Summary of the invention
The present invention provides the mould that secondary is released, it is to realize like this, after the mould active and inactive mold is opened, goods are moved dynamic model on one side with the action of mould dynamic model part, injector knock-pin promotion ejector retainner plate this moment (14) drives push rod (19) promotion push piece plate (20) goods (5) is deviate from from the core (6) on mould dynamic model one side, though goods have been deviate from from core, but goods are still stayed in the die cavity of push piece plate (20), it is up that this moment, the injector push rod continued promotion ejector retainner plate (14), at this moment the inclined-plane that is installed in the slide block (16) on the ejector retainner plate (14) contacts with the inclined-plane of baroclinic block (17) on being installed in moving platen (10), force slide block (16) in mould, to slide, when the hole on the slide block and push rod (19) when contacting, push rod (19) just enters that (annotate: the bore dia on the slide block must be greater than rod diameter in the hole of slide block (16), so that push rod enters in the slider bore smoothly), at this moment the injector knock-pin continues to release, because push rod (19) is fallen into and has been eliminated release power in the slider bore, therefore push piece plate (20) no longer moves, ejector retainner plate only promotes thimble (22) action, so from the die cavity of push piece plate (20) outside the launch mode, goods (5) drop out outside the mould by deadweight thimble (22) goods (5).The mould that secondary is released, it solved since the die sinking initial stage mechanism can not move at once, be trapped in cover half one side after the goods die sinking, the difficult problem that goods can't be deviate from.Solved the easy stuck slide block of mould and push rod, its push rod has been fractureed, the problem of mold damage.Solved because after once releasing, dynamic model continues to make its finally demould mechanism action in the process of die sinking; push rod will be released in the driven model cavity of goods; the spring that is installed on the mould contacts all the time with the dynamic model die cavity, and pull bar influence resets, and mould groundwork part is impaired technical barrier easily.The mould that secondary is released, it is characterized in that: cover half backing plate (1) and solid plate (7) are fastenedly connected with screw (2), the Kong Zhonghou that sprue bush (21) is installed in locating ring (3) is fastened on the cover half backing plate (1) with screw again, core (6) uses moving platen (10) to compress and be fastenedly connected with screw with moving platen (9) matched in clearance again, push piece plate (20) connects with push rod (19), return bar (8) and thimble (22) are installed in uses thimble pressing plate (14) to compress and fastening with screw again on the ejector retainner plate (12), slide block (16) is installed in the t shape groove of thimble pressing plate (14) and becomes to be slidingly matched, spring (18) is installed between ejector retainner plate (12) and the slide block (16), the Kong Zhonghou that baroclinic block (17) is installed in moving platen (10) uses screw fastening again, support plate (23) and dynamic model backing plate (15) are fastenedly connected with screw, and moving platen (9) support plate (23) is fastenedly connected with screw (11).
Description of drawings
The present invention is further described below in conjunction with accompanying drawing
