Description

Technical Field

[0001] The utility model provides a die head component for an extruder, belonging to the technical field of die heads for extruders. Background Art

[0002] An extruder is a type of production equipment used to extrude materials into strips or specific shapes. It is widely used in industries such as food processing, plastic products, and ceramic manufacturing. An extruder usually consists of a feeding device, an extrusion screw, a heating system, and a mold. By controlling the temperature and pressure of the material, it ensures that the extruded strip products have uniform size and good molding effect.

[0003] The die assembly of the extruder is a vital part of the extruder. It determines the shape, size and quality of the extruded material. The design and performance of the die assembly directly affect the quality of the final product and production efficiency. However, the die of the current extruder is easily clogged by impurities or incompletely melted particles in the material, resulting in poor extrusion or uneven material extrusion. In addition, the structure of the die assembly is complex and difficult to disassemble and clean. When the die assembly is severely worn or needs to be replaced, the replacement cost is high. The design of traditional die assemblies is often limited to specific extrusion shapes and sizes, and it is difficult to adapt to diverse product requirements. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the current die head is prone to poor extrusion or uneven material extrusion during use, is difficult to disassemble and clean, and has a high replacement cost.

[0005] In order to solve the above problems, the utility model proposes the following technical solutions: an extruder die assembly, comprising a lower die seat, the upper end of the lower die seat is threadedly connected to the upper die seat, the upper end of the upper die seat is threadedly connected to the die head, the internal thread of the die head is equipped with a die needle, the upper part of the die needle is slidably equipped with a die core, the upper part of the die core is provided with a lower die needle connector passing through the die head, and the upper part of the die core is provided with an upper die needle connector threadedly connected to the lower die needle connector.

[0006] Beneficial effects of the utility model:

[0007] The device extrudes materials evenly, and the threaded connection of each component makes it easy to disassemble and clean, and can be replaced individually as needed, which reduces replacement costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] according to Figure 1 —As shown in 17: The utility model provides an extruder die assembly: including a lower die seat, the upper end of the lower die seat is threadedly connected to the upper die seat, the upper end of the upper die seat is threadedly connected to the die head, the internal thread of the die head is installed with a die needle, the upper part of the die needle is slidably installed with a die core, the upper part of the die core is provided with a lower die needle connector passing through the die head, and the upper part of the die core is provided with an upper die needle connector threadedly connected to the lower die needle connector; the material of this device is extruded evenly, and the threaded connection of each component makes it easy to disassemble and clean, and can be replaced individually as needed, so that the replacement cost is low.

[0027] The principle of this utility model is: when in use, first install the device on the extruder, and then start the extruder. When the material is extruded from the device, it is relatively uniform. When it needs to be disassembled and cleaned, the threaded connections of each component are convenient for workers to operate, and can be replaced individually as needed, so that the replacement cost is low.
