Description
Technical field
The utility model relates to technical field of mold, particularly relates to a kind of thin-walled dark type screw post holes anti-sticking die.
Background technology
Screw column is the assembly structure that the maximum a kind of product of application interfixes in automobile and household appliances.In a set of product, have at least the screw column of more than 6 to be used for fixing product, due to requirements such as interiors of products structure and outward appearances, the screw suspension column also corresponding interiors of products that is arranged in respectively, prevents the product of upper and lower covers from use coming off.For the product that product face height is higher, the suspension column height of screw column is also corresponding higher.And the molten plastic of PP, PC, PC+ABS etc. is broken because suspension column very easily appears in suspension column sticking to mould after shaping, surface produces the problems such as shrinkage depression, even there will be the phenomenon that the fuse in the middle of suspension column is pulled off.Directly affect the appearance requirement of product and the delivery ratio of client.
Utility model content
To the present situation of above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of thin-walled preventing product from sticking together when the demoulding dark type screw post holes anti-sticking die.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of thin-walled dark type screw post holes anti-sticking die, comprise moving platen and die pad, this moving platen is placed in above die pad, base plate is provided with below described die pad, described die pad comprises die pad and bottom knockout plate, described base plate is provided with thimble fuse, this thimble fuse one end is placed in base plate, the other end runs through bottom knockout plate successively, upper die pad and moving platen, described thimble fuse overcoat has ejector sleeve, this ejector sleeve is placed in die pad and moving platen, stopping means is provided with between described thimble fuse and base plate, described stopping means comprises spacing hole and position-limiting tube, described spacing hole is placed on base plate, described position-limiting tube is placed on outside thimble fuse.
Further, described thimble fuse lower end is convex character shape, and described position-limiting tube inner surface is provided with the convex shape hole of matching with convex character shape.
Further, described spacing hole upper end is provided with projection.
Further, described position-limiting tube lower end is provided with step, and this stepped diameters is greater than described projection diameter, is less than spacing hole lower end diameter, by arranging projection and step, plays position-limiting action.
Further, be provided with oil cylinder below described base plate, power is provided.
Compared with prior art, the utility model has the advantage of: the utility model, by arranging stopping means, for directly controlling the stroke of thimble fuse and ejector sleeve, thus reaches position-limiting action; By arranging upper die pad and bottom knockout plate, spacing for coordinating stopping means to complete, the utility model is reasonable in design, can large-scale promotion.
Accompanying drawing explanation
Fig. 1 is a kind of thin-walled of the utility model dark type screw post holes anti-sticking die structural representation.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, a kind of thin-walled dark type screw post holes anti-sticking die, comprise moving platen 1 and die pad, this moving platen 1 is placed in above die pad, base plate 2 is provided with below described die pad, described die pad comprises die pad 3 and bottom knockout plate 4, described base plate 2 is provided with thimble fuse 5, this thimble fuse 5 one end is placed in base plate 2, the other end runs through bottom knockout plate 4 successively, upper die pad 3 and moving platen 1, described thimble fuse 5 overcoat has ejector sleeve 6, this ejector sleeve 6 is placed in die pad 3 and moving platen 1, stopping means is provided with between described thimble fuse 5 and base plate 2, described stopping means comprises spacing hole 7 and position-limiting tube 8, described spacing hole is placed on base plate 2, described position-limiting tube 8 is placed on outside thimble fuse 5, described thimble fuse 5 lower end is convex character shape 9, described position-limiting tube 8 inner surface is provided with the convex shape hole 10 of matching with convex character shape 9, described spacing hole 7 upper end is provided with protruding 11, described position-limiting tube 8 lower end is provided with step 12, this step 12 diameter is greater than described protruding 11 diameters, be less than spacing hole 7 lower end diameter, by arranging protruding 11 and step 12, play position-limiting action, oil cylinder 13 is provided with below described base plate 2, power is provided.
Operation principle briefly explains:
During die sinking, die pad drives ejector sleeve 6 and thimble fuse 5 to move, while ejecting product, thimble fuse 5 and product are together ejected 5 ~ 10mm, have behind certain cooling meat gap until the outside of product, after step 12 offsets with protruding 11 simultaneously, thimble fuse 5 cannot move, and ejector sleeve 6 continues motion and ejected by product.Thimble fuse 5 is taken back under the effect of die pad, resets to the end, ensures the position consistency with former thimble fuse 5 and ejector sleeve 6.
Compared with prior art, the utility model has the advantage of: the utility model, by arranging stopping means, for directly controlling the stroke of thimble fuse and ejector sleeve, thus reaches position-limiting action; By arranging upper die pad and bottom knockout plate, spacing for coordinating stopping means to complete, the utility model is reasonable in design, can large-scale promotion.
