[0043] The present invention is further described below in conjunction with the accompanying drawings and embodiments. It is hereby stated that the present invention is explained by these illustrative embodiments, but is not intended to be a limitation of the present invention.

[0044] See also Figure 1-Figure 6 The quantitative multi-station multi-flow channel automatic pouring machine of the present invention comprises a multi-flow channel switching pouring module 1, a large ladle transport dumping module 2 and a sand box transport module 3. The sand box transport module 3 can be provided with a matrix ( Figure 1 The sand boxes are distributed in three rows and three columns. Figure 6 Taking the orientation shown as an example, the left and right directions are the rows of the matrix, and the up and down directions are the columns of the matrix. The multi-runner switching pouring module 1 is installed on the large ladle transport and dumping module 2 and is located above the sand box provided in the sand box conveying module 3. The multi-runner switching pouring module 1 can receive the molten metal dumped by the large ladle transport and dumping module 2 and guide the molten metal to the molten metal inlet of the sand box;

[0045] The multi-runner switching pouring module 1 includes a front end bracket 101, a front end pouring funnel 102, a runner switching mechanism 103 and a runner moving drive mechanism 104. The front end bracket 101 is fixed on the large ladle transport and dumping module 2. The front end pouring funnel 102 is fixed on the front end bracket 101 and is used to receive the molten metal dumped by the ladle in the large ladle transport and dumping module 2. The runner switching mechanism 103 is installed on the front end bracket 101 and is arranged below the front end pouring funnel 102. The runner moving drive mechanism 104 is installed on the front end bracket 101 and connected to the runner switching mechanism 103. The runner switching mechanism 103 includes a plurality of inclined runners of different lengths arranged side by side, and the runners of different lengths respectively correspond to different rows of sand boxes distributed in a matrix form on the sand box conveying module 3, and the higher end of each runner can receive the molten metal flowing out of the outlet of the front pouring funnel 102, and a runner gate 1030203 is provided at the bottom of the lower end of the runner; the runner moving drive mechanism 104 can drive the runner switching mechanism 103 to move, so that the lower end of each runner can introduce the molten metal into the sand box corresponding to the runner through the runner gate 1030203.

[0046] Combination Figure 6When the quantitative multi-station multi-runner automatic pouring machine of the present invention is working, the relative position between the sand box conveying module 3 and the large ladle conveying and dumping module 2 is adjusted so that the runner gate 1030203 of one of the runners on the multi-runner switching pouring module 1 is vertically aligned with the molten metal inlet of the sand box, and then the metal amount of a sand box is poured into the front pouring funnel 102 through the large ladle conveying and dumping module 2, and then the large ladle conveying and dumping module 2 is reset. After the molten metal in the runner has flowed out, the runner moving driving mechanism 104 is used to drive the runner switching machine The mechanism 103 moves to make another runner located below the outlet of the front pouring funnel 102 ready to receive the molten metal, and then the amount of metal for casting a sand box is poured into the front pouring funnel 102 through the large ladle transport and dumping module 2, and then the large ladle transport and dumping module 2 is reset. After the molten metal in the runner has flowed out, the runner moving drive mechanism 104 drives the runner switching mechanism 103 to move, and switches to another runner for casting, until all runners are cast (that is, all the sand boxes that can be cast on the sand box transport module 3 are cast, and the casting is completed). Figure 6 For example, there are a total of three rows in the sand box conveying module 3. The relative position between the sand box conveying module 3 and the large ladle transport and dumping module 2 is adjusted once, and at most one sand box in each of the three rows can be cast. When the casting of the three sand boxes that can be cast in the three rows is completed, it is considered that the relative position between the sand box conveying module 3 and the large ladle transport and dumping module 2 is adjusted once, and the casting of all the sand boxes that can be cast is completed). The relative position between the sand box conveying module 3 and the large ladle transport and dumping module 2 is readjusted, and then the next round of casting is carried out; since the flow channel switching mechanism 103 has a plurality of inclined flow channels of different lengths arranged side by side, each time the relative position between the sand box conveying module 3 and the large ladle transport and dumping module 2 is adjusted once, multiple sand boxes can be cast, which greatly improves the casting efficiency.

The guide rail 10301 is installed on the front bracket 101. The flow channel support body 10305 is adapted to be connected with the guide rail 10301. The flow channel support body 10305 can move along the guide rail 10301. The moving direction of the flow channel support body 10305 on the guide rail 10301 is consistent with the row direction of the sand box distributed in the form of a matrix on the sand box conveying module 3 (referring to the direction where the matrix row is located, with Figure 6 For example, it refers to the left and right direction); the flow channels are fixed on the flow channel support body 10305, and the flow channels and the sand box conveying module 3 are distributed in the form of a matrix in the column direction of the sand box (referring to the direction in which the matrix column is located, with Figure 6For example, it refers to the up and down direction), the runner moving drive mechanism 104 is connected to the runner support body 10305, and the runner moving drive mechanism 104 can drive the runner support body 10305 to move back and forth on the guide rail 10301. Through the reciprocating movement of the runner support body 10305, runners of different lengths are realized to receive the molten metal at the outlet of the front pouring funnel 102.

