Definitions
- This invention generally regards aluminium casting technology and refers to the gravity mold casting and low pressure casting processes, which use specific molds and dies mounted onto casting benches and low-pressure casting machines respectively for the two different technologies .
- Typical examples of these technologies are those used, not exclusively, .to cast engine cylinders heads.
- the low-pressure casting machine is also characterizied by using a modern system to carry out the casting process from the lower part of the die.
- the casting expulsion area is always in the upper part. This expulsion is carried out using a vertically sliding ejectors plate, which is rather hanged over as it excludes the possibility of operating on the die axis directly from vertically above, particularly affecting the core making device, which can only operate laterally, making it a very complicated device.
- the molten metal is introduced into the mold from above using a ladel operated by a casting robot, usually suspended from an overhanging beam, which is often also used for the automation of the core making device and the casting pick-up device.
- the molten metal is taken by the robot from a nearby furnace and poured through a basin into vertical and horizontal casting channel runners in the mold until the figure and the open feeding risers are full .
- the risers attract any slag in the molten metal, which floats into it, and are used to feed the casting as the cooled metal shrinks and to release the gases contained in the molten metal, as well any further gases which develop when the metal comes into contact with the cores, making the best possible casting in terms of mechanical characteristics, despite some collateral disadvantages .
- the molds and the casting benches are usually placed on the ground, in pairs or multiples of pairs, to facilitate the automation of the process.
- the whole system can be mounted onto large, slow-moving turntables called carrousel conveyors so that the casting point is maintained stable as regards to the rotating movement.
- All the molds are filled by a single robot placed on a fixed station of the carrousel on which are fitted the benches and the molds.
- the die comes into direct contact with the furnace, as the furnace, situated under the machine, is raised in order to make contact with the die.
- the lid of the furnace is equipped with one or more vertical pipes which are immersed in the "bath” of molten metal. The top of these pipes comes into direct contact with the injection inlets applied to the drag of the die.
- the pressure of the air presses on the "bath” and forces the metal upwards into the mould through the immersed pipes and the injection inlets applied to the drag of the die until it is full.
- This die doesn't need any feeding risers as their function is performed, by the pressure of the air exercised on the molten metal .
- the upper part of the die is closed by a metal male which, besides determining the casting figure, prevents the metal forced upwards by the low pressure from coming out of the die.
- the air pressure is maintained for a short time, until the molten metal begins to solidify, facilitated by coolers in the die and, in particular, on the injection inlets, which contribute to the rapid solidification of the metal in the upper part of the inlet hole, preventing the molten metal injected into the die from returning, due to the force of gravity, into the furnace when the air pressure is released and allowing the molten metal contained in the casting pipes to return into the "bath" , avoiding its solidification.
- the solidified metal in the upper part of the injection inlet is then expelled together with the casting.
- the main aim of this invention is to add a new type of casting technology to those that already exist.
- the new technology will be known as "combined” technology and will be capable of fully exploiting the advantages that obtainable by gravity and low-pressure casting technologies .
- Another aim of the invention is to present a new casting bench capable of holding both molds and dies and of enabling the easy passage from one casting technique to the other. For this reason, the tool that determines the outer figure of the casting, currently called mold or die depending on the technology used, will be referred to herein exclusively as mold.
- Another aim of the invention is that of enabling the operator to thoroughly clean the mold after extracting the casting and, where necessary, to quickly repaint the parts of the figure of the mold on the bench, with a very short production interval, which, being hot, facilitate the solidification of the paint, without preheating the mold off the production line and so extending the production time.
- Another aim of the invention is to present a single standardised casting bench which always enables the expulsion of the casting from the bottom of the mold, even when, in the case of low-pressure casting or "combined" technology, the holding or maintenance furnace is placed under the mold.
- Another aim of the invention is to present a support which can be applied to the top of all the molds, for all casting technologies, equipped with a vacuum chamber for connection to a vacuum system to remove fumes and gases from the mold during casting.
