Definitions
- the present invention relates to a molding chamber of green sand motes, which has been perfected in order to reduce the consumption of sand that participates in the speck, when allowed by the dimensions of the mold to be obtained, by means of under-dimensioning of the corresponding speck, based on obtaining a variable volumetric molding chamber.
- a tubular chamber is established, generally of rectangular section, which is closed by one of its ends by means of a movable, tilting wall to allow the output of the speck once molded while at its other end it closes with the wall associated with the compression piston itself and subsequent ejection of the speck, that is to say in said chamber four fixed walls, the constitutive ones of the tubular body, the upper one with the corresponding mouth or inlet hole for the sand, and two mobiles, in correspondence with the six general faces of the speck to obtain.
- the characteristics of the molding chamber itself define invariable parameters for it, since both its upper and lower walls and its side walls are fixed, so that when the casting is to be obtained, by being smaller, it would theoretically allow smaller motes to be used, that is, with less sand, this is not possible since the entire chamber defined in the machine must be filled with sand.
- the amount of sand available is not sufficient to respond to the machine's production rate. That is, the machine is capable of producing more specks than the sand available in the foundry can provide.
- these improvements consist in making said molding chamber of variable volumetry, allowing it to adapt it to the specific requirements of each type of speck to be obtained, specifically allowing to reduce the maximum and theoretical dimensions of said chamber.
- the walls of the camera are now mobile, specifically constituted on the basis of respective plates, which in turn are mounted on two plate holder racks, assisted by hydraulic cylinders for their mobilization, as well as guides conveniently established on a support, which ensure a perfect movement of the plates in their movements of approach and distancing.
- a model plate is defined, of adequate width to the speck to be obtained, variable width between a maximum level and a corresponding minimum level.
- Figure 1 shows, according to a diagram in which six sequences participate, the complete cycle of a molding chamber of conventional green sandbones, as described in the background section of the invention.
- FIG. 1 Shows a cross section of the blow chamber, made in accordance with the improvements of the invention.
- Figure 3. Shows a detail in plan of the same chamber of the previous figure, in a suitable position for obtaining maximum size specks.
- Figure 4. It shows a representation similar to that of the previous figure, but corresponding to the position of the camera to obtain minimum size specks.
- Figure 5. It shows, finally, a capricious and perspective representation of an alignment of specks, all of them for obtaining identical castings, half of them obtained with a conventional machine, and the other half with a machine provided of a molding chamber made in accordance with the improvements of the invention.
- each of these side walls is structured on the basis of a plate (11), which constitutes the wall itself, mounted on a plate-holder frame (12) to which guides (13) are integral, allowing their transverse displacement over a fixed support (14) when driven by a hydraulic cylinder (15), so that said plates (11) can adopt the position of maximum separation represented in a continuous line in Figure 2 or any intermediate distance to a maximum limit situation approximation, the one represented in dashed lines in the same figure. E these two limit positions are those that in turn have been represented in plan in figures 3 and 4.
- the plate holder frame (16) slides to which it is fixed by screws.
- the plate (17) provided with the corresponding model (18-18 ') and this assembly is fixed in turn, preferably by means of hydraulic triggers (19) to a plate (20) integral with the cylinder rod hydraulic (7), so that depending on the type of model (18 - 18 ') to be used in each case and on the same plate (20), different frames (16) will be mounted with their corresponding model plate (17 - 17 '- 18 - 18'), as shown for example in Figures 3 and 4.
- the improvements of the invention not only allow a drastic reduction in the consumption of sand to obtain the specks, but also offer the possibility of using tools of different models of smaller machines, a flexibility in the design of new tools, by having different options for surface distribution of the models, and an optimization of the process performance in case of limited sand capacity.
