Abstract

The invention discloses a flow guide ring casting numerical control machining mold and a manufacturing method thereof. The mold is divided into a flow guide ring casting mold and a flow guide ring casting core box mold, an outer cylinder face of a cylinder base of a wood frame of the flow guide ring casting mold is formed by uniform arranging of multiple rectangular plates A, a gap exists betweentwo adjacent rectangular plates A, an inner cylinder face of the wood frame of the flow guide ring casting mold is formed through uniform arranging of multiple rectangular plates B, a gap exists between two adjacent rectangular plates B, other portions of the wood frame of the flow guide ring casting mold are formed through splicing of multiple forming wood plates or wood blocks, a skin covering layer is bonded with and covers the wood frame, through improving of a flow guide ring casting mold composite structure and improvement of a mold covering layer material formula, the adaptation capacity of the mold covering material to the production environment changes can be improved, the mold can be matched with a numerical control machine tool for fine repair machining of a mold product, and machining precision, quality and yield of the flow guide ring casting mold can be improved.

Description

technical field [0001] The invention relates to the production field of casting molds, in particular to a numerically controlled machining mold for a diversion ring casting and a manufacturing method thereof. Background technique [0002] With the continuous improvement of the production scale and production volume of foundry mold enterprises, as well as the continuous improvement and innovation of production technology, the problems of high turnover rate of technicians and faults in reserve forces in foundry mold enterprises have become increasingly prominent. Among them, how to reduce costs and improve Productivity and improving product quality have become the focus of attention. [0003] The traditional casting mold method is through manual drawing, manual cutting and manual assembly of the mold by technicians. The production efficiency of the product is low, the production cycle is long, the product accuracy is low (the size error value is ±2-3mm), and the outer surface ...
