Pneumatic ejection mechanism is the compressed air is introduced into plastic parts and cosmetics cosmetics packaging hose production mould, the ejector demoulding of a plastic gear.
This although ejection device to set up the device of compressed air, compressed air channel and all kinds of pneumatic components, etc. , but because it is not using some mechanical parts, such as push, push the cosmetics packaging hose, push rod to push the plastic parts, such as to eliminate the associated with the transmission mechanism, thus make cosmetics cosmetics packaging hose production mould structure was greatly simplified, its core and concave die can use pneumatic ejection, and at the top of the mould at any position in the process of plastic parts.
In addition, this kind of mold release due to no ejection parts of molded parts strength, so to receive strength evenly in plastic parts, no ejection trace, plastic parts ejection deformation is small, after ejection mechanism can be set in motion, on either side of the fixed mould.
This specially for ejection device and deep cavity thin wall container, especially soft plastic plastic mold release.
