Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in the present invention and the feature in embodiment can be mutually combined.
Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
The present invention relates to a kind of blowning installation, it is be applicable to being had the product of cavity by the extrusion die extrusion with annular die, its overall structure mainly includes feeder, supply air line and supplying terminal, feeder is mainly for generation of gas, and push this gas to supply air line, supply air line connection is arranged between feeder and supplying terminal, to be delivered to the gas of feeder in the cavity of product.By this structure, during the product of extrusion can be made in entering vulcanizing oven by Hot-blast Heating, the pressure in product cavity keeps consistent with atmospheric pressure, prevents what product from producing because external and internal pressure is inconsistent to subside.
Based on the as above integrally-built thought that arranges, the blowning installation that the present embodiment relates to, as a example by preparing a bar sealing strip, this bar sealing strip has two cavitys, and therefore, corresponding feeder is similarly two.Fig. 1 illustrate only the supplying terminal structure in the overall structure of wherein a set of feeder and another set of feeder.As a example by wherein a set of feeder structure, as shown in Figure 1, feeder uses air pump 1, and air pump 1 is housed in the frock box 2 of inner hollow, in order to realize air pump 1 fixing in frock box 2, air pump 1 is attached on the bottom surface of frock box 2 by mounting bracket 3.It in the cavity of frock box 2, is also fixed with the speed regulator 4 being adjusted that electrically connect, the pump gas speed to air pump 1 with air pump 1, by speed regulator 4, it is possible to achieve be adjusted the pump tolerance of air pump 1.In addition, in order to provide a preferably working environment to air pump 1, on a sidewall of frock box 2, it is provided with air exhausting device 5, air exhausting device 5 can use ventilating fan, by air exhausting device 5, it is possible to achieve the circulation of frock box 2 inner air and outer air, and the temperature in guaranteeing frock box 2 maintains under the optimum working temperature environment of air pump 1.
Supply air line 6 uses flexible pipe in the present embodiment, in order to the setting of pipeline, and its one end is connected on the gas outlet of air pump 1, and the other end is connected with the inlet channel 701 of supplying terminal 7.
In the present embodiment, in order to make overall structure compacter, and improving using effect, supplying terminal 7 is inlaid in annular die 8.By Fig. 2, Fig. 3, shown in Fig. 5, generally one column of annular die 8, with the front end face of state shown in Fig. 2 for free end end face 801, it is also the extruding end of product, with the upper surface open section of state shown in Fig. 3 for feed cavity 802, it is provided with core rod 803 in the inside of the annular die 8 near free end end face 801, the exterior contour of core rod 803 and periphery mould 804 spacing around exterior contour are arranged, to form the die cavity 805 for material extrusion molding, material is entered by feed cavity 802, after die cavity 805, extruded by free end end face 801, to form product, cavity on this product is then because core rod 803 is formed.
In order to realize that supplying terminal 7 is inlaid in annular die 8, as shown in Figure 4, figure shows the position relationship of two supplying terminals in Fig. 1, as a example by one of them supplying terminal 7, in the present embodiment, inlet channel 701 and outlet passageway 702 in supplying terminal 7 be arranged in parallel, therebetween connected by center-aisle 703, each passage all uses hard material to make, and each channel interior is provided with hollow pipeline, to realize the connection between each passage.In conjunction with shown in Fig. 5, two outlet passageways 702 are integrated in the cavity of each self-corresponding product, in order to make overall structure more simplify, in the present embodiment, the gabarit of outlet passageway 702 is arranged to the structure of required core rod 803, while i.e. may be implemented in the delivered inside gas of outlet passageway 702, outlet passageway 702 is made to have the effect of core rod 803.
Inlet channel 702 is vertically inlaid in annular die 8 by the free end end face 801 of annular die 8, being radially arranged of center-aisle 803 annularly mouth die 8, outlet passageway 803 is then arranged on the middle part of annular die, namely forms core rod 803 position of product cavity.
Additionally, as shown in Figure 1, it in order to realize the visualizing monitor to the pressure in product cavity and ambient pressure in the present embodiment, is additionally provided with the pressure-detecting device detecting the gas pressure being delivered in product cavity via supplying terminal 7.The pressure-detecting device of the present embodiment for connecting the U-shaped water manometer 9 arranging with supply air line 6.This U-shaped water manometer 9 is fixedly installed relative to frock box 2 position, it includes the backboard 901 forming immobilizing foundation, the inside being fixed on backboard 901 is filled with the U-tube 903 of water column 902, and one end of U-tube 903 was connected with supply air line 6 by communicating pipe 904, and the other end communicates with air.On backboard 901 between two vertical pipeline sections of U-tube 903, it is fixed with the scale 905 that the height value to the water column 902 in U-tube 903 measures, measurement by water-column value in two vertical pipeline sections to U-tube 903 for the scale 905, can finally obtain difference in height h of water column in two vertical pipeline sections, by the change of difference in height h, the pressure change in product cavity can be obtained, with the speed that controls air pump 1 by regulation speed regulator 4, and the uniformity of the force value in finally guaranteeing product cavity and ambient pressure value.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
