Abstract
The invention discloses a mold structure. A mold body comprises a through pipeline formed along the axis position. The pipeline comprises an open part, a gradual contraction part and an extending part. The open part is arranged on the surface of the mold body and extends towards one end of the pipe. The diameter of the open part is larger than the outer diameter of a pipe to be mounted. The caliber of the open part is larger than that of the gradual contraction part, and the extending part extends to the tail end of the pipeline from the other end of the gradual contraction part. The outer diameter of the pipe is effectively prevented from abnormally deforming, the product quality is improved, and the service life of a product is prolonged; and the mold structure has the beneficial effects that the improvement cost is low, and cost is reduced.
Description
Technical field
The present invention relates to a kind of mould, particularly relate to a kind of pipe mold.
Background technology
Manufacture body in the industry and mainly utilize drilling machine, lathe or the processing of other devices, the making of body to be solid tubing originally, waste material through process equipment central authorities is removed, pipe body shape is controlled in formation, but, when tubing uses, often in order to particular demands, the internal-and external diameter of compression tubing that must be suitable, when tubing docks, or for the gun barrel etc. of peashooter, existing processing mode, in mould, there is pipeline, the bore of pipeline is less than the external diameter of tubing, therefore, after mould put into by tubing, just the internal diameter of tubing can be made to reduce by compressing, bore due to pipeline is less than the external diameter of tubing, tubing is when putting into pipeline, the mouth of pipe place of tubing is often caused to produce distortion because of shock or pressure, cause Quality Down.
Therefore those skilled in the art are devoted to develop a kind of on-deformable tube opening.
Summary of the invention
Because the above-mentioned defect of prior art, technical problem to be solved by this invention is to provide a kind of on-deformable tube opening.
For achieving the above object, the invention provides a kind of mould structure, die ontology comprises the pipeline of the through shape offered along shaft core position; Described pipeline comprises opening portion, convergent portion and extension;
Described opening portion is arranged on the surface of described die ontology, and described opening portion extends to one end of described pipeline; The diameter of described opening portion is greater than the external diameter of described tubing to be installed; Described extension extends described pipe end by this convergent portion other end, and the bore of described extension is identical with the lowest calibre in described convergent portion; Convergent portion by opening part to by convergent in pipeline.
Conveniently produce and cost-saving, described die ontology is formed in one structure.
The invention has the beneficial effects as follows: the present invention effectively prevents the external diameter of tubing to produce abnormal deformation, improves the quality of product, extends the service life of product, have improvement cost low, cost-saving beneficial effect such as grade.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the sectional structure schematic diagram in the present invention.
Fig. 3 is the using state structural representation in the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples
The invention will be further described:
As shown in Figure 1-Figure 3, a kind of mould structure, die ontology 1 is formed in one structure.Die ontology 1 comprises the pipeline 11 of the through shape offered along shaft core position; Pipeline 11 comprises opening portion 12, convergent portion 13 and extension 14.
Opening portion 12 is arranged on the surface of die ontology 1, and opening portion 12 extends to one end of pipeline 11; The diameter of opening portion 12 is greater than the external diameter of tubing to be installed; The opening portion bore of opening portion 12 is the bore being greater than convergent portion 13, and extension 14 is by this convergent portion 13 other end extensional pipeline 11 end, and the bore of extension 14 is identical with the lowest calibre in convergent portion 13; The least radius in convergent portion 13 is 4cm; Convergent portion 13 by opening part to by convergent in pipeline 11.
Man-hour is added when tubing 2 carries out reduced diameter, one end of this tubing 2 is nested in die ontology 1, now, bore due to the opening portion 12 of die ontology 1 is greater than the external diameter of this tubing 2, then tubing 2 is when being inserted in this mould 1, the position of this mould 1 is inserted in this tubing 2 front end, unnecessary distortion can not be produced because of identical being squeezed of bore, then, because this convergent portion 13 is in level and smooth convergent, therefore, after this tubing 2 is subject to the extruding in this convergent portion 13, the external diameter of tubing 2 will be reduced gradually, because this convergent portion 13 is level and smooth convergent, therefore, this tubing 2 is when reducing, can not amplitude of deformation be caused excessive because of convergent rapidly and produce undesirable deformation, thus ensure that the quality of product, in addition, this tubing 2 convergent aftershaping is compression unit 21, the length of this compression unit 21 is according to needs when using, just extend by upper extension 14, thus the bore of extension 14 equals the lowest calibre in this convergent portion 13, therefore, tubing 2 is continued to be pressed in mould 1, just the length of sustainable increasing compression unit 21.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technical staff in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
