Description
Technical field
The utility model is related to the Curve guide impeller technical fields of injection mold ejection stripping device, more particularly to a kind of letter
Easy secondary ejecting mechanism.
Background technology
In the prior art, the ejecting mechanism of injection mold is called demoulding mechanism, in each cycle of injection molding,
Plastic product must be taken out from mold cavity, and it is ejecting mechanism to complete the mechanism that this takes out plastic action, ejector
The main function of structure has three, and 1, in die sinking, ensure that plastic product and gating system of material nondeforming smoothly take off from mold
Go out；2, after plastic product and condensate etc. are removed from the molds, when molding, ensures that ejecting mechanism correctly resets；3, for mould
The structure of core-pulling mechanism is equipped in tool, at this moment ejecting mechanism can be used as the power source of core-pulling mechanism.
The mechanism that just plastic can be made reliably to demould using projecting motion twice is known as two-step ejecting demoulding mechanism, and use is this
Mechanism is primarily to adapt to the needs (it is required that plastic voluntarily falls) or certain by a projecting motion of white dynamic metaplasia production
Afterwards, plastic is still unable to the occasion of ejection die.Sometimes using secondary demolding mechanism is avoided once de- to ensure plastic part quality
Plastic stress excessive generation rupture when mould.There are two these mechanisms are general or two groups of ejection strokes have the release zero of certain difference
Part needs the release part stopping in advance action that stroke is smaller if they are acted simultaneously；If they are acted when different,
It is required that the release part lost motion that stroke is larger.Therefore, secondary demolding mechanism must be provided with the device that stroke is released in control.
It is common it is pneumatic, surge two-step ejecting demoulding mechanism, since demoulding power needs are provided separately, it is complicated and
Cost is high, some easy spring structures, then is limited to that spring action is not firm, and spring is easy failure, needs in time
It replaces, thus is also not suitable for promoting and applying.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of simple secondary ejector mechanism thereof, the machine
Structure is ingenious in design, and production cost is low, overcomes the unstable disadvantage of single spring secondary stripping action, using lever principle by
The active force that injection molding machine ejection applies, stripping result are good.
In order to achieve the above object, the technical solution adopted in the utility model is：A kind of simple secondary ejector mechanism thereof, including
Push rod and the first mandril, push rod connect push plate, and the first mandril passes through mold insert, push rod and the first mandril be arranged at thimble panel with
Between Ejector Retainer Plate, first jack end is equipped with end cap, is equipped with and is placed in the cavity between end cap and thimble panel
First spring of the first mandril is machined with cavity on the Ejector Retainer Plate, mounting-fixing base in the cavity, the rotation in fixed seat
Shaft connects wraping plate, and wraping plate both ends are movably connected with the first mandril and the second mandril, the height of the second mandril and thimble panel
Difference is the displacement difference of wraping plate.
Further, wraping plate both ends as described above are respectively articulated with the first mandril and the second mandril.
Further, wraping plate both ends as described above are respectively fixedly connected with two columns for carrying spherical surface.
Further, column as described above is contacted with the first mandril and the second mandril face respectively.
Further, wraping plate as described above is provided with second spring in second mandril one end.
Further, mold insert as described above is installed in B plates and is connected with push plate at the frame of mold insert.
Compared with prior art, the utility model has the beneficial effects that：The present apparatus is ingenious in design, easy for installation, is produced into
This is low, overcomes the unstable disadvantage of single spring secondary stripping action, is applied by injection molding machine ejection using lever principle
Active force, stripping result are good.

Specific implementation mode
Be described in detail with reference to attached drawing with reference to embodiment, so as to the technical characteristics of the utility model and advantage into
Row deeper into annotation.
As shown in Figs 1-4, a kind of simple secondary ejector mechanism thereof of the utility model, including push rod 4 and the first mandril 5, push away
Bar 4 connects push plate 2, and the first mandril 5 passes through mold insert 3, and push rod 4 and the first mandril 5 are arranged at thimble panel 7 and Ejector Retainer Plate 8
Between, 5 end of the first mandril is equipped with end cap, is equipped in the cavity between end cap and thimble panel 7 and is placed on the first top
First spring 11 of bar 5 is machined with cavity on the Ejector Retainer Plate 8, mounting-fixing base 13 in the cavity, in fixed seat 13
Axis connection wraping plate 12 is rotated, so that wraping plate 12 is freely rotated along rotary shaft, 12 both ends of wraping plate are movably connected with the first top
The difference in height of bar 5 and the second mandril 10, the second mandril 10 and thimble panel 7 is the displacement difference of wraping plate 12, avoids thimble and mold
The interference of plate causes the damage of component.
Further, 12 both ends of wraping plate are respectively articulated with the first mandril 5 and the second mandril 10, as shown in Figure 2.
