DESCRIPTION OF THE PREFERRED EMBODIMENTS A mold disassembling device according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a system diagram of a mold removal system a to which the apparatus of this embodiment is applied. This system a has a mold disassembly process, a shotplast process C, and a weir folding finishing process d in the middle of one main endless chain conveyor (hereinafter referred to as the main conveyor mechanism) 1, and one rotation of the main conveyor mechanism 1 It is configured so that a cast product can be obtained. Figures 2 and 3 show the main conveyor mechanism 1, with Figure 2 being a partially cutaway front view and Figure 3 being a partially cutaway front view.
The figure is a sectional view taken along the line ■--■ in FIG. 2. The main conveyor mechanism 1 has two upper and lower rails 2a and 2b, and the upper rail 2a is equipped with a chain 3 that always moves in a fixed direction (direction of arrow X in Fig. 2), and the lower rail 2a A plurality of hooks 4 are movably hung vertically on the rail 2b. These hooks 4, 4... are upwardly directed protrusions that are rotatably supported on the shaft of a roller 4a that suspends downward protrusions 3a provided on the chain 3 at required intervals. 4b, it acts to move along with the movement of the chain 3. When one hook 4 approaches a stopped hook 4 in front of the hook 4 in the forward direction, the cam 4c integrally formed with the above-mentioned protrusion 41 comes into contact with the shaft of the roller 4a of the hook 4 in front of the hook 4. cam 4c is lifted up, and that cam 4c is lifted up.
The protrusion 4b integrated with the chain C is rotated downward, whereby the protrusion 4b is released from contact with the protrusion 3a of the chain 3, and the movement of the hook 4 is stopped. Then, when the front hook 4 starts moving, the following hook 4
The protrusion 4b protrudes upward and returns to its original position, and the chain 3
The movement will be resumed. Note that this cam 4c is held at a predetermined position. In the figure, reference numeral 5 denotes a hanger whose upper end is suspended from a hook 4, and from the lower end of which a sprue portion A' for a cast product can be suspended and held, as will be described later. Figures 4 and 5 show the mold disassembly process part of the main conveyor@structure 1, and the lower rail is composed of lifting rails 2b' divided into predetermined lengths. The elevating rail 2b' is configured to move downward a predetermined distance by vertical movement driving means 6a, 6b consisting of a pair of hydraulic cylinders or air cylinders. That is, as shown in FIG. 5, the elevating rail 2b' is fixed to the lower end of a connecting rod 8 that hangs down from both ends of the upper arm 7 of the vertical movement drive means 6a, 6b. Therefore, when the vertical movement drive means 6a, 6b moves upward, the vertical movement rails 2b' are located at the positions indicated by the two-dot chain lines, and the lower rails 2b on both the left and right sides are positioned as shown in FIG.
Therefore, the hook 4 in this lifting rail 2b' can be moved by the movement of the chain 3 as described above. On the other hand, when the vertical movement drive means 6a, 6b moves downward and its elevating rail 2b' descends from the solid line position, the protrusion 3a of the chain 3 can no longer come into contact with the protrusion 4b of the hook 4, and the hook 4 is not moved by the chain 3 and thus its hook 4 can be stopped in that position. In Fig. 4, reference numeral 9 denotes a stopper, which stops the subsequent hook 4 moving on the lower rail 2b and allows it to fall when the lifting rail (2b'), which is a part of the lower rail 2b, descends. It acts to prevent Further, when the elevating rail 2b' rises by 1" and reaches the same horizontal plane as the left and right lower rails 2b, it moves backward by a cam action, thereby acting to release the subsequent hook 4 from stopping. 6 to 9 show a casting holding mechanism (hereinafter referred to as holding mechanism) bl provided in the mold disassembly process. The holding mechanism b1 is provided at the rear end side of the belt conveyor 10, which corresponds to a mold conveying means for conveying the poured mold B, and is composed of a mold pushing part 11, a damper 12, and a hanger holding part 13. has been done. As shown in FIG.
, 14b, the belt conveyor 10 is moved by the cylinder 15.
A truck 16 that is moved back and forth in the conveyance direction, a pressing plate 18 installed at the top of the truck so that it can be moved up and down by a pair of cylinders 17a and 17b, and side plates 19a and 19b extending forward from both sides of the pressing plate. It is made up of. 0 The damper 12 is provided with one end rotatably supported at a position on the extension of the upper surface of the bell 1 to the conveyor 10, and is moved from the same plane as the upper surface of the bell 1 to the conveyor 10 in FIG. 6 by the cylinder 20. It is configured to rotate downward as shown by the dotted chain line. The hanger holding part 13 is for fixing the hanger 5 suspended on the hook 4, and as shown in FIG.
