Description

Expulsores de matriz para embuticiones por presión perfeccionados.Matrix ejectors for drawing by perfected pressure.

Objeto de la invenciónObject of the invention

La invención, tal como expresa el enunciado de la presente memoria descriptiva, se refiere a unos expulsores de matriz para embuticiones por presión perfeccionados, aportando a la función a que se destinan ventajas y características de novedad, que mejoran los ya conocidos en el mercado para el mismo fin.The invention, as expressed in the statement of The present specification refers to ejectors of matrix for perfected pressure drawing, contributing to the function to which advantages and novelty features are destined, that improve those already known in the market for the same purpose.

Más en particular, el objeto de la invención se centra en unos expulsores de matriz para embuticiones por medio de presión, especialmente matrices del tipo destinado, adecuadamente posicionada en un compostor, para la realización de embuticiones de placas de matrícula y/o elementos similares, los cuales incorporan una serie de regruesamientos o resaltes que mejoran sustancialmente su efectividad.More particularly, the object of the invention is focuses on matrix ejectors for drawing by means of pressure, especially matrices of the type intended, properly positioned in a compostor, for the realization of deep drawing of  license plates and / or similar elements, which incorporate a series of regruesamientos or projections that improve substantially its effectiveness

Antecedentes de la invenciónBackground of the invention

Como es sabido, una vez realizada la embutición de la placa de matrícula o elemento similar a realizar, deben separarse ambas partes de la matriz, para lo cual una de ellas dispone de los denominados expulsores, constituidos por elementos o cuerpos de poliuretano que facilitan dicha operación, evitando durante la aplicación de la presión que ambas partes de la matriz se queden pegadas o enganchadas a la placa.As is known, once the drawing is done of the license plate or similar item to perform, must separate both parts of the matrix, for which one of them It has the so-called ejectors, consisting of elements or polyurethane bodies that facilitate this operation, avoiding during the application of the pressure that both parts of the die they remain stuck or hooked to the plate.

Estos expulsores, en las matrices convencionales, se encuentran situados en la zona perimetral a la cavidad o resaltes, es decir, exteriormente al grafismo, provocando el inconveniente de que, al aplicar presión sobre ellos la prensa, quedan marcas en la placa alrededor de los grafismos, que obviamente resultan antiestéticas.These ejectors, in the matrices conventional, they are located in the perimeter zone to the cavity or projections, that is, externally to the graphics, causing the drawback that, by applying pressure on them the press, marks remain on the plate around the graphics, which They are obviously unsightly.

Para solucionar dicha problemática, el propio solicitante es titular de un modelo de utilidad nº U200600425, referido a unos expulsores de matriz para embuticiones por medio de presión, en el que dichos expulsores están constituidos por pequeños elementos independientes aptos para ser incorporados o insertados en el interior de la zona hueca creada especialmente para tal fin en la zona central de la parte macho de la matriz adaptándose a las distintas formas que dicho grafismo tiene en cada caso, los cuales, además, presentan en su parte superior un resalte o tetón destinado a absorber la presión ejercida por la prensa.To solve this problem, the own applicant is the holder of a utility model No. U200600425, referred to matrix ejectors for drawing by means of pressure, in which said ejectors are constituted by small independent elements suitable for incorporation or inserted inside the hollow area specially created for this purpose in the central area of the male part of the matrix adapting to the different forms that this graphics has in each case, which, in addition, present in its upper part a highlight or stud intended to absorb the pressure exerted by the press.

Dicha solución, si bien mejora la efectividad de los expulsores convencionales, presenta todavía ciertos aspectos susceptibles de ser mejorados, particularmente referidos a la complejidad y laboriosidad que requiere la colocación de los mismos, al ser elementos individuales que se van posicionan en función de la forma de cada grafismo, y por otra parte, al quedar dispuesto en orientaciones distintas, según la forma que tenga dicho grafismo, no siempre permiten efectuar el levantamiento de la placa con la misma facilidad.This solution, although it improves the effectiveness of conventional ejectors, it still presents certain aspects liable to be improved, particularly referring to the complexity and industriousness that requires the placement of themselves, being individual elements that are positioned in function of the shape of each graphic, and on the other hand, when remaining arranged in different orientations, depending on the form said graphics, do not always allow the lifting of the plate with the same ease.

