Description

Technical Field

[0001] This application relates to the technical field of chill installation, and particularly to an adjustable chill fixing tooling. Background Art

[0002] Sand casting refers to a casting method in which castings are produced in sand molds. Due to structural requirements of the castings, the wall thicknesses of various parts are inconsistent. The thicker parts cool more slowly, and the thinner parts cool more quickly. Therefore, shrinkage cavities, shrinkage porosity, or cracking of the thin-walled parts may occur due to uneven cooling rates in different parts of the same casting. To improve the internal quality of the casting, it is necessary to place chills at the positions with larger wall thicknesses of the casting to make all parts of the casting tend to cool simultaneously.

[0003] When installing chill blocks, through holes need to be reserved at the places in the sand mold box where chills are to be placed, and then the chills are inserted from the outside. At the same time, to ensure that the chills do not fall into the cavity along the direction of gravity, steel bars need to be welded on the general chills to form a limiting structure. However, since the sizes of the through holes opened in the core box are different, and the sizes of the chills are continuously worn and reduced during repeated shot peening processes, there may be a certain height difference between the working surface of the chill and the end face of the through hole in contact with the casting after the chill is fixed in the through groove. When the working surface of the chill extends out of the through hole, dimensional problems such as lack of meat in the casting will occur. When the working surface of the chill is recessed inside the through hole, it will cause excess meat in the casting and seriously affect the chilling effect of the chill, ultimately reducing the product quality of the casting, and there are obvious deficiencies. Utility Model Content

[0004] In order to improve the product quality of the casting, this application provides an adjustable chill fixing tooling.

[0005] The adjustable chill fixing tooling provided by this application adopts the following technical solutions:

[0006] An adjustable chill fixing tooling includes a core box. An installation groove is opened in the core box. A chill shell is arranged in the installation groove. The chill shell is fixedly connected to the core box through a fixing component. A receiving groove is opened in the chill shell. An installation block is slidably connected in the receiving groove. A chill block is arranged on the installation block. An adjusting component is arranged on the chill shell. The adjusting component drives the installation block to move along the length direction of the receiving groove.

[0007] By adopting the above technical solution, during installation, the chill block with a chill is placed in the installation groove, and then the chill block is fixed in the installation groove through the fixing component. When there is a height difference between the working surface of the chill and the end face of the installation groove, the worker drives the installation block to move along the length direction of the installation groove through the adjusting component. The movement of the installation block drives the movement of the chill. When the working surface of the chill moves to be flush with the end face of the installation groove close to the casting, the adjustment work ends. Such a setting realizes the adjustment of the position of the chill in the installation groove, thereby reducing the possibility of the working surface of the chill being recessed or protruding from the installation groove and reducing the quality of the casting, and further improving the product quality of the casting.

[0008] Optionally, adjusting grooves and guiding grooves are respectively formed at opposite ends of the inner side wall of the accommodating groove. The length directions of the adjusting grooves and the guiding grooves are parallel to the length direction of the accommodating groove. The adjusting component includes a screw rod rotatably connected in the adjusting groove. An adjusting block is threadedly connected to the screw rod. A guiding block is slidably connected in the guiding groove. The adjusting block and the guiding block are respectively arranged at two ends of the installation block. One end of the screw rod penetrates through the side wall of the chill block and is fixedly connected with a handle.

[0009] By adopting the above technical solution, when the chill protrudes from the installation groove, the worker rotates the handle forward to make the screw rod rotate. Under the guiding and restricting action of the guiding groove and the guiding block, the rotation of the screw rod drives the adjusting block to move. The adjusting block drives the chill to move towards the direction close to the handle through the installation block. When the working surface of the chill retracts to be flush with the end face of the installation groove, stop rotating the screw rod; when the chill is recessed in the installation groove, the worker rotates the handle in the reverse direction to make the screw rod rotate. The reverse rotation of the screw rod drives the installation block to move away from the handle. When the working surface of the chill extends to be flush with the end face of the installation groove, stop rotating the screw rod. Such a setting facilitates the worker to precisely adjust the working surface of the chill and improves the convenience of the worker's operation.