, 21b are crossed, and an elongated hole 22 is provided at the intersection, and a pin 24 provided at the tip of the screw 1 of the cylinder 23 is loosely fitted into this elongated hole. Therefore, when the cylinder 23 extends forward, the presser piece 2
The other ends (tips) of 1a and 21b open, and when the cylinder 23 retreats, the tips close, allowing the hanger 5 to be clamped and fixed. In FIG. 6, 25 is a cylinder, which includes a presser foot 1, a piece 21. a, 21. b and the cylinder 2 that opens and closes it.
3 can be moved back and forth. Next, the operation of the holding mechanism b1 having the above configuration will be explained with reference to FIG. 9 as well. Assume that the poured mold B is now being conveyed on the belt conveyor 10 toward its tip. At this time, the mold pushing part 11 is in a state where the piston rods of the cylinders 17a and 17b are raised to the position shown in FIG. 6A. Therefore, the press plate 18 does not interfere with the transfer of the mold B by the belt conveyor 10. On the other hand, the lifting rail 2b' is located at a predetermined position with the piston rod of the cylinder 6a6b being lowered (see the solid line position in FIG. 5). Among the hangers 5 held on the lowered lifting rail 2b', the hanger 5 at a position facing the bell 1 to the conveyor 10 is fixed by a hanger holding part 13. That is, when the piston rod [2] of the cylinder 25 is extended and the tips of the presser pieces 2], a, and 21b are located on the hanger 5, the piston rod of the cylinder 23 is retreated and the presser pieces 21. The tips of a21 and b are closed, and the hanger 5 is clamped and fixed. Next, the suppression plate 18 presses the cylinder 17a of the mold pushing part 11.
The lowering of the piston rod of the cylinder 15 positions it at the mouth region indicated by the solid line in FIG. 6, after which the piston rod of the cylinder 15 is extended. As a result, mold B is attached to hanger 5.
(see position C in Figure 6), sprue part A'
or held by the hanger 5 (see Fig. 9). Therefore, the lowering position of the lifting rail 2b' is adjusted in advance so that the hanger 5 comes into contact with the sprue portion A'. When the cast product A is held on the hanger 5, the screws 1 to 1 of the cylinder 20 are retracted and the damper 12 is opened. As a result, most of the mold sand falls into the hopper 26. Thereafter, the hanger presser 13 operates in the opposite manner as described above to release the fixation of the hanger 5, and the damper 12 returns to its original position, that is, to the same position as the upper surface of the bell 1 to the conveyor 10, and then the mold presser 11 The mold B is also moved back to its original position and raised to return to the position shown in FIG. The cast product A held on the hanger 5 is conveyed to the vibration mechanism b2 shown in FIGS. 10 and 11, which is located adjacent to the holding mechanism b1 in the latter half of the mold disassembly process. This conveyance is performed by the lower rail 2b as described with reference to FIG.
This is done by raising the elevator rail 2b'. When the hanger 5 holding the cast product A reaches a predetermined position on its elevating rail 2b', the elevating rail 2b' is lowered again and stopped at that position. Furthermore, when the bunker 5 holding this cast product A or the vibrator 'f14 b2 is moved to the position of A new casting A is held. The vibration mechanism b2 has an arm-shaped vibration part 33 attached to a vibration plate 32 that is vibrated by a vibration motor 31,
The hanger 5 is supported by the vibrating part 33, and the hanger 5 and the cast product A held therein are vibrated together. The diaphragm 32 is mounted via a sponk 36 on a pedestal 35 which is lifted up by a cylinder 34 corresponding to a moving means, and the pedestal 35 is mounted on a cart 38 which is similarly moved back and forth by a cylinder 37 which also corresponds to a moving means. Fixed. In order to vibrate the casting A and cause the sand adhering to it to fall (=I), first operate the cylinder 37 to move the cart 38 forward, and then move the tip of the vibrator 33 into the hanger 5. Next, the cylinder 34 is operated to move the pedestal 35 upward to a predetermined height, and the bunker 5 - 5 is separated from the hook 4. Then, the vibration motor 31
is driven for a predetermined period of time (approximately 10 seconds). As a result, the cast product A is violently vibrated, and the adhering sand can be effectively separated. After the excitation is finished, the pedestal 35 is lowered and the bunker 5 is suspended from the hook 4 again. Next, the truck 38 moves backward, and the arm 33 moves so as not to become an obstacle to the subsequent transfer of the hanger 5. The hanger 5 holding the vibration-treated casting A is placed in the fourth
As explained with reference to the drawings, the elevating rail 2b' of the lower rail 2b is raised to transport the product to the next shop 1 for the blasting process C. The shot blasting step C is carried out by injecting a plus 1 material onto the casting A, similar to the well-known shot I blast. The blasting material can be sprayed in the main conveyor mechanism 16 with a force of 3, but since the blowing of the material from +1 to 16 causes the wear of the main conveyor mechanism 1 to progress rapidly, this embodiment uses an auxiliary force. Endless chain conveyor 111
Casting product A is transferred to tlI (hereinafter referred to as auxiliary conveyor +1! horizontal) 1', and the process is carried out here. Replacement of parts due to this sagging and wear is done only in the auxiliary conveyor mechanism 1', and running costs 1- can be reduced. The auxiliary conveyor mechanism 1' is constructed similarly to the F-article conveyor machine side 1, and the movement of the hanger 5 from the main conveyor mechanism 1 to this auxiliary conveyor mechanism 1' or vice versa is as shown in FIGS. 12 and 13. This is carried out by a transfer mechanism c1 corresponding to the moving means shown in FIG. Transport machine! Rcs is a pair of gripping parts 41. on which protrusions 5a and 5b provided at both left and right ends of the hanger 5 are placed. a
, 4.1a, and a rack 45 that is provided integrally with the grip portion 41a and is supported by meshing with a pinion 43 and an auxiliary pinion 44, which are rotated by a reversible motor 42,
The pinion 43 and the auxiliary pinion 44 are pivotally supported, and the rack 4
a support plate 47 having a roller 46 for guiding the movement of the support plate 5;
It is composed of a cylinder 48 that moves this support plate up and down. Therefore, the screws 1 to 1 of the cylinder 48 move up and down, and the reversible motor 42 is driven, so that the gripping portion 41a moves in the direction of the arrow Y in FIG. Hanker 5 can be transferred to fi1'. In addition, the shot blasting process product A is transferred again from the auxiliary conveyor mechanism 1' to the main conveyor mechanism 1.
