Die cavity nut is coordinated with the screw thread of interior guide pin bushing；
Inner core die head includes tapered portion, threaded portion, and threaded portion is coaxially concentric with threaded portion, and inner core die head offers one along axis and goes out
Core is bored a hole, and the outside wall surface of threaded portion is provided with screw thread, and threaded portion is connected locking by screw thread and is coordinated with the screwed hole on interior guide pin bushing.
Further, the screw for extending radially into outer catheter, inner catheter and spiral shell are installed at the screw hole on outer catheter
Silk is contradicted and is coordinated, by with the matching relationship of screw and then ensureing the perforate for making the perforate of inner core die head and external diameter mould in same axle
On line.
The invention also discloses the rubber roll forming process based on the device, specifically includes following steps：
Step one：Supporting inner core die head is selected according to the diameter of rubber roll core, the inner core die head for choosing is screwed on interior guide pin bushing；
Step 2：Cavity length position according to corresponding to sizing material and binding agent species determine sizing material pressure, specifically will
Die cavity nut is fastened on the relevant position of interior guide pin bushing of inner core die head of working good.
Step 3：The interior guide pin bushing for assembling and outer bush are installed together, first the interior guide pin bushing for assembling are put into outer
In guide pin bushing, with nut-locking outer bush before guide pin bushing, and with screw by the interior guide pin bushing adjustment for assembling, the center for being fixed to outer bush
Locknut after external diameter die sleeve, guide pin bushing is then fixed and is tightly locked on outer bush by position；
Step 4：The connection mouth of pipe on outer bush is connected with the discharging opening of extruder, after the completion of connection, starts injecting glue, meanwhile,
The mating holes of glue Kun cores locknut from before guide pin bushing is inserted in interior guide pin bushing and stretched out from the core perforation that goes out of inner core die head；
Step 5：Be wrapped by sizing material rubber roll be molded into pressing out from external diameter after, length finer wire is by unnecessary glue as needed
Material excision.
Present configuration is reasonable, process is simple, is not affected by rubber roll length in process of production, the diameter of rubber roll roller core
Adjusted by inner core die head, the external diameter of rubber roll is that encapsulated thickness is controlled by external diameter die sleeve, sizing material is regulated and controled by die cavity nut
Pressure, can be adapted to the molding of different size model rubber roll simultaneously, forming process streamlined, improve production efficiency and once
Rubber roll ratio of briquetting, reduces the rear processing stock removal of rubber roll, improves the utilization rate of sizing material, simultaneously because technological equipment quantity
Greatly reduce, convenient management reduces production cost, and also the later process for rubber roll molding is laid a good foundation.

Body says, is on the relevant position of the interior guide pin bushing 2 that die cavity nut 6 is fastened to inner core die head 7 of working good, die cavity nut 6 it is another
The effect of one weight is to be fitted close to prevent sizing material from inversely flowing out with locknut before guide pin bushing 3,.By the interior guide pin bushing 2 for assembling and outer bush 1
It is installed together.Specifically first the interior guide pin bushing 2 for assembling is put in outer bush 1, and external diameter mould 8 is inserted after guide pin bushing
In locknut 4, the locking outer bush 1 of locknut 4 after guide pin bushing is then reused, is combined after fixing, and will be filled with screw insertion screw hole 9 is interior
The interior guide pin bushing 2 for preparing adjusts, is fixed to the center of outer bush 1, makes the perforate of inner core die head 7 exist with the perforate of external diameter mould 8
On same axis.The connection mouth of pipe 9 on outer bush 1 is connected with the discharging opening of extruder, after the completion of connection, starts injecting glue.As schemed
Shown in 3-5, the mating holes of glue Kun cores locknut 3 from before guide pin bushing is inserted in interior guide pin bushing 2 and stretched from the core perforation that goes out of inner core die head 7
Go out, after rubber roll core is by injection pressure sizing material cladding, advance in interior guide pin bushing 2 under injection pressure impetus, until from external diameter mould 8
Opening is released.After being wrapped by the rubber roll of sizing material out, according to the length of design requirement, unnecessary sizing material is cut off with finer wire,
Again injecting glue is used again.
Above example is the optimal enforcement example of the present invention, not makees any pro forma restriction to the present invention, any ripe
The technology contents that professional and technical personnel is known possibly also with the disclosure above are changed or are revised as the equivalent reality of equivalent variations
