Description
Technical field
The present invention relates to a kind of decorative panel injection molds with variable-angle pitched roof mechanism, belong to plastic mould field.
Background technique
Currently, the plastic decorating part on automobile mostly uses injection mold to be processed greatly, such as the dress of automobile front beam
Plaque etc. is ejected at the back side of decorative panel there are many back-off for assembly in product according to product shape and function analysis
Before, it needs to demould back-off.Such back-off demoulding of the prior art mostly uses greatly the ramp-roof structure with oblique slide, and movement is flat
Surely, demoulding is reliable.But according to the shape of automobile front beam, also arc-shaped bent angle shape, the position are fallen at the both ends of decorative panel
The setting of also arc-shaped or inclined-plane is detained, there is oblique angle, above-mentioned ramp-roof structure cannot achieve normal demoulding, and therefore, it is necessary to set
Count a kind of pitched roof mechanism of variable-angle.
Summary of the invention
The purpose of the invention is to overcome prior art, provide it is a kind of using straight top and oblique top cooperation, simultaneously
Angle change is realized in swingable adjusting, the decorative panel injection molding with variable-angle pitched roof mechanism for deviating from arc back-off normally
Mold.
The technical solution of decorative panel injection mold of the present invention with variable-angle pitched roof mechanism is: multiple including stationary mould for mould

Gap between moving template and solid plate constitutes die cavity, and material mouth passes through solid plate and is connected to die cavity, injecting products in die cavity, on product
It is formed with inclined-plane back-off, it is characterised in that adjacent straight mandril and inclined-plane pedestal are set on the top plate, are arranged on inclined-plane pedestal
Inclined-plane guide block is formed with guide rod on inclined-plane guide block, angle ejector rod is arranged on guide rod, and oblique top bullet is arranged between guide rod and angle ejector rod
Slanted kicking block is arranged on angle ejector rod for spring, and slanted kicking block is matched with inclined-plane back-off, and the top of straight mandril is in contact with product, in oblique top
Gradient guide pin is arranged in the top of bar, gradient guide groove is arranged on the top of straight mandril, gradient guide pin is matched with gradient guide groove.
The invention discloses a kind of decorative panel injection mold with variable-angle pitched roof mechanism, main feature is included in top
Adjacent straight mandril and inclined-plane pedestal are set on plate, inclined-plane guide block is set on inclined-plane pedestal, is formed with guide rod, guide rod on inclined-plane guide block
On be arranged angle ejector rod, and oblique top spring is set between guide rod and angle ejector rod, slanted kicking block, slanted kicking block and inclined-plane are set on angle ejector rod
Back-off matches, and the top of straight mandril is in contact with product, gradient guide pin is arranged on the top of angle ejector rod, on the top of straight mandril
Gradient guide groove is set, and gradient guide pin matches with gradient guide groove, when demoulding, is moved upwards by 4 oil cylinders drive top plates, top plate band
It moves straight mandril and inclined-plane pedestal while jacking up, inclined-plane pedestal drives inclined-plane guide block, and inclined-plane guide block drives angle ejector rod to make tiltedly through guide rod
To ejection, and under the cooperation of gradient guide pin and gradient guide groove, while making inclined-plane climbing, so that slanted kicking block is detached from inclined-plane back-off, tiltedly
Top spring helps out, and can finely tune the oblique top position of angle ejector rod, guarantees that slanted kicking block and inclined-plane are buckled to not detent, is detached from suitable
Benefit, straight mandril withstand on the product back side, by outside product ejection die together with the mandril of mold, complete entire stripping process.We
Case uses a kind of straight mandril belt variable gradient structure, and angle ejector rod is moved upwards and bottom spring by the inclined-plane guide block on top plate
Under collective effect, moved by straight mandril variable-angle guide rail (gradient guide groove), to push inclined-plane of the slanted kicking block by shaped article
It is buckled to oblique ejection, guarantee smoothly completes demoulding, and the technological deficiency of integration demoulding can not be accomplished by solving this former class formation,
With significant progress.
Decorative panel injection mold with variable-angle pitched roof mechanism of the invention, the inclined-plane pedestal side setting stop
Position block, stop block are in contact with angle ejector rod bottom surface, act on angle ejector rod start stop bit, prevent angle ejector rod from falling off.The gradient is led
The gradient a of slot is 24 ° -36 °, and the gradient b of the inclined-plane pedestal is 15 °, under the cooperation of gradient guide groove and inclined-plane pedestal,
It is moved by straight mandril variable-angle guide rail, the structure that 36 ° of wide-angle climbings are detached from back-off can be achieved in maximum.
