[0006] According to an embodiment of the present invention, the venting channel processing device for molds, by setting a device body and a cutting body, with one cutting edge of the cutting body protruding from one end of the device body, can apply pressure to the device body, so that the cutting edge protruding from the device body is embedded into the mold surface under the action of impact force, so that the linear venting channel is formed in one step without damaging the mold, which is beneficial to improving the processing accuracy of the venting channel. In addition, the venting channel processing device is easy to operate and use, thereby improving the processing efficiency of the venting channel and reducing the production cost of the venting channel.

The surface of the first wall segment facing the mounting groove is configured as a first inclined surface, and the surface of the second wall segment facing the mounting groove is configured as a second inclined surface. From the bottom of the mounting groove to the open end of the mounting groove, the first inclined surface is inclined in a direction away from the second wall segment, and the second inclined surface is inclined in a direction away from the first wall segment. The first and second inclined surfaces are adapted to cooperate with the sub-side wall for limiting.

[0008] In some embodiments of the present invention, both the first inclined plane and the second inclined plane are planes.

[0009] In some embodiments of the present invention, the first limiting wall further has a third wall segment connected to the first wall segment, and the second limiting wall further has a fourth wall segment connected to the second wall segment. The third wall segment and the fourth wall segment are opposite to each other. Along the depth direction of the mounting groove, the third wall segment is located outside the first wall segment, and the fourth wall segment is located outside the second wall segment. Both the third wall segment and the fourth wall segment are provided with at least one locking element.

[0010] In some embodiments of the present invention, both the third wall segment and the fourth wall segment are formed with threaded holes, and the locking member has a screw that is fitted into the corresponding threaded hole. The screw on the third wall segment and the screw on the fourth wall segment are respectively adapted to abut against two adjacent sub-side walls.

[0011] In some embodiments of the present invention, both the third and fourth wall sections are parallel to the depth direction of the mounting groove.

[0012] In some embodiments of the present invention, the distance between the locking member and one end of the device body along the depth direction of the mounting groove is H, which satisfies the relationship: 5mm≤H≤7mm.

[0013] In some embodiments of the present invention, the first inclined plane and the second inclined plane are perpendicular, and the cross-section of the blade is square.

[0014] In some embodiments of the present invention, the main body of the device is further formed with a clearance hole.

[0034] 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.

[0035] The following is for reference. Figures 1-2This application describes an exhaust duct processing apparatus 100 for a mold according to an embodiment of the present invention. The exhaust duct processing apparatus 100 is used to process the exhaust duct of the mold. As some embodiments of this application, the mold may be configured as an engine cylinder head casting mold. As some embodiments of this application, the mold may be configured as a core box for producing sand cores. This application describes the exhaust duct processing apparatus 100 as an example with its vertical orientation.

[0036] like Figure 1 and Figure 2 As shown, the exhaust channel processing device 100 for a mold according to an embodiment of the present invention includes: a device body 1, one end of which is formed with a mounting groove 11 recessed toward the device body 1, the mounting groove 11 having opposing first limiting walls 111 and second limiting walls 112; a blade 2, the sidewall 21 of the blade 2 having a plurality of sub-sidewalls 211 connected end to end, any two adjacent sub-sidewalls 211 forming an included angle, and the intersection of any two adjacent sub-sidewalls 211 forming a cutting edge 22, when the blade 2 is assembled in the mounting groove 11, any two adjacent sub-sidewalls 211 respectively limit and cooperate with the first limiting wall 111 and the second limiting wall 112, and one cutting edge 22 of the blade 2 protrudes from one end of the device body 1; and a locking member 3, the locking member 3 being assembled in the device body 1, and the locking member 3 limiting and cooperating with the blade 2 to fix the blade 2 in the mounting groove 11.

