Description
Technical Field
The invention relates to the technical field of injection molds, in particular to a hot runner system which is not afraid of entering impurities.
Background
The hot runner technology has a history of four and fifty years abroad and a local production history of less than twenty years in China, is a necessary product for replacing the manual injection molding industry by improving the efficiency and the cycle, particularly is intelligent, does not have waste materials, and simultaneously improves the international competitiveness and reduces the cost; a set of common hot runner system imported abroad is hundreds of thousands, while only twenty-three thousands produced at home.
In the current injection molding industry, most injection molding factories reduce the plastic cost, and a plurality of plastic manufacturing enterprises adopt recycled granules, secondary recycled materials and tertiary recycled materials, so that the purposes of energy conservation and emission reduction are facilitated, the workshop automation is realized, and a needle point type and needle valve type hot nozzle is required to be used, otherwise, the automation degree of the injection molding enterprises is not high to a certain extent.
However, as the recycled plastic materials contain more or less impurities such as scrap iron, aluminum scraps, heterogeneous plastics and the like, even if only one millimeter of impurities can block the hot nozzle glue outlet hole, the lower die is stopped to remove the hot runner for cleaning.
If the hot nozzle glue outlet hole is blocked, a light person can lower the mold and remove the mold to inform a hot runner professional manufacturer to clean the mold at the fastest time and then can produce the mold eight hours in the front and back days, and the mold can be slowly produced two or three days, and then 180 tons of a small-tonnage injection molding machine can be used, so that the minimum loss of more than 2000 yuan per day is realized. The injection molding machine of thousands of tons of losses is five times more of this kind of little board, and can not guarantee again not stifled mouth after this washing again, heavy then iron fillings impurity etc. will go out directly also the department of gluing explode one, the front mould benevolence all can be abandoned. The problem that the front mold core is not solved in three, five or six days by re-manufacturing the front mold core is solved, and the front mold core is forgotten to fall. The problem that the front mold core is made again can be solved within three, five or six days, and the economic loss, the yield and the loss are directly counted by ten thousand units. And the recycled granules cannot be recycled, which is not beneficial to environmental protection, so that the development of a hot runner which can resist impurities is also needed by the current industry.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a hot runner system which is free from impurities, so that the hot runner system is free from impurities and meets the current needs of the industry.
In order to achieve the purpose, the technical scheme of the invention is as follows:
the utility model provides a hot runner system who is not afraid of into impurity, includes the flow distribution plate, the level sets up the flow distribution plate passageway in the flow distribution plate, set up perpendicularly in the flow distribution plate and with the hot runner hole of flow distribution plate passageway intercommunication, be linked together the hot runner nozzle with the hot runner hole, set up the flow distribution plate end cap under the flow distribution plate, set up the main feeding mouth directly over the flow distribution plate, nozzle passage in the hot runner nozzle passes through nozzle discharge gate and product die cavity intercommunication, the center of main feeding mouth is provided with the main feeding mouth passageway with flow distribution plate passageway intercommunication, the top of main feeding mouth is provided with the barrel of moulding plastics, the barrel of moulding plastics is provided with plastics impurity separation ware with the flow distribution plate passageway, the aperture has been seted up at plastics impurity separation ware's center and edge, aperture diameter on the plastics impurity separation ware.
As an improvement to the technical scheme, the plastic impurity separator is arranged at the upper end of the main feeding nozzle, the middle of the main feeding nozzle and the joint of the main feeding nozzle and the hot runner flow distribution plate.
