The utility model discloses a slag-proof structure of injection moulding machine nozzle. The nozzle comprises a nozzle head and a nozzle seat. The nozzle head has a nozzle hole, and the nozzle seat has an inner hole of the nozzle seat. The nozzle hole is connected with the inner hole of the nozzle seat to form a glue-producing structure. A filter head is arranged in the inner hole of the nozzle seat, and the filter head is provided with a filter head for glue-passing. The back part of the filter head has the tail part of the filter head, along the side wall surface of the tail part of the filter head is provided with a number of glue slots, the inner diameter of the glue slot is smaller than the inner diameter of the nozzle hole; the nozzle hole is connected with the inner hole of the filter head, and the glue slot is connected with the inner hole of the filter head. The utility model provides a filter head with a gum inlet slot in the nozzle seat, and the diameter of the gum inlet slot is smaller than the diameter of the nozzle hole, so as to protect the nozzle hole by blocking impurities and the like through the gum inlet slot. When there are more sundries, just remove the nozzle head and pull out the filter head, so that sundries can be extruded automatically. Cleaning process is convenient and fast, without burning and cleaning, can protect the nozzle components, but also protect the environment.

一种注塑机射嘴防渣结构
本技术涉及注塑设备
,具体涉及一种注塑机射嘴的防渣过滤结构。
技术介绍
注塑是工业生产中广泛应用的工艺之一,其通过注塑机将塑料融化成熔融状态,经过射嘴注射到模具中实现成型。然而,由于塑料中通常会有一些添加物甚至杂物,因此在注塑过程中不过会发生杂物堵塞射胶孔(射嘴孔)的状况,影响正常的注塑作业,因此需要经常清理射嘴内的杂物。然而,由于传统的射嘴结构设计不够合理,导致在清理时存在以下问题,第一,清理杂物的时间长,不易清理,且清理完后会产生不少废料;第二,用火烧是较常用的办法,但火烧会污染环境;第三,频繁地清理射嘴易损坏射嘴、大嘴、发热圈及感温线。
技术实现思路
本技术针对现有技术存在的缺点,提供一种结构简单、设计合理、清理方便、不需采用火烧、清理速度快的注塑机射嘴防渣结构。为解决上述技术问题,本技术采用如下技术方案:一种注塑机射嘴防渣结构,射嘴包括有射嘴头和射嘴座,两者通过螺纹连接固定,射嘴头中具有射嘴孔,射嘴座则具有射嘴座内孔,射嘴孔与射嘴座内孔连通形成出胶结构,其特征在于:在射嘴座内孔中安装有一滤头,滤头中具有用于过胶的滤头内孔;滤头的后部具有滤头尾部,沿滤头尾部的侧壁表面开设有若干延伸方向与射嘴座内孔方向相同的进胶槽,进胶槽的内径小于射嘴孔的内径;所述滤头内孔的尾端延伸至与滤头尾部相接的位置,而滤头内孔的前端与射嘴孔对接连通;所述进胶槽与滤头内孔连接,滤头嵌入在射嘴内孔中,进胶槽与射嘴内孔的孔壁之间的空间形成进胶及过滤结构。进一步地,所述进胶槽为半圆形结构,若干进胶槽均匀分布在滤头尾部的侧壁表面。进一步地,在滤头尾部的前方设有一圈内 ...
