Problems solved by technology
[0005] Aiming at the difficulty of injection molding in the process of forming large-format special-shaped products from thermoplastic composite materials with poor fluidity (including semi-fluid bulk materials), the required molds and equipment are huge, the price is high, and the existing LFT-D extrusion-molding process is not suitable. It is of great significance to develop a new type of fully automatic online extrusion-compression molding equipment to solve the above problems

Abstract
The invention discloses a metering, cutting and taking device and an automatic online extrusion and mold pressing forming system. The device is mainly composed of a piston; when materials injected into a material storage cylinder reach a certain capacity, the materials in the material storage cylinder are extruded out together by the piston; and due to the device, materials poor in fluidity cannot adhere to the inner wall of the material storage cylinder, quantifying is precise, and the forming precision can be high. The system comprises an extruding machine, a conveying device, a robot material taking device, a mold pressing machine, a robot product taking device and the metering, cutting and taking device, wherein the extruding machine, the conveying device, the robot material taking device, the mold pressing machine and the robot product taking device are sequentially arranged. By means of the system, the process, from the materials to forming, of products is continuous, the metering, cutting and taking device is used so that quantifying can be precise, control is easy, and the formed products meet the design requirement; and furthermore, a programmable logic controller can be used for control, and continuity and high automation in the forming process of the products are achieved.
Description
technical field [0001] The invention relates to a molding device, more specifically, to a metering and cutting device and an automatic online extrusion and molding system equipped with the device. Background technique [0002] The molding and processing methods of thermoplastic polymer composite materials mainly include extrusion molding and injection molding. Extrusion molding products are profiles with the same cross section, and injection molding molding products can be special-shaped products with complex shapes. For thermoplastic polymer composite materials, the thickness of injection molded products directly affects the molding cycle and product quality, so the fluidity of the composite materials used for injection molding must be good. For products with a large format, if injection molding is used, it is necessary to use a large-tonnage injection molding machine, and the investment in equipment is extremely high. [0003] The rapid development of thermoplastic compos...