[0037] The exhaust duct processing device 100 includes a device body 1, a cutting tool 2, and a locking member 3. One end of the device body 1 has a mounting groove 11, which is recessed into the device body 1. The mounting groove 11 provides an assembly position for the cutting tool 2, allowing it to be smoothly assembled into the device body 1. The mounting groove 11 has a first limiting wall 111 and a second limiting wall 112, which are arranged opposite to each other. This arrangement facilitates the cooperation of the first limiting wall 111 and the second limiting wall 112 to jointly limit the cutting tool 2. Along the height direction of the exhaust duct processing device 100, this reduces the risk of the cutting tool 2 moving into the mounting groove 11, thereby improving the positional stability of the cutting tool 2.

[0038] The sidewall 21 of the blade body 2 has multiple sub-sidewalls 211. It should be noted that the sidewall 21 of the blade body 2 has at least three sub-sidewalls 211. For example, the sidewall 21 of the blade body 2 may have, but is not limited to, three, four, or more sub-sidewalls 211. This application uses a sidewall 21 of the blade body 2 having four sub-sidewalls 211 as an example. The four sub-sidewalls 211 are connected end-to-end to form the sidewall 21 of the blade body 2. An angle is formed between any two adjacent sub-sidewalls 211 so that the intersection of any two adjacent sub-sidewalls 211 forms the cutting edge 22.

[0039] In some embodiments of this application, the blade body 2 has a square cross-section. When the blade body 2 is assembled in the mounting groove 11, the two adjacent sub-side walls 211 of the blade portion 22 opposite to the blade portion 22 of the protruding device body 1 are respectively limited and engaged with the first limiting wall 111 and the second limiting wall 112. In some embodiments of this application, the blade body 2 has a triangular cross-section. From the bottom of the mounting groove 11 to the open end of the mounting groove 11, the first limiting wall 111 and the second limiting wall 112 extend obliquely towards each other, forming a longitudinal cross-section similar to an inverted cone structure. When the blade body 2 is assembled in the mounting groove 11, the two adjacent sub-side walls 211 of the blade portion 22 of the protruding device body 1 are respectively limited and engaged with the first limiting wall 111 and the second limiting wall 112. When one of the cutting edges 22 of the cutter body 2 is damaged, the assembly angle of the cutter body 2 is adjusted so that the other cutting edge 22 of the cutter body 2 protrudes from the main body 1 of the device. This allows any two adjacent sub-side walls 211 to abut against the first limiting wall 111 and the second limiting wall 112 respectively. Along the height direction of the exhaust channel processing device 100, the risk of the cutter body 2 moving into the mounting groove 11 can be reduced, thereby reducing the risk that the cutting edge 22 will move into the mounting groove 11 along with the cutter body 2. This is beneficial for one of the cutting edges 22 of the cutter body 2 to protrude from one end of the main body 1 of the device. When the exhaust channel processing device 100 is placed in the vertical direction, one end of the main body 1 of the device is the lower end of the main body 1, which makes it easier for one of the cutting edges 22 protruding from one end of the main body 1 to process the exhaust channel, thus facilitating the smooth processing of the exhaust channel.

[0040] The locking member 3 is assembled to the device body 1. Further, the locking member 3 is assembled to the first limiting wall 111 and the second limiting wall 112 of the device body 1. As some embodiments of this application, the locking member 3 can be constructed as a bolt, and the locking member 3 can be screwed to the device body 1. As some embodiments of this application, the locking member 3 can be constructed as a pin, and the locking member 3 can be inserted into the device body 1. The locking member 3 and the cutter body 2 are mutually limitingly engaged, so that one end of the locking member 3 located in the mounting groove 11 can abut against the cutter body 2. Along the height direction of the exhaust duct processing device 100, the risk of the cutter body 2 moving away from the mounting groove 11 can be reduced, thereby fixing the cutter body 2 within the mounting groove 11, improving the structural stability of the exhaust duct processing device 100, and further reducing the risk of the exhaust duct processing device 100 failing due to the cutter body 2 moving out of the mounting groove 11.

