Description

Technical Field

[0001] This utility model relates to casting manufacturing, specifically to a horizontal multi-point core shooter for castings with a cleaning function. Background Technology

[0002] A core shooter is a casting equipment used to manufacture sand cores. The working principle of a core shooter is to 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. Cores manufactured by core shooters have precise dimensions and smooth surfaces, and are widely used in the casting field.

[0003] The sand used in the core shooter is mostly stored in its hopper. After long-term use, the sand adhering to the inner wall of the hopper needs to be cleaned.

[0004] According to the search, a core shooting machine for making metal castings with publication number CN221848582U is described. It uses motor B to drive transmission rod B to rotate, which in turn drives horizontal plate to rotate, and then the horizontal plate drives scraper to rotate, thereby scraping away the sand adhering to the inner wall of the hopper.

[0005] However, since the scraper in the above method is located inside the hopper when not in use, it affects the volume of the hopper. At the same time, the long-term contact between the sand and the scraper makes it easy for sand to adhere to the scraper and cause wear.

[0006] Therefore, we propose a horizontal multi-point core shooter for castings with a cleaning function. Utility Model Content

[0007] To overcome the above-mentioned defects, this utility model provides a horizontal multi-point core shooter for castings with a cleaning function. It solves the technical problem in the prior art that when the scraper is not in use, it is located inside the hopper, which affects the volume of the hopper.

[0039] like Figures 1-5 As shown, it illustrates a horizontal multi-point core shooter for castings with a cleaning function in one embodiment of the present invention;

[0040] In some examples, including:

[0041] The core shooting machine body 1 has a support frame 3 fixedly connected to the top of the hopper 2 of the core shooting machine body 1. One end of the support frame 3 is vertically rotatably connected to the transmission shaft 4. The bottom of the outer side of the transmission shaft 4 is fixedly connected to the assembly plate 5. The bottom of the end of the assembly plate 5 away from the transmission shaft 4 is fixedly connected to the assembly seat 6.

[0042] Cleaning component 7 is assembled at the bottom of the mounting base 6. Cleaning component 7 is used to clean the sand material on the inner wall of the hopper 2 in conjunction with the rotation of the drive shaft 4.

[0043] The drive motor 8 is fixedly connected to the top of the support frame 3. The output end of the drive motor 8 is fixedly connected to the drive spur gear 9. The outer side of the drive shaft 4 is fixedly connected to the reduction spur gear 10, and the reduction spur gear 10 is meshed with the drive spur gear 9.

[0044] Among them, the core shooting machine body 1 is a frame body welded from crossbeams, columns, etc., which provides equipment stability and support. The crossbeams integrate components such as hopper 2, sand valve and clamping cylinder to form a sand supply and air supply system. The core components include sand shooting cylinder, air storage tank, sand shooting valve and nozzle, which undertake the high-speed sand shooting function. Subsequently, high-pressure air is released instantly through sand shooting valve to push the core sand to be evenly injected into the core box, forming the sand core outline and completing compaction. This is a mature existing technology and will not be described in detail here.

[0045] For example, such as Figure 4 As shown, the cleaning component 7 includes:

[0046] Support shaft 11 is rotatably connected to the bottom end of assembly base 6. Scraper 12 is fixedly connected to the middle of assembly base 6. Extension frame 13 is fixedly connected to the end of assembly plate 5 near support shaft 11.

[0047] The transmission screw 14 is vertically rotatably connected inside the extension frame 13. The outer side of the extension frame 13 is threadedly connected to the displacement frame 15. One end of the displacement frame 15 is fixedly connected to the guide shaft 16. The end of the support shaft 11 near the guide shaft 16 is fixedly connected to the eccentric plate 17. The eccentric plate 17 has a through groove 18 inside, and the guide shaft 16 is also movably connected inside the through groove 18.

[0048] The jetting assembly is located on one side of the scraper 12 and is used to blow sand off the inner wall of the hopper 2.

