Description

Technical Field

[0001] The utility model relates to the technical field of metal casting equipment, in particular to a clamp type pouring cup for casting. Background Art

[0002] The information disclosed in the background technology of the present invention is only intended to increase the understanding of the overall background of the present invention, and shall not necessarily be regarded as an admission or suggestion in any form that the information constitutes the prior art already known to those skilled in the art.

[0003] The pouring cup for metal casting is a key component connecting the ladle and the mold. Its main function is to stabilize the flow of molten metal, remove inclusions and guide the molten metal to be smoothly injected into the mold cavity. However, in actual use, the existing pouring cup does not have a preheating function, resulting in the following adverse effects including but not limited to: First, when the cold pouring cup directly contacts the high-temperature molten metal, due to the huge temperature difference, significant thermal stress will be generated inside the pouring cup, which may cause cracks or even ruptures in the pouring cup, seriously affecting its service life and the safety of the casting process. Second, the unpreheated pouring cup will quickly absorb the heat of the molten metal, thereby accelerating the cooling of the molten metal. Too fast cooling will not only increase the temperature gradient inside the casting, resulting in increased thermal stress, but also may cause casting defects such as cold shut, shrinkage cavity, and cracks. Third, the surface of the cold pouring cup is prone to cause the slag to solidify prematurely and adhere to its surface, which will not only affect the normal flow of the molten metal, but also be brought into the mold cavity during the subsequent pouring process, forming casting defects such as slag holes. Fourthly, before each pouring, it is necessary to wait for the pouring cup to naturally heat up to a temperature close to that of the molten metal. This process will prolong the casting cycle and reduce production efficiency.

[0004] In addition, the existing casting pouring cup has poor thermal insulation performance, which causes the temperature of the molten metal to drop too quickly, increasing the probability of casting defects. Moreover, most filters are placed inside the pouring cup, making it difficult to clean the old sand, slag and metal residues left in the pouring cup, affecting subsequent pouring operations and casting quality. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a clamp-type pouring cup for casting which has a preheating function and is easy to clean daily.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A clamp-type pouring cup for casting, comprising a pouring cup body, wherein the pouring cup is in a trumpet shape with a large inlet end and a small outlet end;

[0008] A stirrup steel wire mesh is arranged inside the pouring cup body, a flame retardant heat-insulating sleeve is wrapped outside the pouring cup body, an electric heating wire mesh is arranged inside the flame retardant heat-insulating sleeve, and a clamp is arranged outside the heat-insulating sleeve;

[0009] A filter screen is arranged on the outside of the outlet end of the pouring cup body, and a holder is arranged on the outside of the pouring cup body near the outlet end. The filter screen is mounted on the holder by means of an adapted buckle.

[0010] Preferably, the pouring cup body is provided with an annular protrusion on the outside near the outlet end and above the holder.

[0011] Preferably, the flame retardant heat-insulating sleeve is mounted on top of the protrusion.

[0012] Preferably, the flame retardant thermal insulation sleeve is an asbestos sleeve.

[0013] The utility model has the following beneficial effects, including but not limited to:

[0014] The built-in stirrup wire mesh is built into the pouring cup body to enhance the structural stability and strength of the pouring cup body and prevent deformation or rupture under high temperature and high pressure environment. At the same time, the built-in stirrup wire mesh also helps to quickly heat up during preheating.

[0015] The outer side of the pouring cup body is equipped with a flame-retardant insulation sleeve and a built-in electric heating wire mesh, which can realize the preheating and insulation functions of the pouring cup, effectively solving a series of problems caused by the existing pouring cup without preheating function, such as thermal stress cracks, too fast cooling of molten metal, slag adhesion, etc. The design of the flame-retardant insulation sleeve can also maintain the temperature of the molten metal, reduce the temperature gradient, and reduce the incidence of casting defects.

[0016] A clampable filter structure is set at the outlet of the pouring cup body, which is convenient for replacement and cleaning, improving the efficiency of daily cleaning, thereby improving production efficiency and casting quality. In addition, the insulation sleeve is fixed by a clamp, which is convenient for installation, disassembly and maintenance.

[0017] The annular protrusion not only helps to install the flame retardant insulation sleeve, but also limits its position, which helps to improve the stability of the flame retardant insulation sleeve clamp fixation; moreover, the protrusion itself can also act as a reinforcing rib to improve the strength of the pouring cup body; in addition, this protrusion is also used as a mounting seat when the pouring cup body is installed in the mold or casting pipe, thereby improving its installation stability.

[0022] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0023] Figure 1 to Figure 2 The utility model is shown to involve a specific implementation scheme of a clamp-type pouring cup for casting. The pouring cup body 1 is made of high-quality refractory material and has an overall trumpet-shaped structure with a larger diameter at the inlet end and a smaller diameter at the outlet end, so as to facilitate the smooth transition and flow of the molten metal.

[0024] A layer of stirrup wire mesh 11 is designed inside the pouring cup body 1. The pouring cup body 1 is formed in one piece by the stirrup wire mesh 11 and the pouring cup body 1, which effectively enhances the structural stability of the pouring cup body 1 when subjected to the impact of high-temperature and high-pressure molten metal, has higher toughness and strength, and prevents the pouring cup from deforming or breaking under high-temperature working conditions. At the same time, the stirrup wire mesh 11 has good thermal conductivity and can assist the pouring cup in quickly and evenly preheating when the electric heating wire mesh 4 is working.

[0025] The outside of the pouring cup body 1 is wrapped with a flame retardant insulation sleeve 2, which is made of asbestos material and has excellent thermal insulation and flame retardant properties, and can ensure safety in a high-temperature casting environment.

[0026] An electric heating wire mesh 4 is embedded in the insulation sleeve. After the external power supply is turned on, the pouring cup can be effectively preheated and kept warm, which effectively solves various problems caused by the traditional pouring cup without preheating function, such as thermal stress cracks, too fast cooling of molten metal, slag adhesion, etc.

[0027] A holder 13 structure is designed on the outside of the outlet end of the pouring cup body 1, and a detachable filter 5 assembly is installed here. The filter 5 is connected to the adapter buckle 51 on the holder 13, which realizes convenient installation and disassembly, and is convenient for daily cleaning and replacement. In this way, the cleaning efficiency is effectively improved, thereby improving the casting quality and the efficiency of the pouring operation.

[0028] In addition, a ring-shaped protrusion 12 structure is specially added to the outer side of the pouring cup body 1 near the outlet end. On the one hand, the protrusion 12 serves as a limit support point when the flame retardant insulation sleeve 2 is installed. The insulation sleeve is fastened to the protrusion 12 through the clamp 3, ensuring the stability of the insulation sleeve installation; on the other hand, the protrusion 12 structure itself also plays a role in strengthening the strength of the pouring cup body 1. In addition, the protrusion 12 can also serve as a mounting seat when the pouring cup is connected to the mold or the pouring pipe, which increases the firmness of the installation.

[0029] In short, this clamp-type pouring cup for casting has been comprehensively optimized and innovated in structural design and function, which not only improves the safety of the casting process and the quality of castings, but also greatly improves production efficiency and meets the needs of modern precision casting technology.
