On, which is internally provided with a sprue connected with melten gel barrel, and a point sebific duct other end is provided with one and is connected with allotter
Link slot, the link slot is connected with sprue, and a point sebific duct outer wall is respectively arranged with the first recess, the second recess and is located at
Between stopper section between first recess and the second recess, first recess, the second recess and stopper section and sleeve lining leave
Gap, forms melt plastic cement and flows into secondary channels;Allotter is mounted between nozzle and point sebific duct, is provided with and above-mentioned pair
First sizing material ostium of flow passage and the second sizing material ostium connected with above-mentioned sprue, the allotter its first rank
Connecing during end is connected to the link slot of point sebific duct and a valve stem chamber that can accommodate valve rod being formed with link slot, its second cohesive end is pacified
It is mounted on sleeve and is connected with nozzle;Above-mentioned valve rod includes connecting pin and head, and its connecting pin activity is plugged on the of allotter
On one cohesive end, its head is exposed to outside allotter and is contained in valve rod room, can move forward and backward until withstanding sprue runner
Mouthful;Cross cushion rubber be socketed on allotter and point sebific duct convergence part outer wall and with allotter and divide a sebific duct convergence part outer wall to leave to be available for
The gap that melting sizing material flows through, above-mentioned cushion rubber of crossing can be moved forward and backward until contacting with the stopper section of point sebific duct.
The present invention has the advantages that:
Injection machine of the present invention double color injection nozzle, the melting sizing material in its sprue and secondary channels will not flow back, structure
It is simple and can realize that such as the clear double color injection of various ways double color injection, blending double-color are injected and sandwich injection.
Description of the drawings
Fig. 1 is the structural representation of injection machine double color injection nozzle of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the invention will be further described, understands this in order to clearer
The claimed technological thought of invention.
As shown in Figure 1 injection machine of the present invention double color injection nozzle, including for being fixedly connected with injection machine pair rubber melting cylinder
