Abstract
The invention provides a die sleeve. A body of the die sleeve is set as a step-like barrel, and the step shape can disperse stress so as to guarantee the rigidity of the body; meanwhile, an outer stainless steel ring and an inner tetrafluoroethylene ring are arranged at an end opening of an open die, and the surface smoothness of a pipe is greatly improved due to good lubrication and friction reduction performance of the outer stainless steel ring and the inner tetrafluoroethylene ring under the high-load condition; an annular water groove is formed between the outer stainless steel ring and the inner tetrafluoroethylene ring to cool the outer stainless steel ring, and accordingly, the service life is prolonged; the open die is made of a titanium alloy material and is resistant to friction and compression; the lower part of the end opening of the open die is a transition part, and the diameter of the transition part is larger than that of the end opening of the open die, thus the pressure inside the body is dispersed, and the body is prevented from being broken.
Description
Technical field
The present invention relates to a kind of die sleeve.
Background technology
Die sleeve is the mould structure parts for banding master mold or male model.In prior art, die sleeve is to expect one of part common in mould in the first day of the lunar month, although it is widely used in plastic pattern, but still there is some shortcomings part, such as design unreasonable, physical life is short, it has not been convenient to the problems such as installation and removal still also exist in most plastic pattern.
Summary of the invention
For solving above-mentioned technical problem, the invention provides a kind of die sleeve, its objective is to provide a kind of easy accessibility and the die sleeve of long service life.
A kind of die sleeve, it includes body, described body is stepped cylinder, described body upper end is mouth die port, the bottom of described mouth die port is transition part, and the diameter of described transition part is more than the diameter of mouth die port, and the bottom of described transition part is provided with socket part, described mouth die port is provided with rustless steel outer ring and tetrafluoroethene inner ring, is provided with ring dress tank between described rustless steel outer ring and tetrafluoroethene inner ring.
Preferably, described mouth die port includes the opening mould of annular, and described opening mould is made up of titanium alloy material, and described rustless steel outer ring is fixed on opening mould by screw.
Preferably, it is provided with sealing ring between described rustless steel outer ring and tetrafluoroethene inner ring.
A kind of die sleeve provided by the invention, it has the beneficial effects that: die sleeve body is set to stepped cylinder, and stairstepping can ensure the rigidity of body by dispersive stress；Rustless steel outer ring and tetrafluoroethene inner ring are set at mouth die port simultaneously, utilize the lubrication Wear vesistance that it is good when top load, be greatly improved tube surfaces smoothness；It is provided with ring dress tank between rustless steel outer ring and tetrafluoroethene inner ring rustless steel outer ring carries out cooling to carry out cooling and increase the service life；Opening mould is made up wear-resisting pressure of titanium alloy material；Mouth die port bottom is the transition part diameter diameter more than mouth die port, the pressure of dispersion body interior, it is prevented that body ruptures.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below.
Accompanying drawing 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
The present embodiment as it is shown in figure 1,
A kind of die sleeve, it includes body 1, described body 1 is stepped cylinder, described body 1 upper end is mouth die port 2, the bottom of described mouth die port 2 is transition part 3, the diameter of described transition part 3 is more than the diameter of mouth die port 2, the bottom of described transition part 3 is provided with socket part 4, described mouth die port 2 is provided with rustless steel outer ring 5 and tetrafluoroethene inner ring 9, ring dress tank 6 it is provided with between described rustless steel outer ring 5 and tetrafluoroethene inner ring 9, described mouth die port 2 includes the opening mould 7 of annular, described opening mould 7 is made up of titanium alloy material, described rustless steel outer ring 5 is fixed on opening mould 7 by screw, it is provided with sealing ring 8 between described rustless steel outer ring 5 and tetrafluoroethene inner ring 4.
A kind of die sleeve provided by the invention, is set to stepped cylinder by die sleeve body, and stairstepping can ensure the rigidity of body by dispersive stress；Rustless steel outer ring and tetrafluoroethene inner ring are set at mouth die port simultaneously, utilize the lubrication Wear vesistance that it is good when top load, be greatly improved tube surfaces smoothness；It is provided with ring dress tank between rustless steel outer ring and tetrafluoroethene inner ring rustless steel outer ring carries out cooling to carry out cooling and increase the service life；Opening mould is made up wear-resisting pressure of titanium alloy material；Mouth die port bottom is the transition part diameter diameter more than mouth die port, the pressure of dispersion body interior, it is prevented that body ruptures.
The described above of disclosed embodiment of this invention, makes professional and technical personnel in the field be capable of or uses the present invention.The multiple amendment of these embodiments be will be apparent from for those skilled in the art, and generic principles defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention is not intended to be limited to the embodiments shown herein, and is to fit to the widest scope consistent with principles disclosed herein and features of novelty.
