Because the movable members in article construction decision liftout attachment and mould is after pushing out product, ejecting of mould collides when matched moulds resets with movable members, causing cannot matched moulds smoothly, therefore mould needs reposition first is installed, during to reach reset, liftout attachment and movable members do not collide.At present, have several as follows at Making mold circle reposition first: 1. spring reposition first, it is that spring is directly contained on return bar, and this mechanism structure is simple, but spring must have enough elastic force, if after camber of spring inefficacy, and very easily mold damage.2. excellent power glue formula reposition first, it installs excellent power glue under utilizing return pin, thimble ejection mechanism can first be resetted a bit of distance, when ejecting mechanism is positioned on breaking face, bump against cover half face for ejecting mechanism when making matched moulds is unlikely, utilize the elasticity of excellent power glue to make ejecting mechanism can a bit of distance of first return.This mechanism structure is simple, easy for installation, but when resetting, safety coefficient is lower, very easily breaks mould.3. wedge block reposition first, when it is matched moulds, the guide runner that the return bar be fixed on cover half is first encountered on wedge block and push rod fixed head horizontally slips.Because wedge block two sides is equipped with 45 degree of inclined-planes, under return bar impetus, a direction moves right, and when the opposing party makes again push rod fix, the revert action of push rod terminates.The return Time dependent of push rod is in the length of return pin, and therefore plate produces revert action together with push rod, and the push rod being enough to generation is interfered when the length of 45 degree of inclined-plane return pins of the inclined-plane total detachment wedge block of return bar first exits the position of interference.This mechanism needs to ensure that the return part of mould does not interfere when resetting, but mould structure is complicated, there is the defect that stroke that push rod first returns is less simultaneously.In order to overcome the deficiency of above-mentioned reposition first, I am in conjunction with production line Design and manufacture experience for many years, and spy provides following a kind of reposition first to overcome the problems referred to above.
Summary of the invention
The present invention is to provide oscillating rod type spring and first resets mold mechanism, that oscillating rod type spring first resets mold mechanism as shown in the figure, it is as under type realization: after die sinking, in ejection process, fork (21) promotes push rod (18) and is released simultaneously together with goods (16) by thread core (17).When continuing to release, the 3rd guide pillar (6) is obstructed, promoting projection (27) by means of lining (19) forces fork (21) to swing, its fork (21) end face is made to depart from the state withstanding push rod (18), now, under the first spring (28) effect, push rod (18) is resetted; So just, thread core (17) can be loaded.During matched moulds, because the 3rd guide pillar (6) makes ejecting mechanism reset, in reseting procedure, after being reset to certain distance, projection (27) enters the concave station of fork (21) under the effect of the second spring (23), simultaneously fork (21) swings to mold center under the promotion on the 3rd spring (29) and top cap (2), finally resets in operating position.Oscillating rod type spring first resets mold mechanism, its beneficial effect is: when it is of value to the product molding with inserts, independent detent mechanism is not set in a mold, decrease processing link, its homing action is solid and reliable, it is of value to die cast metal mould and plastic injection mould, after die sinking pushing out product, its ejecting mechanism is resetted prior to other movable members, ensure that ejecting mechanism does not collide with other movable members, effectively prevent the effect that mould is not damaged in process of production; Simultaneously it manufacture, install, debug, keep in repair very convenient.Oscillating rod type spring first resets mold mechanism, solves spring reposition first, after camber of spring lost efficacy, and the problem of mold damage.Solve excellent power glue formula reposition first, during
