Abstract
A demolding mechanism for an internal circle inverted buckle of a sealed pipeline comprises an upper compound plate and a lower compound plate. The upper compound plate is connected with a fixed mold plate, and the fixed mold plate is connected with a fixed mold insert block. A spacer block and a moving mold plate are arranged on the lower compound plate, and the moving mold plate is connected with a moving mold insert block. A mold cavity is formed between the fixed mold insert block and the moving mold insert block, a sealed pipeline is arranged inside the mold cavity, and an inverted buckle demolding mechanism is arranged on an internal circle at the port of sealed pipeline. The demolding mechanism is characterized in that the internal circle inverted buckle demolding mechanism comprises an inclined jacking block and an inclined guide post symmetrically arranged on the fixed mold plate, the inclined guide post passes through the inclined jacking block, a nitrogen gas cylinder is arranged inside the inclined jacking block and drives the inclined jacking block to move along the inclined guide post, symmetric internal drawing slippers are arranged on the moving mold insert block and are driven by an internal drawing cylinder to draw a mold core, a center locking piece is arranged on the fixed mold plate, and during mold matching, the inclined jacking block and the internal drawing slippers contact with the center locking piece. The demolding mechanism realizes contraction demolding of a large-sized internal circle at the port of the pipeline, ensures the strength, prolongs the service life of the mold, and reduces the manufacturing cost of the mold.
Description
Technical field
The utility model relates to tube sealing road mould, particularly relates to the mould emptier of annulus back-off in a kind of large-scale tube sealing road, belongs to the mould of plastics field.
Background technology
Annulus back-off in the general pipeline uses the harmomegathus core, and the demoulding is easy, but the contract by distance of this mechanism is limited, is applicable to the interior annulus back-off of small distance (being no more than 10mm).If the monolateral 10mm that surpasses of the interior annulus back-off of pipeline, the interior annulus back-off in particularly a kind of tube sealing road, it is monolateral even reach 28mm, uses existing harmomegathus core can't realize so large-sized contraction at all, even realize that its mechanism's intensity also is difficult to guarantee the normal service life of mould.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art; a kind of demoulding that helps is provided, guarantees mould strength again, increase service life; and the reduction die manufacturing cost is specially adapted to large scale and shrinks annulus back-off mould emptier in the tube sealing road of the demoulding.
The technical scheme of annulus back-off mould emptier is in the utility model tube sealing road: comprise compound plate and following compound plate; last compound plate connects solid plate; solid plate connects fixed die insert; mould pin and moving platen are installed on the following compound plate; moving platen connects moving die insert; constitute die cavity between fixed die insert and the moving die insert; the tube sealing road is arranged in the die cavity; the interior annulus of tube sealing road oral area has the back-off mould emptier; it is characterized in that described interior annulus back-off mould emptier comprises that symmetry is installed in slanted kicking block and the Angle Pin on the solid plate; Angle Pin passes slanted kicking block, and the nitrogen cylinder is installed in the slanted kicking block, and the nitrogen cylinder drives slanted kicking block and slides along Angle Pin; on moving die insert, install symmetry in take out slide block; in take out slide block and drive by interior oil pumping cylinder and loose core, mounting center lock dog on the solid plate, during matched moulds slanted kicking block and in take out slide block and contact with the center lock dog.
Annulus back-off mould emptier in the tube sealing of the present utility model road; during the demoulding; injection moulding machine mould open at first; drive moving platen by power; moving die insert and fixed die insert are to assigned address; solid plate is motionless; the center lock dog is fixed on the solid plate also motionless; make slanted kicking block with in take out slide block and separate with the center lock dog; then; the nitrogen cylinder drives slanted kicking block and slides along Angle Pin, with the interior annulus of slanted kicking block band from tube sealing road oral area, then injection machine once more die sinking to range; driving moving die insert slides once more; make be installed on the moving die insert in take out slide block and slanted kicking block staggers up and down, then in the oil pumping cylinder take out slide block in driving and loose core and inwardly contract, the interior annulus of taking out slide block and tube sealing road oral area in making disengages; by ejecting mechanism product is ejected at last, the demoulding is finished.This programme has realized that the annulus large scale is shunk the demoulding in the pipeline oral area, when guaranteeing mould strength, increasing service life, has reduced die manufacturing cost again.
Annulus back-off mould emptier in the tube sealing of the present utility model road is taken out in it is described and is equipped with guide pad on the slide block, and gib block is installed in the guide pad, in take out slide block and loose core along gib block, had gib block to cooperate with guide pad, in slide smoothly when taking out slide block and loosing core.On its described center lock dog limited block is installed, limited block contacts with retaining groove on the slanted kicking block, prevents that slanted kicking block from deviating from mould.Mounting plate in its described solid plate, Angle Pin is installed on the fixed head, and is easy to connect, and it is firm to install.Its described center lock dog outer wall is installed wearing plate, and wearing plate has been arranged, slanted kicking block and in wear-resistant when taking out slide block and contact with the center lock dog, guarantee service life, can regulate simultaneously slanted kicking block with in take out slide block and center lock dog the gap, replacing is conveniently.
