Fig. 2 is the three-dimensional structure diagram of auxiliary targeting part in reverse buckle demolding mechanism in the utility model embodiment；
Fig. 3 is the fundamental diagram of reverse buckle demolding mechanism in the utility model embodiment.
Specific embodiment
Embodiment：A kind of specific embodiment of reverse buckle demolding mechanism is present embodiments provided, the reverse buckle demolding mechanism can be used
In the demoulding of the complex product of some structures, such as the demoulding of bumper.Because in design vehicle bumper,
Mechanical property when not only being used in view of it, in addition it is also necessary to which in view of its apparent aesthetic feeling, and bumper is more wide
Greatly, and structure is complex, it is more difficult during the demoulding, particularly when its back-off face depanning, it is easy to cause the damage of outward appearance
It is bad.
As shown in figure 1, the reverse buckle demolding mechanism provided in the present embodiment, including ejection part 1 and with ejection part 1
The auxiliary targeting part 2 of mating connection.In the bumper demoulding, ejection part 1 and auxiliary targeting part 2 cooperate,
It is finally completed the demoulding of product.
Specifically, ejection part 1 includes that jacking block 11, the guide pad 12 being connected at below jacking block 11 and guide pad 12 connect
The straight push rod 13 for connecing and the push rod guide pin bushing 14 coordinated with straight push rod 13.Wherein, guide pad 12 is fixedly connected with straight push rod 13,
Connected mode can be welding or mode connects for screw.The up and down motion of straight push rod 13, directly drives the up and down motion of guide pad 12.
In the mechanism, to draw deformation jacking block, guide pad 12 is the upper table of the guide pad of T-type structure, jacking block 11 and guide pad 12 to jacking block 11
Face is to be flexibly connected, and jacking block 11 can horizontally slip relative to guide pad 12.That is, in ejection bumper product
When, in the upward ejection process of straight push rod 13, drive guide pad 12 to move up, while jacking block 11 is moved upwards, led in auxiliary
To under the guiding mating reaction of part 2, jacking block 11 is also moved left and right in the upper surface of guide pad 12 of T-type structure, realizes level side
Ejection repeatedly and retraction, are achieved in the smooth depanning in bumper product back-off face upwards.
Wherein, the angle of guide pad 12 can be adjusted as needed, to realize the direction that bumper is threaded off, because
This, the reverse buckle demolding mechanism is applicable to the bumper of different structure, and application field is wider.
Push rod guide pin bushing 14 is fixed on lower mould, and push rod guide pin bushing 14 is mainly made of brass and graphite, is had to straight push rod 13
There is lubrication, prevent straight push rod 13 from causing to wear and tear and reduce the mold use life-span during long-term use.
As shown in Fig. 2 auxiliary targeting part 2 includes the pull bar 22 that guide rail 21 and one end are connected with guide rail 21.Draw
The other end of bar 22 is fixedly connected with jacking block 11, can be attached by welding or screw between the two.Transported about 11 in jacking block
When dynamic, pull bar 22 can be simultaneously driven to be moved up and down along guide rail 21.
The spigot surface of guide rail 21 is S type structures, and when jacking block 11 is ejected, it drives pull bar 22 to be moved upwards along guide rail 21
It is dynamic, while pull bar 22 is also moved left and right in the vertical direction of guide rail 21, so as to drive jacking block 11 to bounce back or eject, complete automobile
The demoulding in bumper product back-off face.
Pull bar 22 can steadily be moved along the spigot surface of guide rail 21, and both are most common to be flexibly connected, and be exactly to draw
The one side of bar 22 is provided with the chute coordinated with guide rail 21, by chute, realizes the movable property of pull bar 22.
Certainly, the position of the spigot surface of guide rail 21 and angle are adjusted also dependent on situation, it is possible thereby to adjust pull bar 22
Translational speed, and then control time and the speed of the dropout of jacking block 11.
In the reverse buckle demolding mechanism, auxiliary targeting part 2 is arranged on the outside of mould, its preferably installation position of middle guide 21
It is set to lower mould.Also, on the whole, preferably set-up mode is：Guide rail 21 and pull bar 22 are arranged on the back side of jacking block 11, and position
In the outside of ejection part 1.In this way, while the back-off demoulding is realized, can further optimize the structure of simplified mould.
That is, the reverse buckle demolding mechanism in the present embodiment, is connected using installing to coordinate with ejection part 1 in mold exterior
The auxiliary targeting part 2 for connecing, and optimize the ejection structure of part 1, in the mating reaction of auxiliary targeting part 2 with ejection part 1
Under, while thus front to bumper and side ejection complete back-off to complete inside contracting and resetting for shaped article
The smooth demoulding in face, solves the problems, such as that product stripping is difficult.
Also, in same mould, we can install two or more in multiple positions according to actual needs
Reverse buckle demolding mechanism, maximally to optimize mould structure as far as possible, improve the presentation quality of bumper product.
Below in conjunction with Fig. 3, by taking the reverse buckle demolding mechanism at set in mould as an example, its effect is expanded on further former
Reason.
During shaping, the not upward jack-up of straight push rod 13, jacking block 11 is in location A, i.e. pull bar 22 and is located at the bottom of guide rail 21.
During the demoulding, the upward jack-up of straight push rod 13 drives guide pad 12 to move up, and guide pad 12 is upward by the jack-up of jacking block 11
Motion.Meanwhile, jacking block 11 drives pull bar 22 to be moved up along guide rail 21, because the spigot surface of guide rail 21 is S types, and by location A
When moving to B location, spigot surface is overall to be offset to upper right side.Now, pull bar 22 is moved also along guide rail 21 to upper right side, so that
Jacking block 11 is driven to move right so that jacking block 11 is ejected, and in the horizontal direction, jacking block 11 is pushed up to the right in B location equivalent to location A
Go out distance for L1, thus complete the ejection of product side.
Afterwards, straight push rod 13 continues up jack-up, and other parts are moved in succession, and jacking block 11 reaches location of C.From B
Location of C is put, the spigot surface of guide rail 21 is overall to be offset to upper left side, therefore jacking block is also moved to the left while upper shifting, that is, exist
In horizontal direction, in location of C relative to B location, the distance being moved to the left is L2 to jacking block 11, thus completes the retraction of jacking block 11.
By the ejection in the horizontal direction of jacking block 11 and retraction, the back-off face of product dexterously can be carried out into the demoulding,
Complete product trip action.
Certain above-described embodiment is familiar with this only to illustrate technology design of the present utility model and feature its object is to allow
The people of technology will appreciate that content of the present utility model and implements according to this, can not limit protection model of the present utility model with this
Enclose.Equivalent transformation or modification that all Spirit Essences according to the utility model main technical schemes are done, should all cover in this reality
Within new protection domain.
