Description

The little push rod secondary ejecting mechanism of injection mold
Technical field
The utility model relates to the little push rod secondary ejecting mechanism of a kind of injection mold, belongs to the mould of plastics field.
Background technology
When adopting mould of plastics to produce the smallclothes plastic products, because the volume of goods is smaller, the muscle that is shaped with on the goods and the gap between the muscle are just very little, therefore, the push rod that arranges between muscle and muscle is also very little, be generally the push rod of Φ 1mm, but but the distance that goods eject is higher, usually reaches more than the 150mm, the total length of push rod then can surpass 500mm so, cause push rod when ejecting goods, to fracture easily, need to change push rod, affect production efficiency.
Summary of the invention
The purpose of this utility model is the shortcoming that exists in order to overcome prior art, a kind of employing Double-ejection mode is provided, shortens push rod length, effectively improve push rod intensity, make push rod frangibility not when ejecting, the little push rod secondary ejecting mechanism of the injection mold of enhancing productivity.
The technical scheme of the little push rod secondary ejecting mechanism of the utility model injection mold is: comprise upper mould plate and lower bolster, cope match-plate pattern connects solid plate through backing plate, cover half is pulled middle installation fixed die insert, the mould pin is installed on the lower bolster, upper plate and lower roof plate are set between the mould pin, on the mould pin moving platen is installed, moving die insert is installed in the moving platen, the goods that moulding is arranged between moving die insert and the fixed die insert, it is characterized in that mounting limit piece in the described lower bolster, be shaped with stopper slot in the limited block, distance screws be installed in the stopper slot, described on, jacking block is installed in the lower roof plate, distance screws is passed limited block and is connected jacking block, be equipped with ejector spring between jacking block and the limited block, connect push rod on the jacking block, the bottom surface of described moving platen is shaped with groove, arrange in the groove, lower ejector retainner plate, on push rod connects, lower ejector retainner plate, on, connecting ejector pin on the lower ejector retainner plate, thimble pass moving platen and moving die insert contacts with goods.
The little push rod secondary ejecting mechanism of injection mold of the present utility model, during die sinking, under the effect of injection machine ejecting mechanism, promote upper and lower top board start and eject, simultaneously, jacking block ejects with push rod start under the effect of ejector spring, and behind the ejection stroke that reaches the reservation of stopper slot and distance screws, jacking block stops to eject, and upper and lower top board continues to eject, drive on the push rod and push up, the thimble that push rod drives on the upper and lower ejector retainner plate ejects goods, reaches demoulding purpose.This programme adopts upper and lower ejector retainner plate and the thimble that Double-ejection is installed at push rod, by the ejection stroke that stopper slot and distance screws are reserved, realizes Double-ejection, shortened the length of push rod, improved push rod intensity, push rod can not fractureed, the smooth ejection device of goods is enhanced productivity.
The little push rod secondary ejecting mechanism of injection mold of the present utility model, described groove oral area is equipped with the guiding fixed head, push rod passes the guiding fixed head, on the guiding fixed head guide post is installed, guide post passes upper and lower ejector retainner plate, be equipped with guide pin bushing between upper and lower ejector retainner plate and the guide post, guide post and guide pin bushing have been arranged, make that upper and lower ejector retainner plate is upper and lower to eject accurate location.