[0041] Furthermore, multiple locking elements 3 can be provided. For example, there may be, but is not limited to, two, three, four, or more locking elements 3. This application uses four locking elements 3 as an example for illustration. Having four locking elements 3 allows them to be evenly distributed on the first limiting wall 111 and the second limiting wall 112, improving the uniformity of force on the two adjacent sub-side walls 211 where the cutter body 2 and the locking element 3 cooperate, and reducing the risk of damage to the cutter body 2 due to uneven force on the sub-side walls 211. Having multiple locking elements 3 also improves the locking reliability of the locking elements 3. When any one of the locking elements 3 is at risk of cracking or even breaking, the other locking elements 3 can continue to perform their locking function, thereby further improving the structural stability of the exhaust channel processing device 100.

[0042] Specifically, the blade 2 is assembled into the mounting groove 11 of the device body 1. Along the height direction of the exhaust duct processing device 100, the first limiting wall 111 and the second limiting wall 112 can limit the risk of the blade 2 moving into the mounting groove 11, so that one cutting edge 22 of the blade 2 protrudes from one end of the device body 1. Along the height direction of the exhaust duct processing device 100, the locking member 3 cooperates with the blade 2 to limit the risk of the blade 2 moving away from the mounting groove 11, thereby achieving the effect of fixing the blade 2 in the mounting groove 11.

[0043] When machining the venting channel, it is not necessary to remove the mold and place it separately. Lines can be drawn on the surface of the mold where the venting channel needs to be machined for positioning. It should be noted that the spacing between two adjacent lines is approximately 3mm. The venting channel machining device 100 is placed directly on the mold, with the cutting edge 22 at one end of the protruding device body 1 aligned with the scribed line. A hammer is then used to strike the surface of the device body 1 away from the mounting groove 11. Under the impact force, the cutting edge 22 embeds into the mold surface, thereby achieving the effect of machining the venting channel in the mold. This improves the working effect of the mold's venting system and reduces the risk of rework and high scrap rates due to poor venting performance.

[0044] Therefore, by setting up the device body 1 and the blade 2, with one blade 22 of the blade 2 protruding from one end of the device body 1, pressure can be applied to the device body 1 so that the blade 22 protruding from the device body 1 embeds into the mold surface under the action of impact force. Without damaging the mold, the linear exhaust channel is formed in one step, which is beneficial to improving the processing accuracy of the exhaust channel. Furthermore, the exhaust channel processing device 100 has a simple structure, is easy to manufacture, and is not easily damaged. Moreover, the exhaust channel processing device 100 is easy to operate and convenient to use, which is beneficial to improving the processing efficiency of the exhaust channel and reducing the production cost of the exhaust channel.

[0045] In some embodiments of the present invention, such as Figure 1As shown, the first limiting wall 111 has a first wall segment 1111, and the second limiting wall 112 has a second wall segment 1121 opposite to the first wall segment 1111. The surface of the first wall segment 1111 facing the mounting groove 11 is constructed as a first inclined surface 1112, and the surface of the second wall segment 1121 facing the mounting groove 11 is constructed as a second inclined surface 1122. From the bottom of the mounting groove 11 to the open end of the mounting groove 11, the first inclined surface 1112 is inclined in a direction away from the second wall segment 1121, and the second inclined surface 1122 is inclined in a direction away from the first wall segment 1111. The first inclined surface 1112 and the second inclined surface 1122 are adapted to be limited and engaged with the sub-side wall 211.

[0046] The first limiting wall 111 has a first wall segment 1111, and the second limiting wall 112 has a second wall segment 1121, with the first wall segment 1111 and the second wall segment 1121 arranged opposite to each other. Furthermore, the first wall segment 1111 and the second wall segment 1121 are symmetrically arranged, which allows the first wall segment 1111 and the second wall segment 1121 to evenly distribute pressure when bearing load, thereby reducing the risk of stress concentration in either the first wall segment 1111 or the second wall segment 1121.

