Problems solved by technology

like figure 1 As shown, there are many longer handles after the product is out of the mold. The reason is that the distance between the end faces 43 of the heated nozzles 42 formed in the static mold 41 and the static mold cavity 44 is relatively long, that is, the gate is relatively long. , when the injection is stopped and the product 45 is cooled, the product 45 moves upward with the movable mold 46, and the

Abstract

A very large plastic injection moulding apparatus is composed of an injection-storage-pre-plasticizing system with multi-nozzle multi-point injection structure, a mould consisting of movable and static moulds and its close mechanism, a press system, a casing safety system, a hydraulic system, an electric controller and a heater for nozzles. Its technology includes such steps as closing mould, injection, cooling, opening mould, and taking product out of the mould.

Description

technical field [0001] The invention relates to plastic injection molding equipment and technology, in particular to ultra-large plastic injection molding equipment and technology. Background technique [0002] At present, the main models of injection molding machines at home and abroad are: horizontal models and single-point injection models. Injection volume 38000cm 3 The above large-scale injection molding machines have defects such as heavy machines, high energy consumption, and high prices. Aiming at the defects of the above-mentioned prior art, the technology in the patent application No.: 02128802.X and 200310107260.0, both titled: "Super Large Plastic Injection Molding Process and Equipment" discloses multi-point compound injection molding super large plastic injection molding equipment. Although the above-mentioned equipment can overcome the defects of the above-mentioned technology, there are many longer handles on the product at the injection point after the pr...