[0010] Optionally, limiting blocks are arranged at one ends of the adjusting grooves and the guiding grooves away from the handle.

[0011] By adopting the above technical solution, the setting of the limiting blocks limits the moving distance of the installation block, avoids the occurrence of the phenomenon that the installation block detaches from the inside of the chill block due to the worker rotating the handle excessively, and ensures the smooth progress of the adjustment work of the adjusting component.

[0012] Optionally, a slot is formed in the installation block. The end of the chill block is slidably arranged in the slot. A connecting component is arranged in the slot. The chill block is detachably connected to the installation block through the connecting component.

[0013] By adopting the above technical solution, when the chill block is damaged, deformed or cracked due to multiple uses, the worker removes the damaged chill block from under the mounting block through the connecting component, and installs a new chill block on the mounting block through the connecting component. The setting of the connecting component facilitates the worker to replace the damaged chill block in time, avoids the possibility of the quality reduction of the casting product caused by the continued use of the damaged chill block, and further improves the product quality of the casting.

[0014] Optionally, the connecting component includes a clamping block arranged on the chill block, a sliding groove which is slidably matched with the clamping block is arranged on the inner side wall of the slot, an arc groove communicated with the sliding groove is arranged on the inner peripheral bottom wall of the slot, a spring is arranged on the inner bottom wall of the slot, a pressing plate is arranged at one end of the spring, one end of the pressing plate is inserted into the arc groove and is slidably matched with the arc groove, a clamping groove for the clamping block to be inserted is arranged on the side wall of the arc groove, and in the natural state of the spring, the clamping block is pressed by the pressing plate in the clamping groove.

[0015] By adopting the above technical solution, when it is necessary to install the chill block, the worker inserts the chill block and the clamping block into the slot and the sliding groove. When the bottom surface of the chill block contacts the surface of the pressing plate, the worker presses the chill block towards the bottom of the slot. At this time, the spring is compressed, the clamping block moves from the sliding groove to the arc groove, rotates the chill block to make the clamping block slide from the arc groove to the communicating place with the clamping groove, and then cancels the acting force on the chill block. The spring resets to drive the pressing plate to reset, and the pressing plate pushes the clamping block into the clamping groove. The chill block is fixed on the mounting block under the clamping fit of the clamping block and the clamping groove. Such a setting can realize the quick disassembly between the chill block and the mounting block only by simple pressing and rotating operations, and improves the convenience of the worker's operation.

[0016] Optionally, the fixing component includes two connecting ear plates, the two connecting ear plates are respectively arranged at opposite ends of the chill block shell, and the connecting ear plates are detachably connected to the core box through connecting bolts.

[0017] By adopting the above technical solution, after placing the chill block shell in the installation groove, the worker installs the connecting bolts on the connecting ear plates and the core box, so as to realize the fixing of the chill block shell in the installation groove, avoid the chill block shell from falling into the cavity due to its own weight, and at the same time, when the adjusting component in the chill block shell is damaged, the worker removes the connecting bolts and takes out the chill block shell from the installation groove, and then installs the chill block shell in the installation groove after overhaul or replacement.

[0018] Optionally, a mounting plate is arranged on the outer surface of the chill block shell, pin holes communicated with each other are arranged on the mounting plate and the handle, a pin rod is slidably connected in the pin holes, and locking nuts are threadedly connected to both ends of the pin rod.

