Description
Technical field
The utility model is related to injection mold technical field, more particularly to a kind of template die runner Automatic-falling of injection mold three
Structure.
Background technology
With industrialized development, plastic cement products are molded by injection mold, for example, shell of electronic product etc.
Plastic parts, using mechanization production, yield is big, and cost is low, and injection molding technology has obtained good development, particularly electronics and produced
The popularization of product is, it is necessary to carry out each shells preparation, and the then improvement for injection mold also turns into widely studied problem.
Widely used three template die in injection production, with the de- material of product is simple, injection-molding surfaces are attractive in appearance, injection pressure
Low the characteristics of.Three template die important steps are die sinkings, and conventional three template dies have three partings, for the first time runner ejection plate and caster it
Between, for the second time between runner ejection plate and upper mounted plate, for the third time between caster and male template.Specifically, when male model side
When originally by the pulling force of injection machine, due to equipped with shutter between male and female template, and do not have between runner ejection plate and caster
Any connection and resistance, at this moment runner ejection plate is separated first with caster under a stretching force, caster with male template together
Move, when moving to setpoint distance, blocked by lower link bar limited block backward, because caster continues backward with injection machine dynamic model side
Motion, such lower link bar is also driven, and it drives runner ejection plate to move a setpoint distance again, so as to which runner is laid, this
After setpoint distance has been moved, lower link bar and caster all stop motions.Last injection machine dynamic model side continues to move backward, and pulling force is not
Disconnected increase, more than shutter coupling mechanism force, caster is separated with male template, is separated into slack during setpoint distance；In pusher pin
Promotion under, liftout plate drive ejecting mechanism start ejection action, finished product is ejected, fallen on automatically in product frame.
Because runner is the waste material that produces in injection, final to need to be separated with product, runner is flowing in existing structure
Road push pedal effect is lower to be departed from after drawing material pin, and runner continues to stay on stripper plate, is not separated with product, it is impossible to individually fall automatically
Fall, it is necessary to be taken out by manually or mechanically hand, the extension production time, reduction operating efficiency；Again because of runner ejection plate and preceding mould A plates point
Layer distribution, adds flow channel length, and the increase of runner amount of waste wastes raw material, mass production cost is high.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of injection mould for shortening runner, improving production efficiency
Have three template die runner Automatic-falling structures.
To solve the above problems, the utility model is adopted the following technical scheme that：
A kind of template die runner Automatic-falling structure of injection mold three, including panel, flange, sprue bushing, front template, lead and
Runner shape chamber, the panel is connected with flange, and the sprue bushing is connected in panel with flange；The lead is located at panel
On, the front template runs through on lead, and the runner shape chamber connects sprue bushing on front template；Set on the front template
Have to be provided with to run through on corresponding runner ejection plate, the runner ejection plate in U-type groove, the U-type groove and be provided with spacing guide screw and face
Plate is connected.
The runner ejection plate is U-shaped plate, is embedded into front template U-type groove.
The runner shape intracavitary is runner, and the side runner of runner passes through the U-shaped plate of runner ejection plate.
The beneficial effects of the utility model are：By the way that runner ejection plate is embedded into front template, reduce flow channel length, simultaneously
Simplify mould structure, during die sinking under gravity and effect of inertia, runner departs from runner shape chamber, and runner ejection plate is in spacing guide screw
Runner is taken out of under effect, and product is broken with connecting passage, runner Automatic-falling under gravity improves production efficiency
And automatization level.

Embodiment
Refering to shown in Fig. 1-4, a kind of template die runner Automatic-falling structure of injection mold three, including panel 1, flange 2, sprue bushing
3rd, front template 4, lead 5 and runner shape chamber 6, the panel 1 are connected with flange 2, and the sprue bushing 3 is located in panel 1 and flange 2
Connection；The lead 5 is on panel 1, and the front template 4 runs through on lead 5, before the runner shape chamber 6 is located at
Sprue bushing 3 is connected in template 4；The front template 4, which is provided with U-type groove 41, the U-type groove 41, is provided with corresponding runner ejection plate 7, institute
State to run through on runner ejection plate 7 and be connected provided with spacing guide screw 8 with panel 1.
The runner ejection plate 7 is U-shaped plate, is embedded into the U-type groove 41 of front template 4.
It is runner 9 in the runner shape chamber 6, the side runner 91 of runner 9 passes through the U-shaped plate of runner ejection plate 7.
In practical application, after the completion of injection, molding is shed, is molded, front template 4 drives 1 point of runner ejection plate 7 and panel
From, runner 9 departs from panel 1 and sprue bushing 3, because runner ejection plate 7 is stopped by the advance setpoint distance of spacing guide screw 8, and
The reverse push of runner ejection plate 7 lives the side runner 91 of runner 9, and runner 9 departs from from the runner shape chamber 6 in front template 4, and between product
Connection cut-out, is separated, under gravity, runner 9 is shed in material-containing basket at the U-shaped plate opening of runner ejection plate 7 with product,
Runner is removed without manually or mechanically hand, production efficiency is improved, realizes automated production.
It is described above, embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any change or replacement expected without creative work should all be covered and are defined in the new protection domain of this practicality.
