[0042] Specifically, the rotating rod 4 includes a rotating threaded rod 41 and a rotating bare rod 42; there are three rotating threaded rods 41; the driving device includes a rotating shaft and a motor; the rotating threaded rod 41 and the rotating bare rod 42 pass through the rotating groove 312, and pass through the mold frame 2 and are connected to the rotating shaft on the lower side of the mold frame 2, and the rotating shaft is connected to the motor; under the drive of the motor, the motor drives the rotating shaft to rotate, and the rotating shaft drives the rotating threaded rod 41 to rotate, and the rotating threaded rod 41 rotates to connect the rotating groove 312 so that the transmission channel 31 rises or falls along the axis of the rotating rod 4.

[0043] Specifically, the rotating bare rod 42 is one, has no threads on the outer periphery, and is close to the slag extraction pipe sleeve 51, and is inserted into the rotating groove 312 with a smooth inner wall; the middle part of the rotating bare rod 42 is fixedly connected to the rotating ring 1, and the outer periphery of the rotating slag extraction pipe sleeve 511 is fixedly connected to the rotating ring 2; the outer periphery of the rotating ring 1 is rotatably connected to one end of the conveyor belt, and the other end of the conveyor belt is rotatably connected to the rotating ring 2; under the drive of the motor, the motor drives the rotating shaft to rotate, and the rotation drives the rotating bare rod 42 to rotate, and the rotating bare rod 42 passes through the conveyor belt, driving the rotating slag extraction pipe sleeve 511 to rotate, and the rotating slag extraction pipe sleeve 511 drives the elastic slag extraction pipe sleeve 512 to rotate; in combination with the dividing surface 513 and the strip-shaped mouth 5121, the cleaning range of the slag extraction pipe sleeve 51 can be expanded, and the cleaning can be cleaner.

[0044] Specifically, the mold core 1 is provided with ventilation holes 11 near both ends of the sliding groove 21. Part of the conveying pipe 3 is contained in the ventilation hole 11, and the distance between the end of the transmission channel 31 located in the mold core 1 and the end of the ventilation hole 11 is greater than or equal to the distance that the ventilation valve plate 33 is flipped upward; a ventilation hole is provided at the bottom of the mold core 1; the end of the ventilation hole 11 is connected with the ventilation hole, and the wind in the conveying pipe 3 can pass through the ventilation hole vertically into the groove of the mold frame 2 to achieve the effect of ventilation and cooling.

[0045] Working principle: the transmission channel 31 is located at the end of the sliding groove 21 and is connected to the vacuum cleaner pipe, and the vacuum cleaner pipe is connected to the vacuum cleaner; the ventilation valve 33 is located at the end of the transmission channel 31 inside the mold core 1. When there is no wind, the end of the transmission channel 31 is in a closed state; the end of the transmission channel 31 is at a certain distance from the end of the vent hole 11 inside the mold core 1, and this distance is greater than or equal to the length of the ventilation valve 33; the valve plate 321 is located just below the air outlet at the bottom end of the valve tube 322; it is in a naturally drooping state when there is no wind; when the vacuum cleaner connected to the vacuum cleaner pipe starts working, only the strip at the slag extraction pipe sleeve 5 is open. The opening 5121 becomes the entrance for the vacuum cleaner pipe to suck in external impurities; the air at the strip opening 5121 will enter the transmission channel 31 through the slag extraction pipe sleeve 5 and finally enter the vacuum cleaner pipe; the outer surface of the mold core 1 corresponding to the strip opening 5121 will, under the action of suction, suck the remaining debris and accumulated dust on the outer surface of the mold core 1 into the slag extraction pipe sleeve 5; the valve plate 321 will also be flipped backward under the action of suction, so that the air outlet opened by the valve pipe 322 is not blocked; the ventilation valve 33 will also be more tightly fitted with the end of the transmission channel 31 under the action of suction, finally achieving the effect of the vacuum cleaner cleaning the outer surface of the mold core 1;

