The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0022] The present application embodiment discloses a sand core ingate cleaning device. Figure 1 As shown, the ingate cleaning device of the sand core includes a base plate 301 and a plurality of brushes 303, wherein the plurality of brushes 303 are vertically arranged on the base plate 301 according to the positions of the ingate and riser of the sand core, and the plurality of brushes 303 are respectively used to clean the ingate or riser corresponding to the sand core.

[0023] By using the ingate cleaning equipment in the technical solution, the brushes 303 are reasonably arranged on the base plate 301 according to the positions of the ingate and riser of the sand core, and then a hanger or a robot can be used to carry the sand core to the top of the base plate 301 through its clamp, and the precise position movement of the robot is utilized to align the ingate holes and risers on the sand core with each brush 303 respectively. Then, the robot drives the sand core to move vertically downward to insert each brush 303 into the ingate holes and risers of the sand core respectively, and reciprocates up and down to realize automatic cleaning of flaky sand burrs by the brush 303. Finally, the robot drives the sand core to move vertically upward to leave the brush 303 to complete the cleaning operation, thereby reducing the labor intensity of manually cleaning each ingate and riser of the sand core, improving the cleaning efficiency and cleaning effect of the ingate and riser of the sand core, and thereby improving the quality of the cast one-piece cylinder head.

[0024] Furthermore, the diameter of the brush 303 is 3-6 mm larger than the diameter of the ingrate hole or the riser to ensure stable cleaning of the flaky sandy burrs.

[0025] Furthermore, the bottom of the brush 303 can be mounted on the bottom plate 301 by welding or threading.

[0026] In some embodiments of the present invention, Figure 1 As shown, the ingrate cleaning device further includes a bracket 306 , and the bottom plate 301 is detachably connected to the top of the bracket 306 .

[0027] The bottom plate 301 is raised to a certain height by the bracket 306 , so that the robot can control the fixture to carry the sand core to the top of the bottom plate 301 to complete the cleaning of the inner runner hole and the riser.

[0028] It should be noted that one or more bottom plates 301 may be installed on the bracket 306 . When more than two bottom plates 301 are installed on the bracket 306 , the brushes 303 on each bottom plate 301 may be arranged specifically according to different sand cores.

[0029] Specifically, in this embodiment, two base plates 301 are installed on the bracket 306, and the multiple brushes 303 on one base plate 301 are arranged according to the ingate and riser of the chassis core, and the multiple brushes 303 on the other base plate 301 are arranged according to the ingate and riser of the upper cover core. Therefore, according to the different types of sand cores of the same one-piece cylinder head, the robot can control the fixture to carry the sand core to the corresponding base plate 301 to complete the cleaning of the ingate holes and risers.

[0030] In some embodiments of the present invention, Figure 1 As shown, a positioning pin 304 is provided on the top of the bracket 306 , a pin sleeve adapted to the positioning pin 304 is provided on the bottom plate 301 , and the bottom plate 301 is detachably connected to the bracket 306 via a screw 305 .

[0031] The base plate 301 and the bracket 306 are detachably connected by screws 305, which facilitates the replacement of the base plate 301 and the brush 303 thereon to adapt to different sand cores, thereby reducing the overall replacement cost of the inner runner cleaning equipment; the positioning pin 304 cooperates with the pin sleeve to position the base plate 301 on the bracket 306, which not only improves the installation efficiency of the base plate 301, but also improves the installation stability of the base plate 301 on the bracket 306.

[0032] It should be noted that the positioning pin 304 and the pin sleeve can be directly fixed on the bracket 306 and the bottom plate 301 respectively by welding.

[0033] In some embodiments of the present invention, Figure 1As shown, the ingrate cleaning device further includes a waste trolley 308, which is disposed below the bottom plate 301 and is used to collect burrs cleaned from the ingrate and riser of the sand core by the brush 303.

[0034] By collecting the cleaned burrs through the waste trolley 308, the scattering of debris on the ground can be reduced, the cleanliness of the working environment can be ensured, and it is convenient for the staff to centrally process the cleaned burrs of the ingates and risers.

[0035] It should be noted that a plurality of through holes 302 may be provided on the bottom plate 301 at positions offset from the brush 303 , so that the burrs cleaned by the brush 303 from the inner runner and riser of the sand core can fall directly into the waste cart 308 .

[0036] Furthermore, wheels 309 are installed at the bottom of the waste cart 308; and a handle 310 is installed at one side of the waste cart 308.

[0037] By using the handle 310 in conjunction with the wheel 309 , the staff can conveniently move the waste cart 308 to transfer the debris in the waste cart 308 , thereby reducing the labor intensity of the staff.

[0038] It should be noted that the wheels 309 include but are not limited to fixed wheels, universal wheels, etc., which are not limited here.

[0039] In some embodiments of the present invention, Figure 1 As shown, a cross bar 311 is installed on the bracket 306 , and after the waste cart 308 is pushed to a predetermined position below the bottom plate 301 by the handle 310 , the handle 310 contacts the cross bar 311 .

[0040] The waste trolley 308 is limited by the cross bar 311, which not only makes it convenient for the staff to quickly and accurately push the waste trolley 308 to the appropriate position, but also reduces the free movement of the waste trolley 308 during use and improves its stability.

[0041] In some embodiments of the present invention, Figure 1 As shown, the ingate cleaning device also includes a collecting hood 307, which is located below the base plate 301. The collecting hood 307 is mounted on a bracket 306, and the collecting hood 307 is used to guide the burrs cleaned by the brush 303 from the ingate of the sand core to the waste cart 308.

[0042] The scattered sand generated during the cleaning process at the bottom plate 301 can be accurately drained to the waste trolley 308 through the collecting cover 307, thereby improving the collection efficiency and accuracy of the scattered sand.

[0043] Specifically, in this embodiment, the collecting hood 307 includes a first guide plate and two second guide plates, wherein the top end of the first guide plate is connected to the bracket 306, and the bottom end is inclined to extend above the waste cart 308; the two second guide plates are opposite and spaced apart, the top end is connected to the bracket 306, and the bottom end is inclined to extend above the first guide plate; the two second guide plates and one first guide plate are overall in a U-shaped structure.

[0044] In some embodiments of the present invention, the brush 303 is made of nylon.

[0045] It can be understood that the brush 303 is composed of a hard rod located in the middle and a nylon wire connected to the outside of the hard rod, and the burrs are cleaned by the nylon wire.

[0046] In other embodiments, the brush 303 may also be made of other soft materials, and can be used to clean the burrs on the inner gate and the riser of the sand core, which is not limited here.

[0047] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
