Abstract

Background. Body parts are the most common casting parts. A feature of the considered part of the axial piston pump cover is complex internal holes with a curved axis, having a common plane of entry into and exit from the part. Therefore, in order to obtain these body holes, various casting methods were simulated: sand casting, mold casting from cold-hardening mixtures, chill casting, investment casting, gasified casting to identify the technologically optimal variant of manufacturing complex holes. Purpose: obtaining a method for obtaining a blank part of an axial piston pump cover, in which it is possible to obtain internal holes with curved axes without using core boxes, liners and mechanical intervention.
Materials and methods. The complex design and technological features of the gray cast iron cover show the advantages and disadvantages of each of the casting methods. For sand casting, mold casting from coldhardening mixtures, chill casting, investment casting, gasification casting, 3D models were built taking into account allowances, overlaps, roughness and accuracy of castings.
Results. A comparison of technological processes of the considered casting methods and the time of mold production, personnel qualifications is made. The calculation of the utilization factor of the material has been made.
Conclusions. As a result of the study, it was revealed that the most optimal way to obtain castings with a complex internal configuration is casting into molds from cold-hardening mixtures. The analysis of the studies showed that the time spent on preparing the production of castings is less than for other casting methods, and the surface roughness and dimensional accuracy parameters are also lower than for other casting methods.
