Description

Door soul atamborada and mold for your manufacturing.

Object of the invention

The present invention, as expressed by the set forth in this specification, refers to a soul of atamborada door and mold for its manufacture, providing notable advantageous characteristics in the manufacture of this type of souls Door that unlike the solid ones have their hollow interior. They have a sandwich structure formed by a central core which defines the hollow part and two plates or end caps.

It is an object of the invention to be able to form the hollow central core by pressing wood particles or DM and urea formaldehyde glues just like boards conventional, this phase that develops in the mold of manufacturing that the invention proposes.

The object of the invention is also the power build the soul of the door atamborada using plates extremes that complete the sandwich, of the same material as wood particles and pressed glue.

Background of the invention

Currently doors or souls of atamborada doors that include a frame or central core that it can have reinforcement crossbars, which are stuck by both sides of plywood tops bonded with adhesives or queues

There is also a light type of doors atamboradas that include as central core the aforementioned frame perimeter and a honeycomb structure or similar as armor strong enough to at least keep the parallelism of sandwich tops.

On the other hand, as for the mold with which  manufactures the core core of the soul of atamboradas doors that the invention proposes, it is possible to mention the Patent of Invention nº P-200601305 whose applicant is the same as the present invention, in which it is contemplated that souls can be formed of doors with the holes for paneling or glazing, so that material is not wasted, or at least it should not be redirected towards the hoppers of the trainers for reuse, since the door soul is perfectly finished and finished off, only at lack of final rejection and without requiring any machining.

In this Invention Patent cited the mold It is formed by a fixed perimeter frame that follows the contour of the soul of the door, or a multiple of its surface to simultaneously obtain several door souls in the same phase of molding, then separating them by cutting. On a platform horizontal bottom that is vertically scrollable by way of piston using hydraulic cylinders, rest a first frame rectangular adjusted to the dimensions of the frame gap perimeter and that can slide inside, counting in its surface with as many windows as door souls are provided in the mold. These windows receive tightly two seconds racks independent of each other but that are movable telescopically, including these the respective gaps if the there would be paneling or glazing.

The mold is located in a press porches and so that the mobile and hot top plate of the Press closes the mold by contacting the fixed perimeter frame. The holes for paneling or glazing are occupied with blocks metal that remain fixed in flush position with the frame perimeter of the mold.

The first and second or second rectangular frames are hydraulically actuated from below and constitute by themselves the hot bottom plate of the press as they are heat insulated. In the place of the recesses referred to, the blocks that prevent product access on its surface are located and if the door is compact, that is, solid and without paneling or glazing, the second frame is solid and the entire surface will receive the blanket from
chipboard and tail.

In Invention Patent No. P-200602572 which is also from the same applicant for the present invention, improvements in the structure are contemplated previously cited, with which you get an automatism and versatility in the manufacture of different types and models of doors with the same mold. For this it has a framework rectangular with different recesses or windows with the contour of the soul of the door to be manufactured, to simultaneously achieve several fully finished units, defining a composite mold.

In this second Invention Patent cited the blocks that occupy the position of the paneling holes or glazing, are defined by a plurality of elements transverse that can move individually, having Same or different amplitude. The useful surface of the first frame rectangular defines an area where a greater amount of product since it descends to a greater extent than the rest, so that in the pressing one obtains a remarkable greater density than in the rest.

The first and second rectangular racks, as well as the independent intermediate blocks with which they can form the holes for paneling or glazing, they remain supported by vertical rods through a upper horizontal platform that is driven by cylinders lower press hydraulics, this operation is performed once the upper hot plate of the press has covered the mold.

In the Certificate of Addition nº P-200701308 to the main Invention Patent No. P-200602572 recently commented, contemplated some improvements in the mold for the manufacture of door souls that they focus on both the fixed part of the mold and the structure lifting and lowering of the first and second frames for vary the travel stroke depending on the thickness you have To have the soul of the door.

