Silica gel is a porous substance with different particle sizes formed by proper dehydration of silicic acid gel. It has an open porous structure and can adsorb many substances. It is a good desiccant, adsorbent and catalyst carrier. A large part of silica gel products are produced by mold shaping. Silicone has a relatively soft texture and needs to be ejected from the mold by an ejection mechanism after shaping.

[0003] The existing silicone product extruder lacks cooling effect when extruding silicone products, resulting in slow molding of silicone products, and some silicone will stick to the mold. For example, the multi-stage ejection mechanism of the silicone product extruder with application number CN202120878703.X lacks cooling equipment, resulting in slow molding of silicone products, and it is necessary to manually remove the top plate before ejecting the material. It cannot work automatically, which affects production efficiency. For this reason, this application proposes an ejection mechanism of a silicone product extruder to solve this problem.
