[0002] In order to increase the realistic feeling of craft paintings, people have adopted a variety of different craft methods to make three-dimensional craft paintings, but the effect is ideal for three-dimensional paintings made by the method of blistering. Draw a picture on the sheet, then put it on the three-dimensional mold to spread it flat, and then heat it to soften it, then absorb it through vacuum equipment, and form a three-dimensional pattern after cooling. The material near the edge outside the middle pattern is also pulled into the mold, so that the edge line of the produced three-dimensional part does not overlap with the edge line of the pattern, and there is movement, which affects the accuracy of the protrusion. In addition, due to the softening of the blister material after heating The stretchability is not high. When encountering some deep concave-convex parts, the hard plastic sheet cannot completely fill the entire concave-convex parts, which seriously affects the fidelity of the three-dimensional pattern.

Embodiment Construction
[0014] Now describe this three-dimensional picture production process in detail. Its process steps are as follows:
[0015] a. On one side of the soft elastic film, make such figure 1 As shown in the pattern, the patterned film is spread on a base film, and the softness and elasticity of the base film are lower than that of the painting film;
[0016] b. Prepare the physical three-dimensional mold of the pattern;
[0017] c. Use a plastic welding machine to weld the two films around the edges of the pattern to produce such figure 1 The welded edge 1 shown in , while forming a closed cavity;
[0018] c. Open a small hole at the bottom mold of the closed chamber, inject a certain amount of solidifiable liquid glue into the closed chamber through the small hole, the film will expand, and then close the small hole, because the patterned film is better than the bottom film More soft and elastic, so as to ensure that the protrusion after injection mainly occurs on one side of th...

The invention discloses a method for manufacturing a three-dimensional handicraft pictures, which comprising the following steps: 1) making patterns on an elastic film; 2) laying the patterned elasticfilm on another film; 3) welding the upper and lower films along the peripheries of the patterns to form a sealed chamber; 4) injecting coagulable liquid glue into the chamber; 5) press forming the patterns after the glue injecting into shape with a mould, and after the liquid glue is coagulated, drawing the mould to obtain the three-dimensional handicraft picture. The method has the advantages that: the precision of the edges of raised patterns is high; the three-dimensional handicraft pictures are quite vivid; the surface configuration has an real object effect; and the fineness of the three-dimensional handicraft pictures is improved.