[0019] By adopting the above technical solution, after the working surface of the chill is flush with the end face of the installation groove, the worker inserts the pin rod into the two pin holes and fixes the pin rod with a locking nut to prevent it from coming out. Such a setting realizes the locking of the rotation of the screw rod, reduces the possibility of the worker accidentally touching the screw rod and causing it to rotate during subsequent operations, thereby realizing the fixation of the working surface position of the chill and further improving the product quality of the casting.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. By setting the adjusting assembly in the present application, the adjusting assembly adjusts the working surface of the chill block to be flush with the end face of the installation groove close to the casting, thereby reducing the possibility of the working surface of the chill being recessed or protruding from the installation groove and reducing the quality of the casting, and further improving the product quality of the casting;

[0022] 2. By setting the connecting assembly in the present application, the setting of the connecting assembly facilitates the worker to replace the damaged chill in time, avoids the possibility of the casting product quality being reduced due to the continued use of the damaged chill, and further improves the product quality of the casting.

Detailed Description of the Embodiment

[0028] The following further describes the present application in detail with reference to the attached Figures 1-4 drawings.

[0029] The embodiment of the present application discloses an adjustable chill fixing tooling.

[0030] Reference Figure 1 , an adjustable chill fixing tooling includes a core box 01. A plurality of mounting grooves 011 are formed in the core box 01. In this embodiment, the number of the mounting grooves 011 is three. The opening positions of the three mounting grooves 011 correspond to the positions where the chills 5 need to be placed on the casting. A chill shell 1 is arranged in the mounting groove 011. The chill shell 1 is fixedly connected to the core box 01 through a fixing component 2. The fixing component 2 includes connecting ear plates 21 fixedly connected to opposite sides of the chill shell 1. The bottom surface of the connecting ear plate 21 abuts against the surface of the core box 01. The connecting ear plate 21 is detachably connected to the core box 01 through a connecting bolt 22.

[0031] Reference Figure 1 and Figure 2 , a receiving groove 3 is formed in each chill shell 1. The length direction of the receiving groove 3 is parallel to the length direction of the mounting groove 011. An installation block 4 is slidably connected in each receiving groove 3. A chill 5 is arranged on the surface of the installation block 4 facing the casting. An adjusting component 6 is arranged on the chill shell 1. The adjusting component 6 drives the installation block 4 to move along the length direction of the receiving groove 3. A hanging sand layer is bonded to the working surface of the chill 5 through an adhesive. The hanging sand layer effectively avoids the direct adhesion between the casting and the chill 5 during the solidification process of the casting, reduces the surface damage and defects of the casting caused by adhesion, and improves the product quality of the casting.

[0032] During installation, the worker passes the chill shell 1 with the chill 5 through the mounting groove 011 from top to bottom. Under the lapping of the connecting ear plate 21, the chill shell 1 is placed in the mounting groove 011. Subsequently, the worker connects the connecting ear plate 21 and the core box 01 through the connecting bolt 22. At this time, the chill shell 1 is fixed in the mounting groove 011. When there is a height difference between the working surface of the chill 5 and the end face of the mounting groove 011 close to the casting, the worker drives the installation block 4 to move along the length direction of the mounting groove 011 through the adjusting component 6. The movement of the installation block 4 drives the movement of the chill 5. When the working surface of the chill 5 moves to be flush with the end face of the mounting groove 011, the installation work of the chill 5 ends. The setting of the adjusting component 6 realizes the adjustment of the position of the chill 5 in the mounting groove 011, thereby reducing the possibility that the working surface of the chill 5 is recessed or protrudes from the mounting groove 011 and reducing the quality of the casting, and further improving the product quality of the casting.

[0033] Reference Figure 1 and Figure 2, adjustment grooves 31 and guide grooves 32 are respectively formed at opposite ends of the inner side wall of the accommodation groove 3. The length directions of the adjustment groove 31 and the guide groove 32 are parallel to the length direction of the accommodation groove 3. The adjustment assembly 6 includes a screw rod 61 rotatably connected in the adjustment groove 31. One end of the screw rod 61 penetrates through the top wall of the chill mold shell 1 and is fixedly connected with a handle 62. An adjustment block 63 is threadedly connected to the screw rod 61. A guide block 64 is slidably connected in the guide groove 32. The adjustment block 63 and the guide block 64 are respectively fixedly connected to both ends of the mounting block 4. Limiting blocks 33 are integrally formed on the side walls of the adjustment groove 31 and the guide groove 32 away from the handle 62. The limiting blocks 33 limit the maximum moving distance of the mounting block 4 to reduce the possibility of the mounting block 4 disengaging from the accommodation groove 3 during the adjustment process.

