Abstract
The utility model proposes a kind of air plug of rotational-moulding mold, comprise hollow tube and be located at the Access Division of hollow tube one end, mould inside is stretched in described hollow tube and Access Division one end in opposite directions, described Access Division is connected in mould outside, the described mouth of pipe endcapped that stretches into the hollow tube of mould inside, on the sidewall of the described hollow tube that stretches into mould inside, offer air-vent, described hollow tube is by air-vent and mould is outside is communicated with.The utility model is simple in structure, prevents that pore from stopping up, and the hot-air of being convenient in mould is discharged, and produces safer.
Description
Technical field
The utility model relates to a kind of rotation molding technical field, is specifically related to a kind of air plug of rotational-moulding mold.
Background technology
In rotational molding technique, in resin sintering process, in Plastic Rolling Molds, can produce a large amount of hot gas, this just need to take exhaust decompression measure to mould.At present, the common practice in industry is corresponding die location boring in product shelter, during production, in order to reach exhaust and to guarantee the object that resin powder does not leak outside, generally takes to clog with paper roll, steel wool, asbestos fibre.But tend to cause steam vent to stop up and cause product rejection, if carry out rotational foaming production, in the mould after obstruction, can produce powerful air pressure and may set off an explosion, seriously injuring production safety.Therefore, the shortcoming for fear of existing in prior art, is necessary prior art to make improvements.
Utility model content
The purpose of this utility model is to overcome shortcoming of the prior art with not enough, and a kind of air plug of being convenient to the rotational-moulding mold of the hot-air discharge in mould is provided.
The utility model is to realize by following technical scheme: a kind of air plug of rotational-moulding mold, comprise hollow tube and be located at the Access Division of hollow tube one end, mould inside is stretched in described hollow tube and Access Division one end in opposite directions, described Access Division is connected in mould outside, the described mouth of pipe endcapped that stretches into the hollow tube of mould inside, on the sidewall of the described hollow tube that stretches into mould inside, offer air-vent, described hollow tube is by air-vent and mould is outside is communicated with.
Described air-vent is circumferentially laid in the sidewall of hollow tube.
Described air plug also comprises Access Division is fixed on to the fixed part on mould.
Described Access Division is the clamping platform circumferentially extending along the mouth of pipe.
Described fixed part is be sheathed on the first nut outside clamping platform and air plug is compressed on to the second nut on mould, described the first nut is fixedly mounted on mould, described the first nut has internal thread, and described the second nut has the external screw thread suitable with described the first nut.
Described fixed part is the screw being screwed onto on clamping platform.
The aperture of described air-vent is 3mm～5mm.
The aperture of described hollow tube is 10mm～25mm.
With respect to prior art, air plug of the present utility model is simple in structure, easy and simple to handle, is conducive to the discharge of hot-air in mould, prevents that resin powder from leaking outside simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the air plug of the utility model rotational-moulding mold.
In figure: 1. hollow tube; 2. clamping platform; 3. mould; 4. air-vent; 5. the first nut; 6. the second nut
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of air plug of rotational-moulding mold, comprise hollow tube 1 and be located at the Access Division of hollow tube 1 one end, this hollow tube 1 stretches into mould 3 inside with one end in opposite directions, Access Division, this Access Division is connected in mould 3 outsides, stretch into the mouth of pipe endcapped of the hollow tube 1 of mould 3 inside, stretch on the sidewall of hollow tube 1 of mould 3 inside and offer air-vent 4, hollow tube 1 is communicated with mould 3 outsides by air-vent 4.The aperture of hollow tube 1 is 10mm～25mm, and the concrete size in aperture is set according to mould.This hollow tube 1 is not only conducive to the discharge of gas, can also prevent that resin powder from leaking outside.
Air-vent 4 is circumferentially laid in the sidewall of hollow tube 1.The sidewall of hollow tube 1 is circumferentially laid with 4 air-vents 4.The aperture of air-vent 4 is 3mm～5mm, and the concrete size in aperture is set according to mould.
Air plug also comprises Access Division is fixed on to the fixed part on mould 3.Certainly, as a kind of embodiment, the material of this hollow tube 1 can be selected polytetrafluoroethylene (PTFE), can not attach resin and affect forming quality of products in sintering process.
Access Division is the clamping platform 2 circumferentially extending along the mouth of pipe.This fixed part is be sheathed on the first nut 5 outside clamping platform 2 and air plug is compressed on to the second nut 6 on mould 3, this first nut 5 is fixedly mounted on mould 3, the first nut 5 has internal thread, and this second nut 6 has the external screw thread suitable with the first nut 5.As another kind of embodiment, fixed part can be for being screwed onto the screw on clamping platform 2.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
