Abstract

The invention provides a method for fixing a cast hole embedded piece. The method comprises the following steps that the embedded piece (1) is selected or manufactured according to the dimension of a cast hole to be molded; and the embedded piece is fixed to a to-be-molded cast hole position (A) in a mould through an intermediate fixing piece, and a preset height is reserved for the embedded piece (1) outside the mould (3). The method for fixing the cast hole embedded piece aims at overcoming the shortcomings that in the prior art, machining of slender cast holes is high in difficulty, and quality is hard to control. According to the method for fixing the slender cast hole embedded piece, production and operation are easy and convenient, dimension control is accurate, and accordingly the overall quality of castings is improved significantly.

Description

technical field [0001] The invention relates to a fixing method, in particular to a fixing method of an embedded part in a slender casting hole. Background technique [0002] With the continuous progress of internal combustion engine technology, the technical requirements of internal combustion engine frame, end cover and other products, which are the core components of internal combustion engine, are also constantly improving. The difficulty of producing such products in the existing technology is mainly reflected in: complex inner cavity shape, small casting holes Many, high quality requirements. As one of the difficulties in the production of such castings, small casting holes are mainly reflected in the following aspects: (1) small hole diameter; (2) long hole length; (3) small amount of processing along the circumference; (4) small Most of the holes are located in the inner cavity, which is not easy to clean; (5) Small holes are not allowed to have sticky sand defects....
