Abstract
The invention relates to a large angle ejection mechanism for injection molding. The large angle ejection mechanism comprises an angle ejection body, wherein an ejector rod is arranged at the bottom end of the angle ejection body; a sliding chute is formed in the bottom end of the angle ejection body; a sliding block is arranged at the top end of the ejector rod, and is arranged in the sliding chute of the angle ejection body in a sliding mode; the bottom end of the ejector rod is fixedly connected with a mounting seat; the extension direction of the sliding chute is the horizontal direction, and the ejector rod is perpendicular to the extension direction of the sliding chute. A large angle ejection is divided into two parts, so that a large amount of manufacturing materials can be saved and thus the manufacturing cost is reduced. The large angle ejection mechanism is good in force transmission effect and smooth and steady in movement.
Description
Technical field
The present invention relates to injection molding art ejecting mechanism, particularly the large pitched roof mechanism of a kind of injection moulding.
Background technology
Die pitched roof is used for the mechanism of formed product inner barb in Design of Dies.When manufacturing some and there is the large-scale injection molding of inner barb, need the large pitched roof mechanism adopting some volume ratios larger.General oblique top is all made in one piece, and therefore when manufacturing large pitched roof mechanism, materials cost is very large.And also to process the very long inclined hole of stroke to adapt to large oblique top when making supporting template.The manufacturing cost that above factor all result in large pitched roof mechanism is very high.
Summary of the invention
The object of this invention is to provide a kind of materials being fabricated few, the large pitched roof mechanism of injection moulding of stable movement.
The technical scheme realizing the object of the invention is: the present invention has oblique top body; The bottom of described oblique top body is provided with push rod; The bottom of described oblique top body is provided with chute; The top of described push rod is provided with slide block, and skid is arranged in the chute of oblique top body; The bottom of described push rod is fixedly connected with mount pad; Described chute along to stretch direction be horizontal direction, it is vertical that direction is stretched on push rod and the edge of chute.
The plane that above-mentioned slide block coordinates with chute is equipped with ball set; Described ball set is rolled and is embedded on slide block, the exposed face of ball set and the contact internal walls of chute.
As distortion, the plane that above-mentioned slide block coordinates with chute is equipped with needle roller group; Described needle roller group is rolled and is embedded on slide block; On described slide block with the axis of each needle roller of the needle roller group in the plane of chute bottom vertical all with the axis being parallel of push rod; The axis of each needle roller of the needle roller group in plane parallel with bottom chute on described slide block is all parallel with bottom chute with the axes normal of push rod; The described exposed face of needle roller group and the contact internal walls of chute.
Supportingly on above-mentioned oblique top body be provided with oblique top guide plate; The surface of described oblique top guide plate and oblique top body contacts offers oil-way.
Above-mentioned oblique top body is provided with netted oil-way.
The present invention has positive effect: large pitched roof mechanism is divided into oblique top body and push rod two parts by (1) the present invention, by push rod Substitute For Partial oblique top body, can save a large amount of materials, reduces manufacturing cost; (2) push rod of the present invention moves vertically, only need make upright opening, substantially increase degree easy to make when therefore offering pilot hole in template; (3) the present invention arranges ball set or needle roller group and can ensure that push rod is more stable when promoting large oblique top on the slide block of push rod; (4) the present invention arranges oil-way and all can reduce wear on oblique top guide plate and oblique top body, improves service life.