12, the reversible motor 42 and cylinder 48 are driven in the direction opposite to the arrow Y in FIG. The cast product A processed in the shot blasting process C is conveyed by the main conveyor mechanism 1 to the weir finishing process d. The cast product A is cooled by air cooling during this transportation step 8 and during transportation from the above-mentioned mold disassembly step to shot plus step 1 to step C. Therefore, in order to ensure sufficient air cooling treatment, the transport distance from the shot blasting process C to the weir finishing process d is designed to be sufficiently long. In the weir folding finishing process d, the casting product A is removed from the hanger 5, and the sprue A' is separated using a folding tool, and when the casting product includes multiple products, each product is The hanger 5 from which the cast product A is not removed in the disassembled six-way folding finishing process d is sent back to the mold disassembly process by the main conveyor mechanism 1 and is used for holding the cast product. In the above actual example device, the holding structure b1 provided in the mold disassembly process is provided with a mold pushing part 11 on the rear end side of the belt conveyor 10 to which the poured mold B is conveyed,
Since the mold pushing part 11 is configured to press the mold B against the hanger 5 fixed by the hanger holding part 13, the sprue part of the manufactured product A can be held on the hanger 5 very easily. I'll come. The vibration mechanism b2 also includes an arm 33 that is vibrated by a vibration motor 31, and a hanger 5 that holds the cast product A.
Since it is configured to support the cast product A, it is possible to effectively vibrate the cast product A, and the sand removal rate can be increased. Furthermore, the shot blasting process C includes the main conveyor mechanism 1
Since the shot blasting process is carried out using the auxiliary conveyor mechanism 1' which is provided separately from the main conveyor mechanism 1, it is possible to carry out the shot blasting process without preventing the main conveyor mechanism 1 from being worn out by the shots 1 to blast. In addition, in the above-mentioned embodiment, the number of cast products A held on the hanger 5 by the holding mechanism b1 was one, but the hanger 5
Two hooks 4 may be provided in parallel, that is, two hooks 4 may be provided in parallel so that two cast products can be held at the same time. In this case, since the vibration mechanism b2 can also process two zeros at the same time, the processing efficiency can be further improved. Of course, there may be three or more.Also, in the mold disassembly process, a part of the lower rail 2b of the main conveyor mechanism 1 can be used as a lifting rail 2b' to move downward, and the movement of the hook 4 in this part is stopped. Alternatively, this lifting rail 2b' may be constructed in the same manner as the other lower rails 2b, and the chain 3 may be moved intermittently to temporarily stop the movement of the hook 4 during the lowering of the lifting rail. good. Effects of the Invention The device of the present invention has a main conveyor mechanism that suspends and moves the hanger, a mold conveyance means that conveys the poured mold to the R structure side of the main conveyor, and A damper that can be opened and closed, a hanger holder located on the damper that fixes the hanger, and a mold that is pressed against the fixed hanger so that the sprue part of the cast product is held by the hanger. It consists of a mold pushing part that vibrates and a vibration mechanism that vibrates the cast product held on the hanger, so the hanger can hold the sprue part of the cast product, and in this state it can be vibrated to remove sand. . Therefore, sand can be removed efficiently during the process of transferring the cast product, and the cast product will not be damaged during vibration. Furthermore, since the vibration mechanism is configured to vibrate the hanger by supporting it with an arm, the vibration can be efficiently transmitted to the cast product. Furthermore, since the shot blasting process is performed by an auxiliary conveyor mechanism provided separately from the main conveyor mechanism, wear of the main conveyor mechanism due to shot blasting can be prevented.
