Description

Technical Field

[0001] The utility model belongs to the technical field of extruder die heads, and in particular relates to an extruder die head. Background Art

[0002] Plastic extruders can be matched with various plastic molding auxiliary machines such as pipes, films, braids, monofilaments, flat wires, strapping tapes, extruded meshes, plates (sheets), profiles, granulation, cable wrapping, etc. to form various plastic extrusion molding production lines. Plastic extrusion molding machinery is one of the widely used machines in the plastic processing industry, both now and in the future. The extrusion die is one of the important mechanisms of the extruder. At present, the extruder die heads on the market need to add cooling devices to allow the material to be quickly cooled and formed during discharge to avoid deformation. At the same time, it prevents the device temperature from being too high, causing deformation of the extrusion channel and affecting the service life. However, this type of extruder die cooling device can often only cool the side of the extrusion head close to the extrusion channel, resulting in a shorter cooling channel and insufficient cooling time, which in turn affects the cooling effect.

[0003] Patent application number 202323446931.8 discloses an extruder die head, including an extruder die head, the rear end of the extruder die head is fixedly connected to a feed pipe, the front end of the extruder die head is fixedly installed with an extrusion head, an extrusion channel is provided inside the extruder die head and at the front end of the feed pipe, the top of the extruder die head is fixedly connected to an upper cold air duct, the bottom end of the extruder die head is fixedly connected to a lower cold air duct, the rear end of the lower cold air duct located inside the extrusion channel is fixedly connected to a second branch air flow pipe, the front end of the lower cold air duct located inside the extrusion channel is fixedly connected to a first branch air flow pipe, and an extrusion channel is provided inside the extrusion head and at the front end of the extrusion channel.

[0004] The above technical solution uses multiple ventilation channels and cold air ducts to cool the extruder die head. However, since the temperature of the die head is too low during use, the raw materials will be cooled and solidified before being extruded and formed, resulting in poor extrusion effect of the raw materials and easy solidification and clogging of the extrusion holes.
