Definitions

  • the present invention generally belongs to the field of casting production using breakable mold materials.
  • the object of the invention is a mold string conveyor having one or more gravity-driven mold extraction devices allowing for the extraction of molds in different positions along the conveyor.
  • Casting manufacture is often carried out using breakable molds produced in a mold station.
  • the molds are then transported to a pouring station where each mold cavity, which usually corresponds to the space between two adjacent mold parts in a mold string, is filled with the melt for forming a part.
  • each mold cavity which usually corresponds to the space between two adjacent mold parts in a mold string
  • the castings are extracted from within the molds at an end of the mold string conveyor.
  • the molds are then transformed into mold raw material again for the subsequent production of new molds.
  • the molds form a mold string and are advanced stepwise by means a mold string conveyor.
  • the molding chamber, the pouring station, as well as any additional device provided along the mold string conveyor operate intermittently in synchronism with the stepwise advancement of the molds along the mold string conveyor.
  • mold integrity must be assured until the castings are sufficiently cooled for break-out from the molds.
  • the mold string conveyor must ensure that no shifting, distortion or displacement of molds occurs.
  • a first high-precision type of transport system is employed for the first stretch of the mold string conveyor.
  • a less precise, lighter transport system is used for the second stretch of the mold string conveyor.
  • High-precision transport systems are, e.g. movable longitudinal side rails and walking beam, while an example of a low-precision transport system is an endless belt conveyor. These transport systems are known in the art, see, e.g. document US 7,032,641 .
  • molds must be extracted before reaching the end the mold string conveyor, e.g. from a stretch of the conveyor between the pouring station and the extraction station where cooling of the castings takes place. Indeed, in certain cases it is interesting to extract molds before they are completely cool for research purposes in connection with the cooling process. Occasionally, faulty molds or molds containing faulty castings must be extracted from a specific position along the mold string. In any case, there are a number of systems specifically designed for extracting the castings from within the mold string.
  • Document US 3,659,701 discloses different mold extraction locations via movable conveyors.
  • the transport surface comprises spaced rails and movable conveyors are positioned in line by telescoping the corresponding rails at their ends. This system is compatible with the abovementioned high-precision, longitudinal side rail transport system.
  • Document EP 1,752,239 discloses a process for removing the casting from the mold by dissolving the binder in the mold.
  • Patent documents FR 1486510 and JP S 5638304 B further disclose a mold string conveyor with a mold extraction device, wherein the mold extraction is provided with a trapdoor.
  • the mold string conveyor of the present invention solves the aforementioned drawbacks by comprising one or more mold extraction devices allowing for the extraction of particular molds or for the continuous extraction of molds at certain locations from the mold string.
  • a mold string conveyor is configured for providing support for a mold string while stepwise displacing said mold string forward along a displacement path.
  • the mold string conveyor of the invention further comprises at least one extraction device, where the extraction device comprises an inferior trapdoor provided along the displacement path between a first stretch and an adjacent, second stretch of said mold string conveyor. Therefore, any mold located on the trapdoor falls down out of the mold string when said trapdoor is in open position.
  • the mold extraction device further comprises trapdoor mold conveying means configured for stepwise displacing the portion of the mold string located on the trapdoor forward along the displacement path in synchronism with first mold string conveying means of the first stretch of the mold string conveyor and second mold string conveying means of the second stretch of the mold string conveyor.
  • the trapdoor comprises a plate horizontally hinged to an end of the first stretch of the mold string conveyor in perpendicular to the direction of the displacement path. Therefore, the trapdoor alternates between a closed position where the plate is oriented horizontally for providing support to a portion of the mold string located on the trapdoor, and an open position where the plate is inclined downwards for allowing molds in the portion of the mold string located on the trapdoor to fall down.
  • the trapdoor comprises a first horizontal portion providing support for the mold string in a gap between the end of the plate when in the horizontal position and the end of the second stretch of the mold string conveyor thus minimizing the gap between the end of the following stretch of the mold string conveyor and the trapdoor.
  • This embodiment is advantageous in that the horizontal portions avoid any mold raw material from falling down through the gap between the trapdoor and the ends of the following stretch of the mold conveyor.
  • the molds are commonly made of small grain size particles, so in case no horizontal portions were present the mold raw material could fall through the gap distorting the layout of the mold with the risk of losing its integrity.
  • the mold string conveyor of the invention comprises an actuation means causing the trapdoor to alternate between the open position and the closed position.
  • the actuation means could be of any type, such as e.g. based on electric motors or the like.
  • the actuation means comprise pneumatic or hydraulic cylinders connected to the plate.
  • the mold string conveyor further comprises a shield plate extending essentially downwards from an end of the second stretch of the mold string conveyor for guiding the falling molds when the trapdoor is in the open position.
  • the shield plate thus ensures that molds falling downwards through the trapdoor land on a predetermined desired position under the mold string conveyor.
  • the shield plate further ensures that the falling molds do not hit any part of the mold string conveyor located below, such as support legs, beams, or endless belt rotating cylinders.
  • the mold string conveyor further comprises a receiving chute situated under the trapdoor for receiving the falling molds when the trapdoor is in the open position.
