Abstract
The invention provides a locating pin for a mold, which consists of a main part and an insertion part, wherein the main part is of a circular boss structure, the insertion part is fixed in the middle of the upper surface of the main part, the lower portion of the insertion part and the contacting segment of the main part are of a cylindrical structure, and the upper portion of the insertion part is of a triangular prism structure; for the locating pin for the mold, the structure is simple, the design is ingenious, the special structure design of the main part and the insertion part has a prominent fixation effect between a male die and a female die, a gap and a relative displacement formed between the male die and the female die in the machining process are decreased effectively, and the locating pin for the mold is especially suitable for being applied in a sand box template, and is suitable for the need for large-scale industrial production.
Description
Technical field
The present invention relates to mould manufacturing field, especially a kind of dowel for die.
Background technique
Locating stud is in the mould be made up of two-part or more part, the adjacent two-part of mould are accurately located and the pin designed, visible, locating stud plays the role of positioning, mould just must can make perfect product by accurate synchronization when closed, and locating stud can allow upper and lower two molds play the effect of accurately location.
In Mould design and manufacturing, 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 namely 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 adopted in Design of Dies, correspondingly take different gap equipment adjustment methods, at present, normal utilization has the equipment adjustment method such as pad method, light transmission method, method of measurement, copper facing (zinc) method, coating, technique allowance, positioning work piece location.
In general, to the working part that punch, die are processed respectively, because the reasonable clearance of mould in theory is formed, therefore, its assembling principle fixes the working part not easily adjusted, and ensure gap uniformity by the position changed between punch-die, the position adjusting another working part, now, only pull tight screw in advance, not fixed locating stud.
But practical experience for many years makes those skilled in the art notice, if in Design of Dies or manufacture process, locating stud can be paid close attention to targetedly, uses locating stud, often can produce the special effect of getting twice the result with half the effort.Therefore, design locating stud targetedly for particular mold, there is very important production practices meaning.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of dowel for die.
For solving the problems of the technologies described above, technological scheme of the present invention is:
A kind of dowel for die, be made up of main body part and insertion parts, 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 material.
Structure of the present invention has following beneficial effect:
Above-mentioned dowel for die, structure is simple, design ingenious, the special construction design of main body part and insertion parts, fixed effect between punch, die is given prominence to, effectively reduce the gap and relative displacement that are formed in course of working between punch, die, 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 of the present invention.
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 present invention, accompanying drawing is now coordinated to be described in detail:
As shown in Figure 1, described dowel for die, be made up of the main body part 1 of chromium-austenitic stainless steel 304 material and the insertion parts 2 of chromium-austenitic stainless steel 304 material, 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, this insertion parts 2 bottom and main body part 1 contact-segment are cylindrical-shaped structure 2-1, this insertion parts 2 top is triangular prism shape structure 2-2, also be provided with anticorrosive coat in the outside of described main body part 1 and insertion parts 2, described anticorrosive coat is polypropylene layer.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
