Cut four pieces of paper into small strips and hold a gourd shape in your hand. (Modeling belongs to recycling, which is more troublesome to do. I suggest you buy a finished product of a treasure, because you use a precision lathe. The bowl is ordinary water, and the strips should be completely soaked, otherwise the following work will not be perfect;

After the strip is soaked, it is evenly attached to the surface of the champion, and one layer is enough. Stick them tightly, leaving no gaps and no sticking places;

Adhere to the second layer;

This is the second step after pasting 4 to 5 layers of white strips. Use kraft paper with a width of about 5cm, and paste it (wet both sides as much as possible);

Wrapped in kraft paper, it must be tight and seamless;

Touch it tightly with your hands;

Continue to wrap tightly, especially at the belly and navel, because that place is not perfect, needless to say, it is very tight;

After winding 6.7 layers, the left white A4 paper strip turns down;

Stick it with kraft paper and seal it;

Tighten the stirrup by hand. Complete;

Let it dry for an hour or two after pasting.

Second, the mold introduction:

Mold )( mújù) refers to various molds and tools used in industrial production, and the required products are obtained through injection molding, blow molding, extrusion, die casting or forging, melting and stamping. In short, molds are tools used to shape objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article by changing the physical state of the molding material. Known as the "mother of industry".

A tool for making a blank into a product with a specific shape and size under the action of external force. Widely used in stamping, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or cavity shape, and by applying the contour shape with cutting edge, the blank can be separated (punched) according to the contour shape. Applying the shape of the inner cavity can make the blank obtain the corresponding three-dimensional shape. Generally speaking, molds include a moving mold and a fixed mold (or a male mold and a female mold), which can be separated or combined. When parting, the parts are taken out, and when closing, the blank is injected into the mold cavity for molding. Die is a kind of precision tool with complex shape, which bears the bulging force of blank and requires high structural strength, stiffness, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important symbols of mechanical manufacturing level.
