Example 1
Firstly, dividing mold curved surface data of a three-dimensional mold of the mold to be molded into a mold, wherein a track warp surface and a track weft surface are respectively equidistant to the interior of the mold, and the track weft surface is arranged below the track warp surface; then, generating a plurality of track warps on the track warp surface, and sequentially calculating all the track warps to generate a forming motion control code of each track warp; generating a plurality of track wefts on the track weft surface, and sequentially calculating all the track wefts to generate a molding motion control code of each track weft; inputting all the warp yarn and weft yarn forming motion control code data of the track into a numerical control device, and sequentially folding all weft yarns and warp yarns consistent with the warp yarn and weft yarn tracks by the numerical control device, wherein the equidistant distance of the warp yarn surfaces of the track is equal to the radius of the warp yarn, and the distance between the warp yarn surfaces of the track and the weft yarn surfaces of the track is equal to the radius of the weft yarn plus the radius of the warp yarn; accurately placing all warp threads and weft threads on a lower mold frame according to the coordinates of warps and wefts of the model, wherein the weft threads are arranged on the lower layer, and the warp threads are arranged on the upper layer to respectively form a reticular thread mold layer; the upper and lower mesh wire mold layers are then filled or joined by dipping or welding to form a thermoplastic mold having mold strength.
Inputting all the warp and weft G code data (G code is a motion control code which can be identified by index control equipment or a robot) by using a numerical control bending machine, sequentially folding all weft wires and warp wires consistent with the warp and weft tracks, accurately placing all the warp and weft wires on a lower die frame by using a manipulator according to the coordinates of the warp and weft of a model, arranging the weft wires on the lower layer and the warp wires on the upper layer, thus forming a reticular wire die, and connecting the upper layer and the lower layer of wires into a whole by dipping or welding to have enough strength so as to be used as a thermoplastic die.
The equidistant distance of the track meridian plane is the distance between two parallel curved surfaces, like the distance between two concentric spherical surfaces with different radii. The warp or weft is numbered in sequence by software, the warp or weft interval designs can be equal or unequal, and the user can automatically adjust the interval and the distribution quantity of the warp and the weft to achieve better supporting effect and reduce cost.
Example 2
