Description
Technical field
The present invention relates to injection molds, more particularly to the side action sliders strength positioning mechanism of injection mold.
Background technique
In injection mold, if the side wall of plastic part is formed with the structures such as buckle, back-off, side perforation, the ejector in mold
Structure can not be directly by plastic part ejection device, it is therefore desirable to side action sliders and drive be arranged in the sidewall locations of the plastic part
The inclined guide pillar structure structure made is twitched in its side, in mold die sinking, first passes through inclined guide pillar and drives the outside side core-pulling of side action sliders
After the structures such as abjection buckle, back-off, perforation, then by ejecting mechanism by plastic part ejection device, and side is driven to take out in inclined guide pillar
After core sliding block is laterally extracted out, due to the oblique guide hole of inclined guide pillar abjection side action sliders, it is therefore desirable to which positioning mechanism is sliding to side core-pulling
Block is positioned, it is made to be fixed on designated position, and inclined guide pillar can reinsert the oblique of side action sliders when being conducive to mold clamping
In guide hole, side action sliders is driven to reset.The positioning mechanism of existing injection mold side action sliders is usually to be provided on type core
Spring is arranged in mounting groove, convex nozzle is arranged on spring, and be formed with positioning groove in the bottom of side action sliders for mounting groove,
In non-core pulling state, the bottom plane of side action sliders pushes down convex nozzle, make its contracting in mounting groove, when side action sliders to
When outer side core-pulling is moved to designated position, the positioning groove of side action sliders bottom is corresponding with convex nozzle, in spring-return
It pushing convex nozzle ejecting card in positioning groove under the action of power, plays positioning action, the detenting force of the structure is weaker,
The side action sliders transversely and horizontally acted are usually only useful in, and since part mould uses horizontal type structure, side action sliders need
Upward core pulling or downward core pulling are wanted, heavier-weight, convex nozzle structure can not play the positioning support of strength to it, thus shadow
Ring locating effect.
Summary of the invention
The purpose of the invention is to overcome prior art there are the shortcomings that, provide a kind of pair of side action sliders play strength
Positioning support, when making mold clamping, inclined guide pillar can be properly inserted in the oblique guide hole of side action sliders, guarantee that mould open/close mould is dynamic
Make the side action sliders strength positioning mechanism of accurately injection mold.
The technical solution of the side action sliders strength positioning mechanism of injection mold of the present invention is: including preceding compound plate and multiple afterwards
Plate, setting type chamber on preceding compound plate are arranged inclined guide pillar in type chamber, perforation are provided in rear compound plate, are arranged support block on rear compound plate, support block it
Between rear compound plate on sinciput needle plate, back center plate and thimble are set, the mandril of injector passes through perforation and is in contact with back center plate,
The setting type core on support block is arranged side action sliders above or below type core, oblique guide hole, oblique guide hole is provided in side action sliders
It is matched with inclined guide pillar, mounting groove is provided on the type core, locating piece is set in mounting groove, is provided with fixation hole in locating piece,
Locating piece passes through fixation hole through fastener and mutually fixes with type core, and two panels symmetrical elastic clip in left and right is formed on front side of locating piece
And locating slot, it is located at mounting groove side setting positioning pin in side action sliders, positioning pin is matched with elastic clip and locating slot.
The invention discloses a kind of side action sliders strength positioning mechanisms of injection mold, are primarily adapted for use in horizontal injection mould
Strength positioning is carried out in tool when side action sliders core pulling action upward or downward, when injection mold die sinking, by rear compound plate band
Dynamic model foot, sinciput needle plate, back center plate, thimble, type core, side action sliders, locating piece and the plastic part of injection molding together to
Rear side is mobile, and preceding compound plate, type chamber and inclined guide pillar remain stationary, and side action sliders are cooperated by oblique guide hole and inclined guide pillar, makes side
Core-pulling slide block extracts the side opening structure of plastic part out along the inclined direction of inclined guide pillar gradually downward, while side action sliders drive and determine
Position pin moves down, and is caught in positioning pin gradually downward in the locating slot of locating piece, is taken out by locating piece to positioning pin and entire side
Core sliding block plays positioning and supporting role, fixed reliable since locating piece is fixed on type core by fastener, and locating piece is whole
Body structural strength is high, supports reliably to positioning pin, and the groove profile of locating slot is just corresponding with the surface circular arc of positioning pin, and ties
The two sides that elastic clip clamps positioning pin are closed, avoid it that beat or abjection occurs, to guarantee positioning pin and entire side core-pulling
Sliding block obtains strength and accurate positioning support.
The side action sliders strength positioning mechanism of injection mold of the present invention, between the symmetrical elastic clip of left and right two panels
Open slot is formed, the open slot includes the arc flaring of oral area, and arc flaring inside is formed with arc necking, arc flaring,
Arc necking and locating slot communicate, and the internal diameter of arc flaring is greater than the internal diameter of locating slot, and the internal diameter of arc necking is less than locating slot
Internal diameter.When side action sliders drive mobile to the side core pulling of positioning pin, the arc flaring structure of larger interior diameter, be conducive to
Positioning pin is aligned and is caught in, and can be corresponding with the lesser arc necking of internal diameter under the guiding role of arc surface, and interior
The lesser arc necking of diameter can make positioning pin after being caught in locating slot, play certain clamping, positioning action to positioning pin.It is described
Two panels symmetrical elastic clip outer wall in left and right is formed with arc groove.On the one hand curved slot arrangement reduces the thickness of elastic clip, makes it
With good elasticity capacity, elastic clip structural strength on the other hand can be improved, guarantee its service life.
