Problems solved by technology

The hard mold cannot be demolded at one time, and the method of decomposing and demoulding is required
Because the shape of the walnut slices is irregular, it is impossible to make multiple decompositions and multiple smooth butt joints
It is also impossible to produce two identical works, let alone realize industrialized production

Embodiment 1

[0012] Embodiment 1. The present invention is completed by a rotatable master mold and a well-proportioned slurry. First, a master mold is made. The master mold is a shell separated from the left and right by the center line, and separated from the left and right by the center line The two shells of the two shells are combined to form a complete shell, and the inner size and shape of the complete shell are the size and shape of the model to be made; the slurry is composed of waste paper pulp, gypsum, and cement, according to the weight The ratio of parts ratio waste paper pulp: gypsum: cement = 1.5: 1.2: 0.75 to prepare the slurry; pour the above-mentioned prepared slurry into the master mold, install the master mold on the high-speed rotating device, and rotate at a speed greater than 1000 Rotate the master model at a speed of 1 / min. After rotating for 1 minute, the required model is basically shaped and then stop rotating; remove the master model, open the master model, take ...

Embodiment 2

[0014] Embodiment 2, first make a master mold, the master mold is a shell separated left and right by the center line, and the two shells separated left and right by the center line are combined to form a complete shell, and the inner dimensions of the complete shell And the internal shape is the size and shape of the model that needs to be made; mix the slurry, the slurry is made up of waste paper pulp, gypsum, cement, and the ratio of waste paper pulp by weight: gypsum: cement=3: 2.5: 2. Prepare the slurry; pour the above-mentioned prepared slurry into the master mold, install the master mold on a high-speed rotating device, and rotate the master mold at a speed greater than 1000 rpm. After rotating for 5 minutes, the required model basically stops Rotate; take off the master mold, open the master mold, take out the shaped model, dry or dry naturally to get the desired model.

Embodiment 3

[0015] Embodiment 3, first make a master mold, the master mold is a shell separated left and right by the center line, and the two shells separated left and right by the center line are combined to form a complete shell, and the inner dimensions of the complete shell And the internal shape is the size and shape of the model that needs to be made; mix the slurry, the slurry is made up of waste paper pulp, gypsum, cement, and the ratio of waste paper pulp by weight: gypsum: cement=1: 0.75: 0.5. Prepare the slurry; pour the above-mentioned prepared slurry into the master mold, install the master mold on a high-speed rotating device, and rotate the master mold at a speed greater than 1000 rpm. After rotating for 3 minutes, the required model basically stops Rotate; take off the master mold, open the master mold, take out the shaped model, dry or dry naturally to get the desired model.

Abstract

The invention relates to a method for manufacturing an artware model, in particular to a method for manufacturing a walnut artware model. The method comprises the following steps of: manufacturing a female die, wherein the female die consists of left and right shells separated at the central line, and the size and the shape in the combined female die are those of the model to be manufactured; preparing slurry from waste paper pulp, gypsum and cement in a weight part ratio of (1-3): (0.5-2.5): (0.2-2); pouring the prepared slurry into the female die, and rotating the female die at the rotating speed of more than 1,000 revolutions per minute; and opening the female die after the female die rotates for 1 to 5 minutes, taking out the sized model, and drying or naturally airing the sized model to obtain the required model. The paper pulp can enhance the toughness of the model, the cement can increase the hardness of the model and the gypsum can be quickly sized, so the manufactured model is a hollow model and is lighter, and the problems that the model is difficultly manufactured in the walnut artware industry and the dimension is difficultly ensured when a plurality of models of products with the same shape are solved.

Description

technical field [0001] The invention relates to a method for making a handicraft model, in particular to a method for making a walnut handicraft model. Background technique [0002] Craft products have a long cultural history in our country, reflecting our culture, civilization and progress. It has collection value and ornamental value. Traditional handicrafts include root carvings, wood carvings, clay sculptures, eggshell carvings, etc. People now also have handicrafts made of pecan slices glued together. This handicraft product sticking up with hickory slices uses a hard mold, and can only be made with a straight plane and a semi-arc surface, such as a circular gourd shape. The hard mold cannot be demolded at one time, and the method of decomposing and demoulding is required. Because the shape of the walnut slices is irregular, it cannot be decomposed many times and connected smoothly many times. Also can't produce two identical works, more can't realize industrialized...
