Definitions
- the present invention relates to a vertical molding machine of specks, which has been perfected in certain aspects of it to achieve an increase in production, by reduction of the work cycle time, as well as to avoid possible erosions, deformations or crushing of the specks that lead to an improvement in the quality of the pieces obtained.
- the molding machines of motorcycles basically comprise a molding chamber, fed by a sand hopper established in the upper part, said chamber being closed by a sliding and tilting front plate and by a rear plate provided at one end of an extractor piston, performing the compaction of the sand by opposing pressure of both dishes.
- specks that make up two half-molds and that, with the help of the extractor piston, are extracted from the molding chamber and are attached and aligned with each other forming a row that will move, step by step , along the corresponding work stations, passing through a station in which the filling of the molds with the broth takes place and continue advancing while the cooling of the piece occurs and then go on to the subsequent processes.
- the successive specks that make up the row determine the molds in which the casting of the broth occurs and, therefore, must be perfectly aligned and kept attached and closed with a certain pressure that is capable of withstanding the broth pressure.
- the movement of the row of motes throughout the installation is produced by pushing the extractor piston over the last speck produced, so that the extractor piston not only positions the speck attached at the end of the speck row but which presses on it causing the movement and advance of the entire row.
- the extractor piston causes the entire row to advance one step, so that in the successive cycles, the row of motes moves forward, step by step, throughout installation.
- Installations are also known in which the displacement and advancement of the motes throughout the installation is produced initially by the thrust of the piston and subsequently by the actuation of a transport system.
- An installation of this type is described for example in European Patent No. 0 693 337 in which a transport system is provided which is constituted by a series of longitudinal bars that can advance or back off approaching or moving away from the molding station.
- the extractor piston pushes the last speck obtained until it is placed on the bars of the conveyor system, leaving it attached to the row of specks formed previously, the transport system being the one that, from this moment, produces the advance, step by step, of the row of specks.
- the operation of the extractor piston depends on the position and operating cycle of the transport system, so it cannot push the speck out of the station of molding until the transport system is not in the position of receiving motes. In this way, the cycle or operation of the molding station is conditioned by the movement of the row of specks and, therefore, any stop or interruption in the subsequent stations will influence the performance of the molding station.
- the conveyor system is constituted by longitudinal bars that can move on rollers causing the row of motes to advance one step, after which some lateral clamps, independent of the longitudinal bars, firmly hold the last speck while the longitudinal bars of the conveyor until reaching the end of the molding station, so that the extractor piston can place another speck on the conveyor.
- the motes are subject to friction against the bars that constitute the conveyor system, so that in this case there will also be wear that deteriorates the motes and can influence the quality of the pieces obtained.
- the lateral clamps must be applied on the last speck with great pressure since they must avoid the retraction of the entire row of specks when the conveyor bars recede, thus causing crushing and deformation on this last speck that also negatively influences the quality of the pieces obtained.
- the accompaniment or thrust of the extractor piston during the initial movement of the speck until it is deposited on the conveyor system requires a perfect synchronization between the movements of the transport system and the extractor piston, since otherwise light can occur differences in position and / or speed that would generate friction between the motes, which in turn would cause erosions in the sand mold that will later result in defects in the piece.
- the vertical molding machine that is recommended has been designed to solve the aforementioned problem, based on the fact that the movement of the speck, pushed by the extractor piston is completely independent of the movement of the speck row, that is, that the Speck thrust by the extractor piston is performed depending on the molding sequence and not depending on the movement of the transport system.
- the extractor piston places the speck in an intermediate position that is defined at the final end of the base plate of the molding station and that is not part of the transport system, so the extractor piston does not intervene at any time in the advance of the row of motes in their displacement along the installation, that is, the row of motes does not advance by the thrust of the last speck extracted by the extractor piston but by the action of a independent conveyor system
- the piston deposits it in the intermediate position and withdraws to begin a new molding cycle, the transport system being the one takes care of picking up the speck and causing its advance integrated into the row of specks.
- the extractor piston takes the speck to an intermediate position or station, defined at the end of the base plate, prolonging the molding chamber, and with which the system is sandwiched at certain times. of transport, in such a way that the speck is deposited by the extractor piston in said intermediate position, without exerting pressure on the row of motes, position in which it is collected and removed by the transport system and advance of motes that, to from that position it will be in charge of the movement of the row of motes throughout the installation.
- the end of the base plate is formed by a series of projections, which determine a kind of comb, dimensionally and formally complementary to a series of galloping bars that are part of the transport system and that, by the appropriate operating sequence, interleaved with the base plate to remove the speck that had left the extractor piston and advance the entire row of specks.
- the galloping bar system produces the advance of the row of specks without friction or thrusting on the same, so that the quality of the pieces obtained is improved.
- the molding station becomes independent of the movements of the transport system so that, although it is not in the collection position or intermediate position, the extractor piston can remove the mote from the molding chamber without interrupting its work cycle, positioning it at the end of the motherboard and backing to begin a new molding cycle.
