Abstract

The invention discloses a modeling mould preparation method based on the paraffin characteristics, and paraffin for mould preparation. The preparation method comprises the following steps: (1) weighing a proper amount of wax, placing the paraffin in a crucible, melting the paraffin, pressing the molten paraffin into blocks by using a mould according to the volume of the mould, and cooling the paraffin blocks; (2) designing the three-dimensional graphs according to the CAD two-dimensional graphs of a required product; (3) performing automatic route planning by using software, carrying out processing imitation, processing the paraffin rectangular blocks by a milling bed into the required shape; (4) drilling holes in the blocks by a drilling bed so as to obtain the required V-process moulds; (5) after the V-process moulds are used, placing the moulds and the waste paraffin scraps generated during the process of milling bed processing into a special paraffin container, melting the paraffin, repeating the step (1), and rapidly manufacturing V-process moulds in different shapes in sequence. The prepared paraffin moulds can be recycled, thus the production cost is reduced, the space occupied by the waste moulds is saved, and the utilization rate of factory is increased.

Description
