The invention discloses a mold-free machining method for a smaller contact surface type evanescent mode model. The method comprises the following steps that the evanescent type model with a smaller contact surface or supporting surface is selected as a to-be-machined model; the to-be-machined model is subjected to front-side machining according to a predetermined manner by adopting a mold-free modeling machine, and a semi-finished product to be machined model finished by the front-side machining is obtained; a machining pad is used as a support tool for mold-free machining, the lower end faceof the pad is consistent with the shape of the front face of the to-be-machined model, the upper end face of the pad is of a plane structure, and a matching gap is reserved between the pad and the front face contact face of the to-be-machined model; the front face of the to-be-machined model I is placed on the pad, and the back face of the to-be-machined model is machined according to the predetermined manner by virtue of the support of the pad to obtain a finished product model. According to the mold-free machining model for the evanescent mode with the small contact surface, the problem thatthe back surface is difficult to machine is well solved by using the support of the pad, and therefore, the mold-free machining method of the evanescent mode enables the machined model type to be more.
Description
technical field [0001] The invention relates to the field of die-free processing of casting, in particular to a die-less processing method of a lost foam model with a small contact surface, and is especially suitable for a die-free processing model of a lost foam model with a small contact surface. Background technique [0002] The moldless processing of the cast lost foam model is to divide the three-dimensional model, and use the moldless molding machine to cut the front and back sides (the first processing surface is the front side, and the second processing side is the back side), and the foam model is directly processed. . Sometimes when encountering a model that does not have a large contact surface on both the front and back sides, there is no large contact surface to support the model during reverse processing, which makes it difficult to process the reverse side of the model. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the...
