Description

Technical Field

[0001] The utility model relates to the application field of cast iron technology, in particular to a sampling die for spectral analysis of cast iron white cast iron. Background Art

[0002] Whitening of cast iron refers to the formation of a characteristic white microstructure during the cooling process. This microstructure is primarily due to an incomplete transformation between ferrite and pearlite or other factors. The main causes of whitening of cast iron include cooling rate, alloying element content, heat treatment process, and mechanical stress. Whitening affects cast iron primarily in the following aspects: mechanical properties, wear resistance, machinability, and corrosion resistance. In short, analyzing the causes and effects of whitening of cast iron is crucial for controlling its quality and performance.

[0003] In steel production, sampling and testing is a crucial link. It plays an irreplaceable role in ensuring the quality of steel products, optimizing the production process, improving production efficiency and ensuring production safety.

[0004] Direct reading spectrometers can complete the elemental content analysis of steel samples in a very short time, usually less than 40 seconds. This fast analysis capability is crucial for the composition control in the steel production process, especially in the need for synchronous analysis before the smelting furnace.

[0005] Cast iron sampling molds are essential tools for obtaining molten iron samples in the foundry industry. They are primarily used to quickly determine the chemical composition of molten iron at the furnace level, guiding the steelmaking process and ensuring the mechanical properties of the final product. In direct reading spectrometry analysis, the cast iron sample must be completely white to ensure accurate analysis results.

[0006] The cast iron sampling mold can cast samples of a certain shape, which is convenient for detection using a spectrometer. The existing technical solutions include Announcement No. CN214472123U, which designs and divides the combinable mold to conduct the heat of the pouring liquid to the surrounding area, prevent the appearance of obvious hot junction areas, and avoid fractures caused by excessive stress during the solidification process. However, the manufacturing cost is high, and the design of the combined structure makes the operation complicated and not very convenient. Similar Announcement No. CN216349895U is difficult to demold, has a very complex structure, and has high manufacturing costs.

[0007] Publication No. CN215448700U addresses the need for long-term mold use by adding a replaceable chiller block. However, this does not address the difficulty of mold release, hindering operator efficiency. Furthermore, without coordination restrictions, operators are prone to arbitrarily replacing noncompliant heat sinks, which can lead to white cast. Utility Model Content

[0008] In order to solve the above technical problems, the utility model provides a sampling mold for spectral analysis of cast iron whitening. The casting cavity is additionally provided with an overflow groove and an exhaust groove to improve the quality of the casting. In addition, the mold cavity is flat and designed with a draft angle to facilitate demolding of the casting. At the same time, the volume of the large heat dissipation base is increased so that the pouring liquid can be cooled quickly to ensure the whitening effect of the cast iron.

[0009] The technical solution of the utility model is: a sampling mold for spectroscopic analysis of cast iron whitening, comprising a large base, an inclined base and a mold body used in conjunction with the inclined base, the large base and the inclined base being detachably connected, the mold body being inserted along the inclined surface of the inclined base and abutting between the inclined base and the large base;

[0014] Furthermore, the mold body is provided with an exhaust groove, one end of the exhaust groove extends to the casting cavity and is connected to the casting cavity, and the other end of the exhaust groove extends to the upper end surface of the mold body.

[0015] Furthermore, the inner diameter of the casting cavity is smaller than the outer diameter of the casting cavity.

[0016] Furthermore, the mold body is provided with an overflow groove, one end of which extends to the casting cavity and is connected to the casting cavity.

[0017] The beneficial technical effects of the utility model are:

[0018] 1. Increase the volume of the heat dissipation base so that the pouring liquid can be cooled quickly to ensure the white cast iron effect.

[0019] 2. The part of the mold body with the casting cavity is an inclined wedge structure, which is positioned by the slope of the inclined base. It is a nested design.

[0030] In order to more clearly understand the technical means of the utility model, and can be implemented according to the content of the specification, the specific embodiment of the utility model is further described in detail in conjunction with the drawings and examples, the following examples are used to explain the utility model, but not to limit the scope of the utility model.

[0031] It should be noted that the terms "first", "second" and the like in the specification and claims of the application and the above-mentioned drawings are used to distinguish similar objects, and do not have to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the application described herein.

