[0002] Silicon carbide is a common industrial ceramic material and microelectronic material. It has high mechanical strength and chemical stability. Silicon carbide is also called diamond sand or refractory sand. Silicon carbide has great hardness, excellent thermal and electrical conductivity, and is resistant to oxidation at high temperatures. Silicon carbide reduction tanks are required in the reduction reaction of sponge iron.

[0003] The existing public patent CN201645638U discloses a silicon carbide reduction tank demoulding and flipping device, which is achieved by moving the silicon carbide reduction tank placed on a base and rammed into shape onto a flipping frame, further fixing it with a fixing buckle, pulling out the positioning pin, and then rotating the flipping frame, fixing the flipping frame with a positioning pin, and placing the other end of the silicon carbide reduction tank downward on a pallet, opening the fixing buckle, and moving the silicon carbide reduction tank to a specified place through the pallet, at which time the base of the silicon carbide reduction tank can be taken out, and this reciprocating action ensures the high yield of the silicon carbide reduction tank after molding, and reduces the breakage rate of the silicon carbide reduction tank.

[0004] After the above-mentioned device flips the silicon carbide reduction tank through the flip frame, the personnel needs to hold the positioning plate with one hand and insert the pin into the corresponding hole on the positioning plate with the other hand. Since the placement direction of the silicon carbide reduction tank is opposite to the installation direction of the pin, the personnel needs to move to the side of the pin after placing the silicon carbide reduction tank, installing the buckle, and rotating the positioning plate, so as to be able to visually observe whether the pin can be inserted into the corresponding hole on the positioning plate. This makes the above-mentioned device not consistent during use, which will affect the mold flipping efficiency of the silicon carbide reduction tank and has defects in use. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] See also Figure 1 , Figure 3The figure shows a chemical material mold turning device, including a base plate 1, a column 2 is fixedly installed on the upper end of the base plate 1, a turning frame 3 is installed on the outer side of the column 2, a rotating shaft 4 is fixedly installed on the side of the turning frame 3 close to the column 2, and the turning frame 3 is rotatably connected with the column 2 through the rotating shaft 4, and also includes a positioning pin 5 fixedly installed on the outer side of the turning frame 3, and the positioning pin 5 is located on the lower side of the rotating shaft 4, two symmetrically distributed limit rotation grooves 6 are provided on the column 2, and the positioning pin 5 is rotationally contacted with the column 2 through the limit rotation groove 6; a blocking structure 7 is used to position the positioning pin 5, and the two blocking structures 7 are respectively installed on the inner sides of the two limit rotation grooves 6; a deceleration component 8 is used to slow down the rotation speed of the turning frame 3, and a plurality of circumferentially equidistantly distributed deceleration components 8 are installed inside the column 2 and distributed on the outer side of the rotating shaft 4.

[0024] See also Figure 2 The blocking structure 7 includes a block 701 that can move up and down inside the column 2. An inclined surface is provided on the block 701. The positioning pin 5 slides in contact with the block 701 through the inclined surface. The inclined surface of the block 701 can reduce the friction force of the block 701 on the positioning pin 5. The block 701 is located at one end inside the column 2 and is movably abutted against a spring 702. The spring 702 can drive the block 701 to move. The block 701 is located at the center of one end inside the column 2 and is fixedly embedded with a pull rope 703.

[0025] The working principle that can improve the efficiency of mold turning: the personnel first installs the rammed silicon carbide reduction tank into the turning frame 3, and then the personnel pulls the block 701 on the upper side upwards through the pull rope 703, so that the block 701 on the upper side moves to the inside of the column 2. At this time, the positioning pin 5 can be rotated out from the limiting rotation groove 6 on the upper side. When the positioning pin 5 rotates to the limiting rotation groove 6 on the lower side, the positioning pin 5 squeezes the block 701 through the inclined surface of the block 701, so that the block 701 on the lower side automatically enters the inside of the column 2. When the positioning pin 5 is separated from the block 701, the block 701 will be reset under the drive of the spring 702, and cooperate with the limiting rotation groove 6 to block the positioning pin 5, so that the turning frame 3 can be quickly and automatically positioned, and the personnel do not need to perform other actions, thereby effectively improving the mold turning efficiency of the silicon carbide reduction tank.

[0028] In this embodiment: during the rotation of the flip frame 3 through the rotating shaft 4, the multiple pins 801 located on the outside of the rotating shaft 4 will be repeatedly embedded in the rotating shaft 4 under the drive of the spring 2 803, increasing the rotation resistance of the rotating shaft 4, thereby effectively reducing the rotation speed of the flip frame 3, preventing the positioning pin 5 from hitting the column 2 under the inertia of the flip frame 3, and preventing the high silicon carbide reduction tank from vibrating and breaking.
