Description

Technical Field

[0001] The invention relates to the technical field of static pressure molding line devices, in particular to a static pressure molding production line with a casing cooling function. Background Art

[0002] Static pressure molding line mainly refers to the abbreviation of the equipment production line for fully automatic molding in clay sand casting. It is a fully automatic molding with a box, high efficiency and good sand mold quality. It is mainly composed of molding station, core setting and box closing station, pouring and cooling station, sand falling station, etc., including static pressure molding main machine, molding auxiliary machine, casting mold conveyor, electric control hydraulic system and sand box, template frame and other process equipment.

[0003] After the assembling and pouring, it is necessary to wait for the casting in the sand box to cool down before the sand can be removed. In order to achieve self-cooling of the sand box during the production process, the static pressure molding line will be equipped with a cooling circulation line. The longer the distance the sand box travels on the cooling circulation line, the greater the extent of its own cooling. Due to the limitation of the floor space of the device, the distance of the cooling circulation line is generally short. If the cooling time of the casting is required to be longer, it is necessary to walk several more circles on the cooling circulation line, which will affect the subsequent production of castings in the entire production line and the cooling and transportation of the sand box, reducing the production efficiency of the casting.

[0017] A molding sand inlet 17 is provided on the first set of box supporting plates 16 on the upper part of the sand box return line 2, a first casting drop port 18 is provided on the first set of box supporting plates 16 on the upper part of the casting conveying mechanism 6, a first box-pushing machine 19 which can push the molding sand upward is installed at the bottom of the molding sand inlet 17, a sand box grabbing and transferring device 20 is installed on the first fixed frame 15 between the first box-pushing machine 19 and the sand box return line 2, the sand box grabbing and transferring device 20 can transfer the sand box 10 on the sand box return line 2 to the first box-pushing machine 19, and the first box-pushing machine 19 can push the molding sand in the sand box 10 into the set of box 12.

[0018] The working process of the first box-pushing machine 19 pushing the molding sand in the sand box 10 into the casing box 12 in the above process is as follows: the casing box grabbing and transferring device 41 of the first-stage box-pushing machine assembly 13 transfers an empty casing box 12 from the first casing box cooling line 4 to the molding sand inlet 17, and then the first box-pushing machine 19 pushes the molding sand in the sand box 10 into the casing box 12, and then the casing box grabbing and transferring device 41 transfers the casing box 12 to the first casing box cooling line 4 to participate in the casing box cooling line circulation.

[0019] A first cleaning mechanism 21 that can be pushed downward is installed on the first fixed frame 15 on the upper side of the first casting drop port 18. The first cleaning mechanism 21 can clean the floating sand on the inner wall of the casing 12 and push the castings in the casing 12 to the casting conveying mechanism 6. A casing grabbing and transferring device 41 is also installed on the first fixed frame 15. The casing grabbing and transferring device 41 can transfer the casing 12 on the first casing cooling line 4 to the bottom of the first cleaning mechanism 21, and can also transfer the casing 12 loaded with castings on the first casing supporting plate 16 to the first casing cooling line 4.

[0020] like Figure 5 As shown, the secondary box-poking machine assembly 14 includes a second fixed frame 22, which spans the first box-set cooling line 4 and the casting conveying mechanism 6, and a horizontally arranged second box-set supporting plate 23 is installed in the second fixed frame 22.

[0021] A second casting drop opening 42 is provided on the second casing support plate 23 on the upper side of the casting conveying mechanism 6, and a second cleaning mechanism 24 that can be pushed downward is installed on the second fixed frame 22 on the upper side of the second casting drop opening 42. The second cleaning mechanism 24 can clean the floating sand on the inner wall of the casing 12 and push the castings in the casing 12 onto the casting conveying mechanism 6. A casing grabbing and transferring device 41 is also installed on the second fixed frame 22, and the casing grabbing and transferring device 41 can transfer the casing 12 on the first casing cooling line 4 to the bottom of the second cleaning mechanism 24.

[0022] The casing grabbing and transferring device 41 and the sand box grabbing and transferring device 20 can be existing grabbing manipulators or clamping cylinder mechanisms, which can drive the sand box 10 or casing 12 to move together when grabbing and fixing them, so as to realize the transfer of the sand box 10 and casing 12. The first box-poking machine 19 can be a box-poking machine described in a Chinese patent publication with patent number "CN201105318Y", which can realize the upward lifting or downward pushing of the molding sand and castings in the casing 12 by vertically lifting the cylinder.

