Problems solved by technology
[0004] However, for large-sized planar products, such as coin-style necklace pendants, due to the large planar area, the existing lost-wax inversion process will cause some surface unevenness caused by tiny air bubbles on the product after inversion. Small flaws, which affect the overall quality, can only be polished off a certain thickness in the following process to eliminate the flaws, which increases the cost and consumes a lot of manpower

Abstract
The invention discloses a lost wax mold pouring process for metal jewelries. The process comprises the following steps: connecting a wax pipe to a wax core, and forming an air pouring channel communicating with the bottom of a cavity in a plaster mold after wax loss of a wax tree, so that when molten metal is injected into the cavity of the plaster mold, air at the bottom of the cavity can be exhausted along the air pouring channel, thus, a large amount of air reversely exhausted from the cavity is reduced, a large number of tiny bubbles are prevented from being formed in the molten metal injected later, the problem that the surfaces of the jewelry parts are uneven is solved, the labor cost of later surface treatment is reduced, and the consumption of raw materials is reduced.
Description
Technical field[0001]The invention relates to the technical field of jewelry manufacturing, in particular to a lost wax inverted mold process for metal jewelry.Background technique[0002]With the rapid development of my country’s economy and metallurgical industry, and the rise of new industries such as jewelry and precious metal jewelry, people are more and more interested in precious metal jewelry, and the requirements for the exquisiteness of precious metal jewelry are getting higher and higher. Therefore, manufacturers are constantly developing new precious metal jewelry processing techniques to produce more exquisite precious metal jewelry to meet people's pursuit.[0003]However, in the existing lost wax inverting process, when the mold is inverted, that is, when the molten metal is injected into the cavity of the plaster mold, the molten metal first reaches the bottom of the cavity, and the molten metal squeezes the air at the bottom of the cavity. The gas at the bottom of the c...
