Description

Technical Field

[0001] This utility model relates to the field of bottle cap mold technology, and in particular to a perfume bottle cap forming mold that is easy to remove. Background Technology

[0002] After the injection molding machine melts plastic granules, it injects them into the bottle cap cavity formed by the upper and lower molds. After cooling, the molded bottle cap is ejected from the lower mold cavity by the ejector pin set inside the lower mold, thus obtaining the desired bottle cap. Bottle cap production is generally mass production, that is, multiple bottle caps can be molded at one time in one mold. However, this mass production process may lead to existing perfume bottle cap molding molds generally having problems such as structural redundancy and low integration. In view of this, a perfume bottle cap molding mold that can solve the above problems and is easy to remove is proposed. Utility Model Content
