[0002] The automobile engine cylinder head bolt precision forming mold is a mold for processing the automobile engine cylinder head bolts. The automobile engine cylinder head is installed on the cylinder body, sealing the cylinder from the top and forming a combustion chamber. It is often in contact with high-temperature and high-pressure gas, so it is subject to a large thermal load and mechanical load. Therefore, the cylinder head bolts need to play a firm and high-temperature resistant effect;

[0003] For example, the precision forming mold for automobile engine cylinder head bolts with patent application number CN201720756635.3 includes a mold base, and a feeding area, a molding area and a discharging area are sequentially arranged on the plane of the mold base; the feeding area is provided with an introduction tooth, the molding area is provided with a mechanical tooth, and the discharging area is provided with a discharging tooth. The feeding area is inclined upward, the molding area is horizontally arranged, and the discharging area is inclined downward. The length of the feeding area is greater than the sum of the lengths of the molding area and the discharging area. The downward inclination angle of the discharging area is greater than the upward inclination angle of the feeding area. The end of the discharging area is provided with a round tooth, and the discharging is performed through the round tooth.
