Description

Technical Field

[0001] This invention relates to the field of automobile engine die-cast cylinder block manufacturing, and in particular to a quick-change core loading and unloading tool. Background Technology

[0002] In the existing technology, quick-change cores are widely used in cylinder block die casting molds. Quick-change cores are used to form holes and openings in the cylinder block. Because quick-change cores have a relatively short lifespan, they need to be disassembled and replaced frequently. However, the loading and unloading of existing quick-change cores requires more than four types of quick-change core loading and unloading tools, which makes the loading and unloading steps of quick-change cores more complicated and the loading and unloading speed of quick-change cores relatively slow, resulting in low loading and unloading efficiency of quick-change cores. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a quick-change core loading and unloading tool that improves the ease of operation for personnel, simplifies the loading and unloading steps, reduces loading and unloading time, and increases loading and unloading speed, thereby improving the loading and unloading efficiency of quick-change cores.

[0004] According to a first aspect of the present invention, a quick-change core loading and unloading tool includes: a tool body extending along a first direction, one end of which has a mounting groove recessed into the tool body along the first direction for assembling a quick-change core; a striking block and a limiting structure, both the striking block and the limiting structure being sleeved on the tool body and spaced apart along the first direction, with the striking block located on the side of the limiting structure closer to the mounting groove, and both the striking block and the limiting structure being fixed to the tool body; and an impact portion sleeved on the tool body and located between the striking block and the limiting structure, the impact portion being movable relative to the tool body along the first direction, and along the first direction, the impact portion being disposed opposite to both the striking block and the limiting structure, and the impact portion being capable of driving the tool body to rotate around the first direction.

[0005] According to the first aspect of the present invention, the quick-change core loading and unloading tool, compared with the traditional quick-change core loading and unloading which requires the operation of multiple quick-change core loading and unloading tools, is advantageous in reducing the steps of personnel operating the quick-change core loading and unloading tool, improving the convenience of personnel operating the quick-change core loading and unloading tool, simplifying the quick-change core loading and unloading steps, reducing the quick-change core loading and unloading time, and increasing the quick-change core loading and unloading speed, thereby improving the loading and unloading efficiency of quick-change cores.

[0006] In some examples of the present invention, the mounting groove is constructed as a tapered groove.

[0007] In some examples of the present invention, the tool body is formed with an exhaust hole communicating with the mounting groove.

[0008] In some examples of the present invention, the tool body has a guide segment extending along a first direction, the guide segment and the impact block being adjacent along the first direction, the cross-section of the guide segment being polygonal, the impact portion having a mounting through hole extending through the impact portion along the first direction, the guide segment passing through the mounting through hole, the cross-section of the mounting through hole being polygonal, and the cross-sectional shape of the guide segment being the same as the cross-sectional shape of the mounting through hole.

[0009] In some examples of the present invention, the guide segment is formed with a first guide structure, and the impact portion is formed with a second guide structure. The first guide structure and the second guide structure cooperate to guide the impact portion in a first direction.

[0010] In some examples of the present invention, the tool body further includes a mounting section, which is located on the side of the guide section away from the impact block and connected to the guide section along a first direction, and a limiting structure is assembled to the mounting section.

[0011] In some examples of the present invention, the outer peripheral wall of the limiting structure is formed with multiple disassembly and assembly planes, which are arranged sequentially along the circumference of the limiting structure.

[0012] In some examples of the present invention, the limiting structure is detachably provided in the mounting section.

[0013] In some examples of the present invention, the outer peripheral wall of the tool body is formed with an external thread, the limiting structure is annular to form a threaded hole, the limiting structure is sleeved on the part of the tool body with the external thread, and the external thread and the internal thread of the threaded hole are engaged and connected.

[0014] In some examples of the present invention, the impact block and the tool body are integrally formed.

[0015] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0018] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] The following is for reference. Figures 1-3 This invention describes a quick-change core loading and unloading tool 100 according to an embodiment of the present invention. The quick-change core loading and unloading tool 100 is a special-purpose tool used for installing and removing quick-change cores 300 on a cylinder block die-casting mold 800. The quick-change core 300 in this application is configured as a threaded quick-change core 300 with a tapered portion.

