Description

Technical Field

[0001] This utility model relates to the field of core processing technology, and in particular to a purging mechanism for a core shooter. Background Technology

[0002] Core shooters are equipment used in the foundry industry to manufacture sand cores. They inject a core sand mixture with liquid or solid thermosetting resin as a binder into a heated core box. The sand core is preheated in the core box and quickly hardens to a certain thickness (about 5-10mm). Then it is removed to form a high-quality sand core product with a smooth surface and accurate dimensions.

[0003] After the sand core is made, the workers need to manually remove the sand core and then manually blow the two templates with a blow gun to remove the core sand that may be adsorbed on the inner cavity of the template. However, manually blowing the two templates one by one takes a long time, resulting in low work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a purging mechanism for a core shooting machine, which improves work efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: It includes a machine body, a first template arranged vertically, and a second template arranged vertically. A first cylinder for driving the first template to move is arranged horizontally on the machine body. A second cylinder for driving the second template to move is arranged horizontally on the machine body. A blowing component for blowing the first template and the second template is movably arranged vertically on the machine body. A driving component for driving the blowing component to move vertically is provided on the machine body. The driving component can drive the blowing component to descend below the first template and the second template.

[0006] A further feature of this invention is that the purging component includes a lifting cylinder arranged vertically and purging pipes symmetrically arranged vertically on both sides of the lifting cylinder. The purging pipes have several air outlets. A blower is provided on the machine body, and an air supply hose is provided between the blower and the purging pipes.

[0007] A further feature of this invention is that the driving component includes a lifting screw rotatably mounted on the machine body in a vertical direction and a first rotating wheel mounted at the bottom of the lifting screw. The inner wall of the lifting cylinder cooperates with the lifting screw. A second rotating wheel is rotatably mounted on the machine body. A synchronous belt is provided between the first rotating wheel and the second rotating wheel. A drive motor for driving the second rotating wheel is provided on the machine body.

[0008] A further feature of this invention is that the opening direction of the air outlet is obliquely upward.

[0009] A further feature of this invention is that: a first infrared emitter is provided at the bottom of the lifting cylinder, and a first infrared receiver is provided on the machine body to cooperate with the first infrared emitter. The first infrared receiver is electrically connected to the blower. When the first infrared emitter rises to the horizontal plane where the first infrared receiver is located, the blowing component is located between the first template and the second template.

[0010] A further feature of this invention is that: a second infrared emitter is provided at the bottom of the second template, and a second infrared receiver is provided on the body to cooperate with the second infrared emitter. The second infrared receiver is electrically connected to the drive motor. When the second infrared emitter is located directly above the second infrared receiver, there is a set distance between the first template and the second template.

[0011] A further feature of this invention is that a first housing is provided on the machine body, and the first rotating wheel, the second rotating wheel, and the synchronous belt are located inside the first housing.

[0012] A further feature of this invention is that a cylindrical telescopic cover is provided vertically between the bottom end of the lifting cylinder and the first housing, and the lifting screw is located inside the telescopic cover.

[0013] A further feature of this invention is that the telescopic cover is made of plastic material.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up a purging component and a driving component, after the core shooting process is completed, the first cylinder is first opened to drive the first template to move away from the second template. Then, the worker manually removes the sand core from the second template. After that, the second cylinder is opened to drive the second template to move away from the first template, creating a certain distance between the first and second templates. Then, the driving component is opened to drive the purging component to rise between the first and second templates. The two symmetrically arranged purging components blow gas into the first and second templates respectively to remove any core sand that may be attached to the first and second templates. After purging, the driving component drives the purging component to move downwards to below the first and second templates. Therefore, by setting up a purging component and a driving component, the purging component can rise and simultaneously purge the first and second templates, eliminating the need for workers to purge the first and second templates sequentially, thereby improving purging efficiency and work efficiency. Furthermore, the purging efficiency of the first and second templates can be further improved by setting the purging range of the purging component, thus further improving work efficiency.

[0016] 2. By setting up purge pipes, air vents, etc., when purging the first template and the second template, multiple air vents on the vertically set purge pipes can simultaneously purge various parts of the first template and the second template, thereby improving the purging efficiency of the first template and the second template and achieving the goal of improving work efficiency.

