Description

Technical Field

[0001] This utility model relates to the field of casting separation technology, and more specifically, to a casting separation and unloading device. Background Technology

[0002] In the foundry industry, after castings are formed in a casting mold, they need to be separated and unloaded from the casting mold. This is especially true for sand castings. After the casting parts are formed inside the sand mold formed by pounding sand, a casting separation and unloading device is usually needed to remove one or more castings from the sand mold.

[0003] Currently, sand casting separation and blanking devices typically refer to hammers. When removing castings from a sand mold, the hammer is usually used to strike the sand mold, loosening it and thus separating and blanking the castings. While this method can achieve the separation and blanking of castings from a sand mold, it is relatively cumbersome to operate. Moreover, if there are multiple castings in the sand mold, hammering becomes even more time-consuming and laborious, and there is a risk of missing castings. Therefore, we propose a casting separation and blanking device. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a casting separation and blanking device to solve the technical problem that the current sand casting separation and blanking device is not convenient to use.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a casting separation and unloading device, including a collection box, a number of spring supports are equidistantly arranged around the top of the collection box, a screening platform is arranged on the top of the collection box through the spring supports, two sets of vibrating motors are symmetrically arranged at the bottom of the screening platform, a placement seat is arranged in the center of the top of the screening platform, and a fixing structure is rotatably arranged on both sides of the placement seat.

[0006] The screening platform includes a rectangular shell and a separation screen.

[0007] This invention, through its designed collection box, screening platform, vibrating motor, placement seat, and fixing structure, allows for the direct placement of the sand mold and its outer shell onto the placement seat during the separation and unloading of castings from the sand mold. The outer shell is then secured by the fixing structure. The vibrating motor, in conjunction with spring supports, causes the screening platform to vibrate. This loosens the sand within the outer shell, forming granular red sand. The loosened red sand falls through the screening platform into the collection box for storage and later use. The casting remains on the screening platform, thus achieving rapid separation and unloading of sand mold castings. This facilitates quick collection of castings and improves the convenience of sand mold casting separation and unloading. The screening platform of this invention consists of a rectangular shell and a separation mesh plate, separating… The screen plate is triangular in shape, and several sets of inclined baffles are equidistantly arranged on the two inclined surfaces of the separating screen plate. The baffles are arranged in an alternating staggered manner. Then, a serpentine channel is formed inside the rectangular shell through the baffles. Therefore, when the sand mold and casting are loosened by vibration, they will fall directly onto the separating screen plate inside the rectangular shell. Then, the red sand and casting will slowly fall along the serpentine channel. The serpentine channel can greatly increase the travel of the red sand and casting, thus ensuring that the loosened sand mold can be fully screened by the separating screen plate during the slow fall of the serpentine channel. Then, it falls into the collection box through the rectangular opening. Finally, the casting is automatically discharged from the openings on both sides of the rectangular shell. Thus, the automatic collection effect of casting can be achieved during the sand mold casting separation process, further improving the separation and discharge effect of sand mold casting, and making it more convenient and faster to use.

[0008] Preferably, the bottom of the rectangular shell has several sets of rectangular openings at equal intervals, and the top center of the rectangular shell has a rectangular discharge port, which corresponds to the placement seat.

[0009] Preferably, the separating mesh plate is triangular in shape, and several sets of baffles are equidistantly arranged on the two inclined surfaces of the separating mesh plate. The baffles are arranged at an incline, and a serpentine channel is formed inside the rectangular shell through the baffles.

[0010] Preferably, a support plate is arranged at the center of the bottom of the separation mesh plate, and the support plate is connected to the rectangular shell.

[0011] Preferably, the placement seat is a rectangular frame structure, and the length and width of the inner hole of the placement seat are the same as the length and width of the rectangular discharge port. Limiting baffles are arranged on the front and rear sides of the top of the placement seat.

[0012] Preferably, the fixing structure includes a U-shaped bracket, which is rotatably arranged on the placement seat. A pressure plate is slidably arranged on the U-shaped bracket. An adjusting screw is rotatably arranged at the center of the U-shaped bracket, and the adjusting screw passes through the pressure plate. The pressure plate is L-shaped.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through its designed collection box, screening platform, vibrating motor, placement seat, and fixing structure, allows for the direct placement of the sand mold and its outer shell on the placement seat when separating and unloading castings from the sand mold. The sand mold shell is then fixed by the fixing structure, and the vibrating motor, in conjunction with the spring support, causes the screening platform to vibrate. This loosens the sand within the outer shell, forming granular red sand. The loosened red sand falls through the screening platform into the collection box for storage and later use. The casting remains on the screening platform, thus achieving rapid separation and unloading of sand mold castings. This facilitates quick collection of castings and improves the convenience of sand mold casting separation and unloading, solving the technical problem of the current inconvenient use of sand mold casting separation and unloading devices. Therefore, this utility model offers the advantage of more convenient sand mold casting separation and unloading.

[0015] 2. The screening platform of this utility model consists of a rectangular shell and a separation screen. The separation screen is triangular in shape, and several sets of inclined baffles are equidistantly arranged on the two inclined surfaces of the separation screen. The baffles are arranged in an alternating staggered manner. Then, a serpentine path is formed inside the rectangular shell through the baffles. Therefore, when the sand mold and casting are loosened by vibration, they will fall directly onto the separation screen inside the rectangular shell. Then, the red sand and casting will slowly fall along the serpentine path. The serpentine path can greatly increase the travel of the red sand and casting, thus ensuring that the loosened sand mold can be fully screened by the separation screen during the slow fall along the serpentine path. Then, it falls into the collection box through the rectangular opening. Finally, the casting is automatically discharged from the openings on both sides of the rectangular shell. Thus, the automatic collection effect of casting can be achieved during the sand mold casting separation process, further improving the separation effect of sand mold casting, and making it more convenient and faster to use.

