Problems solved by technology
[0008] According to the above-mentioned technical problems, a nylon rod extrusion die with a sizing die structure is provided, which is used to solve the existing rod extrusion die, which does not guarantee the internal quality of the molded product and the surface quality of the extruded rod is not enough High, and the adjustment of the damping force in the bar extrusion process is also relatively backward, and the manual tightening splint device is used for adjustment, which is time-consuming and labor-intensive, and also takes up space.

Embodiment Construction
[0029] Such as Figure 1 to Figure 3 Shown, a kind of nylon rod extrusion die with calibrator structure, comprises upper die plate 3 and lower die plate 7, is connected and fixed by a plurality of clamping guide pillars 18 between described upper die plate 3 and lower die plate 7, described The two ends of the clamping guide post 18 are locked and fixed with nuts; the upper template 3 is processed with a through hole for one end of the clamping guide post 18 to pass through, and the hexagonal nut 12 is connected with the clamping guide The column 18 is clamped and fixed; the lower template 7 is processed with a through hole for the other end of the clamping guide column 18 to pass through, and is clamped and fixed with the clamping guide column 18 by two hex nuts II17, two The two hex nuts II17 are respectively locked and clamped on both sides of the lower template 7. The hexagonal nut I2 is a Φ39 hexagonal nut, that is, the inner diameter of the nut is 39 mm, and the hexagon...

The invention discloses a nylon bar extrusion die provided with a stock die structure. The nylon bar extrusion die comprises an upper die plate and a lower die pate which are connected and fixed through a plurality of clamping guide columns, and the two ends of the clamping guide columns are matched with nuts for being locked and fixed; a connecting shaft is mounted on the outer side of the upperdie plate, and a die head plate is mounted on the inner side of the upper die plate; an outer thread arranged at the outlet end of the connecting shaft and a central groove hole in the upper die plateare fixed in a threaded mode. According to the nylon bar extrusion die provided with the stock die structure, through a pressurizing section, a finishing section and a resistance reducing section onthe surface of a stock die cavity, the flat and smooth surface and the tight internal structure are formed on a nylon bar product, removing of air hole shrinkage cavities is ensured through the pressurizing section, and thus the internal structure of the nylon bar is more tight; through the finishing section, the outer surface of the nylon bar is smooth and flat, and the roughness is low; and resistance in the extruding process of the nylon bar is reduced through the resistance reducing section, and stability and reliability of extruding moment are ensured.
Description
technical field [0001] The invention relates to the technical field of extrusion molding dies, in particular to a nylon rod extrusion die with a novel calibrating die structure. Background technique [0002] At present, as an important engineering plastic, nylon has extremely excellent comprehensive properties, including high mechanical strength, stiffness, etc., good toughness, wear resistance, electrochemical properties, etc., making it a very versatile plastic. Strong and versatile polymer material. At present, the production process for nylon rods includes static casting method and centrifugal casting method, and there are related patents, but there is no related mold patent for the extrusion molding process suitable for nylon rods. [0003] In order to solve the related technical problems, the Chinese invention patent discloses a rod extrusion die for ultra-high molecular weight polyethylene, the application number is 200910013863.1, and its technical solution is: the ...
