[0006] By adopting the above technical scheme, a threaded rod is provided on the mounting frame, and two support plates that can slide up and down are installed on the threaded rod. The first cleaning mechanism and the second cleaning mechanism are respectively arranged on the two support plates. The first push rod is started to extend, driving the cleaning member to extend from one side of the workbench to above the mold cavity, adjusting the support plate corresponding to the first cleaning mechanism, driving the cleaning member to enter the mold cavity, starting the motor to drive the cleaning member to rotate, so as to clean the residue in the mold cavity of the mold. After the cleaning member brushes the cleaning, the first push rod retracts and drives the cleaning member to reset; the second push rod is started to extend, driving the nozzle to move from one side of the workbench to the other side, and the air pump is started at the same time, so that the air nozzle can clean the residue on the workbench surface and the residue dropped by the friction of the cleaning member. The second push rod can drive the air nozzle to move back and forth above the workbench. The air nozzle is tilted, so that the residue can be blown in the same direction, and the residue can be easily blown off, which is convenient for subsequent cleaning. The first cleaning mechanism is used to clean the mold cavity, and the second cleaning mechanism is used to clean the entire workbench surface. The second cleaning mechanism can work simultaneously with the first cleaning mechanism or in steps. The two adjust the working order according to actual cleaning needs, and the cleaning effect is good.

The mold cavity can be provided with a single or multiple first cleaning members on the fixed disk according to the cleaning requirements. The multiple cleaning members can be relatively arranged, and the design is reasonable. When the mounting column head enters the mounting hole through the channel, the baffle is pushed open and retracted into the fixed disk, and the spring in the baffle is compressed, and the mounting hole is opened. When the mounting column head enters the mounting hole, the spring is reset, driving the baffle to extend to close the mounting hole, so as to prevent the mounting column head from detaching from the fixed disk when the fixed disk rotates.

The diameter of one end of the column head is larger than the diameter of the connecting rod, so that one end of the second cleaning member can be restricted on the connecting rod, and the column head can be detached from the connecting rod to facilitate the installation of the second cleaning member.

[0013] The utility model is further configured as follows: the air pump and the air nozzle are arranged at the telescopic end of the second push rod, and the air nozzle is inclined toward the extending direction of the second push rod and the inclination angle range is 30-60°.

[0014] With the above further configuration, the air pump and the air nozzle are both arranged at the telescopic end of the second push rod, and the length of the conducting tube between the air pump and the air nozzle at the retracted end prevents the excessively long conducting tube from falling to the workbench and contacting the residue and blocking the gas blown out of the air nozzle during the retraction of the second push rod, thereby affecting the cleaning effect.

DETAILED DESCRIPTION

[0021] like Figure 1-5 As shown, a self-cleaning mold comprises a workbench 1, a first cleaning mechanism 2, and a second cleaning mechanism 3. A mounting frame is fixedly provided on the workbench 1, and the first cleaning mechanism 2 and the second cleaning mechanism 3 can be slid up and down on the mounting frame respectively. A mold cavity 11 is provided on the workbench 1. The first cleaning mechanism 2 comprises a cleaning member that can be extended into the mold cavity 11, a motor 23 for driving the cleaning member to rotate, and a first push rod 24 for driving the cleaning member to move laterally. The cleaning member is fixed on a fixed disk 25, and the motor 23 drives the cleaning member to rotate in the mold cavity 11 via the fixed disk 25. The cleaning member comprises a first cleaning member 21 for cleaning the side wall of the mold cavity 11 and a second cleaning member 22 for cleaning the bottom of the mold cavity 11. One end of the first cleaning member 21 is connected to the fixed disk 25, and the other end is connected to the second cleaning member 22. The second cleaning mechanism 3 comprises an air pump 31, an air nozzle 32 connected to the air pump 31, and a second push rod 33 for driving the air nozzle 32 to move telescopically. The air nozzle 32 is arranged at an angle.

[0022] A threaded rod is provided on the mounting frame, and two support plates that can slide up and down are installed on the threaded rod. The first cleaning mechanism 2 and the second cleaning mechanism 3 are respectively arranged on the two support plates. The first push rod 24 is started to extend, driving the cleaning member to extend from one side of the workbench 1 to the top of the mold cavity 11, and the support plate corresponding to the first cleaning mechanism 2 is adjusted to drive the cleaning member to enter the mold cavity 11. The cleaning member can be a brush or a sponge. The motor 23 is started, and the first cleaning member 21 located below the fixed plate 25 can move circumferentially along the inner wall of the mold cavity 11 to clean the residual value of the inner wall of the mold cavity 11. The second cleaning member 22 is hinged to the bottom of the first cleaning member 21. When the support plate corresponding to the first cleaning mechanism 2 descends, the second cleaning member 22 contacts with the bottom of the mold cavity 11. Driven by the first cleaning member 21, the second cleaning member 22 moves in the mold cavity 11 The bottom of the mold cavity 11 is rotated to clean the residue at the bottom of the mold cavity 11. After the cleaning brush is cleaned, the corresponding support plate is raised to drive the cleaning part to exit the mold cavity 11, and the first push rod 24 is retracted to drive the cleaning part to reset; the second push rod 33 is started to extend, driving the nozzle 32 to move from one side of the workbench 1 to the other side, and the air pump 31 is started at the same time, so that the air nozzle 32 can clean the residue on the workbench 1 and the residue dropped by the friction of the cleaning part. If the second cleaning mechanism 3 is located above the first cleaning part 21 structure, the cleaning part can also be blown to clean. The second push rod 33 can drive the air nozzle 32 to move back and forth above the workbench 1. The air nozzle 32 is tilted, which can make the residue blow in the same direction, easily blow off the residue, and facilitate subsequent cleaning. The telescopic stroke of the second push rod 33 is greater than the telescopic stroke of the first push rod 24. The second push rod 33 needs to drive the air nozzle 32 to blow and clean the entire workbench 1. The first push rod 24 only needs to drive the cleaning part to move horizontally to the top of the mold cavity 11. The first cleaning mechanism 2 is used to clean the mold cavity 11, and the second cleaning mechanism 3 is used to clean the entire workbench 1 surface. The second cleaning mechanism 3 can work simultaneously with the first cleaning mechanism 2 or in steps. The two adjust the working order according to actual cleaning needs, and the cleaning effect is good.

