Description

Technical Field

[0001] This utility model relates to the field of automatic sand suction technology for core making, specifically an automatic sand suction device for core making. Background Technology

[0002] Core making is the process of shaping sand into a core that conforms to the shape of a core box. It is divided into two types: manual core making and machine core making. Machine core making is more commonly used in mass production. Manual core making includes: clay sand core making, oil sand core making, resin sand core making, resin self-hardening sand core making, and water glass self-hardening sand core making, etc. Machine core making includes: hot core box method, warm core box method, resin-coated sand method, and cold core box method.

[0003] The existing automatic sand suction device for core making requires operators to carry the bagged fine sand to the feeding port of the core making equipment or load the bagged fine sand onto the lifting equipment and then pour it into the equipment each time fine sand is added. This method is time-consuming and labor-intensive, and is relatively inconvenient to use. In addition, the existing automatic sand suction device for core making is not easy to control the discharge speed, which leads to material waste and poor practicality. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example

[0023] Please see Figures 1 to 3 This utility model provides a technical solution: an automatic sand suction device for core making, including a base 1, a sand storage box 2 fixedly installed on the top of the base 1, a connecting pipe 3 fixedly installed on the top of the sand storage box 2, a filter screen 301 fixedly installed at one end of the connecting pipe 3, an air pump 4 fixedly installed on the top of the sand storage box 2, an air extraction pipe 5 fixedly installed on one side of the air pump 4, one end of the air extraction pipe 5 fixedly installed at one end of the connecting pipe 3, a feed pipe 6 fixedly installed on one side of the sand storage box 2, a control valve 7 fixedly installed on the outside of the feed pipe 6, and a branch pipe 8 fixedly installed on one side of the bottom of the feed pipe 6. The branch pipe 8 has an internal telescopic groove 9, and a telescopic sand suction pipe 10 is slidably connected inside the telescopic groove 9. A support 11 is fixedly installed on one side of the branch pipe 8, and a lead screw 12 is rotatably connected inside the support 11. A servo motor 13 is fixedly installed on one side of the branch pipe 8, and the output end of the servo motor 13 is fixedly installed on one end of the lead screw 12. A lifting seat 14 is drivenly connected to the outside of the lead screw 12, and one end of the lifting seat 14 is slidably connected to the outside of the branch pipe 8. A lifting frame 15 is fixedly installed on one end of the lifting seat 14, and one end of the lifting frame 15 is fixedly installed on one side of the telescopic sand suction pipe 10.

[0024] Specifically, the servo motor 13 is started, and the output end of the servo motor 13 drives the lead screw 12 to rotate inside the support 11. The lead screw 12 drives the lifting seat 14 to move, causing the lifting seat 14 to move downward outside the support pipe 8. The lifting seat 14 drives the lifting frame 15 to move downward, and the lifting frame 15 drives the telescopic sand suction pipe 10 to move, causing the outer side of the telescopic sand suction pipe 10 to move downward inside the telescopic groove 9 so that one end of the telescopic sand suction pipe 10 can be inserted into the sand suction. When sand suction is needed, the air pump 4 is started. The air pump 4 will extract the gas inside the sand storage box 2 through the air suction pipe 5 and the connecting pipe 3, and create a vacuum inside the sand storage box 2. At this time, the control valve 7 is opened. Since the fine sand has a mesh size of 140 and is very light, the gas pressure is used to suck the fine sand from the telescopic sand suction pipe 10 into the feed pipe 6. The fine sand inside the feed pipe 6 will flow into the sand storage box 2.

[0025] Please refer to Figure 3 to Figure 4 The bottom of the sand storage box 2 is provided with a discharge hole 16, and a sliding baffle 17 is slidably connected inside the discharge hole 16. A discharge pipe 18 is fixedly installed at the bottom of the discharge hole 16.

[0026] Specifically, the sliding baffle 17 moves upward inside the discharge hole 16, causing fine sand to be discharged from one end of the discharge pipe 18.

[0027] Please refer to Figure 3 to Figure 4 A movable groove 19 is provided on one side of the sand storage box 2, and a movable seat 20 is slidably connected inside the movable groove 19.

[0028] Specifically, the movable seat 20 moves upward inside the movable groove 19, and one end of the movable seat 20 is slidably connected inside the movable groove 19.

[0029] Please refer to Figure 3 to Figure 4 An electric telescopic rod 21 is fixedly installed on one side of the sand storage box 2, and the extended end of the electric telescopic rod 21 is fixedly installed on the bottom side of the movable seat 20.

[0030] Specifically, when the electric telescopic rod 21 is opened, the extended end of the electric telescopic rod 21 will drive the movable seat 20 to move upward inside the movable groove 19.

[0031] Please refer to Figure 3 to Figure 4 A movable frame 22 is fixedly installed on the top of the movable seat 20, and the other end of the movable frame 22 is fixedly installed on the top of the sliding baffle 17.

[0032] Specifically, the movable seat 20 will drive the movable frame 22 to move upward, and the movable frame 22 will drive the sliding baffle 17 to move upward inside the discharge hole 16.

[0033] In use, first, the position of the telescopic sand suction pipe 10 needs to be adjusted, and then the servo motor 13 is started. The output end of the servo motor 13 will drive the lead screw 12 to rotate inside the support 11. The lead screw 12 will drive the lifting seat 14 to move, causing the lifting seat 14 to move downward outside the support pipe 8. The lifting seat 14 will drive the lifting frame 15 to move downward, and the lifting frame 15 will drive the telescopic sand suction pipe 10 to move, causing the outer side of the telescopic sand suction pipe 10 to move downward inside the telescopic groove 9, so that one end of the telescopic sand suction pipe 10 can be inserted into the sand suction chamber. When sand suction is needed, the air pump 4 is started. The air pump 4 will extract the gas inside the sand storage box 2 through the air suction pipe 5 and the connecting pipe 3, and make the sand storage box 2... A vacuum is formed inside. At this time, the control valve 7 is opened. Since the fine sand has a mesh size of 140 and is very light, the fine sand is sucked into the inside of the feed pipe 6 by the gas pressure. The fine sand inside the feed pipe 6 will flow into the inside of the sand storage box 2. When it is necessary to discharge sand, the electric telescopic rod 21 is opened. The extended end of the electric telescopic rod 21 will drive the moving seat 20 to move upward inside the moving groove 19. The moving seat 20 will drive the moving frame 22 to move upward. The moving frame 22 will drive the sliding baffle 17 to move upward inside the discharge hole 16, so that the fine sand is discharged from one end of the discharge pipe 18. When the sliding baffle 17 is completely disengaged from the discharge hole 16, the discharge speed is the fastest.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
