Definitions
- the present invention relates to a thermoforming process of flexible laminar pieces, which makes it possible to reproduce three-dimensional surfaces to obtain pieces or objects with finished shapes, especially based on plastic materials.
- the process of the invention is carried out by means of a tool comprising at least one deformable surface on which, once the forms to be obtained are reproduced, the sheet to be formed is attached and the thermoforming thereof is carried out. , by applying heat on the sheet, which will then be pushed against the surface reproduced in the tool.
- thermoforming process of plastic parts laminar pieces is already known, by means of a mold that is created from a deformable surface. On the deformable surface created the sheet piece to be formed is arranged and then the thermoforming thereof is applied, applying heat on the sheet piece, at the same time that vacuum is created between the sheet piece and the mold surface, through holes suckers. Another problem is that each time we proceed with forming with different shapes, it is necessary to create a new mold.
- a tool for forming templates is known from US4510636, consisting of an infinity of attached and axially movable stems, which are mounted in a box. By applying certain shapes (sole of the foot) on the sterile end of the stems, the same shapes are reproduced at the inner end. On the forms reproduced at the inner end of the stems, which remain inside the box, the piece is applied to form the template, which is formed by pressurized air inflated in the chamber.
- the template forming is done on the end of the stems opposite to the one on which the shape to be obtained was reproduced and also the forming is done by direct application of pressure on the external surface of the template, opposite to the support surface on the stems.
- the present invention has as its object a thermoforming process of flexible laminar pieces, of the type initially exposed, in which the surface reproduced on the deformable surface of the tool has an infinity of points and / or lines through which vacuum is created and that are located close to each other.
- a complete adaptation thereof is achieved to the mold shapes and thereby a perfect reproduction of the desired shapes in the laminar piece.
- thermoforming of the laminar piece is carried out by means of a tool that has a deformable surface, constituted by an infinity of small independent areas, which can be supported by axially displaceable stems or be constituted by the section of said stems, which are mounted in a sealed lower chamber.
- the small independent areas are separated by interstices that communicate with the lower sealed chamber, which in turn has a mouth through which said chamber can be connected with a vacuum source.
- the necessary vacuum effect can be applied through the aforementioned interstices on the lower surface of the sheet to allow this piece to be applied on the forms reproduced by the ends of the stems and perfectly adapts to said shapes.
- the process of the invention is carried out with a mold of the exposed type and comprises the following steps:
- the deformable surface of the mold is constituted by an infinity of small independent areas separated by interstices through which the vacuum is applied to the sheet, to propel said piece against the independent areas and keep it attached on the same, all at the same time that heat is applied on the sheet.
- the tool by which the process of the invention is carried out comprises a deformable surface consisting of countless small independent areas supported by axially movable stems, or defined by the section of the stems themselves, which are mounted in a waterproof bottom chamber.
- the small independent areas that define the deformable surface are separated by interstices that communicate with the sealed chamber, which has a mouth for connection to a vacuum source.
- the interstices that separate the small independent areas may consist of holes, grooves, or holes and grooves.
- the stems can be propelled towards the position extracted by any system and also have means to block said stems in any retracted position and that when released from these means will recover the extracted position.
- the displacement of the independent areas can be achieved by applying pressure on them, or by pulling the stems that support it.
- the form to be obtained with the tool can be achieved by supporting and pressing the model to be reproduced on the set of independent areas, to achieve their displacement until the forms of the supported surface are reproduced.
- the shapes that are desired to be obtained on the deformable surface of the tool can be achieved by pulling the stems that support the plates, for example through a computer-controlled mechanical system.
- Figure 2 shows in longitudinal section the tool of Figure 1, with a foot applied on it.
- Figure 3 corresponds to detail A of figure 1 on a larger scale.
- Figure 4 is a view similar to Figure 2, with a sheet of thermoformed plastic material on the tool.
- the attached drawings show a tool comprising a platform (1) that is composed of an infinite number of independent areas (2) of small dimensions, which are all located in the same plane and each of which is supported by an axially movable rod (3). All the rods (3) are parallel and are mounted in a support box (4), so that they can move axially between a position of maximum extraction, in which the areas (2) remain in coplanar position, and a position of maximum retraction, which will depend on the length of the stem (3). As indicated, all the rods will be axially movable and will have means that secure and maintain their position at any height and also allow their recovery to the position of maximum extraction.
- the set of small areas (2) defines a deformable surface on which the mold to be reproduced will be applied.
- the mold to be reproduced consists of the sole of one foot.
- thermoformable material On the forms reproduced on the platform (1) a sheet (7) of thermoformable material is then arranged, figure 4, to which heat is applied, for its thermoforming, at the same time that said sheet is propelled against the shapes of the platform (1).
- the chamber (4) has a mouth or nozzle (8) to which a vacuum source is connected that acts on the lower surface of the sheet (7) through the holes (6).
- the tool from which the shape to be reproduced is obtained is constituted by a surface composed of an infinity of points, allowing to scan the configuration of any body to obtain a surface that can also be modified by varying the coordinates of the small areas (2), for example by means of the corresponding software.
- molds and articles in general of different configurations can be manufactured, starting from the deformable surface of the tool that scans the shapes to be reproduced, allowing then to change the configuration of its points, to introduce corrective concepts, and everything This always ensuring a perfect adaptation of the sheet to be formed on the surfaces reproduced in the tool.
- the coordinates of the different areas (2) which depend on the position of the rods (3) that support them, could be controlled by a computerized mechanical system, functioning in this way as a peripheral of a computer that would control, by means of the corresponding software the position of each area (2).
- the areas (2) may consist or be defined by the cross-section of the stems themselves (3), among which the interstices through which the vacuum would be applied on the surface would be defined bottom of the sheet to conform.
- the small independent areas (2) can be of hexagonal contour, being laterally attached to each other.
- the interstices (6) through which the vacuum will be applied to the sheet (7) to be formed consist of holes (6) that are located at the point of coincidence of the vertices of adjacent independent areas (2).
