Shape follow-up typecasting method for castings

Abstract

The invention relates to a shape follow-up typecasting method for castings in the technical field of casting. The specific process comprises the following steps: firstly producing standardized typecasting modules with the same length, width and thickness dimensions, and the standardized typecasting modules comprising a plurality of selectable common letter modules, Arabic numeral modules and common symbol modules; then composing casting information according to the typecasting information and positions of the castings, taking a bendable plastic plate having the same dimensions as a typecasting area, and bonding the corresponding typecasting modules on the surface of the plastic plate respectively according to the composed casting information; then seamlessly bonding the plastic plate bonded with the typecasting modules at a position needing typecasting, on the surface of a casting die, and integrally forming the plastic plate bonded with the typecasting modules, with the die; then placing the casting die in a sand box and carrying out fluid sand moulding, then opening the box, drawing the die, drawing the plastic plate bonded with the typecasting modules, with the die, and forming typecasting cavities at cavity positions corresponding to the typecasting modules; and then continuing the subsequent box closing, pouring, cooling and shake-out.

Description

technical field [0001] The invention relates to the field of casting technology, in particular to a casting method for conformal casting, which is used to form casting surface casting information. Background technique [0002] In the prior art, a foundry generally adopts a core box manufacturing process when manufacturing casting information on the surface of a casting. First, use the drawing software to create the appearance of the type core box, and process the type information 1 in the type core box 2 using a machine tool, such as figure 1 As shown, then make the casting sand core 3, such as figure 2 As shown, the casting sand core 3 is placed on the surface of the casting mold 4 required, as image 3 As shown, the quicksand molding and lifting are carried out at last, and finally a cavity with the shape of casting characters is formed, which is combined with the casting and poured at the same time. [0003] This manufacturing method of casting type has the following ...

AI Technical Summary

Problems solved by technology

[0003] This manufacturing method of casting type has the following deficiencies: the production cycle is long, and the labor cost of type mold making is high; Both need to make sand cores first, and then place the finished sand cores on the mold for modeling. The manufacturing process is cumbersome; The appearance quality of the casting part is poor, which affects the beauty of the casting
