The comb teeth 2 are frustum-shaped structures, and one ends of the comb teeth, which are opposite to the connecting rods, are provided with spherical structures 21.

The manufacturing process of the hollow comb comprises the following steps:

1) designing the comb style: the style of the comb is designed by utilizing the Beijing carved piece, the style of the designed comb is shown in figure 4, and the style of the designed comb is provided with a structural line for connecting all comb teeth. The broach is frustum column structure, and the one end relative with the connecting rod of broach is provided with globular structure.

2) Manufacturing a comb tooth structural part model: the designed comb style is guided in, and a comb tooth structure model is manufactured by Beijing engraving software and comprises a plurality of comb teeth and a connecting rod for connecting the comb teeth. The designed comb tooth structural part model comprises the steps of determining the size and the thickness of the comb, the number of comb teeth, the width of the comb teeth, the tooth space and the like.

3) Manufacturing an aluminum die: the designed comb tooth structural part model is guided into a Beijing finishing impression programming module to be programmed, corresponding cutting parameters are set according to different machine equipment in the programming process of the feeding speed and the cutting depth, the position of a wax injection water gap is required to be engraved, and in addition, two corresponding guide pillar holes are required to be engraved on a female die due to the fact that the female die is provided with a front side female die and a back side female die, so that the front side female die and the back side female die can just correspond to each other. And (4) guiding the programmed program into a CNC machining center, assembling the aluminum plate, and engraving to obtain the aluminum plate.

4) Manufacturing a wax mould: the liquid wax is injected into an aluminum mold to form a wax pattern.

5) Manufacturing a comb tooth structural member: planting a plurality of wax molds on a wax tree, then placing the wax tree in a steel cylinder, injecting a gypsum slurry filler into the steel cylinder, standing for 40min, placing the steel cylinder in an electric furnace after the gypsum slurry filler is solidified, firstly heating the steel cylinder to 50 ℃ to discharge water in the gypsum slurry, then heating to 100 ℃ to melt the wax, then heating to 300 ℃ to discharge the wax for about 120min, then heating to 500 ℃ to discharge the wax completely for about 150min, and then heating to 700 ℃ to burn the gypsum till the gypsum is completely solidified and has certain hardness. And then injecting silver water for manufacturing the comb teeth into the steel cylinder, filling the silver water into a space formed after the wax film flows out, and removing the gypsum filler to obtain a plurality of comb tooth structural members.

6) Designing a comb handle model: measuring the size of the comb tooth structural member obtained in the step 5), and designing a comb handle model by using Beijing engraving software according to the size.
