Abstract
The utility model provides a structure with an ejector sleeve in a sliding block. A product with a convex structure with an inwards-sunken hole on one side can be molded at a time, so that the dimensional accuracy and high production efficiency are ensured. The structure comprises a front mold, a rear mold, a plate A, a plate B and the sliding block, wherein a mold cavity is formed between the front and rear molds; the product is arranged in the mold cavity; the convex structure is formed on one side of the product, and the inwards-sunken hole is formed in the convex structure; the inner side of the sliding block clings to the side, with the convex structure, of the product; an inclined guide pillar is connected to the middle part of the outer side of the sliding block; a shoveling machine is arranged on the outer inclined surface of the sliding block in a pressing way. The structure is characterized in that a mounting groove is formed in a position corresponding to the plate A on the lower part of the sliding block, wherein an ejector pin plate and an ejector retainer plate are arranged in the mounting groove, and are integrated; an inserted pin seat is positioned and clamped at the middle positions of the ejector pin plate and the ejector retainer plate.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is specially the structure that a kind of slide block inside arranges ejector sleeve.
Background technology
One side of existing product is with on projective structure and projective structure during with inward recess, it generally completes the injection moulding of projective structure by sidepiece slide block, adopt again afterwards following process to form the inward recess on projective structure, owing to having adopted secondary operations, it makes the poor dimensional precision of product, and production efficiency is low.
Summary of the invention
The structure that the utility model provides a kind of slide block inside that ejector sleeve is set, it makes a side with can one-shot forming with the product of inward recess on projective structure and projective structure, guaranteed dimensional accuracy, and production efficiency is high.
A kind of slide block inside arranges the structure of ejector sleeve, its technical scheme is such: it comprises front mould, rear mold, A plate, B plate, slide block, described front mould, between rear mold, form die cavity, in described die cavity, it is product, one side of described product is with projective structure, and on projective structure with inward recess, the projective structure side of described product is close in the inner side of described slide block, the outer middle side part of described slide block is connected with Angle Pin, shovel press-fits the inclined-plane, outside in described slide block, it is characterized in that: the lower position corresponding to described A plate of described slide block has mounting groove, in described mounting groove, be furnished with ejector retainner plate, face needle plate, described ejector retainner plate, face needle plate forms integral body, described ejector retainner plate, the centre position locator card of face needle plate is equipped with plug housing, described ejector retainner plate is run through in one end of described plug housing, after slide block, be mounted on the vertical elevation of described shovel, described ejector retainner plate is close to the inwall of the described mounting groove of respective side, between the inwall of the described mounting groove of described needle plate and respective side, leave gap, spring plug is loaded on described interstitial site, the two ends of described spring are mounted on respectively described needle plate, slide block, the butt end of ejector sleeve is installed in described ejector retainner plate, in the interfix groove of face needle plate, the taper end of described ejector sleeve runs through the outer face that is mounted on described projective structure after described slide block, the tip of ejector pin is mounted in described inward recess after running through the inner core of described ejector sleeve, the afterbody of described ejector pin is positioned in the outside locating hole of described slide block.
It is further characterized in that: described slide block has spring fitting groove corresponding to a side of described needle plate, the other end of described plug housing gos deep in described spring fitting groove after running through face needle plate, gap, described spring housing is loaded on evagination in the other end of the plug housing of described needle plate, and one end of described spring is positioned at described spring fitting groove.
Adopt after structure of the present utility model, during mould die sinking, slide block is because the power of Angle Pin is outwards moved, ejector pin is owing to being in the outside locating hole being fixed on, also and then outwards motion, ejector sleeve is owing to being fixed on ejector retainner plate, in the interfix groove of face needle plate, that plate is because one end of plug housing heads on the vertical elevation of shovel, therefore do not draw back, so just allow ejector pin extract smoothly glue position out, the height rising when shovel is greater than after vertical elevation height, ejector sleeve is along slide block together outwards motion, complete the demoulding, it makes a side with projective structure, and can one-shot forming with the product of inward recess on projective structure, guaranteed dimensional accuracy, and production efficiency is high.