[0023] like Figure 1-5As shown, the motor 23 is arranged at the end of the first push rod 24, and the output shaft of the motor 23 is connected to the fixed disk 25. The fixed disk 25 is circumferentially provided with a plurality of mounting holes 251 for mounting the first cleaning member 21 and channels 252 corresponding to the mounting holes 251. The channels 252 connect the mounting holes 251 with the outside world. The channels 252 can be arranged along the radial direction of the fixed disk 25, or can be arranged in an L shape. The L-shaped channel 252 can prevent the first cleaning member 21 from being thrown out of the fixed disk 25. The motor 23 drives the fixed disk 25 to rotate, thereby driving the first cleaning member 21 installed on the outer periphery of the fixed disk 25 to make a circumferential movement to achieve cleaning of the side wall of the mold cavity 11. The mold cavity 11 can be provided with a single or multiple first cleaning members 21 on the fixed disk 25 according to the cleaning requirements. The multiple cleaning members can be arranged relatively to each other, and the design is reasonable. The top of the first cleaning member 21 is provided with a mounting column head 211 adapted to the mounting hole 251. The top diameter of the mounting column head 211 is larger than the inner diameter of the mounting hole 251, so as to prevent the first cleaning member 211 from separating from the fixed disk. A stopper 253 which can limit the mounting column head 211 is provided at one end of the channel 252 near the mounting hole 251. A spring is provided in the stopper 253, which can be retracted and arranged in the fixed disk 25. The stopper 253 can be arranged separately or relatively. A buffer can be provided on the side where the stopper 253 extends out of the fixed disk 25. When the stopper 253 is extended, the buffer can play a role of buffering and silencing. When the mounting column head 211 enters the mounting hole 251 through the channel 252, the stopper 253 is pushed open and retracted into the fixed disk 25. The spring is compressed and the mounting hole 251 is opened. When the mounting column head 211 enters the mounting hole 251, the spring is reset, driving the stopper 253 to extend to close the mounting hole 251, so as to prevent the mounting column head 211 from separating from the fixed disk 25 when the fixed disk 25 rotates. The structure is simple.

[0024] like Figure 3 As shown, a connecting rod 212 is vertically provided at the bottom of the first cleaning member 21, and a connecting hole 221 is provided at one end of the second cleaning member 22 corresponding to the connecting rod 212. The connecting hole 221 is circular, and the second cleaning member 22 can rotate perpendicular to the first cleaning member 21 to clean the bottom of the rectangular mold cavity 11. A column head is provided at the end of the connecting rod 212 to limit the second cleaning member 22 from escaping. The diameter of one end of the column head is larger than the diameter of the connecting rod 212, so that one end of the second cleaning member 22 can be limited to the connecting rod 212. The column head can be detached from the connecting rod 212 to facilitate the installation of the second cleaning member 22.

[0025] like Figure 1As shown, the air pump 31 and the air nozzle 32 are arranged at the telescopic end of the second push rod 33. The length of the conducting tube between the air pump 31 and the air nozzle 32 at the retracted end prevents the excessively long conducting tube from falling to the workbench 1 and contacting the residue and blocking the gas blown out by the air nozzle 32 during the retraction of the second push rod 33, thereby affecting the cleaning effect. The air nozzle 32 is inclined in the direction in which the second push rod 33 extends and the inclination angle range is 30-60°. Compared with traditional vertical air blowing cleaning, it can efficiently blow off the residue on the workbench 1 and has a good cleaning effect.

[0026] In another embodiment, if Figure 4 As shown, a curved connecting rod 212 is provided at the bottom of the first cleaning member 21, and the connecting rod 212 can be bent in an L shape or a U shape. A connecting waist hole 222 is provided at one end of the second cleaning member 22 corresponding to the curved connecting rod 212, and a movable gap is provided in the connecting waist hole 222, so that the second cleaning member 22 can rotate smoothly relative to the first cleaning member 21, and the second cleaning member 23 can be rotated relative to the first cleaning member 21 on a vertical plane, so that more angles are formed between the second cleaning member 22 and the first cleaning member 21, and the bottom of various mold cavities 11 can be cleaned. A column head is provided at the end of the connecting rod 212 to limit the second cleaning member 22 from escaping. The diameter of one end of the column head is larger than the diameter of the connecting rod 212, so that one end of the second cleaning member 22 can be limited to the connecting rod 212, and the column head can be detached from the connecting rod 212 to facilitate the installation of the second cleaning member 22.
