[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-4As shown, this utility model provides a technical solution: an automatic opening and closing and positioning device for casting molds, including a base 1, a plurality of columns 4 fixedly connected to the top of the base 1, a top plate 5 fixedly connected to the top of the columns 4, a hydraulic rod 6 provided at the top of the top plate 5, and a lifting plate 7 fixedly connected to the output rod of the hydraulic rod 6 by a threaded bolt. The four corners of the lifting plate 7 are mounted on the outside of the columns 4 by means of a convenient device 2. The convenient device 2 includes a plurality of slots 21, each slot 21 being fixedly fixed at one of the four corners of the lifting plate 7. A slider 22 is slidably connected to the inner wall of the slot 21, and a spring 23 is provided at one end of the slider 22. The two ends of the spring 23 are fixedly connected to one side of the slider 22 and one side of the inner wall of the slot 21, respectively. The slider 22 is positioned away from the slot 21. A first locking block 24 is fixedly connected to the end of the device. A second locking block 25 is connected to one side of the first locking block 24 via an auxiliary device 3. When the casting mold is installed on the automatic opening and closing and positioning device by setting the slot block 21, the lifting plate 7 is raised so that the lifting plate 7 is level with the base 1. Then, the lifting plate 7 is inserted horizontally between the columns 4 above the base 1, so that the first locking block 24 at one end of the slider 22 inside the slot block 21 at the four corners of the lifting plate 7 contacts the surface of the column 4. When the first locking block 24 contacts the surface of the column 4, it pushes the slider 22 to move into the inside of the slot block 21 and compresses the spring 23. After the lifting plate 7 is moved so that the positions of the first locking blocks 24 at the four corners of the lifting plate 7 are aligned with the columns 4, the springs 23 inside each slot block 21 return to their original state. The slider 22 will be pushed outward to lock the first locking block 24 onto the outer surface of the column 4. Then, with the help of the auxiliary device 3, the second locking block 25 will be installed on one side of the first locking block 24, so that the four corners of the lifting plate 7 are fitted onto the outer surface of the column 4 by the first locking block 24 and the second locking block 25. Finally, the upper and lower molds of the casting mold are fixed to the surfaces of the lifting plate 7 and the base 1, respectively. The hydraulic rod 6 is controlled by the control box at the top of the top plate 5 to drive the lifting plate 7 and the upper mold of the casting mold to move up and down to open and close. At the same time, the first locking block 24 and the second locking block 25 at the four corners of the outer surface of the lifting plate 7 will slide on the outer surface of the column 4 to position the lifting plate 7 and the upper mold of the casting mold to the base 1. When it is necessary to remove the lifting plate 7, the lifting plate 7 is removed by... Remove the second locking block 25 fixed at the four corners of the surface by the auxiliary device 3, then disconnect the lifting plate 7 from the output rod of the hydraulic rod 6, and push the lifting plate 7 in one direction to move the first locking block 24 away from the outer surface of the column 4. By setting the convenient device 2, by installing the slot block 21 at the four corners of the lifting plate 7, the first locking block 24 on one side of the slot block 21 is locked on the outer surface of the column 4, and the second locking block 25 is combined with the first locking block 24 to install the four corners of the lifting plate 7 on the outside of the column 4. Remove the second locking block 25 and move the lifting plate 7 away from the base 1 to remove the lifting plate 7. It is not necessary to disassemble the entire device to disassemble and install the lifting plate 7, which greatly improves the convenience and practicality of using the automatic opening and closing and positioning device.

[0021] L-shaped blocks 27 are fixedly connected to both sides of the first locking block 24. One side of the L-shaped block 27 slides on one side of the slot block 21. When the slider 22 moves inside the slot block 21 and drives the first locking block 24 to move, one side of the L-shaped block 27 will slide on both sides of the slot block 21. The angle between the slot block 21 and the first locking block 24 can be further restricted by the L-shaped block 27, so as to avoid the angle between the first locking block 24 and the slot block 21 from deflecting as much as possible.