As for the rectangular frame or walls of the mold in which several units can be manufactured in the same phase  pressing, instead of being fixed to manufacture door souls standard, it is divided into two parts: a fixed perimeter exterior to each independent unit and another movable mobile interior telescopically in this one and capable of occupying two positions: a top that stays flush with the outside perimeter to manufacture standard door souls, and another position bottom for manufacturing souls of older doors dimensions in length and width, when descending to the same extent as It is the first rectangular frame to receive more volume of material to be pressed.

It is also contemplated in this Certificate of Addition cited that each independent unit owns in the part exterior fixed perimeter and specifically in its walls longitudinal, mobile strips that can descend in greater than or equal to the extent of the moving inner part, to manufacture door souls of a third width oversize, this area also receiving a greater load of material to be pressed. These last mentioned doors are very used as for the passage in hospitals.

The strips and the inner perimeter part mobile can occupy the lowest position and in turn outdated regarding the first and second frames, to receive more product load and form souls of oversize doors, no more what to do that the hydraulic cylinders that assist them extend or pick up as desired, depending on the order that they receive from the automatic computer control unit that It includes the station. Admission (descent) movements are sequential during the advance of the dispensers that supply the product to be pressed, since when moving to the side download the product contained in the hoppers, which can be DM or wood and glue particles with different densities when they make souls of sandwich doors. When the frame mobile in which the dispenser or dispensers is mounted, comes out from the press, the pressing is done and so when you return to the other side simultaneously takes place the withdrawal of the door souls manufactured, which takes place once the upper press plate and cylinders have been extended bottom of it to take the soul out of the door with respect to the mold.

The dispenser includes a large central hopper with the product to be the central sandwich area of the soul of the door of two densities and two other hoppers smaller sides that contain the product of the layers external of it. At the bottom of the hoppers there are rollers rotating vanes that distribute the product to the sides and also the entire bottom of the hopper is occupied by two bands of transport that move towards the center where there are pallet rollers that are responsible for filling the mold.

Description of the invention

In general, the door soul attached that the invention proposes, together with the mold for its manufacture, it offers a central core that is part of the sandwich of a atamborada door that is built with the mold and who then just attach the covers or side plates to form the soul of the atamborada door, being these covers or plates advantageously of the same particle pressed material of wood agglomerate and urea formaldehyde glues. To this soul The door is only encircled to form the door, both in their faces seen and in the songs thus imitating a noble wood construction chosen as finish.

The hollow central core, from which it takes its name the door or soul of conventional atamborada door, has a structure that can be manufactured by molding, configured as a broken surface of oblique walls in zigzag that define a jagged profile. This teeth does not reach the edges or walls of the mold but it is stuck with respect to the contour of the soul of the door to form, occupying this remaining area with a perimeter frame formed in the same molding phase. The vertices of this jagged surface are truncated to form bands parallel that are coplanar with each other and with the surfaces of the perimeter frame to set up a good settlement and expansion of the gluing surface of the sandwich end caps. He perimeter frame has higher density than the rest and admits machining adjustment to the exact measurements of the door and makes Optimal fastening of hardware with screws.

Moreover, the mold for manufacturing This core of the soul of the door, has a structure basic similar to those of the cited invention patents, since based on the same principle of operation but including some modifications in the structure to adapt to what is intended form, with a fundamental modification in the base or fund of the mold and on the top hot plate of the gantry press that superiorly closes it once loaded with the product of chipboard and tails.

The mold has at least one fixed rectangular frame or perimeter wall in whose interior emptying racks and / or plates are moved telescopically and independently whose free surfaces total the useful surface of the mold and that can move vertically when supported on connected rods to two hydraulic cylinders resting on fixed horizontal bars of the structure of the press. These cylinders carry out their downward stroke to admit the product contained in a dosing hopper that moves horizontally by discharging the product from a single type of particles. The dosing hopper mounted on a carriage moves horizontally while sweeping the surface of the particle mold avoiding scale
unwished.

The pressing action for compression of the product to form the core of the soul of the atamborada door, it  performed by the lifting platform that is operated by the hydraulic press cylinders.

