The invention discloses a polymer extrusion die device capable of changing the shape of the die hole, which is composed of a joystick, a mold back cover, a first die hole component, a second die hole component, a third die hole component and a fourth die hole component . The first, second, third, and fourth die hole components form a hinged four-bar linkage mechanism, wherein the second die hole member is fixed to the mold back cover, and the operating rod is an active part and is connected with the first die hole member. By controlling the swing of the joystick, the first, second, third and fourth die hole components can be driven to change the shape of the die hole. The extrusion die can produce plastic extruded parts with continuously changing cross-sectional shapes, which reduces the production cost of subsequent processing. The invention has important significance in obtaining plastic extruded parts with changing cross-sectional shapes, improving production capacity and reducing processing costs.
Description
technical field [0001] The invention relates to the field of polymer extrusion dies, in particular to a polymer extrusion die device capable of changing the shape of die holes. Background technique [0002] Currently, conventional extrusion processes use a fixed die exit to produce a continuous plastic extrusion product with a fixed cross-sectional shape. The traditional extrusion molding process forms a wide range of product lines. However, since the traditional extrusion process cannot continuously change the cross-sectional shape of the product, the extrusion process has no flexibility to adapt to more and more complex products, and cannot meet the needs of more diverse products. Among them, in the continuous extrusion molding technology, the deformable extrusion die is also a technical field worthy of attention. The deformable mold can not only produce plastic parts with continuously changing cross-sections, but also has the ability that traditional molds do not have, ...
