Abstract
The utility model relates to three board molds of preceding ejection to realize the preceding mould installation of ejector beam by the way that liftout plate is arranged on middle mould；Then, by the way that interlock is arranged, interlock is connected by the stayed mast of rear mold, ejects moulding before realizing；Frizzen is mobile relative to rear mold with preceding mould, after the completion of ejection, to realize triggering unlock, solves the problems, such as that existing mold can not forward direction (i.e. by preceding mould towards rear mold direction) ejection.
Description
Technical field
The utility model belongs to injection mold technology, is specifically related to a kind of sinciput that can be carried out preceding mould ejection demoulding
Three board mold out.
Background technique
In existing injection mold, usually by fixing several ejector beams on liftout plate/die pad, extend to liftout is dry
In die cavity, liftout plate is pushed after die sinking, realizes the ejection device of moulding finished product.
In the prior art, ejection direction is from the front to the back: since preceding mould (also referred to as cover half) is set to injection molding machine injecting glue
In mechanism, driving part can not be increased, liftout plate is fixed on rear mold (also referred to as dynamic model), by the de- material oil on injection molding machine
Cylinder drives liftout plate to move back and forth and realizes de- material.
However, in product actual production process, in the product that especially surface quality requirements are high and surface area is big, one
As appearance should not leave gum-injecting port, liftout trace etc., and injecting glue runner extends the too long formed product that is not able to satisfy of bending and needs
It asks, therefore is badly in need of the injection mold before one kind to ejection.
Summary of the invention
The utility model ejects three board molds before being intended to provide one kind, with solve existing mold can not forward direction ejection ask
Topic.
Concrete scheme is as follows: three board molds, including preceding mould, middle mould and rear mold are ejected before a kind of；Further include liftout plate with
And drawing-plate mechanism；
The liftout plate can be actively set in this on mould, and the liftout protruded out towards rear mold direction is additionally provided on the liftout plate
Bar；
The drawing-plate mechanism includes an interlock, a stayed mast and a frizzen；The interlock is set to the liftout plate
On, the stayed mast and frizzen are respectively arranged on the rear mold and preceding mould；
The stayed mast and frizzen are each passed through the interlock, be respectively used to the interlock hook it is sealed and
Trigger interlock unlock.
The further technical solution of the utility model are as follows: the drawing-plate mechanism has two groups, is respectively arranged on before and after the liftout plate
The position of opposite sides on direction；And two the drawing-plate mechanism be respectively arranged on the both ends on the liftout plate left and right directions.
The further technical solution of the utility model are as follows: the interlock includes a mounting blocks, a sliding shoe and a bullet
Property part；
The mounting blocks are fixed on the side of the liftout plate, and the mounting blocks are equipped with one towards the extension of stayed mast direction
Sliding slot, the sliding shoe can be actively set in the sliding slot；
The elastic component, which is set to, applies one towards the position of stayed mast direction migration power to the sliding shoe.
The further technical solution of the utility model are as follows: the top of the stayed mast is in L font, with towards the sliding shoe end
The region of top position protrudes out to form a clamping part.
The further technical solution of the utility model are as follows: the region of deviated from stayed mast is additionally provided with a triggering on the sliding shoe
Hole, which passes through the triggering hole, and the free end of the frizzen is additionally provided with a solution closing piece protruded out away from stayed mast direction.
The liftout plate is set to the side of deviated from rear mold on mould in this, and mould can be movably arranged in the rear mold in this.
The utility model has the advantages that three board mold of preceding ejection of the utility model realizes liftout by the way that liftout plate is arranged on middle mould
The preceding mould of bar is installed；Then, by the way that interlock is arranged, interlock is connected by the stayed mast of rear mold, ejection injection molding before realizing
Part；Frizzen is mobile relative to rear mold with preceding mould, after the completion of ejection, to realize triggering unlock, solve existing mold can not before
To the problem of (i.e. by preceding mould towards rear mold direction) ejection.
Detailed description of the invention
Fig. 1 ejects three board mold front views before showing the utility model；
Fig. 2 shows the structural schematic diagrams of Fig. 1；
Fig. 3 shows Fig. 2 and removes the structural scheme of mechanism after mounting blocks.
Specific embodiment
To further illustrate each embodiment, the utility model is provided with attached drawing.These attached drawings are in the utility model discloses
A part of appearance mainly to illustrate embodiment, and can cooperate the associated description of specification former come the running for explaining embodiment
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and sheet are practical new
