Description
Technical field
The utility model relates to a kind of automobile taillight lampshade mould back-off mould emptier, belongs to the mould of plastics field.
Background technology
Adopt injection mold to produce plastic product, as automobile taillight lampshade, the back side of lampshade is shaped on the welding muscle with the tail-lamp base assembling, the prior art welding muscle and the lampshade back side are perpendicular, its advantage is to eject easily, and the ejecting mechanism of mould can directly eject lampshade, but the shortcoming of its existence is: the junction of welding muscle and lampshade can produce a heavy wall district, shunk easily in the surface of lampshade, influence good looking appearance.Therefore, shrink in order to reduce the lampshade surface, with the oblique design of welding muscle of lampshade, still, such design makes the inboard of welding muscle and lampshade junction form a back-off, directly ejection device.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art; provide and take out oblique sliding mode in a kind of employing; make the welding muscle of oblique design and the smooth demoulding of back-off that the lampshade junction forms; simple in structure; action is stable, guarantees the automobile taillight lampshade mould back-off mould emptier of lampshade good looking appearance.
The technical scheme of the utility model automobile taillight lampshade mould back-off mould emptier is: comprise compound plate and following compound plate; last compound plate connects the cover half frame through cushion block; fixed die insert is installed in the cover half frame; mould pin and top board are installed on the following compound plate; connect push rod on the top board; the dynamic model frame is installed on the mould pin; moving die insert is installed in the dynamic model frame; the automobile taillight lampshade that moulding is arranged between moving die insert and the fixed die insert; the back side of lampshade is shaped on the welding muscle, and the junction of welding muscle and lampshade constitutes back-off, it is characterized in that dynamic model frame bottom installation inner bottom plating and locating piece; slide on the base plate inner slide is set; one side of inner slide is shaped on oblique chute, tiltedly takes out piece in oblique the setting on the chute, in take out the side that piece tilts and contact with locating piece; in take out piece the top match with back-off; be equipped with oil cylinder in the dynamic model frame, the piston rod of oil cylinder passes the dynamic model frame and is connected with inner slide with locating piece, drives inner slide and slides; the opposite side of inner slide has lock dog, and lock dog passes the dynamic model frame and is connected with the cover half frame.
Automobile taillight lampshade mould back-off mould emptier of the present utility model; during the demoulding; at first drive dynamic model frame and the die sinking of cover half frame by injection machine power; in the die sinking process; the dynamic model frame moved down before this; driving inner slide and lock dog disengages; oil cylinder work again; promote inner slide to front slide; inner slide is to front slide the time, and the oblique chute of inner slide one side skids off from the interior piece bottom of taking out from high to low, make inclination in take out piece and recover horizontal level to lower slider along oblique chute; in take out piece top and back-off disengage back-off demoulding success.This programme is taken out oblique sliding mode in adopting, and makes the welding muscle of oblique design and the smooth demoulding of back-off that the lampshade junction forms, and the lampshade surface is shrink-proof, good looking appearance, and mould emptier is simple in structure, and action is stable, long service life.
