Abstract
The utility model discloses a hot smelting socket welding mould. The hot smelting socket welding mould comprises a hot melting wall of a cylindrical structure and a connecting plate connected to one end of the hot melting wall. The hot melting wall is at least provided with an exhaust passage in the axial direction, and the exhaust passage penetrates through the whole hot melting wall. The sidewall or/and the end face, deviating from the hot melting wall, of the connecting plate is at least provided with an exhaust hole communicated with the exhaust passage. According to the technical scheme, the exhaust passage is additionally formed in the hot smelting socket welding mould, the air in a bell and spigot is exhausted through the exhaust passage, and the problems that in the prior art, air resistance can be easily generated and then hot melting connecting quality is affected in the hot melting process of pipe fittings are solved; the hot smelting socket welding mould is simple in structure, convenient to operate, not prone to generating air resistance, good in hot melting effect of the pipe fittings, high in connecting strength between the pipe fittings, good in sealing performance and applicable to the hot melting socket field.
Description
Technical field
The utility model relates to the thermofusible spigot field of tubing, refers to particularly a kind of thermofusible spigot weld mold.
Background technique
At present, for improving the reliability being connected between pipe fitting and tubing, mostly can joint socket be set in the end of pipe fitting, this joint socket comprises coaxially arranged internal ring wall and external annulus.When thermofusible spigot, first with thermofusible spigot weld mold, internal ring wall outer surface and external annulus internal surface are heated, heat the inside and outside surface (with other heat fusion jig heating) of tubing, until the inside and outside surface of internal ring wall outer surface, external annulus internal surface and tubing forms molten bath simultaneously; Then, tubing good hot melt is directly inserted in the joint socket that hot melt is good.Due to the internal surface of tubing and outer surface respectively with internal ring wall outer surface and the welding of external annulus internal surface of pipe fitting, so the connection reliability of tubing and pipe fitting is high.
But, pipe fitting being carried out in the process of hot melt with thermofusible spigot weld mold, because the gas in joint socket cannot be discharged smoothly, so after should when gases are heated, they expand, easily in joint socket, produce vapour lock, this vapour lock can make molten bath skewness on internal ring wall outer surface and external annulus internal surface, thereby has affected the hot melt quality of connection between pipe fitting and tubing, has reduced join strength and sealing effect.
Summary of the invention
The purpose of this utility model will overcome the existing defect of prior art exactly, and a kind of difficult generation vapour lock, thermofusible spigot weld mold that hot melt quality of connection is good are provided.
For achieving the above object, the thermofusible spigot weld mold that the utility model is designed, comprise the hot melt wall and the connecting plate that is connected to described hot melt wall one end of cylinder-like structure, in described hot melt wall, be at least provided with vertically an exhaust passage, whole described hot melt wall is run through in described exhaust passage, and the sidewall of described connecting plate is or/and be at least provided with an exhaust port being communicated with described exhaust passage on the end face of described hot melt wall dorsad.On mould, add exhaust passage by adopting, utilize this exhaust passage by the technological scheme of the Bas Discharged in joint socket, solved pipe fitting in prior art and in the time of hot melt, easily produced vapour lock, affect the problem of hot melt quality of connection, simple in structure and easy to use.
In such scheme, the quantity of described exhaust port is identical with the quantity of described exhaust passage.
Further, the quantity of described exhaust passage is at least 2, and described exhaust passage is evenly arranged along the circumferencial direction of described hot melt wall.Utilize like this exhaust of multiple exhaust passages more completely faster the gas in pipe fitting joint socket to be discharged, prevent vapour lock.
Further, described hot melt wall dorsad the end face of described connecting plate be provided with the annular groove being communicated with described exhaust passage.Design like this, increased the air inlet face of the inlet end of exhaust passage, can avoid molten knurl to stop up the inlet end of exhaust passage, ensured the smooth and easy of exhaust.
Further, described connecting plate is provided with the attachment hole for connecting heater.Be convenient to like this connect heater, conveniently pipe fitting carried out to heat treated.
Further, described attachment hole is arranged in the center of described connecting plate.Be convenient to heater to pipe fitting homogeneous heating.
The utility model adds exhaust passage by adopting on mould, utilizes this exhaust passage by the technological scheme of the Bas Discharged in joint socket, has solved pipe fitting in prior art and in the time of hot melt, has easily produced vapour lock, affects the problem of hot melt quality of connection.Have simple in structurely, easy to operate, be difficult for producing vapour lock, effective to the hot melt of pipe fitting, the join strength of pipe fitting and tubing is high, and the advantage such as good seal performance.
Brief description of the drawings

Fig. 2 is the right TV structure schematic diagram of Fig. 1.
Fig. 3 is the use status architecture schematic diagram of the utility model thermofusible spigot weld mold.
In figure: 1 exhaust passage, 2 annular grooves, 3 exhaust ports, 4 hot melt walls, 5 connecting plates, 6 attachment holes.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figures 1 to 3, the thermofusible spigot weld mold that the utility model is designed, comprise the hot melt wall 4 and the connecting plate 5 that is connected to hot melt wall 4 one end of cylinder-like structure, in hot melt wall 4, be at least provided with vertically an exhaust passage 1, whole described hot melt wall 4 is run through in exhaust passage, and the sidewall of described connecting plate 5 is communicated with 1 exhaust port 3 or/and be at least provided with one on the end face of described hot melt wall 4 dorsad with exhaust passage.The quantity of exhaust port 3 is identical with the quantity of described exhaust passage 1.When actual production, described hot melt wall 4 is overall structure with described connecting plate 5.
Particularly, the quantity of exhaust passage 1 is at least 2, and exhaust passage 1 is evenly arranged along the circumferencial direction of described hot melt wall 4.When actual production, generally adopt 4 exhaust passages 1, be evenly distributed on the circumferencial direction of hot melt wall, easy so completely by the gas discharge in pipe fitting joint socket.The hot melt wall 4 dorsad end face of described connecting plate 5 is provided with the annular groove 2 being communicated with described exhaust passage.Described connecting plate 5 is provided with the attachment hole 6 for connecting heater.Attachment hole 6 is arranged in the center of described connecting plate 5.
Using process of the present utility model is as follows:
First, the attachment hole of this mould 6 is connected on heater, mould is enclosed within the joint socket of pipe fitting on the hot melt wall 4 of this mould after heating up, until the inside and outside surface of pipe fitting internal ring wall outer surface, external annulus internal surface and tubing forms molten bath; Meanwhile, with the inside and outside surface of other heat fusion jig heating tubing, until form molten bath; Then, then by tubing good hot melt directly insert in the joint socket that hot melt is good.This mould, in the process of thermofusible spigot welding, utilizes the exhaust passage 1 on hot melt wall naturally the gas in joint socket to be discharged smoothly, avoids producing vapour lock, to strengthen sealing effect.
