Technical field
Mould technical field is the utility model is related to, more particularly to a kind of secondary ejecting mechanism of injection mold.
Background technology
Plastics injection mould is the instrument for producing plastic products, using very extensive.In plastic products injection molding, it is
The demoulding order of plastic products should be controlled by meeting the needs of moulding process.Sometimes because plastic parts shape is special or the production automation
Need, after once projecting motion is stripped, plastic is still hard to that Automatic-falling is taken out or be unable to from die cavity, it is necessary to is further added by one
Secondary demoulding projecting motion, can just be stripped plastic；It is excessive sometimes for plastic stress when avoiding once being stripped release, also using two
The secondary demoulding is released, and to ensure the quality of plastic, this kind of mould emptier is referred to as two-step ejecting device.Traditional two-step ejecting device knot
Structure is complicated, and release effect is poor, and product percent defective is high, and cost is big.
Utility model content
Main purpose of the present utility model is to propose a kind of secondary ejecting mechanism of injection mold, it is intended to solves above-mentioned technology
Problem, realize that release state is steady, release effect is good, so as to reduce the scrappage of die sinking product.
To achieve the above object, the utility model proposes a kind of secondary ejecting mechanism of injection mold, including bottom plate, push away
Plate, fixed form, a push rod, secondary push rod, drive link, mold insert and pull bar, the push pedal are arranged on the bottom plate and described
Between fixed form, the push pedal includes a push pedal and secondary push plate, and a push rod is arranged in a push pedal,
The secondary push rod is arranged in the secondary push plate, and a push pedal is provided with screw towards the one side of the secondary push plate
And fulcrum block, one end that described screw one end wears the secondary push plate are arranged with spring, described drive link one end and the edge
Part is fixedly connected, and retainer is provided with the secondary push plate, is rotatablely connected in the middle part of the drive link with the fulcrum block, described
One end of drive link is rotatablely connected with the retainer, the other end of the drive link and one of the pull bar away from the mold insert
End connection.
Preferably, the section of a push rod and the secondary push rod is disposed as circle, also, a push rod
Raised circular shape is arranged to the ejection end face of the secondary push rod.
Preferably, the drive link is cut with scissors with the fulcrum block, the retainer and the pull bar by connector respectively
Connect.
The beneficial effect of technical solutions of the utility model：In knockout course, a push pedal is moved towards fixed form and driven
Push rod up pushes away product, completes to eject for the first time, then continue to drive secondary push plate to move upwards after spring buffer, pull bar
Mold insert is pulled out into reduction frictional force from the recess of product, secondary push rod promotes product, completes Double-ejection, realizes and releases shape
State is steady, and release effect is good, so as to reduce the scrappage of die sinking product.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to the structure shown in these accompanying drawings.
Structural representation when Fig. 1 is one embodiment matched moulds of the utility model；
Fig. 2 is that the structure when embodiment of the utility model one is stripped is one；
Realization, functional characteristics and the advantage of the utility model purpose will be described further referring to the drawings in conjunction with the embodiments.
Embodiment
The utility model proposes a kind of secondary ejecting mechanism of injection mold.
In the utility model embodiment, the secondary ejecting mechanism；As depicted in figs. 1 and 2, it is including bottom plate 10, push pedal, solid
20, push rods 30 of solid plate, secondary push rod 40, drive link 50, mold insert 60 and pull bar 70, push pedal are arranged on bottom plate 10 and fixed
Between template 20, push pedal includes a push pedal 910 and secondary push plate 920, and a push rod 30 is arranged in a push pedal 910, and two
Secondary push rod 40 is arranged in secondary push plate 920, and a push pedal 910 is provided with screw 911 and branch towards the one side of secondary push plate 920
Point seat 912, one end that the one end of screw 911 wears secondary push plate 920 are arranged with spring 913, and the one end of drive link 50 is solid with mold insert 60
It is fixed to connect, retainer 921 is provided with secondary push plate 920, the middle part of drive link 50 is rotatablely connected with fulcrum block 912, drive link 50
One end be rotatablely connected with retainer 921, the other end of drive link 50 is connected with the one end of pull bar 70 away from mold insert 60.
In knockout course, a push pedal 910 is moved towards fixed form 20, drives a 30 upward ejecting product of push rod
80, completion once ejects；After a segment distance is moved in a push pedal 910, screw 911 drives spring 913 to be compressed to a certain degree
Afterwards, start to drive secondary push plate 920 to move up, while secondary push rod 40 completes Double-ejection, drive link 50 is in retainer
One end moves up under 921 drive, and its other end begins to move under phase in the presence of fulcrum block 912, is drawn so as to drive
