Abstract
The invention provides an integrated hot runner assembly process. The technical purpose is to provide an assembly process of an integrated hot runner system with simple process, tight matching and precise assembly. The integrated hot runner assembly process comprises a splitter plate; a plurality of splitter holes are formed on the splitter plate; the sizes of the splitter holes are slightly less than those of hot nozzles; the splitter plate is heated to a temperature more than 100 DEG C in an assembly process; the splitter holes on the splitter plate are subjected to hot expansion; and the hot nozzles are inserted in the splitter holes of the splitter plate. With the adoption of the integrated hot runner assembly process provided by the invention, the better sealing property is achieved; no glue leakage is ensured because the splitter plate is matched with the hot nozzles; and a hot runner structure has a longer service life, and is safer and more reliable to use. The integrated hot runner assembly process is applicable to be applied in the hot runner structure of a die.

Summary of the invention
Technical purpose of the present invention is to overcome in the prior art in the hot flow path structure, and the assembly technology of flow distribution plate and hot mouth exists the technology imperfection and causes the bad technical problem of product; Provide a kind of technology simple, cooperate closely and assemble accurate monoblock type hot flow path assembly technology.
For realizing above technical purpose, technical scheme of the present invention is:
A kind of monoblock type hot flow path assembly technology includes flow distribution plate, and it is characterized in that: said flow distribution plate is provided with several tap holes, and said tap hole undersized is in Re Zui; During assembling, flow distribution plate is heated to more than 100 ℃, the tap hole heat expansion on the flow distribution plate is inserted hot mouth in the tap hole of flow distribution plate.
Further, said tap hole one side is provided with pilot hole, and said hot mouth is provided with the gathering sill corresponding with said pilot hole, and lead inserts in the pilot hole, and the gathering sill on the hot mouth also accurately leads along the lead location.
Further, during assembling hot mouth is cooled to 0 ℃ to 10 ℃.
Further, said hot mouth uses stainless steel metal, and after hot mouth inserted in the tap hole, the flow distribution plate heat was delivered to heat and chews, and heat is chewed rapid heating and expansion, and hot mouth outer wall and tap hole inwall are closely cooperated.
Further, vertically being provided with direction recess in the said tap hole, said hot mouth is provided with the guiding raised line that cooperates with direction recess.
Further, said tap hole inwall is provided with shallow thread, and said hot mouth is provided with the screw thread with tap hole shallow thread corresponding matching, and the said depth of thread is set according to fitting temperature and the steel calculating rate of expanding with heat and contract with cold.
Further, said hot mouth uses elastic metallic, and hot mouth uses quantitative high-pressure hot gas in hot mouth interior expansion after inserting in the tap hole, and hot mouth outer wall and tap hole inwall are closely cooperated.
When implementing, the flow distribution plate temperature can be regulated in temperature more than 100 ℃ according to actual needs.
Useful technique effect of the present invention is: in application process, and the perfect cooperation between hot mouth and the hot runner flow distribution plate, hot mouth can be locked in flow distribution plate closely.The present invention designs ingenious; The cold and hot technical scheme that matches has unobviousness, and this scheme brought sealing property better, guarantees flow distribution plate and hot cooperating of chewing not to leak glue; Hot flow path structure longer service life; Use safety and reliability, compared with prior art, the present invention has outstanding substantive distinguishing features and significant technological progress.