[0023] The first cleaning mechanism 21 and the second cleaning mechanism 24 can be vertical action components with cleaning devices, which can clean the inner wall of the casing. When the casing moves to the casting drop opening, the casting inside can be sanded out and taken out under the action of gravity, wherein the first cleaning mechanism 21 and the second cleaning mechanism 24 can not only clean the floating sand on the inner wall of the casing, but also have the function of poking the casing out of the casting, ensuring that the casting can be sanded out and taken out at the casting drop opening.

[0024] When the static pressure molding production line with the casing cooling function described in the present invention is used to produce castings, first, the static pressure molding casting production line 1 completes molding in the empty sand box, and then completes the pouring of molten iron, and through transportation, the sand box 10 with the casting is transferred to the sand box cooling line 3 via the sand box cooling transfer vehicle 7 for cooling and cooling, and then transferred to the first-level box-poking machine assembly 13 by the sand box cooling transfer vehicle 7. If the temperature drops to the specified temperature at this time, the sand box grabbing and transferring device 20 transfers the sand box 10 with the casting to the first box-poking machine 19, and the first box-poking machine 19 pushes the molding sand and casting inside the sand box 10 upward into the casing 12, and driven by the casing grabbing and transferring device 41, the casing 12 is transferred to the bottom of the first cleaning mechanism 21, and the first cleaning mechanism 21 is activated to push the casting in the casing downward onto the casting conveying mechanism 6, completing the sand removal operation.

[0025] If the temperature does not reach the specified temperature when it is transferred to the first box-poking machine assembly 13, the sand box grabbing and transferring device 20 transfers the sand box 10 with the casting to the first box-poking machine 19, and the first box-poking machine 19 pushes the molding sand and casting inside the sand box 10 upward into the sleeve box 12, and the sleeve box grabbing and transferring device 41 transfers the sleeve box 12 containing the casting to the first sleeve box cooling line 4, and after being transferred by the sleeve box cooling transfer vehicle 8, the sleeve box 12 containing the casting moves to the second sleeve box. The castings are cooled on the box cooling line 5 and then transferred to the secondary box-poking machine assembly 14 by the box-coating cooling transfer vehicle 8. The box-coating grabbing and transferring device 41 on the secondary box-poking machine assembly 14 grabs the box and transfers it to the bottom of the second cleaning mechanism 24. The second cleaning mechanism 24 is started to push the castings in the box downward onto the casting conveying mechanism 6 to complete the sand dropping and part picking operation. The above operation has a longer cooling walking distance and is suitable for casting products with a longer cooling time.

[0026] Furthermore, in order to facilitate the separation of the casing 12 and the casing traveling trolley 11 when the casing grabbing and transferring device 41 is in operation, Figure 6 , Figure 7 and Figure 8 As shown, the casing grabbing and transferring device 41 includes a moving frame 25, which can move on the upper side of the casing support plate, wherein the moving frame 25 can be a moving plate or a gantry with moving wheels, and can move on a fixed frame.

[0027] In order to achieve the clamping and fixing of the sleeve box 12, sleeve box clamping mechanisms are installed on both sides of the length direction of the bottom of the movable frame 25, and the sleeve box clamping mechanism includes a connecting frame 26, and two rows of horizontally arranged clamping wheels 27 are provided on the inner side of the connecting frame 26. A clamping plate 28 that cooperates with the clamping wheel 27 is provided on the side of the sleeve box 12. The clamping plate 28 is horizontally arranged, and guide slopes 40 are provided at both ends of the clamping plate 28 in the length direction. A horizontally arranged clamping cylinder 29 is also installed on the connecting frame 26, and a clamping hole 30 that cooperates with the clamping cylinder 29 is opened on the side of the sleeve box 12.

[0028] When the sleeve box 12 is located on the sleeve box walking trolley 11 and is transferred on the first sleeve box cooling line 4, the piston rod of the clamping cylinder 29 on the sleeve box clamping mechanism located in the fixed frame is retracted. When the sleeve box 12 gradually enters the sleeve box clamping mechanism, the guide ramp 40 first contacts the two rows of clamping wheels 27. While the sleeve box walking trolley 11 drives the sleeve box 12 to move, the sleeve box 12 gradually moves up. When the clamping plate 28 enters between the two rows of clamping wheels 27, the sleeve box 12 moves up to separate from the box walking trolley 11, and the box walking trolley 11 continues to move on the first sleeve box cooling line 4, and the sleeve box 12 is clamped by the sleeve box clamping mechanism. Subsequently, the piston rod of the clamping cylinder 29 extends out and enters the clamping hole 30, and the sleeve box 12 is locked by the clamping mechanism. The sleeve box grasping and transferring device 41 can drive the sleeve box 12 for subsequent transfer operations.

