[0031] When in use, the two telescopic ends of the bidirectional electric telescopic rod 9 move synchronously to drive the inverted V-shaped liquid guiding groove 10 to move to the same side, so that the center position of the inverted V-shaped liquid guiding groove 10 is offset from the liquid outlet of the crucible 2, so that the alloy liquid in the crucible 2 can only flow into the mold from one side of the inverted V-shaped liquid guiding groove 10 when pouring out, and the alloy liquid in the crucible 2 is directly injected into the mold through the inverted V-shaped liquid guiding groove 10 after being poured out, which can effectively shorten the flow distance of the alloy liquid and avoid solidification of the alloy liquid during flow, thereby affecting the fluidity of the alloy liquid.

[0033] When the inverted V-shaped liquid guide groove 10 moves to one side, the push plate 18 installed at one end will apply a thrust to the storage spring 21. At this time, the limit block 25 at the bottom end of the trapezoidal block 24 abuts against the end of the rack sleeve 19, so that the rack sleeve 19 will not move. After the guide rod 26 installed on the push plate 18 abuts against the inclined surface of the trapezoidal block 24, the end of the guide rod 26 will squeeze the trapezoidal block 24 to move upward, so that the limit block 25 installed at the bottom end of the trapezoidal block 24 moves upward accordingly, so that the limit block 25 no longer limits the end of the rack sleeve 19.

After the guide rod 26 installed on the push plate 18 abuts against the inclined surface of the trapezoidal block 24, the end of the guide rod 26 will squeeze the trapezoidal block 24 to move upward, so that the limit block 25 installed at the bottom end of the trapezoidal block 24 moves upward accordingly, so that the limit block 25 no longer limits the end of the rack sleeve 19. At this time, the rack sleeve 19 will move outward under the elastic force of the storage spring 21, so that the rack sleeve 19 can drive the worm 15 to rotate through the transmission gear 17 and the one-way bearing 16, so that the worm The rod 15 can drive the worm gear 13 meshing with it to rotate, so that the worm gear 13 drives the feeding tray 29 to rotate 90 degrees through the rotating shaft 12, so that the feeding tray 29 can deliver the empty mold from one end of the conveyor belt 5 to the pouring position through the receiving trough 30, and deliver the mold after pouring to the other end of the conveyor belt 5, so that the conveyor belt 5 can transport the mold after pouring to the cooling device to wait for cooling and then take out the alloy part; this device can achieve the effect of the alloy liquid in the pouring process without manual loading and unloading of the mold, and through the inverted V-shaped liquid guide groove 10 that can be moved left and right to switch to guide the alloy liquid in different directions, it can achieve the effect of continuous pouring of the molds placed on both sides of the crucible 2, thereby improving the pouring efficiency.
