By analysis, the technical solution that the forming method and structure with the application of runner are taken in above patent document is equal It is different.

To sum up, the node runner forming method and flow passage structure for how designing a kind of liquid rubber composite node, had made it both It can guarantee that liquid in liquid cavity is only flowed along the length direction of runner, without lateral channelling occurs, that improves product can Can be conducive to Product Assembly again by property is technical problem urgently to be solved.

Summary of the invention

It is multiple the technical problem to be solved by the present invention is in view of the deficiencies in the prior art, provide a kind of liquid rubber The node runner forming method and flow passage structure for closing node both can guarantee the liquid in liquid cavity only along the length side of runner The reliability of product is improved, and be conducive to Product Assembly without lateral channelling occurs to flowing.

In order to solve the above technical problems, the technical solution used in the present invention are as follows: a kind of section of liquid rubber composite node Point runner forming method is that housing is arranged to inside and outside two, and internal housing is runner housing, and outer jacket is whole outer Set is provided with flow path groove on the outer peripheral surface of runner housing, and for flow path groove around being distributed on the outer peripheral surface of runner housing, entirety is outer Set is assemblied in outside runner and puts on, and the notch formation node runner for sealing up flow path groove is blocked using the inner peripheral surface of integral sleeve, is made Obtaining liquid can only flow along the length direction of flow path groove, will be connected between multiple liquid cavities by node runner Come.

Preferably, by the design of terminations of the flow path groove at three types, respectively perpendicular type end, bias type end Portion and closing in type end；It, can be using the end of the flow path groove of above-mentioned three types when the end construction at flow path groove both ends is identical Any one in structure can be using the flow path groove of above-mentioned three types when the end construction at flow path groove both ends is not identical Any two kinds in end construction.

Preferably, the perpendicular type end includes interconnected horizontal run slot and vertical run slot, horizontal run slot One end be connected with one end of vertical run slot, the other end of horizontal run slot is connected with liquid cavity.

Preferably, the groove width J1 of horizontal run slot and the groove width J2 of vertical run slot are equal.

Preferably, closing in type end includes closing in flow path groove one, closing in flow path groove two and closing in flow path groove three, is closed up One end of flow path groove one is connected to by closing in flow path groove two with one end of closing in flow path groove three, the other end of closing in flow path groove one It is connected to liquid cavity；The groove width J3 of closing in flow path groove one is greater than the groove width J4 of closing in flow path groove two, the slot of closing in flow path groove three Wide J5 is greater than the groove width J4 of closing in flow path groove two.

Preferably, the specific forming method of liquid cavity is as follows: multiple spaces, spatial class are first dug out on middle spacer sleeve It is similar to through hole shape, outboard end and inner end are openning shape；When space inner end opening is sealed, be by mandrel in After bonding together between spacer sleeve by the vulcanization of rubber, the inner end port in space is blocked using the rubber after vulcanization；It will When end opening is sealed on the outside of space, it is to cover curved cover plate on the middle spacer sleeve after hollowing out, is blocked using curved cover plate The firmly outboard end port in space；Using the above method, so that multiple spaces form multiple liquid cavities；

It is assembled in runner housing after liquid cavity is formed, then by middle spacer sleeve.

Preferably, runner through-hole is provided on the end grooves bottom of flow path groove, flow path groove passes through runner through-hole and liquid cavity It is connected.
