Description
Technical field
The present invention relates to mould applications, particularly to a kind of secondary ejecting mechanism.
Background technology
When the shape of finished product to be removed from mould is special, or according to requirement during volume production, if once pushed up
After going out, finished product still in die cavity, or cannot Automatic-falling when it is necessary to be further added by once ejection action, such top
Go out action and be Double-ejection.Double-ejection can allow and eject flow process smoothization, for the product that some ejection stroke demands are larger
Product, can reduce, using Double-ejection, the power that thimble applies in ejection, it is to avoid cause the defect of product during ejection.
In prior art, with regard to secondary ejection mechanism for mold or device, mainly there is the Double-ejection machine using grab form
Structure, using the secondary ejecting mechanism of resin shutter, using the secondary ejecting mechanism of form of springs, wherein, the two of grab form
Secondary ejecting mechanism is more complicated, and the secondary ejecting mechanism using resin shutter easily weares and teares, and ejection was easily lost efficacy and ejecting force
Little, son is typically entered with single-unit activity using the secondary ejecting mechanism of form of springs and does local Double-ejection, but after spring is compressed
Due to not having starting power it is impossible to synchronously eject with product, breaking of product is caused to pull.
In consideration of it, being necessary that the secondary ejecting mechanism to prior art is perfect further.
Content of the invention
In order to solve problem of the prior art, embodiments provide that a kind of part is less, structure is very simple, system
Make low cost, process and assemble cycle is short, safeguard easy secondary ejecting mechanism.Described technical scheme is as follows:
Embodiments provide a kind of secondary ejecting mechanism, described secondary ejecting mechanism includes being sequentially connected and is arranged at mould
Lower roof plate that the plastic ompression molding machine knock-pin of base plate is connected with described plastic ompression molding machine knock-pin, it is arranged at described lower roof plate side
Swivel plate, the middle top board being arranged at described swivel plate end, the upper plate being arranged on described middle top board, it is arranged at described middle top
The Double-ejection of plate side is spacing, be arranged on described upper plate spring guide pillar and spring, it is arranged at described lower roof plate side
Travel switch, be arranged at described lower roof plate end top board spacing, through described upper plate, described middle top board and described under
The top of top board setting is excellent, be arranged on the described screw pushing up between rod one end and die bottom plate, be arranged on the excellent other end in described top
Jacking block, another screw being arranged between the excellent and described jacking block in described top, the push rod being arranged on described middle top board；Described push rod
Run through moving platen, support block and the setting of described upper plate.
Technical scheme provided in an embodiment of the present invention has the benefit that
Compared with existing secondary ejecting mechanism, part reduces the present invention, and structure is very simple, low cost of manufacture, process and assemble
Cycle is short, safeguards simple.
Brief description
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, will make to required in embodiment description below
Accompanying drawing be briefly described it should be apparent that, drawings in the following description are only some embodiments of the present invention, for
For those of ordinary skill in the art, on the premise of not paying creative work, other can also be obtained according to these accompanying drawings
Accompanying drawing.
Fig. 1 is the structure structural representation of Double-ejection machine provided in an embodiment of the present invention；
Fig. 2 is the working state figure one of secondary ejecting mechanism provided in an embodiment of the present invention；
Fig. 3 is the working state figure two of secondary ejecting mechanism provided in an embodiment of the present invention.
Specific embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to embodiment party of the present invention
Formula is described in further detail.
Embodiments provide a kind of secondary ejecting mechanism, be applied in mould, referring to Fig. 1, this mould includes
Guide pillar 3, the guide pin bushing 4 being arranged on guide pillar 3 and upper lid that the solid plate 2 that cover plate 1 is connected with upper cover plate 1 is connected with solid plate 2
Plate 1 matches the base plate 5 of setting, the support block 6 being arranged on base plate 5, the moving platen 7 being arranged on support block 6；
The plastic ompression molding machine knock-pin 8 that this secondary ejecting mechanism includes being arranged on base plate 5 is connected with plastic ompression molding machine knock-pin 8
Lower roof plate 9, it is arranged at the swivel plate 10 of lower roof plate 9 side, is arranged at the middle top board 11 of swivel plate 10 end, is arranged at middle top board
