Embodiment Construction
[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0017] see figure 1 , in the embodiment of the present invention, the casting combined sand core assembly process, the steps are as follows:
[0018] (1) Prepare a flat plate first, the flat plate is made of cast iron or cast steel, and the size is 2000mm×2000mm;
[0019] (2) Connect the second tooling 2 to the plate with bolts, wherein the bolts are designed to be universal, so as to facilitate the sharing of different types of sand cores;
[0020] (3) The ...

The invention discloses a casting combined type sand core assembly process. A slab is prepared, a bolt used for a second tool is connected to the slab, then a bolt used for a third tool is connected to the second tool, and the bolts are universal type bolts. Vane sand cores to be assembled are assembled around the second tool by pieces. The third tool is replaced according to the sizes of the different sand cores, so that the sizes of the sand cores are convenient to control. According to the method, assembling of the complex sand cores by a worker is greatly convenient, the problem of size over-tolerance caused by the situation that sand core combining is not in place is solved effectively, and core assembling by the worker is convenient; and for a same casting, the labor intensity of core assembling by the worker is reduced by 90%, so that labor efficiency is improved, and the manufacturing cost of enterprises is reduced.
Description
technical field [0001] The invention relates to the field of sand cores, in particular to a casting combined sand core assembly process. Background technique [0002] The current commonly used diversion body and impeller sand core assembly process, due to the many blades of the sand core, the operation of the core assembly is inconvenient, and the size difference between the sand core and the sand core is large after the sand core is assembled, resulting in uneven thickness of the casting, increasing the The workload of casting finishing and grinding will greatly increase the production cost of castings. Contents of the invention [0003] The object of the present invention is to provide a casting combined sand core assembly process to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A casting combined sand core core assembly process, th...
