Obviously, the described embodiments are only a part of the embodiments of the present application.

[0015] Embodiment one: graphite crucible mold cavity release agent automatic spraying and mold cavity raw material automatic shaping device. The chain plate conveyor 1 is horizontally placed on the ground and transports the graphite crucible mold 2 from front to back. The sliding groove 5 is fixed on the ground at the right side thereof, the Z-shaped support 3 bottom block is embedded in the sliding groove 5, the horizontal hydraulic cylinder 6 is fixed at the top right side of the sliding groove 5, the telescopic shaft is connected with the right bottom of the Z-shaped support 3. The vertical hydraulic cylinder 4 is installed at the top of the Z-shaped support 3, the telescopic shaft penetrates through the Z-shaped support 3 and connects the motor box 7, the servo deceleration motor 8 is fixed in the motor box 7, the bottom surface is provided with the fixed disc 15, the output shaft of the servo deceleration motor 8 penetrates through the fixed disc 15 and is installed with several pieces of blades 14, the top of the blade 14 and the bottom of the fixed disc 15 are spaced apart by 0.5 cm. The fixed disc 15 is inlaid with 10 spray heads 17, the release agent container 11 is fixed inside the Z-shaped support 3, the water pump 9 is installed on the left side wall thereof, the liquid suction port is connected with the liquid suction pipe 10 which extends into the release agent container 11, the pump liquid end is connected with the liquid discharge hose 12. The spray head 17 liquid inlet port is connected with the manifold 16, the top end of the manifold 16 is connected with the annular pipe 13, the end of the liquid discharge hose 12 extends into the annular pipe 13, the liquid level sensor is fixed on the side wall of the inner cavity of the release agent container 11, and the top side wall is provided with a liquid supplement port. The motor box 7 is provided with a through hole at the bottom, and a bearing is installed for the rotation of the output shaft of the servo deceleration motor 8.

[0016] When working, the chain plate conveyor 1 transports graphite crucible molds 2, when the molds reach the designated position, the transverse hydraulic cylinder 6 pushes the Z-shaped support 3 to move left and right, so that the vertical hydraulic cylinder 4 is coaxial with the crucible. The vertical hydraulic cylinder 4 is lowered, before feeding, the water pump 9 works, the demolding agent is extracted from the demolding agent container 11, uniformly sprayed into the mold through the liquid discharge hose 12, the annular pipe 13, the manifold 16 and the spray head 17. After that, the vertical hydraulic cylinder 4 is lifted again, the raw material is put into the mold, the vertical hydraulic cylinder 4 is pressed again, the servo reducer motor 8 is started, the blade 14 is slowly rotated during the pressing process, and the raw material in the mold is leveled to realize shaping.

[0017] In another production area, the device is also arranged. The chain plate conveyor 1 transports graphite crucible molds 2 in a set direction, the sliding groove 5 and the Z-shaped support 3 are not changed, the transverse hydraulic cylinder 6 controls the Z-shaped support 3 to move left and right, so that the vertical hydraulic cylinder 4 can be coaxial with the crucible. The motor box 7 connected with the telescopic shaft of the vertical hydraulic cylinder 4 is normally installed with the servo reducer motor 8, the outer circle of the fixed disc 15 is inlaid and fixed with 12 spray heads 17, and the distance between the top of the blade 14 and the bottom of the fixed disc 15 is 0.8 cm. The demolding agent container 11 is filled with demolding agent, the water pump 9 extracts the demolding agent through the liquid suction pipe 10, delivers it to the annular pipe 13 through the liquid discharge hose 12, and then distributes it to each spray head 17 through the manifold 16.

[0018] During production, the chain plate conveyor 1 transports the mold, after reaching the position, the transverse hydraulic cylinder 6 pushes the Z-shaped support 3 to adjust the position, the vertical hydraulic cylinder 4 is lowered, the water pump 9 is opened, and the demolding agent is uniformly sprayed into the mold. Subsequently, the vertical hydraulic cylinder 4 is lifted, the raw material is put in, and when it is pressed again, the servo reducer motor 8 drives the blade 14 to rotate, which levels the raw material during the pressing process, and completes the shaping operation.

