Description

Technical Field

[0001] The utility model relates to a shunt structure, in particular to a hot extrusion die shunt structure, belonging to the technical field of insulating component production. Background Art

[0002] Insulation parts refer to components with insulating properties used to isolate or prevent the passage of electric current. They are usually used in electrical and electronic equipment. Insulation parts hot extrusion dies are dies specially used in the hot extrusion process for producing insulation parts. The design of the shunt structure of the insulation parts hot extrusion die needs to take into account the fluidity and forming requirements of the insulation material. Through a reasonable shunt structure, the flow path and speed of the insulation material in the die can be controlled to achieve uniform distribution and precise forming, which helps to avoid defects in the insulation material during the extrusion process, such as folding and cracking.

[0003] In the process of producing insulating parts, when the raw materials are introduced into the connecting position of the feed channel, the raw materials at the connecting part are in contact with the outside air, and there is a temperature difference between the two, which causes the raw materials to become viscous and agglomerate. When the material guide tube is taken out, these agglomerates will be dragged out together, leaving defects in the final product and affecting the quality of the product. At the same time, the raw materials at the connecting part are formed faster during the hot extrusion process, resulting in reduced fluidity, which is not conducive to the production of insulating parts. For this reason, a hot extrusion die diversion structure is proposed. Utility Model Content

[0006] The upper surface of the upper mold is evenly provided with through holes, and a connecting rod is arranged inside the through holes. The connecting rod is slidably connected to the inner wall of the upper mold, and the top of the connecting rod is fixedly connected to the limiting block.

The raw materials are fed into the upper mold through the material guide pipe, and the partition is driven to move by the spring. When feeding, the raw materials push the partition to move to ensure smooth access of the raw materials. After the feeding is completed, the partition closes the feeding channel under the action of the spring, which plays a role of heat preservation and prevents the raw materials from directly contacting the external air, resulting in a decrease in the temperature and fluidity of the raw materials.
