However, because the mold groove of the injection molding machine has a certain depth, the bristles of the device are difficult to contact the bottom surface of the mold groove, so that part of debris particles and the like still have certain probability to remain in the mold groove, the cleaning effect is poor, and the production quality of injection molding products is influenced.

Although CN213107735U adopts the cooperation of spring and brush to adapt to the depth change of the mold groove, the interior of the mold with complex structure is still difficult to clean thoroughly due to the different shapes of the mold structures, and in addition, in the prior art CN108144879A, the cam is moved to move left and right while the cleaning device rotates, so as to expand the cleaning range of the mold, but the size of the cam determines the variation range of the mold cleaning, even if the cam is changed to adapt to the size of the mold, under the condition that the rotation speed of the cleaning device is not changed, the moving speed of different mold sizes is different, so that the cleaning degree of the mold is difficult to ensure, especially under the condition of being applied to large-size mold cleaning. When the cleaning device in the comparison document is used, the mold needs to be detached from the injection molding device and then installed on the cleaning device for cleaning, and the operation process is complicated. In view of this, we propose an injection molding device with a built-in ash removal brush and a method of using the same.

Example 2

This embodiment is different from embodiment 1 described above in that: the brushes 903 are arranged in a blocking mode and movably arranged on the outer side of the bottom surface of the lifting cylinder 902, a first magnetic block is arranged inside a brush rod of the brushes 903, the rotating cylinder 901 provided with the brushes 903 arranged in the blocking mode and the common rotating cylinder 901 are arranged at intervals, and a second magnetic block is embedded in the side wall of the common rotating cylinder 901.

In the technical scheme, the brushes 903 can be arranged in a plurality of pieces in a splicing manner, an elastic part can be fixedly connected between the brush rod and the inside of the lifting cylinder 902, so that the brushes 903 cannot be randomly displaced when contacting with a mold groove, in the process that a plurality of rotary cylinders 901 rotate simultaneously, the distance between a second magnetic block on the general rotary cylinder 901 and first magnetic blocks arranged on the brushes 903 of the two rotary cylinders 901 on two sides of the general rotary cylinder is always in a changing state, the magnetic force between the first magnetic blocks is constantly changed, further, the rotating angles of the brushes 903 arranged in blocks are also constantly changed when the brushes 903 arranged in blocks are subjected to the magnetic force, and the rotating angles of the brushes 903 arranged in blocks are also different, further, the brushes 903 arranged in blocks have diversified forms in the process of moving and rotating to clean the mold, so that the cleaning area range, the cleaning mode and the like of the brushes 903 are changed, the brushes 903 have complicated and diversified cleaning tracks, and are particularly suitable for cleaning areas with complicated internal structures of the mold.

Example 3

This embodiment is different from embodiment 1 described above in that: the brush 903 is arranged in a blocking mode and movably arranged on the outer side of the bottom surface of the lifting cylinder 902, a first magnetic block is arranged inside a brush rod of the brush 903, a second magnetic block is embedded in the side wall of the rotating cylinder 901, the second magnetic block can be an electromagnetic block, a controller is arranged in the injection molding device and used for controlling the work of the motor 401, the negative pressure pump 1204 and the electromagnetic block, a random number generation module is arranged in the controller, and each electromagnetic block is associated with a fixed number.

An injection molding apparatus with a built-in ash removal brush as claimed in any one of claims 1 to 8, wherein: the controller is used for controlling the work of the motor, the negative pressure pump and the electromagnetic blocks, the controller comprises a random number generation module, and each electromagnetic block is associated with one fixed serial number.

10. The use method of the injection molding device with the built-in dust removing brush as claimed in claim 8 or 9, wherein: the method comprises the following steps:

a) The telescopic ash cleaning mechanism moves for cleaning, a motor is started through a controller, and a sliding plate is driven to horizontally reciprocate on a supporting plate by virtue of chain wheel and chain transmission and sliding fit of a driving rod and a waist-shaped hole, so that a fixed plate and the telescopic ash cleaning mechanism are driven to horizontally reciprocate, and the horizontal moving cleaning of the telescopic ash cleaning mechanism is realized;

when the rotating drums are provided with the hairbrushes and the second magnetic blocks which are arranged in a blocking mode, turning to the step e);

d) The cleaning range and the cleaning mode of the brush are fixedly changed, the rotating drum rotates to change the distance between the first magnetic block and the second magnetic block, so that the brush is constantly rotated under the action of the changing magnetic force to constantly change the included angle between the brush and the lifting drum, and the brush has diversified cleaning tracks in the process of moving and rotating to clean the die;
