Description
Technical field
The utility model relates to the injection mold secondary ejecting mechanism, and after particularly relating to a kind of front top plate and stopping to eject, back top board continues to eject, and is applicable to the middle-size and small-size precise injection molding mould of all kinds of high requests, belongs to the mould of plastics field.
Background technology
Secondary ejecting mechanism is an extrusion technique commonly used in the mould; in the secondary extrusion technique of routine; normally behind two groups of top board one top lifting one segment distances in front and back; back top board is spacing to stop; make front top plate continue to eject by various structures; be equivalent to divide two groups by different ejecting apart from ejecting ejecting element, purposes such as power are held in the demoulding or subduction tightly by force outward thereby reach die cavity.But the first order ejects the short and second level of distance and ejects distance when very long during some product die sinkings design, ejects the intensity life-span of element for keeping the small size moulding, and front top plate stops earlier in the time of need ejecting, and back top board pushes up the secondary ejecting structure of a segment distance again.And in the traditional handicraft of the secondary ejecting mechanism of this type, for example all there is processing difficulties in ball axle sleeve type etc., shortcoming such as reliability is low.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, provides a kind of employing to separate voussoir and sliding block cooperates, make front top plate stop to eject after, the injection mold secondary ejecting mechanism that back top board continues to eject.
The technical scheme of the utility model injection mold secondary ejecting mechanism is: comprise top board and base plate, top board connects die cavity, sprue bush and centring ring are installed in the middle of the top board, square iron is installed on the base plate, core is installed on the square iron, constitute die cavity between die cavity and the core, goods are arranged in the die cavity, goods have the circle muscle in core one side, and there is the protruding glue of side position circle muscle inboard, and the square iron inboard is provided with front top plate and back top board, connect fuse and core bar on the front top plate, connect push rod on the back top board, it is characterized in that described front top plate comprises front top plate panel and front top plate base plate, the square iron inboard is shaped on hanging platform, the front top plate base plate is located on the hanging platform, loam cake and lower cover are installed between front top plate panel and front top plate base plate, between loam cake and the lower cover sliding block are installed, the end face of sliding block is shaped on the separation dovetail groove, the bottom surface of sliding block is shaped on the dovetail groove that resets, be equipped with spring between one side of sliding block and loam cake and the lower cover, below core, install separate voussoir, separate voussoir and separate dovetail groove and match; Described back top board comprises back top board panel and back top board base plate, on the back top board panel jacking block is installed, jacking block passes the front top plate base plate and contacts with the sliding block bottom surface, the voussoir that resets is installed on the base plate, and the voussoir that resets passes back top board panel and back top board base plate and the bottom surface of the sliding block dovetail groove that resets and matches.
Injection mold secondary ejecting mechanism of the present utility model, after the die sinking, the injection machine ejection system promotes back top board panel and back top board base plate moves upward, jacking block on the back top board panel withstands on the bottom surface of sliding block, promoting front top plate panel and front top plate base plate moves upward together, when the separation dovetail groove of slide damper is run into the separation voussoir that is installed in below the core, the spring compression, slide damper is toward spring one side shifting, slide damper bottom surface and jacking block are disengaged, separate voussoir and play position-limiting action this moment, withstand the front top plate panel and the front top plate base plate halts, back top board panel and back top board base plate continue to move upward under the promotion of injection machine ejection system and finish secondary and eject.When resetting (matched moulds), front top plate panel and front top plate base plate move downward with back top board panel and back top board base plate, make and separate the separation dovetail groove that voussoir leaves the sliding block end face, sliding block moves under the effect of spring thrust outward, the bottom surface of sliding block has been blocked jacking block again, the voussoir that resets at last inserts the dovetail groove that resets below the sliding block, and mould assembling action is finished.The secondary ejecting mechanism of this programme, adopt and separate voussoir and sliding block fit system, after making front top plate (front top plate panel and front top plate base plate) stop to eject, back top board (back top board panel and back top board base plate) continues to eject, it is good to eject component strength, long service life, handling ease is applicable to the middle-size and small-size precise injection molding mould of all kinds of high requests.
