Embodiment Construction

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0017] refer to Figure 1-3 , a self-cleaning anti-clogging type injection molding nozzle, including a mounting block 1, the upper end surface of the mounting block 1 is provided with a circulation groove 2 for injection of molten raw materials, and the bottom groove wall of the circulation groove 2 is vertically connected to the lower end surface of the mounting block 1. The discharge pipe 3 is directly opened, and the lower end of the flow tank 2 is symmetrically provided with a placement slot 4. Each placement slot 4 is horizontally rotated by a rotating shaft 5 and installed with a rotating roller 6. The two rotating rollers 6 are equipped with a filter. net 7, a...

Abstract

The invention discloses an self-cleaning anti-blocking type injection molding pipe orifice which comprises a mounting block, wherein a circulating slot is formed in the upper end surface of the mounting block, a discharging tube is vertically arranged between the bottom slot wall of the circulating slot and the lower end surface of the mounting block, and placing slots are symmetrically formed inthe lower end of the groove wall of the circulating slot; a rotating roller is rotatably mounted in each placing slot through a rotating shaft; the two rotating rollers are jointly sleeved with a filter screen which is connected to the slot wall of the circulating slot in a sealing and sliding mode, and a brush plate is fixedly connected to the slot wall of each placing slot. According to the invention, during repeated injection molding, the magnetic repulsion between an electromagnet, a first permanent magnet block and a second permanent magnet block and the elastic force of a first spring and a second spring are utilized to automatically drive the filter screen to perform one-way transmission after each injection molding is finished, so that the filter screen can be continuously cleanedin cooperation with the brush plates, and thus, impurities can be prevented from blocking the discharging tube and the filter screen without repeated disassembly, and the use effect is good.

Description

technical field [0001] The invention relates to the technical field of injection molding equipment, in particular to a self-cleaning and anti-clogging injection nozzle. Background technique [0002] In the injection molding process, the hydraulic system needs to inject the molten plastic raw material into the mold cavity through the nozzle of the injection machine. In order to ensure that the molten plastic raw material has a very high flow rate when it is injected from the nozzle, the diameter of the traditional injection nozzle is small. [0003] However, in actual use, many raw materials contain some impurities, or the raw materials are not evenly melted, which leads to the blockage of the injection nozzle. After the injection nozzle is blocked, it needs to be disassembled and cleaned in time, which greatly affects the injection molding process. When the injection nozzle is seriously blocked, the pressure of the external hydraulic system is too large, which may even cause...
