Technical Field
[0001] The invention belongs to the technical field of core shooting machine core making, and relates to an ultra-high-speed multi-station fully automatic cold core box core shooting machine and a core making method. Background Art
[0002] The core shooter is a device that uses compressed air to evenly shoot the molding sand into the sand box for pre-compaction, and then applies pressure for compaction. The existing core shooter has a core production efficiency of about 240 sand cores per hour, which is low in production efficiency. In addition, the working mode of the existing core shooter is mostly a process in which the sand shooting head moves to shoot sand into the core box, which is a relatively cumbersome process. After the core is made, the existing core shooter is mostly manually coring and manually stacking, which has low working efficiency. Summary of the invention
[0003] In order to make up for the deficiencies of the prior art, the present invention provides an ultra-high-speed multi-station fully automatic cold core box core shooting machine and a core making method. The core shooting machine of the present method is provided with multiple core box stations, and multiple core box molds are automatically circulated in the core shooting machine, thereby improving the production efficiency of the core shooting machine. The present invention is achieved through the following technical scheme: The present invention provides an ultra-high-speed multi-station fully automatic cold core box core shooting machine, including a preparation workbench, a sand shooting workbench, an air blowing workbench, a filtering workbench, and a mold opening and closing workbench connected to each other; a coring, handling, and coating manipulator, a coring, handling, and stacking manipulator, a coating dip coating machine, a sand core tray, and a tray conveying device.
[0004] A super-high-speed multi-station fully automatic cold core box core shooting machine core making method includes a core box mold installation process, a core making process, a robot core removal, transportation, coating and stacking process; the core making process includes a sand shooting process, an air blowing process, and a mold opening and core ejection process.
[0005] The installation steps of three sets of core box molds include: Execute the core box installation program. The first set of core box molds moves from station 0 of the preparation workbench to station 3.1 and station 3 of the sand shooting workbench, station 4 of the air blowing workbench, and then to station 1 of the mold opening and closing workbench, and then waits at station 1.1. The second set of core box molds enters the installation program, and moves from station 0 of the preparation workbench to station 3.1 and then to station 2 to wait; then the third set of core box molds enters the installation program, and moves from station 0 to station 3.1; at this time the installation program ends.
[0006] The steps of the core making process of three sets of core box mold cycles include: After the core box mold is installed, the core shooting machine presses the production button to enter the production operation program. The third set of core box molds rises from station 3.1 to station 3 for sand shooting, and moves to station 4 for air blowing after completing the sand shooting process. At this time, the empty sand shooting workbench at station 3 drops to station 3.1, and the second set of core box molds at station 2 has been waiting in place until it is detected that the core box mold at station 3.1 is empty, then it automatically moves to the sand shooting workbench at station 3.1, rises from station 3.1, tightens and puts in place, and directly presses the core box to complete the station installation of the core box mold at station 3, and performs the sand shooting process; the first set of core box molds at station 1.1 has also been waiting in place until it is detected that the mold at station 2 is empty, then it automatically moves to the transition workbench at station 2; after the third set of core box molds completes the air blowing process, it moves from station 4 to station 1, and the second set of molds moves when the sand shooting process is completed and station 4 is an empty mold. Enter station 4 for the air blowing process. At this time, the mold in station 3 is empty, and its sand shooting workbench automatically descends to station 3.1. The first set of molds located in station 2 detects that there is a sand shooting workbench in station 3.1 and the mold is empty, so it moves to station 3.1, automatically rises, tightens, and pushes the core box to carry out the sand shooting process after arriving at station 3; the third set of core box molds automatically descends to station 1.1 for mold closing and core returning after the mold opening and closing workbench in station 1 carries out the mold opening and core pushing process; the second set of core box molds moves to station 1 to continue the mold opening and core pushing process after completing the air blowing process; the first set of core box molds moves to station 4 to carry out the air blowing process after completing the sand shooting process; the third set of core boxes that have passed the core making process continue to be executed in subsequent cycles at station 1.1, and the second set of core box molds and the first set of core box molds are the same. The three sets of core box molds cycle up and down in turn to perform each core making process; the stagnation time of the equipment is reduced and the production efficiency is improved.
