Abstract
The utility model discloses a water pipe joint for mould cooling water route, which comprises a hexagon head which is made of plastics, a long tube interface which is formed by the extension of one side of the hexagon head and a screw-threaded joint which is formed by the extension of the other side of the hexagon head, wherein the side face of the hexagon head which faces to the screw-threaded joint is a cone transition surface. Since the utility model adopts such a structure, when the cone surface and a chamfer of the end surface of a threaded hole in a mould are mutually impacted, the cone surface can generate certain plastic deformation to lead the chamfer to tightly attach to the cone surface so as to achieve the purposes of seal and leakageproof; when the angle of a cone angle of the cone surface is approximately larger than the angle of the chamfer of the end surface of the threaded hole, the sealing effect of the utility model is optimal; the water pipe joint can be made of transparent plastics to be convenient to observe the situation of water flow; the water pipe joint can also be made of color plastics to be convenient to distinguish.
Description
One, technical field
The utility model relates to a kind of water pipe adapter, particularly a kind of water pipe adapter of the cooling water channel of using on injection moulding or blowing industry mould.
Two, background technique
The existing water pipe adapter that is used for the mold cools down water route is made by the metal machining usually, and as shown in Figure 1, its structure is that the stage casing is the hexagon head that screws usefulness, is the long tube interface that the grafting flexible pipe is used in the first side of hexagonal, and opposite side is the inipple that is connected with mould.Because water pipe adapter and mould all are to be made by the higher metal of rigidity, by the characteristic of metal as can be known, interconnect part at internal and external threads and can leave certain clearance, cause leakage of cooling water.Common leak-proof measure is to wrap sealant tape at inipple in advance to screw in the tapped hole on the mould again, utilize sealant tape to fill the gap, perhaps on hexagon head is positioned at the end face of inipple one side, increase a gasket seal and also can play effect same to reach sealing purpose.But, this kind water pipe adapter is to be made by the metal machining, cost is higher, and in use also must increase miscellaneous part for leakproof, both having increased the complexity of installing also makes cost further improve, in addition, this water pipe adapter is after accident is damaged, and the thread section that breaks at mould inside is difficult for taking out.
Three, summary of the invention
1, goal of the invention: the purpose of this utility model provides that a kind of cost is lower, easy to use, the water pipe adapter in the mold cools down water route of good leak-proof effect.
2, technological scheme: the water pipe adapter in mold cools down described in the utility model water route, comprise the hexagon head that is made of plastics, from the extended long tube interface of the first side of hexagonal and from the extended inipple of opposite side, be the conical transition face at hexagon head towards the side of inipple.
The cone angle of conical surface preferably is slightly larger than tapped hole end face chamfering.
Water pipe adapter can also be made by transparent plastic or colored plastic.
3, beneficial effect: the utility model adopts plastics to make, reduced cost of production with respect to metal water pipe adapter, it is provided with the conical transition face at hexagon head towards the side of inipple, when water pipe adapter being screwed in the mould tapped hole, when conical surface was contacted with tapped hole end face chamfering, under the effect that screws power, conical surface can produce certain plastic deformation, itself and tapped hole end face chamfering are fitted tightly, to reach the effect of sealed against leakage; In addition, if make the cone angle of conical surface be slightly larger than tapped hole end face chamfering, the best results of sealing this moment.Adopt such structure to save the step that swathes adhesive tape or use gasket seal at inipple, more convenient to use, and also more economical; And because plastics are more crisp, when this water pipe adapter after accident is damaged, the part that breaks at mould inside can be picked out easily.When it is made by transparent plastic, in use can observe the situation of current easily; And when using colored plastic to make, can be used for identifying different temperatures cooling water or be used for dissimilar moulds.
Four, description of drawings
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is a structural representation of the present utility model.
Five, embodiment
Referring to accompanying drawing 2, water pipe adapter of the present utility model is made by the plastics single forming, and material can be PC, POM or other plastics kind.Its structure is by the hexagon head 1 that is positioned at the stage casing, forms to the extended long tube interface 2 of the first side of hexagonal and to the extended inipple 3 of opposite side.Hexagon head 1 is used for tool using and screws water pipe adapter; Long tube interface 2 is pegged graft with cooling water flexible pipe 5, and it is provided with annular groove 6, is used with beam ring 7 fastening pieces such as grade, plays the effect of locking leakproof; Inipple 3 is connected and fixed by the tapped hole on outside thread and the mould, is conical transition face 4 at hexagon head 1 towards the side of inipple 3.The cone angle of circular cone transitional surface 4 preferably is slightly larger than the angle of mould upper screwed hole end face chamfering.This water pipe adapter can be made by transparent or colored plastic.
Claims (4)
