[0003] Publication (Announcement) No.: CN220295840U discloses a liftable pouring machine, including a base, a lifting shell, a heating furnace, a height adjustment mechanism, a dumping mechanism and a guide mechanism. A lifting shell is installed on the upper side of the base, and a height adjustment mechanism for driving the lifting shell to move up and down is installed on the base. The heating furnace is rotatably connected in the lifting shell, and two dumping mechanisms for driving the heating furnace to swing are installed in the lifting shell. The upper end of the heating furnace is installed with a guide mechanism, and the guide mechanism includes: a guide nozzle, a telescopic nozzle, a limit rod, a screw and a fastening nut.

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] Referring to the accompanying drawings: This type of pouring machine that can be raised and lowered includes a base 1, a lifting platform 2 that is arranged on the base 1 and can be raised and lowered, and a heating furnace 3 that is rotatably arranged on the lifting platform 2. A hydraulic cylinder 4 is arranged between the rear end outer peripheral surface of the heating furnace 3 and the lifting platform 2 to drive the heating furnace 3 to flip toward the front end during pouring, and a guide nozzle 5 is arranged on the front end outer peripheral surface. The hydraulic cylinder 4 is hinged to the heating furnace 3 and the lifting platform 2. Two connecting ears 6 that are symmetrically distributed on both sides are arranged on the rear end outer peripheral surface of the heating furnace 3. A detachable hinge seat 7 is arranged on the connecting ear 6. The hinge seat 7 is hinged to the piston rod of the hydraulic cylinder 4. A detachable extension block 8 is arranged at the bottom of the heating furnace 3. The extension block 8 is fixedly connected to a rotating shaft 9 that is rotatably arranged on the lifting platform 2. The principle of the utility model is that the hinge seat 7 and the connecting ear 6, the extension block 8 and the heating furnace 3 are all detachably connected. In this way, when disassembling the heating furnace 3, it is not necessary to be as cumbersome as in the prior art, and the heating furnace 3 can be quickly disassembled, thereby improving efficiency.

[0020] The connecting ear 6 has an assembly base surface 61 and an assembly back surface 62. The assembly base surface 61 is provided with a positioning node 10 that limits the final assembly position of the hinge seat 7 in the connecting ear 6. The assembly back surface 62 is provided with a locking arm 20 that prevents the hinge seat 7 and the connecting ear 6 from being separated after the two are assembled. The hinge seat 7 has an assembly mating surface 71 that contacts the assembly base surface 61. The assembly mating surface 71 is provided with a positioning unit 30 combined with the positioning node 10. The positioning unit 30 is provided with a locking socket 40 combined with the locking arm 20. The combination of the positioning unit 30 and the positioning node 10 can quickly The setting position of the articulated seat 7 on the connecting ear 6 is quickly determined, and the assembly base surface 61 and the assembly mating surface 71 are both flat, so that the two can fit tightly together when in contact without generating a fitting gap. At the same time, it has a locking structure composed of a locking socket 40 and a locking arm 20. The locking socket 40 is set in the positioning unit 30 and passes through the positioning node 10, so that the locking arm 20 can prevent the positioning unit 30 from moving in the opposite direction of the assembly direction when combined with the locking socket 40, thereby ensuring the stable combination of the connecting ear 6 and the articulated seat 7. This method also makes disassembly convenient.

[0021] The positioning node 10 includes an enclosing wall 101 formed on the assembly base surface 61, and a passing space 102 defined within the enclosing wall 101 and allowing the positioning unit 30 to pass through. The enclosing wall 101 abuts against the positioning unit 30 when the positioning unit 30 passes through the passing space 102. The positioning node 10 is configured to be a through hole penetrating the connecting ear 6. The hole wall of the through hole forms the enclosing wall 101. The space that allows the positioning unit 30 to pass through forms the passing space 102. The passing space 102 is combined with the wall thickness of the connecting ear 6 so that part of the positioning unit 30 can be placed inside, and the part placed inside can abut against the enclosing wall 101. The abutment generates resistance that limits the mobility of the positioning unit 30, so that the positioning unit 30 can be stably maintained in the positioning node 10 when it has not yet been locked by the locking arm 20, and it is also convenient for subsequent locking and cooperation with the locking arm 20.

[0022] The positioning unit 30 includes a main body 301 in a columnar shape. The main body 301 is combined with the positioning node 10 along the assembly guide direction, and part of the main body 301 is placed in the through space 102 and abuts against the enclosing wall 101. The locking socket 40 is set on the main body 301. The main body 301 uses the columnar shape to give itself a usable length, which can meet the needs of passing through the positioning node 10 and setting the locking socket 40.

[0023] One end of the locking arm 20 is rotatably set on the assembly back side 62, and the other end is inserted into the locking socket 40. Two extension rods 201 are symmetrically distributed on both sides on the lower end surface of the end of the locking arm 20 inserted into the locking socket 40. The spacing between the two extension rods 201 is adapted to the outer diameter of the main body 301, and when the main body 301 is placed inside, the two extension rods 201 are both in contact with the main body 301. The locking arm 20 is connected to or released from the locking socket 40 by rotation. The setting of the extension rod 201 enables the locking arm 20 and the main body 301 to be plugged into each other, which can further increase the stability of the locking combination.

[0024] The extension block 8 is provided with a screw 81 which is threadedly connected to the bottom of the heating furnace 3, that is, when the two are separated, the connection with the extension block 8 can be achieved by rotating the heating furnace 3, and the threaded connection method can provide a stable connection effect and will not affect the use of the heating furnace 3.
