Abstract
The invention relates to a connecting structure of a metal insert and a plastic body. The connecting structure is composed of the metal insert and the plastic body; the metal insert is internally embedded in the plastic body; and the outer circle and the inner hole of the metal insert are respectively provided with a ring groove in which plastic materials can be filled. In injection molding, the metal insert is internally embedded in the plastic body, and because the plastic materials are respectively filled in the grooves of the outer circle and the inner hole of the metal insert, the leakage caused by inconsistent coefficient of linear expansion between the plastic body and the metal insert can be avoided.
Description
Technical field:
The present invention relates to pipeline, relate in particular to the plastic cement pipe fitting that is embedded with metalwork, the linkage structure of particularly a kind of metal insert and plastic body.
Background technique:
The plastic cement products of band damascene part is widely used, and can save metals resources.In the prior art, in order to strengthen combination force between metal embedded component and the plastic body preventing seepage, way is at damascene part outer peripheral surface groove to be set usually, this groove by Shooting Technique directly and plastic body be assembled into product.It is strong inadequately that but the metal insert of existing structure and plastic cement bulk junction are made a concerted effort, damascene part and plastic body junction plane place can produce the slit under long-term interior pressure and cold cycling effect, thereby have strengthened the risk of resultant metal inserter and plastics junction plane seepage.
Summary of the invention:
The object of the present invention is to provide the linkage structure of a kind of metal insert and plastic body, the linkage structure of described this metal insert and plastic body will solve in the prior art that metal insert and plastic body combination force are strong, the technical problem of seepage the slit appears and in junction plane.
The linkage structure of this metal insert of the present invention and plastic body is made of a metal insert and a plastic body, the material that described plastic body adopts is an atactic copolymerized polypropene, the material that described metal insert adopts is a copper, described metal insert is embedded in the described plastic body, constitute by a metal insert and a plastic body, described metal insert is embedded in the described plastic body, wherein, is provided with annular groove in the cylindrical of described metal insert and the endoporus.
Further, be filled with plastic material in the described annular groove.
Working principle of the present invention is: during injection moulding metal insert is embedded in the plastic body, because plastic material enters respectively in the annular groove of metal insert cylindrical and endoporus, can avoid the seepage that causes because of linear expansion coeffcient is inconsistent between plastic body and the metal insert under long-term interior pressure and the cold cycling effect.
The present invention and prior art are compared, and its effect is actively with tangible.The present invention all is provided with annular groove at the cylindrical and the endoporus of metal insert, plastic material can be filled in the inside and outside groove of damascene part when injection moulding, in the time of can preventing effectively that the damascene part from producing micro gap with plastic body under fluid pressure and long-term cold cycling effect, the phenomenon that liquid oozes out from inserts and plastic body junction plane.
Description of drawings:
Fig. 1 is the schematic representation of the linkage structure of a kind of metal insert of the present invention and plastic body.
Embodiment:
Embodiment 1:
As shown in Figure 1, the linkage structure of a kind of metal insert of the present invention and plastic body, constitute by a metal insert 1 and a plastic body 4, the material that described plastic body 4 adopts is an atactic copolymerized polypropene, the material that described metal insert 1 adopts is a copper, and described metal insert 1 is embedded in the described plastic body 4, wherein, groove 2 (at least one) is set on the cylindrical of described metal insert 1, and in the endoporus of metal insert 1, groove 3 (at least one) is set.
Claims (2)
1. the linkage structure of metal insert and plastic body, constitute by a metal insert and a plastic body, the material that described plastic body adopts is an atactic copolymerized polypropene, the material that described metal insert adopts is a copper, described metal insert is embedded in the described plastic body, it is characterized in that: be provided with annular groove in the cylindrical of described metal insert and the endoporus.
