[0027] Embodiment 1:

[0028] See also Figures 1 to 5 The utility model provides a mold cavity waste removal device, including a base plate 1 and a waste removal brush 6, which is mainly composed of a brush rod and a brush; the base plate 1 is evenly provided with upper through holes, which are distributed along a straight line and the number of which is set according to the width of the mold cavity; the upper through holes are all plugged with a transmission rod 5, and the middle part of the transmission rod 5 is fixedly installed with a driven gear 4, and adjacent driven gears 4 are meshed and assembled, and the lower end of the transmission rod 5 is installed with a waste removal brush 6; the upper end of the transmission rod 5 is installed with a retaining spring 9, which is located above the base plate 1, and the upper end of the transmission rod 5 is provided with a retaining groove for installing the retaining spring 9; a driving assembly for driving the driven gear 4 is provided on the lower side of the base plate 1, and one of the driven gears 4 can be rotated by the driving assembly, and all the transmission rods 5 and the waste removal brush 6 can be driven to rotate at the same time through transmission, and the rotation directions of adjacent waste removal brushes 6 are opposite.

[0029] Specifically, Figure 4 As shown, the driving assembly includes a reduction motor 2 and a driving gear 3. The reduction motor 2 is fixedly mounted on the lower surface of the base plate 1 through a support seat, and the driving gear 3 is fixedly mounted on the output end of the reduction motor 2. The driving gear 3 is meshed and assembled with one of the driven gears 4. After the reduction motor 2 is powered on, the driving gear 3 can be rotated, thereby driving one of the driven gears 4, preferably a driven gear 4 arranged in the center.

[0030] Specifically, the thickness of the driven gear 4 is at least 10 cm, so as to ensure that the torque transmission between the driven gears 4 will not fail when the transmission rod 5 moves up and down.

[0031] Specifically, Figure 1As shown, the base plate 1 is installed with a cover shell 12, and a lower through hole is opened at the bottom of the cover shell 12, and the lower through hole is plugged and assembled with the transmission rod 5; the cover shell 12 can isolate and protect the internal driven gear 4, drive components and other structures to prevent dust and other foreign matter from entering and affecting normal work, and also to prevent operators from getting close to rotating parts and causing injuries.

[0032] Specifically, Figure 2 As shown, a maintenance port is provided on the side wall of the cover 12, and a baffle 13 is hingedly connected to the maintenance port. A knob 14 for locking the baffle 13 is installed on the side wall of the cover 12; the maintenance port corresponds to the driven gear 4, and the baffle 13 can be flipped upward when the knob 14 is turned on, so as to facilitate the addition of lubricant to the driven gear 4. After completion, the baffle 13 is closed and the knob 14 is reset to lock the baffle 13.

[0033] Specifically, linear bearings 8 are fixedly installed inside the upper through hole and the lower through hole. The linear bearings 8 are existing components. The linear bearings 8 can reduce the friction of the transmission rod 5 when it moves inside. The transmission rod 5 can rotate inside the linear bearings 8 and can also move linearly along the linear bearings 8.

[0034] Specifically, a sleeve 7 is fixedly installed on the upper end of the waste removing brush 6, and radial through holes are opened in the sleeve 7 and the transmission rod 5, and bolts are passed through and locked in the aligned through holes; by removing the bolts, the sleeve 7 and the transmission rod 5 can be quickly connected and separated, thereby achieving the purpose of convenient replacement of the waste removing brush 6.

[0035] Specifically, a connecting screw hole 15 is opened on the top of the base plate 1, and the driving end of the driving machinery (such as a mechanical arm or an electric lead screw module and other components) used to move the device can be screwed and fixed to the connecting screw hole 15 by bolts.

[0036] The working method of this embodiment is as follows:

[0037] When in use, the device is first connected and installed on the driving end of the driving machine; after the mold is used and cooled, the driving machine drives the device to move to the top of the mold, and after the reduction motor 2 is energized, the driving gear 3 and the driven gear 4 can be driven to rotate the transmission rod 5 and the waste removal brush 6 at the same time, and the waste removal brush 6 will fall to the initial position at the bottom due to its own weight;

[0038] The driving machinery drives the device to move downward and move in an S shape on the horizontal plane, so that the rotating waste removal brushes 6 are against the mold cavity. The waste removal brushes 6 will be distributed according to the height of the mold cavity. The low part of the mold cavity will be against the drooping waste removal brush 6, and the high part of the mold cavity will push up the waste removal brush 6, so that the waste removal brush 6 can adaptively adjust the height along the cross-sectional shape of the mold cavity without affecting the rotation of the waste removal brush 6, thereby ensuring the waste removal effect. Afterwards, with the horizontal S-shaped movement of the driving machinery, the mold cavity can be fully cleaned of waste.
