Abstract
The utility model relates to an angle lifter mold-stripping mechanism without an ejector pin plate. An angle lifter with a limiting pin is arranged in a movable mold cavity which is arranged in a movable mold plate, an elastic pin is arranged under the angle lifter, and a spring is arranged under the elastic pin and pressed by a spring pressure plate which is locked by a fastening screw. The angle lifter mold-stripping mechanism without the ejector pin plate is characterized in that the thickness of the angle lifter is reduced to be not more than the thickness of the movable mold cavity, the elastic pin provides push from the bottom, and the design of the ejector pin plate of the conventional angle lifter mechanism is omitted. When the mold is stripped, the pull force of the product and the push force of the elastic pin commonly act to lead the angle lifter to move forward, and a buckle of the product is gradually stripped off the angle lifter, and the angle lifter stops moving when the limiting pin of the angle lifter is collided with the movable mold cavity, and can be reset when the mold compounding is conducted again. The whole movement process of the angle lifter is limited in the hole of the movable mold cavity, thus preventing the angle lifter from being blocked.
Description
Technical field
The utility model relates to a kind of back-off mould emptier of injection mold.
Background technology
At present, known oblique top mould emptier be by Xie Ding, go up ejector retainner plate, ejector retainner plate, ejector retainner plate holding screw and mavable module core, moving platen combine down.When ejector retainner plate travelled forward, tiltedly the top can advance along the inclined hole in mavable module core and the moving platen, and made the product back-off break away from tiltedly top.But such structural requirement tiltedly top is long, when tiltedly serving as a fill-in order more for a long time, occurs oblique top stuck phenomenon easily.
Summary of the invention
In order to overcome existing oblique top mould emptier stuck deficiency easily, the utility model provides a kind of oblique top mould emptier that does not have ejector retainner plate, and this mechanism has avoided tiltedly serving as a fill-in order easy stuck deficiency when too much.
The utility model solves the technical scheme that its technical problem adopted: will tiltedly push up to be contracted to and be no more than mavable module core thickness, by playing pin thrust will be provided below, and the ejector retainner plate design of the existing tiltedly top of cancellation mechanism.The oblique top that spacer pin is housed is contained in the mavable module core, and mavable module core is contained in the moving platen, tiltedly below the top bullet pin is arranged, and playing has spring below the pin, and spring is being pressed by spring bearer plate, and spring bearer plate is locked by holding screw.The pulling force of product travels forward oblique top with the thrust acting in conjunction that plays pin when the mould die sinking; And make the back-off of product break away from oblique top gradually; When the spacer pin on oblique top is run into mavable module core; Tiltedly the top is with regard to stop motion, and oblique top will be reset when matched moulds once more, and tiltedly the whole motion process on top all is limited in the mavable module core hole.
The beneficial effect of the utility model is in the smooth demoulding of the back-off of product, to significantly reduce the stuck possibility in oblique top.
Description of drawings
Fig. 1 is the structure chart of the oblique top mould emptier of no ejector retainner plate
1. oblique tops among the figure, 2. mavable module core, 3. oblique top spacer pin 4. plays pin, 5. moving platen, 6. spring, 7. spring bearer plate, 8. pressing plate holding screw.
The specific embodiment
At moving platen 5 bottom slots, packing into plays pin 4 and spring 6, with pressing plate holding screw 8 locking spring pressing plates 7, oblique top spacer pin 3 is packed into tiltedly push up 1 again, will tiltedly push up 1 together with mavable module core 2 moving platen 5 of packing into.The pulling force of product travels forward oblique top 1 with the thrust acting in conjunction that plays pin 4 when the mould die sinking; And the back-off that makes product breaks away from oblique top 1 gradually, when the spacer pin 3 on oblique top 1 is run into mavable module core 2, tiltedly pushes up 1 with regard to stop motion; When matched moulds once more, tiltedly pushing up 1 will be reset.Like this, tiltedly pushing up 1 whole movement travel all is limited in being not more than in the scope of mavable module core 2 thickness.
Claims (1)
1. oblique top mould emptier that does not have ejector retainner plate is characterized in that: will tiltedly push up to be contracted to and be no more than mavable module core thickness, and by playing pin thrust will be provided, the oblique top that spacer pin is housed is contained in the mavable module core; Mavable module core is contained in the moving platen, tiltedly below the top bullet pin is arranged, and playing has spring below the pin; Spring is being pressed by spring bearer plate, and spring bearer plate is locked by holding screw, and the pulling force of product travels forward oblique top with the thrust acting in conjunction that plays pin when the mould die sinking; And make the back-off of product break away from oblique top gradually, when the spacer pin on oblique top was run into mavable module core, tiltedly the top was with regard to stop motion; When matched moulds once more, tiltedly the top will reset, and tiltedly the whole motion process on top all is limited in the mavable module core hole.