[0020] like Figure 1 , Figure 2 As shown, according to a first aspect embodiment of the present invention, a quick-change core loading and unloading tool 100 includes: a tool body 200 extending along a first direction, one end of which has a mounting groove 210 recessed inward along the first direction for assembling a quick-change core 300; a stop block 400 and a limiting structure 500, both of which are sleeved on the tool body 200 and spaced apart along the first direction. 400 is located on the side of the limiting structure 500 near the mounting groove 210. Both the impact block 400 and the limiting structure 500 are fixed to the tool body 200. The impact part 600 is sleeved on the tool body 200 and located between the impact block 400 and the limiting structure 500. The impact part 600 is movable relative to the tool body 200 along the first direction. Along the first direction, the impact part 600 is arranged opposite to both the impact block 400 and the limiting structure 500, and the impact part 600 can drive the tool body 200 to rotate around the first direction.

[0021] The tool body 200 can be manufactured using FDAC mold steel. The mounting groove 210 can be constructed as a conical groove or a polygonal groove. The mounting groove 210 can be formed by milling, stamping, or other methods, and can be constructed as a smooth, recessed structure. The impact block 400 can be manufactured using FDAC mold steel. The impact block 400 can be fixed to the tool body 200 by welding, snap-fitting, bolting, or other methods, or it can be integrally formed with the tool body 200. The limiting structure 500 can be formed by turning, injection molding, or other methods. The limiting structure 500 can be a hexagonal nut or a round nut. The limiting structure 500 can be fixed to the tool body 200 by threaded engagement or by welding. The impact part 600 can be made of materials such as 45# steel or 45Cr alloy steel. The impact part 600 can be formed by turning, milling, or other methods, and can undergo 45# / 40Cr heat treatment. As an embodiment, the impact part 600 can be provided with a through hole extending through it along a first direction. The through hole can be constructed as a flat hole, and the tool body 20 passes through the through hole. The outer peripheral wall of the impact part 600 can be provided with a knurled structure. The knurled structure helps to increase the friction force when the operator operates the quick-change core loading and unloading tool 100, thereby improving the operational stability of the quick-change core loading and unloading tool 100. The first direction is the length direction of the tool body 200. In this application, the first direction is... Figure 1 The Z direction is shown.

[0022] When it is necessary to install the quick-change core 300 into the cylinder die-casting mold 800, the quick-change core 300 can be aligned with the mounting groove 210 of the tool body 200, and the quick-change core 300 can be inserted into the mounting groove 210 in the first direction (if the temperature is too high or other conditions prevent the quick-change core 300 from being held, the quick-change core 300 can be pre-installed into the mounting groove 210), which helps to make the inner sidewall of the mounting groove 210 fit with the quick-change core 300. Personnel push the impact part 600 towards the impact block 400, causing the impact part 600 to... The impact part 600 moves towards the impact block 400 in the first direction, causing the impact part 600 to impact the impact block 400. The impact of the impact part 600 on the impact block 400 can generate a first impact force. The first impact force can be transmitted to the tool body 200 through the impact block 400, causing the quick-change core 300 to be inserted into the mounting groove 210, thereby making the quick-change core 300 in close contact with the inner wall of the mounting groove 210. This is beneficial for the mounting groove 210 and the quick-change core 300 to fit together further. The close contact between the quick-change core 300 and the inner wall of the mounting groove 210 will generate friction. Then, the impact part 600 is rotated around the first direction. The impact part 600 can drive the tool body 200 to rotate around the first direction. The friction force can be converted into torque, which is beneficial to make the tool body 200 drive the quick-change core 300 to rotate synchronously around the first direction until the threaded part of the quick-change core 300 is completely screwed into the cylinder die-casting mold 800 and tightened. The personnel can push the impact part 600 to move towards the limiting structure 500 along the first direction, so that the impact part 600 impacts the limiting structure 500. The impact part 600 impacting the limiting structure 500 can generate a second impact force. The second impact force can pull the quick-change core 300 out of the mounting groove 210 of the tool body 200, thereby separating the tool body 200 from the quick-change core 300. Then, the quick-change core loading and unloading tool 100 is removed to complete the assembly of the quick-change core 300.

