Description
Technical field
The present invention relates to a kind of secondary ejecting mechanism of modified back-off bottle cap injection mold, belong to the plastics machinery technical field.
Background technology
As shown in Figure 3, have quite general that the vinyl cover 7 of back-off 71 uses in daily life, when making this vinyl cover 7, the demoulding is difficulty relatively at present, after ejecting mechanism ejects die cavity with vinyl cover 7, because the existence of back-off 71, vinyl cover 7 still is buckled on the ejector sleeve of ejecting mechanism, needs manual taking off by force to get lid, operation is extremely inconvenient, improved production cost, reduced production efficiency, and easily production accident has taken place.Once designed a kind of secondary ejecting mechanism (as shown in Figure 1) at this problem inventor, comprise cover half 3 and dynamic model 6, form die cavity between cover half 3 and the dynamic model 6, described cover half 3 is installed on the solid plate by the mould pin, ejector sleeve ejector retainner plate 5 and ejector sleeve fuse ejector retainner plate 4 are arranged between cover half 3 and the solid plate, ejector sleeve 8 is installed on the ejector sleeve ejector retainner plate 5, ejector sleeve fuse 9 is installed on the ejector sleeve fuse ejector retainner plate 4, wherein ejector sleeve fuse 9 is positioned at ejector sleeve 8, match with die cavity in the position of described ejector sleeve 8, described ejector sleeve ejector retainner plate 5 and ejector sleeve fuse ejector retainner plate 4 drive by oil cylinder, when oil cylinder drives ejector sleeve ejector retainner plate 5, ejector sleeve 8 ejects the oil cylinder that drives ejector sleeve ejector retainner plate 5 behind the die cavity with the vinyl cover in the die cavity 7 and quits work, this moment, vinyl cover 7 still was buckled on the ejector sleeve 8 because of the existence of back-off, the oil cylinder that drives ejector sleeve fuse ejector retainner plate 4 is then started working, ejector sleeve fuse the last 9 top vinyl cover 7 breaks away from the back-off of vinyl cover 7 and ejector sleeve 8, has realized the demoulding.Though having realized need not manually-operated, this mechanism can carry out the demoulding to the vinyl cover that has back-off, but because two ejector retainner plates drive by oil cylinder, the structure more complicated, and must just can carry out the demoulding after the first die sinking, production cycle is long, efficient is low, the more important thing is to be that two oil cylinders are equipped with control device, make the orderly work of two oil cylinders, production cost significantly improves.
Summary of the invention
The purpose of this invention is to provide a kind of two ejector retainner plates of controlling mechanically moves in order, need not to join power and control device in addition for ejector retainner plate, thereby simplify mould structure, reduce production costs, and the demoulding and die sinking carry out synchronously, shortened the production cycle, improved the secondary ejecting mechanism of the modified back-off bottle cap injection mold of production efficiency.
The technical solution adopted in the present invention is to achieve the above object of the invention:
The secondary ejecting mechanism of modified back-off bottle cap injection mold, comprise fixed half and moving half, form die cavity between the fixed half and moving half, described cover half is installed on the solid plate by the mould pin, ejector sleeve ejector retainner plate and ejector sleeve fuse ejector retainner plate are arranged between cover half and the solid plate, on the ejector sleeve ejector retainner plate ejector sleeve is installed, the ejector sleeve fuse is installed on the ejector sleeve fuse ejector retainner plate, wherein the ejector sleeve fuse is positioned at ejector sleeve, match with die cavity in the position of described ejector sleeve, it is characterized in that described ejector sleeve ejector retainner plate and ejector sleeve fuse ejector retainner plate are driven by drag hook mechanism, described drag hook mechanism comprises first slide block that is installed on the ejector sleeve ejector retainner plate, be installed in second slide block on the ejector sleeve fuse ejector retainner plate, be fixed on the drag hook that a leading truck on the solid plate and an end are positioned at leading truck, the other end of drag hook is fixed on the dynamic model, be shaped on first guide runner and second guide runner on the described leading truck, the lower wall of two guide runners is the inclined-plane, between described first slide block and the ejector sleeve ejector retainner plate, be provided with spring between second slide block and the ejector sleeve fuse ejector retainner plate, be shaped on first projection and second projection on the described drag hook, first projection drives first slide block and matches with first guide runner, second projection drives second slide block and matches with second guide runner, and the thickness of described second projection is greater than the thickness of first projection.
The characteristics of the technical program are to adopt two motions that ejector retainner plate is orderly of mechanical system control secondary ejecting mechanism, and then the vinyl cover that has back-off is carried out the demoulding.Detailed process is as follows: during the injection mold die sinking, dynamic model drives drag hook and moves down, first projection of drag hook drives first slide block and the ejector sleeve ejector retainner plate moves down, second projection drives second slide block and ejector sleeve fuse ejector retainner plate moves down, first slide block and second slide block extrusion spring under the effect on guide runner inclined-plane moves to the ejector retainner plate direction in the folding process, separate with first projection until first slide block, the ejector sleeve ejector retainner plate stops to move down, this moment, the vinyl cover in the die cavity partly broke away from the cover half of die cavity under the effect of ejector sleeve ejector sleeve fuse, but because the existence of back-off still is buckled on the ejector sleeve, this has just finished for the first time and has ejected; Dynamic model continuation drive drag hook moves down then, the thickness of cause second projection is greater than the thickness of first projection, when first slide block has just separated with first projection, second projection still contacts and drive second slide block with second slide block and ejector sleeve fuse ejector retainner plate continues to move down, and because ejector sleeve blocks the back-off transfixion of vinyl cover, therefore strong top vinyl cover breaks away from the back-off of vinyl cover and ejector sleeve in the folding process of ejector sleeve fuse, and this has just realized that secondary ejects.The technical program need not manually-operated pickup so the reduction of production accident incidence after adopting secondary ejecting mechanism, and improved production efficiency, reduced production cost, most importantly two of secondary ejecting mechanism ejector retainner plates drive by drag hook mechanism, need not to join power and control device in addition for ejector retainner plate, thereby simplify mould structure, reduce production costs, and the demoulding and die sinking carry out synchronously, shortened the production cycle, improved production efficiency.
All be shaped on the spring hole on described ejector sleeve ejector retainner plate and the ejector sleeve fuse ejector retainner plate, first slide block and second slide block are movably arranged in the spring hole, and described spring is arranged in the spring hole and two ends contact mutually with ejector retainner plate and slide block respectively.Slide block slip horizontal slip in the spring hole, spring is positioned at the compression of spring hole, moves more steady.
