Description
Technical field
The utility model relates to a kind of mould, in particular for a kind of Mold Core-pulling Mechanism of the concave, convex moulding plastic part demoulding with holes.
Background technology
When moulding has side concaveconvex structure or plastic with holes, place mandrel in concavo-convex forming part or the hole after the moulding and will hinder the plastic demoulding, adopt and manually loose core, the power of loosing core is little, and inefficiency is for raising the efficiency many employing machineries or hydraulic structures.The most concaveconvex structures and the position in hole all accompany certain angle with the direction of die sinking; in the die cavity domestic demand core of a plurality of different angles is set, adopts for the mould emptier of this complicated model assistant cylinder or hydraulic cylinder or mechanical mechanism are set in the die cavity side more.
As the patent No. is 200520010200.1, name is called a kind of automatic side core-drawing mechanism, comprise top clamping plate, cover half frame, the dynamic model frame, its improvements are: be connected with driving lever on described top clamping plate, the epimere of driving lever is parallel with the die sinking direction, the lower end of driving lever is a sliding piece, sliding piece and die sinking direction are angle, and sliding piece matches with the hole on the movable sliding block, and an end of slide block is connected with an end of moving core; Automatic side core-drawing mechanism of the present utility model, the drive core-pulling mechanism is finished and is detached the moving core action synchronously when the die opening mechanism die sinking.This automatic side core-drawing mechanism complex structure, the cost height, the time of finishing demoulding work process need is long, the mould structure complexity.
Summary of the invention
The utility model has solved in the prior art for the shortcoming of the concave-convex part demoulding with holes difficulty, and a kind of Mold Core-pulling Mechanism that can realize the core demoulding in die sinking simultaneously is provided.
Another purpose of the present utility model provides the low Mold Core-pulling Mechanism of a kind of cost simple in structure.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of Mold Core-pulling Mechanism, comprise the patrix that is fixed with pull bar, patrix is provided with the slide block that band is loosed core, wherein, be installed with the pull bar guide pillar in the described patrix, the top of pull bar guide pillar is fixed with the top frame, and the top frame is provided with Angle Pin and T shape piece; The end of Angle Pin is a crotch shape, and the end of T shape piece is step-like hypotenuse; Corresponding Angle Pin be the sub-assembly of slide block I and slide block II, the side of slide block II is provided with the concave shaped cavity that matches with the end of Angle Pin, slide block I is provided with the I of loosing core; Corresponding with T shape piece is slide block III, the hypotenuse of the side of slide block III for matching with the end of T shape piece, and slide block III is provided with the II of loosing core.Angle Pin is with the action simultaneously of T shape piece, pull bar stretches out, the top frame that is provided with Angle Pin and T shape piece is risen along the pull bar guide pillar, the concave shaped cavity of slide block II is hooked in the crotch shape end of Angle Pin during matched moulds, the top frame rises and drives tool guide pillar and the rising of T shape piece, the sub-assembly of Angle Pin pulling slide block I and slide block II, and the passage that makes it to tilt in patrix rises, the I of loosing core that drive links to each other with slide block I deviates from, and slide block III makes the II of loosing core deviate under the promotion of angled slide block; The end of T shape piece is a wedge shape, and the end of T shape piece promoted slide block III gradually and makes the position that II arrives to be needed of loosing core when the top frame fell.
Described top frame is connected on the other end of pull bar, and the outlet limit of patrix top shoe II is provided with limited block, is provided with stopper slot in the corresponding position of slide block II; The exit of patrix top shoe III is provided with latch segment.For saving the time of the demoulding, in the exit of slide block II and slide block III limited block and latch segment are set, after the necessary distance of loosing core, do not continuing action, also shortening looses core reenters the time in precalculated position.
As preferably, the concave shaped cavity base portion of described slide block II is provided with spring.When the end of Angle Pin enters in the concave shaped cavity of slide block II,, when being connected with slide block II, can not deviate from Angle Pin because the existence of spring makes the crotch shape end of Angle Pin be subjected to the tensile force of spring.
As preferably, described slide block I is connected by the buckle structure that cooperatively interacts with slide block II, and the connecting portion of slide block II is a convex body, and the connecting portion of slide block II is an inner groovy, and convex body is embedded in the inner groovy.Slide block I and slide block II separate, and adopt this buckle that cooperatively interacts to connect, and can simplify and change the process of loosing core and adjusting the position of loosing core, and adapt to the needs of multiple forming part.
The side of described slide block III is provided with chute, is provided with gag lever post with the corresponding position of the chute of slide block III on the patrix.The sliding trace that the structure that adopts chute to match with gag lever post can be controlled slide block III makes the motion of the II of loosing core more accurate, can not produce damage to the part after the moulding.
More smooth and easy for guaranteeing the slip of gag lever post on chute, as preferably, the end of described gag lever post be a sphere.
The position of wearing the pull bar guide pillar on the described patrix is with the guide pillar guide pin bushing.The guide pillar guide pin bushing reduces the wearing and tearing when motion of pull bar guide pillar, has increased service life.
The beneficial effects of the utility model are: the demoulding that realizes core in die sinking has improved efficient and has reduced the working time, adopts the Angle Pin of determining angle to match with slide block, and gag lever post matches with chute on the slide block, the loose core precision of process of assurance; Position and tension force when spring assurance Angle Pin in the slide block and the recess on the slide block match; Shorten the sliding distance of limited block and latch segment slide block, saved the time.
