[0046] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present disclosure, and not to limit the present disclosure.
[0047] In order to make the drawing simple, only the parts related to the disclosure are shown in each figure, which does not represent the actual structure of the product. In addition, in order to make the drawing simple and easy to understand, in some figures, only one of the parts with the same structure or function is shown, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".
[0048] In this document, unless otherwise explicitly defined and limited, the terms "mount", "connected", "connection" should be interpreted broadly, for example, can be fixed connection, can also be detachable connection, or integrally connected; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.
[0049] In the present disclosure, unless otherwise explicitly defined and limited, the first feature "on" or "under" the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them.

[0051] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0052] As Figures 1-9 As shown in the figure, it shows a cast integrated with a profiling device in an embodiment of the present disclosure, which includes a frame body 200 with a receiving platform 100. A lower profiling mold 300 is arranged on the receiving platform 100, and an upper profiling mold 400 is arranged on the frame body 200 in a lifting manner, and the upper profiling mold 400 can move away from or close to the lower profiling mold 300 after lifting action.
[0053] The lower calibrating mold 300 is composed of a supporting piece 320, which is arranged on the main body 310. The supporting piece 320 has a supporting part 321 and an abutting part 322, wherein the supporting part 321 is used for supporting one end of the part 500 connected with the exhaust duct, and the abutting part 322 is used for abutting closely with one side of the part 500, so as to position the part 500. In addition, the sliding calibrating pieces 600 are arranged on the main body 310 in a sliding manner, and can move close to or away from each other after sliding. When the sliding calibrating pieces 600 move close to each other, they can abut closely with the side of the part 500, and the height of the sliding calibrating pieces 600 is higher than the height of the circular side wall 510 of the part 500. The sliding calibrating pieces 600 abut with the side of the part 500 from the side, and abut with the side of the part 500 through the same shape as the standard part 500, and the sliding calibrating pieces 600 abut with the side of the part 500 through mutual extrusion, so as to calibrate the part 500.
[0054] The upper calibrating mold 400 includes a lifting piece 410, which is arranged on the frame 200 in a lifting manner. The lower pressing calibrating piece 420 is arranged on the lifting piece 410, and the space between the side wall of the lower pressing calibrating piece 420 and the sliding calibrating piece 600 is used for calibrating the circular side wall 510 of the part 500.
[0055] In the actual calibrating operation, the part 500 is first placed on the supporting piece 320 and positioned through the supporting part 321 and the abutting part 322. Then the sliding calibrating pieces 600 move close to each other and abut with the side of the part 500. Then the upper calibrating mold 400 is lowered, the lower pressing calibrating piece 420 cooperates with the sliding calibrating piece 600, and the circular side wall 510 of the part 500 is calibrated.
[0056] Through the integrated calibrating device, the mutual influence between the multiple calibrating processes is avoided, and the accuracy and efficiency of the calibration are improved. The cooperation of the supporting piece 320 and the sliding calibrating piece 600 can stably position and preliminarily adjust the part 500, laying a foundation for the subsequent accurate calibration. The sliding calibrating pieces 600 can calibrate the part 500 through the way of moving close to or away from the part 500, which can better adapt to the shape of the special-shaped part and facilitate the purpose of synchronous calibration of multiple parts. The cooperation of the upper calibrating mold 400 and the lower calibrating mold 300 can comprehensively and accurately calibrate the part 500, and ensure that the shape and size of the part 500 meet the requirements.
[0057] In some examples, the lower pressing calibrating piece 420 is provided with a first inclined table 421 close to one end of the receiving platform 100. In the actual calibrating process, the first inclined table 421 plays an important role, which is used for gradually pressing the circular side wall 510 of the part 500 with the sliding calibrating piece 600.
[0058] When the upper mold 400 is lowered, the first inclined platform 421 first contacts the sliding mold 600 and gradually increases the pressing force on the circular side wall 510 as the lowering continues. This gradual pressing method can better adapt to the slightly deformed circular side wall 510, and the first inclined platform 421 can gradually push the slightly deformed side wall to the standard size.
[0059] The design of the first inclined platform 421 realizes gradual pressing during the sizing process, improves the accuracy and quality of sizing. Uniform force effectively reduces the damage to the part 500 due to inaccurate size caused by pouring, which is pressed by the upper mold 400 and the lower mold 300. It helps to prolong the service life of the part 500 and improve the reliability of the product.
[0060] In some examples, the support 320 has a through hole 323, which allows the valve drain 520 of the part 500 to pass through, on the one hand, the support 320 can better support the bottom of the upper end of the part 500, and on the other hand, the valve drain 520 is sized below. In actual sizing operation, the support 320 cooperates with the bottom of the lower pressing mold 420 to size the upper surface of the part 500.
[0061] The through hole 323 provides a suitable passage for the valve drain 520 of the part 500, ensuring the accuracy and stability of the placement of the part 500. The support 320 cooperates with the bottom of the lower pressing mold 420 to size the surface of the part 500, which can effectively improve the flatness and shape accuracy of the surface of the part 500. This cooperative sizing method simplifies the sizing operation and improves work efficiency.
