Abstract
The utility model discloses a machining mould special for a hexagonal socket head cap screw. The machining mould special for the hexagonal socket head cap screw comprises a male mould, a female mould casing pipe, a sheet mould, an inner mould, a locking screw and a push pin, wherein the inside of the sheet mould is provided with a through hole, the through hole is composed of a cylindrical hole and a circular-truncated-cone hole which are coaxially arranged, and the bore diameter of the connecting end between the circular-truncated-cone hole and the cylindrical hole is larger than the bore diameter of the other end of the circular-truncated-cone hole. Due to the facts that the through hole of the sheet mould is arranged as two parts, a headform is more plump after a secondary-procedure semi-finished product is formed through the coaxially arranged cylindrical hole and the circular-truncated-cone hole, so that the headform of a subsequent third-procedure semi-finished product is guaranteed to be plump, and quality and beauty of products are both greatly improved.
Description
Technical field
The utility model relates to an a kind of cup hexagon socket head cap screw dedicated processing mould.
Background technology
Like Fig. 1-4 is in the moulding process of a cup hexagon socket head cap screw, and at the semi-finished product sketch map that different operations obtain, it is followed successively by blank 11, preface semi-finished product 12, two preface semi-finished product 13 and three preface semi-finished product 14 from top to bottom.Wherein, in second operation, two preface semi-finished product, 13 head dummys that obtain are full inadequately; The flower tooth is clear inadequately; Reason is that the internal structure of sheet mould 31 in former second operation is a chamfering, and is as shown in Figure 6, and if the head dummy of two preface semi-finished product 13 not full; Then cause the head dummy of three preface semi-finished product 14 not full, finally influence product quality.
The utility model content
For solving the problems of the technologies described above, the utility model provides an a kind of cup hexagon socket head cap screw dedicated processing mould, and is full to guarantee the half-finished head dummy of two prefaces, guarantees product quality.
For achieving the above object, the technical scheme of the utility model is following:
An a kind of cup hexagon socket head cap screw dedicated processing mould; Comprise male model, master mold sleeve pipe, sheet mould, internal mold, lock screw and the distribution of effect successively; The inside of said mould has through hole; Said through hole is made up of coaxial cylindrical hole of offering and round platform hole, and the aperture of said round platform hole and cylindrical hole link is greater than the aperture of the said round platform hole other end.
Pass through technique scheme; The cup hexagon socket head cap screw dedicated processing mould that the utility model provides; Its through hole through the sheet mould is set to two parts; Head dummy is fuller after realizing two preface semi-finished product moulding through coaxial cylindrical hole of offering and round platform hole, and full to guarantee three follow-up preface semi-finished product head dummys, product quality and aesthetic property all are greatly improved.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below.
Fig. 1-4 is the semi-finished product structural representation that the different operations of a cup hexagon socket head cap screw moulding process obtain;
Fig. 5 is the decomposition texture sketch map of the utility model;
Fig. 6 is the cross-sectional schematic of sheet mould in the prior art;
Fig. 7 is the cross-sectional schematic of disclosed mould of embodiment.
Numeral among the figure:
11. blank 12. 1 preface semi-finished product 13. 2 preface semi-finished product
14. three preface semi-finished product, 21. male models, 22. master mold sleeve pipes
23. sheet mould 24. internal molds 25. lock screws
26. promote 31. moulds
The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment will be carried out clear, intactly description.
According to Fig. 5 and Fig. 7; The cup hexagon socket head cap screw dedicated processing mould that the utility model provides; Comprise male model 21, master mold sleeve pipe 22, sheet mould 23, internal mold 24, the lock screw 25 of effect successively and promote 26; The inside of sheet mould 23 has through hole, and through hole is made up of coaxial cylindrical hole of offering and round platform hole, and the aperture of round platform hole and cylindrical hole link is greater than the aperture of the round platform hole other end.
The cup hexagon socket head cap screw dedicated processing mould that the utility model provides; Its through hole through sheet mould 23 is set to two parts; Head dummy is fuller after realizing 13 moulding of two preface semi-finished product through coaxial cylindrical hole of offering and round platform hole; Full to guarantee follow-up three preface semi-finished product, 14 head dummys, product quality and aesthetic property all are greatly improved.
Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