[0049] For example, such as Figure 5 As shown, an inner cavity is provided at scraper 12, and a scraper is fixedly connected to the inner cavity. The scraper is in contact with the inner wall of hopper 2. The scraper can ensure the contact effect with the inner wall of hopper 2. When the scraper moves along the inner wall of hopper 2, it can scrape off the sand attached to hopper 2. The scraper is provided with a wear-resistant layer to ensure the service life of the scraper.

[0050] For example, such as Figure 5 As shown, a linear guide rod is vertically fixed inside the extension frame 13, and the displacement frame 15 is also slidably connected to the outside of the linear guide rod. By setting the linear guide rod, the displacement of the displacement frame 15 can be effectively guided, preventing the displacement frame 15 from rotating with the transmission screw 14 and ensuring the stability of the displacement of the displacement frame 15.

[0051] like Figure 5 As shown, this illustrates a horizontal multi-point core shooter for castings with a cleaning function in another embodiment of the present invention. The air jet assembly includes:

[0052] The nozzle 19 is fixedly connected to one side of the scraper 12. A transmission pipe 20 is passed through the middle of the drive shaft 4. The end of the transmission pipe 20 near the nozzle 19 is connected to the top of the nozzle 19.

[0053] The fan 21 has an air supply pipe 22 fixedly connected to its output end, and the end of the air supply pipe 22 away from the fan 21 is rotatably connected to the top of the fan 21.

[0054] For example, such as Figure 5 As shown, multiple air jet holes are provided on the outer side of the nozzle 19, and a nozzle is fixedly connected inside each air jet hole. By setting the nozzle, the airflow entering the nozzle 19 can be discharged over a wider range, reducing the blind spot of the nozzle 19. In addition, a baffle can be set inside the nozzle to prevent sand from entering the nozzle.

[0055] For example, such as Figure 4As shown, the transmission pipe 20 includes a rigid section and a flexible section. The rigid section is fixedly connected to the drive shaft 4, and the flexible section is connected to the nozzle 19. Through the connection between the flexible section of the transmission pipe 20 and the nozzle 19, the rotation of the scraper 12 will not be affected without affecting the airflow transmission.

[0056] For example, such as Figure 4 As shown, a filter cartridge is fixedly connected to the input end of the fan 21, and an activated carbon layer is fixedly connected inside the filter cartridge. By setting the activated carbon layer, the airflow entering the fan 21 can be pre-filtered to prevent debris and other impurities from entering the fan 21 and affecting the operation of the fan 21.

[0057] Working principle: When the sand material is heavily attached to the inner wall of the hopper 2, the transmission screw 14 is rotated first to cause the displacement frame 15 to move vertically along the transmission screw 14. Since the guide shaft 16 is connected inside the through groove 18, when the displacement frame 15 moves, it can press the eccentric plate 17 by means of the adaptive movement of the guide shaft 16 inside the through groove 18. Since the eccentric plate 17 is supported by the support shaft 11, it can drive the scraper 12 to flip inside the core shooter body 1 through the support shaft 11 until the scraper at the scraper 12 is tightly attached to the inner wall of the core shooter body 1.

[0058] The drive motor 8 is restarted to cause the drive spur gear 9 to move the reduction spur gear 10, which in turn drives the drive shaft 4 to rotate. With the drive shaft 4 connected to the assembly plate 5, the scraper can move along the inner wall of the hopper 2, thereby scraping off the sand on the inner wall of the hopper 2. At the same time, the blower 21 can be started to inject airflow into the transmission pipe 20, and then through the transmission pipe 20 to the nozzle 19, and finally sprayed onto the inner wall of the hopper 2 through the nozzle 19, thereby assisting the scraper operation.

[0059] After cleaning, rotating the transmission screw 14 drives the displacement frame 15 to move upward, so that the scraper 12, supported by the support shaft 11, flips to the top of the hopper 2, preventing the scraper 12 from continuously contacting the sand inside the hopper 2, ensuring the application effect of the scraper 12, and not occupying the sand storage space inside the hopper 2.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
