Problems solved by technology

Raw materials for injection molding machines need to be prepared by extruders, and the prepared materials are sent to the injection molding section. In this way, the secondary plasticization of materials not only consumes energy (about 0.22-0.27KW / kg per processing), but also affects the performance of materials. decline

Abstract

The invention discloses continuous mixing and injection moulding equipment. The equipment comprises a mixing and plasticizing device (10) and injection moulding devices (20), wherein the mixing and plasticizing device (10) comprises a casing (101) and a screw arranged inside the casing (101), and a charging port is formed in one end of the casing (101); the injection moulding devices (20) comprise a first injection head (201), a second injection head (202), a first injection power device (203) and a second injection power device (204), the first injection power device (203) and the second injection power device (204) are used for providing power for the first injection head (201) and the second injection head (202) respectively, the first injection head (201) and the second injection head (202) are communicated with the charging port through a pipeline, a first unidirectional control switch (40) is arranged between the first injection head (201) and the charging port, and a second unidirectional control switch (50) is arranged between the second injection head (202) and the charging port. According to the continuous mixing and injection moulding equipment, uninterrupted work of the equipment is realized; and the two injection heads are adopted, so that alternate conduct of charging and injection moulding is realized. The equipment has the advantages of operation continuity, high efficiency, low energy consumption, low cost, simple structure and the like.

Description

technical field [0001] The invention relates to the technical field of plastic molding processing, in particular to a continuous mixing injection molding equipment. Background technique [0002] At present, in the technical field of plastic product preparation, extruders and injection molding machines need to be used. Among them, the twin-screw extruder is the most effective and advanced equipment for preparing new materials with different requirements and uses. It prepares a variety of new materials through the dispersion and mixing of different types, different quantities and different proportions of limited basic raw materials. [0003] For example, by mixing plastics and fibers (such as glass fibers, carbon fibers, steel whiskers, etc.), the strength and stiffness of materials can be improved to prepare so-called reinforced materials; by mixing plastics with inorganic minerals (such as CaCO3, talc, mica, etc.) , can improve the modulus of the material, reduce the cost,...
