Description

Technical Field

[0001] The utility model relates to the technical field of silicone mold demoulding, in particular to a demoulding device for inner and outer silicone molds for jewelry casting. Background Art

[0002] Silicone molds are special molds for making handicrafts. They are resistant to high temperatures, corrosion, and tearing, and have high simulation precision. They are now widely used in the production of artificial stone. Artificial stone, also known as imitation stone, is made by adding accelerators, thickeners and other polymer materials to environmentally friendly aggregates. It is formed after a series of processes such as stirring, injection molding, hardening and demoulding. It has the characteristics of fireproofing, waterproofing, acid and alkali resistance, pollution resistance, non-toxicity, odorlessness, strong adhesion, and no fading. It also has the advantages of simple construction and time saving.

[0003] However, in the prior art, after the jewelry product is formed, the silicone mold is usually cut manually, and then the jewelry product in the silicone mold is manually dug out, which is not only inefficient but also labor-intensive. Therefore, we propose a jewelry casting inner and outer silicone mold demoulding device. Utility Model Content

[0010] The beneficial effects of the utility model are:

[0011] 1. Fix the silicone mold by setting a fixing piece, and use the third electric push rod to drive the cutting plate to cut the silicone mold, exposing the jewelry inside, and then use the extrusion rod to hold the inner mold in the middle, and then use the extrusion ring to squeeze out the jewelry, so as to separate the jewelry product from the inner mold and the outer mold, replacing manual operation, which is efficient and practical;

[0012] 2.
