Abstract
The utility model belongs to the technical field of pipe demoulding, and particularly relates to an improved mould for demoulding a PE pipe; the improved mould comprises a core die; the head of the core die comprises a first cylinder structure with a smaller diameter, and a second cylinder structure which is connected with a first cylinder and has a larger diameter; and a circle of cushion cover is sheathed on the surface along the circumferential direction of the first cylinder structure. According to the mould, when the pipe is demoulded, a gap between the pipe and the cushion cover is very small since the pipe is expanded when being heated when the pipe passes through the cushion cover, so that the inner wall of the pipe is contacted with the surface of the cushion cover, the inner wall of the demoulded pipe is very smooth after being scraped and worn by cushion cover, and the demoulding quality of the pipe is greatly improved.
Description
Technical field
The new novel tubing ejection technique field of belonging to of this practicality is specifically related to a kind of improved PE pipe tubing demoulding mould.
Background technology
At present, in the tubing releasing process, owing to having certain interval between pipe material inner wall and core, cause after the demoulding smoothness of inner wall of tubing not high, more coarse, affect tubing demoulding quality.and general demoulding mould, especially to leave the gap between core and pipe material inner wall be necessary to PE pipe tubing demoulding mould, the one, in order to adjust the thickness of tubing, the 2nd, for tubing demoulding expanded by heating headspace (after the space of reservation is enough to make the tubing expanded by heating, pipe material inner wall can not contact with the core inner surface yet), prevent the tubing distortion, after the demoulding, pipe material inner wall is coarse just inevitable like this, existing this defective of tubing demoulding mould ubiquity, and whole core outer surface and pipe material inner wall gap are dwindled or gapless, can not satisfy the demand that tubing thickness is regulated, if and tubing directly contacts core (because core is that iron material is made), to very easily make the tubing distortion during demoulding.
The utility model content
After the tubing demoulding in above-mentioned prior art, inner wall coarse, the ropy defective of the demoulding, the utility model provides a kind of improved tubing demoulding mould.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of improved tubing demoulding mould, comprise core,: the core head comprises the second cylindrical structure that the first less cylindrical structure of diameter is larger with the diameter that is connected with the first cylinder, is arranged with a circle cushion cover in the peripheral surface of described the first cylindrical structure.
The ring-type body of cushion cover described in the utility model for adopting the polytetrafluoro material to make, because the polytetrafluoro material has resistance to elevated temperatures preferably, therefore be used for demoulding mould, not be out of shape by temperatures involved, and polytetrafluoro material friction coefficient is extremely low, is difficult for sticking together with tube wall.
The thickness of described cushion cover is not more than the difference of the first cylindrical structure and the second cylindrical structure radius.Design is during for the demoulding like this, (said gap is far smaller than when cushion cover is set here to make cushion cover peripheral surface and pipe material inner wall have certain interval, gap between the first cylinder peripheral surface and pipe material inner wall), to give tubing expanded by heating headspace.
the beneficial effects of the utility model: at first, for satisfy core whole most of want and tubing between be reserved with the gap, so that tubing thickness is adjustable during the demoulding, expanded by heating has enough spaces, the utility model is intended to improve the core head: the core head design becomes to have larger-diameter the second column structure that has that the first column structure of small diameter is connected with this first column structure, and at the sheathed circle cushion cover of the first column structure peripheral surface, in the tubing knockout course, during this cushion cover of tubing process, due to expanded by heating, gap between tubing and cushion cover is very little again, therefore pipe material inner wall will with the cushion cover Surface Contact, through cushion cover surface scraped finish, pipe material inner wall after the demoulding is very smooth, greatly improved the demoulding quality of tubing.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, improve because the utility model is intended to the core head, so the present embodiment only shows the schematic diagram of core head.the improved tubing demoulding mould of the present embodiment, comprise core, core has core head 1, core head 1 comprises the second cylindrical structure 5 that the first less cylindrical structure 4 of diameter is larger with the diameter that is connected with the first cylinder, peripheral surface at described the first cylindrical structure 4 is arranged with a circle cushion cover 2, the ring-type body of described cushion cover 2 for adopting the polytetrafluoro material to make, the thickness of described cushion cover 2 is not more than the first cylinder and the second cylindrical radius difference, be that cushion cover 2 is when being sheathed on the first cylindrical structure, the thickness of cushion cover 2 and the first cylinder radius value sum equal or are slightly less than the radius value of the second cylindrical structure.The present embodiment as shown in the figure, the situation that preferred the second is slightly less than, therefore plant between design cushion cover surface and pipe material inner wall and reserved some gaps, the space is provided for the tubing expanded by heating, stripping result is better, even certain preset clearance not also can reach pipe material inner wall effect Paint Gloss after the utility model demoulding.Described the first cylindrical structure 4 of the present embodiment and the second cylindrical structure 5 are by being screwed into being bolted to together in screwed hole 3.
Demoulding mould after the utility model improves, in the tubing knockout course, when tubing passes through the cushion cover of this core head setting, due to expanded by heating, gap between tubing and cushion cover is very little again, thus pipe material inner wall will with the cushion cover Surface Contact, through the scraped finish of cushion cover surface, pipe material inner wall after the demoulding is very smooth, has greatly improved the demoulding quality of tubing.
Above-described is only preferred embodiment of the present utility model, should be understood that for a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement, these can not affect effect and practical applicability that the utility model is implemented.