Es, pues, el objetivo de la presente invención desarrollar un nuevo tipo de expulsores perfeccionados que solventen de manera práctica los inconvenientes anteriormente descritos, permitiendo una colocación de los mismos en la matriz mucho más rápida y simple y mejorando la efectividad en el momento de quitar la placa tras la operación de embutición.It is therefore the objective of the present invention develop a new type of improved ejectors that solve the problems in a practical way before described, allowing their placement in the matrix much faster and simpler and improving effectiveness at the moment of removing the plate after the drawing operation.

Explicación de la invenciónExplanation of the invention.

Así, los expulsores de matriz para embuticiones por presión perfeccionados que la presente invención propone se configura como una novedad dentro de su campo de aplicación, ya que, a tenor de su implementación se alcanzan satisfactoriamente y de manera taxativa los objetivos anteriormente señalados como idóneos, estando los detalles caracterizadores que lo hacen posible y los distinguen de lo ya conocido en el mercado, ampliamente expuestos a continuación y adecuadamente recogidos en las reivindicaciones finales que acompañan a la presente memoria descriptiva.Thus, matrix ejectors for drawing perfected pressure that the present invention proposes is configure as a novelty within its field of application, since which, according to their implementation, are satisfactorily achieved and in a restrictive manner the objectives indicated above as suitable, being the characterizing details that make it possible and distinguish them from what is already known in the market, widely exposed below and properly collected in the Final claims that accompany this report descriptive

De manera concreta los expulsores preconizados con la presente invención se constituyen a partir de un cuerpo de poliuretano, goma o cualquier otro material elástico, que, adoptando la configuración del grafismo a embutir para permitir su colocación en el hueco de dicho grafismo en la parte hembra de la matriz, cuentan, en su superficie superior, con una pluralidad de resaltes longitudinales, separados entre sí, preferentemente, de forma equidistante, y preferentemente idénticos, los cuales están dispuestos, siempre, con la misma orientación y en posición horizontal, es decir, paralela respecto al eje horizontal del grafismo a embutir.Specifically the recommended ejectors with the present invention they are constituted from a body of polyurethane, rubber or any other elastic material, which, adopting the graphic design to be embedded to allow its placement in the hollow of said graphics in the female part of the matrix, have, on their upper surface, a plurality of longitudinal projections, separated from each other, preferably from equidistant form, and preferably identical, which are willing, always, with the same orientation and position horizontal, that is, parallel to the horizontal axis of the graphic design.

De esta forma, al consistir dichos resaltes en elevaciones sobre la pieza expulsor, dispuestas todas en la misma dirección horizontal, facilitan en gran medida la extracción de la placa de matrícula, ya que ésta, al ser generalmente una placa rectangular apaisada, más larga que ancha, se podrá extraer en el mismo sentido de los citados resaltes, reduciéndose, ventajosamente, el tiempo invertido en tal operación, lo cual, lógicamente, repercute en el coste final del producto. Además, aunque la placa a embutir presente cualquier otra configuración, conociendo la orientación horizontal de los citados resaltes de los expulsores, el operario agilizará en gran medida la operación de extracción de las placas.In this way, as these highlights consist of elevations on the ejector piece, all arranged therein horizontal direction, greatly facilitate the extraction of the license plate, since this, being generally a license plate landscape rectangular, longer than wide, can be extracted in the same sense of the mentioned highlights, reducing, advantageously, the time invested in such an operation, which, logically, it affects the final cost of the product. Further, although the plate to be embedded has any other configuration, knowing the horizontal orientation of the mentioned highlights of the ejectors, the operator will greatly expedite the operation of plate removal.

Los descritos expulsores de matriz para embuticiones por presión perfeccionados representan, por consiguiente, una estructura innovadora de características estructurales y constitutivas desconocidas hasta ahora para tal fin, razones que unidas a su utilidad práctica, la dotan de fundamento suficiente para obtener el privilegio de exclusividad que se solicita.The described matrix ejectors for perfected pressure drawing represent, by consequently, an innovative structure of features structural and constitutive unknown so far for such end, reasons that together with its practical utility, endow it with sufficient basis to obtain the privilege of exclusivity that is requested.
