Choosing uses cylinder ejector, and when injection molding machine molds state, melting sizing material enters hot sprue bushing 32 by hot runner system 3, melts
Sizing material is entered by the second flow channel 422 that the first flow 22 of 2 bottom of sliding block is formed with oblique top head 42 in cavity, at this time workpiece
6 link together with first flow 22 and second flow channel 422, and after 6 pressurize cooled and solidified of workpiece, mold die sinking, inclined guide pillar 5 exists
Under the action of mould opening force, after so that sliding block 2 is moved out disengaging first flow 22 and 422 certain safe distance of second flow channel, oblique top
First 42 and angle ejector rod 44 moved out under the ejection force effect of oil cylinder, the break away from moulds type in the case where ejecting force effect of workpiece 6 at this time
Chamber then can be by oil cylinder by 44 return of oblique top head 42 and angle ejector rod to take out workpiece 6, and is driven by inclined guide pillar 5
2 return of sliding block, mold clamping start the production of next product.