[0007] The beneficial effects of the present invention are: The present invention uses only one core shooting machine process to realize the simultaneous production of one to three sets of molds. Multiple sets of core box molds are cyclically subjected to sand shooting, air blowing and mold opening, thereby improving the utilization rate of the equipment and greatly improving the core making efficiency. The efficiency of producing sand cores using the equipment reaches 600 per hour.
[0008] The present invention adopts a robot to wait for taking away the sand core at the core opening and core pushing station after the core making is completed, and after grabbing the sand core, enters the subsequent coating process to coat the sand core, and another robot grabs the coated sand core to carry out the stacking process.
[0009] The present invention integrates material taking, core making, coating and stacking into one machine device, realizes ultra-high-speed production of sand cores, and realizes high-efficiency core making through the movement of the core box mold. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] The present invention will be further described below in conjunction with the accompanying drawings; Figure 1is a flow chart of the method of the present invention; Figure 2 It is a top view of the sand core stacking of the present invention. DETAILED DESCRIPTION
[0011] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.
[0012] The accompanying drawings show a specific embodiment of an ultra-high-speed multi-station fully automatic cold core box core shooting machine and a core making method of the present invention.
[0013] An ultra-high-speed multi-station fully automatic cold core box core shooting machine includes a preparation workbench, a sand shooting workbench, an air blowing workbench, a filtering workbench, a mold opening and closing workbench connected to each other; a coring, handling, and coating manipulator, a coring, handling, and stacking manipulator, a coating dip coater, a sand core tray, and tray conveying equipment.
[0014] A super-high-speed multi-station fully automatic cold core box core shooting machine core making method includes a core box mold installation process, a core making process, a robot core removal, transportation, coating and stacking process; the core making process includes a sand shooting process, an air blowing process, and a mold opening and core ejection process.
[0015] When installing two sets of core box molds, the core box molds are installed on the preparation workbench. The first set of core box molds moves from station 0 of the preparation workbench to station 3.1 of the sand shooting workbench and station 3, and station 4 of the air blowing workbench, and then to station 1 of the mold opening and closing workbench, and then waits at station 1.1. At this time, the second set of core box molds enters the installation procedure, from station 0 of the preparation workbench to station 3.1, and the installation procedure ends.
[0016] The steps of the core making process of two sets of core box mold cycles include: Turn on the automatic operation button of the equipment; the second set of core box molds moves to station 3.1 after mechanical limit positioning, and the second set of core box molds enters the working state; the second set of core box molds rises from station 3.1 to station 3 to enter the sand shooting program, and the first set of core box molds waiting at station 1.1 is judged that the mold at station 2 is empty and moves to the transition workbench at station 2; when the second set of molds completes the sand shooting process, it will automatically enter the blowing workbench station 4, and at this time, the sand shooting workbench station 3 is empty and automatically descends to station 3.1 to wait; the first set of core box molds at station 2 monitors If there is a vacant position in station 3.1, it will be moved to the sand-shooting workbench of station 3.1; then the first set of core box molds will be raised and tightened, and after reaching the specific position of the sand-shooting process, they will be tightened and enter station 3 for the sand-shooting process; when the second set of core box molds is moved from the blowing workbench to the mold opening and closing workbench of station 1, the first set of core box molds will move to the blowing workbench of station 4 for the blowing process after completing the sand-shooting process at station 3; the second set of core box molds will automatically descend, close the mold, and return to station 1.1 after completing the mold opening and coring processes at station 1, and the two sets of core box molds will cycle through the core-making process in turn.
[0017] When the first set of core box molds completes the sand shooting process, the sand shooting table descends from station 3 to station 3.1, waiting for the next core box mold; When the core box is located at the buffer position of the filter workbench at station 2, it waits; if there is a mold at station 3.1, the core box mold continues to wait at station 2; if there is no mold at station 3.1, the core box mold automatically moves from station 2 to station 3.1.
[0018] The installation steps of three sets of core box molds include: Execute the core box installation program. The first set of core box molds moves from station 0 of the preparation workbench to station 3.1 and station 3 of the sand shooting workbench, station 4 of the air blowing workbench, and then to station 1 of the mold opening and closing workbench, and then waits at station 1.1. The second set of core box molds enters the installation program, and moves from station 0 of the preparation workbench to station 3.1 and then to station 2 to wait; then the third set of core box molds enters the installation program, and moves from station 0 to station 3.1; at this time the installation program ends.
[0019] When the core shooting machine is installed with multiple core box molds, the core box molds only move during the installation process, and no sand shooting and other processes are performed; when the program is in the production state, each device can perform core making work normally.
