Description
Technical field
The utility model relates to pipe fitting core technical field, and more particularly, particularly one is vented ring-like pipe fitting core.
Background technology
Steel skeleton plastic clad pipe part is with punching steel plate for skeleton, the novel pipe fitting of inside and outside wall plastics compound.Pipe fitting is injection mo(u)lding in mould of plastics, and because skeleton is punched-plate, time shaping, melt flows is complicated, die venting difficulty.
For realizing the smooth and easy exhaust of mould, existing mold die cavity adopts split-type structural, respectively on mold parting surface, die cavity combination part, eject position exhaust be set.
Pipe fitting existing mold is when injection mo(u)lding, and skeleton flowing hole size, distribution are different, and stream direction, speed also change thereupon; Skeleton position in the tube, also affects the direction of stream, speed; The change of moulding process, stream direction, speed are also influenced.Along with the change of stream direction, speed, die venting terminal position also changes.Actual mould exhaust position, usually not in the ideal situation discharge end position (the gap exhaust at mold cavity component place).In such mould, gas cannot smooth and easyly be discharged, and this position can produce the defects such as inside and outside wall segmentation crack.Therefore, the pipe fitting core designing a kind of new structure is necessary.
Utility model content
The purpose of this utility model is to provide a kind of exhaust ring-like pipe fitting core, and this pipe fitting core can make the smooth and easy discharge of gas, avoids the problem producing the defects such as inside and outside wall segmentation crack.
In order to solve problem set forth above, the technical solution adopted in the utility model is: the ring-like pipe fitting core of a kind of exhaust, comprise pipe fitting mold core body, it also comprises along axial at least two annular grooves successively of pipe fitting mold core body, be located at the perforate be communicated with bottom each annular groove and with the die cavity of pipe fitting mold core body, be installed on the air exhaust loop on each annular groove, on described air exhaust loop gap be provided with multiple air discharge duct, the axis along described pipe fitting mold core body is also provided with the steam vent be communicated with air discharge duct.
According to a preferred embodiment of the present utility model: each air exhaust loop is fixed in annular groove by marking closely bolt, described in mark closely bolt installing hole in be provided with soft copper shutoff.
According to a preferred embodiment of the present utility model: described annular groove is four groups, and these four groups of annular grooves set gradually along the axis of pipe fitting mold core body.
According to a preferred embodiment of the present utility model: the gap between described two adjacent air discharge ducts is 0.025 ~ 0.04mm.
According to a preferred embodiment of the present utility model: the width of described annular groove is 5mm.
Compared with prior art, the beneficial effects of the utility model are: the utility model, by arranging the structures such as annular groove, air exhaust loop, air discharge duct and steam vent, can make the smooth and easy discharge of the gas in pipe fitting core, avoid the problem producing the defects such as inside and outside wall segmentation crack.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the ring-like pipe fitting core of exhaust of the present utility model.
Fig. 2 is the enlarged drawing at A place in the utility model Fig. 1.
Fig. 3 is the enlarged drawing at B place in the utility model Fig. 1.
Description of reference numerals: 1, pipe fitting mold core body, 2, annular groove, 3, air exhaust loop, 4, steam vent, 5, air discharge duct, 6, mark closely bolt, 7, soft copper shutoff.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult shown in Fig. 1 to Fig. 3, the one that the utility model provides is vented ring-like pipe fitting core, comprise pipe fitting mold core body 1, along axial at least two annular grooves 2 successively of pipe fitting mold core body 1, be located at the perforate be communicated with bottom each annular groove 2 and with the die cavity of pipe fitting mold core body 1, be installed on the air exhaust loop 3 on each annular groove 2, on described air exhaust loop 3 gap be provided with multiple air discharge duct 5, the axis along described pipe fitting mold core body 1 is also provided with the steam vent 4 be communicated with air discharge duct 5.
Each air exhaust loop 3 in the utility model is fixed in annular groove 2 by marking closely bolt 6, described in mark closely bolt 6 installing hole in be provided with soft copper shutoff 7.
Annular groove 2 in the utility model is four groups, and these four groups of annular grooves 2 set gradually along the axis of pipe fitting mold core body 1.
The procedure of processing being vented ring-like pipe fitting core in the utility model concrete is:
The first step, core are transformed: the annular groove 2 of the wide 5mm in turning four road successively vertically in pipe fitting mold core body 1.In the bottom opening of annular groove 2, for gas is drawn core.
Second step, air exhaust loop are processed: by annular groove 2 size of core, process four pairs of air exhaust loops 3.The often pair of air exhaust loop 3 can just the annular groove 2 of complete covering core, is tight fit between the two.On air exhaust loop 3, interval processing air discharge duct 5, the gap of two adjacent air discharge ducts 5 is 0.025 ~ 0.04mm; And be axially arranged with steam vent 4 in pipe fitting mold core body 1.
3rd step, assembling: be arranged on the annular groove 2 of core by air exhaust loop 3 with marking closely bolt 6, the installing hole soft copper plug marking closely bolt 6 is full, then the part higher than core plan is polished.
Above-described embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
