Abstract
Description
Dispositivo de desmoldeo de negativos.Negative demoulding device.
La presente invención se refiere a un dispositivo de desmoldeo de negativos, especialmente en el moldeo en plástico.The present invention relates to a device negative demoulding, especially in molding in plastic.
En la actualidad son conocidos varios sistemas de desmoldeo de negativos en un proceso de moldeo en plástico.At present several systems of demolding of negatives in a plastic molding process.
Uno de los sistemas conocidos consta de una barra de sección rectangular o circular rebajada hasta una altura que permite flexionar y liberar el negativo del molde.One of the known systems consists of a bar rectangular or circular section lowered to a height that allows to flex and release the negative from the mold.
El montaje y desmontaje de la pieza se hace desde la placa de expulsión.The assembly and disassembly of the piece is done from the eject plate
Uno de los inconvenientes que esto implica es que en caso necesario de recambio por rotura o desgaste de esta pieza se debe cambiar entera por una nueva.One of the disadvantages that this implies is that if necessary, replacement due to breakage or wear of this part must be changed whole for a new one.
El tiempo necesario para mecanizar el alojamiento de la pieza es considerable implica costes importantes.The time needed to mechanize the housing The piece is considerable implies significant costs.
Otro sistema conocido consiste en utilizar dos piezas de acero, una más o menos compleja de forma y abatible y la otra pieza denominada casquillo cilíndrico con cabeza cilíndrica fija.Another known system is to use two steel pieces, a more or less complex in shape and folding and the another piece called cylindrical bushing with cylindrical head fixed.
La pieza abatible se monta sobre un eje.The folding part is mounted on a shaft.
El sistema no flexa y el desplazamiento se produce mecánicamente a través de un eje.The system does not flex and the displacement is mechanically produced through an axis.
El montaje y desmontaje de las piezas se hace desde la expulsión del molde.The assembly and disassembly of the pieces is done since the expulsion of the mold.
En el caso necesario de recambio por rotura o desgaste se puede cambiar la pieza abatible.If necessary, replacement due to breakage or wear can change the folding piece.
El ajuste de las dos piezas es cilíndrico con reducida conicidad por tanto este sistema presenta dos problemas:The adjustment of the two pieces is cylindrical with reduced conicity therefore this system has two problems:
- La presión de inyección del plástico puede modificar la posición de la pieza abatible y producir alteración en la geometría de las piezas, rebabas.- Plastic injection pressure can modify the position of the folding piece and produce alteration in the geometry of the pieces, burrs.
- Como tiene mayor superficie cilíndrica necesita más recorrido para abatir la primera pieza.- As it has a larger cylindrical surface, it needs more travel to bring down the first piece.
Para evitar estos problemas que presentan estos sistemas conocidos se ha ideado el dispositivo de la invención que presenta con respecto a los ya citados una serie de ventajas que inciden no sólo en el desmoldeo sino también en el almacenamiento y trasporte.To avoid these problems that present these known systems the device of the invention has been devised that it presents with respect to those already mentioned a series of advantages that they affect not only the demoulding but also the storage and transportation
El dispositivo de la invención comprende un casquillo guía en el que se acopla interiormente un patín.The device of the invention comprises a guide bushing in which a skate is engaged internally.
Ambas piezas son de acero.Both pieces are made of steel.
El casquillo es cilíndrico y presenta un ensanchamiento extremo prismático dotado de dos taladros para la fijación del casquillo mediante tornillos a la parte correspondiente y fija del molde.The bushing is cylindrical and has a Prismatic widening endowed with two holes for fixing of the bushing by means of screws to the part corresponding and fixed mold.
El patín comprende dos piezas de acero que quedan por el interior del casquillo. Estas dos piezas van relacionadas por medio de un pasador.The skate comprises two pieces of steel that remain inside the cap. These two pieces are related by means of a pin.