[0019] In example three, the chain plate conveyor 1 of the device continuously transports graphite crucible molds 2. The Z-shaped support 3 can flexibly move left and right under the action of the sliding groove 5 and the transverse hydraulic cylinder 6, so as to ensure that the vertical hydraulic cylinder 4 is coaxial with the crucible. The motor box 7 connected with the telescopic shaft of the vertical hydraulic cylinder 4 is normally installed with the servo reducer motor 8, the output shaft of the servo reducer motor 8 penetrates the fixed disc 15 to connect the blade 14, and the distance between the top of the blade 14 and the bottom of the fixed disc 15 is 1.0 cm. The outer circle of the fixed disc 15 is inlaid and fixed with 11 spray heads 17, and a liquid level sensor is arranged in the demolding agent container 11. When the liquid level is lower than the set value, the demolding agent is supplemented through the liquid supplement port on the top side wall. The water pump 9 extracts the demolding agent through the liquid suction pipe 10, delivers it to the annular pipe 13 through the liquid discharge hose 12, and then distributes it to the spray head 17 through the manifold 16.

[0020] When the device is running, the chain plate conveyor 1 transports the mold to the designated position, the transverse hydraulic cylinder 6 pushes the Z-shaped support 3 to adjust the position, the vertical hydraulic cylinder 4 is lowered, and the water pump 9 works to uniformly spray the release agent into the mold. After the vertical hydraulic cylinder 4 is lifted, the raw materials are poured in, and when it is pressed down again, the servo reducer motor 8 drives the blade 14 to rotate, which smoothes the raw materials inside the mold during the pressing process, achieving shaping.

[0021] According to the above-mentioned preferred technical solution, the working process of the technical solution is described: after the chain plate conveyor 1 is started, it continuously transports the graphite crucible mold 2 from front to back. When the graphite crucible mold 2 is transported to the designated position, the transverse hydraulic cylinder 6 starts to work. Since the bottom surface of the Z-shaped support 3 is fixed with a sliding block that is adapted to slide in the sliding groove 5, the extension and retraction of the extension shaft of the transverse hydraulic cylinder 6 pushes the Z-shaped support 3 to move left and right on the sliding groove 5, so that the vertical hydraulic cylinder 4 installed on the top of the Z-shaped support 3 is coaxial with the graphite crucible mold 2. At this time, the extension and retraction shaft of the vertical hydraulic cylinder 4 is lowered, driving the motor box 7 to move downward, and the fixed disc 15 fixedly connected to the bottom surface of the motor box 7 also descends. Before the graphite crucible mold 2 is fed, the water pump 9 starts to work. The water pump 9 draws the release agent from the release agent container 11 through the liquid suction pipe 10 connected to the liquid suction port, and then delivers the release agent to the annular pipe 13 through the liquid discharge hose 12 connected to the pump liquid end. Since the liquid inlet ports of the 10-12 spray heads 17 embedded on the outer surface of the fixed disc 15 are all connected with the manifold 16, the top end of the manifold 16 is connected with the annular pipe 13, and the end of the manifold 16 away from the spray head 17 is in communication with the inner space of the annular pipe 13, and the port of the liquid discharge hose 12 away from the water pump 9 is in communication with the inner space of the annular pipe 13, so the release agent will be distributed from the annular pipe 13 to each spray head 17 through the manifold 16, and then uniformly sprayed into the graphite crucible mold 2 through the spray head 17.

[0022] After the spraying of the release agent is completed, the telescopic shaft of the vertical hydraulic cylinder 4 is lifted again, driving the motor box 7 and the fixed disc 15 to rise, and then the raw materials are poured into the graphite crucible mold 2 which has been sprayed with the release agent, and then the telescopic shaft of the vertical hydraulic cylinder 4 is pressed again, so that the fixed disc 15 and the blades 14 installed below the fixed disc 15 enter the graphite crucible mold 2, and at the same time the servo reduction motor 8 fixed in the inner cavity of the motor box 7 starts to work, the output shaft of the servo reduction motor 8 penetrates the fixed disc 15 to drive several blades 14 to rotate, and the blades 14 rotate slowly during the pressing process to smooth the raw materials in the mold, thereby realizing the shaping of the raw materials. The bottom surface of the motor box 7 is provided with a through hole for the output shaft of the servo reduction motor 8 to penetrate and rotate, and a bearing adapted to the output shaft of the servo reduction motor 8 is installed in the through hole to ensure the stable rotation of the output shaft of the servo reduction motor 8. The top surface of the blade 14 is spaced apart from the bottom surface of the fixed disc 15 by a distance of 0.5-1.0 cm to avoid interference between the blade 14 and the fixed disc 15 during rotation. In addition, the liquid level sensor fixed on the inner cavity side wall of the release agent container 11 can monitor the liquid level of the release agent in real time, and when the liquid level is too low, the release agent can be supplemented through the liquid supplementing port provided on the top side wall of the release agent container 11.

[0023] The foregoing merely describes some exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present application.
