Definitions
- the present invention relates to a cam device for the extraction and folding of the front plate in a vertical molding machine, CT 1 ⁇ has been designed to avoid abrupt variations in kb movements that the plate itself must perform in the phases of displacement and tilting of the same, to ⁇ ermit the extraction of each speck of sand as well as the conima tion or previous molding of it.
- Sandblast molding machines in which the production and output of the specks is carried out in an upright position, have a generally ⁇ P tai.gular chamber in which the sand is blown, through a hopper or bell set in the part above, said chamber being closed at one of its ends by means of a movable and tilting plate to allow the molten speck to exit, while at the other end it is closed by a rear plate associated with a compaction piston, which also serves to effect the thrust and corresponding ejection of the speck, to couple it on the pile of specks produced previously.
- Obtaining the speck is achieved by sand sucking in the chamber, the sand being then pressed by opposing thrust of both plates.
- the opening and folding of the tilting plate is then carried out to allow the output of the speck, which is achieved by pushing the rear plate associated with the thrust piston, thereby causing the extraction of the speck and its positioning on the previously obtained stack. .
- various types of drive mechanisms are used for the folding and opening of the rtt ⁇ swingarm, among which one that is constituted from a cam that supports through its upper face on a follower can be used, so that said cam is related to the tilting plate so that in the movement of that one and after its support in the follower the tilting of the plate takes place.
- the device that has been recommended has been used to solve the problem described above, based on a simple solution but no less effective, having taken into account the efforts supported by the components of the device to avoid abrupt variations in its operation.
- the movements of the plate The movements of the plate.
- the device of the invention is constituted from a cam whose active face is located downwards, the support follower being located at the bottom, which will prevent the formation and deposition of dirt between both elements.
- the cam is articulated on one side to a longitudinally movable frame, which in turn is articulated the tilting front plate; while on the other hand the said cam is articulated to an ice, articulated in turn by the opposite end to the tilting plate itself.
- the movable frame to which the cam is associated is driven, with the interposition of bars, by a cylinder opposed to the thrust cylinder of the rear plate, producing the displacement, in one way or another, of the frame itself.
- the thrust of the cylinder causes only the longitudinal displacement of the front plate and its extraction, until the cam comes into contact with the follower, at which point, if the thrust of the cylinder is maintained, the cam will begin to swing by pushing to the crank and is in turn to the front plate, making it bascule to free the output of the speck.
- Figure 1 shows a side view of the cam device in multiple positions that the cam itself can occupy between the rest position and the final tilting position.
- Figures 2, 3 and 4.- They show two views, corresponding to as many phases of the movements of the cam device object of the invention.
- the device of the invention is constituted from a cam (1) whose active face (2) is located downwards, is articulated through one of its points (3) to a frame (4) longitudinally movable, while through another point (5) distant from the previous one the cam (1) is articulated to a connecting rod (6), which at its opposite end is in turn articulated according to the point
- the molding machine in which said device is applicable has the corresponding molding chamber in which the speck (11) will be formed, above which the hopper or bell (12) is arranged for you birds of which the sand is blown.
- the tilting ciato (7) closes the front part of the said chamber, while the rear part closes by means of a second plate (13) which is actuated in its displacement through a cylinder (14), there being another cylinder (15) that, through bars (16), drives the movable frame (4).
