[0029] A conical support seat 5 is arranged on the conical support spring 4, and the conical support seat 5 is a truncated cone structure. The conical support seat 5 is adapted to the conical support spring 4, and the conical support seat 5 is arranged on the inner side of the conical support spring 4, and the conical support seat 5 is fixedly connected to a part of the conical support spring 4; the casting mechanism also includes a casting device 2 and a sand mold 3, and the sand mold 3 is detachably arranged on the conical support seat 5; that is, the sand mold 3 can be placed on the conical support seat 5 and can be removed from the conical support seat 5.

[0030] The pouring device 2 is used to pour molten zirconium corundum into the sand mold 3. Specifically, the pouring device 2 includes a bracket assembly 21, and the support assembly consists of a support frame 211 and a connecting frame 212. The connecting frame 212 is fixedly connected to the support frame 211, and the support frame 211 is located on one side of the chain conveyor 1; a pouring device 22 is installed on the connecting frame 212, and a pouring head 23 is connected to the bottom of the pouring device 22. A liquid guide tube 24 is also connected to the pouring device 22, and the top of the liquid guide tube 24 is used to connect to an external electric melting device, so as to introduce molten zirconium corundum into the pouring device 22, and then the molten zirconium corundum can be discharged from the pouring head 23, and the pouring head 23 is located above the chain conveyor 1, and the pouring head 23 corresponds to the position of the arc groove 31 of the chain. In addition, the pouring head 23 is arranged at a position close to the middle of the chain conveyor 1.

[0031] In this embodiment, when any conveying chain plate 11 moves from the end of the chain plate conveyor 1 to the upper side and is in a horizontal state, and the conveying chain plate 11 is in a suitable position, the chain plate conveyor 1 is controlled to stop, and the sand mold 3 is clamped by an external manipulator or other device, and the sand mold 3 is placed on the conical support seat 5 corresponding to the chain plate; after the sand mold 3 is placed, the chain plate conveyor 1 works again to drive the sand mold 3 to move; in the above process, when the sand mold 3 moves to the bottom of the pouring head 23, the chain plate conveyor 1 is controlled to stop, and the pouring device 22 is controlled to make the pouring head 23 discharge the molten zirconium corundum, so that the molten zirconium corundum in the sand mold 3 can be poured into the pouring head 23. After the pouring is completed, the chain plate conveyor 1 works again; and during the operation of the chain plate conveyor 1, the conveying The chain plate 11 will vibrate. Since a conical support spring 4 is arranged in the conical groove 111, the conical support spring 4 supports the conical support seat 5. The conical support spring 4 can slow down the vibration of the conical support seat 5, so that the conical support seat 5 can vibrate less. Since the sand mold 3 is placed on the conical support seat 5, it is easy to cause the sand mold 3 to vibrate less, which helps to reduce the generation of bubbles in the zirconium corundum solution; and when the cast sand mold 3 moves to a suitable position near the end of the chain conveyor 1, the chain conveyor 1 is controlled to stop, and the sand mold 3 is clamped and transferred by an external manipulator or other device; in order to facilitate clamping by an external manipulator or other device, arc grooves 31 are provided on both sides of the sand mold 3, and the arc grooves 31 on both sides of the sand mold 3 are symmetrically arranged.

[0033] Embodiment 2

[0034] See also Figure 1-Figure 5 This embodiment is based on the first embodiment, and a cross slot 51 is provided at the center of the large end of the conical support seat 5; at the same time, a limiting block 32 is provided at the bottom of the sand mold 3, and the limiting block 32 is adapted to the cross slot 51; through the cooperation between the limiting block 32 and the cross slot 51, the sand mold 3 can be stably placed on the conical support seat 5; that is, when the sand mold 3 is clamped and placed by an external manipulator or other device in the first embodiment, the limiting block 32 at the bottom of the sand mold 3 is matched in the cross slot 51.

[0035] The limiting block 32 and the sand mold 3 are an integrally formed structure.

[0036] Embodiment 3

[0037] See also Figure 1-Figure 7 This embodiment is based on the second embodiment, and the pouring mechanism also includes two heat sinks 6, which are arranged on the top of the chain conveyor 1, the two heat sinks 6 are close to the middle of the chain conveyor 1, and the two heat sinks 6 are symmetrically arranged; the heat sink 6 is located on one side of the pouring head 23, and the sum of the lengths of the two sand molds 3 is less than the distance between the heat sink 6 and the pouring head 23.

[0038] A plurality of heat-conducting balls 7 are movably arranged on each heat sink 6, and the plurality of heat-conducting balls 7 are evenly spaced along the length direction of the heat sink 6; specifically, a rotating shaft 71 is passed through the center of each heat-conducting ball 7, and the rotating shaft 71 is vertically arranged, and the axis of the rotating shaft 71 is colinear with the vertical axis of the heat-conducting ball 7; the rotating shaft 71 is fixedly connected to the heat-conducting ball 7, and the two ends of the rotating shaft 71 are movably connected to the heat sink 6 through bearings; when the sand mold 3 is placed on the conical support seat 5, the sand mold 3 is poured with molten zirconium corundum, and the sand mold 3 is in a stationary state, the arc grooves 31 on both sides of the sand mold 3 correspond to the heat-conducting balls 7 of the two heat sinks 6 respectively; in addition, each heat-conducting ball 7 on one heat sink 6 is arranged in a one-to-one correspondence with each heat-conducting ball 7 on the other heat sink 6, and the diameter of the arc groove 31 is larger than the outer diameter of the heat-conducting ball 7.

[0039] That is, when the sand mold 3 moves between the two heat sinks 6, since the heat-conducting ball 7 is a spherical structure, the cooperation between the heat-conducting ball 7 and the arc groove 31 facilitates the sand mold 3 to be guided between the two corresponding heat-conducting balls 7, and the heat-conducting ball 7 contacts the arc groove 31; the heat-conducting ball 7 is made of a material with good thermal conductivity, such as copper; when the sand mold 3 moves between the two heat sinks 6, since the arc grooves 31 on both sides of the sand mold 3 contact the heat-conducting ball 7, the heat on the sand mold 3 can be transferred to the heat-conducting ball 7, and The friction between the arc groove 31 and the heat-conducting ball 7 is utilized to drive the heat-conducting ball 7 to rotate. The heat-conducting ball 7 disturbs the airflow around it during its rotation, so that the heat on the heat-conducting ball 7 is dissipated into the surrounding air. In addition, in order to facilitate the dissipation of the heat of the heat-conducting ball 7, heat dissipation ports 61 are provided on the top and side of the heat sink 6. The sand mold 3 is cooled and lowered to a certain extent by conducting heat to the sand mold 3, thereby further helping to reduce the generation of bubbles, and can further improve the molding quality of the zircon corundum brick.

[0040] In addition, in this embodiment, the sand mold 3 can be stopped by controlling the chain conveyor 1 only after it passes through the area between the two heat sinks 6, and the sand mold 3 can be clamped and transferred by an external robot or other device.