[0022] A round rod 26 is fixedly connected to one side of the inner wall of the groove block 21. The slider 22 slides on the outer surface of the round rod 26. When the slider 22 moves inside the groove block 21, it will slide on the outer surface of the round rod 26. The round rod 26 can further limit the angle between the slider 22 and the groove block 21, and avoid the slider 22 from falling or tilting at the end away from the groove block 21 as much as possible. The inner diameter of the spring 23 is larger than the diameter of the round rod 26. The spring 23 is located outside the round rod 26. When the slider 22 moves inside the groove block 21 and causes the spring 23 to deform, the spring 23 will move outside the round rod 26. The round rod 26 can reinforce the internal shape of the spring 23, and avoid the spring 23 from twisting when deformed, which would affect normal use.

[0023] The auxiliary device 3 includes insert blocks 34, which are fixed to both ends of the second locking block 25. Several bolts 33 are threaded onto the inner wall of the insert blocks 34. Slots 31 are provided at both ends of the first locking block 24, and through holes 32 are provided on both sides of the inner wall of the slots 31, penetrating the outer surface of the first locking block 24. When installing the lifting plate 7, after the first locking block 24 is locked onto the outer surface of the column 4, the insert blocks 34 at both ends of the second locking block 25 are inserted into the slots 31 at each of the first locking blocks 24. Then, bolts 33 are inserted through the through holes 32 on the outer surface of the first locking block 24 and into the inner wall of the insert block 34. The bolts 33 are rotated to engage with the second locking block 25. The inner walls of the inserts 34 at both ends are threaded together to fix the second locking block 25 to the outer surface of the first locking block 24. By rotating the bolt 33, the second locking block 25 can be removed from the inserts 34 and the first locking block 24. Then, the inserts 34 at both ends of the second locking block 25 can be pulled out from the slots 31 at both ends of the first locking block 24 to remove the second locking block 25. This further improves the flexibility of the convenient device 2 during use. Several elastic ropes 35 are fixedly connected to the outer surface of the second locking block 25. The end of the elastic rope 35 away from the second locking block 25 is fixedly connected to one end of the bolt 33. By setting the elastic rope 35, the bolt 33 can be fixed to the outside of the second locking block 25 to prevent the bolt 33 from falling off and being lost when disassembling and assembling the second locking block 25.

[0024] The working principle of this utility model is as follows: When the casting mold is installed on the automatic opening and closing and positioning device, the lifting plate 7 is raised so that it is level with the base 1. Then, the lifting plate 7 is inserted horizontally between the columns 4 above the base 1, so that the first locking block 24 at one end of the slider 22 inside the slot 21 at the four corners of the lifting plate 7 contacts the surface of the column 4. When the first locking block 24 contacts the surface of the column 4, it pushes the slider 22 to move into the slot 21 and compresses the spring 23, thus moving the lifting plate 7 to raise the height of the mold. After the first locking blocks 24 at the four corners of the lowering plate 7 are aligned with the position of the column 4, the springs 23 inside each slot block 21 return to their original state, pushing the slider 22 to move outward and locking the first locking blocks 24 onto the outer surface of the column 4. Then, insert the inserts 34 at both ends of the second locking blocks 25 into the slots 31 at both ends of the first locking blocks 24. Then, use bolts 33 to pass through the through holes 32 on the outer surface of the first locking blocks 24 and insert them into the inner wall of the inserts 34. Rotate the bolts 33 to make the bolts 33 engage with the second locking blocks 25. The inner walls of the insert blocks 34 at both ends of block 25 are threaded together to fix the second locking block 25 to the outer surface of the first locking block 24. This allows the four corners of the lifting plate 7 to be fitted onto the outer surface of the column 4 via the first locking block 24 and the second locking block 25. Finally, the upper and lower molds of the casting mold are fixed to the surfaces of the lifting plate 7 and the base 1, respectively. The hydraulic rod 6 is controlled by the control box at the top of the top plate 5 to move the lifting plate 7 and the upper mold of the casting mold up and down to open and close. At the same time, the first locking block 24 and the second locking block 25 at the four corners of the outer surface of the lifting plate 7 will slide on the outer surface of the column 4 to position the lifting plate 7 and the upper mold of the casting mold relative to the base 1. When the lifting plate 7 needs to be removed, rotate the bolt 33 to disengage it from the insert blocks 34 and the first locking block 24. Then, pull out the insert blocks 34 at both ends of the second locking block 25 from the slots 31 at both ends of the first locking block 24 to remove the second locking block 25. Then, disconnect the lifting plate 7 from the output rod of the hydraulic rod 6 and push the lifting plate 7 in one direction to move the first locking block 24 away from the outer surface of the column 4.
