Description

Technical Field

[0001] The present invention relates to the field of casting technology, and particularly to an automatic pouring and mold clamping device. Background Art

[0002] During the casting pouring process, performing a mold clamping operation on the sand mold is a necessary step to ensure production safety and the quality of the casting. When the molten metal is poured, if the seam of the sand mold during mold closing is not well sealed, the molten metal is very likely to overflow from here. This will not only cause the sand mold to be scrapped due to running fire, resulting in waste of raw materials, but may also lead to serious safety accidents and endanger the lives of on-site personnel.

[0003] Currently, the mold clamping operation mainly relies on manual operation. First, a heavy mold clamping iron is lifted by a crane to a designated position, and then workers manually use a screw to position and fix the mold clamping iron. However, this traditional operation method has many drawbacks and is not suitable for an automated pouring production line. On the one hand, the coordinated operation of crane lifting and manual screw positioning is extremely cumbersome, resulting in extremely low on-site operation efficiency and seriously restricting the overall production progress. On the other hand, workers need to frequently carry, install the mold clamping iron and operate the screw, consuming a huge amount of physical strength and having a very high working intensity. In such a working environment for a long time, workers are extremely prone to fatigue, which in turn increases the risk of human error. Summary of the Invention

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used herein in the description of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0029] An embodiment of the present invention discloses an automatic pouring and pressing box device, and this automatic pouring and pressing box device is disposed at the pouring station of a casting production line. As Figure 1As shown in the figure, the disclosed automatic pouring and flasking device includes a main frame 100, a conveying mechanism, and a flasking mechanism. The conveying mechanism is installed inside the main frame 100 and is used to convey the sand mold 500 to be poured from the previous process station to the pouring station. After the pouring is completed, the sand mold 500 is conveyed from the pouring station to the next process station. Two groups of flasking mechanisms are respectively installed at the tops of the two side frames of the main frame 100. These two groups of flasking mechanisms are symmetrically arranged and cooperate with each other to flask the sand mold 500 conveyed to the pouring station, effectively preventing the mold from lifting and running fire during automatic pouring.

[0030] In the disclosed embodiment of the present invention, the flasking mechanism may include a support platform 210, a mounting seat 240, a first driving member 220, and a robotic arm. The support platform 210 is fixedly arranged at the top of the side frame of the main frame 100 and is used to install other components of the flasking mechanism. Among them, the first driving member 220 is installed on the lower surface of the support platform 210, and a mounting seat 240 for installing the robotic arm is fixedly arranged on the top surface of the support platform 210. Specifically, the robotic arm is provided with a pressing arm end 231 and a driving end 232. An installation part is arranged near the driving end 232 between the pressing arm end 231 and the driving end 232. The installation part is rotatably connected to the mounting seat 240 through a rotating shaft. The pressing arm end 231 is located above the support platform 210, and the driving end 232 is located below the support platform 210 and is connected to the output end of the first driving member 220. The first driving member 220 drives the driving end 232 to rotate, further driving the pressing arm end 231 to rotate for flasking operations.

[0031] It should be noted that the structures of the two groups of flasking mechanisms may be the same. The two groups of flasking mechanisms are symmetrically arranged, and the pressing arm ends 231 of the two robotic arms are arranged oppositely facing the inside of the main frame 100 and cooperate with each other to flask the sand mold 500 conveyed to the pouring station.

[0032] Furthermore, the first driving member 220 may be a hydraulic cylinder, and a connecting rod is arranged at its output end. The end of the connecting rod away from the hydraulic cylinder is hinged to the driving end 232 of the robotic arm. On the one hand, the hydraulic cylinder can drive the robotic arm to rotate around the rotating shaft for flasking operations, and by controlling the driving force, action time, etc. of the hydraulic cylinder, the flasking force and flasking time of the pressing arm end 231 can be automatically and precisely controlled, avoiding overpressure and underpressure from affecting the deformation of the sand mold and insufficient flasking. On the other hand, during the process of the pressing arm end 231 lifting when the pressure is released, since the hydraulic cylinder has a pulling force limiting effect on the driving end 232, it can effectively prevent the pressing arm end 231 from rotating too fast or rotating too much and dropping to damage the sand mold, wear out components such as the rotating shaft, etc.

[0033] In the disclosed embodiments of the present invention, the conveying mechanism may include a conveying bracket 310, a conveying roller path 320, a chain assembly 340, and a conveying motor 330. Two conveying brackets 310 are fixedly arranged on the bottom frame of the main frame 100, and the conveying roller path 320 is installed on the opposite sides of the upper parts of the two conveying brackets 310. A conveying motor 330 is installed in the middle of one of the conveying brackets 310, and a chain assembly 340 is also installed on the outer side of this conveying bracket 310 for the transmission between the conveying motor 330 and the conveying pipe path 320.

[0034] Specifically, the chain assembly 340 may include a chain, a first sprocket, and a second sprocket. The first sprocket is connected to the output shaft of the conveying motor 330, the second sprocket is connected to the conveying roller path 320, and the chain is wound around the first sprocket and the second sprocket. The conveying motor 330 drives the first sprocket to rotate forward, and the chain drives the second sprocket to rotate, further driving the conveying roller path 320 to rotate forward to convey the sand mold 500 placed on the conveying roller path 320 to the pouring station or the pouring platform docked with the conveying roller path 320; the conveying motor 330 drives the first sprocket to rotate backward, and the chain drives the second sprocket to rotate, further driving the conveying roller path 320 to rotate backward to convey the sand mold 500 on the pouring station or the pouring platform away.

[0035] Further, the sand mold 500 may be placed in the tray 400 and conveyed together with the tray 400 by the conveying mechanism, and is compacted by the box pressing mechanism in the tray 400 for pouring.

[0036] Furthermore, the automatic pouring and box pressing device disclosed in the embodiments of the present invention may further include a PLC controller and a sensor. Among them, the PLC controller is connected to the first driving member 220 and / or the conveying motor 330 for controlling the first driving member 220 and / or the conveying motor 330; the sensor may be arranged on the main frame 100 and connected to the PLC controller for detecting whether the sand mold 500 is conveyed in place and feeding back to the PLC controller.

[0037] When pouring operation is required, the PLC controller controls the first driving member 220 to drive the robotic arm to rotate and raise the pressing arm end 231 to the highest position. The PLC controller controls the conveying motor 330 to drive the conveying roller path 320 to rotate forward, and conveys the sand mold 500 placed on the conveying roller path 320 to the pouring station or the pouring platform. When the sensor detects that the sand mold 500 is conveyed in place, it feeds the in-place signal back to the PLC controller, and the PLC controller controls the conveying motor 330 to stop running. The PLC controller controls the first driving member 220 to drive the robotic arm to rotate according to preset parameters such as pressing box strength and time, lowers the pressing arm end 231 to a suitable position, and performs the pressing box operation with a suitable pressure and time. After pouring is completed, the PLC controller controls the first driving member 220 to drive the robotic arm to rotate, raises the pressing arm end 231 to remove the pressing box force. The PLC controller controls the conveying motor 330 to drive the conveying roller path 320 to rotate in reverse, and conveys the sand mold 500 on the pouring station or the pouring platform away.

[0038] In this embodiment, the PLC controller can be the controller of the automatic pouring system. Of course, the PLC controller can also be connected to the management system of the casting production line and feed back the pressing box and conveying operation data to the management system.

[0039] The above-described embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
