Geogrid extrusion and fixation device

Abstract

The invention relates to a geogrid processing device, in particular to a geogrid extrusion and fixation device. The geogrid extrusion and fixation device comprises a frame as well as 7 hydraulic mold locking systems, 14 molds, 14 plasticization material buckets, 14 plasticization oil motors and 14 injection oil cylinders which are arranged on the frame, wherein the hydraulic mold locking systems are positioned at the bottom of the frame, an operating table is arranged on the upper surface of each hydraulic mold locking system, and the molds are arranged on the operating tables; and extrusion terminals corresponding to the molds are arranged above the molds, the plasticization material buckets for material supply are connected above the extrusion terminals, the plasticization oil motors for controlling the plasticization material buckets to load material into the extrusion terminals are connected above the plasticization material buckets, and the injection oil cylinders for providing power for the plasticization oil motors are connected above the plasticization oil motors. The material is sequentially loaded above the extrusion terminals, so that the time required for completing material loading 14 times can just effectively prevent the injection molding temperature from being too high, the cost can be effectively saved, and the beautiful appearance of the geogrid can not be affected.

Description

technical field [0001] The invention relates to a processing device for a geogrid, in particular to an extruding and fixing device for a geogrid. Background technique [0002] Plastic geogrid is a square or rectangular polymer mesh formed by stretching. It is punched on an extruded polymer sheet (the raw material is mostly polypropylene or high-density polyethylene), and then in Directional stretching is performed under heating conditions. During the manufacture of the plastic geogrid, the polymer polymers will rearrange and align with the heating and extension process, which strengthens the bonding force between the molecular chains and achieves the purpose of improving its strength. However, its elongation is only 10% to 15% of the original plate, and its durability such as acid resistance, alkali resistance, corrosion resistance and aging resistance needs to be improved. [0003] At present, in order to improve the strength and elongation of the plastic geogrid, the met...

AI Technical Summary

Problems solved by technology

[0003] At present, in order to improve the strength and elongation of the plastic geogrid, the method of one-time injection molding to fix the cross point of the two ribs of the geogrid is now used, but sometimes the overheating of the injection molding time will make the geogrid The ribs are deformed; some of the existing geogrid extrusion fixtures are not successful in one injection molding, and they need to be injected many times, so that the extrusion terminal will also be squeezed out many times, which will affect the appearance of the geogrid, and will also affect the appearance of the geogrid. Increase the cost; the extrusion fixtures of these geogrids have multiple extrusion terminals, and the device will control the feeding to the upper part of the extrusion terminals at the same time, and then at the same time, the material will be extruded from the extrusion terminals and pressed to the corresponding mold of the extrusion terminals In this way, it is impossible to control the material added to the upper part of the extrusion terminal to meet each cross point of the two rib belts of the fixed geogrid