[0023] When it is necessary to remove the quick-change core 300 from the cylinder die-casting mold 800, the mounting slot 210 of the tool body 200 can be aligned with the quick-change core 300 on the cylinder die-casting mold 800. The quick-change core 300 can be inserted into the mounting slot 210 along the first direction. The quick-change core 300 and the inner wall of the mounting slot 210 will be in close contact, generating friction. A person can push the impact part 600 to move towards the impact block 400 along the first direction and impact the impact block 400. The impact of the impact part 600 on the impact block 400 can generate a first impact force. The first impact force can insert the quick-change core 300 into the mounting slot 210, so that the inner wall of the mounting slot 210 is in close contact with the quick-change core 300. A person can rotate the impact part 600 around the first direction. The impact part 600 can drive the tool body 200 to rotate around the first direction. The friction can be converted into torque, which is beneficial for the tool body 200 to drive the quick-change core 300. The tool rotates synchronously in the first direction, causing the threaded portion of the quick-change core 300 to gradually unscrew from the cylinder die-casting mold 800. Personnel can push the impact part 600 along the first direction towards the limiting structure 500 and impact it. The impact of the impact part 600 against the limiting structure 500 generates a second impact force, which separates the cylinder die-casting mold 800 from the quick-change core 300. Then, the tool body 200 lifts the quick-change core 300 and removes it from the cylinder die-casting mold 800, completing the disassembly of the quick-change core 300. If it is necessary to remove the quick-change core 300 separately, it can be removed from the mounting slot 210.

[0024] The limiting structure 500 facilitates the impact of the impact part 600, facilitates the separation of the tool body 200 from the quick-change core 300, and also facilitates the removal of the quick-change core 300 from the cylinder die-casting mold 800. The impact block 400 facilitates the impact of the impact part 600, facilitates the insertion of the quick-change core 300 into the mounting groove 210, increases the insertion depth of the quick-change core 300 into the mounting groove 210, thereby facilitating the fit between the inner wall of the mounting groove 210 and the quick-change core 300, and facilitating the generation of friction between the tool body 200 and the quick-change core 300. This friction can be converted into torque, which helps the tool body 200 drive the quick-change core 300 to rotate synchronously around the first direction. This allows personnel to complete the loading and unloading of the quick-change core 300 with less force, and improves the convenience of personnel operating the quick-change core loading and unloading tool 100. Compared to the traditional quick-change core 300, which requires the operation of multiple quick-change core loading and unloading tools 100, the quick-change core loading and unloading tool 100 of this application helps reduce the steps required for personnel to operate the quick-change core 300, further improving the convenience of personnel operation of the quick-change core loading and unloading tool 100 and simplifying the loading and unloading steps of the quick-change core 300. The traditional method of loading and unloading the quick-change core 300 takes more than 2 minutes, while the quick-change core loading and unloading tool 100 of this application can shorten the loading and unloading time of the quick-change core 300 to within 30 seconds, improving efficiency by more than 3 times. This helps reduce the loading and unloading time of the quick-change core 300, increases the loading and unloading speed of the quick-change core 300, and thus improves the loading and unloading efficiency of the quick-change core 300.

[0025] According to some embodiments of the present invention, such as Figure 2 , Figure 3 As shown, the mounting groove 210 is constructed as a conical groove.

[0026] The inner wall of the tapered groove is inclined, which can match the tapered structure of the quick-change core 300. When the impact part 600 impacts the impact block 400, the inclined inner wall of the tapered groove can guide the quick-change core 300 to be accurately embedded into the mounting groove 210 in the first direction. This is beneficial for the quick-change core 300 to fit tightly with the inner wall of the mounting groove 210, and also for limiting the quick-change core 300, which helps to reduce the risk of the quick-change core 300 shaking during the loading and unloading process. The tapered groove can be aligned with the tapered angle of the quick-change core 300. The length of the quick-change core 300 inserted into the mounting groove 210 can be greater than 2 / 3 of the total length of the quick-change core 300. This is beneficial for increasing the contact area between the tool body 200 and the quick-change core 300, increasing the friction between them, and allowing personnel to load and unload the quick-change core 300 with less force. This further improves the ease of operation for personnel using the quick-change core loading and unloading tool 100.

[0027] According to some embodiments of the present invention, such as Figure 1 , Figure 2 , Figure 3 As shown, the tool body 200 has an exhaust hole 700 that communicates with the mounting groove 210.

