Embodiment 1

[0035] figure 1 Shown is the structural representation of the lower mold of a kind of mold that utilizes the material for mold preparation of the present invention, in the figure, mold core 2 is built-in and installed in the mold case 1, and the mold core 2 is provided with the mold of predetermined shape Cavity 3, the mold cavity 3 is used to accommodate the raw material and shape the raw material.

Embodiment 2

[0037] figure 2 Shown is the structural representation of another kind of mold that utilizes the material for mold preparation of the present invention, in the figure, the structure of mold is eight petals, and 1 is pressing plate, and 2 is heater, and 3 is mold core, and 4 is The mold end screw cap, 5 is the mold end gland, 6 is the raw material, 7 is the air inlet, 8 is the jacket, 9 is the heating jacket, and 10 is the base. Among them, the eight-petal mold is sealed by the jacket 8 to form a mold cavity. The mold can adopt inflation superplastic molding technology. When working, the heater 2 heats the mold core 3 and puts in the raw material 6 to start molding. After the molding is completed, the jacket 8 is released, and the eight-petal mold is separated, and the molded workpiece can be taken out.

[0038] The preparation material of the mold core of the mold shown in embodiment 1 and embodiment 2 can be at least one in pottery, gypsum and cement, in addition, can also ...

Embodiment 3

[0040] First sieve all the materials to separate the particles, and then formulate the mineral base and binder according to the following formula:

[0041] Mix black silicon carbide and other ingredients (including 44.9% by weight of alumina and 0.1% by weight of graphite) at a ratio of 1:1 (the ratio is calculated by weight, the same below) to form a mineral substrate; 60:15:10:5 : Mix alumina, water, fly ash, silica, hydraulic cement, boric acid and borax in a ratio of 6:1:3 to form a binder (water must be added first, and each ingredient is added one by one, and constantly stirred carefully) ; Then mix the mineral base, binder and steel fiber in a ratio of 56:4:40, pour it into the steel mold after mixing, and prevent air bubbles when pouring the mold. After pouring the mold, use a press to compact it with a pressure of 10 tons, and after holding the pressure for 5 minutes, the mold is demoulded to generate a blank. Allow the blank to fix in air for 2 hours. Then carry ou...

Abstract

The invention provides a material used for a mould, a mould and a mould preparation method. The material used for the mould consists of at least one of ceramic, gypsum and cement. The material used for the mould can be utilized for effectively preparing the mould and has the advantages of low cost, short production period and the like, and the problems of single mould preparation material, high preparation cost, long preparation period and the like in the prior art can be solved, and the development and the application of a superplastic forming technology can be facilitated.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular, to a material for a mould, a mould, and a method for preparing the mould. Background technique [0002] Since the 1960s, superplastic molding technology has become popular in developed countries such as Europe and the United States, and has attracted the attention and research of a large number of scholars. However, in the prior art, steel is generally used as the material for superplastic forming molds, and the price is relatively high, and the production cycle of the mold is relatively long, and in some extreme cases, a set of molds may be scrapped when producing one product. , causing great waste, and the greater the number of molds required, the greater the investment, which seriously affects the development and application of superplastic molding technology. [0003] Therefore, the current mold technology needs to be further improved. Contents of the invention [0004] The ...