Además, las dos piezas citadas del patín se encuentran relacionadas lateralmente por medio de un muelle que se aloja en sendos rehundidos practicados en estas dos piezas.In addition, the two cited parts of the skate are they are related laterally by means of a spring that lodges in two rehundidos practiced in these two pieces.
El casquillo que es preferentemente cilíndrico presenta un ensanchamiento con dos taladros en los que se montan los tornillos de fijación a la parte fija correspondiente del molde.The bushing that is preferably cylindrical It has a widening with two holes in which they are mounted the fixing screws to the corresponding fixed part of the mold.
Una de las piezas del patín es cilíndrica con una parte extrema prismática que remata en dos orejetas perforadas iguales, paralelas y enfrentadas que determinan un espacio en el que se acopla una orejeta perforada extrema de la otra pieza, relacionándose las orejetas por medio de un pasador.One of the skate pieces is cylindrical with a prismatic end part that ends in two perforated lugs equal, parallel and opposite that determine a space in the that an extreme perforated lug of the other piece is attached, relating the lugs by means of a pin.
La otra pieza extrema es prismática y muestra una de sus caras laterales mayores inclinada.The other extreme piece is prismatic and shows a of its inclined major lateral faces.
La pieza cilíndrica del patín muestra un taladro ciego roscado en el que se acopla el tornillo de fijación a la parte desplazable del molde.The cylindrical part of the skate shows a drill blind thread in which the fixing screw is attached to the movable part of the mold.
El muelle que relaciona las dos piezas del patín permite el desplazamiento lateral flexible de la pieza extrema prismática del propio patín, tanto en el recorrido de salida como en el recorrido de entrada del casquillo.The spring that connects the two pieces of the skate allows flexible lateral displacement of the end piece Prismatic of the skate itself, both on the starting route and in the entry path of the bushing.
La figura 1 muestra una vista lateral del patín del dispositivo de la invención.Figure 1 shows a side view of the skate of the device of the invention.
La figura 2 muestra una vista lateral del dispositivo en una serie de posiciones intermedias a las dos posiciones extremas correspondientes.Figure 2 shows a side view of the device in a series of intermediate positions at two corresponding extreme positions.
La figura 3 muestra una vista en perspectiva de la pieza extrema superior del patín.Figure 3 shows a perspective view of the upper end piece of the skate.
La figura 4 muestra vista lateral de la figura 3.Figure 4 shows side view of the figure 3.
La figura 5 muestra una vista en perspectiva de la otra pieza del patín.Figure 5 shows a perspective view of The other piece of the skate.
La figura 6 muestra una vista lateral de la figura 5.Figure 6 shows a side view of the figure 5.
La figura 7 muestra una vista seccionada de la figuras 5.Figure 7 shows a sectional view of the figures 5.
El dispositivo 1 está constituido por un casquillo 2 y un patín 3.The device 1 is constituted by a cap 2 and a skate 3.
El casquillo 2 presenta un ensanchamiento extremo 4 dotado de taladros 5 para acoplar tornillos de fijación a la parte fija del molde.The bushing 2 has an extreme widening 4 equipped with drills 5 for attaching fixing screws to the fixed part of the mold.
Por el interior del casquillo se posiciona el patín 3 constituido de dos piezas 6 y 7 relacionadas por un pasador 8.Inside the bushing the skate 3 consisting of two pieces 6 and 7 related by a pin 8.
Una de las piezas, la 7, está determinada por una zona cilíndrica 9 y otra forma prismática 10 que remata por su extremo en dos orejetas 11 paralelas perforadas 12.One of the pieces, 7, is determined by a cylindrical zone 9 and another prismatic shape 10 that ends at its end in two perforated parallel lugs 11.
La otra pieza 6 muestra forma prismática dotada de una orejeta 13 perforada que se acopla en el espacio 14 definido entre las dos orejetas 11.The other piece 6 shows a prismatic shape of a perforated lug 13 that engages in space 14 defined between the two lugs 11.
