Abstract

The utility model provides a water supply pipe mould which comprises a sub-runner, a core mould and a neck mould; the sub-runner goes out between the core mould and the neck mould; an air flue is arranged at the port of the core mould; and the other end of the air flue is communicated with external air. According to the water supply pipe mould, the air flue is arranged; a siphonula penetrates through a forming sleeve and a spray tank after startup or pipe breakage and is drawn onto a tractor; during the process, due to the air flue, the siphonula is communicated with the external air; when the siphonula enters the forming sleeve, the pressure in the siphonula is higher than that in the external forming sleeve; and the siphonula immediately becomes round after the spray tank sprays water to complete initial formation and quickly extrude the air in the forming sleeve, so that the inside of the forming sleeve is in a vacuum state, the outer wall of the siphonula is tightly attached on the inner wall of the forming sleeve, and the formation is completed. The operation is simple, the production time is greatly reduced, the efficiency is improved, meanwhile no hole needs to be arranged below the siphonula, the production of waste is effectively suppressed, the cost is saved and very high practicality is realized.

Description

A kind of feed pipe mould

Technical field

The utility model relates to a kind of tubing production equipment, particularly a kind of feed pipe mould.

Background technology

In the prior art, the production of feed pipe all is through the pipe mold extrusion molding.The tubing raw material obtains pipe through the feed pipe mould, through typing cover and spraying box typing, obtains feed pipe through hauling machine and cutting machine then.At present, feed pipe mould 100 ' commonly used is as shown in Figure 1 usually, comprises runner 101 ', core 102 ' and a mouthful mould 103 '; The tubing raw material passes runner 101 ' acquisition pipe between core 102 ' and mouthful mould 103 '; Through manual work or traction tube pipe is passed typing cover and spraying box then, lead on the hauling machine, in this process, the pipe end is screwed in together; Otherwise can't pass typing cover, so just to have begun be flat to pipe.Because the pipe port is screwed in together, air is plugged and can't gets into pipe, and the pipe inner air is along with the traction of pipe is more and more thinner; Air pressure is very low, and typing cover and spraying box cause air to get into owing to can't effectively seal; Can't keep vacuum state; So typing cover internal gas pressure is greater than the pipe internal gas pressure, pipe is flat always under gas pressure, is difficult to become the circle typing.Therefore, the method that is employed in mouthful mould trickle and perforate under pipe makes the pipe air pressure inside greater than outside typing cover air pressure, thereby makes pipe become the circle typing.Yet, make in this way, must wait the pipe section of perforate to pass spraying box after, spraying box just begins trickle, not so can influence the tubing internal soundness, the wave striped occurs.So use this die production, lead pipe again behind start or the disconnected pipe, troublesome poeration, inefficiency is easy to generate waste product simultaneously, increases manufacturing cost.

Summary of the invention

In order to overcome the deficiency of prior art, the utility model provides a kind of can accomplish the pipe typing very soon, simple to operate, raises the efficiency, and effectively suppresses waste product simultaneously and produces, and practices thrift the feed pipe mould of cost.

The utility model solves the technical scheme that its technical problem adopted: a kind of feed pipe mould; Comprise runner, core and mouthful mould; Said runner is by passing between said core and said mouthful of mould, and said core port offers air flue, and the said air flue other end communicates with extraneous air.

The utility model offers air flue, behind start or disconnected pipe, again pipe is passed typing cover and spraying box, leads on the hauling machine, in this process; Because the existence of air flue, pipe communicates with extraneous air, and when pipe got into the typing cover, the pipe air pressure inside was greater than outside typing cover internal gas pressure; Behind the spraying box trickle, can become round immediately, accomplish tentatively typing, and air is extruded in the cover of will finalizing the design very soon; Make in the typing cover to be in vacuum state, the pipe outer wall is close to typing cover inwall, accomplishes typing.Simple to operate, shorten the production time greatly, raise the efficiency, do not need perforate under pipe simultaneously, effectively suppress waste product and produce, practice thrift cost, have very strong practicality.

In one embodiment, said runner interlude is provided with the shunting support, and the said air flue other end is passed by the shunting support.Said shunting support has supporting role, is convenient to offer air flue simultaneously, and the air flue other end is passed by the shunting support, makes the length of air flue be unlikely to oversize, guarantees circulation of air.

The beneficial effect of the utility model is: the utility model offers air flue, behind start or disconnected pipe, again pipe is passed typing cover and spraying box, leads on the hauling machine; In this process, because the existence of air flue, pipe communicates with extraneous air; When pipe got into the typing cover, the pipe air pressure inside can become round greater than outside typing cover internal gas pressure immediately behind the spraying box trickle; Accomplish preliminary typing, and air is extruded in the cover of will finalizing the design very soon, made in the typing cover to be in vacuum state; The pipe outer wall is close to typing cover inwall, accomplishes typing.Simple to operate, shorten the production time greatly, raise the efficiency, do not need perforate under pipe simultaneously, effectively suppress waste product and produce, practice thrift cost, have very strong practicality.

Fig. 1 is the structural representation of feed pipe mould in the prior art.

Fig. 2 is the structural representation of an embodiment of the utility model.

Omitted among the figure and the irrelevant miscellaneous part of the utility model key points in design.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment, the utility model is explained further details.

As shown in Figure 2; A kind of feed pipe mould 100 of the utility model; Comprise runner 101, core 102 and mouthful mould 103; Said runner 101 is by passing between said core 102 and said mouthful of mould 103, and said core 102 ports offer air flue 104, and said air flue 104 other ends communicate with extraneous air.The utility model connects the typing cover in core 102 ports, typing puts is equipped with spraying box, and spraying box is provided with shower, is used to drench cooling water and makes the pipe typing.(typing cover, spraying box, shower do not belong to this mould part, so not shown)

The tubing raw material passes runner 101 acquisition pipes between core 102 and mouthful mould 103, behind start or disconnected pipe, again pipe is passed typing and overlaps and spraying box, leads on the hauling machine; In this process, because the existence of air flue 104, pipe communicates with extraneous air; When pipe got into the typing cover, the pipe air pressure inside can become round greater than outside typing cover internal gas pressure immediately behind the spraying box trickle; Accomplish preliminary typing, and air is extruded in the cover of will finalizing the design very soon, made in the typing cover to be in vacuum state; The pipe outer wall is close to typing cover inwall, accomplishes typing.Simple to operate, shorten the production time greatly, raise the efficiency, do not need perforate under pipe simultaneously, effectively suppress waste product and produce, practice thrift cost, have very strong practicality.

In the present embodiment, said runner 101 interludes are provided with shunting support 105, and said air flue 104 other ends are passed by shunting support 105.Said shunting support 105 has supporting role, is convenient to offer air flue 104 simultaneously, and air flue 104 other ends are passed by shunting support 105, make the length of air flue 104 be unlikely to oversize, guarantee circulation of air.

More than be merely the preferred embodiment of the utility model, but the design concept of the utility model is not limited thereto, all insubstantial modifications of utilizing this design that the utility model is made also all fall within the protection domain of the utility model.
