Problems solved by technology
However, the current injection molding method generally adopts the method of screw conveying injection molding or direct pressure rod injection molding. Although the method of screw conveying is convenient and continuous, it is easy to cause dissatisfaction in the mold due to insufficient conveying force during injection molding. There are defects and pores in the product. Although the pressure is easy to control in the direct pressure injection molding method of the pressure rod, the continuity of the injection molding is not good. Because it requires a large stroke of the pressure rod, it is impossible to achieve precise control and precise elimination. gap

The invention discloses a macromolecular reaction injection molding device. A pore elimination mechanism is arranged at the end, far away from an injection molding head, of an injection molding tube,the pore elimination mechanism can apply pressure to slurry in an injection mold after an injection molding pushing mechanism injects macromolecular filler into the injection mold so as to eliminate pores of the slurry in the injection mold and the injection molding tube and improve the quality of products, and the problem of defects or pores of the products, caused by insufficient filling or poorfilling of the mold, can be prevented. According to the device, the special pore elimination structure is adopted, control is accurate, injection molding is continuous, and a part of bubbles can be eliminated when the slurry is still in the injection molding tube.
Description
technical field [0001] The invention relates to the field of injection molding technology, in particular to a polymer reaction injection molding device. Background technique [0002] Injection molding is a technology that injects molten materials into the mold to achieve rapid prototyping. Polymer compounds such as plastics and rubber are generally formed by injection molding. During injection molding, two polymer materials are usually fused together. Polymerization, the performance of the material after polymerization is stronger than that of the two raw materials. However, the current injection molding method generally adopts the method of screw conveying injection molding or direct pressure rod injection molding. Although the method of screw conveying is convenient and continuous, it is easy to cause dissatisfaction in the mold due to insufficient conveying force during injection molding. There are defects and pores in the product. Although the pressure is easy to contro...
