Description

Technical Field

[0001] This invention relates to the field of casting feeding technology for iron sand molds used in casting, specifically to a casting feeding device for iron sand molds used in casting robot parts. Background Technology

[0002] The intelligent robot industry is an important component of emerging industries and a core supporting industry for promoting the transformation and upgrading of the manufacturing industry and developing the digital economy. In the field of high-end robots, a mature system has been established for the research and development of shoulder joint shells and robotic arm casting, focusing on the precise matching and mass production application of lightweight, high-strength, and high-toughness materials.

[0003] Currently, iron sand molds are commonly used for casting robot components. To improve the casting quality of robot components, in addition to improving the quality of the iron sand mold itself, it is also necessary to effectively filter out slag and oxide inclusions contained in the casting material. Existing methods for removing slag and oxide inclusions from the casting material include installing high-temperature resistant filter media at the outlet of the ladle or installing foam ceramic filters at the pouring port of the iron sand mold. While this can achieve some degree of slag and oxide inclusion removal, the filtration rate is relatively low, making it difficult to further improve the casting quality of robot components.

[0004] Therefore, the research objective of this invention is to design a casting feeding device for a casting iron mold sand box for robot parts, which can effectively and significantly improve the filtration rate of slag and oxide inclusions contained in the casting material, thereby effectively improving the casting quality of robot parts, without affecting the normal pouring of the casting material. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the present invention provides a casting feeding device for a casting iron sand box for robot component casting, which can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this invention is: A casting feeding device for a sand mold box used for casting robot parts includes: The insulated material guide cylinder has a corresponding foam ceramic filter installed at the discharge end and is connected to the pouring port of the iron sand box. The side wall of the insulated material guide cylinder is provided with a corresponding material guide hole. A plug for controlling the opening and closing of the material guide hole is movably installed on the insulated material guide cylinder. A high-temperature resistant ceramic piston is movably installed inside the insulated material guide cylinder. A corresponding high-temperature resistant ceramic column is fixedly connected to the top of the high-temperature resistant ceramic piston facing upwards. The top of the high-temperature resistant ceramic column is connected to the external frame through a corresponding elastic element for buffering. The slag layer collection assembly includes ceramic spheres mounted on the high-temperature resistant ceramic column. The surface of each ceramic sphere has a grid-like distribution of several corresponding embedding grooves. Molten metal is poured into the inlet of the insulated feed cylinder. As the amount of molten metal increases, the high-temperature resistant ceramic piston, under its weight, descends to the upper part of the ceramic sphere within the insulated feed cylinder. Slag and oxides in the molten metal float to the top, forming a slag layer. Moving the plug externally opens the feed hole, allowing the molten metal to continue flowing into the insulated feed cylinder. The molten metal at the bottom of the slag layer flows through the feed hole and is filtered by the foam ceramic filter before being poured into the casting port of the iron mold sand box. When the material in the insulated feed cylinder decreases, the elastic element lifts the high-temperature resistant ceramic column and piston. The molten metal above the piston enters the feed hole, while the slag layer above the molten metal covers and fixes itself to the surface of the ceramic sphere.

[0007] The high-temperature resistant ceramic column is integrally formed with an annular mounting flange for supporting the ceramic sphere. The ceramic sphere is hollow, and its bottom end is sealed to the annular mounting flange. The hollow area of ​​the ceramic sphere is filled with numerous corresponding spherical ceramic damping particles for vibration reduction.

[0008] The top of the ceramic sphere has a corresponding filling hole, through which the spherical ceramic damping particles are filled into the hollow area of ​​the ceramic sphere.

[0009] The high-temperature resistant ceramic column is fitted with a counterweight cover plate for sealing the filling hole of the ceramic sphere.

[0010] The heat-insulating material guide cylinder is provided with a limiting protrusion located between the inlet and outlet of the material guide hole. When the high-temperature resistant ceramic piston moves down under the weight and abuts the limiting protrusion, the counterweight cover plate is located on the upper side of the inlet of the heat-insulating material guide cylinder.

