Background technology
Along with the development of water dropper die industry, traditional cold runner die changes to high efficiency full hot runner mould gradually.Application hot flow path can shorten molding cycle, reduces waste material; Product cost can be reduced when producing in enormous quantities.Simultaneously because pressure in runner transmits, plastics forming temperature and injection pressure can be reduced, like this, both decreased the thermal degradation of plastics, and again reduced the internal stress of product.But the injection molding of the hot flow path of China's application is at present also not general, and its main cause has following 2 points:
1, more domestic heating element heater quality are unstable, often break down, particularly external heat Channels in use procedure, and repairing is changed extremely inconvenient, and impact is produced.
2, the hot-runner nozzle of external import is expensive, improve die cost, sometimes 40 ~ 50% are exceeded than cold runner die cost, thus improve the critical mass (namely mold injects product amounts can reduce goods cost higher than using hot runner mould during this quantity) of use hot runner mould injected articles, reduce the hot runner mould scope of application.And this nozzle is in use repaired and changes also extremely inconvenient.
Known by retrieving, there is the report about interior heated nozzle at present, its structure is made up of hot-runner nozzle and heating rod, heating rod is located in the chamber of hot-runner nozzle, the front end of hot-runner nozzle is semicircle shower nozzle, spray orifice is provided with at the center of semicircle shower nozzle, the inwall of hot-runner nozzle to heating rod outer wall between be annular heat plastic passages, the rear end of hot-runner nozzle is inserted in the installing hole of hot runner manifold, this interior heated nozzle is applicable to the many pouring heat runners of heating in plastic injection mould, but is not suitable for full hot flow path water dropper mould.
Summary of the invention
The purpose of this utility model is to provide one to be convenient to repair and changes, can reduce costs, improve service life, and structure simply, good airproof performance, easy to use, the interior heated nozzle of water dropper mould that is exclusively used in full hot flow path water dropper mould.
In order to reach above object, the technical scheme that the utility model adopts is: the interior heated nozzle of this water dropper mould, be made up of holder and heating mouth, it is characterized in that: described heating mouth front end is solid needle point body, connected as one by radian changeover portion between heating mouth to solid needle point body, heating mouth rear end is connected with the circular mounting groove interference fit of holder antetheca, be provided with heating rod in the chamber of described heating mouth, the overall diameter of heating rod is consistent with the interior diameter of heating mouth, and the length of heating rod is consistent with the length of the inner chamber of heating mouth, the degree of depth of the circular mounting groove of described holder antetheca is 1/4 of heating mouth length, the rear wall center of holder is provided with semicircle thermoplastic materials and enters groove, the sidewall entering groove at semicircle thermoplastic materials is provided with thermoplastic materials inflow entrance, export in the annular heat stream of plastic that is provided with for a week on the circular mounting notch edge of holder antetheca, thermoplastic materials inflow entrance to be exported with annular heat stream of plastic by inclined flow passage and is connected, thermoplastic materials enters from thermoplastic materials inflow entrance, the outlet of annular heat stream of plastic is flowed into along inclined flow passage, by the heating rod heating in the outlet of annular heat stream of plastic, again along the outer wall flow forward of heating mouth, and while flowing, while heating, finally along solid needle point body ejection.
The utility model is also implemented by following measure: described thermoplastic materials inflow entrance is provided with 3, one is located at the upside that semicircle thermoplastic materials enters the sidewall of groove, two other is located at the left and right side that semicircle thermoplastic materials enters the sidewall of groove, and to export with annular heat stream of plastic respectively by corresponding inclined flow passage and be connected.
Described heating rod is carbon crystal electrothermo rod, and the wire connecting carbon crystal electrothermo rod stretches out from the bottom side cinclides of holder, and is connected with temperature thermocouple; Certainly, heating rod also can be bought or orders goods in relevant factory according to actual needs.
The material of described heating mouth is identical with the material of cover half.。
The beneficial effects of the utility model are: the interior heated nozzle of this water dropper mould, owing to heating rod being located in heating mouth, and the front end of heating mouth is solid needle point body, rear end and the holder of heating mouth are interference fit, so without the need to sealing ring, interior heated nozzle good leak tightness, melt can not leak, and can not damage the circuit near passage or nozzle; Because heating heating rod and holder are assembly type, institute is so that repair and change, even if there is damaged condition once in a while, whole replacing also needs with the time very short, and due to required spare and accessory parts little, so structure simple, easy to use, can reduce costs, improve service life.Be specially adapted to full hot flow path water dropper mould.
