[0002] A track is a device used to connect a vehicle to the ground, bear the weight of the vehicle and transmit power to achieve driving. It is usually composed of a metal chain or belt and is installed on the lower part of military and civilian vehicles such as tanks, armored vehicles, excavators, and bulldozers. The design and material of the track can be adjusted according to different usage environments and requirements to provide the required traction, ground pressure and wear resistance.

[0003] In the production and processing of tracks, investment casting is often used. Investment casting, also known as lost wax casting, is a process for manufacturing precision castings. The melted casting solution is often not all used. After the mold is poured, it is necessary to wait for the track inside the mold to solidify and take out the formed track parts before pouring again.

[0026] The working principle of this utility model:

[0027] When the casting solution needs to be temporarily stored, the transmission motor 501 is started, and the output end of the transmission motor 501 drives the transmission gear 503 to rotate through the transmission sleeve 502. During the rotation of the transmission gear 503, the valve screw 2d is driven to rotate.

But it solidifies. When the casting solution needs to be used, the transmission motor 501 is started to reverse, driving the valve head 2b to move to the right, so that the valve head 2b is out of contact with the discharge port 2a, and the casting solution flows out. When the casting solution feeding speed needs to be accelerated, the cylinder 7 is started, and the output end of the cylinder 7 drives the transmission gear 503 to move upward through the connecting ring 8, and the transmission gear 503 is out of contact with the valve screw 2d. During the movement of the transmission gear 503, the transmission sleeve 502 is driven to move upward, so that the transmission sleeve 502 is stably connected with the pressing screw 601, and the transmission motor 501 is started. The output end of the transmission motor 501 drives the pressing screw 601 to rotate through the transmission sleeve 502. During the rotation of the pressing screw 601, the moving rod 602 is driven to move downward, thereby driving the pressing plate 604 to squeeze the casting solution, thereby accelerating the feeding speed of the casting solution.