- Another aim of the invention is to transfer some of the parts of the mold which do not form the casting figure, known as frames, from the mold to the casting bench, so that they are built just once with the bench and, being standardised, are not copied to provide the number of molds needed for production and for the various kinds of castings and casting technologies.
- Another aim of the invention is to present a casting bench equipped with a lower structure the height of which may be adapted to suit the casting process used. In particular, in the case of gravity casting, where there is no furnace underneath the mold, the bench may be lowered for mounting on carrousels. The same standard bench for use on carrousels may also be placed directly on the ground when using the traditional gravity casting system, but with smaller, lighter and cheaper molds.
- Another aim of the invention is to enable the transformation of a mold for gravity casting technology for use in low-pressure technology, constructing a metal upper male and related accessories, which will replace the core which usually forms the risers and the upper figure; consequently the mold will have no risers. It will be easy to revert to gravity casting using "combined" technology, setting aside the upper male and using the core again.
- Yet another aim of the invention is to provide a casting bench with split, overlapping slides carriers for core making reasons, on both slides carriers (right/left) or on just one side. The opening and closing movement of the two halves of the slides carriers will take place independently by way of hydraulic cylinders or simultaneously (parallel movement) , when split movement is not required.
- the slides carriers will be supplied in a single unit .
- a consequence of the invention is the elimination of the casting robot for gravity casting molds, placed on the ground, when these are transformed for low-pressure casting or "combined" technology.
- the entry of the metal into the mold will take place from the underlying furnace and consequently the movement of the casting robot on the beam, usually positioned above the mold, will also be eliminated where the beam is already occupied by the core making device to place the cores in the mold and the casting pick-up device, facilitating the movement of the latter.
- This invention presents a standardised conformation of the toolings used for the production of a casting for engine cylinders heads or other compatible castings, with a single standard casting bench for the new molds presented here, or those which already exist and are modified for this purpose, . for all the casting technologies referred to above, with inferior expulsion of the casting and with a tilting arm for moving all the parts of the mold situated in the upper part.
- the molds for the following technologies will be mounted on the standard bench: - molds for low-pressure casting technology with metal upper male; - molds for "combined” technology, or with low- pressure casting and gravity feeding through risers created in the upper core; - molds for “combined” technology with low-pressure casting and gravity feeding through risers created in the metal cope; - molds for traditional gravity casting technology with upper casting basin and gravity feeding through risers created in the upper core; - molds for traditional gravity casting technology with upper casting basin and gravity feeding through risers created in the metal cope.
- the casting procedure according to this invention envisages the concentration of all the toolings in the same production space, with the use of a single casting bench for all casting technologies and with the same holding furnace, both for molds with low-pressure casting and molds with low-pressure casting but with gravity feeding through risers, by means of use of the new casting technology, known as "combined" technology.
- the new casting technology known as “combined” technology.
- the mold is formed as follows: drag, slides, fixed heads applied to the drag, mobile heads, where fitted, which slide in the fixed heads, lower ejectors plate and, depending on the technology used, male, cope or simply a vacuum upper lid plate.
- the male and cope will also be mounted on a vacuum plate which will then be mounted on a support.
- the casting bench will be given slides carriers, the base plate, all the guides and sliding gibs. Consequently, the molds will be cheaper to make, will weigh much less and will be smaller, enabling savings during transportation over long distances, within the factory and during storage.
- the casting bench and the mold will be managed by the same computer that currently manages the furnace and the low-pressure casting technology machine, so the bench will replace the machine, becoming standard for all technologies.
- the bench will be strong, properly cooled and insulated, so that it is not affected by thermal dilation.
- the mold will be free to dilate as necessary and to reach the right thermal balance with the addition of coolers governed by the computer.
- the operations for clamping the drag, hooking the slides on the casting bench and fastening the ejectors plate will take place quickly by way of hydraulic cylinders (jacks) .
- the mobile heads, where fitted, will be moved by hydraulic cylinders and will be hooked up manually but quickly by way of a shot sleeve which blocks the mushroom of the head with that of the hydraulic cylinder.
- This process will be called “combined” technology.
- the mold will be fitted with a support with the plate covering the entire riser area to contain the thrust of the metal .