[0028] The vent 700 can be constructed in shapes such as circular or rectangular, and can be formed by drilling, milling, or other methods. The vent 700 can be formed on the side wall of the mounting groove 210. During assembly, the quick-change core 300 needs to be embedded into the mounting groove 210 of the tool body 200. If the tool body 200 does not have a vent 700, the quick-change core 300 will compress the air within the mounting groove 210 during insertion, creating an air resistance. This air resistance will prevent the quick-change core 300 from being inserted into the mounting groove 210, resulting in an assembly gap between the quick-change core 300 and the inner wall of the mounting groove 210, thus preventing a tight fit between the quick-change core 300 and the mounting groove 210. This application provides an exhaust hole 700 on the tool body 200 that communicates with the mounting groove 210. This allows the exhaust hole 700 to promptly expel air from the mounting groove 210 during the assembly of the quick-change core 300, reducing air resistance and hindering the insertion of the quick-change core 300 into the mounting groove 210. This further facilitates a tight fit between the quick-change core 300 and the mounting groove 210. During the installation and removal of the quick-change core 300, debris, dust, and other impurities may remain in the mounting groove 210. The exhaust hole 700 on the tool body 200, communicating with the mounting groove 210, allows some of these impurities to be expelled with the air. This reduces the amount of impurities in the mounting groove 210, lowers the risk of wear on the quick-change core 300 due to impurities, extends the service life of the quick-change core 300, and reduces maintenance costs.

[0029] According to some embodiments of the present invention, such as Figure 1 , Figure 2 , Figure 3 As shown, the tool body 200 has a guide section 220 extending along a first direction. Along the first direction, the guide section 220 is adjacent to the impact block 400. The cross-section of the guide section 220 is polygonal. The impact part 600 has a mounting through hole 610 extending through the impact part 600 along the first direction. The guide section 220 passes through the mounting through hole 610. The cross-section of the mounting through hole 610 is polygonal. The cross-sectional shape of the guide section 220 is the same as the cross-sectional shape of the mounting through hole 610.

[0030] The cross-section of the guide section 220 can be constructed into a polygonal shape such as a triangle or rectangle, and the cross-section of the mounting through hole 610 can also be constructed into a polygonal shape such as a triangle or rectangle. When the impact part 600 is rotated by personnel, the polygonal cross-sections of the guide section 220 and the mounting through hole 610 fit together, which helps reduce the risk of relative slippage between the impact part 600 and the guide section 220, and improves the reliability of loading and unloading the quick-change core 300. The cross-sectional shape of the guide section 220 is the same as that of the mounting through hole 610, which helps to ensure the coaxiality of the rotation of the impact part 600 and the guide section 220, which helps to reduce the risk of wear of the impact part 600 and the guide section 220 due to low coaxiality of rotation, which helps to increase the service life of the quick-change core loading and unloading tool 100, and helps to reduce the maintenance cost of the quick-change core loading and unloading tool 100. The guide section 220 passes through the mounting through hole 610, which simplifies the assembly process of the quick-change core loading and unloading tool 100, reduces the assembly time, and thus improves the assembly efficiency of the quick-change core loading and unloading tool 100. The guide section 220 passes through the mounting through hole 610, and the cross-sectional shape of the guide section 220 is the same as that of the mounting through hole 610. This ensures that the impact part 600 can only move relative to the tool body 200 along the first direction, and cannot rotate relative to the tool body 200.

[0031] According to some embodiments of the present invention, the guide segment 220 is formed with a first guide structure, and the impact portion 600 is formed with a second guide structure. The first guide structure and the second guide structure cooperate to guide the impact portion 600 in a first direction.

[0032] For example, a guide groove extending in a first direction can be formed along the outer peripheral wall of the guide segment 220. The remaining part of the outer peripheral wall of the guide segment 220, excluding the guide groove, is a smooth plane. The guide groove is a first guiding structure. Multiple circumferential guide grooves can be provided along the outer peripheral wall of the guide segment 220. A guide boss can be provided on the inner peripheral wall of the mounting through hole 610. The guide boss is a second guiding structure. Multiple circumferential guide bosses can be provided along the inner peripheral wall of the mounting through hole 610. The number of guide bosses can match the number of guide grooves, and at least a portion of the structure of the guide boss is assembled in the corresponding guide groove. Along the first direction, the size of the guide boss can be smaller than the size of the guide groove. When assembling the quick-change core 300, the mounting slot 210 of the tool body 200 can be aligned with the quick-change core 300, which can push the impact part 600 to move towards the impact block 400. The guide boss of the impact part 600 can slide in the guide groove of the guide segment 220, ensuring that the impact part 600 moves linearly along the first direction and reducing the risk of the impact part 600 getting stuck. The impact part 600 impacts the impact block 400, causing the quick-change core loading and unloading tool 100 to come into contact with the quick-change core 300. Then, the impact part 600 can be rotated, causing the tool body 200 to rotate, thereby tightening the threads of the quick-change core 300. When the quick-change core 300 is disassembled, the impact part 600 moves towards the limiting structure 500, the guide boss slides along the guide groove, and the impact part 600 impacts the limiting structure 500, separating the quick-change core loading and unloading tool 100 from the quick-change core 300.