[0062] In some examples, a guide inclined platform 710 is also included, which is arranged at the end of the sliding mold 600 away from each other. The pushing piece 720 is arranged on the lifting piece 410, and the pushing piece 720 is closer to the receiving platform 100 than the lower pressing mold 420.
[0063] In actual operation, when the lifting piece 410 is lowered, the pushing piece 720 first contacts the guide inclined platform 710. As the lifting piece 410 continues to lower, the pushing piece 720 pushes the sliding mold 600 closer to each other through the guide inclined platform 710. This pushing method can ensure that the sliding mold 600 accurately and synchronously approaches the part 500, thereby effectively clamping and sizing the part 500. Moreover, after the sliding mold 600 first approaches the part 500 to fix it, the lower pressing mold 420 then cooperates with the sliding mold 600 and the support 320 to size, realizing step-by-step sizing while maintaining the size of the previous sizing.
[0064] The cooperation of the guide inclined table 710 and the pushing piece 720 realizes the automatic and synchronous approach of the sliding calibration pieces 600, improves the efficiency and accuracy of the calibration operation, simplifies the operation process of the device, and reduces the working difficulty of the operator.
[0065] In some examples, a fixing piece 810 is further included and arranged on the main body 310. Two ends of the elastic piece 820 are arranged on the fixing piece 810 and the sliding calibration piece 600 respectively.
[0066] In actual work, when the pushing piece 720 pushes the sliding calibration pieces 600 to approach each other through the guide inclined table 710 to complete the calibration work, the lifting piece 410 rises, at this time, the elastic piece 820 plays a role, which provides a force for the mutual separation of the sliding calibration pieces 600, so that the sliding calibration pieces 600 return to the initial position, and prepare for the next calibration operation.
[0067] The arrangement of the elastic piece 820 enables the sliding calibration pieces 600 to automatically reset after completing the calibration, improves the working efficiency, and can reduce manual intervention, so that the operation is more convenient and automated.
[0068] In some examples, the fixing piece 810 is detachably arranged on the main body 310.
[0069] The fixing piece 810 can be fixed on the main body 310 by bolts, and the detachable fixing piece 810 facilitates the installation of the sliding calibration piece 600. When the sliding calibration piece 600 is installed, the fixing piece 810 can be first detached from the main body 310 to avoid interference between the fixing piece 810 and the sliding calibration piece 600.
[0070] In some examples, the diameter of the through hole 323 is greater than the diameter of the valve leakage door 520. Two cylindrical calibration pieces 900 are further included and arranged on the two sliding calibration pieces 600 respectively. The cylindrical calibration piece 900 has an opening 910, which is used for the valve leakage door 520 to pass through. In actual calibration, when the part 500 is placed on the supporting piece 320, the valve leakage door 520 passes through the through hole 323 and the opening 910 of the cylindrical calibration piece 900. The two cylindrical calibration pieces 900 cooperate with each other to calibrate the valve leakage door 520, so that it meets the specified shape and size requirements.
[0071] The diameter of the through hole 323 is greater than the diameter of the valve leakage door 520, which facilitates the valve leakage door 520 with deviation to pass through the through hole 323. The two cylindrical calibration pieces 900 are specially designed for the calibration of the valve leakage door 520, which improves the accuracy and pertinence of the calibration of the valve leakage door 520. It helps to ensure that each part of the entire part 500 can be accurately calibrated, and improves the overall quality of the product.
[0072] In some examples, there are two sliding jigs 600, each of which is provided with a cylindrical jig 900. The openings 910 of the two cylindrical jigs 900 are opposite to each other, and when the cylindrical jigs 900 abut each other, the inner walls of the cylindrical jigs 900 can tightly abut the outer wall of the valve disc 520.
[0073] In actual sizing operation, as the sliding jigs 600 approach each other, the two cylindrical jigs 900 also gradually approach and finally abut. At this time, the inner walls of the cylindrical jigs 900 completely fit the outer wall of the valve disc 520, thereby accurately sizing the valve disc 520.
[0074] The two opposite and abutting cylindrical jigs 900 can simultaneously size the valve disc 520 from both sides, ensuring uniformity and symmetry of sizing. The tight abutment of the inner walls of the cylindrical jigs 900 and the outer wall of the valve disc 520 improves the accuracy and effect of sizing, ensuring that the valve disc 520 reaches the ideal shape and size.
[0075] In some examples, the end of the opening 910 close to the other end has a guide slope 911. In actual sizing process, the guide slope 911 plays an important role, which is used to guide the valve disc 520 into the cylindrical jig 900. When the part 500 is placed and moved, the valve disc 520 first contacts the guide slope 911. Due to the presence of the guide slope 911, the valve disc 520 can smoothly enter the inside of the cylindrical jig 900 along the slope, achieving accurate positioning and sizing.
[0076] The design of the guide slope 911 can make the valve disc 520 enter the cylindrical jig 900 more easily and accurately, avoiding hard extrusion of the valve disc 520 and the cylindrical jig 900 due to the angle error of the valve disc 520.
[0077] It should be noted that the above examples are only used to illustrate the technical solutions of the present disclosure and not to limit it. Although the present disclosure has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present disclosure, which should be covered in the scope of the claims of the present disclosure.
