Description

A die sinking both direction core-pulling mechanism
Technical field
The utility model relates to an a kind of die sinking both direction core-pulling mechanism.
Technical background
In actual production, often run into some and have simultaneously vertically to plastic feature holes and the product that is tilted to the plastic feature holes, as Figure 1-3.When the particularity of this product is the active and inactive mold demoulding and the side core-pulling demoulding be interference state, as shown in Figure 4, cause when producing this product, need realize the active and inactive mold demoulding and the side core-pulling demoulding in two steps.
The mould structure of existing this kind of production product is: comprise the cover half fixed head, have cover half benevolence solid plate, have the moving platen of mavable module core and be slidably mounted on left slider and right slide block on the moving platen, mavable module core, cover half benevolence and left and right slide block are enclosed injection molding plastic die cavity, be fixed with the latch segment of when the matched moulds state, locking slide block respectively on the solid plate, be fixed with the Angle Pin of difference guide runner motion when die sinking on the solid plate;
Be fixed with first mold insert of moulding incline direction feature holes on the left slider, be fixed with moulding on the cover half fixed head, be fixed with the ejector sleeve adaptive on the mavable module core with second mold insert vertically to second mold insert of feature holes; Second mold insert runs through solid plate, and first mold insert is provided with the passage that allows second mold insert to pass;
Be provided with the die sinking spring between cover half fixed head and the solid plate, be provided with the resin shutter between solid plate and the moving platen.
When solid plate and moving platen were in the matched moulds state, the top of ejector sleeve embedded the bottom of second mold insert, and cover half benevolence, mavable module core and left and right slide block are enclosed the plastic die cavity.After injection moulding was finished, first mold insert and the second mold insert place formed the plastic feature holes respectively.
During die sinking, moving platen begins away from solid plate, and second mold insert breaks away from ejector sleeve, finish vertically to the loosing core of plastic feature holes, and second mold insert still was positioned at left slider inside, stoped left slider towards the direction motion away from plastic this moment.After second mold insert broke away from left slider fully, left slider to the direction motion away from plastic, finished being tilted to loosing core of plastic feature holes under the effect of left Angle Pin.
This mould structure has following shortcoming: 1, second mold insert is fixed on the cover half fixed head, need pass solid plate, left slider and aim at the ejector sleeve top again, stroke when this causes length, the folding mould of second mold insert is very long, being easy to cause because the position of second mold insert and solid plate, left slider deviation occurs can't matched moulds, mould can't use, and die life is short.2, vertically when feature holes is loosed core, need to rely on second mold insert to pin the position of left slider, and the length of second mold insert is long, causes second mold insert to be easy to deform, and causes mould to use, die life is short.3, need separate through moving, cover half during the mould die sinking, solid plate separates with the cover half fixed head, complex structure, and action is complicated.
The utility model content
For overcoming the above-mentioned shortcoming of prior art, the utility model provides a kind of mould structure simple, a die sinking both direction core-pulling mechanism of long service life.
A die sinking both direction core-pulling mechanism, comprise the cover half fixed head, have cover half benevolence solid plate, have the moving platen of mavable module core and be slidably mounted on left slider and right slide block on the moving platen, be provided with the resin shutter between described solid plate and the moving platen;
Mavable module core, cover half benevolence and left and right slide block are enclosed injection molding plastic die cavity, be fixed with the latch segment of when the matched moulds state, locking slide block respectively on the solid plate, be fixed with the Angle Pin of difference guide runner motion when die sinking on the solid plate, be fixed with first mold insert of moulding incline direction feature holes on the described left slider, described mavable module core is provided with ejector sleeve;
It is characterized in that: be equipped with the slide block pin that moulding is vertically used to feature holes on the described left slider, between described slide block pin and the left slider spring is arranged, the bottom of described slide block pin is provided with and allows the ejector sleeve top to enter its interior depressed part, during the matched moulds state, described cover half benevolence compresses described slide block pin and spring is in confined state;
On the left slider, with the cross section ovalize of the adaptive pilot hole of left Angle Pin.
Further, described left slider is made up of slide section and mold insert portion, and described first mold insert and slide block pin all are arranged at mold insert portion, and described pilot hole is arranged at slide section;
Described mold insert portion is provided with the holding tank that holds described spring, and described spring housing is located on the spring guide pin, and described slide block pin and spring guide pin are all affixed with a fixed head, and described fixed head top is provided with the limiting plate of restraining spring stroke.Further, be provided with the mold insert pressing plate between described limiting plate and the fixed head, described fixed head and mold insert pressing plate are affixed, during the matched moulds state, described cover half benevolence is close to described mold insert pressing plate.
Further, described solid plate is fixedlyed connected with the cover half fixed head.
Further, described right slide block is provided with second mold insert of the side direction feature holes on moulding plastic right side.
Technical conceive of the present utility model is: during the matched moulds state, the top of ejector sleeve enters in the depressed part of slide block pin, is formed for moulding vertically to the vertical hole of feature holes mold insert.Because of the vertically existence of the hole mold insert and first mold insert, during injection moulding, the plastics liquation can not enter in the mold insert and form vertically to feature holes and be tilted to feature holes.
After injection moulding was finished, during die sinking, moving platen began away from solid plate, because the cross section ovalize of the pilot hole on the left slider, therefore left Angle Pin can't be urged to slide block at once, make slide block delay away from the action of plastic.At this moment, left slider does not outwards slide, promptly first mold insert does not break away from plastic; And since moving platen begin away from solid plate, occur between mold insert pressing plate and the cover half benevolence gap, mold insert pressing plate under the reset response of spring away from left slider, mold insert pressing plate drive slide block pin breaks away from ejector sleeve gradually.After this, left Angle Pin is run into the inside of left slider pilot hole, drives left slider and moves to the direction away from plastic, and first mold insert breaks away from plastic.Like this, finish when a die sinking is moved, successively loose core towards both direction.
Slide block pin of the present utility model is arranged within the left slider, and the stroke of slide block pin is short during the folding mould, and pin is not easy distortion, and aims at ejector sleeve easily, and accuracy is good, and die life is long; In addition, die sinking action of the present utility model only needs the active and inactive mold separation to get final product, and action is succinct, and is simple in structure.
It is simple to the utlity model has mould structure, the advantage of long service life.