[0034] When the chill block 5 extends out of the installation groove 011, the worker rotates the handle 62 clockwise to make the screw rod 61 rotate. Under the guiding and limiting of the guide groove 32 and the guide block 64, the rotation of the screw rod 61 drives the adjustment block 63 to move. The adjustment block 63 drives the chill block 5 to move towards the direction close to the handle 62 through the mounting block 4. When the working surface of the chill block 5 retracts to be flush with the end surface of the installation groove 011, stop rotating the screw rod 61; when the chill block 5 is retracted into the installation groove 011, the worker rotates the handle 62 counterclockwise to make the screw rod 61 rotate. The reverse rotation of the screw rod 61 drives the mounting block 4 to move away from the handle 62. When the working surface of the chill block 5 extends to be flush with the end surface of the installation groove 011, stop rotating the screw rod 61. Such a setting facilitates the worker to precisely adjust the working surface of the chill block 5 and improves the convenience of the worker's operation.

[0035] Refer to Figure 2 and Figure 3 , a mounting plate 7 is fixedly connected to the outer surface of the chill mold shell 1. The mounting plate 7 is vertically arranged on the surface of the chill mold shell 1. Plug holes 71 communicating with each other are formed at the rotating shaft of the mounting plate 7 and the handle 62. A plug rod 72 is slidably connected in the plug holes 71. Locking nuts 73 are threadedly connected to both ends of the plug rod 72.

[0036] After the working surface of the chill block 5 is flush with the end surface of the installation groove 011, the worker inserts the plug rod 72 into the two plug holes 71 and fixes the plug rod 72 with the locking nuts 73 to prevent it from coming out. Such a setting realizes the locking of the rotation of the screw rod 61, reduces the possibility of the worker accidentally touching and causing the screw rod 61 to rotate in subsequent operations, thereby realizing the fixation of the position of the working surface of the chill block 5 and further improving the product quality of the casting.

[0037] Refer to Figure 2 and Figure 4, during the casting process, the chill block 5 will be subjected to thermal shock from the high-temperature molten metal. As the number of uses of the chill block 5 increases, the surface of the chill block 5 may experience wear, deformation, shrinkage, etc. due to thermal shock. At this time, if the worn chill block 5 is continued to be used, the product quality of the casting will be reduced.

[0038] To solve the above problems, a slot 8 is provided at one end of the mounting block 4 facing the chill block 5. The end of the chill block 5 facing the mounting block 4 is slidably connected in the slot 8. A connecting component 9 is arranged inside the slot 8. The chill block 5 is detachably connected to the mounting block 4 through the connecting component 9.

[0039] When the chill block 5 is damaged, deformed, cracked, etc. due to multiple uses, the worker removes the damaged chill block 5 from under the mounting block 4 through the connecting component 9, and installs a new chill block 5 on the mounting block 4 through the connecting component 9. The setting of the connecting component 9 facilitates the worker to replace the damaged chill block 5 in time, avoiding the possibility of reducing the product quality of the casting due to the continued use of the damaged chill block 5, and further improving the product quality of the casting.

