Technical field
The utility model belongs to injection forming equipment technical field, more particularly to a kind of demoulding dress for injection molding
Put.
Background technology
During injection molding works, the glue part demoulding is last link in process of injection molding, quality of mold release
Quality will determine the quality of glue part.At present, existing stripping means mostly use the thimble demoulding, if it is more multiple then to run into shape
Miscellaneous mould, then need multiple thimbles, and construction is sufficiently complex, considerably increases equipment cost；In addition, existing mould emptier is big
It is required for using actuating unit with matching to provide power for it, not only increases production cost, and considerably increases and set
Meter assembly difficulty, difficulty is brought to production.
Chinese patent notification number discloses a kind of injection molding stripper apparatus for the utility model of CN204820204U, including
Be horizontally set on two chutes of cover half both sides, slided in each chute and be arranged with a L-type demoulding arm, L-type demoulding arm it is perpendicular
Bar is horizontally disposed with, and a demoulding hole being engaged with the cross bar of L-type demoulding arm is provided with dynamic model, is provided with the inside of dynamic model and L
The stripping station that the cross bar of type demoulding arm is engaged, the cross bar of L-type demoulding arm is extended at stripping station through demoulding hole, L-type demoulding arm
Montant slide be fastened in chute.The utility model is using the L-type demoulding arm for being arranged on cover half both sides, you can by glue part from mould
Deviate from tool, construction is relatively simple, reduces equipment cost, but such scheme also has certain defect：The L-type demoulding of both sides
Arm applies active force to the two ends of glue part, glue part is come off from injection molding, but due to the now firm cooling shaping of glue part not
Long, the two ends only to glue part apply external force, easily tilt glue part two ends, deform upon.
Utility model content
The purpose of this utility model is providing a kind of stripper apparatus for injection molding, is taken off with solving existing stripper apparatus
Easily make the problem of glue part deformation during mould.
In order to achieve the above object, base case of the present utility model is：It is for the stripper apparatus of injection molding including fixed
Dynamic model, stripper plate, moving clamping plate and piston cylinder that mould is matched with cover half, the piston rod of the piston cylinder are connected with moving clamping plate；
The upper surface of the moving clamping plate is provided with core, and dynamic model is set on core and is fixedly connected on the upper surface of moving clamping plate；Institute
The upper surface for stating dynamic model is provided with groove, and air bag is provided with groove；The stripper plate is located on dynamic model, and stripper plate is with core activity even
Connect；The dynamic model is provided with the first through hole connected with groove, and moving clamping plate is provided with the second through hole connected with first through hole；
Breather pipe is connected with the air bag, breather pipe passes through first through hole, the second through hole, the other end of breather pipe and the chamber of piston cylinder
Communication chamber.
The operation principle of this base case is：When injection molding needs injection, dynamic model is operated, dynamic model is moved to cover half
Lower surface, stripper plate is closed with cover half, now toward injected plastic melt in the die cavity of injection molding.Plastic melt is cooled and solidified
Afterwards, dynamic model is operated, makes dynamic model away from cover half.Because the piston rod of piston cylinder is connected with moving clamping plate, dynamic model is fixedly connected on dynamic
The upper surface of baffle plate, moving clamping plate is together moved therewith when dynamic model is moved, and drives piston rod to be slided up and down in piston cylinder；It is dynamic
Mould during away from cover half, the gas in piston rod compression piston cylinder, under the effect of the pressure, gas in piston cylinder leads to
Cross breather pipe to enter in air bag, air bag gradually expands, and is expanded to rear gasbag to a certain degree by stripper plate jack-up, and stripper plate will be arranged
Glue part ejection on core, now completes the glue part demoulding.Beginning is molded next time when, dynamic model is close to cover half, piston rod
Away from piston cylinder, the air pressure reduction in piston cylinder, because air bag is connected with piston cylinder, in the presence of air, air bag is crushed,
Restore to the original state, the height of stripper plate declines, and returns to the state contacted with dynamic model.
The beneficial effect of this base case is：The size of air bag expands or reduces with the action process of dynamic model, note
Dynamic model is separated with cover half after the completion of modeling, and stripper plate jack-up, stripper plate are applied a upward power, make to take off by air bag expansion to glue part
Template splits away off from core.The demoulding is completed by the action process of dynamic model, is not required to additionally set independent actuating unit, dropped
The difficulty of low production cost and equipment.In addition, carrying out the demoulding, stripper plate and glue part contact area to glue part using stripper plate
Greatly, then the lifting surface area of glue part is big, when stripper plate applies active force to glue part, glue part Omnibearing even stress, it is not easy to occur
Deformation.
Further, the groove is provided with two, is respectively provided at the both sides of dynamic model upper surface.Groove is provided with two, groove
Air bag is inside equipped with, the air bag of both sides expands demoulding plate level jack-up simultaneously during the demoulding, it is to avoid inclining occurs in stripper plate, it is impossible to
Fitted with glue part completely, make glue part unbalance stress, cause stripping result not good.
Further, the dynamic model is respectively provided on two sides with third through-hole, and spring is provided with third through-hole, and spring is fixed and connected
It is connected between fixed clamping plate and stripper plate.When stripper plate is fitted with dynamic model, spring in a state of nature, was not both elongated or not pressed
Contracting.When the demoulding is completed, air bag expansion, spring elongation, stripper plate is in by the state of jack-up, when starting to be molded next time, is moved
Mould is close to cover half, and under the pulling force of spring, stripper plate is close to dynamic model, stripper plate compressing gasbag, accelerates the speed of deflated balloon
Degree.Meanwhile, the setting of spring also helps the reset of stripper plate.
Further, the side wall of the piston cylinder is provided with passage, and passage is provided with stopper.Stopper is opened, can be with
By passage toward being filled with air in piston cylinder or releasing air in piston cylinder, so that the gentle intracapsular gas of regulating piston cylinder
Pressure, makes the degrees of expansion of air bag meet actual demand.
