Description

Technical Field

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

[0002] Sand cores are materials used to manufacture mold cores in casting production. They play a crucial role in the casting process, and their core function is to form internal cavities, complex structures, or parts that cannot be directly formed by sand molds in castings. They directly determine the internal quality, structural integrity, and dimensional accuracy of castings. The essence of sand cores is a "removable internal mold." While sand molds (outer molds) determine the external shape of castings, sand cores are specifically responsible for "defining internal space" and solving the problem of forming internal structures that sand molds cannot cover. Sand cores are mainly composed of materials such as casting sand, silica sand, thermosetting resin, dispersants, and lubricants, and are mainly used in the automotive manufacturing, aerospace, and machinery equipment industries.

[0003] Currently, after sand cores are processed, they are placed inside a support frame. The support frame serves to hold and protect the sand core, preventing external objects from contacting it and causing damage. The support frame encloses the sand core, maintaining its safety. While existing support frames provide this protection, they are not convenient for stacking. A support frame filled with sand cores is quite heavy, and each support frame occupies a large area. Stacking support frames requires multiple people working together, making it inconvenient to use. Therefore, we provide a sand core support frame for casting that solves these problems.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-5 As shown, this utility model provides a technical solution: a sand core support for casting, including a base frame 1, a frame 2, and a mounting frame 3. A sliding sleeve 4 is fixedly connected to the top of the base frame 1. A sleeve 5 is in contact with the inner wall of the sliding sleeve 4. A first spring 6 is installed inside the sleeve 5. The frame 2 is fixedly installed above the sleeve 5. There are multiple sliding sleeves 4 and sleeves 5. Multiple sliding sleeves 4 and sleeves 5 surround the base frame 1 and the frame 2. The base frame 1 and the frame 2 are supported by the sliding sleeves 4 and sleeves 5, so that the frame 2 has the function of moving up and down. A positioning pin is also installed on the sleeve 5. The positioning pin is located inside the sliding sleeve 4 and is slidably connected to the inner wall of the sliding sleeve 4. The positioning pin prevents the sleeve 5 from detaching from the sliding sleeve 4.

[0028] The mounting frame 3 is located inside the frame 2. There are multiple mounting frames 3, and they are arranged in an equidistant array. The outer surface of the mounting frame 3 is fixedly connected to the slide rail 7, and the inner wall of the frame 2 is fixedly connected to the slide channel 8. The inner wall of the slide channel 8 is slidably connected to the outer surface of the slide rail 7. The slide channel 8 supports the slide rail 7, enabling the slide rail 7 to slide and move. The slide rail 7 transmits the supporting force to the mounting frame 3, enabling the mounting frame 3 to move. By moving the mounting frame 3 to the outside of the frame 2, the mounting frame 3 is positioned outside the frame 2, making it easier to load the sand core inside. After the sand core inside the mounting frame 3 is loaded, the mounting frame 3 is pushed back into the frame 2.

[0029] A shock absorber 10 is fixedly installed on the top of the base frame 1. The output end of the shock absorber 10 is fixedly connected to the lower surface of the frame 2. There are multiple shock absorbers 10, and multiple shock absorbers 10 surround the base frame 1 and the frame 2. The shock absorbers 10 play a shock absorption role on the frame 2 and the mounting frame 3, reducing the damage to the sand core caused by the bumps when the overall bracket moves.

[0030] A guide rod 18 is fixedly connected to the inner bottom wall of the sliding sleeve 4. A first spring 6 is sleeved on the outside of the guide rod 18. One end of the first spring 6 is fixedly connected to the inner bottom wall of the sliding sleeve 4, and the other end of the first spring 6 is fixedly connected to the inner top wall of the sleeve 5. The guide rod 18 provides support for the first spring 6, maintaining the stability of the first spring 6 during elastic contraction. The spring provides elastic support for the frame 2 and the mounting bracket 3, and absorbs the vibration of the frame 2 and the mounting bracket 3, reducing the damage of vibration force to the sand core.

