Problems solved by technology

[0004] In addition, metal foreign matter with a diameter larger than the nozzle hole and the mold inlet will be blocked in the channel. At this time, as long as one is blocked in the channel, production will be affected, and the nozzle or mold must be disassembled for maintenance. Caused serious distress, but also caused unnecessary economic losses

Abstract

The invention discloses a filtering nozzle. The filtering nozzle comprises an auxiliary nozzle filter element, a flange connector filter element and at least one filter element, wherein the filter element is of a cylinder structure with a filter cavity filter element, a plurality of groove filter elements are arranged at intervals in the axial direction of the periphery of the filter element at certain positions away from the near end, a far-end opening of the groove filter element communicate with a nozzle opening filter element, a plurality of first filter hole filter elements communicating with the filter cavity filter element are arranged at the bottom of the groove filter element, and the aperture of the first filter hole filter elements is smaller than that of the nozzle opening filter element. According to the filtering nozzle, the filter element with grooves is adopted, the number of filter holes is increased, the filter area is enlarged, and the grooves are formed in the outer portion, so that machining is convenient, filtered plastic can be effectively concentrated in the grooves to achieve the uniform confluence effect, and the overall strength of the filter element can be improved, and the situation that the filter element is broken when blocked scrap iron is much and the borne pressure is larger is avoided.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to a filter nozzle assembled at the front end of the injection molding machine. Background technique [0002] Nowadays, the types of plastics in the injection molding industry are constantly updated, and their performance is continuously improved. The market competition is very fierce, and the profits of processing companies are getting lower and lower, and the injection molding industry is even more fierce. It is well known that the three most critical factors in the injection molding industry are raw materials, machines, and molds. Among them, the cost of raw materials is often very high. In order to reduce costs, recycled materials (secondary or multiple crushing) are commonly used in the injection molding industry. mixed with fresh ingredients). [0003] In the process of returning materials, when the defective products and nozzles are crushed, it is easy for...