[0011] The foam ceramic filter is circular in shape, and the diameter of the foam ceramic filter is smaller than the inner diameter of the limiting flange.

[0012] The bottom of the outer wall of the heat-insulating material guide cylinder is provided with a corresponding mating protrusion, which is detachably locked and installed onto the iron shell of the iron sand box by means of bolt locking.

[0013] The discharge end of the heat-insulating guide cylinder extends to the bottom side of the mating flange and is inserted into the pouring port of the iron sand box.

[0014] The plug body includes a plug body bolt screwed to the side wall of the heat-insulating material guide cylinder, and the inner end of the plug body bolt is fixedly installed with a corresponding high-temperature resistant ceramic sleeve by a fastening bolt.

[0015] The top of the high-temperature resistant ceramic column is integrally formed with a corresponding locking plate. The elastic element is a helical spring. The bottom of the helical spring is fixedly connected to a connecting plate that matches the locking plate. The connecting plate is locked onto the locking plate by bolt locking.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1) The present invention is provided with an insulated material guide cylinder installed at the pouring port of the iron sand box. The discharge end of the insulated material guide cylinder is equipped with a foam ceramic filter and a material guide hole is provided on its side wall. A plug for controlling the opening and closing of the material guide hole is movably installed on the insulated material guide cylinder. Then, a high temperature resistant ceramic piston is added inside the insulated material guide cylinder, and a high temperature resistant ceramic column and an elastic element are used to buffer the high temperature resistant ceramic piston. Finally, a scum layer collection component is added, which includes a ceramic ball set on the high temperature resistant ceramic column. The surface of the ceramic ball is evenly distributed with several corresponding embedded grooves in a grid pattern. During the casting process, molten metal is poured into the inlet of the insulated feed cylinder. As the amount of molten metal increases, the high-temperature resistant ceramic piston, under its own weight, descends to the upper part of the insulated feed cylinder where the ceramic sphere enters. This causes slag and oxide inclusions in the molten metal to float to the top, forming a slag layer. The piston is then moved outward to open the feed hole. As the molten metal continues to be poured in, the molten metal at the bottom of the slag layer flows through the feed hole and is filtered by a foam ceramic filter before being poured into the casting port of the iron mold sand box. This effectively achieves the desired consistency of the casting material. The process involves removing slag and oxide inclusions. Most importantly, during the pouring of molten metal, if human error causes a decrease in the material within the insulating feed cylinder, or if the material decreases near the end of the pouring process, the elastic element will lift the high-temperature ceramic column and piston. This allows the molten metal above the piston to enter the feed hole, maintaining the purity of the poured molten metal. The slag layer on top of the molten metal will then cover and fix onto the surface of the ceramic sphere. This effectively improves the filtration rate of slag and oxide inclusions in the casting material without affecting the normal pouring process, thus significantly improving the casting quality of the robot components.

[0017] 2) The high-temperature resistant ceramic column of this invention is integrally formed with an annular mounting flange for supporting the ceramic sphere. The ceramic sphere is hollow, and its bottom end is sealed to the annular mounting flange. Numerous corresponding spherical ceramic damping particles for vibration reduction are then filled into the hollow area of ​​the ceramic sphere. The frictional energy dissipation between the spherical ceramic damping particles can reduce the tumbling degree of the molten metal during casting to a certain extent, thereby helping to improve the flotation rate of slag and oxide inclusions in the molten metal and the stability of the formed slag layer, thus effectively improving the filtration rate of slag and oxide inclusions contained in the casting material.

[0018] 3) The top of the ceramic sphere of the present invention is provided with a corresponding filling hole. The spherical ceramic damping particles are filled into the hollow area of ​​the ceramic sphere through the filling hole to ensure that the spherical ceramic damping particles can be filled smoothly. At the same time, the filling hole of the ceramic sphere is closed by a counterweight cover plate, and the downward stroke of the high-temperature resistant ceramic piston is limited by a limiting protrusion to ensure that the counterweight cover plate is always located on the upper side of the feed port of the heat-insulating guide cylinder, thereby preventing the molten metal from entering the hollow part of the ceramic sphere during pouring, so as to prevent the friction energy dissipation between the spherical ceramic damping particles from being affected, and thus ensuring the practical effect of the present invention.