[0048] In the present invention, a limiting groove for limiting the flow channel can be opened on the flow channel support body 10305, and the higher end of the flow channel is fixed in the limiting groove. The stability of the flow channel installation position can be ensured by the limiting groove; all flow channels include channel steels of preset lengths, and the two ends of the channel steels are respectively provided with a flow channel front baffle 1030201 and a flow channel rear baffle 1030202, wherein the flow channel front baffle 1030201 and the flow channel rear baffle 1030202 are respectively located at the lower end and the higher end of the channel steel, and the flow channel rear baffle 1030202 is fixedly installed in the limiting groove.

The flow channel support body 10305 can reciprocate on the guide rail 10301 through the forward and reverse rotation of the first motor 10401;

[0051] The first chain 10403 is located below the runner support body 10305 and the front end pouring funnel 102 and is on the side of the front end pouring funnel 102 away from the runner, so that the runner support body 10305 can be used for shielding to avoid damage caused by long-term heat radiation and to avoid the molten metal splashed from the outlet of the front end pouring funnel 102 from adhering to the first chain 10403 and causing the first chain 10403 to fail to work normally.

At this time, the large ladle transport module 2 and the multi-runner switching casting module 1 stop at a suitable casting position. At this time, the servo motor 20501 in the rotating drive mechanism 205 transmits power to the drive shaft 20504 through the right-angle reducer 20502 and the connecting flange 20508. Two driving sprockets 20505 are installed on both sides of the driving shaft 20504. The driving sprocket 20505 drives the driven sprocket 20506 to rotate through the chain 20507, thereby driving the connecting flange 20403 in the ladle installation module 204 to rotate, and realize the tipping movement of the large ladle 20406. When the weight sensing module 202 detects that the upper weight change meets the threshold, the controller module 206 controls the rotating tipping mechanism 205 to repeat the above steps to return the large ladle 20406 to the normal position.

Both ends of the channel switching mechanism 103 are connected to a channel movement driving mechanism 104 for driving the channel switching mechanism to move; the channel switching mechanism 103 includes a guide rail 10301, a proximal channel 10302, a mid-position channel 10303, and a distal channel 10304, the proximal channel 10302, the mid-position channel 10303, and the distal channel 103 04 are all installed on the runner support body 10305, and the pulley 10306 is installed on the runner support body 10305, so that the runner support body 10305 can slide on the guide rail 10301; the runner movement drive mechanism 104 drives the runner support body 10305 to move left and right on the guide rail 10301, so that the middle runner 10303, the proximal runner 10302, and the distal runner 10304 located on the runner support body 10305 are located directly below the front end pouring funnel 102 in sequence, so as to guide the molten iron flowing out of the front end pouring funnel 102 to flow to the middle, proximal, and distal sand boxes in sequence. The middle runner 10303, the proximal runner 10302, and the distal runner 10304 are welded by a certain length of channel steel, the runner front baffle 1030201, the runner rear baffle 1030202, and the runner gate 1030203. The runner rear baffle 1030202 is buckled at the bottom of the runner support 10305. The main body of the runner is channel steel, and the runner rear baffle 1030202 is bent and processed by ordinary steel plate. The contact surface between the runner and the molten iron is coated with fireproof mud; the main body of the runner support 10305 is channel steel, and a limit groove is cut on the main channel steel to limit the left and right position of the runner, and support plates are welded at the four corners of the bottom of the channel steel to install the pulley 10306. The motor in the flow channel moving drive mechanism 104 drives the chain transmission, and the chain is welded on the flow channel support body 10305, thereby driving the flow channel switching mechanism 103 to move, so that the flow channels of different lengths are sequentially located directly below the front pouring funnel 102, thereby realizing the casting of the middle, near and far positions. Figure 7 , Figure 9-11The large ladle transport dumping module 2 relies on the rail car 20101 to move linearly along the second track 20102. The rail car 20101 chassis is equipped with a servo motor 20103, which is driven by a chain 20105. The rail car 20101 is equipped with a laser sensor 20104. When the distance measured by the laser sensor 20104 is the set value, it indicates that the distance between the rail car 20101 and the casting box transport module 2 has reached a suitable casting distance. At this time, the controller module 206 controls the servo motor 20103 to stop moving, realizing the closed-loop control of the casting position of the entire large ladle transport module 2 and the multi-flow channel switching casting module 1, ensuring the accurate positioning of the casting point. The rail car module 201, the weight sensing module 202, and the adjustable center support seat 203 are installed from bottom to top, and the ladle installation module 204, the rotation drive mechanism 205 and the controller module 206 are all arranged above the adjustable center support seat 203. The weight sensing module 202 includes a plurality of weight sensors 20201, which are evenly mounted on the railcar 20101 to sense the change of the upper weight in real time. When the railcar 20101 stops at a suitable position, the controller module 206 controls the servo motor 20501 in the rotating drive mechanism 205 to transmit power to the drive shaft 20504 via the right-angle reducer 20502 and the connecting flange 20508. Two driving sprockets 20505 are mounted on both sides of the drive shaft 20504. The driving sprocket 20505 drives the driven sprocket 20506 to rotate through the chain 20507, thereby driving the connecting flange 20403 in the ladle installation module 204 to rotate, thereby realizing the tipping movement of the large ladle 20406. When the weight sensing module 202 detects that the change of the upper weight meets the threshold, the controller module 206 controls the rotating tipping mechanism 205 to repeat the above steps to return the large ladle 20406 to the normal position. The entire control process is a closed-loop control based on weight changes, which can control the amount of molten iron poured out to prevent insufficient molten iron from affecting casting molding and excessive molten iron from causing overflow. Figure 5 The sand box transport railcar 301 in the sand box transport module 3 is equipped with latches and traction ropes at both ends, and the ropes are connected to the winch 303, and the sand box transport railcar is dragged by the winch to move; the sand box positioning frame 302 is installed on the sand box transport railcar 301, and is used to position the sand box to be poured. When all the sand boxes on the sand box transport railcar 301 are poured, the winch 303 drags the sand box transport railcar to the unloading place of the poured sand boxes, and after placing the new sand boxes to be poured, the winch 303 at the other end drags the sand box transport railcar to the starting point of the pouring line, which ensures that the molten iron has enough solidification time during the pouring process and reduces the time for changing the mold.