[0047] The surface of the first wall segment 1111 facing the mounting groove 11 is constructed as a first inclined surface 1112, and the surface of the second wall segment 1121 facing the mounting groove 11 is constructed as a second inclined surface 1122. From the bottom of the mounting groove 11 to the open end of the mounting groove 11, the first inclined surface 1112 is inclined in a direction away from the second wall segment 1121, and the second inclined surface 1122 is inclined in a direction away from the first wall segment 1111, so that the first inclined surface 1112 and the second inclined surface 1122 intersect or the extension line of the first inclined surface 1112 intersects the extension line of the second inclined surface 1122.

[0048] When the cutter body 2 is assembled in the mounting groove 11, the first inclined surface 1112 and the second inclined surface 1122 respectively limit the engagement with the two adjacent sub-side walls 211 of the cutter body 2, so that the two adjacent sub-side walls 211 of the cutter body 2 can abut against the first inclined surface 1112 and the second inclined surface 1122 respectively. Along the height direction of the exhaust channel processing device 100, the risk of the cutter body 2 moving into the mounting groove 11 can be reduced, which is conducive to the fact that one of the cutting edges 22 of the cutter body 2 can protrude from one end of the device body 1, thereby facilitating the smooth processing of the exhaust channel.

[0049] As some embodiments of this application, the main body 1 of the device can be made of 45# steel, and can be a cuboid with a side length of 50mm*50mm*60mm, and the hardness of the main body 1 after quenching is HRC45. As some embodiments of this application, the included angle between the first inclined plane 1112 and the second inclined plane 1122, or the included angle between the extension line of the first inclined plane 1112 and the extension line of the second inclined plane 1122, can be 90°.

[0050] In some embodiments of the present invention, such as Figure 1 As shown, both the first inclined plane 1112 and the second inclined plane 1122 are planes.

[0051] The first inclined surface 1112 and the second inclined surface 1122 are both planar. This configuration improves the fit between the first inclined surface 1112 and the second inclined surface 1122 and the corresponding sub-sidewall 211, thereby improving the machining accuracy of the exhaust channel. Furthermore, since the first inclined surface 1112 and the second inclined surface 1122 are both planar, the risk of deformation or even damage to the corresponding sub-sidewall 211 caused by uneven surfaces of the first inclined surface 1112 and the second inclined surface 1122 is reduced. This helps to extend the service life of the tool body 2, thereby extending the service life of the exhaust channel machining device 100.

[0052] In some embodiments of the present invention, such as Figure 1 As shown, the first limiting wall 111 also has a third wall segment 1113 connected to the first wall segment 1111, and the second limiting wall 112 also has a fourth wall segment 1123 connected to the second wall segment 1121. The third wall segment 1113 and the fourth wall segment 1123 are opposite each other. Along the depth direction of the mounting groove 11, the third wall segment 1113 is located outside the first wall segment 1111, and the fourth wall segment 1123 is located outside the second wall segment 1121. Both the third wall segment 1113 and the fourth wall segment 1123 are provided with at least one locking element 3.

[0053] The first limiting wall 111 further includes a third wall segment 1113, which is connected to the first wall segment 1111. The second limiting wall 112 further includes a fourth wall segment 1123, which is connected to the second wall segment 1121. In some embodiments of this application, the third wall segment 1113 and the first wall segment 1111, and the fourth wall segment 1123 and the second wall segment 1121, can all be integrally formed. In some embodiments of this application, the third wall segment 1113 and the first wall segment 1111, and the fourth wall segment 1123 and the second wall segment 1121, can all be separately processed and then welded together.