[0019] 4) The foam ceramic filter of the present invention is circular in shape, and the diameter of the foam ceramic filter is smaller than the inner diameter of the limiting protrusion, so as to ensure the convenience of the replacement operation of the foam ceramic filter, thereby effectively ensuring the practical effect of the present invention.

[0020] 5) The bottom of the outer wall of the thermal insulation guide cylinder of the present invention is provided with a mating flange. The mating flange is detachably locked and installed on the iron shell of the iron sand box by means of bolt locking. The discharge end of the thermal insulation guide cylinder extends to the bottom side of the mating flange and is inserted into the pouring port of the iron sand box. Under the premise of maintaining smooth pouring connection, the thermal insulation guide cylinder can be detachably installed, thereby effectively realizing the reusability of the present invention.

[0021] 6) The plug body of the present invention includes a plug body bolt screwed to the side wall of the heat-insulating material guide cylinder. The inner end of the plug body bolt is fixedly installed with a corresponding high-temperature resistant ceramic sleeve by a fastening bolt. With the intervention of the high-temperature resistant ceramic sleeve, the contact end between the plug body and the high-temperature molten metal does not undergo excessive deformation, thereby ensuring the stability of the plug body structure and its movement of the present invention, so as to further ensure the practical effect of the present invention.

The top of the high-temperature resistant ceramic column 7 is buffered and connected to the external frame through a corresponding elastic element 8. The slag layer collection component 9 includes ceramic spheres 901 disposed on the high-temperature resistant ceramic column 7. The surface of each ceramic sphere 901 has a grid-like distribution of several corresponding embedding grooves 9011. Molten metal is poured into the inlet end of the insulated feed cylinder 1. As the amount of molten metal increases, the high-temperature resistant ceramic piston 6, under its own weight, descends to the upper part of the insulated feed cylinder 1 where the ceramic spheres 901 enter. Slag and oxides in the molten metal float to the top of the molten metal, forming a slag layer. The plug body 5 is moved outwards to allow the feed hole to... 4. When the flow is open, the molten metal continues to be poured into the insulated material guide cylinder 1. The molten metal at the bottom of the slag layer flows through the material guide hole 4 and is filtered by the foam ceramic filter 2 before being poured into the casting port 301 of the iron sand box 3. When the material in the insulated material guide cylinder 1 decreases, the elastic element 8 lifts the high-temperature resistant ceramic column 7 and the high-temperature resistant ceramic piston 6. The molten metal on the upper side of the high-temperature resistant ceramic piston 6 enters the material guide hole 4, and the slag layer above the molten metal covers and fixes the surface of the ceramic sphere 901.

[0029] The present invention includes an insulated material guide cylinder 1 installed at the pouring port 301 of the iron sand box 3. A foam ceramic filter 2 is installed at the discharge end of the insulated material guide cylinder 1, and a material guide hole 4 is provided on its side wall. A plug 5 for controlling the opening and closing of the material guide hole 4 is movably installed on the insulated material guide cylinder 1. Then, a high-temperature resistant ceramic piston 6 is added inside the insulated material guide cylinder 1, and a high-temperature resistant ceramic column 7 and an elastic element 8 are used to buffer the high-temperature resistant ceramic piston 6. Finally, a scum layer collection component 9 is added, which includes a ceramic sphere 901 set on the high-temperature resistant ceramic column 7. The surface of the ceramic sphere 901 is evenly distributed with a number of corresponding embedded grooves 9011 in a grid pattern. During the casting process, molten metal is poured into the inlet of the insulated feed cylinder 1. As the amount of molten metal increases, the high-temperature resistant ceramic piston 6, under its own weight, descends to the ceramic sphere 901 and enters the upper part of the insulated feed cylinder 1. This causes slag and oxide inclusions in the molten metal to float to the top of the molten metal, forming a slag layer. Then, the plug 5 is moved outward to open the feed hole 4. As the molten metal continues to be poured in, the molten metal at the bottom of the slag layer flows through the feed hole 4 and is filtered by the foam ceramic filter 2 before being poured into the casting port 301 of the iron mold sand box 3. This effectively achieves the desired casting quality. The removal of slag and oxide inclusions in the material is crucial. Most importantly, during the pouring of molten metal, when human error causes a decrease in the material within the insulating guide cylinder 1, or when the material in the insulating guide cylinder 1 decreases near the end of the pouring process, the elastic element 8 lifts the high-temperature ceramic column 7 and the high-temperature ceramic piston 6. This allows the molten metal above the high-temperature ceramic piston 6 to enter the guide hole 4, thus maintaining the purity of the poured molten metal. The slag layer on top of the molten metal is then fixed to the surface of the ceramic sphere 901. This effectively improves the filtration rate of slag and oxide inclusions in the casting material without affecting the normal pouring process, thereby significantly improving the casting quality of the robot components.