In order to configure the said hollow core, the mold includes a rectangular plate with toothed profile that is defined by a plurality of "V" section grooves of truncated and / or rounded vertices, occupying the central surface of the dimensions of the soul of the door to be manufactured, except for a corresponding perimeter band with the one occupied by two rectangular racks that are independently mobile and thanks to which standard doors can be manufactured atamboradas, or an oversize in width and height, being naturally smooth free surfaces of these racks rectangular.

The top hot plate of the press Porches are equipped with a serrated plate similar to that referred to previously regarding the bottom plate of the press, but its teeth are outdated to the triplet and do not get together to form the broken surface between the teeth wanted.

The plate with toothed mold profile, and the rectangular racks thereof with which the useful surface of the mold, rest on respective four rods verticals arranged in the angular zones and are connected to two hydraulic cylinders for the government and control of your height, descending to a greater extent the perimeter frames that the toothed plate to admit more quantity of product in the  periphery and get the high peripheral density that is intended and with which the fastening of the fittings is achieved by screws as if they were solid wood doors.

Serrated plates have alveoli in communication with existing ducts in metal plates that materialize hot press dishes, ejecting water vapor or hot air that optimizes both pressing and the demoulding

It is also provided that one or both of the toothed plates may include an interruption in their teeth forming two separate toothed surfaces with teeth aligned so that in the compaction phase a stiffening cross member of the core of the atamborada door is formed. The extreme faces of the teeth will be slightly oblique to facilitate demolding. The toothed plates can be exchanged for others adapted to the thickness of the atamborada door to be manufactured. They can also be disassembled if you want to manufacture doors with the same mold
massive.

Description of the preferred embodiment

Referring to the numbering adopted in the figures and especially in relation to figures 1 to 3, we can see the structure of an atamborada door referenced in general with the number (1) and constructed according to the invention, or better still the soul of the door atamborada since it presents sandwich structure that only lacks both sides and the edge perimeter to mimic a solid noble wood door like We had said before.

The central core is referenced with (2) and is the hollow part between the two plates or covers (3).

The central core (2) constitutes by itself the  special novel feature of the invention since it is formed by pressing wood particles and urea formaldehyde glue, like conventional chipboard boards, with particles of certain size and density, such as DM. How We said earlier, the zigzag arrangement according to inclined sections with truncated vertices it is formed by Pressed simply to incorporate the plates in solidarity press plates (4) and (5) hot in the press than in the Pressing phase interconnects without coming together, determining its separation the thickness of the walls of the central core (2), as seen more clearly in figure 7.

The central core (2) in addition to this part hollow atamborada, has a perimeter frame (6) of the dimensions corresponding to standard and oversize doors in width and high, referenced with 6 'since both types of doors can be built with the mold that is recommended, without more than maintaining raised or descending also a perimeter frame whose measurements they correspond, as we will see next, with those of the two door models to be manufactured, these racks being similar to those that we comment on as background of the invention in the Patents of the same applicant of the present invention.

In figures 4 to 6 we see the gantry press (7) with hydraulic cylinders (8) or lower and the upper (9) lower hot plate lower (10) of the press that closes the mold superiorly once it has been filled with the product discharged into it by the dosing hopper (11) that is part of the movable carriage (12) provided with wheels (13) circulating through the views (14) solidarity on the part upper outer walls (15) of the mold (figure 6).

As seen more clearly in Figure 7a and 7b, the toothed plate (4) at the bottom of the mold is fixed to the plate heater (16) of the same dimensions and which is movable down to receive the product to be pressed when descending the four hydraulic cylinders (17) in which it is supported by intermediate vertical rods (18) that connect both elements.

On the other hand, the core's perimeter frame central (2) of the door core, solid and referenced with (6)  naturally forms in the same phase of pressing in the mold and it load with greater quantity of product to obtain greater density than what is required in the atamborada part. For this and as already It is planned in this type of mold as we discussed in the section Background of the invention, as property of the same applicant of the present invention, there is the perimeter frame (19) that contact the heating plate (16) descending more than it by another four hydraulic cylinders (20) and rods intermediate (21).