[0054] This application uses the example of the third wall segment 1113 being integrally formed with the first wall segment 1111 and the fourth wall segment 1123 being integrally formed with the second wall segment 1121. That is, the third wall segment 1113 and the first wall segment 1111 are constructed as an integrally formed part, and the fourth wall segment 1123 and the second wall segment 1121 are constructed as an integrally formed part. The integrally formed part has good structural strength. By making the third wall segment 1113 and the first wall segment 1111, and the fourth wall segment 1123 and the second wall segment 1121 integrally formed, the connection reliability of the third wall segment 1113 and the first wall segment 1111, and the fourth wall segment 1123 and the second wall segment 1121 can be improved, and the probability of breakage at the connection between the third wall segment 1113 and the first wall segment 1111, and the fourth wall segment 1123 and the second wall segment 1121 can be reduced, thereby improving the structural strength of the first limiting wall 111 and the second limiting wall 112.

[0055] Along the depth direction of the mounting groove 11, the third wall section 1113 is located outside the first wall section 1111, and the fourth wall section 1123 is located outside the second wall section 1121. This arrangement makes the structure of the main body 1 of the device reasonable. When processing the exhaust channel, it is beneficial for the end wall of the third wall section 1113 away from the first wall section 1111 to abut against the mold, and it is also beneficial for the end wall of the fourth wall section 1123 away from the second wall section 1121 to abut against the mold, reducing the risk of the cutting edge 22 embedding too deeply into the mold, thereby improving the processing accuracy of the exhaust channel.

[0056] The third wall segment 1113 and the fourth wall segment 1123 are arranged opposite to each other, and each of the third wall segment 1113 and the fourth wall segment 1123 is provided with at least one locking element 3. As some embodiments of this application, each of the third wall segment 1113 and the fourth wall segment 1123 is provided with one locking element 3. As some embodiments of this application, each of the third wall segment 1113 and the fourth wall segment 1123 is provided with two locking elements 3. This application describes the situation with an example where each of the third wall segment 1113 and the fourth wall segment 1123 is provided with two locking elements 3, which can improve the locking reliability of the locking elements 3. When any one of the locking elements 3 is at risk of cracking or even breaking, the other locking element 3 can continue to play a locking role, thereby further improving the working stability of the blade body 2. Since the third wall section 1113 and the fourth wall section 1123 are arranged opposite to each other, the locking parts 3 on the third wall section 1113 and the fourth wall section 1123 can uniformly limit the two adjacent sub-side walls 211, which is beneficial to the uniformity of the force on the two adjacent sub-side walls 211, reduces the risk of the cutter body 2 shaking due to uneven force, and thus helps to improve the stability of the cutter body 2.

[0057] In some embodiments of the present invention, such as Figure 1As shown, both the third wall section 1113 and the fourth wall section 1123 have threaded holes 113. The locking member 3 has a screw 31, which is fitted into the corresponding threaded hole 113. The screw 31 on the third wall section 1113 and the screw 31 on the fourth wall section 1123 are respectively adapted to abut against two adjacent sub-side walls 211.

[0058] In some embodiments of this application, the locking member 3 can be constructed as a bolt. The locking member 3 has a screw 31, which can be fitted into a corresponding threaded hole 113 so that the screw 31 is disposed on the device body 1. At least a portion of the screw 31 can extend into the mounting groove 11, so that the screw 31 on the third wall section 1113 and the screw 31 on the fourth wall section 1123 respectively abut against two adjacent sub-side walls 211, thereby fixing the blade 2 in the mounting groove 11. Furthermore, by having a screw 31 in the locking member 3, the length of the screw 31 extending into the mounting groove 11 can be controlled by rotating the screw 31, so that the screw 31 can abut against blades 2 of different sizes, which is beneficial to improving the adaptability of the device body 1 to blades 2 of different sizes.