[0030] The high-temperature resistant ceramic column 7 is integrally formed with an annular mounting flange 902 for supporting the ceramic sphere 901. The ceramic sphere 901 is hollow, and its bottom end is sealed to the annular mounting flange 902. The hollow area of ​​the ceramic sphere 901 is filled with numerous corresponding spherical ceramic damping particles 903 for vibration reduction. The frictional energy dissipation between the spherical ceramic damping particles 903 can reduce the degree of tumbling of the molten metal during the pouring process to a certain extent, thereby helping to improve the flotation rate of slag and oxide inclusions in the molten metal and the stability of the formed slag layer, thus effectively helping to improve the filtration rate of slag and oxide inclusions contained in the casting material.

[0031] The top of the ceramic sphere 901 is provided with a corresponding filling hole 10, and the spherical ceramic damping particles 903 are filled into the hollow area of ​​the ceramic sphere 901 through the filling hole 10.

[0032] The high-temperature resistant ceramic column 7 is fitted with a counterweight cover plate 11 for sealing the filling hole 10 of the ceramic sphere 901.

[0033] The heat-insulating guide cylinder 1 is provided with a limiting flange 12 located between the inlet and outlet of the guide hole 4. When the high-temperature resistant ceramic piston 6 descends under the weight and comes into contact with the limiting flange 12, the counterweight cover plate 11 is located on the upper side of the inlet of the heat-insulating guide cylinder 1.

[0034] The ceramic sphere 901 of the present invention has a corresponding filling hole 10 at its top. Spherical ceramic damping particles 903 are filled into the hollow area of ​​the ceramic sphere 901 through the filling hole 10 to ensure that the spherical ceramic damping particles 903 can be filled smoothly. At the same time, the filling hole 10 of the ceramic sphere 901 is closed by the counterweight cover plate 11, and the downward stroke of the high-temperature resistant ceramic piston 6 is limited by the limiting flange 12 to ensure that the counterweight cover plate 11 is always located above the feed port of the heat-insulating guide cylinder 1, thereby preventing the molten metal from entering the hollow part of the ceramic sphere 901 during pouring, so as to prevent the friction energy dissipation between the spherical ceramic damping particles 903 from being affected, and thus ensuring the practical effect of the present invention.

[0035] The foam ceramic filter 2 is circular in shape, and its diameter is smaller than the inner diameter of the limiting protrusion 12 to ensure the convenience of replacing the foam ceramic filter 2, thereby effectively ensuring the practical effect of the present invention.

[0036] The bottom of the outer wall of the insulating material guide cylinder 1 is provided with a corresponding mating flange 13, which is detachably locked to the iron shell of the iron sand box 3 by bolt locking. The discharge end of the insulating material guide cylinder 1 extends to the bottom side of the mating flange 13 and is inserted into the pouring port 301 of the iron sand box 3. This effectively achieves the detachable installation of the insulating material guide cylinder 1 while maintaining smooth pouring connection, thereby effectively realizing the reusability of the present invention.
