Abstract
The invention discloses an inclined pin installing structure for an ejection molding mold, comprising a male-mold core, an inclined pin and a sliding block, wherein the inclined pin and the sliding block are arranged on the male-mold core; the male-mold core is provided with a cavity; one end of the inclined pin is arranged in the cavity, and the other end of the inclined pin is provided with an inclined pin seat; a positioning step is arranged between the inclined pin and the sliding block and comprises a base and two clamping parts which are arranged on the base and are used for positioning the sliding block and the inclined pin respectively; and the two sides of the two clamping parts are respectively provided with a sliding rail. The inclined pin installing structure disclosed by the invention has the advantages that a formed product is ejected by the inclined pin and the positioning step is used for positioning, so that burrs of the formed product caused by simultaneous breaking of the sliding block and the inclined pin are avoided, and the phenomena of fracture, bending and clamping and the like of the existing ejection pin are overcome; uniform ejecting force acts on the formed product, the demolding can be ensured, the fracture of the formed product is reduced, and no marks remain on the appearance of the formed product; and the structure is simple and reasonable, the stability is high, and the demolding faults such as fracture and scratch of the formed product are avoided.
Description
Technical field
What the present invention relates to is a kind of ejector member of ejection shaping mould, and what be specifically related to is a kind of ejection shaping mould taper pin mounting structure.
Background technology
The structure of injection molding mould is changeable, different gate forms, different pushing methods and different mould structures, just various types of die form can be formed, therefore for rather difficulty that mould is clearly classified, hereby in general common classification mode, simply can to distinguish according to mold structure, double-plate mould, shree plates mold mould, runnerless mould tool and back flowing mold.This mould is when injection molding product, and injection action is complete, and after being filled in the material cooled solidification of formingspace, then form the work that product eject, now the fixation side of forming machine and drawer at movable side open stroke, and mould is that boundary starts and opens with die joint.Usually be fixed on the mould of movable plate, drawer at movable side and movable plate retreat simultaneously, then the knock-pin of mat forming machine, make the ejecting mechanism start of mould, are ejected by formed products.In order to improve injection molding efficiency, improving formed products quality, easy quicker de-mold, to eject, and reach automation mechanized operation, not only formed products, the demoulding of Lian Zhu road, runner, eject and all must select the most appropriate method.
Moulding material is depended in ejecting of formed products, the shape of formed products, the structure of mould, when ejecting, preferably do not break, scratch etc., and the really demoulding and fault is few, but, what in existing mold, fault was maximum is ejecting mechanism, as knock pin fractures, bending, block, must be able to easily study for a second time courses one has flunked or change, this just affects the effect of the demoulding, the efficiency that impact is produced, and taper pin is with snap fit, be hooked in product exit axis and have overhead kick face, side has slide block, taper pin exit axis insufficient space, easy generation slide block and taper pin breaking simultaneously formed products, it is made to produce burr, the same demoulding and the quality affecting product.
Summary of the invention
For the deficiency that prior art exists, the present invention seeks to be to provide a kind of Stability Analysis of Structures, avoid the ejection shaping mould taper pin mounting structure of slide block and taper pin breaking simultaneously, the demoulding can be guaranteed, reduce formed products to break, avoid that formed products is residual in appearance ejects vestige and burr, solve existing knock pin simultaneously and fracture, bend, the problem such as to block.
To achieve these goals, the present invention realizes by the following technical solutions:
Ejection shaping mould taper pin mounting structure, it comprises male model die, arranges taper pin interior on male model die and slide block, described male model die is provided with die cavity, described taper pin one end is placed in die cavity, it is characterized in that, the described taper pin other end is provided with oblique pin base, positioning step is provided with between described taper pin and slide block, slide block and taper pin are located fixing by positioning step, described positioning step comprises a base and is arranged on two fasteners for difference positioning sliding block and taper pin on base, and the both sides of described two fasteners are provided with slide rail.
According to above-mentioned ejection shaping mould taper pin mounting structure, wherein, described two fasteners are arranged on the same end face of positioning step, reduce electric discharge processing.
According to above-mentioned ejection shaping mould taper pin mounting structure, wherein, described taper pin top shape is cambered surface, and described taper pin front end is provided with to be faced directly, and face breaking directly and easily process, matched moulds is effective.
According to above-mentioned ejection shaping mould taper pin mounting structure, wherein, described taper pin is provided with snap fit, described snap fit is provided with reinforcement.
The present invention is by adopting positioning step and oblique pin base, guarantee ejecting and exiting of taper pin, and led by oblique pin base, it is made to adopt angle pin ejecting formed products, and located by positioning step, avoid the breaking simultaneously of slide block and taper pin and produce formed products burr, which solving the generation that existing knock pin fractures, bends, to block etc. phenomenon; It has uniform ejecting force and acts on formed products, can guarantee the demoulding, reduces formed products and breaks, and makes that formed products is residual in appearance ejects vestige, and it is simple and reasonable for structure, and stability is high, avoids the demoulding faults such as formed products breaks, scratch.