[0033] Except for the first guide structure, the rest of the guide section 220 can be a smooth plane. This smooth plane can be formed by milling, reducing the sliding resistance of the impact part 600. This facilitates the sliding of the impact part 600 along the first direction, reduces friction between the guide section 220 and the impact part 600, and lowers the risk of the impact part 600 rotating circumferentially along the guide section 220. The arrangement of the first and second guide structures ensures that the movement of the impact part 600 is restricted to the first direction, allowing for precise control of its movement. This reduces the risk of inaccurate impact positioning due to deviation during sliding, and eliminates the need for personnel to control the movement direction of the impact part 600 when using the quick-change core loading and unloading tool 100. This simplifies the operation of the quick-change core loading and unloading tool 100 and improves its ease of use.

[0034] According to some embodiments of the present invention, such as Figure 2 , Figure 3 As shown, the tool body 200 also has a mounting section 230. Along the first direction, the mounting section 230 is located on the side of the guide section 220 away from the impact block 400 and is connected to the guide section 220. The limiting structure 500 is assembled on the mounting section 230.

[0035] In one embodiment, the outer peripheral wall of the mounting section 230 has external threads, and the limiting structure 500 is annular with a threaded hole. The limiting structure 500 is fitted onto the externally threaded portion of the mounting section 230, and the external threads and the internal threads of the threaded hole are engaged. In another embodiment, the limiting structure 500 can be welded to the mounting section 230. The connection between the mounting section 230 and the guide section 220 helps to fix the relative positions of the mounting section 230 and the guide section 220, which helps to improve the structural positional stability of the quick-change core loading and unloading tool 100. During the loading and unloading of the quick-change core 300, the impact part 600 impacts the limiting structure 500, generating a second impact force. The connection between the mounting section 230 and the guide section 220 helps to disperse the second impact force together, which helps to reduce the risk of stress concentration in the quick-change core loading and unloading tool 100.

[0036] According to some embodiments of the present invention, the outer peripheral wall of the limiting structure 500 is formed with a plurality of disassembly and assembly planes, which are arranged sequentially along the circumference of the limiting structure 500.

[0037] The number of disassembly and assembly planes can be set to two, three, four, five, six, etc. As one embodiment, six disassembly and assembly planes can be set, with two planes forming a group. The two planes in each group are located on opposite sides of the limiting structure 500, and are parallel to each other. As another embodiment, multiple disassembly and assembly planes can be set as five non-parallel planes evenly distributed along the circumference of the limiting structure 500. This application uses the example of multiple disassembly and assembly planes set as groups of two planes, with the two planes in each group being parallel. Compared to having no disassembly and assembly planes, the presence of these planes allows the tool to clamp onto them, eliminating the need for personnel to spend a significant amount of time searching for the leverage point of the limiting structure 500. When the limiting structure 500 and the mounting section 230 are connected by a threaded connection, it facilitates the rotation of the limiting structure 500, making it easier to remove the limiting structure 500 from the mounting section 230. This improves the convenience of operating the quick-change core loading and unloading tool 100. When the tool clamps the disassembly and assembly plane, a clamping force is generated. The setting of multiple disassembly and assembly planes helps to evenly distribute the clamping force, which helps to reduce the risk of deformation or damage to the limiting structure 500 due to stress concentration, helps to protect the structural integrity of the limiting structure 500, and thus helps to extend the service life of the limiting structure 500.

[0038] According to some embodiments of the present invention, the limiting structure 500 is detachably provided on the mounting section 230.