- both movements will be synchronized so that when the extractor piston deposits the speck in the intermediate position, the conveyor is already interspersed with it and the speck is attached at the end of the row of specks, then producing the joint movement of the entire row of motes using the conveyor system.
- the vertical molding machine has a series of advantages over conventional ones, which can be summarized as follows:
- FIGS 1 to 6. They show the different phases or operating sequences of the vertical molding machine object of the present invention.
- FIG 1 the initial phase of work is shown with a speck obtained in the molding chamber and with the front plate displaced and tilted to allow the extraction of said speck.
- the transport system is in position to remove the speck once the extractor piston positions it in the intermediate zone.
- Figure 2 shows the thrust of the speck by the corresponding piston, which places it in the intermediate position defined by the interleaving between the base plate of the molding station and the bars of the transport station.
- Figure 3 shows the same position of the speck but in this case with the jaws of the transport system laterally holding the last speck obtained.
- the advance bars or strips have risen and are the ones that support the complete row of specks, including the last speck, while the fixed bars or strips are in a low position, that is, without contact with the motes row.
- Figure 4 shows the next phase in the that the piston has receded and the front plate has been placed in the closed position of the molding chamber, without the transport system having yet produced the advance of the row of specks.
- Figure 5 shows the movement of the bars or strips of advance, with the jaws holding the last speck, causing the displacement, without friction, of the entire row of specks.
- Figure 6 shows the recoil of the advance strips of the transport system, having previously produced the release of the lateral jaws and the rise of the fixed strips, so that the row of specks is supported on the fixed strips while the mobile strips go back down until they are interspersed with the base plate of the molding station.
- Figure 7 shows, finally, a schematic detail in plan of the end of the base plate of the molding machine, in the form of comb, and of the bars or fixed and forward strips of the transport system of the row of specks , defining an interleaving between the strips of advance and the base plate that constitutes precisely the station or intermediate zone of delivery and collection of the specks.
- the machine of the invention includes a molding station (1) in which a chamber (2) is established in which the molding of the speck (3) is carried out with the sand contained in a hopper (4) established in the part higher.
- the chamber (2) is closed at its front end by a front plate (5) that is movable and tiltable around an axis (6) to enable the extraction and advance of the obtained speck (3) towards the row of specks (3 ') located on the corresponding conveyor (7), while at the rear the chamber (2) is closed by a rear plate (8) associated with an extractor piston (9).
- Said molding station (1) also includes the corresponding base plate (10) through which the speck (3) is moved from the chamber (2), an intermediate position being defined at the end of the base plate (10), interspersed, at certain times, with a conveyor (7) constituted by a series of horizontal bars or strips on which the row of motes rests and that produce the displacement of it along the whole installation, without intervention of the extractor piston ( 9).
- the last speck produced in the molding chamber (1) is pushed by the extractor piston (9) until it is deposited in the intermediate position, the speck resting on the end of the base plate (10), regardless of whether the system bars of transport are interspersed or not with the motherboard. From this moment, the extractor piston (9) can go back to start a new cycle, being the transport system (7) the one that will be in charge of moving, both the last speck (3) deposited in the intermediate position and the row of previous specks (3 '), throughout the installation, without any intervention of the extractor piston (9).
- the end of the base plate has projections (12), determining a kind of comb, dimensional and formally complementary to bars or strips of progress (17) of the transport system (7).
- These bars or strips of advance (17) can move slightly in the vertical direction and also in the direction of forward / reverse, thus behaving like a system of galloping bars, in such a way that they can recede until they are intercalated with the base plate (10), in the intermediate position, and collect the speck deposited by the extractor piston (9).
- the bars (17) advance causing the displacement of the entire row of specks (3 '), all operations having been carried out without the motions suffering any pressure, crushing or friction that may influence the final quality of the pieces .
- the transport system also incorporates fixed strips (16) that are provided only with upward / downward movement that are sometimes used to support the row of specks (3 '), mainly when the forward strips (17) go back to the intermediate position to collect the last speck produced.
- the machine is completed with lateral jaws (15) that hold, with a slight pressure, the last speck during the extraction or collection by the transport system (7), with the sole purpose of preventing them from being left behind due to the inertia or the possible suction that the extractor piston (9) can exert in its recoil.
- the conveyor system (7) is in position of collecting the speck, that is, the fixed strips (16) are in their highest position and the advancing strips (17) in a low position overlapping with the comb-shaped end of the base plate (10 ) jointly attached to the molding chamber. In this position, the row of specks (3 ') is supported exclusively on the fixed strips (16). This position corresponds to figure 1.
- the extractor piston (9) removes the mote from the molding chamber (2) and deposits it in the defined intermediate position between the comb-shaped end of the base plate (10) and the feed strips (17), leaving the speck (3) positioned exclusively on the end of the base plate (10) since the advance strips are in their lowest position. This position corresponds to figure 2.
- the speck (3) positioned by the extractor piston (9) in the intermediate position can be removed by the galloping bar system without the specks suffering any pressure or friction.
