Abstract
The utility model provides a locating pin for a mold. The locating pin for the mold is composed of a main component and an inserting component. The main component is of a circular boss structure, the inserting component is fixed to the middle of the upper surface of the main component, the section, making contact with the main component, of the lower portion of the inserting component is of a cylindrical structure, and the upper portion of the inserting component is of a triangular prismatic structure. The locating pin for the mold is simple in structure and ingenious in design; due to the special structure design of the main component and the inserting component, the fixing effect of a male mold and a female mold is remarkable, a gap and relative displacement which are formed in the machining process of the male mold and the female mold are effectively reduced, and the locating pin for the mold is particularly suitable for application in a sand box mold plate and satisfies the requirement for large-scale industrial production.
Description
Technical field
The utility model relates to mould manufacturing field, especially a kind of dowel for die.
Background technique
Locating stud is in the mould consisting of two-part or more parts, the adjacent two-part of mould are accurately located and the pin of design, visible, locating stud plays the role of positioning, mould must just can be made perfect product by accurate synchronization when closure, and locating stud can allow upper and lower two molds play the effect of accurate location.
In Design of Dies and manufacture, locating stud is one of modal part, and because it is only for the location between part, therefore, few people can give it and too much pay close attention to.
In Cold Press Working, the dimensional accuracy of blanking part depends on the size of punch-die working portion, and the dimension difference between them forms blanking die gap.Gap is the important technical parameter of Stamping Die Design, and its size has a great impact tools such as blanking part cross section quality, blanking force, die lifes.Excessive gap, stamping-out there will be punching burr; Gap is too small, and section can produce secondary slight crack, occurs extruding burr, all make the cross section quality after stamping-out undesirable, and reasonable clearance not only contributes to the raising of stamping-out cross section quality, also contributes to the raising of die life.
In manufacturing process, according to the different gap assured plan adopting in Design of Dies, correspondingly take different gap equipment adjustment methods, at present, normal use have equipment adjustment methods such as pad method, light transmission method, method of measurement, copper facing (zinc) method, coating, technique allowance, positioning work piece location.
In general, the working part that punch, die are processed respectively, because the reasonable clearance of mould in theory forms, therefore, its assembling principle is to fix the working part of be difficult for adjusting, and guarantees that by adjusting the position that the position of another working part changes between punch-die gap is even, now, only pull tight in advance screw, not fixed locating stud.
Yet practical experience is for many years noticed those skilled in the art, if can pay close attention to targetedly locating stud, use locating stud, often can produce the special effect of getting twice the result with half the effort in Design of Dies or manufacture process.Therefore, for particular mold, design targetedly locating stud, there is very important production practices meaning.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of dowel for die.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of dowel for die, by main body part and insertion parts, formed, described main body part is round boss structure, described insertion parts is fixed on described main body part upper surface middle part, this insertion parts bottom and main body part contact-segment are cylindrical-shaped structure, and this insertion parts top is triangular prism shape structure.
Preferably, above-mentioned dowel for die, the arranged outside of described main body part and insertion parts has anticorrosive coat.
Preferably, above-mentioned dowel for die, described anticorrosive coat is polypropylene layer.
Preferably, above-mentioned dowel for die, the material of described main body part and insertion parts is chromium-austenitic stainless steel 304 materials.
The utility model structure has following beneficial effect:
Above-mentioned dowel for die, simple in structure, design ingenious, the special construction design of main body part and insertion parts, outstanding to the fixed effect between punch, die, effectively reduce the gap and the relative displacement that between punch, die, in course of working, form, be particularly adapted at applying in sandbox template, be applicable to the needs of large-scale industrial production.
Accompanying drawing explanation
Fig. 1 is the structural representation of dowel for die described in the utility model.
In figure: 1-main body part 2-insertion parts
2-1-cylindrical-shaped structure 2-2-triangular prism shape structure
Embodiment
For further illustrating the utility model, now coordinate accompanying drawing to be described in detail:
As shown in Figure 1, described dowel for die, by the main body part 1 of chromium-austenitic stainless steel 304 materials and the insertion parts 2 of chromium-austenitic stainless steel 304 materials, formed, described main body part 1 is round boss structure, described insertion parts 2 is fixed on described main body part 1 upper surface middle part, these insertion parts 2 bottoms and main body part 1 contact-segment are cylindrical-shaped structure 2-1, these insertion parts 2 tops are triangular prism shape structure 2-2, outside in described main body part 1 and insertion parts 2 is also provided with anticorrosive coat, and described anticorrosive coat is polypropylene layer.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
