Description

Technical Field

[0001] The present invention relates to the technical field of casting equipment, and in particular to a fully automatic and efficient core shooter. Background Art

[0002] Core shooters are widely used in the casting industry and are applicable to both hot core boxes and cold core boxes. The working principle of a core shooter is to shoot a core sand mixture with a liquid or solid thermosetting resin as a binder into a core box mold. After the core sand hardens in the mold, it is taken out to obtain a core. At room temperature, the core-making method of quickly hardening the core sand in the core box by blowing air is called the cold core box method. The cold core box method is an efficient process for manufacturing core sand, with advantages such as high efficiency, energy conservation, and good working conditions, and is now widely used in casting production.

[0003] An existing core shooter includes a base, a column component, a sand shooting device, and a die carrier component. Among them, the base mainly plays a supporting role. Components such as a sand cylinder, a sand hopper, a sand valve component, and a pressing cylinder are arranged on the column component to form a sand supply and air supply system for core making. The sand shooting device includes components such as a sand cylinder, an air valve, a sand cylinder frame, a shooting head, and a sand shooting plate. The die carrier component mainly includes a fixed template, a movable template, left and right mounting brackets, and components such as guide columns, guide sleeves, ejector rods, and a mold clamping cylinder. During operation, first start the mold clamping cylinder to close the movable template and the fixed template. After closing the mold, the pressing cylinder presses the sand cylinder against the upper plane of the core box, open the sand shooting valve to shoot sand. After exhausting and shooting sand, loosen the pressing cylinder and the mold clamping cylinder to open the mold. After opening the mold, the formed sand is taken out manually to complete the sand shooting work.

[0004] During the use of the above core shooter, every time a sand shooting work is completed, it is necessary to clean the fixed template and the movable template. Only after the cleaning is completed can the next sand shooting work be carried out, resulting in the inability to continuously carry out the sand shooting work of the core shooter, which is likely to affect the continuity of the core preparation process and thus reduce the core preparation efficiency. Summary of the Invention

[0038] Refer to Figure 3 and Figure 4 , when the core shooter is working, the rotary cylinder 82 is started to drive the rotating block 83 to rotate, so that the insertion rod 84 and the connecting seat 85 rotate synchronously. At the same time, under the combined action of the connecting spring 86, the fixed rod 5 and the sliding rod 6, it helps the sliding seat 7 to reciprocate along the shape of the movable track 2.

[0039] Refer to Figure 3 and Figure 4The sliding seat 7 is provided with a plug assembly 9, which includes a driving cylinder 91 and a plug connector 92.

[0043] Reference Figure 1 and Figure 6, when an installation base 3 moves below the mounting bracket 10, the piston rod of the pressing cylinder 115 extends, driving the opening of the sand shooting head 114 to align with the sand inlet on the moving mold 43 and the fixed mold 42 in the mold closing state. At the same time, the sand shooting valve 112 is started, so that the core sand mixture in the sand hopper 111 is injected into the moving mold 43 and the fixed mold 42 through the corrugated pipe 113 and the sand shooting head 114, thus completing the sand shooting process. After a set of mold components 4 finishes sand shooting, the sliding seat 7 drives this set of mold components 4 to move to the next working station, and then drives the next set of mold components 4 to move to the sand shooting position, which helps to improve the continuity of the sand shooting work of the core shooter, thus helping to improve the continuity of the core preparation process, and further helping to improve the preparation efficiency of the core.

[0044] Refer to Figure 1 , at a corner of the frame 1 near the movable track 2 and adjacent to the mounting bracket 10, a blanking assembly 12 is provided. The blanking assembly 12 includes a receiving cylinder 121 and a receiving plate 122.

When the sliding seat 7 moves to the bottom of the mounting seat 3, the piston rod of the driving cylinder 91 extends, driving the plug connector 92 to pass through the clearance opening 14 upward and insert into the plug hole 13, so that the sliding seat 7 drives the mounting seat 3 to move synchronously, and then helps to drive the multiple sets of mold assemblies 4 to move in sequence along the movable track 2.

[0049] When a mounting seat 3 moves to the bottom of the mounting frame 10, the piston rod of the clamping cylinder 115 extends, driving the opening of the sand shooting head 114 to align with the sand inlet on the movable mold 43 and the fixed mold 42 in the mold closing state, and at the same time starting the sand shooting valve 112, so that the core sand mixture in the sand bucket 111 is shot into the movable mold 43 and the fixed mold 42 through the bellows 113 and the sand shooting head 114, thereby completing the sand shooting process. When a group of mold assemblies 4 are completed after sand shooting, the sliding seat 7 drives the group of mold assemblies 4 to move to the next station, and then drives the next group of mold assemblies 4 to move to the sand shooting position, which helps to improve the continuity of the core shooting machine in the sand shooting work, thereby helping to improve the continuity of the core preparation process, and then helps to improve the efficiency of core preparation.

[0050] When a mounting seat 3 moves to one side of the material receiving cylinder 121, the mold closing cylinder 44 drives the movable mold 43 to gradually move away from the movable mold 43, so that the movable mold 43 and the fixed mold 42 gradually turn into the open mold state; at the same time, the piston rod of the material receiving cylinder 121 extends, driving the material receiving plate 122 to move to the bottom of the movable mold 43 and the fixed mold 42, thereby facilitating the use of the material receiving plate 122 to receive and discharge the prepared core after the mold is opened.

[0051] When a mounting seat 3 moves to the side of the first mechanical arm 17, the first mechanical arm 17 drives the cleaning air gun 18 to clean the inside of the movable mold 43 and the fixed mold 42, thereby helping to remove residual impurities inside the movable mold 43 and the fixed mold 42, and then helping to ensure the quality of the next round of core preparation. When a mounting seat 3 moves to the side of the second mechanical arm 19, the second mechanical arm 19 drives the spray gun 20 to spray the molding sand release agent inside the movable mold 43 and the fixed mold 42, thereby helping to improve the convenience of the core demolding process, and then helping to improve the efficiency of core preparation.
