Abstract
A rotary sealing mechanism for a threaded mandril of an injection mould comprises a threaded mandril, and is characterized in that a rotary seal ring and a planar framework seal ring are mounted at the lower end of the threaded mandril. An upper pressure plate connected with a lower pressure plate is mounted outside the rotary seal ring and the planar framework seal ring, a cooling waterway is arranged in the lower pressure plate, and a cooling copper tube connected with the cooling waterway is mounted inside the threaded mandril. Since a cooling device is disposed inside the threaded mandril, product forming parameter is stable and parts cannot be blocked. Furthermore, the rotary sealing mechanism is long in service life, and product quality can be guaranteed.
Description
Technical field
The utility model relates to a kind of mould of plastics screw thread fuse rotating seal mechanism, belongs to the mould of plastics field.
Background technology
Adopt injection mold to produce plastic product, for example be with the product with screw thread (internal thread and external screw thread), this series products generally all adopts the transmission of hydraulic motor driven gear when taking off screw thread, is extracted out by the rotation of gear driven screw thread fuse and finishes.Prior art screw thread fuse is because work is in rotation status when (demoulding), can't seal, do cooling device so have no idea, the temperature of producing the rear thread fuse for a long time is more and more higher, expand after being heated, stuck easily between parts, service life is short, to such an extent as to the size molding parameter instability at product screw thread place can't guarantee product quality.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of employing rotatory sealing mechanism is provided, cooling device is done in screw thread fuse inside in rotation, make the formed product parameter stability, can be not stuck between parts, long service life, the injection mold screw thread fuse rotating seal mechanism of production assurance.
The technical scheme of the utility model injection mold screw thread fuse rotating seal mechanism is: comprise the screw thread fuse, it is characterized in that described screw thread fuse bottom installation rotating seal ring peace facial bone frame sealing ring, rotating seal ring peace facial bone frame sealing ring is installed pressing plate outward, top board connects lower platen, be shaped on cooling water channel in the lower platen, cooling copper tube is installed in the described screw thread fuse, and cooling copper tube connects cooling water channel.
Injection mold screw thread fuse rotating seal of the present utility model mechanism, rotating seal ring peace facial bone frame sealing ring has been installed in described screw thread fuse bottom, rotating seal ring peace facial bone frame sealing ring is installed pressing plate outward, top board connects lower platen, upper and lower pressing plate kills rotating seal ring peace facial bone frame sealing ring, when the screw thread fuse during at rotating stripping demoulding rotating seal ring peace facial bone frame sealing ring do not come off, reach sealing effectiveness.Be shaped on cooling water channel again in lower platen, in described screw thread fuse cooling copper tube be installed, cooling copper tube connects cooling water channel, makes cooling water be sprayed directly on to the top of screw thread fuse, and fully cooling-part makes the parts long service life, guarantees product quality simultaneously.
Description of drawings
Fig. 1 is the utility model injection mold screw thread fuse rotating seal mechanism structure schematic diagram.
The specific embodiment
The utility model relates to a kind of injection mold screw thread fuse rotating seal mechanism, as shown in Figure 1, comprise screw thread fuse 1, it is characterized in that described screw thread fuse 1 bottom installation rotating seal ring 2 peaceful facial bone frame sealing rings 3, the rotating seal ring 2 peaceful facial bone frame sealing ring 3 outer pressing plates 4 of installing, top board 4 connects lower platen 5, is shaped on cooling water channel 6 in the lower platen 5, in the described screw thread fuse 1 cooling copper tube 7 is installed, cooling copper tube 7 connects cooling water channel 6.The technical program has been installed rotating seal ring 2 peaceful facial bone frame sealing rings 3 in described screw thread fuse 1 bottom, the rotating seal ring 2 peaceful facial bone frame sealing ring 3 outer pressing plates 4 of installing, top board 4 connects lower platen 5, upper and lower pressing plate 4,5 kills rotating seal ring 2 peaceful facial bone frame sealing rings 3, when screw thread fuse 1 during at rotating stripping demoulding rotating seal ring 2 peaceful facial bone frame sealing rings 3 do not come off, reach sealing effectiveness.Be shaped on cooling water channel 6 again in lower platen 5, cooling copper tube 7 is installed in described screw thread fuse 1, cooling copper tube 7 connects cooling water channel 6, make cooling water be sprayed directly on to the top of screw thread fuse 1, fully cooling-part makes the parts long service life, guarantees product quality simultaneously.