[0059] In some embodiments of this application, the number of threaded holes 113 and locking members 3 are both set to four. Two threaded holes 113 are located in the third wall section 1113, and two threaded holes 113 are located in the fourth wall section 1123. The four threaded holes 113 are constructed as M6 threaded holes 113, with all threads present in through holes. The hole spacing between the two threaded holes 113 on the third wall section 1113 is 30mm, and the hole spacing between the two threaded holes 113 on the fourth wall section 1123 is 30mm. The locking member 3 can be an M6*15mm long internal hexagonal screw 31 for limiting the position of the tool body 2.

[0060] In some embodiments of the present invention, such as Figure 1 As shown, the third wall section 1113 and the fourth wall section 1123 are both parallel to the depth direction of the mounting groove 11.

[0061] In this arrangement, the third wall segment 1113 and the fourth wall segment 1123 are both parallel to the depth direction of the mounting groove 11. This arrangement ensures that the third wall segment 1113 and the fourth wall segment 1123 are rationally positioned and are perpendicular to the horizontal plane. When processing the exhaust duct, the main body 1 of the device needs to be hammered with a hand hammer. At this time, the third wall segment 1113 and the fourth wall segment 1123 will bear a large impact force. Since the third wall segment 1113 and the fourth wall segment 1123 are both perpendicular to the horizontal plane, the risk of cracking or even breakage of the third wall segment 1113, the first wall segment 1111, the fourth wall segment 1123, and the second wall segment 1121 can be reduced, thereby further improving the structural stability of the main body 1 of the device.

[0062] In some embodiments of the present invention, such as Figure 2As shown, along the depth direction of the mounting groove 11, the distance between the locking member 3 and one end of the device body 1 is H, which satisfies the relationship: 5mm≤H≤7mm.

[0063] The distance H between the locking member 3 and one end of the device body 1 can satisfy the relationship: 5mm ≤ H ≤ 7mm. For example, the distance H between the locking member 3 and one end of the device body 1 can be set to 5mm, 6mm, or 7mm, but this application is not limited to this. The distance H between the locking member 3 and one end of the device body 1 can also be set to other lengths. This application takes a distance H between the locking member 3 and one end of the device body 1 set to 6mm as an example. This setting can reduce the risk of cracking of the third wall section 1113 and the fourth wall section 1123 due to excessively short distance H between the locking member 3 and one end of the device body 1, and can also reduce the risk of damage to the blade part 22 or failure of the limiting function due to excessively long distance H between the locking member 3 and one end of the device body 1.

[0064] In some embodiments of the present invention, such as Figure 1 As shown, the first inclined plane 1112 and the second inclined plane 1122 are perpendicular, and the cross-section of the blade body 2 is square.

[0065] The cross-section of the cutter body 2 is square. Compared with cutter bodies 2 with other cross-section shapes, the square cross-section of the cutter body 2 is easier to process and can reduce the production cost of the cutter body 2. The cutter body 2 can have four cutting edges 22. When one cutting edge 22 fails, the other cutting edges 22 can continue to perform processing functions, which helps to improve the service life of the cutter body 2. The first inclined surface 1112 and the second inclined surface 1122 are perpendicular or their extended surfaces are perpendicular. This arrangement makes the structural design of the device body 1 and the cutter body 2 more reasonable, which is conducive to the fitting of the cutter body 2 and the mounting groove 11 of the device body 1, and facilitates the smooth assembly of the cutter body 2 between the first inclined surface 1112 and the second inclined surface 1122, reducing the assembly difficulty of the exhaust channel processing device 100.

[0066] As some embodiments of this application, the blade body 2 can be made of W18Cr4V high-speed steel white steel bar, the size of the blade body 2 can be 20*20*50mm, and the hardness of the blade body 2 can be between HRC61 and 63.