[0023] like Figures 1 to 5 As shown, this utility model relates to a casting separation and unloading device, including a collection box 1. Several sets of spring supports 2 are equidistantly arranged around the top of the collection box 1. A screening platform 3 is arranged on the top of the collection box 1 through the spring supports 2. Two sets of vibrating motors 4 are symmetrically arranged at the bottom of the screening platform 3. A placement seat 5 is arranged in the center of the top of the screening platform 3. Fixing structures 6 are rotatably arranged on both sides of the placement seat 5. When separating and unloading castings in a sand mold, the sand mold and its outer shell can be directly placed on the placement seat 5. Then, the sand mold shell is fixed by the fixing structure 6. Then, the vibrating motors 4 are controlled to work. With the cooperation of the spring supports 2, the screening platform 3 will vibrate. At this time, the sand mold shell fixed on the placement seat 5 will loosen and form granular red sand. The loosened red sand will fall into the collection box 1 through the screening platform 3 for storage for later use. The casting will remain on the screening platform 3, thereby realizing the rapid separation and unloading of sand mold castings, making it convenient for personnel to quickly collect the castings and improving the convenience of sand mold casting separation and unloading.

[0024] Specifically, the placement seat 5 is a rectangular frame structure, and the length and width of the inner hole of the placement seat 5 are the same as the length and width of the rectangular material discharge port 702. Limiting baffles 501 are arranged on the front and rear sides of the top of the placement seat 5. The placement seat 5 is used to support and place the sand mold shell, and the limiting baffles 501 are used to block and limit its movement in the front and rear.

[0025] Furthermore, the fixing structure 6 includes a U-shaped bracket 601, which is rotatably arranged on the placement seat 5. A pressure plate 602 is slidably arranged on the U-shaped bracket 601. An adjusting screw 603 is rotatably arranged in the center of the U-shaped bracket 601, and the adjusting screw 603 passes through the pressure plate 602. The pressure plate 602 is L-shaped. When the sand mold shell is placed on the placement seat 5, the U-shaped bracket 601 can be rotated, and then the U-shaped bracket 601 will stick to both sides of the sand mold shell. Then, the adjusting screw 603 is turned, and the pressure plate 602 will descend. The L-shaped end of the pressure plate 602 will press against the sand mold shell, thereby fixing the sand mold shell on the placement seat 5, that is, fixing the sand mold.

[0026] In this embodiment of the utility model, the screening platform 3 includes a rectangular shell 7 and a separating screen plate 8; the bottom of the rectangular shell 7 is provided with several sets of rectangular openings 701 at equal intervals, and the top center of the rectangular shell 7 is provided with a rectangular discharge port 702, which corresponds to the placement seat 5; the separating screen plate 8 is triangular in shape, and several sets of baffles 801 are arranged at equal intervals on the two inclined surfaces of the separating screen plate 8. The baffles 801 are arranged at an incline, and a serpentine channel is formed inside the rectangular shell 7 through the baffles 801; the sand mold and castings loosened by vibration will fall directly into the rectangular shell 7 through the rectangular discharge port 702. The red sand and castings are placed on the separating screen plate 8, and then the red sand and castings slowly fall along the serpentine path inside the rectangular shell 7. The serpentine path can greatly increase the travel of the red sand and castings, so that the loose sand mold can be fully screened by the separating screen plate 8 during the slow fall along the serpentine path. Then it falls into the collection box 1 through the rectangular opening 701. Finally, the castings are automatically discharged from the openings on both sides of the rectangular shell 7. Thus, the automatic collection effect of castings can be achieved during the sand mold casting separation process, further improving the separation effect of sand mold castings, and making it more convenient and faster to use.

[0027] Specifically, a support plate 802 is arranged at the center of the bottom of the separation mesh plate 8, and the support plate 802 is connected to the rectangular shell 7. The support plate 802 is mainly used to support the separation mesh plate 8 and ensure the installation stability of the separation mesh plate 8.

[0028] Working principle: This embodiment provides a casting separation and unloading device. First, when separating and unloading castings in a sand mold, the sand mold and its outer shell can be placed directly on the placement seat 5. Then, the sand mold shell is fixed by the fixing structure 6. Then, the vibration motor 4 is controlled to work. With the cooperation of the spring support 2, the screening platform 3 will vibrate. At this time, the sand in the sand mold shell fixed on the placement seat 5 will be loosened, forming granular red sand. The loosened red sand will fall into the collection box 1 through the screening platform 3 for storage for later use. The casting will be retained on the screening platform 3, thereby realizing the rapid separation and unloading of sand mold castings, making it easy for personnel to quickly collect the castings and improving the convenience of sand mold casting separation and unloading.

[0029] Secondly, the loosened sand mold and castings will fall directly into the separation screen plate 8 inside the rectangular shell 7 through the rectangular discharge port 702. Then, the red sand and castings will slowly fall along the serpentine path inside the rectangular shell 7. The serpentine path can greatly increase the travel distance of the red sand and castings, thus ensuring that the loosened sand mold can be fully screened by the separation screen plate 8 during the slow fall along the serpentine path. Then, it falls into the collection box 1 through the rectangular opening 701. Finally, the castings are automatically discharged from the openings on both sides of the rectangular shell 7. Thus, the automatic collection effect of castings can be achieved during the sand mold casting separation process, further improving the separation and discharge effect of sand mold castings, making it more convenient and faster to use.
