Embodiment Construction

[0024] The manufacturing method of the reverse engraving three-dimensional head portrait of the present invention mainly includes the steps of preparing the head portrait, blank making and embossing, deep engraving, inverting the master mold, grouting and air extraction, condensation molding, coloring and filming, and the like. In this embodiment, a head portrait of a Buddha statue is used for specific description. First, according to the design requirements of the engraved head, use the existing carving technology to carve the three-dimensional head of the Buddha statue or directly use the existing three-dimensional head for backup. Next, make a piece of oil blank with an area larger than that of the solid head. The oil is made of finely carved hard oil, and the top surface of the blank is flattened; the oil is heated and softened, and the front of the spare three-dimensional head is pressed on the central position of the top surface of the blank. The three-dimensional head i...

Abstract

The invention discloses a reversely graved three-dimensional head portrait manufacturing method which comprises the steps of head portrait preparation, blank preparation, impression, deep graving and engraving, reverse female die manufacturing, grouting, air exhausting, condensation molding, coloring, coating and the like. The method specifically comprises the followings steps of: impressing a concave head portrait on an oil blank material; deepening the lines of the concave head portrait by using a graver, wherein the engraved lines are deepened by 3-8% compared with the original lines; manufacturing a model, injecting molding rubber in the model provided with the model, and inverting the female die of the head portrait; and injecting glass slurry for condensation molding after opening the female die, and coloring and coating the molded blank to obtain the finished product. The invention enables the concave head portrait to achieve the convex three-dimensional head portrait effect toward the direction opposite to the concave by using spatial fluctuations and human visual illusion through the methods of reversely graving the concave head portrait and deepening graving depth, and thus, the head portrait is life-like and vivid.

Description

【Technical field】 [0001] The invention relates to a method for making a three-dimensional head portrait, in particular to a method for making a reverse-engraved three-dimensional head portrait. 【Background technique】 [0002] Sculpture is a technique of digging out the shape to be shaped step by step by gradually subtracting waste from the carved object. The existing methods of making three-dimensional head portraits by engraving methods all use engraving tools to carve out concave-convex lines on the blank according to the design requirements of the head portrait, and construct a three-dimensional head portrait protruding outward. The form of this carved three-dimensional head portrait is single, and the spatial structure of the head portrait is a protruding three-dimensional solid space. The head portrait carved is not vivid and has weak appeal. 【Content of invention】 [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and prov...