[0031] The mounting frame 3 has a rubber pad 11 inside and a waste discharge hole 12 on its inner side. A handle 13 is fixedly connected to the outer surface of the mounting frame 3. The rubber pad 11 has good elasticity. When the sand core is placed inside the mounting frame 3, the mounting frame 3 contacts the sand core through the rubber pad 11, which plays a role in flexible contact and prevents the sand core from being bumped. The handle 13 makes it easy to apply force to the mounting frame 3, thereby moving the mounting frame 3 to a different position. The waste discharge hole 12 is used to discharge the debris that has fallen from the sand core inside the mounting frame 3.

[0032] A positioning mechanism 9 is provided on the outside of the frame 2 to maintain the stability of the mounting frame 3. The positioning mechanism 9 includes a slide 901, which is fixedly installed on one side of the frame 2. A stop 902 is slidably connected to the inner wall of the slide 901. One side of the stop 902 is in contact with one side of the mounting frame 3. A pull rod 903 is rotatably connected to one end of the stop 902 inside the slide 901. A pull ring 904 is fixedly connected to one end of the pull rod 903 outside the slide 901. The slide 901 provides support for the stop 902 to maintain its stability. The stop 902 acts as a block on the outside of the mounting frame 3 to prevent the mounting frame 3 from moving to the outside of the frame 2.

[0033] A second spring 905 is sleeved on the outside of the pull rod 903. One end of the second spring 905 contacts one side of the stop block 902, and the other end of the second spring 905 contacts the inner wall of the slide block 901. A tube seat 906 is fixedly connected to one side of the slide block 901, and the inner wall of the tube seat 906 contacts the outer surface of the pull rod 903. A groove 907 is formed on the inner side of the tube seat 906, and the inner wall of the groove 907 contacts the outer surface of the pull ring 904. A retaining groove 908 is formed on the inner side of the tube seat 906, and the retaining groove 908 is adapted to the pull ring 904. The second spring 905 provides an elastic pushing force to the stop block 902, pushing the stop block 902 to move outward from the slide block 901. The stop block 902 is kept in contact with one side of the mounting frame 3. The stop block 902 can be moved by the pull rod 903 and the pull ring 904. The slide groove 907 provides space for the pull ring 904 to move. The stop groove 908 provides positioning for the pull ring 904. After the pull ring 904 moves the stop block 902 into the slide block 901 by the pull rod 903, the pull ring 904 is rotated to align with the stop groove 908. Then the pull ring 904 is placed into the stop groove 908 to restrict the movement of the pull ring 904. The stop groove 908 supports the pull ring 904, so that the stop block 902 is in a position inside the slide block 901 that is no longer in contact with the mounting frame 3.

[0034] A support leg 14 is fixedly installed at the bottom of the base frame 1. A fork hole 15 is opened on the inner side of the support leg 14. A top plate 16 is fixedly connected to the top of the frame 2. A positioning groove 17 is opened on the inner side of the top plate 16, and the positioning groove 17 is adapted to the support leg 14. A support platform is formed by the top plate 16. When it is necessary to stack the brackets, the brackets are raised and then the support leg 14 is placed into the positioning groove 17. The positioning groove 17 restricts the movement of the support leg 14, maintains the stability between the brackets, and provides support force for the brackets. The support leg 14 provides space for the forklift's feet to pass through the fork hole 15 inside the support leg 14.

[0035] Working principle: In use, the pull ring 904 first moves the pull rod 903 and the stop block 902, causing the stop block 902 to disengage from the mounting frame 3, thus removing the obstruction to the mounting frame 3. After moving, the stop block 902 enters the interior of the slide block 901. Simultaneously, the second spring 905 is compressed. Then, the pull ring 904 is rotated to align it with the retaining groove 908. The pull ring 904 is then inserted into the retaining groove 908. Finally, the mounting frame 3 is pulled out from inside the frame 2 using the handle 13. Place the sand core into the inside of the mounting frame 3. After the first layer of the mounting frame 3 is filled with sand cores, push the mounting frame 3 into the inside of the frame 2. Then, remove the pull ring 904 from the inside of the retaining groove 908 and rotate the pull ring 904 in the opposite direction to align the pull ring 904 with the slide groove 907. Then release the pull ring 904. The second spring 905 pushes the stop block 902 to move outward of the slide block 901. Then the stop block 902 contacts the mounting frame 3 and acts as a block outside the mounting frame 3, limiting the movement of the mounting frame 3 and maintaining the stability of the mounting frame 3.
