Description
Technical field
The present invention relates to the injection forming mold field of sheet material, relate in particular a kind of shaping dies with anti-package limit sheet material, it can mold the anti-package limit of sheet material simultaneously, thereby have the high characteristics of forming efficiency, especially can be applied to all kinds of IMD home appliance panels of moulding, IMD pen electricity shell and IMD phone housing.
Background technology
Day by day in fashion along with electronic products such as mobile phone, notebook, digital cameras, the also steady-state growth of the demand of above-mentioned electronic product casing, the shell of present above-mentioned electronic product all is to adopt Shooting Technique to process.
But along with above-mentioned electronic product casing constantly bringing forth new ideas in appearance, the anti-package limit has all appearred in many shells, then gives thus Shooting Technique, and especially injection mold has brought challenge.
In view of this, the inventor has this case to produce for the difficulty further investigation of prior art when the moulding anti-package limit then.
Summary of the invention
The object of the present invention is to provide a kind of shaping dies with anti-package limit sheet material, its can repeatedly, full-automaticly mold sheet material and on the anti-package limit.
In order to reach above-mentioned purpose, solution of the present invention is:
A kind of shaping dies with anti-package limit sheet material wherein, comprising:
Upper die component has upper bolster, upper holding pad, binder spring, angled-lift splits, oblique impact head, guide pad, patrix spring, slide block back-moving spring and spring stop; This binder spring is arranged between holding pad and the upper bolster to hinder upper holding pad near upper bolster, this oblique impact head is fixed on the upper bolster, this oblique impact head has the first oblique surface, this patrix spring is arranged between guide pad and the upper bolster to hinder guide pad near upper bolster, this spring stop, slide block back-moving spring and angled-lift splits all are positioned at the guide pad below, this spring stop is fixed on the guide pad, this angled-lift splits has the second oblique surface, this slide block back-moving spring is arranged between spring stop and the angled-lift splits and promotes angled-lift splits and makes the second oblique surface can be close to the first oblique surface, and this angled-lift splits also is formed with the protruding grain that is used to form the anti-package limit in the opposite side bottom that forms the second oblique surface;
Lower membrane module, have die shoe, lower bolster, lower mode slider, take off plate and counterdie spring down, this lower bolster is fixed on the die shoe, this time mode slider slidably is arranged on the lower bolster and can be pushed down by upper holding pad, the groove that this time mode slider and lower bolster are formed with between when non-demoulding state and protruding is complementary; This counterdie spring is arranged on down and takes off between plate and the die shoe to take off plate under hindering near die shoe, takes off plate this under with lower bolster is inconsistent, this upper die component and lower membrane module matched moulds and this protruding and this engagement when forming die cavity.
Further, the elastic force of this patrix spring is greater than the elastic force of this counterdie spring.
Further, this upper die component also comprises binder guide pillar, binder guide groove, slide block guide post and slide block guide groove, this time membrane module also comprises and takes off the plate guide pillar and take off the plate guide groove, this binder guide pillar one end is fixed on the holding pad, the other end slidably is installed with in the binder guide groove, and this slide block guide post one end is fixed on the guide pad, and the other end slidably is installed with in the slide block guide groove, this takes off plate guide pillar one end and is fixed on down and takes off on the plate, and the other end slidably is installed with in taking off the plate guide groove.
After adopting said structure, a kind of shaping dies with anti-package limit sheet material that the present invention relates to, it is when matched moulds, at first via upper holding pad lower mode slider being carried out pressing fixes, then since the elastic force of this patrix spring greater than this counterdie spring, can accept supporting of this angled-lift splits and move to the end therefore plate is taken off in this time, because this upper die component also continues downward membrane module motion, this angled-lift splits then overcomes the elastic force of patrix spring on the one hand, overcome on the other hand the elastic force of slide block back-moving spring and slide along the first oblique surface, this moment, this angled-lift splits was along the surperficial translation of descending to take off plate for taking off plate this under, namely do the direction motion near groove, and finally form die cavity; In this process since should be protruding design feature of grain, this protruding with groove between will form the anti-package limit that is connected with die cavity.
When the demoulding, this time mode slider can move and abdicates demoulding space for the anti-package limit along lower bolster, so can easily realize the demoulding of workpiece, and under the effect of each spring, each assembly will reset to original state and be beneficial to carrying out smoothly of next moulding.
So compared with prior art, the present invention can realize the moulding to sheet material and anti-package limit structure thereof full-automaticly, and has simple to operate and characteristics easily.