Compaction does not take place by raising these hydraulic cylinders (17) and (20), but by lifting  of the pushing platform (22) very robust and supported in the vertical strips (23) resting on the horizontal bars (24) linked to the powerful lower hydraulic cylinders (8) from the press.

The push does not directly do the platform (22) but through the push studs (25) and (26) arranged on it and in a position confronted respectively with the iron (16) and perimeter frame (19). As seen in Figure 7b, in the final pressing position the perimeter frame (19) makes up superiorly with the valleys (27) of the plate teeth (4) for that the central core (2) formed is formed. Similarly, at lower the upper plate 10 of the press, the toothed plate (5) partially inserted between the teeth of the toothed plate bottom 4 but the mold closes with flat extensions (28) that make up (by construction) with the flat valleys (29) of the Toothed plate (5).

The push studs (26) are shorter than the (25) because the perimeter frame (19) is taller than the iron (16) and do not make up less, just for this reason.

What is referred to here allows building doors  standard. For those of overmeasure it is why there is a second perimeter frame (30) that plays telescopically on the outside of the first perimeter frame (19) and inside the frame fixed (31) of the walls (15) of the mold. Reference (32) designates an intermediate perimeter insulating surface.

The second perimeter frame (30) is actuated by another four hydraulic cylinders (33) connected through other so many rods (34).

The compaction or pressing is obtained by direct thrust of the push studs (35). In figure 7a it shows obtaining this oversize door where the second frame (30) is always attached to the first frame (19), behaving as a single frame wider and longer than Receive more product.

When standard atamborada doors are manufactured, the second perimeter frame (30) remains up when the extended hydraulic cylinders (33), so that it can be fitted with the fixed mold frame.

Making special reference to the figure now 9, it shows the arrangement in plan of the bands Longitudinal (36) support for all small cylinders (17), (20) and (33), as well as other transverse bands (37) of support and horizontal bars (24) on which the strips support vertical (23) and that are movable by the lower cylinders (8) pressing.

On the other hand, the hopper (11) containing the agglomerated product of wood and tails, which is part of the car Slider (12), is outside the press on either side of the mold during compaction to allow the plate to be lowered top of the press that closes the mold.

When the upper hot plate is lifted (10) and the hydraulic cylinders (20) of the first one are raised frame (19) and those of the second frame (30) where appropriate, the core (2) goes out of the mold and is removed by the car itself slide (12) while filling the mold again to A new pressing. The pusher itself is referenced with (38) and successively moving the four cores central (2) formed in this case. When he goes to the other side of the press produces a new press and then is the other pusher (38) on the opposite side of the car (12) who removes it, while all the units of the mold are filled again.

Figures 10 to 12 show the geometry of the sliding carriage (12) with the large hopper (11) container of the product. As it progresses it discharges perfectly dosed with the three central rotating rollers (39) provided with vanes and fed superiorly by the two endless bands (40). exist two other conveyors (41), in this case pallets (42) (see Figure 11) that help to pour more product towards sides that is where it is most needed to form the solid frame (6) and high core density (2).

Figure 12 shows the lower floor where two cleaning rollers (43) and (44) are distinguished in both ends of the sliding carriage (12). The most internal (44) are arranged obliquely to optimize the sweeping and smoothing of the layer poured into the mold. The outer rollers (43) are more long and sweep the horizontal surface that will contact the upper hot plate of the press avoiding scale.

At least the lower toothed plate (4) (figures 7a and 7b) has alveoli (45) in communication with collectors (45 ') water vapor distribution or hot air that optimizes both pressing and demolding. The collector channels (45 ') are practiced on the same toothed plate (4) remaining in communication with the channels (46) and output perforations made in the heating plate (16) which also has others conduits or galleries (47) of thermal fluid circulation, since remember that this plate or plate (16), like the perimeter racks behave together as the dish Hot bottom of the press.

It should also be noted that as observed in Figures 4 and 5, the remaining product that is swept by the cleaning rollers (43) and (44) of the movable carriage (12), is collected in one or another channel (48) configured on the sides of the mold and driven for recovery using an auger (49) arranged at the bottom of the respective channel (48).