[0076] The working process of the quantitative multi-station multi-runner automatic pouring machine in this embodiment includes the following steps:

[0077] Step 1: When the pouring machine starts pouring, the rail car module 201 drives the large ladle transport dumping module 2 and the multi-channel switching pouring module 1 to move in a straight line. When the distance measured by the laser sensor 20104 is the set value, the sand box on the sand box conveying module 2 reaches the specified position, and the rail car module 201 stops moving and starts the next action.

[0078] Step 2: When the large ladle transport dumping module 2 moves to a suitable casting position, the controller module 206 controls the rotation drive mechanism 205 to move, so that the large ladle 20406 rotates and dumps the molten iron. The molten iron flows into the front casting funnel 102, passes through the middle flow channel 10303 in the multi-flow channel switching casting module 1, and finally enters the middle sand box. The weight sensing module 202 monitors the upper weight change in real time. When the weight change reaches the specified threshold, the controller module 206 sends a command to the servo motor 20501 in the rotation drive mechanism 205, controls the servo motor 20501 to rotate in the opposite direction, and level the large ladle 20406 to stop dumping the molten iron, complete the casting of the middle sand box of this station, and start the next action.

[0079] Step 3: After the casting of the intermediate sand box is completed, the controller module 206 controls the runner moving drive mechanism 104 to drive the runner support body 10305 to move a fixed distance on the guide rail 10301, so that the proximal runner 10302 is below the front casting funnel 102. At this time, the controller module 206 will repeat the action in step 2 to complete the casting of the proximal sand box of this station. Next, the controller module 206 controls the runner moving drive mechanism 104 to drive the runner support body 10305 to move a fixed distance on the guide rail 10301, so that the distal runner 10304 is below the front casting funnel 102, completing the casting of the three rows of sand boxes of this station, and starting the next action.

[0080] Step 4: After the casting of three rows of sand boxes at a certain station is completed, step 1 is repeated, and the large ladle transport dumping module 2 and the multi-flow channel switching casting module 1 are driven by the rail car module 201 to move to the next station, and then steps 2 and 3 are repeated until the casting of all sand boxes on the entire sand box transport module 3 is completed. At this time, the winch 303 drags the sand box transport rail car to the unloading place of the sand box after the casting is completed, and after placing the new sand box to be cast, the winch 303 at the other end drags the sand box transport rail car to the starting position of the casting line to carry out the next round of casting.

