Description

Technical field:

[0001] The utility model relates to the technical field of calcium stone pots, in particular to an automatic mold opening and closing device for calcium stone pots. Background technology:

[0002] The calcium carbide pot is mainly used in calcium carbide production. Its specific purpose is to transfer the molten calcium carbide produced in the calcium carbide furnace into the calcium carbide pot for cooling and solidification, and then use special calcium carbide clamps to grab and transport it.

[0003] The pot ears required for the existing calcium carbide pot are basically embedded in the V-shaped notches on both sides of the calcium carbide pot. By manually knocking the pins on the pot ears, the pot ears fall from the notches on the calcium carbide pot to the ground. Removing the pot ears is labor-intensive and has a high safety hazard of easily hitting the feet, which poses certain safety risks. Moreover, after the calcium carbide is clamped with pliers, the pot ears need to be manually closed.

[0026] See also Figure 1-9 The utility model provides a technical solution for an automatic mold opening and closing device for an electric stone pot:

The end of the toggle connecting rod 3 away from the pot ear 2 is rotatably provided with a roller 4. The upper end face of the limiting support plate 1.2 is movably abutted against the lower end face of the connecting plate 2.1, so that the movable angle range of the pot ear 2 is 0-60°, thereby ensuring that the roller 4 can move normally on the upper surface of the support platform 6.10.

[0028] A locking mechanism 5 for locking the pot ear 2 is provided on the top of the pot body 1 and near the outer surface of the wedge-shaped groove 1.1. Two opening and closing membrane mechanisms 6 for opening or closing the pot ears 2 are symmetrically provided on both sides of the pot body 1. An opening and closing lock mechanism 7 for opening or closing the locking mechanism 5 is also provided inside the opening and closing membrane mechanism 6.

[0029] The locking mechanism 5 includes: a screw 5.1, a limit block 5.2, a baffle 5.3 and two shifting posts 5.4; one end of the screw 5.1 is fixed to the top of the pot body 1 and close to the outer surface of the wedge-shaped groove 1.1, the limit block 5.2 is fixed to the top of the pot body 1 and close to the outer surface of the wedge-shaped groove 1.1 and is located below the screw 5.1, and a threaded hole 5.31 is provided in the middle of the baffle 5.3 with which the screw 5.1 is threadedly connected, and the two shifting posts 5.4 are respectively fixed to the same surface of the baffle 5.3 and are located on both sides of the threaded hole 5.31. After the baffle 5.3 is tightened by thread rotation, it clamps the pot ear 2 in the wedge-shaped groove 1.1 to prevent the pot ear 2 from falling off during the bumpy movement of the transfer vehicle 8; the surface of the baffle 5.3 close to the wedge-shaped groove 1.1 is movably abutted against the surface of the limit block 5.2.

[0030] The membrane opening and closing mechanism 6 comprises: two symmetrically vertically arranged support frames 6.1, an I-beam 6.2, a spring buffer 6.3, a second I-beam 6.4, a channel steel 6.5, a pulley 6.6, a slide rail 6.7, an opening plate 6.8, a closing plate 6.9 and a support platform 6.10;

[0031] A first I-beam 6.2 is connected between the tops of the two support frames 6.1. Three spring buffers 6.3 are fixed to the lower surface of the first I-beam 6.2. The lower ends of the spring buffers 6.3 are fixed to the upper surface of the second I-beam 6.4. Two channel steels 6.5 are symmetrically fixed to the two ends of the second I-beam 6.4.

The pulleys 6.6 slide on the slide rails 6.7. A cutout plate 6.8 is fixed to the side of the second I-beam 6.4 close to the pot body 1.

[0032] At the same time, a closing template 6.9 is provided below the opening template 6.8. The opening template 6.8 is formed into a "V" shape and has an obtuse angle by bending; the front of the closing template 6.9 is an "obtuse triangle" and its interior is hollow and vertically opened with a through hole 6.91. The closing template 6.9 is located on the upper surface of the support platform 6.10. The upper surface of the support platform 6.10 is opened with a strip through groove 6.101. The through hole 6.91 and the strip through groove 6.101 are used to pass bolts to thread and fix the closing template 6.9 to the support platform 6.10. At the same time, the relative distance between the closing template 6.9 and the opening template 6.8 can be adjusted so that the equipment can operate normally; the lower surface of the long part of the opening template 6.8 is parallel to and corresponds to the upper surface of the long part of the closing template 6.9, so that the moving track of the roller 4 is formed between the lower surface of the opening template 6.8 and the upper surface of the closing template 6.9. The roller 4 rotates the pot ear 2 during the movement of the moving track to realize the opening or closing of the pot ear 2.

