Problems solved by technology

At present, the width adjustment system generally adopts inner or outer stoppers. If the outer stopper is used, there will be material accumulation in the flow channel, and it will be affected by the temperature, which will affect the quality of plastic products after molding. Currently, the inner stopper is used to adjust the effect. It is not ideal, it is easy to leak material, the adjustment of the internal stop is not smooth, it is easy to get stuck, etc., needs to be improved

Abstract

The invention provides a novel inner stop width adjusting structure of an extrusion mold head in the technical scheme. The novel inner stop width adjusting structure comprises an upper mold and a lower mold. A width adjusting mechanism is arranged on the side faces of the upper mold and the lower mold and comprises a large side plate connected to the side faces of the upper mold and the lower moldand three guide rods connected to the large side plate and distributed triangularly. A guide rod fixing block is arranged at the other ends of the guide rods. A stop strip fixing sliding block capable of freely sliding along the guide rods is mounted on the guide rods. An adjusting lead screw is connected to the large side plate. The stop strip fixing sliding block and the adjusting lead screw are in threaded fit to form a lead screw and nut mechanism. A main runner stop strip and a flow stabilization sizing segment stop strip which stretch into discharging runners of the upper mold and the lower mold are connected to the stop strip fixing sliding block. A sealing part is arranged between the main runner stop strip and the flow stabilization sizing segment stop strip and the upper mold and the lower mold. The novel inner stop width adjusting structure is stable in structure, good in rigidity, high in adjusting precision and good in sealing effect.

Description

technical field [0001] The invention relates to an extrusion die head, in particular to a novel inner stop width adjustment structure of the extrusion die head. Background technique [0002] In the field of substrate production and extrusion, a width adjustment device is often used on the extrusion die, which is used to adjust the width of the output of the die lip to meet the requirements of the same die to produce products of different widths. At present, the width adjustment system generally adopts inner stop or outer stop. If the outer stop is used, there will be material accumulation in the flow channel, and it will be affected by the temperature, which will affect the quality of plastic products after molding. Currently, the inner stop is used to adjust the effect. It is not ideal, it is easy to leak material, the adjustment of the inner stop is not smooth, and it is easy to get stuck, etc. It needs to be improved. Contents of the invention [0003] In view of the a...