[0017] 3. By setting up a first infrared emitter and a second infrared emitter, after core shooting is completed, the first cylinder is opened to drive the first template to move away from the second template. Then, the worker manually removes the sand core from the second template. After that, the second cylinder is opened to drive the second template to move away from the first template. When the second infrared emitter at the bottom of the second template moves directly above the second infrared receiver, the second infrared receiver receives a signal and drives the drive motor to rotate. Then, through the synchronous belt and the first rotating wheel, the lifting screw rotates, causing the lifting cylinder to lift the blowing pipe. When the lifting cylinder rises to the same height as the first infrared emitter and the first infrared receiver at the bottom of the lifting cylinder, the first infrared receiver receives a signal and controls the blower to blow air. Air enters the blowing pipe through the air supply hose and is blown out from the air outlet to blow the first and second templates. When the lifting cylinder rises to the top of the lifting screw, the lifting screw can rotate in the opposite direction according to the set program. As the lifting cylinder descends, air continues to blow out from the vents to clean the first and second templates until the first infrared emitter at the bottom of the cylinder reaches the height of the first infrared receiver. At this point, the first infrared receiver receives a signal again and controls the blower to stop working. Finally, the lifting screw drives the lifting cylinder to descend below the first and second templates and stops rotating. Therefore, by setting up the first and second infrared emitters, the drive motor is automatically driven to rotate as the second template moves away from the first template, thereby driving the blowing pipe to rise along the lifting screw. During the rise, the blower is automatically turned on to clean the vents. Afterward, according to the set time, the drive motor drives the blowing pipe to descend, and the blower is automatically turned off during the descent. Therefore, the entire cleaning process of the first and second templates can be achieved automatically through the cooperation of the first infrared emitter and the first infrared receiver, eliminating the need for manual operation by workers and improving work efficiency.

[0024] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] This utility model provides a purging mechanism for a core shooting machine, such as... Figures 1 to 4 As shown, the device includes a body 1, a first template 2 arranged vertically, and a second template 3 arranged vertically. A first cylinder 4 for driving the first template 2 to move is arranged horizontally on the body 1. A second cylinder 5 for driving the second template 3 to move is arranged horizontally on the body 1. A blowing component 6 for blowing the first template 2 and the second template 3 is movably arranged vertically on the body 1. A driving component 7 for driving the blowing component 6 to move vertically is provided on the body 1. The driving component 7 can drive the blowing component 6 to descend below the first template 2 and the second template 3.

[0026] Furthermore, the purging component 6 includes a lifting cylinder 6a arranged vertically and purging pipes 6b symmetrically arranged vertically on both sides of the lifting cylinder 6a. The purging pipes 6b are provided with a plurality of air outlets 8. The body 1 is provided with a blower 9, and an air supply hose 10 is provided between the blower 9 and the purging pipes 6b.

[0027] Furthermore, the driving component 7 includes a lifting screw 7a rotatably mounted on the machine body 1 in a vertical direction and a first rotating wheel 7b disposed at the bottom of the lifting screw 7a. The inner wall of the lifting cylinder 6a cooperates with the lifting screw 7a. A second rotating wheel 11 is rotatably mounted on the machine body 1. A synchronous belt 12 is disposed between the first rotating wheel 7b and the second rotating wheel 11. A drive motor 13 for driving the second rotating wheel 11 is disposed on the machine body 1.

[0028] Furthermore, the opening direction of the air outlet 8 is obliquely upward.

[0029] Furthermore, a first infrared emitter 14 is provided at the bottom of the lifting cylinder 6a, and a first infrared receiver 15 is provided on the body 1 to cooperate with the first infrared emitter 14. The first infrared receiver 15 is electrically connected to the blower 9. When the first infrared emitter 14 rises to the horizontal plane where the first infrared receiver 15 is located, the blowing component 6 is located between the first template 2 and the second template 3.

[0030] Furthermore, a second infrared emitter 16 is provided at the bottom of the second template 3, and a second infrared receiver 17 is provided on the body 1 to cooperate with the second infrared emitter 16. The second infrared receiver 17 is electrically connected to the drive motor 13. When the second infrared emitter 16 is located directly above the second infrared receiver 17, there is a set distance between the first template 2 and the second template 3.

[0031] Furthermore, the machine body 1 is provided with a first housing 18, and the first rotating wheel 7b, the second rotating wheel 11 and the synchronous belt 12 are located inside the first housing 18.

[0032] Furthermore, a cylindrical telescopic cover 19 is provided vertically between the bottom end of the lifting cylinder 6a and the first housing 18, and the lifting screw 7a is located inside the telescopic cover 19.

[0033] Furthermore, the telescopic cover 19 is made of plastic material.