[0067] In some embodiments of the present invention, such as Figure 1As shown, the main body 1 of the device also has a clearance hole 12. Along the depth direction of the mounting groove 11, the clearance hole 12 is located on the side of the mounting groove 11 away from the open end of the mounting groove 11 and adjacent to the mounting groove 11. Along the arrangement direction of the first limiting wall 111 and the second limiting wall 112, at least a part of the clearance hole 12 is located between the first limiting wall 111 and the second limiting wall 112. The clearance hole 12 communicates with the mounting groove 11. Another blade portion 22 of the blade body 2 is adapted to be fitted into the clearance hole 12.

[0068] In some embodiments of this application, along the height direction of the exhaust duct processing device 100, the vertical distance between the bottom of the mounting groove 11 and the end faces of the third and fourth side walls 21 of the device body 1 can be 28 mm. A clearance hole 12 is formed at the bottom of the mounting groove 11. That is, along the depth direction of the mounting groove 11, i.e., along the height direction of the exhaust duct processing device 100, the clearance hole 12 is located on the side of the mounting groove 11 facing away from the open end of the mounting groove 11. The clearance hole 12 is adjacent to the mounting groove 11, allowing the clearance hole 12 to reliably avoid the cutter body 2 within the mounting groove 11.

[0069] Along the arrangement direction of the first limiting wall 111 and the second limiting wall 112, at least a portion of the clearance hole 12 is located between the first limiting wall 111 and the second limiting wall 112, so that the clearance hole 12 communicates with the mounting groove 11. When the blade body 2 is assembled in the mounting groove 11, the blade portion 22 opposite to the blade portion 22 protruding from the device body 1 is assembled in the clearance hole 12, so as to reduce the risk of direct contact between the blade portion 22 and the device body 1, thereby reducing the risk of stress concentration at the contact point between the blade portion 22 and the device body 1, which is beneficial to improving the working reliability of the device body 1 and the blade portion 22. When force is applied to the device body 1, the risk of damage to the blade portion 22 or the part of the device body 1 in contact with the blade portion 22 is effectively reduced, thereby increasing the service life of the exhaust channel processing device 100.

[0070] As some embodiments of this application, the clearance hole 12 can be set as a square with a cross-sectional side length of 6mm. As some embodiments of this application, the clearance hole 12 can also be constructed as a circular clearance hole 12 with a diameter of 6mm. Such a setting can reduce the risk that the clearance hole 12 is too small and cannot reliably avoid the blade part 22, and can also reduce the risk that the structural strength of the device body 1 is reduced due to the clearance hole 12 being too large.

[0071] In some embodiments of the present invention, the exhaust duct processing device 100 may further include: a gasket (not shown in the figure), with a gasket provided between the first limiting wall 111 and the corresponding sub-side wall 211, and between the second limiting wall 112 and the corresponding sub-side wall 211, to adjust the height of one end of the blade portion 22 protruding from the device body 1.

[0072] The exhaust channel processing device 100 may also include a shim (not shown in the figure), which can adjust the height of one end of the blade portion 22 protruding from the main body 1. Specifically, shims may be provided between the first limiting wall 111 and the corresponding sub-side wall 211, and between the second limiting wall 112 and the corresponding sub-side wall 211. By changing the thickness and number of shims, the height of one end of the blade portion 22 protruding from the main body 1 can be adjusted as needed, thereby changing the depth of the blade portion 22 embedded in the mold surface, thus making the depth of the processed exhaust channel controllable and improving the flexibility of the exhaust channel depth control.

[0073] As some embodiments of this application, two shims each with thicknesses of 0.05mm, 0.10mm, and 0.15mm can be prepared. Without installing the shims, the blade portion 22 protruding from one end of the device body 1 is 0.25mm higher than the bottom surface of the device body 1. By adding shims of different thicknesses between the first limiting wall 111 and the corresponding sub-side wall 211, and between the second limiting wall 112 and the corresponding sub-side wall 211, the height of the blade portion 22 above the bottom surface of the device body 1 can be controlled. As some embodiments of this application, adding a 0.05mm shim can achieve the effect of the blade portion 22 being 0.3mm higher than the bottom surface of the device body 1.