- This plate will also act as a vacuum plate, being mounted on the support with vacuum chamber.
- This support is applied and moved by a tilting arm hinged to the top of the bench.
- the support will be connected to a vacuum device which will suck fumes and gases produced by the molten metal and from contact with the cores through the plate.
- the vacuum plate with the metal male or cope will be equipped with filters in line with the upper core risers or the figure risers to allow the evacuation of fumes and gases, blocking the passage of the molten metal. Therefore, the support and everything applied to it are an integrated part of the mold.
- - support with vacuum plate which did not previously exist and is therefore part of the new design, for use in the new "combined” technology (low-pressure casting - gravity feeding through risers) , both to vacuum fumes and gases, and to seal the upper surface of the mold and the cores that generate the feeding risers, to contrast and block the thrust of the metal of the casting feeding risers, preventing the molten metal from overflowing during the casting phase;
- - support as above with vacuum plate and fitted metal cope used in the new "combined” technology to seal the upper surface of the mold in line with the risers .
- the aforementioned cope acts as the male which generates the upper figure of the casting and, together with the slides, the risers that feed the casting using the gravity technology; - support and vacuum plate to which a metal male is applied, used in low-pressure casting technology to generate the upper figure of the casting without the risers.
- the support with vacuum plate, the support with vacuum plate and cope and also the support with vacuum plate and upper male, applied to the three technologies are all made with a plate to which filters are applied in line with the risers and the figure. These filters converge in a fume and gas vacuum chamber, created in the support, which will be connected to a vacuum device.
- This vacuum " is destined to improve the quality of the castings with all the technologies, including low-pressure casting technology, inasmuch as, with appropriate vent slot on the sides of the male and internal passages , it is possible to get close to the cores to vacuum fumes and gases, the majority of which currently remain inside the cast, generating widespread porosity.
- the introduction of the new fume and gas vacuum system to all the technologies, including low-pressure casting, will contribute to improving the quality of castings and the working environment, regardless of the technology used.
- the new mold used in the "combined" technology process will have no casting basin and no vertical casting channels, although the new project of mold provides for their presence without moving on to the final phase of construction .
- the casting will be extracted using a standard device inserted into the base plate of the bench and made up of a plate holder onto which the ejectors plate with which all molds are equipped will be quickly fastened using hydraulic cylinders (jacks) .
- hydraulic cylinders jacks
- the vertical casting channels in the lower part will be plugged.
- Both new and existing molds will be fitted with injection inlets in the drag, envisaging a fast cooling technique like that used in low-pressure technology to solidify the molten metal and avoid the return of the liquid metal into the furnace due to the force of gravity when the air pressure is cut off.
- This new casting technique eliminates the disadvantages of gravity casting deriving from taking slag from the furnace and oxidisation, maintaining advantages such as discharging the same slag and gases and fumes that develop during the casting process through the risers, which are now sucked out by the new device-s illustrated and claimed .
- the metal male envisaged in molds for low-pressure casting which is replaced by a core or a metal cope in the gravity casting procedure, all of which are managed by the same tilting arm on the bench, it is possible to easily transform a gravity casting mold into a low-pressure casting mold by adding injection inlets in the drag (lower part of the mold) , and from lower-pressure to gravity by removing the male and replacing it with a core.
- the automation of a gravity casting line of the current type envisages the use of a core making device a casting robot and a device for picking up the casting. All movement often takes place on the same beam and three devices are. hard to manage. With the elimination of the casting robot, the coordination of the movements is simplified, inasmuch as three are reduced to two, saving time and money. The furnace next to the mold is also eliminated, recovering production space.
- the newly designed bench to which various functions have been attributed, particularly the suitability for holding low-pressure casting molds and molds for free- fall casting, as well as those for use with "combined” technology, is also used for housing a part consisting of components that are normally part of the frames of the same molds.
- the mold can be used for longer by simply repainting the figure parts.
- the slides carriers of the mold slides can rotate upwards by over 45°, allowing the operator to easily repaint the mold figure and to clean it.
