But, the injection mold in above-mentioned patent, its ejecting mechanism be by special driving mechanism as air cylinder driven, after mould is opened completely, drive push rod outwards to eject the workpiece after shaping by this driving mechanism.
Utility model content
Technical problem to be solved in the utility model is to provide simple in structure for the above-mentioned state of the art, and the mould opening force that can use mould in die sinking carries out the injection mold of liftout.
For achieving the above object, the utility model provides following technical scheme:
A kind of injection mold, includes cover half and the dynamic model that can separate or close up with described cover half, is provided with the first die cavity on described cover half, on described dynamic model, be provided with the second die cavity, the first described die cavity and the second die cavity can form the die cavity that holds workpiece in the time that described dynamic model and cover half close up, wherein
In described the first die cavity, be provided with Workpiece fixing plate, on described cover half, be circumferentially provided with some slide blocks along described the first die cavity, described slide block includes a side relative with dynamic model and a side relative with cover half, and described Workpiece fixing plate is bearing on the side that described slide block is relative with dynamic model
On described dynamic model, be fixed with Angle Pin, on described slide block, offer inclined hole, described Angle Pin one end is fixed on dynamic model, and the other end can be against on described cover half through described inclined hole in the time that described cover half and described dynamic model close up.
As a further improvement on the present invention, described inclined hole is through hole, described inclined hole has two openings that vary in size, be opened in respectively described slide block with respect on a side of dynamic model and the side with respect to cover half, described Angle Pin comprises Part I and the Part II that footpath, cross section is different, and described Part I and described Part II link into an integrated entity and be formed with step surface at both connecting portions.
As improvement, an opening of described inclined hole is oval, be arranged on the side of described slide block with respect to dynamic model, another opening of described inclined hole is circular, be opened on the side of described slide block with respect to cover half, the size of described circular open is less than the size of elliptical openings and the size of described step surface.Adopt this structure, slide block both can be slided on described Angle Pin, meanwhile, in the time that slide block slides into step surface, can be subject to again the limiting card of step surface on step surface, thereby drive whole slide block along with this Angle Pin rises together by the rising of Angle Pin.
Compared with prior art; the utility model has the advantage of: on injection mold, be provided with Angle Pin; Angle Pin one end is fixed on dynamic model; the other end is socketed with slide block; slide block upper support has Workpiece fixing plate; by this structure; can be in the time of die sinking; the mould opening force that utilizes dynamic model and cover half to separate; drive Angle Pin to slide with respect to cover half, because thrust slide supporting is on the step surface of described Angle Pin, and then can be with movable slider to separate with cover half; thereby Workpiece fixing plate is separated with cover half relatively, realized liftout.Injection mold of the present utility model has utilized the mould opening force of dynamic model and cover half to realize the liftout to workpiece, has saved special liftout drive unit, simple in structure, provides cost savings again.

The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As Figure 1-Figure 5, the present embodiment is a kind of injection mold, include cover half 1 and the dynamic model 2 that can separate or close up with described cover half, on described cover half, be provided with the first die cavity 1.1, on described dynamic model, be provided with the second die cavity 2.1, the first described die cavity and the second die cavity can form and hold the die cavity 3 that workpiece is placed in the time that described dynamic model and cover half close up, wherein
In described the first die cavity, be provided with Workpiece fixing plate 4, on described cover half, be circumferentially provided with some slide blocks 5 along described the first die cavity, described slide block includes a side relative with dynamic model and a side relative with cover half, and described Workpiece fixing plate is bearing on the side that described slide block is relative with dynamic model
