Abstract
The invention discloses a molding and inclined-pushing mechanism, which comprises a mold, a plastic part, a mold cavity plate, a mold core plate, an inclined push rod and a support plate, wherein the plastic part is arranged in a mold cavity of the mold; the mold cavity plate is arranged at the bottom of the mold; the mold core plate is arranged at the bottom of the mold cavity plate; the upper end of the inclined push rod penetrates through the mold cavity plate and the mold core plate and then is arranged in the plastic part; and the lower end of the inclined push rod is fixedly arranged on the support plate. According to the molding and inclined-pushing mechanism, through the arrangement of the inclined push rod, the plastic part is ejected from the mold when the mold is opened; demolding is convenient and fast; the structure is simple; meanwhile, the dimension accuracy of the plastic part can be improved; and the appearance requirements can be met.
Description
Technical field
The present invention relates to a kind of shaping cant mechanism, belong to injection mold technical field.
Background technology
Some products can be often run in injecting products, inner surface sidewall has localized indentation tongue or segmented thread etc., because its stripper distance is from general all shorter, mould and manufacturing cost can be greatly increased as loosed core with Angle Pin, therefore, need one to reduce costs and manufacture simple mechanism to solve the problems referred to above.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose that a kind of structure is simple, the shaping cant mechanism of reliable in action.
Technical solution of the present invention is achieved in that a kind of shaping cant mechanism, comprises mould, plastic, cavity plate, core plate, slanted pushing rod, gripper shoe; Described plastic is arranged in the die cavity of mould; Described cavity plate is arranged on mold bottom; Described core plate is arranged on bottom cavity plate; Described slanted pushing rod upper end is arranged in plastic through cavity plate, core plate, and lower end is fixing on the supporting plate.
Preferably, the size of described slanted pushing rod upper end exceeds cavity lateral 5-6 ㎜.
Preferably, vertical or inclined-plane are arranged in described slanted pushing rod upper end, match with plastic.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The shaping cant mechanism of one of the present invention, by the setting of slanted pushing rod, realizes mould when die sinking, is ejected by plastic in mould, and be convenient in demoulding quick, structure is simple, can improve the modest ability precision of plastic simultaneously and meet shape requirement.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of a kind of shaping cant mechanism of the present invention;
Wherein: 1, mould; 2, plastic; 3, cavity plate; 4, core plate; 5, slanted pushing rod; 6, gripper shoe; 7, die cavity.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
Accompanying drawing 1 is the shaping cant mechanism of one of the present invention, comprises mould 1, plastic 2, cavity plate 3, core plate 4, slanted pushing rod 5, gripper shoe 6; Described plastic 2 is arranged in the die cavity 7 of mould 1; Described cavity plate 3 is arranged on bottom mould 1; Described core plate 4 is arranged on bottom cavity plate 3; Described slanted pushing rod 5 upper end is arranged in plastic 2 through cavity plate 3, core plate 4, and lower end is fixed in gripper shoe 6; The size of described slanted pushing rod 5 upper end exceeds die cavity 7 sidewall 5-6 ㎜; Vertical or inclined-plane are arranged in described slanted pushing rod 5 upper end, match with plastic 2.
Mould 1 is when opening, plastic 2 ejects by slanted pushing rod 5 under ejection system effect, in ejection process, slanted pushing rod 5 end face does transverse movement along plastic 2 inner surface, meanwhile, slanted pushing rod 5 also deviates from the concavo-convex place of sidewall gradually, finally completes stripping action and is deviate from by plastic 2, complete side and twitch work, and then product Automatic-falling can be completed with secondary ejecting mechanism.
When plastic 2 is highly less, namely slanted pushing rod 5 deviate from completely side recessed before, plastic 2 departed from die cavity 7 and without other any supports time, the size of slanted pushing rod 5 upper end exceeds die cavity 7 sidewall 5-6 ㎜, and vertical or inclined-plane is arranged in slanted pushing rod 5 upper end, match with plastic 2, like this when matched moulds, cavity plate 3 can force slanted pushing rod 5 to return original position, and core plate 4 then plays the effect of locking, thus ensure that the smooth motion of slanted pushing rod 5, also improve dimensional accuracy and the shape requirement of plastic 2.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (3)
1. a shaping cant mechanism, is characterized in that: comprise mould, plastic, cavity plate, core plate, slanted pushing rod, gripper shoe; Described plastic is arranged in the die cavity of mould; Described cavity plate is arranged on mold bottom; Described core plate is arranged on bottom cavity plate; Described slanted pushing rod upper end is arranged in plastic through cavity plate, core plate, and lower end is fixing on the supporting plate.
2. a kind of shaping cant mechanism as claimed in claim 1, is characterized in that: the size of described slanted pushing rod upper end exceeds cavity lateral 5-6 ㎜.
3. a kind of shaping cant mechanism as claimed in claim 1, is characterized in that: vertical or inclined-plane are arranged in described slanted pushing rod upper end, match with plastic.