  • the receiving chute could be of any kind provided it receives the falling molds when the trapdoor opens.
  • the chute may additionally comprise a vibrating horizontal grid for breaking up the molds into raw mold material, thus releasing castings embedded inside the molds.
  • the falling molds land in the chute and the vibrating horizontal grid breaks up the molds and converts them into raw material, e.g. sand.
  • the mold raw material falls down through the vibrating grid, while castings present inside the molds accumulate on the horizontal grid.
  • the receiving chute is connected to a dedicated casting conveyor configured for transporting away the castings.
  • the mold string conveyor further comprises a lower conveyor situated under the receiving vibrating horizontal grid for receiving the raw mold material that drops down through the vibrating horizontal grid.
  • the raw mold material e.g. sand
  • the castings and the molds can be automatically separated and transported to respective stations.
  • the trapdoor mold conveying means could be of any type, it preferably comprises movable longitudinal side rails mechanically synchronized with the first mold string conveying means and the second mold string conveying means.
  • the trapdoor movable longitudinal side rails are prolongations of the movable longitudinal side rails of the first mold string conveying means. That is, the trapdoor movable longitudinal side rails can be produced merely by providing longer movable longitudinal side rails in the first stretch of the mold string conveyor. Synchronization between them is thus guaranteed without needing to perform any additional mechanical connection.
  • the trapdoor movable longitudinal side rails comprise dedicated side rails. Therefore, in this embodiment an additional mechanism is provided for stepwise transporting forward the portion of the mold string situated on the trapdoor. This additional mechanism is mechanically connected to the mold string conveying means of the first and second stretch of the mold conveyor for ensuring a suitable synchronism therebetween.
  • the mold string conveyor of the invention further comprises a second horizontal portion providing support for the mold string in a gap between the end of the first stretch of the mold string conveyor and the trapdoor.
  • this second horizontal portion ensures that no raw material, e.g. sand, falls down through the gap present between the trapdoor and the first stretch of the conveyor.
  • the mold string conveyor comprises detection means configured for detecting the position of a particular mold along the mold string conveyor and control means configured for opening the trapdoor when said particular mold is located on the trapdoor.
  • Figs. 1 shows a prior art mold string conveyor (200) having a first stretch with movable longitudinal side rails and a second stretch with endless belt conveyor.
  • the movable longitudinal side rails mechanism of the first stretch comprises a plurality of lower longitudinal plates (210) providing support for the mold string (300) along the displacement direction (DD).
  • the mold string (300) thus slides on these plates (210) it is are forced to move forward towards the second stretch.
  • Movable longitudinal side rails (220) are provided at both sides of the mold string (300) supported by the lower plates (210). The movable longitudinal side rails (220) sequentially grip the mold string (300), displaces the mold string (300) forward a predetermined distance, then releases the mold string (300), and finally returns to its original position. Fig.
  • FIG. 1a shows a first situation where the movable longitudinal side rails (220), in a forward position, are still gripping the mold string (300) after having advanced the predetermined distance. Then, as shown in Fig. 1b , the movable longitudinal side rails (220) move outwards, i.e. horizontally in perpendicular to the displacement direction (DD). The mold string (300) is thus released. In a subsequent step shown in Fig. 1c , the movable longitudinal side rails (220) move backwards, i.e. in a direction opposite the displacement direction (DD), therefore returning to an original back position. Since the mold string (300) is not gripped by the movable longitudinal side rails (220), it remains in place during this step. Fig.
  • FIG. 1d shows the movable longitudinal side rails (220) again moving horizontally inwards in perpendicular to the displacement direction (DD), thus gripping the mold string (300) again.
  • Fig. 1e shows the movable longitudinal side rails (220) move forward the predetermined distance.
  • the mold string (300), gripped by the movable longitudinal side rails (220), is displaced forward the predetermined distance (in the figure the distance corresponding to twice the molds thickness) along the displacement direction (DD). This mechanism therefore ensures that the mold string (300) moves stepwise forward along the first stretch of the mold string conveyor (200).
  • the second stretch of the mold string conveyor (200) is based on an endless belt mechanism that moves stepwise in synchronization with the movable longitudinal side rail conveyor disclosed above. More particularly, the movable longitudinal side rails (220) of the first stretch are mechanically connected with side beams (230) of the second stretch by means of a connection bar (250) to assure full synchronism.
  • the side beams (230) are provided in parallel to the displacement direction (DD) at both sides of an endless belt (240) providing support for the mold string (300).
  • the side beams (230) do not move outwards or inwards in perpendicular to the displacement direction (DD).
  • a known mechanism allows for the side beams (230) to selectively grip the side portions of the endless belt (240). When the side beams (230) move forward, as shown in Fig. 1e , they grip the endless belt (240) causing it to advance the predetermined direction disclosed above. When the side beams (230) move backwards, as shown in Fig. 1c , they do not grip the endless belt (240), and therefore it remains in place.
  • Figs. 2 and 3 show a first example of the mold string conveyor (1) of the present invention.
