Back-off mechanism is taken off on straight top according to the utility model, and said pin-lift arrangement comprises a cylindrical push rod, and said push rod top is located at said straight top, and said push rod bottom connects said drive unit.
Back-off mechanism is taken off on straight top according to the utility model, and said straight top is provided with one and is used for laterally promoting the impeller of said product and the elastic component of horizontally set, and said impeller is connected to said elastic component.
Back-off mechanism is taken off on straight top according to the utility model, and said straight top is taken off back-off mechanism and also comprised a fixing protruding position part, said protruding position part and said impeller butt.
Back-off mechanism is taken off on straight top according to the utility model, said straight top also be provided with one be used to limit said elastic component shift position stop bit spare.
Back-off mechanism is taken off on straight top according to the utility model, and said drive unit comprises end needle plate and face needle plate.
Back-off mechanism is taken off on straight top according to the utility model, and said elastic component is a spring.
The utility model is through being provided with a pin-lift arrangement on injection mold, this pin-lift arrangement can move up and down, and its top is provided with top always, and the bottom is provided with a drive unit, this straight top under normal condition with the product butt.When drive unit applies pin-lift arrangement one active force, it is moved upward, then straight top promotes the product motion makes it break away from mould.Preferably, straight top is provided with one and is used for laterally promoting the impeller of product and the elastic component of horizontally set, and said impeller is connected to said elastic component.Make product whereby when upwards being pushed out, move right simultaneously, make it break away from mould fully, avoid sticking to mould and pull.
Description of drawings
Fig. 1 is that the utility model directly pushes up the cross-sectional view of taking off back-off mechanism;
Fig. 2 is the cross-sectional view of the product released state of the utility model.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Referring to Fig. 1, the utility model provides a kind of straight top of injection mold to take off back-off mechanism, this directly push up take off back-off mechanism 100 specifically be the product private side to monolateral large tracts of land back-off mould emptier, it comprises pin-lift arrangement 10 and drive unit 20.
Pin-lift arrangement 10 can up and downly be connected in injection mold, and this pin-lift arrangement 10 comprises a cylindrical push rod 11 and the straight top 12 of being located at these push rod 11 tops.Push rod 11 bottoms connect drive unit 20, and drive unit 20 is used for applying active force to push rod 11, and it can be moved up and down, and this drive unit 20 comprises superimposed end needle plate 21 and face needle plate 22.In the concrete practicality, straight top 12 butt products 30 when it is stressed when moving upward, can promote product 30 and move upward.
Among one embodiment of the utility model; Straight top 12 is provided with one and is used for laterally promoting the impeller 121 of said product 30 and the elastic component 122 of horizontally set, the elastic component 122 preferred springs that adopt, and impeller 121 is connected to elastic component 122; Accordingly; Straight top is taken off back-off mechanism 100 and also is provided with a fixing protruding position part 40, an end of impeller 121 and protruding part 40 butts, the other end and product 30 butts.If the impeller 121 stressed certain positions that move up to, in conjunction with Fig. 2, protruding position part 40 applies impeller 121 1 active force to the right; Elastic component 122 is compressed; Impeller 121 moves right simultaneously, promotes product 30 and also moves right, and makes product 30 and mold separation whereby.Preferably, straight top 12 also is provided with stop bit spare 123, and when impeller 121 returns, stop bit spare 123 can guarantee impeller 121 return fast and accurately with elastic component 122.
The sticking tiltedly difficult problem on top when the utility model has solved oblique top moulding large tracts of land back-off, thus avoid sticking to mould phenomenon such as to pull, this structure have take up room little; Manufacture craft is simple, and is not fragile, convenient for installation and maintenance; Characteristics such as mechanism kinematic is smooth and easy had both been dwindled mould specification, had reduced the joint line of product surface again; Simultaneously saved the manufacturing maintenance cost again, mould and moulding production efficiency are improved greatly.
A course of work of the utility model is described below in conjunction with Fig. 1 and Fig. 2.
Mold injection finishes, and needs products of separated 30, and impose on active force that push rod 11 one make progress through end needle plate 21 and face needle plate 22 this moment, and push rod 11 drives straight top 12 and moves up, and 12 pairs of products in straight top 30 are done upwards to promote.Meanwhile, impeller 121 receives protruding position part 40 active force to the right, moves right; Promoting product 30 whereby moves right; So motion breaks away from mould fully until product 30, and elastic component 122 produces deformation by compression simultaneously, and can take out product this moment through the exterior mechanical hand; Impose on the downward active force of push rod 11 1 through end needle plate 21 and face needle plate 22 again, until said straight top 12 and impeller 121 and elastic component 122 returns.
In sum, the utility model is through being provided with a pin-lift arrangement on injection mold, and this pin-lift arrangement can move up and down, and its top is provided with top always, and the bottom is provided with a drive unit, this straight top under normal condition with the product butt.When drive unit applies pin-lift arrangement one active force, it is moved upward, then straight top promotes the product motion makes it break away from mould.Preferably, straight top is provided with one and is used for laterally promoting the impeller of product and the elastic component of horizontally set, and said impeller is connected to said elastic component.Make product whereby when upwards being pushed out, move right simultaneously, make it break away from mould fully, avoid sticking to mould and pull.
Certainly; The utility model also can have other various embodiments; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