[0029] Furthermore, in order to realize the stable pushing out of the casting inside the box by the box-poking machine, Fig. 9 As shown, the first box-poking machine 19 includes a first mounting seat 31 disposed on the first fixing frame 15, a box-poking oil cylinder 32 is disposed on the first mounting seat 31, a box-poking plate 33 is mounted on the upper end of the piston rod of the box-poking oil cylinder 32, a first guide rod 34 is disposed on the box-poking plate 33, and a first guide sleeve 35 matched with the first guide rod 34 is disposed on the first mounting seat 31. When the piston rod of the box-poking oil cylinder 32 is pushed upward, the box-poking plate 33 can be driven to move upward to push the casting in the sand box upward into the sleeve box.

[0030] Furthermore, in order to realize that the cleaning mechanism can clean the floating sand inside the casing 12, it can also assist in realizing the sand removal, such as Fig.10 As shown, the first cleaning mechanism 21 and the second cleaning mechanism 24 both include a second mounting seat 43 arranged on a fixed frame, a cleaning cylinder 44 is provided on the second mounting seat 43, a cleaning plate 45 is installed at the lower end of the piston rod of the cleaning cylinder 44, a second guide rod 46 is provided on the cleaning plate 45, and a second guide sleeve 47 matching with the second guide rod 46 is provided on the second mounting seat 43.

[0031] The cleaning plate 45 cooperates with the opening and gradually falling position of the casing 12, the piston rod of the cleaning cylinder 44 is arranged downward, and the cleaning plate 45 is pushed downward to clean the floating sand on the inner wall of the casing 12, and at the same time, it can also assist in the sand removal of the casting.

[0032] Furthermore, in order to allow the sand box 10 containing the casting to reciprocate and circulate on the sand box cooling line 3 to meet the cooling requirements, Fig.11 As shown, the sand box cooling line 3 is provided with several rows arranged side by side, and each row of the sand box cooling line 3 is provided with a conveyor line, which can drive the sand boxes 10 to move in sequence, so that the sand boxes 10 are moved from the sand box cooling transfer vehicle 7 at one end of the sand box cooling line 3 to the sand box cooling transfer vehicle 7 at the other end. The sand box cooling transfer vehicles 7 at both ends of the length direction of the sand box cooling line 3 include a first light rail 36, a sand box transfer vehicle body 37 and a sand box pushing buffer cylinder 48. The piston rod of the sand box pushing buffer cylinder 48 can extend the sand on the first light rail 36 The sand box 10 can be pushed into the sand box cooling line 3, and the sand box 10 on the sand box cooling line 3 can also be pushed into the sand box transfer vehicle 37 on the first light rail 36 at the other end. The sand box transfer vehicle 37 can transfer and exchange the sand boxes 10 on each row of the sand box cooling line 3, and can also transfer the sand box 10 between the sand box cooling line 3 and the sand box return line 2. When the castings thereon meet the cooling requirements, the sand box cooling transfer vehicle 7 will transfer the sand box 10 containing the castings to the sand box return line 2 to facilitate subsequent transfer and sand removal operations.

[0033] The above operation process is described as follows: the sand box return line 2 and the sand box cooling line 3 perform transfer circulation on the sand box through the sand box cooling transfer vehicle 7 set at both ends in the length direction. The sand box cooling transfer vehicle 7 transfers the sand box 10 after pouring molten iron to the sand box return line 2 and each row of cooling lines of the sand box cooling line 3 respectively in turn. The cooled sand boxes 10 enter the sand box cooling transfer vehicle 7 on the other side of the cooling line respectively in turn. The sand box cooling transfer vehicle 7 transfers the cooled sand box 10 to the sand box return line 2 to prepare for entering the first-level box-poking machine assembly 13.

[0034] The sand box cooling transfer vehicles 7 at both ends of the sand box cooling line in the length direction have similar structures and are both provided with a first light rail 36, a sand box transfer vehicle body 37 and a sand box pushing buffer cylinder 48.
