Abstract
Disclosed is a lightweight silica-sand core suitable for producing two brake calipers, characterised in that it comprises two cylindrical areas, a first cylindrical area (1) and a second cylindrical area (2), aligned and separated from each other by a central area (3 and 4), wherein the first central area (3) is disposed on an upper face (A) and provided with first entrances (5) that define an area for supporting brake pads, while the second central area (4) is defined on a lower face (B) and provided with second entrances (6), such that the first entrances (5) and the second entrances (6) are close to the first cylindrical area (A) and the second cylindrical area (B), resulting in the first entrances (5) and the second entrances (6) being misaligned. Owing to the design of the lightweight core, two brake calipers can be produced using each core.

Caracteriza a la presente invención el especial diseño aligerado y configuración del macho que está pensado de manera que permite la obtención de dos pinzas con un solo macho, lo que redunda en una reducción de costes al optimizar el display de la máquina, introduciendo un mayor número de pinzas por cada molde fabricado. The present invention is characterized by the special lightweight design and configuration of the male, which is designed in such a way that it allows obtaining two clamps with a single male, which results in a reduction in costs by optimizing the display of the machine, introducing a greater number of tweezers for each manufactured mold.
Por lo tanto, la presente invención se circunscribe dentro del ámbito de la fabricación de frenos, preferentemente frenos de disco, y de manera particular de entre las pinzas empleadas en ellos y de modo más preciso de entre el molde empleado en la fabricación de los moldes.Therefore, the present invention is circumscribed within the field of brake manufacturing, preferably disc brakes, and particularly among the calipers used in them and more precisely among the mold used in the manufacture of the molds. .

La fabricación de las pinzas (caliper) para frenos de disco requiere el empleo de un macho para la obtención de la zona hidráulica. La fabricación de cada pinza se realiza empleando un macho que es válido para una pinza. Esta disposición, que supone el empleo de un macho por unidad fabricada, implica un aprovechamiento reducido de la superficie útil de la maquina moldeadora. El no aprovechamiento de la superficie útil genera un coste de fabricación elevado derivado del número de unidades producidas por cada unidad de molde de arena fabricado.The manufacture of calipers for disc brakes requires the use of a male to obtain the hydraulic zone. The manufacture of each clamp is carried out using a male that is valid for a clamp. This provision, which involves the use of one core per manufactured unit, implies a reduced use of the useful surface of the molding machine. Not taking advantage of the useful area generates a high manufacturing cost derived from the number of units produced for each sand mold unit manufactured.
Por lo tanto, es objeto de la presente invención superar los inconvenientes derivados del empleo de un macho para cada pinza fabricada y por lo tanto de los costes de fabricación, desarrollando un macho como el que a continuación se describe y queda recogido en su esencialidad en la reivindicación primera.Therefore, the object of the present invention is to overcome the drawbacks derived from the use of a male for each manufactured clip and therefore the manufacturing costs, developing a male such as the one described below and is collected in its essentiality in the first claim.

Es objeto de la presente invención un macho de arena de sílice, aligerado y válido para la fabricación de dos pinzas de freno aplicables en los vehículos de pasajeros y vehículos ligeros de carga.The object of the present invention is a silica sand core, lightened and valid for the manufacture of two brake calipers applicable in passenger vehicles and light cargo vehicles.
El macho objeto de la invención presenta un diseño y configuración tal que permite la fabricación de dos pinzas con un solo macho, lo que redundará en una reducción del costo de fabricación al poder fabricar más unidades de pinza por unidad de molde generado.The core object of the invention has a design and configuration such that it allows the manufacture of two clamps with a single core, which will result in a reduction in the manufacturing cost by being able to manufacture more clamp units per generated mold unit.
El macho está formado por dos zonas cilíndricas, una primera zona cilíndrica y una segunda zona cilíndrica, ambas dispuestas de manera alineadas según un eje longitudinal y separadas entre sí por la zona central del macho que presenta una cara superior, una cara inferior, un primer costado y un segundo costado.The core is made up of two cylindrical areas, a first cylindrical area and a second cylindrical area, both arranged aligned along a longitudinal axis and separated from each other by the central area of the core that has an upper face, a lower face, a first side and a second side.
Tanto en la cara superior del macho como en la cara inferior del mismo está definida una zona de apoyo de las pastillas de freno o “fingers”, dichas zonas de apoyo de las pastillas en cada una de las caras comprenden unos entrantes, quedando los entrantes, por ejemplo de la cara superior, próximos a la primera zona cilíndrica, mientras que los entrantes de la cara inferior están próximos a la segunda zona cilíndrica, por lo que los entrantes de cada cara del macho no están alineados.Both on the upper face of the male and on the lower face of the same, a support zone for the brake pads or "fingers" is defined, said support zones for the pads on each of the faces comprise recesses, the recesses being , for example on the upper face, close to the first cylindrical zone, while the recesses on the lower face are close to the second cylindrical zone, so the recesses on each face of the core are not aligned.
Dicha posición relativa no enfrentada de los entrantes que sirven para definir el apoyo de las pastillas, hace que tanto según un eje longitudinal y según un eje transversal se garantiza la correcta fluidez de arena durante el proceso de fabricación del macho.Said non-facing relative position of the recesses that serve to define the support of the pellets means that both along a longitudinal axis and along a transverse axis the correct fluidity of sand is guaranteed during the core manufacturing process.
Adicionalmente, de manera preferente pero no limitativa, el macho de arena de sílice, aligerado y válido para para la fabricación de dos pinzas de freno cuenta con una reducción de volumen que consiste en un vaciado en una cara lateral, Este vaciado es generado por un elemento positivo introducido en la caja de machos y tendrá una geometría que estará determinada por la propia geometría de la pinza (caliper) a fabricar, por los espacios generados entre los cilindros y las dimensiones de los apoyos de pastillas de freno.Additionally, preferably but not limited to, the silica sand core, lightened and valid for the manufacture of two brake calipers, has a volume reduction consisting of a hole in one side face. This hole is generated by a positive element inserted in the core box and will have a geometry that will be determined by the actual geometry of the caliper to be manufactured, by the spaces generated between the cylinders and the dimensions of the brake pad supports.
Dicho vaciado tendrá como consecuencia una reducción de volumen y por lo tanto de peso, lo que redunda en un ahorro y la consiguiente no utilización de las materias primas necesarias, lo que supone un impacto ambiental positivo.Said emptying will result in a reduction in volume and therefore in weight, which results in savings and the consequent non-use of the necessary raw materials, which has a positive environmental impact.
