Abstract

The invention provides a mould with a long glass fiber composite material co-extrusion machine opening. The mould comprises an upper mould and a lower mould, wherein a mould cavity is arranged between the upper mould and the lower mould, a feed opening in butt joint with an extruding machine is processed at one of the sides of the upper mould and the lower mould, a discharge opening is processed in each of the other sides of the upper mould and the lower mould, a long glass fiber introduction plate is arranged in the upper mould, a long glass fiber introduction hole is processed in the long glass fiber introduction plate, a long glass fiber is inserted into the long glass fiber introduction hole, a conveying mechanism is arranged besides the discharge opening, and a cutting device is installed on the conveying mechanism. Compared with the prior art, the long glass fiber is directly introduced into the mould cavity through the introduction hole to reduce the existing heating, plasticizing fusion and cooling process of the long glass fiber, and the length of the long glass fiber can be kept in the extrusion process to a larger extent to reinforce the mechanical property of the material, thereby increasing the building board intensity, saving the energy consumption, shortening the production cycle and reducing the production cost.

Description

technical field

[0001] The invention relates to a co-extruder die with long glass fiber composite material, which is used for the main extruder to extrude the composite material through the die to press various high-strength products, belonging to extrusion molding equipment. Background technique

[0002] At present, in building construction, especially when pouring concrete such as body of wall, beam and square (vertical) column on site, must use a large amount of building templates. Commonly used building formwork mainly includes steel formwork and wooden formwork. The wooden formwork is easy to rot, the use efficiency is low, it is easy to bond with the concrete during use, it is difficult to demould, which brings inconvenience to the construction; the steel formwork is heavy, inconvenient to operate, and easy to rust, the price is high, which increases the construction cost . Therefore, in recent years, some people have developed prefabricated plastic building template...
