Manufacturing cost.
Preferably, the outlet of the hot flow path in the feed block with described to scrape sheet mold upper at scraping blade step port
Feed inlet docking.It occurs bending and deformation in this way, can avoid scraping blade in injection molding, and then can avoid scraping blade and occur when in use
Catching phenomenon improves the using effect of scraping blade.
Preferably, cylinder, oil cylinder or motor can be selected in the driving device.
Preferably, scraping blade step port feeding device further includes bracket, is provided on the bracket and wears the needle-valve
Needle installation through-hole.In this way, can be rack-mount by feed block, it, can be according to manufacture during manufacturing scraping blade
It needs mobile bracket to export the hot flow path of feed block to dock with the feed inlet for scraping sheet mold or move up out from sheet mold is scraped, operate
It is simple and convenient.Further, it is provided with needle locating piece on the bracket, which is mounted on the bracket away from institute
The side of feed block is stated, and is provided with the location hole being connected to the installation through-hole in the needle locating piece.In this way, can avoid valve
Needle is damaged even run-off the straight in telescopic process, influences the plugging effect of needle.It is further preferred that the installation through-hole is
Counterbore, and the needle locating piece is mounted in the countersunk head slot of the counterbore, it is easy for installation and convenient for positioning.
Preferably, the bracket is to connect the H-type frame formed, and the two of support frame as described above by link block and two support frames
End is each provided with the installation through-hole.Such bracket, structure is simple, easy to make.
