Description
Technical field
Injection mold field is the utility model is related to, more particularly, to a kind of reverse buckle demolding mechanism.
Background technology
Injection molding is to produce a kind of processing method used during some complex-shaped parts in batches.Refer specifically to melt heated
The material of change injects die cavity, after cooling and solidifying, obtains products formed.Injection mold is a kind of instrument for producing plasthetics；
It is to confer to the instrument of plasthetics complete structure and accurate dimension.Injection mold is typically made up of dynamic model and cover half two parts, is moved
Mould is arranged on the moving die plate of injection (mo(u)lding) machine, and cover half is arranged on the fixed form of injection (mo(u)lding) machine.In injection moulding
Dynamic model and cover half closure form running gate system and die cavity, and dynamic model and cover half separation are to take out plastic products during die sinking.
Although the structure of mould is according to plastics variety and performance, the shape of the plastic products and type of structure and injector
It is ever-changing Deng different, but basic structure is consistent, i.e., mainly by running gate system, forming part, gas extraction system, temperature control
System and ejection system composition.Wherein running gate system and forming part be with the direct contact portion of plastics, and with plastics and product
And change, it is most complicated in mold, change is maximum, it is desirable to process finish and precision highest part；Running gate system refers to mould
Runner section before expecting from nozzle into die cavity, including sprue, cold slug well, runner and cast gate etc..Forming part refers to structure
Into the various parts of article shape, including dynamic model, cover half and die cavity, core, curved lever and exhaust outlet etc..
During plasthetics is prepared by way of injection molding, the knockout course of plasthetics seems particularly heavy
Will, the mould emptier of injection mold, which is designed to quality, can directly affect the Forming Quality of plasthetics.Present many plasthetics
Back-off is both provided with, because back-off takes shape in the inner side of plasthetics, its knockout course is complex, its corresponding ingot stripper
Structure design is also particularly important.Prior art is often by the back-off and forming blocks of plasthetics by the way of forced demoulding
Depart from, and for the higher plasthetics of required precision, the mode of forced demoulding is difficult to be applicable.
It is a plastic component structure as shown in Figure 1, the plastic 111 is provided with buckle 112.After being molded due to plastic 111, buckle
112 are tipped upside down on core rod, and plastic can be damaged by the way of forced demoulding, it is therefore desirable to are designed a kind of mould emptier, made plastic
It is stripped in the case where not damaging.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of reverse buckle demolding mechanism, is intended to make by the mould emptier
Plastic is smoothly stripped.
Technical scheme is used by the utility model solves above-mentioned technical problem：A kind of reverse buckle demolding mechanism, including cunning
Block, core rod and cylinder component, are the part forming area of plastic between described sliding block and core rod, and described cylinder component can drive
Movable slider lateral translation, in addition to push rod component, the mold insert that is connected with plastic, oblique guide hole is provided with described sliding block, it is described
Mold insert is in rod-like structure and is movably arranged in oblique guide hole, and the aperture of described oblique guide hole is located on the sidepiece of sliding block, described hole
Limited block is provided with mouthful, described limited block is bolted on sliding block, and bullet is provided between described limited block and mold insert
Spring, described spring one end are connected with limited block, and the described spring other end is against on mold insert, and described push rod component can be upward
Eject plastic；
Plastic drives sliding block by described cylinder component during demoulding, first, and side direction translates forward, is connected with plastic
Mold insert remain stationary as because of the effect of spring force, then plastic is ejected by described push rod component upwards.
Further improved as the utility model, described push rod component includes guide pad, push rod and drive device, described
Push rod tilt set up, described push rod upper end splice on core rod, the lower end of described push rod is flexibly connected with guide pad, institute
Chute is provided with the guide pad stated, described drive device is connected with push rod, and described drive device can drive push rod lower end edge
Slide, after described push rod slides, its is skewed to can be changed to vertical shape, so as to eject plastic upwards.
Compared with prior art, the utility model has the advantage of simple in construction, reasonable in design, sliding block relies on cylinder component
Driving force side direction translates forward, mold insert also has the trend of the translation of side direction forward, but due in the oblique guide hole on sliding block
There is provided spring, and during sliding block translates, mold insert is because of the reaction force by spring, therefore mold insert can remain stationary as,
So as to allow plastic during demoulding, buckle will not be damaged.
Plastic drives sliding block by cylinder component during demoulding, first, and side direction translates forward, the mold insert being connected with plastic
Because the effect of spring force remains stationary as, then plastic is ejected by push rod component upwards.

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining this
Utility model, it is not used to limit the utility model.
As shown in Figure 1 to Figure 3：A kind of reverse buckle demolding mechanism, including sliding block 1, core rod 2 and cylinder component, sliding block 1 and core rod
It is the part forming area of plastic 111 between 2, cylinder component can drive the lateral translation of sliding block 1, in addition to push rod component 4 and modeling
The mold insert 5 that part 111 connects, sliding block 1 is interior to be provided with oblique guide hole 6, and mold insert 5 is in rod-like structure and is movably arranged in oblique guide hole 6, oblique guide hole
6 aperture is located on the sidepiece of sliding block 1, limited block 7 is provided with aperture, limited block 7 is bolted on sliding block 1, spacing
Spring 8 is provided between block 7 and mold insert 5, the one end of spring 8 is connected with limited block 7, and the other end of spring 8 is against on mold insert 5, push rod group
Part 4 can eject plastic 111 upwards；
Plastic 111 drives sliding block 1 by cylinder component during demoulding, first, and side direction translates forward, is connected with plastic 111
