Technical Field
[0001] The invention relates to the technical field of heat insulation strip processing, and in particular to a multi-group synchronous extrusion device for nylon heat insulation strips. Background Art
[0002] Nylon insulation strips are made of nylon 66% + 25% glass fiber and other materials, and have the following characteristics: high mechanical strength, can be connected to hardware accessories while bearing tensile shear stress; thermal expansion coefficient is close to that of aluminum profiles, ensuring that the insulation strips and aluminum are closely combined under large temperature differences; high thermal deformation temperature, which can meet the subsequent surface treatment of profiles; high dimensional accuracy, ensuring the airtightness and watertightness of windows; excellent anti-aging and UV resistance, long life; excellent chemical corrosion resistance; nylon insulation strips are mostly used in the field of doors and windows;
[0003] In the production of nylon thermal insulation strips, the material needs to be extruded and shaped into strips. In the prior art, the thermal insulation strips are generally shaped by an extrusion die. However, the shaping holes of the extrusion die are generally fixed apertures. When thermal insulation strips of different specifications are to be produced, the die needs to be replaced, which is troublesome. In the prior art, after the thermal insulation strips are extruded to a certain length, they need to be cut, which is usually done manually by workers.

During the extrusion process, the raw materials are extruded and shaped using the first extrusion hole of a fixed mold and the second extrusion hole of a movable mold. When thermal insulation strips of different thicknesses are required, it is only necessary to use the first pneumatic cylinder to drive the movable mold to move so that the second extrusion hole and the first extrusion hole are staggered by a certain distance, and the caliber of the raw material extrusion is changed, so that thermal insulation strips of different thicknesses can be shaped without changing the mold, which is more convenient.