[0081] It can be seen from the above scheme that the quantitative multi-station multi-runner automatic pouring machine of the present invention can realize the accurate movement of the runner pouring port to the pouring position by using the large ladle transport dumping module and the multi-runner switching module, which is suitable for the current large-scale small casting casting in which the molds are neatly arranged in rows and columns; the multi-runner switching module is installed on the large ladle transport dumping module, so the multi-runner switching module can follow the large ladle transport dumping module to move to the pouring position, and the runner moving drive mechanism can be used to realize that the multiple runners on the runner switching mechanism are moved to the bottom of the front pouring funnel in sequence, so as to receive the molten iron dumped by the large ladle transport dumping module; three runners of different lengths will guide the molten iron to the three rows of sand boxes in the same column respectively, and complete the pouring of the middle sand box, the near sand box, and the far sand box. The weight sensing module on the large ladle transport dumping module is used to rotate the drive mechanism and the controller module to realize the quantitative dumping of molten iron. By utilizing the sand box transport module, the batch transfer of the sand boxes after pouring can be realized, and at the same time, the ladle on the large ladle transport dumping module can be replaced to achieve a unified production rhythm. In summary, the present invention can pour multiple molds at one time, and can also ensure that each mold poured is poured with a sufficient amount of molten iron, and ensure the solidification time of the poured molten iron, and ensure the pouring quality, so the present invention realizes a fast, efficient and reliable pouring process.

[0082] The flow channel support body of the present invention is directly processed from channel steel, and the main bodies of the proximal, middle and distal flow channels are also channel steels, which are all obtained by cutting and welding standardized steel materials. The parts processing is simple and the processing and manufacturing cost is low. Most of the chains of the chain transmission structure of the flow channel moving drive mechanism of the present invention are located below the flow channel support body, which well shields the high temperature of pouring and pouring molten iron. Therefore, the flow channel moving drive mechanism of the present invention has better lubrication conditions and prolongs the service life of the flow channel moving drive mechanism.

[0083] The present invention uses weight detection to perform closed-loop control on the rotary drive mechanism, and monitors the weight of the upper part in real time through the weight sensing module. When the weight change reaches the amount of molten iron that needs to be poured out, the control module controls the servo motor to start, return the ladle position to the normal position, and stop pouring. Compared with the traditional timed pouring, the amount of molten iron poured out can be accurately controlled to prevent the insufficient amount of molten iron from affecting the molding of castings and the excessive amount of molten iron from causing overflow. At the same time, the weight sensing module is composed of a plurality of evenly arranged weight sensors to avoid the situation where the weight above exceeds the measurement range of a single weight measuring instrument. In conjunction with the self-aligning support seat above, the stability of the environment and the accuracy of the measurement can be ensured during weight measurement.

[0084] The present invention uses a laser sensor to detect the distance between the rail car and the sandbox transport module to achieve closed-loop control of the rail car module servo motor. When the laser sensor detects that the distance between the current rail car and the sandbox transport module reaches the set position, the control module controls the servo motor at the bottom of the rail car to stop moving and prepare for casting at the current position. The laser sensor module is wrapped with a thermal insulation layer to ensure that it can still work normally in a high temperature environment and ensure the accuracy of the casting position positioning.

[0085] In summary, the present invention aims at the problems existing in the existing pouring machines, and provides a multi-flow channel switching pouring module that automatically adjusts the flow direction of molten iron, a large ladle transport and dumping module that automatically performs movement and dumping actions, and a sand box transport module that can transport the cast molds to the unloading area in batches. The multi-flow channel switching pouring module of the present invention is fixed to the large ladle transport and dumping module by welding, and cooperates with the four weight sensing modules located on the large ladle transport and dumping module. By rotating the drive mechanism and the controller module, the ladle is driven to dump, and the molten iron can be dumped quantitatively, which greatly guarantees the pouring quality. The flow channel support body and flow channel of the multi-flow channel switching mechanism of the present invention are simple to manufacture, easy to coat with high temperature resistant materials, and easy to manufacture. The flow channel switching can be realized through the flow channel moving drive mechanism, and the poured molten iron is drained to the pouring ports of the sand boxes in the same column but different rows, thereby realizing the pouring of the sand boxes in the same column and different rows at a fixed station. Most of the chains of the runner moving drive mechanism do not reach the bottom of the runner support body, which avoids the damage of the transmission mechanism to the splashing of molten iron during the pouring process, isolates most of the heat, and ensures the working environment of the drive mechanism. The sand box transport module is fixed in position during the pouring process, and the station adjustment is realized by the large ladle transport dumping module. The rail car module in the large ladle transport dumping module moves, and cooperates with the laser sensor to determine whether it reaches the next pouring station. The rail car module is directly driven by the servo motor to ensure that the positioning control accuracy meets the requirements. During the entire pouring process, the ladle moves and the sand box is fixed, which ensures the stability and solidification time of the molten iron solidification in the sand box after pouring, effectively avoids the casting defects such as pores and cold shuts in the casting, and avoids the occurrence of casting defects in the automated sand casting process. The sand box transport module is driven by a winch to move the sand box transport rail car at the starting point and the end point, realizing the transportation of the finished casting mold to the unloading area and the transportation of the loaded uncast sand box to the pouring area, improving the efficiency and automation of the pouring production.