[0039] In one embodiment, the outer peripheral wall of the mounting section 230 is formed with external threads, and the limiting structure 500 is annular with a threaded hole. The limiting structure 500 is sleeved on the portion of the mounting section 230 with external threads, and the external threads and the internal threads of the threaded hole are engaged to connect, so that the limiting structure 500 is detachably mounted on the mounting section 230. In another embodiment, the mounting section 230 may have a first mounting hole through the mounting section 230 in a direction perpendicular to the first direction, and the limiting structure 500 may have a second mounting hole at a position corresponding to the first mounting hole. After the limiting structure 500 is sleeved on the mounting section 230, the first mounting hole and the second mounting hole are aligned, and a cylindrical pin or elastic pin is inserted, so that the limiting structure 500 is detachably mounted on the mounting section 230.

[0040] The limiting structure 500 is frequently subjected to impacts from the impact section 600 during use of the quick-change core loading and unloading tool 100. Prolonged use can easily lead to deformation or damage to the limiting structure 500. The detachable connection between the limiting structure 500 and the mounting section 230 allows for individual replacement of the deformed or damaged limiting structure 500 without replacing the entire quick-change core loading and unloading tool 100, thus reducing maintenance costs. Different specifications of quick-change cores 300 may have different impact force requirements. The detachable connection between the limiting structure 500 and the mounting section 230 allows for easy replacement of the quick-change core loading and unloading tool 100 with different impact force requirements, improving its versatility.

[0041] According to some embodiments of the present invention, the outer peripheral wall of the tool body 200 is formed with an external thread, the limiting structure 500 is annular to form a threaded hole, the limiting structure 500 is sleeved on the part of the tool body 200 with the external thread, and the external thread and the internal thread of the threaded hole are engaged and connected.

[0042] The limiting structure 500 and the tool body 200 are connected by a threaded connection, which is beneficial for personnel to adjust the distance between the limiting structure 500 and the impact block 400 when installing the quick-change core loading and unloading tool 100. This helps ensure that the length of the movement path of the impact part 600 between the impact block 400 and the limiting structure 500 meets the loading and unloading requirements of the quick-change core 300. It also helps to simplify the disassembly and assembly difficulty of the quick-change core loading and unloading tool 100 and reduce the disassembly and assembly time of the quick-change core loading and unloading tool 100, thereby improving the disassembly and assembly efficiency of the quick-change core loading and unloading tool 100. The limiting structure 500 and the tool body 200 are connected by a threaded connection, which allows personnel to disassemble and assemble the limiting structure 500 and the tool body 200 without the need for other tools. This simplifies the operation of disassembling and assembling the quick-change core loading and unloading tool 100 and further facilitates the replacement of deformed or damaged limiting structures 500 without replacing the entire quick-change core loading and unloading tool 100, thereby reducing the maintenance cost of the quick-change core loading and unloading tool 100. Different specifications of quick-change cores 300 may have different impact force requirements. The threaded connection between the limiting structure 500 and the tool body 200 further facilitates the replacement of quick-change cores 300 with quick-change cores 300 adapted to different impact force requirements, further improving the versatility of the quick-change core loading and unloading tool 100.

[0043] According to some embodiments of the present invention, the impact block 400 and the tool body 200 are integrally formed.

[0044] The integral molding of the impact block 400 and the tool body 200 facilitates the formation of a continuous structure between them, improves the structural continuity of the quick-change core loading and unloading tool 100, reduces the number of parts, simplifies the manufacturing process, enhances the relative positional accuracy of the impact block 400 and the tool body 200, and ensures that the impact part 600 can accurately impact the impact block 400. This, in turn, improves the reliability of the quick-change core loading and unloading tool 100, reduces the risk of relative wobbling between the impact block 400 and the tool body 200 due to structural gaps, and facilitates the storage of the quick-change core loading and unloading tool 100. When the impact part 600 impacts the impact block 400, a first impact force is generated. The impact block 400 and the tool body 200 are integrally formed, which helps the impact block 400 and the tool body 200 to jointly disperse the first impact force. This helps to reduce the risk of deformation or damage to the impact block 400 caused by stress concentration in the quick-change core loading and unloading tool 100, and further helps to extend the service life of the quick-change core loading and unloading tool 100.

[0045] Other configurations and operations of the quick-change core loading and unloading tool 100 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