[0032] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate orientations or positional relationships based on the descriptions in the embodiments and shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present utility model.

[0033] like Figure 1-Figure 4 As shown, the utility model specifically relates to a sampling mold for spectroscopic analysis of cast iron whitening, comprising a large base 100, an inclined base 200, and a mold body 300 used in conjunction with the inclined base 200. The large base 100 and the inclined base 200 are detachably connected, and the mold body 300 is inserted along the inclined surface of the inclined base 200 and abuts between the inclined base 200 and the large base 100.

[0034] The mold body 300 abuts against the large base 100 and forms a pouring port 310 located on the upper end surface of the mold body 300 . The mold body 300 is provided with a pouring cavity 330 , and the pouring cavity 330 is connected to the pouring port via a pouring runner 320 .

[0035] It should be noted that the large base 100 is a rectangular parallelepiped structure made of brass or copper. The inclined base 200 is a right-angled trapezoidal structure, and the vertical surface of one end of the inclined base 200 abuts the vertical surface of the large base 100, and the connection is detachable. One end of the mold body 300 is a wedge structure used in conjunction with the slope 220. The mold body 300 relies on its own gravity to be inserted along the slope 220 between the inclined base 200 and the large base 100, so that the vertical surface of the mold body 300 abuts the vertical surface of the large base 100 and forms a sealed space for the casting cavity 330. The casting liquid enters the sealed space formed by the mold body 300 and the large base 100 through the casting port to form a cast product.

[0036] Furthermore, the mold body 300 is provided with a handle 400, which is connected to the mold body 300 via a rotating shaft and can be flipped relative to the mold body 300; when the mold body 300 is assembled, the handle 400 is flipped so that the head end of the handle 400 abuts against one side of the large base 100. At this time, the large base 100 is covered by the handle 400, and the position of the mold body 300 is further limited by the handle 400.

[0037] When demoulding is required, the handle 400 is turned over to keep it away from the large base 100 and the mold body 300 is lifted to separate the mold body 300 from the inclined base 200 and the large base 100, thereby completing the demoulding of the product.

[0038] The inclined base 200 is detachably connected to the large base 100 by bolts.

[0039] The inclined base 200 is provided with a step 211 , and the step 211 and the large base 100 are combined to form a gap groove 210 for matching with the mold body 300 .

[0040] Among them, the step 211 is located at the intersection of the slope 220 of the inclined base 200 and the vertical surface. When the inclined wedge structure of the mold body 300 is used in conjunction with the inclined base 200 and the large base 100 along the slope 220, one end of the inclined wedge structure is located in the gap groove 210, providing a moving space for the inclined wedge structure, further ensuring the stability of the fit between the mold body 300 and the inclined base 200 and the large base 100, and the sealing of the casting cavity 330.

[0041] The mold body 300 is provided with an exhaust groove 340 , one end of which extends to the casting cavity 330 and communicates with the casting cavity 330 , and the other end of which extends to the upper end surface of the mold body 300 .

[0042] When the pouring liquid flows into the pouring cavity 330 through the pouring port, the hot air generated can be released out of the mold body 300 through the exhaust groove 340 to ensure smooth pouring and molding.

[0043] The inner diameter of the pouring cavity 330 is smaller than the outer diameter of the pouring cavity 330 . The mold body 300 is provided with an overflow groove 350 . One end of the overflow groove 350 extends to the pouring cavity 330 and communicates with the pouring cavity 330 .

[0044] When the pouring liquid flows into the pouring cavity 330 through the pouring port, the pouring liquid with condensation or adsorbed pollutants at the front end enters the overflow trough 350, which can ensure that the quality of the molded casting is qualified.

[0045] After the product is demoulded, the overflow groove 350 and the exhaust groove 340 of the product are polished to retain the final product formed by the pouring cavity 330 and the pouring runner 320.

[0046] The above embodiments are only specific implementation methods of the present invention, which are used to illustrate the technical solutions of the present invention rather than to limit them. The protection scope of the present invention is not limited thereto. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in this field should understand that any technician familiar with this technical field can still modify the technical solutions recorded in the above embodiments within the technical scope disclosed by the present invention, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included in the protection scope of the present invention.
