Abstract
The utility model relates to a novel injection head seal structure, including injection head, seal ring groove, sealing washer, connecting rod, be equipped with the seal ring groove on the face of cylinder of injection head, install the sealing washer on the seal ring groove, the injection head bottom is equipped with the connecting rod, the connecting rod passes through the screw with the injection head and links to each other. The cylindrical surface of the injection head is additionally provided with an annular sealing ring groove, and a sealing ring form is used, so that the blocking phenomenon of the injection heads of most molds during injection and mold withdrawal is avoided, and the service life of the injection heads is prolonged. The cooperation mode adopts flexible fit, and flexible fit makes the requirement of fit size reduce to reduce the degree of difficulty of processing, used elastic seal circle, compensatied the clearance after the wearing and tearing, reduce sealed wearing and tearing, increased life.
Description
Technical Field
The utility model belongs to the technical field of it is sealed, concretely relates to novel injection head seal structure.
Background
The sealing structure of the injection head used in the existing equipment is 'gap sealing', and when the gap between the charging barrel and the injection head is 0.003-0.005, the plastic sealing material for injection cannot overflow from the gap. Because of the clearance sealing structure, a certain gap exists on the friction surface, and the friction is used in a long-time high-pressure environment, so that the abrasion is difficult to avoid. After wear, the gap gradually expands, so that the molding compound overflows between the gaps and adheres to the friction surfaces after curing, and during the next second injection molding, the molding compound becomes the main medium of the worn injection head. And the sealing gap is continuously enlarged due to repeated and long-time flash-residue-abrasion, and finally the sealing gap is replaced after losing the functional requirements. The higher processing precision makes the processing and assembly requirements of the charging barrel and the injection head very high, and the process difficulty is greatly improved.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above problem, provide a novel injection head seal structure, increase the sealing washer form, the injection head of having solved most of moulds is injecting and is withdrawing from the card pause or pause phenomenon of mould time, has prolonged the life of injection head.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel injection head seal structure, includes the injection head, be equipped with the seal ring groove on the face of cylinder of injection head, install the sealing washer on the seal ring groove, the sealing washer adopts elastic seal circle, through the inseparable pressfitting of sealing washer mounting plate on the seal ring groove, the injection head bottom is equipped with the connecting rod, the connecting rod links to each other with the injection head.
Further: the sealing ring groove is an annular sealing ring groove;
further: the connecting rod is connected with the injection head through a screw, and the screw is an M6 or M8 internal thread screw;
further: the sealing structure adopts flexible matching.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the utility model provides a novel injection head seal structure, includes injection head, seal ring groove, sealing washer, connecting plate, has increased annular seal ring groove at the face of cylinder of injection head, uses the sealing washer form, has solved the injection head of most moulds and has injected and withdraw from the card pause or pause's phenomenon when the mould, has prolonged the life of injection head. The cooperation mode adopts flexible fit, and flexible fit makes the requirement of fit size reduce to reduce the degree of difficulty of processing, used elastic seal circle, compensatied the clearance after the wearing and tearing, reduce sealed wearing and tearing, increased life.