[0046] The slag extraction sleeve 51 includes a rotating slag extraction sleeve 511 and an elastic slag extraction sleeve 512. The rotating slag extraction sleeve 511 is used to be rotatably connected to the valve assembly 32; at the same time, it is fixedly connected to the elastic slag extraction sleeve 512. The dividing surface 513 in the elastic slag extraction sleeve 512 divides the internal space into multiple fan shapes, which are consistent with the air outlet shape at the bottom end of the valve pipe 322; the bottom of the dividing surface 513 is composed of multiple layers of strips, like a broom, which has good sealing performance and can also play a certain cleaning role on the bottom end of the valve pipe 322. When the dividing surface 513 rotates to the air outlet shape at the bottom end of the valve pipe 322, the impurities swept by the strips at the bottom end of the dividing surface 513 fall into The transmission channel 31 is sucked away; when the fan-shaped space is misaligned with the tuyere-shaped portion at the bottom of the valve tube 322, under the action of suction, the range of impurities cleaned by the strip opening 5121 is expanded, and the outer surface of the mold core 1 is cleaned more comprehensively; the elastic slag extraction pipe sleeve 512 and the dividing surface 513 are made of flexible silicone materials, which are resistant to high temperatures and have good elasticity; with the built-in spring; when the mold is closed, the elastic slag extraction pipe sleeve 512 is squeezed by the opposite mold and begins to compress until it is flush with the sliding groove 21; after separation, the spring automatically stretches, causing the elastic slag extraction pipe sleeve 512 to expand; the outer surface of the mold core 1 can be cleaned and slag removed at any time. Example

[0047] Cooling the mold core 1 and mold base 2;

[0048] The motor starts; it drives the rotating shaft to rotate, and the rotating shaft drives the rotating rod 4 to rotate; the threaded rod 41 is rotated to rotate the connected rotating groove 312, so that the transmission channel 31 rises or falls axially along the rotating rod 4, so that the conveying tube 3 can drive the mold core 1 to move axially along the rotating rod 3, so that the mold core 1 is separated from the mold frame 2; the protruding teeth 311 on both sides of the transmission channel 31 cross-insert with the protruding teeth on the side walls of the sliding groove 21, preventing the transmission channel 31 from falling off the sliding groove 21, ensuring stability during movement; because it is the rotating shaft that drives the rotating rod 4 to rotate, thereby causing the conveying tube 3 to move axially along the rotating rod 4, when the rotating shaft stops working, the conveying tube 3 will not automatically fall off even in the vertical direction;

[0049] The dust collector pipe connected to the transmission channel 31 is switched to supply air to the transmission channel 31. The transmission channel 31 is provided with multiple filters 313 in the part between the valve assembly 32 and the ventilation valve 33. When air is supplied to the transmission channel 31, some dust or debris will inevitably remain in the transmission channel 31. The filter 313 can filter out these impurities, so that the air transmitted to the groove of the mold frame 2 is free of impurities, thereby avoiding contamination of the groove. At the same time, since the air enters from the transmission channel 31, the naturally drooping valve plate 321 will flip forward under the action of wind, thereby blocking the air outlet at the bottom end of the valve pipe 322, avoiding the wind from being transmitted to the outer surface of the mold core 1 through the valve assembly 32 and contaminating the outer surface of the mold core 1. The ventilation valve 33 is blown open by the action of wind, allowing the wind to enter the vent 11 in the mold core 1 and blow into the groove of the mold frame 2 through the ventilation holes at the bottom of the mold core 1, thereby performing ventilation and cooling.

[0050] When the mold core 1 is not separated from the mold frame 2 and is in the mold closing state, low-temperature gas for cooling can also be introduced from the transmission channel 31, which helps to speed up the cooling speed of the mold core 1 and the mold frame 2; speed up the molding speed of the casting when the mold is closed; and improve work efficiency. Example

[0051] On the basis of the separation of the mold core 1 from the mold frame 1 in the second embodiment, the mold core 1 can be dusted;

[0052] Since the conveying pipe 3, the mold core 1 and the slag extraction channel 5 all move at the same time, the positional relationship between the conveying pipe 3, the mold core 1 and the slag extraction channel 5 does not change; when the conveying pipe 3 is located at the end of the sliding groove 21 and is switched to a vacuum cleaner pipe, the mold core 1 can be dusted.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