[0034] After core shooting is completed, the first cylinder 4 is opened to drive the first template 2 to move away from the second template 3. Then, the worker manually removes the sand core from the second template 3. After that, the second cylinder 5 is opened to drive the second template 3 to move away from the first template 2. When the second infrared emitter 16 at the bottom of the second template 3 moves directly above the second infrared receiver 17, the second infrared receiver 17 receives the signal and drives the drive motor 13 to rotate. Then, through the synchronous belt 12, the first rotating wheel 7b, etc., the lifting screw 7a rotates, causing the lifting cylinder 6a to drive the blowing pipe 6b to rise. When the lifting cylinder... When the first infrared emitter 14 and the first infrared receiver are at the same height at the bottom of the lifting cylinder 6a, the first infrared receiver 15 receives the signal and controls the blower 9 to blow air, so that air enters the purging pipe 6b through the air supply hose 10 and is blown out from the air outlet 8 to purge the first template 2 and the second template 3. When the lifting cylinder 6a rises to the top of the lifting screw 7a, the lifting screw 7a can rotate in the opposite direction according to the set program, driving the lifting cylinder 6a to descend. During the descent of the lifting cylinder 6a, air will still be blown out from the air outlet 8 to purge the first template 2 and the second template 3 until the bottom of the lifting cylinder 6a is reached. The first infrared emitter 14 descends to the height of the first infrared receiver 15. At this point, the first infrared receiver 15 receives the signal again and controls the blower 9 to stop working. Finally, the lifting screw 7a drives the lifting cylinder 6a to descend below the first template 2 and the second template 3 and then stops rotating. (It should be noted that although the second infrared emitter 16 is always directly above the second infrared receiver 17 during the lifting process of the lifting cylinder 6a, the second infrared receiver can execute the command only once according to the set interval time, that is, drive the lifting screw 7a to rotate forward and backward for the set time. Only when the second infrared generator exceeds the set time...) When the device moves to directly above the second infrared receiver 17 again at a predetermined interval, the second infrared receiver will execute the command, i.e., drive the drive motor 13 to rotate forward and backward according to the set time. Therefore, by setting the blowing component 6 and the drive component 7, the blowing component 6 can be driven to rise and simultaneously blow the first template 2 and the second template 3, eliminating the need for workers to blow the first template 2 and the second template 3 sequentially, thereby improving the blowing efficiency and work efficiency. At the same time, the blowing efficiency of the first template 2 and the second template 3 can be further improved by setting the blowing range of the blowing component 6, thereby further improving work efficiency.

[0035] By setting up a purge pipe 6b, air outlets 8, etc., when the first template 2 and the second template 3 are purged, the multiple air outlets 8 on the vertically set purge pipe 6b purge various parts of the first template 2 and the second template 3 at the same time, thereby improving the purge efficiency of the first template 2 and the second template 3 and achieving the purpose of improving work efficiency.

[0036] By setting up a first infrared emitter 14, a second infrared emitter 16, etc., the drive motor 13 is automatically driven to rotate as the second template 3 moves away from the first template 2, thereby driving the blowing pipe 6b to rise along the lifting screw 7a. During the rising process, the blower 9 is automatically driven to open so that the air outlet 8 can blow. Then, according to the set time, the drive motor 13 drives the blowing pipe 6b to descend. During the descent process, the blower 9 is automatically driven to turn off. Therefore, the entire blowing process of the first template 2 and the second template 3 can be achieved through the cooperation between the first infrared emitter 14 and the first infrared receiver 15, realizing automatic blowing without the need for manual operation by workers, thus improving work efficiency.

[0037] By setting the air outlet 8 at an angle upward, on the one hand, since the height of the top of the air blowing pipe is lower than the height of the top of the first template 2 and the second template 3, setting the air outlet 8 at an angle upward can blow the top of the first template 2 and the second template 3, thus expanding the blowing range; on the other hand, setting the air outlet 8 at an angle upward can use the upward blowing force to blow the core sand attached to the first template 2 and the second template 3 out of the outside of the first template 2 and the second template 3 at an angle upward, thereby improving the cleaning effect on the first template 2 and the second template 3.

[0038] By setting the first housing 18 and the telescopic cover 19, the falling core sand can be prevented from adhering to the lifting screw 7a or the first rotating wheel 7b, etc., ensuring the normal operation of the lifting screw 7a, the timing belt 12, etc.

[0039] It should be noted that workers regularly clean and maintain the first infrared receiver 15 and the second infrared receiver 17 to prevent a large amount of core sand from adhering to the surface and affecting the normal operation of the receivers. In addition, the first infrared receiver, the second infrared receiver, etc. are all existing technologies. That is, after receiving infrared signals according to the set program (i.e., the set time interval, etc.), they will issue instructions to drive the associated components (i.e., drive motor 13 or blower 9).

[0040] The control methods of the first and second cylinders of this utility model can be controlled by manual start and stop switches, or automatically by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The wiring diagram of the power element and the supply of power are also common knowledge in the art. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0041] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0042] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