[0020] The steps of the core making process of three sets of core box mold cycles include: After the core box mold is installed, the core shooting machine presses the production button to enter the production operation program. The third set of core box molds rises from station 3.1 to station 3 for sand shooting, and moves to station 4 for air blowing after completing the sand shooting process. At this time, the empty sand shooting workbench at station 3 drops to station 3.1, and the second set of core box molds at station 2 has been waiting in place until it is detected that the core box mold at station 3.1 is empty, then it automatically moves to the sand shooting workbench at station 3.1, rises from station 3.1, tightens and puts in place, and directly presses the core box to complete the station installation of the core box mold at station 3, and performs the sand shooting process; the first set of core box molds at station 1.1 has also been waiting in place until it is detected that the mold at station 2 is empty, then it automatically moves to the transition workbench at station 2; after the third set of core box molds completes the air blowing process, it moves from station 4 to station 1, and the second set of molds moves when the sand shooting process is completed and station 4 is an empty mold. Enter station 4 for the air blowing process. At this time, the mold in station 3 is empty, and its sand shooting workbench automatically descends to station 3.1. The first set of molds located in station 2 detects that there is a sand shooting workbench in station 3.1 and the mold is empty, so it moves to station 3.1, automatically rises, tightens, and pushes the core box to carry out the sand shooting process after arriving at station 3; the third set of core box molds automatically descends to station 1.1 for mold closing and core returning after the mold opening and closing workbench in station 1 carries out the mold opening and core pushing process; the second set of core box molds moves to station 1 to continue the mold opening and core pushing process after completing the air blowing process; the first set of core box molds moves to station 4 to carry out the air blowing process after completing the sand shooting process; the third set of core boxes that have passed the core making process continue to be executed in subsequent cycles at station 1.1, and the second set of core box molds and the first set of core box molds are the same. The three sets of core box molds cycle up and down in turn to perform each core making process; the stagnation time of the equipment is reduced and the production efficiency is improved.
[0021] During shutdown, when the third set of core box molds runs to station 3.1, press the stop button, and the set of molds stops at station 3.1. The second set of core box molds runs to station 2 and automatically stops here. If the first set of molds is located at station 1.1, the program ends. If the first set of molds is still executing other processes, the program ends when it is completed and falls to station 1.1. When disassembling the core box mold, press the demoulding button, and the three sets of molds located at stations 3.1, 2 and 1.1 leave the production line one by one.
[0022] Whenever the core making process is completed and moves to process 1, the mold opening and core pushing process, the robot arm 1 waits in advance above the core box, and does not need to wait for the core box to push up the core before the robot arm takes the core; the speed is increased, when pushing the core, the machine equipment pushes the sand core directly onto the robot arm, and the sand core falls directly onto the robot arm, and the robot arm instantly locks the sand core. After the program detects the locking signal, the core box falls back, which greatly reduces the core taking time; the robot arm is equipped with a rubber ring; the robot arm grabs the sand core and moves to the coating machine for coating, and then returns to the core box to wait for the next batch of completed sand cores; the robot arm 2 moves to the coating dipping machine and waits for the sand core coating to be completed before grabbing it and transporting it to the pallet conveying equipment for palletizing; the palletized sand core is transported to the subsequent sequence by the pallet conveying equipment. The robot arm is also equipped with a rotating mechanism, and the robot arm can rotate, lift, and move left and right.
[0023] When the robot stacks the sand cores, it grabs the sand cores and arranges them closely; that is, it ensures that there is at least one sand core placed next to it in close contact. Because multiple sand cores can be produced in a core box at one time, the robot grabs multiple sand cores in the same core box at the same time, and there is a gap between each adjacent sand core, so the sand cores must be closely arranged during stacking to prevent the sand cores from collapsing. The robot is taught through the program to demonstrate the stacking process, and then the robot can automatically perform close arrangement; the stacking efficiency is greatly improved.
[0024] As shown in the attached figure, this is an example of a top view of sand core stacking. There are gaps between each sand core, and each group of sand cores is placed crosswise to ensure that each sand core must have other sand cores closely adjacent to it. This ensures the close arrangement and stability of the sand cores, and enables the robot to directly grab the same batch of sand cores for simultaneous stacking, which improves the stacking efficiency and saves storage space.
