometries will remain very compact without superficial problems like the ones you would have if would have been injected with gas, getting new possibilities.
Para facilitar la comprensión de las características de la invención y formando parte integrante de esta memoria descriptiva, se acompañan unas hojas de dibujos en cuyas figuras, con carácter ilustrativo y no limitativo se ha representado lo siguiente:To facilitate the understanding of characteristics of the invention and forming an integral part of this Descriptive report, accompanying some sheets of drawings in whose figures, with an illustrative and non-limiting nature represented the following:
Figura 1.- Es una vista parcial y en perspectiva, que muestra esquemáticamente una maneta de apertura de puertas de hornos, construida acorde con la invención y estando la tapa que ha de cerrar la abertura formada en ella, explosionada.Figure 1.- It is a partial and perspective view, which schematically shows a door opening lever ovens, built in accordance with the invention and the lid being to close the opening formed in it, exploded.
Figura 2.- Es una sección transversal, con un detalle ampliado, de lo mostrado en la figura 1, en una zona ocupada por la tapa y estando ésta en la posición de "cierre".Figure 2.- It is a cross section, with a enlarged detail, as shown in figure 1, in an area occupied by the lid and being in the position of "closing".
Haciendo referencia a la numeración adoptada en las figuras, podemos ver cómo la maneta de apertura de puertas de hornos, que la invención propone, tal como la referenciada en general con el número 1 que se muestra parcialmente en la figura 1, es hueca al estar dotada de la abertura inferior 2 y que es obtenida por el procedimiento de inyección de plástico sin necesidad de inyección con gas.Referring to the numbering adopted in the figures, we can see how the door opening handle of ovens, which the invention proposes, such as the one referenced in general with the number 1 partially shown in figure 1, it is hollow as it is provided with the lower opening 2 and which is obtained by plastic injection procedure without need Gas injection.
La maneta 1 incluye un asa 6 con una abertura 2 en su parte inferior que quedará cerrada con la tapa 3 del mismo material plástico que el resto. La abertura 2 se abre desde abajo y es flanqueada por las paredes 4 y 5.Handle 1 includes a handle 6 with an opening 2 in its lower part that will be closed with the lid 3 thereof plastic material than the rest. The opening 2 opens from below and It is flanked by walls 4 and 5.
La unión de la tapa 3 a las paredes 4 y 5 de la abertura 2, se obtiene mediante soldadura por micro vibración, formándose así un cuerpo monobloque compacto.The connection of the cover 3 to the walls 4 and 5 of the opening 2, is obtained by micro vibration welding, thus forming a compact monobloc body.
Como dijimos anteriormente, la tapa 3 puede cubrir totalmente la abertura, en dirección longitudinal del asa 6 de la maneta de apertura, o solamente en la zona o zonas más debilitadas, o en general donde se haga necesario conseguir mayor resistencia para lograr la rigidez debida que ha de tener la maneta.As we said before, cover 3 can fully cover the opening, in the longitudinal direction of the handle 6 of the opening handle, or only in the zone or zones more weakened, or in general where it becomes necessary to get more resistance to achieve the proper rigidity that the handle
