Detailed Implementation

[0029] 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.

[0030] Reference Figure 1 , Figure 2 , Figure 3 This utility model provides an embodiment of an engine cylinder block casting core support, comprising a mounting sleeve 1 for mounting other components. A connecting rod 4 for connecting a support seat 2 is slidably connected to the inner wall of the mounting sleeve 1. One end of the connecting rod 4 is fixedly connected to a support seat 2 for supporting the sand core, and the other end of the connecting rod 4 is fixedly connected to a threaded rod 5 for adjusting the spacing between the support seats 2. The spacing between the support seats 2 can be adjusted by rotating the threaded rod 5. Sliding rods 7 are slidably connected to the inner walls of both the connecting rod 4 and the threaded rod 5, and the sliding rods 7 are used to restrict the connecting rod 4 and the threaded rod 5. An adjustment mechanism is provided in the middle of the mounting sleeve 1, and the adjustment mechanism includes a limiting component 6. The limiting component 6 includes a push block 61 for pushing the clamping block 62 to move. The push block 61 is slidably connected to the inner wall of the mounting sleeve 1. The end of the push block 61 near the center line of the mounting sleeve 1 is fixedly connected to a clamping block 62 for limiting the rotation of the sliding rod 7. The side of the clamping block 62 away from the push block 61 is fixedly connected to a sliding block 63 for driving the edge of the clamping block 62 to retract. The sliding block 63 drives the clamping block 62 to retract its edge, which can more tightly limit the sliding rod 7. The side of the sliding block 63 away from the clamping block 62 is provided with a connecting block 64 for connecting the push block 63. The outer surface of the connecting block 64 near the sliding block 63 is provided with a sliding groove 65 for limiting the movement of the sliding block 63.

[0031] Reference Figure 1 , Figure 4 The adjustment mechanism also includes an auxiliary component 3 for assisting the movement of the limiting component 6 inside the mounting sleeve 1. The auxiliary component 3 includes a rotating sleeve 31 for driving the extrusion block 33 to move. The rotating sleeve 31 is sleeved on the outer wall of the mounting sleeve 1. By rotating the rotating sleeve 31, the extrusion block 33 can be selected to push the push block 61 or the connecting block 64. Both ends of the rotating sleeve 31 are fixedly connected to the breaking block 36. The operator can pull the connecting belt 32 to break the breaking block 36, remove the disassembly block 35 from the rotating sleeve 31, thereby removing the auxiliary component 3 from the outer wall of the mounting sleeve 1 to avoid affecting the use of the device. The breaking block 36 is away from the rotating sleeve 31. One end of the sleeve 31 is fixedly connected to a disassembly block 35 for installing the connecting band 32. The outer wall of the disassembly block 35 is fixedly connected to a connecting band 32 for installing the extrusion block 33. The end of the connecting band 32 away from the disassembly block 35 is fixedly connected to an extrusion block 33 for extruding and pushing the pusher block 61 and the connecting block 64. The end of the extrusion block 33 away from the center line of the mounting sleeve 1 is fixedly connected to a pressing plate 34 for easy use by the staff. The rotating sleeve 31 is C-shaped to facilitate the removal of the rotating sleeve 31. After the adjustment is completed, the auxiliary component 3 can be directly removed from the outer wall of the mounting sleeve 1 to avoid affecting its use during casting.

[0032] Reference Figure 2 , Figure 3The connecting block 64 is slidably connected to the inner wall of the mounting sleeve 1, and the sliding rod 7 is rotatably connected to the inner wall of the mounting sleeve 1. The sliding rod 7 rotates along with the support seat 2 when it is rotated for adjustment. When the limiting component 6 restricts the rotation of the sliding rod 7, the sliding rod 7 can prevent the support seat 2 from accidentally rotating, ensuring the accuracy of the adjustment. The outer wall of the sliding rod 7 near the middle is provided with friction texture 8 to increase the limiting effect of the clamping block 62. The friction texture 8 is provided on the outer wall of the sliding rod 7 near the middle and is only used in conjunction with the clamping block 62. The clamping block 62 is set as an elastic U-shaped block, which can avoid contact when it leaves the sliding rod 7. Multiple sets of sliding blocks 63 are provided. The sliding blocks 63 are symmetrically arranged with the center line of the clamping block 62 as the axis of symmetry. When the push block 61 pushes the clamping block 62, the sliding block 63 uses the arc surface of the outer wall to make the clamping block 62 move towards the center line of the clamping block 62. The sliding rod 7 is clamped internally. The outer wall of the sliding block 63, away from the center line of the clamping block 62, is set as an arc surface. The threaded rod 5 is installed on the inner wall of the mounting sleeve 1. After the user releases the restriction component 6, the user can rotate the support seat 2 to drive the threaded rod 5 to rotate and adjust the position of the support seat 2. There are multiple sets of threaded rods 5 and connecting rods 4. The multiple sets of threaded rods 5 and connecting rods 4 are symmetrically arranged with the center line of the mounting sleeve 1 as the axis of symmetry. The support seat 2, which can be adjusted up and down, makes the device more flexible in use. The end of the sliding block 63 near the connecting block 64 is provided with a protrusion, which can limit the movement range of the sliding block 63. The protrusion of the connecting block 64 is slidably connected to the inner wall of the sliding groove 65, allowing the sliding block 63 to follow the connecting block 64 into the inner wall of the mounting sleeve 1, so as to realize the adjustment of the clamping block 62 by the sliding block 63.

[0033] Working principle: In use, the operator first releases the rotation restriction on the sliding rod 7. By pressing the squeezing block 33 in the auxiliary component 3, the connecting block 64 is pushed inward along the sliding groove 65, causing the sliding block 63 to disengage from the clamping area of ​​the clamping block 62. At this time, the clamping block 62 returns to a relaxed state due to its own elasticity, releasing the friction constraint on the sliding rod 7. Subsequently, the support seat 2 is manually rotated. Through the meshing action of the threaded rod 5 and the internal thread of the mounting sleeve 1, the connecting rod 4 and the support seat 2 are driven to move axially, realizing the flexible adjustment of the sand core support spacing. Multiple sets of symmetrically arranged threaded rods 5 and connecting rods 4 can be adjusted synchronously to ensure the balance and adaptability of the support seat 2. After adjustment, the squeezing block 33 is pulled out, and the auxiliary component 3 is rotated 180° to allow the squeezing block 33 to push the push block 61, causing it to move under the pushing action of the squeezing block 33, pushing the clamping block 62 to clamp the sliding rod. 7. The U-shaped elastic structure of the clamping block 62 tightens inward under the guidance of the arc surface of the sliding block 63. Its inner side forms a high-friction contact with the friction texture 8 on the outer wall of the sliding rod 7, effectively restricting the rotation of the sliding rod 7. At the same time, the sliding rod 7 restricts the circumferential displacement of the connecting rod 4 and the threaded rod 5 through the axial sliding connection structure, thereby locking the position of the support seat 2 and preventing displacement deviation caused by vibration or external force during the casting process. After adjustment and locking are completed, the operator pulls the connecting belt 32 to disconnect the fracture block 36 and remove the auxiliary component 3 from the outer wall of the mounting sleeve 1 as a whole. The auxiliary component 3 can use inexpensive plastic material to save costs and increase the practicality of the device. The design of the C-shaped rotating sleeve 31 and the easily separable fracture block 36 facilitates quick disassembly, avoids the auxiliary component 3 from affecting the device's performance during casting, and reduces the size of the device, ensuring the simplicity and safety of the casting process.
