Abstract
The utility model relates to a kind of structure being conducive to the punching of female mould forming workpiece, it is characterized in that, by skeleton with add plastic structure and form, described skeleton is fixedly connected with by the method for an injection moulding with the described plastic structure that adds, described in add plastic structure internal diameter be less than the external diameter of punching apparatus punch structure; The described upper limb adding plastic structure aligns with the upper limb of described skeleton; Described skeleton and the described plastic structure that adds are pp material; With glue, epidermis is compound on described skeleton; The hardness of described epidermis is less than the hardness of described skeleton.The utility model is set up by the method for an injection moulding and is added plastic structure around position, hole, and the structure after improvement can make the die-cut epidermis got off form smooth section, and the expense of modified node method is low, easy to operate simultaneously.
Description
Technical field
The utility model relates to die cut structural field, particularly relates to a kind of structure being conducive to the punching of female mould forming workpiece.
Background technology
In the forming process of dermatoglyph, the vacuum tightness that between mold cavity block and epidermis, enclosed cavity is formed is the shaping key parameter of epidermis dermatoglyph, and the hole characteristics such as pilot hole therefore can not be had to exist at epidermis dermatoglyph formative stage, can only be shaping in following process.So the punching molding course of processing can only be carried out to it after dermatoglyph is formed.
Very strict to die-cut clearance requirement in Punching Technology process, almost zero joins and could meet clearance requirement, but in actual production process, after the die-cut use of mould small―gap suture about 500 times, because the reason gap of the wearing and tearing of cutting edge can not meet production requirement again; Punch pin is owing to needing to design according to the shape of product, there is some holes position feature itself narrower and small, undercapacity when making mold insert designs, cause peripheral clearance even not, or in Mould Machining and bedding-in process, the peripheral clearance heterogeneity caused, makes to occur die-cut bad defect in epidermis punch process; Epidermis is subject to punch downward pressure and produces recoverable deformation, and position, epidermis hole leaves burr after tearing, and does not meet product requirement.
Utility model content
For the weak point existed in the problems referred to above, the utility model provides a kind of structure being conducive to the punching of female mould forming workpiece.
For achieving the above object, the utility model provides a kind of structure being conducive to the punching of female mould forming workpiece, it is characterized in that, by skeleton with add plastic structure and form, described skeleton is fixedly connected with by the method for an injection moulding with the described plastic structure that adds, described in add plastic structure internal diameter be less than the external diameter of punching apparatus punch.
The described upper limb adding plastic structure aligns with the upper limb of described skeleton.
Described skeleton and the described plastic structure that adds are pp material.
With glue, epidermis is fixed on described skeleton time die-cut.
The hardness of described epidermis is less than the hardness of described skeleton.
The beneficial effects of the utility model are:
Set up around position, hole by the method for integrated injection molding and add plastic structure, the structure after improvement can make the die-cut epidermis got off form smooth section, and the expense simultaneously improved equipment is low, easy to operate.

Description of reference numerals:
1, plastic structure 2, punch 3, skeleton 4, epidermis is added
Embodiment
As Figure 1-5, a kind of structure being conducive to the punching of female mould forming workpiece described in the utility model embodiment, by skeleton 3 with add plastic structure 1 and form, described skeleton 3 is fixedly connected with by the method for an injection moulding with the described plastic structure 1 that adds, described in add plastic structure 1 internal diameter be less than the external diameter of punching apparatus punch 2.
The described upper limb adding plastic structure 1 aligns with the upper limb of described skeleton 3.
Described skeleton 3 and the described plastic structure 1 that adds are for pp material.
With glue, epidermis is compound on described skeleton 3 time die-cut.
The hardness of described epidermis 4 is less than the hardness of described skeleton 3.
During concrete use: manufacture skeleton by the method for single injection-molded and add the one punch structure of plastic structure, adding the increase of plastic structure, make epidermis enter into three-dimensional compressive stress state very soon from elastic deformation.The structure being conducive to the punching of female mould forming workpiece is put on the die of die cutting device, along with the continuous decline of punch, epidermis generation viscous deformation is at punch cutting edge place and occur crackle, and now skeleton has just started the stressed recoverable deformation that occurs, along with punch continues to decline, now epidermis is under the anchorage force effect of skeleton, ductility is blocked further, can not extend, final with the form of crackle, continuous growth strengthens, the now pressure increase that is subject to of skeleton, there is part viscous deformation, and there is crackle, the hardness relative injection skeleton hardness of epidermis is less, now skeleton crackle sharp corner can be formed and be similar to cutting edge of die, crackle can be there is herein in epidermis, by with punch cutting edge near appearance flaw shape become intersect, make that epidermis is punched to get off, and form bright and clean section.Comparison diagram 4 and Fig. 5 known, the die-cut surface section of the utility model structure is smooth, and burr appear in the section of the surface generated by traditional method, uneven.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
