Problems solved by technology
[0002] When the plastic extrusion mold is cooling and shaping the extruded product, it needs internal cooling through the tail mandrel and external cooling through the water jacket. The existing cooling method for the tail mandrel is to use the pressure plate blowing cooling method. This way, The cooling speed is slow and the cooling effect is poor, and the waterway setting on the water jacket is relatively simple, and it cannot be equidistantly arranged around the extrusion cavity for cooling, so the cooling effect is not good

Description
technical field [0001] The invention relates to a plastic extrusion die, in particular to a high-efficiency built-in circulating cooling system die. Background technique [0002] The plastic extrusion die needs to be cooled internally by the end mandrel and externally cooled by the water jacket when the extrusion product is cooled and shaped. The cooling speed is slow, and the cooling effect is poor, and the water channel setting on the water jacket is relatively simple, and cooling cannot be performed at equal distances around the extrusion cavity, so the cooling effect is also poor. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a high-efficiency built-in circulating cooling system mold with compact structure, good cooling effect, safety and reliability, low cost and long service life. [0004] In order to achieve the above purpose, the present invention includes a mold body, a long screw, a transition plate, a bracket plate, a brac...