  • the mold string conveyor (1) is formed by a first stretch (11) having first mold string conveying means based on movable longitudinal side rails (111) and a second stretch (12) having second mold string conveying means based on an endless belt (121).
  • the actuation and synchronization mechanism driving these mold conveying means is similar to that disclosed above in connection with Fig. 1 .
  • movable longitudinal side rails (111) are provided at both sides of the mold string (300) in parallel to the displacement direction (DD).
  • the movable longitudinal side rails (111) are driven by a mechanism comprising a pneumatic cylinder (112) that causes them to follow the movement cycle disclosed above in connection with Fig. 1 : the movable longitudinal side rails (111) grip the mold string (300), then move forward the predetermined direction, then open outwards for releasing the mold string (300), and finally return back to the initial position.
  • the movable longitudinal side rails (111) are gripping the mold string (300) while in the back position (as in the situation shown in Fig. 1d ).
  • the mold string (300) is resting on an endless belt (121).
  • Side beams (122) are provided at both sides of the endless belt (121).
  • the side beams (122) are mechanically connected to the movable longitudinal side rails (111), such that the movable longitudinal side rails (111) cause the side beams (122) to move alternatively forward and backward along the displacement direction (DD).
  • a known mechanism allows for the side beams (122) to selectively grip the side portion of the endless belt (121).
  • the side beams (122) are caused to also move forward while gripping the endless belt (121).
  • the mold string (300) thus synchronously moves forward the predetermined direction both in the first stretch (11) and in the second stretch (12) of the conveyor (1).
  • the side beams (122) are caused to also move backwards.
  • the side beams (122) do not grip the endless belt (121) during the backward displacement.
  • the mold string (300) thus does not move during this step.
  • This conveyor (1) further comprises an extraction device comprising a trapdoor (2).
  • the trapdoor (2) is provided between the first stretch (11) and the second stretch (12).
  • the trapdoor (2) comprises a plate (21) hinged to an end of the first stretch (11) of the conveyor (1) along a horizontal direction in perpendicular to the displacement direction (DD).
  • the plate (21) can therefore adopt a closed position where it is horizontal, as shown in Fig. 2 , and an open position where it is oriented essentially downwards, as shown in Fig. 3 . In the closed position, the plate (21) is flush with the lower horizontal plates (not shown in Figs 2-3 , but disclosed in connection with Fig.
  • the mold string (300) moves normally supported by the plate (21) when in the horizontal position.
  • the trapdoor (2) opens, the plate (21) opens downwards, and any mold (310) resting on the plate (21) when in the horizontal position will fall down.
  • the trapdoor (2) opens and closes driven by a pneumatic cylinder (22) having an actuation end connected to the plate (21) and a fixed end connected to a portion of the structural support of the conveyor (1) or to the floor.
  • the mold extraction device further comprises mold string conveying means for ensuring that molds (310) resting on the plate (21) when in the horizontal position move normally forward along with the rest of the mold string (300).
  • the trapdoor mold string conveying means comprises movable longitudinal side rails (6). These trapdoor movable longitudinal side rails (6) are merely a prolongation of the movable longitudinal side rails (111) of the first stretch (11) of the conveyor (1). Therefore, synchronization between them is ensured without the need to implement any additional synchronization mechanism.
  • the conveyor (1) additionally comprises a shield plate (3) extending essentially downwards from an end of the second stretch (12) of the conveyor (1).
  • the shield plate (3) ensures that they don't hit any of the cylinders of the endless belt (121).
  • the shield plate (3) further directs the falling molds (310) towards a receiving chute (4).
  • the trapdoor (2) further comprises an first horizontal portion (31) closing a gap between an end of the endless belt (121) of the second stretch (11) and a free end of the plate (21), thus avoiding deformations in the molds (see Fig. 6 ).
  • the receiving chute (4) is configured as a container for collecting the molds (310) extracted from the mold string (300) through the trapdoor (2).
  • the base of the receiving chute (4) comprises a vibrating horizontal grid (not shown) that causes the molds (310) to break up, thus turning into mold raw material.
  • the mold raw material falls through the grid and is collected by a lower conveyor (5) situated under the receiving chute (4).
  • the lower conveyor (5) is parallel to the mold string conveyor (1), ending in a machine where the mold raw material along with mold raw material from the mold string (300) are thoroughly broken up into small grain size mold raw material for the subsequent production of new molds.
  • a dedicated casting conveyor (not shown) is provided for extracting castings released from the molds inside the receiving chute (4) and for transporting them towards a subsequent station.
  • Figs. 4 and 5 show a second example of the mold string conveyor (1) of the present invention where the first and second mold string conveying means of the first stretch (11) and the second stretch (12) of the conveyor (1) comprise endless belts (121).
  • the mold extraction device comprises a trapdoor (2) provided between the first stretch (11) and the second stretch (12) of the conveyor (1).
  • a shield plate (3) directs the falling molds (310) towards the receiving chute (4) and ensures that no cylinder of the endless belt (121) is hit.
  • the trapdoor (2) further comprises a first horizontal portion (31) closing a gap between the end of the second stretch (12) of the conveyor (1) and the free end of the trapdoor plate (21).
