Abstract
The invention discloses a triangular self-tapping screw molding die which comprises an upper die, a lower die, a head cavity and a rod cavity. The head cavity is arranged in the upper die, and the rod cavity that is triangular is arranged in the lower cavity. An upper die kernel is arranged in the upper die and a lower die kernel is arranged in the lower die. The head cavity is located at the bottom of the upper die kernel and the rod cavity is located in the lower die kernel. The upper die kernel and the lower die kernel are made of hard alloy materials. The triangular self-tapping screw molding die provided by the invention is a molding die specially for producing triangular self-tapping screws, the triangular self-tapping screws can be molded integrally, and continuous production can be realized, therefore, not only are the raw materials and working hours are saved, but also the production efficiency is improved, the production cost is reduced greatly, and the production quality is controlled effectively.
Description
Technical field
The present invention relates to a kind of mould, relate in particular to a kind of trigonodont tapping screw mould.
Background technology
The trigonodont tapping screw; Principle development based on the plain screw self tapping forms, and screw thread and the tail end with particular design makes screw can under interrupted pressure, be rolled into the negative thread of cooperation, the space at the bottom of the material around the hole can be filled up common tapping screw screw thread and tooth more easily simultaneously voluntarily; Because the more common tapping screw of its friction is little; Therefore can use on thicker material, rotate required moment of torsion and better control, and combination back intensity is higher.
Along with China's rapid development of economy, to the production technology of standard component with require increasingly highly because the common tapping screw intensity of strength ratio of trigonodont tapping screw is bigger, so nowadays the trigonodont tapping screw has replaced the common tapping screw that is adopted in the past.Because constantly bringing forth new ideas of China's every field technology, along with a large amount of releases of common tapping screw, the method for producing common tapping screw according to routine can not meet the needs of fully.
The common tapping screw in past all comes out through machined into, and such processing mode needs car to fall many clouts; Serious waste raw material, and long processing time, waste process time; Inefficiency, the product quality of producing can not get effective assurance, and belongs to nonstandard part let alone the trigonodont tapping screw; The mode of machined into is difficult to it is processed, and the production technology innovation of trigonodont tapping screw has become the key of producing the trigonodont tapping screw.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: the trigonodont tapping screw mould that has proposed the nonstandard part trigonodont of a kind of special production tapping screw.
Technical solution of the present invention is achieved in that a kind of trigonodont tapping screw mould; Comprise upper die and lower die, head shape chamber and bar portion shape chamber; Said head shape chamber is arranged in the patrix, and said bar portion shape chamber is arranged in the counterdie, and said bar portion shape chamber is triangular in shape.
Preferably, be provided with upper cores in the said patrix, be provided with down die in the counterdie; Said head shape chamber is positioned at the upper cores bottom; Said bar portion shape chamber is positioned at die down; Said upper cores adopts Hardmetal materials to process with following die.
Preferably, also be provided with knock pin in the said counterdie.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Trigonodont tapping screw mould of the present invention; Be a mould of producing the trigonodont tapping screw that is specifically designed to, can the one-shot forming of trigonodont tapping screw can be carried out continuity production; Not only practiced thrift raw material but also practiced thrift man-hour; Improve production efficiency greatly, reduced production cost, effectively controlled the quality of production.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the structural representation of trigonodont tapping screw mould of the present invention;
Accompanying drawing 2 is the shape cavity configuration sketch map of trigonodont tapping screw mould of the present invention;
Structural representation when accompanying drawing 3 is the trigonodont tapping screw moulding of trigonodont tapping screw mould of the present invention;
Wherein: 1, patrix; 2, counterdie; 3, head shape chamber; 4, bar portion shape chamber; 5, upper cores; 6, following die; 7, knock pin; 8, trigonodont tapping screw.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 3 is a kind of trigonodont tapping screw mould of the present invention; Be a mould of producing the trigonodont tapping screw that is specifically designed to, can 8 one-shot formings of trigonodont tapping screw can be carried out continuity production; Not only practiced thrift raw material but also practiced thrift man-hour; Improve production efficiency greatly, reduced production cost, effectively controlled the quality of production.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
