Embodiment 1

[0015] The method for making a mold with silica gel, the specific steps of the method are: 1) making a master mold, which is the basic shape of a shaped tin product, and is used to make a profiling; 2) making a profiling, the profiling is made through the master mold It is made by imprinting the pattern on the outer wall of the master mold on the inner wall of the mold sleeve; 3) Prepare the silica gel compound (that is, heat all the components to 250°C and then stir and mix), when the tin blank is placed in the mold sleeve, in The silica gel compound is filled in the gap between the two, so that the silica gel compound is covered on the outer wall of the tin billet; the silica gel compound is calculated in parts by mass, including 80-90 parts of silica gel and 0.5-2.5 parts of equine (2α, 27-ditrans-p-hydroxycinnamoyloxybetulinic acid).

Abstract

The invention belongs to the technical field of die preparation, and particularly relates to a method for manufacturing a die through silica gel. The method comprises the specific steps that 1, a female die is manufactured, i.e., the female die is in a basic shape of a formed tin product and is used for manufacturing a pattern die; 2, the pattern die is manufactured by printing patterns on the outer wall of the female die onto the inner wall of a die sleeve through the female die; and 3, silica gel compounds are prepared, and after a tin blank is put into the die sleeve, the interval between the tin blank and the die sleeve is filled with the silica gel compounds and the silica gel compounds are made to cover the outer wall of the tin blank, wherein the silica gel compounds comprise, by mass, 80-90 parts of the silica gel and 0.5-2.5 parts of paliurus ramosissimus. Compared with the prior art, the method for manufacturing the die through the silica gel is high in efficiency and large in production scale, the obtained tin product is smooth and clean in surface and free of parting surfaces, and neither reprocessing nor less processing is not needed.

Description

technical field [0001] The invention belongs to the technical field of mold preparation, and in particular relates to a method for making a mold with silica gel. Background technique [0002] China is rich in tin ore resources. Tin products are tin deep-processing products with high added value and have a good market prospect. The current proven tin reserves are more than 3 million tons, and China's refined tin production has leapt to the first place in the world, but my country's tin deep-processing products are few. Except for a small amount of craft products, there are currently only 76 tin products, and about 50% of tin is It is exported in the form of two primary products, refined tin and solder. Studying the forming of tin products is of great significance to improving the product structure of tin products in China and giving full play to the advantages of tin resources. Although the production of tin products in my country has a long history, the technology used is r...
