AI Technical Summary
Setting up a separate drive component in existing injection molds increases the complexity of the mold structure and manufacturing cost, and poses a risk of failure, affecting the ejection process of the molded parts.
The system employs components such as an ejector column, a fixed top support plate, a limit slide plate, and a return spring. The moving mold is driven by a cylinder, which in turn drives the inner sliding seat and ejector pin to eject the molded part simultaneously, thus achieving automatic demolding of the molded part. This simplifies the mold structure and reduces the risk of failure.
It enables convenient demolding of molded parts, reduces the complexity of mold structure and manufacturing cost, improves production efficiency, and reduces the risk of failure.
