Abstract
Description
Technical Field
[0001] The utility model relates to a casting coating parameter confirmation structure, belonging to the technical field of auxiliary processing equipment used in the casting industry. Background Art
[0002] Sand mold is a tool used to cast metal in casting. It is a mold with a certain shape, size, quality and surface roughness made by a model or sample. Sand core is a sand mold used to form a complex internal shape, usually used to make holes and protrusions in hollow parts. Sand mold is mainly used to make the external shape of castings, usually used to make some castings with relatively simple shapes and relatively uniform flow conditions. Sand core is used for hollow parts such as coolers, intake pipes, exhaust pipes, cylinder heads, radiators, etc., and its uses and properties are different from sand molds. In the casting production process, the quality of the working surface of the sand mold or sand core that is in direct contact with the molten metal has a very important influence on the quality of the casting, and applying coatings on the working surface of the sand mold or sand core is the most economical and effective way to improve its quality.
[0003] Casting coatings are casting auxiliary materials that cover the surface of the core during the casting process to improve its surface fire resistance, chemical stability, resistance to molten metal erosion, resistance to sand adhesion and other properties. Casting coatings can be made into slurry, paste or powder, and applied to the surface of the core by spraying, brushing, dipping, flowing and other methods. In order to ensure the appearance quality of the casting and give full play to the best performance of the coating, we need to choose the appropriate coating density and coating layer thickness when applying the coating. Generally speaking, the density of the coating and the thickness of the coating layer are set according to the experience of the operator, which often causes certain product scrapping and waste in the early stage of casting production. Therefore, there is an urgent need for a mechanism that can simply determine the density and coating layer thickness of casting coatings. Utility Model Content
[0004] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.
[0005] In view of the problems and shortcomings in the prior art, the utility model aims to provide a casting coating parameter confirmation structure, which arranges multiple test mud core groups along the inner wall of the sand mold shell, and the diameter of each test mud core group is different. Each test mud core group includes multiple mud core cavities, and casting coatings of different thicknesses and densities are applied on the protruding end surfaces of the mud core cavities. After the test, the optimal coating density and coating layer thickness can be confirmed. This solves the problems in the above-mentioned background technology.
[0006] To achieve the above object, the present utility model provides the following technical solutions: It includes a sand mold shell, and the sand mold shell is provided with a cylindrical structure with one end open and the other end closed. At least one group of test core groups are connected along the circumferential direction on the inner side wall of the sand mold shell. Each group of the test core groups includes a plurality of core cavities. One end of each core cavity is embedded and connected to the inner side wall of the sand mold shell, and the other end protrudes from the inner side wall surface of the sand mold shell.
[0007] Preferably, the test core group includes a first core group, a second core group, and a third core group arranged vertically. The test core group is set to three groups, namely the first core group, the second core group, and the third core group, and they are connected and installed vertically on the inner side wall of the sand mold shell.
[0008] Preferably, each of the first core group, the second core group, and the third core group contains six of the core cavities. The first core group, the second core group, and the third core group each include six core cavities, that is, a total of eighteen core cavities are embedded and installed on the inner side wall of the sand mold shell, and the core cavities are set to a cylindrical structure.
[0009] Preferably, the diameters of the core cavities in the first core group, the second core group, and the third core group are different. That is, the six core cavities included in each group of test core groups have the same diameter, but the core cavities in the first core group, the core cavities in the second core group, and the core cavities in the third core group have different diameters.
[0010] Preferably, the density and thickness of the casting coating applied to the protruding end surface of each core cavity are different. Since a total of eighteen core cavities are arranged along the circumferential direction on the inner side wall of the sand mold shell, different densities and thicknesses of casting coatings are applied to the protruding end surfaces of these core cavities, which is convenient for later selecting the most suitable density and coating layer thickness of the casting coating.
[0011] Compared with the prior art, the beneficial effects of the present utility model are:
[0012] The utility model has the characteristics of simple structure and convenient use. It includes a sand mold shell with a cylindrical structure that is open at one end and closed at the other end. Along the circumferential direction on the inner side wall of the sand mold shell, three groups of test core groups are connected. Each core group includes six core cavities, that is, a total of eighteen core cavities are provided. The core cavities are set as a cylindrical structure, and one end of each core cavity is embedded and connected in the inner side wall of the sand mold shell, while the other end protrudes from the inner side wall surface of the sand mold shell. Before the test, casting coatings with different densities and thicknesses are applied to the protruding end surfaces of the core cavities. The molten metal is poured into the sand mold shell from the open end. After cooling, the surface quality of the eighteen core cavities is inspected respectively, and the cavity with the best surface quality is selected, so as to obtain the best density of the coating and the thickness of the coating layer, greatly reducing the product scrapping and waste caused by casting production, and effectively reducing the production cost.

At least one group of test core groups 2 is connected along the circumferential direction on the inner side wall of the sand mold outer shell 1. Each group of test core groups 2 includes a plurality of core cavities. One end of the core cavity is embedded and connected to the inner side wall of the sand mold outer shell 1, and the other end protrudes from the inner side wall surface of the sand mold outer shell 1.