[0040] Refer to Figure 2 and Figure 4 , the connecting component 9 includes two clamping blocks 91 fixedly connected to one end of the chill block 5 close to the mounting block 4. The two clamping blocks 91 are arranged oppositely on both sides of the chill block 5. Sliding grooves 81 for the two clamping blocks 91 to slide are provided on the opposite inner side walls of the slot 8. Arc grooves 82 corresponding to and communicating with the two sliding grooves 81 are provided on the inner peripheral side wall of the slot 8. A spring 92 is arranged on the inner bottom wall of the slot 8. One end of the spring 92 is fixedly connected to the inner bottom wall of the slot 8, and the other end is fixedly connected to a pressing plate 93. The pressing plate 93 includes an integrally formed circular bottom plate and two arc-shaped insertion plates. The arc-shaped insertion plates are inserted into the corresponding arc grooves 82 and are slidably matched with the arc grooves 82. Clamping grooves 83 for clamping and cooperating with the two clamping blocks 91 are provided on the inner side walls of the two arc grooves 82. The center of the clamping groove 83 and the center of the sliding groove 81 are not on the same straight line. In the natural state of the spring 92, the two clamping blocks 91 are pressed tightly in the clamping groove 83 by the pressing plate 93.

[0041] When it is necessary to disassemble the worn chill block 5, the worker presses the chill block 5 towards the mounting block 4. At this time, the spring 92 is compressed, and the clamping block 91 moves from the clamping groove 83 into the arc groove 82. The worker rotates the chill block 5 in the reverse direction to make the clamping block 91 slide in the arc groove 82 to the communication position between the arc groove 82 and the sliding groove 81. Then, the force on the chill block 5 is cancelled, and the spring 92 resets to push the clamping block 91 to slide from the arc groove 82 into the sliding groove 81. The worker pulls out the chill block 5 from the slot 8. Then, the worker inserts the new chill block 5 and the clamping block 91 into the slot 8 and the sliding groove 81. When the bottom surface of the chill block 5 contacts the surface of the abutting plate 93, the worker presses the chill block 5 towards the bottom of the slot 8. At this time, the spring 92 is compressed, and the clamping block 91 transfers from the sliding groove 81 to the arc groove 82. Rotate the chill block 5 in the forward direction to make the clamping block 91 slide from the arc groove 82 to the communication position with the clamping groove 83. Then, the force on the chill block 5 is cancelled, and the spring 92 resets to drive the abutting plate 93 to reset. The abutting plate 93 pushes the clamping block 91 into the clamping groove 83. The chill block 5 is fixed on the mounting block 4 under the clamping cooperation of the clamping block 91 and the clamping groove 83. With such a setting, only simple pressing and rotating operations are required to achieve the quick disassembly between the chill block 5 and the mounting block 4, improving the convenience of the worker's operation.

[0042] The implementation principle of an adjustable chill fixing tooling in an embodiment of the present application is as follows: During installation, the worker passes the chill shell 1 with the chill block 5 through the installation groove 011 from top to bottom. Under the lapping of the connecting ear plate 21, the chill shell 1 is placed in the installation groove 011. Then, the worker connects the connecting ear plate 21 and the core box 01 through the connecting bolt 22. At this time, the chill shell 1 is fixed in the installation groove 011. When there is a height difference between the working surface of the chill block 5 and the end face of the installation groove 011 close to the casting, the worker rotates the handle 62. The handle 62 drives the screw rod 61 to rotate. Under the guiding restriction of the guiding groove 32 and the guiding block 64, the rotation of the screw rod 61 drives the adjusting block 63 to move. The adjusting block 63 drives the chill block 5 to move towards the direction close to the end face of the installation groove 011 through the mounting block 4. When the working surface of the chill block 5 moves to be flush with the end face of the installation groove 011, the worker inserts the pin rod 72 into the two pin holes 71 and fixes the pin rod 72 with the locking nut 73 to prevent it from coming out. The installation work of the chill is completed. With such a setting, the position adjustment of the chill block 5 in the installation groove 011 is realized, thereby reducing the possibility that the working surface of the chill block 5 is recessed or protruded from the installation groove 011 to reduce the quality of the casting, and thus improving the product quality of the casting.

[0043] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
