Abstract
The utility model discloses a kind of monoblock type hot runner injection mould of improvement, belong to injection molding technical field.It mainly comprises main burner, driving needle valve module, bearing ring, spline pin, support ring, nozzle body, conehead needle, solid plate, sprue bush, centrally-located cover, driving needle valve module comprises oil transportation mouth, drives oil cylinder, cylinder cap, sealing ring, piston, oil seal washer, back-up ring, lock-screw, piston packing, cooling water pipe, oil cylinder is driven to be arranged on runner plate, without convex shoulder on nozzle body, sprue bush is fixed on solid plate, and conehead needle is driven by oil cylinder piston.Its advantage is: decrease melten gel and leak possibility, nozzle convex shoulder section, avoid the impact of mismachining tolerance on installation accuracy of solid plate, avoid nozzle convex shoulder to the heat transfer of cover half plate hole seat, make the cooling of solid plate more effective, the Temperature Distribution of TOP-TIP is tending towards reasonable, and monoblock type hot flow path is at the install and adjust of injection molding simultaneously, and specific pressure articulated hot flow path is much simple and direct.
Description
Technical field
The utility model relates to injection molding technical field, is specially a kind of monoblock type hot runner injection mould of improvement.
Background technology
Along with Hot runner Technology extensive use in plastic injection mould, traditional runner plate and nozzle connecting mode under stress is progressively substituted by all-in-one-piece TOP-TIP, in recent years, big-and-middle-sized moulding is when adopting the injection of needle valve multiinjector, also the thread connection of nozzle and runner plate is adopted, all-in-one-piece TOP-TIP uses for a long time, the little product of a multi-cavity mold adopts thimble-type nozzle, when spacing between small nozzle axis is 10 ~ 20mm, nozzle thread connection runner plate, causes hot runner system structure compact.
In recent years, panel computer and game machine, the consumption electronic products such as mobile phone are many, output is very large again, while moulding demand increases, the requirement of injection technique is also more and more higher, now, needle jet is more and more higher than the application percentage of open nozzles, if plastic melt directly injects the surface of moulding at the cast gate of needle jet, then gate vestiges can highlight on the working surface of thin plate, because cast gate is on the thermodynamic barrier of hot-runner nozzle and cover half die cavity, variations in temperature is large, the shear rate of plastic melt mold filling is high, flowing instability, on moulding, cast gate near zone often has the defects such as flowing trace, have impact on product quality and the qualification rate of injection member greatly.
Utility model content
The utility model is for the technical problem that solves for providing a kind of monoblock type hot runner injection mould of improvement, and it adopts hot flow path and cold runner composite pouring system.
The utility model technical solution problem adopts following technical scheme:
A kind of monoblock type hot runner injection mould of improvement is provided, it mainly comprises main burner, driving needle valve module, bearing ring, spline pin, support ring, nozzle body, conehead needle, solid plate, sprue bush, centrally-located cover, it is characterized in that: described driving needle valve module comprises oil transportation mouth, drive oil cylinder, cylinder cap, sealing ring, piston, oil seal washer, back-up ring, lock-screw, piston packing, cooling water pipe, described driving oil cylinder is arranged on runner plate, without convex shoulder on described nozzle body, described sprue bush is fixed on solid plate, described conehead needle is driven by oil cylinder piston.
