Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, specifically to a sand casting device for casting processing. Background Technology

[0002] Casting is an important metalworking method. First, it obtains an initial casting through casting, much like creating a rough shape using a mold. For example, sand casting is commonly used to produce cast iron pots; molten iron is poured into a sand mold, and after cooling and solidification, the basic shape of the pot is obtained. This casting is then further processed.

[0003] Sand molds are typically used in casting processing. Molten metal is poured into the sand mold to complete the casting. Fine sand is required for the sand mold, but the sand body is not entirely composed of fine sand that meets the requirements. Therefore, the sand body needs to be screened. The common screening method is to pour the sand body onto a screen for sieving. However, the sand body accumulating together will affect the sieving effect of the screen. Therefore, a sand turning device for casting processing is proposed. Utility Model Content

Detailed Implementation

[0019] like Figures 1-4 As shown, this utility model provides a technical solution: a sand-casting device for processing castings, including a main body 1, a support leg 2 fixedly installed on the outer wall of the main body 1, a screen 3 fixedly installed on the inner wall of the main body 1, a feed trough 4 provided on the outer wall of the main body 1, a discharge port 5 opened at the bottom of the main body 1, a reciprocating mechanism 6 provided on the outer wall of the main body 1, and an auxiliary mechanism 7 provided on the inner wall of the main body 1.

[0020] The reciprocating mechanism 6 includes: a bearing rod 601, a motor 602, a slide 603, a groove rod 604, a disc 605, a block 606, a clearing rod 607, a connecting rod 608, and a pressing rod 609. The bearing rod 601 is fixedly installed on the outer wall of the main body 1, and the motor 602 is fixedly installed at the end of the bearing rod 601. A slide 603 is provided on the side wall of the main body 1, and the groove rod 604 is slidably installed on the inner wall of the slide 603. The disc 605 is fixedly installed at the output end of the motor 602. A circular block 606 is rotatably mounted on the outer wall of the disc 605. One end of the circular block 606 is rotatably mounted on the outer wall of the disc 605, and the outer wall of the other end of the circular block 606 is in contact with the inner wall of the groove rod 604. A unblocking rod 607 is slidably mounted on the inner wall of the groove rod 604, and the end of the unblocking rod 607 is fixedly mounted on the inner wall of the circular block 606. A connecting rod 608 is slidably mounted on the inner wall of the main body 1. The feed chute 4 is fixedly mounted on the end of the connecting rod 608. The outer wall of the groove rod 604 is fixedly mounted with... There is a pressing rod 609, the outer wall of which is in contact with the outer wall of the connecting rod 608. Two sets of pressing rods 609 are arranged mirror images of each other with the vertical center line of the groove rod 604 as the axis of symmetry. The rotation of the disc 605 causes the circular block 606 to press the inner wall of the groove rod 604, causing the groove rod 604 to slide back and forth on the inner wall of the slide groove 603 as the circular block 606 presses it. While the groove rod 604 slides back and forth, the pressing rod 609 presses the connecting rod 608, causing the connecting rod 608 to slide back and forth. The feed chute 4 at end 08 slides left and right together. While the feed chute 4 slides left and right, the sand inside the feed chute 4 falls evenly onto the screen 3, so that the screen 3 can better screen the sand and avoid the sand from accumulating on the screen 3 and affecting the screening effect of the screen 3. While the disc 605 rotates, the round block 606 will drive the unblocking rod 607 to slide up and down on the inner wall of the trough rod 604 and unblock the feed chute 4 to prevent the feed chute 4 from being blocked and affecting the feeding progress of the feed chute 4.

[0021] The aforementioned auxiliary mechanism 7 includes: a fixed rod 701, a spring 702, a rectangular rod 703, and a flat plate 704. The fixed rod 701 is slidably installed on the inner wall of the main body 1. The spring 702 is fixedly installed on the inner wall of the main body 1. Two sets of fixed rods 701 are arranged symmetrically about the center line in the vertical direction of the main body 1. The inner walls of both sets of fixed rods 701 are fixedly installed with springs 702. One end of the spring 702 is fixedly installed on the inner wall of the main body 1, and the other end of the spring 702 is fixedly installed on the inner wall of the fixed rod 701. The outer wall of the connecting rod 608 is fixedly installed with a rectangular rod 703. A smoothing plate 704 is fixedly installed at the end of the fixed rod 701. While the connecting rod 608 slides left and right, the rectangular rod 703 will press the fixed rod 701 to slide on the inner wall of the main body 1 and drive the smoothing plate 704 to slide along with it. While the fixed rod 701 drives the smoothing plate 704 to slide, the smoothing plate 704 will smooth the sand on the screen 3 and promote the screening effect of the screen 3. When the rectangular rod 703 does not press the fixed rod 701, the spring 702 will push the fixed rod 701 to slide on the inner wall of the main body 1 and drive the smoothing plate 704 to slide along with it and smooth the sand on the screen 3 a second time.

[0022] Working principle: Sand is poured into the feed trough 4. At this time, motor 602 is started, causing its output end to rotate and drive disc 605 to rotate. While disc 605 rotates, round block 606 presses against the inner wall of groove rod 604, causing groove rod 604 to slide back and forth against the inner wall of chute 603. Simultaneously, pressing rod 609 presses against connecting rod 608, causing the feed trough 4 at the end of connecting rod 608 to slide back and forth. As feed trough 4 slides, the sand inside falls evenly onto screen 3, allowing screen 3 to better screen the sand and preventing sand accumulation on screen 3 from affecting its screening effect. As disc 605 rotates... While moving, the round block 606 will drive the unblocking rod 607 to slide up and down on the inner wall of the groove rod 604 and unblock the feed chute 4 to prevent the feed chute 4 from being blocked and affecting the feeding progress of the feed chute 4. While the connecting rod 608 slides left and right, the rectangular rod 703 will squeeze the fixing rod 701 to slide on the inner wall of the main body 1 and drive the smoothing plate 704 to slide along with it. While the fixing rod 701 drives the smoothing plate 704 to slide, the smoothing plate 704 will smooth the sand on the screen 3 and promote the screening effect of the screen 3. When the rectangular rod 703 does not squeeze the fixing rod 701, the spring 702 will push the fixing rod 701 to slide on the inner wall of the main body 1 and drive the smoothing plate 704 to slide along with it and smooth the sand on the screen 3 a second time.

[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