[0033] The opening and closing locking mechanism 7 includes: a first stopper 7.1, a second stopper 7.2 and a spring piece 7.3; the first stopper 7.1 and the second stopper 7.2 are both fixed on the support frame 6.1 near the upper surface of the short part of the closing template 6.9, and the first stopper 7.1 and the second stopper 7.2 are both located above the support platform 6.10, and the second stopper 7.2 is located below the first stopper 7.1 and close to the closing template 6.9. A spring piece 7.3 is rotatably provided on the support frame 6.1 between the first stopper 7.1 and the second stopper 7.2, and the top end of the spring piece 7.3 movably abuts against the inner side surfaces opposite to the first stopper 7.1 and the second stopper 7.2, and the bottom lower surface of the spring piece 7.3 movably abuts against the upper surface of the stopper 5.3. When the stopper 5.3 passes the spring piece 7.3, the stopper 5.3 rotates to realize opening or closing of the locking mechanism 5.

[0034] To understand the operation of the device, please refer to Figure 6 、 Figure 8 and Figure 9 , the specific working principle is divided into automatic mold opening process and automatic mold closing process;

[0035] In the automatic mold opening process: before the mold is opened, the baffle 5.3 is always placed horizontally, and due to the presence of the limit block 5.2, the baffle 5.3 can only rotate clockwise. The transfer vehicle 8 moves the pot body 1 along the mold opening direction and first passes through the opening and closing locking mechanism 7 to open the locking mechanism 5;

[0036] That is, when the baffle 5.3 passes the spring plate 7.3, the spring plate 7.3 initially presses against the baffle 5.3. However, as the baffle 5.3 continues to move forward, the top of the spring plate 7.3 contacts the first stopper 7.1, causing the spring plate 7.3 to elastically deform and rest on the upper surface of the baffle 5.3. When the screw 5.1 passes through the bottom of the spring plate 7.3, the spring plate 7.3 gradually recovers its deformation capacity, and the bottom of the spring plate 7.3 forces the baffle 5.3 to rotate clockwise, causing the baffle 5.3 to be placed vertically, thereby opening the locking mechanism 5. The roller 4 then enters the movable track between the lower surface of the opening template 6.8 and the upper surface of the closing template 6.9. The roller 4 moves along the lower surface of the opening template 6.8 while driving the pot ears 2 to gradually open downward. The roller 4 finally lands on the upper surface of the support platform 6.10 and continues to move. At this point, the pot ears 2 are completely open, facilitating the subsequent clamping and transportation work.

[0037] During the automatic mold opening process, before the mold is closed, the baffle 5.3 is always placed vertically, and due to the presence of the limit block 5.2, the baffle 5.3 can only rotate counterclockwise. The transfer vehicle 8 first moves the pot body 1 along the mold closing direction on the upper surface of the support platform 6.10 through the roller 4, and then continues to move into the moving track between the lower surface of the opening template 6.8 and the upper surface of the closing template 6.9. The roller 4 moves along the upper surface of the closing template 6.9 and drives the pot ears 2 to gradually close upward until the roller 4 moves to the top of the closing template 6.9. At this time, the pot ears 2 are just completely closed; then the transfer vehicle moves to the opening and closing locking mechanism 7 to close the locking mechanism 5.

[0038] That is, when the baffle 5.3 passes the spring piece 7.3, the spring piece 7.3 first presses against the baffle 5.3, but as the baffle 5.3 continues to move forward, the spring piece 7.3 rotates counterclockwise, and the top end of the spring piece 7.3 abuts against the second stopper 7.2, so that the spring piece 7.3 simultaneously moves the baffle 5.3 counterclockwise, so that the baffle 5.3 is placed horizontally, clamping the pot ear 2 in the wedge-shaped groove 1.1, completing the locking action.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
