Injection end piece with open flow channel and injection molding processing device with the injection end piece

Abstract

The present invention provides a sprue end element with opened runner, wherein the sprue end element is movably interposed between a polymer heating and extrusion outlet and a feeding port of a mould and is located between a mould holding mechanism which is used for opening or closing the mould and the mould. When the sprue end element is applied in a high-molecular processing process, the sprue end element can allows a flow path for melting a high molecular raw mateiral to flow after pouring is completed, thereby enabling operators to directly take out the cured high molecular raw material in the flow path. By means of the sprue end element, a material cleaning process is convenient to carry out.

Description

technical field [0001] The invention relates to polymer molding processing technology, in particular to an injection end piece with an open flow channel and an injection molding processing device with the injection end piece. Background technique [0002] In the previous application for the invention patent of Taiwan No. 101138914 polymer processing method and its device, the inventor integrated the polymer flow path and the force-bearing part of the mold clamping into one injection end piece. Accordingly, when the polymer raw material is heated and injected into the adjacent mold through the injection end piece, it can avoid the lack of coking of the raw material caused by flowing through the existing heating mechanism as in the known technology, and can provide The stress-bearing parts with better strength make the mold clamping work smoothly. [0003] After the injection process of the polymer raw material injected into the mold through the aforementioned flow path is co...

Problems solved by technology

[0003] After the injection process of the polymer raw material injected into the mold through the aforementioned flow path is completed, the polymer raw material remaining in the flow path needs to be cleaned during the change of the injection mark to replace the raw material or the flow path may be damaged due to careless operation. When the clogging occurs, it is necessary to carry out the procedure of clearing the material to avoid affecting the flow of the molten polymer raw material in the subsequent injection procedure. However, since the previous patent disclosure made the flow path of the raw material inside the injection end piece, therefore , the cleaning process is not easy and feasible, and these flow paths are usually channels with a small inner diameter, so when the solidified polymer raw material is drawn out, it is very easy to break and partially solidify The polymer raw materials on the surface remain in the depths of these flow paths, which is not conducive to the smooth operation of the cleaning process
