Problems solved by technology

Among them, flame heating is prone to local high temperature and has high potential safety hazards; high-temperature steam heating requires an additional high-temperature boiler and the upper limit of heating temperature is low, sometimes it cannot meet the temperature requirements, and sometimes it will oxidize the mold material, affecting the use of the mold Life; when heating with hot water or hot oil, the internal structure of the mold must be arranged with a pipeline circuit for liquid flow, the efficiency is low, and the water and oil need to be pressurized. In addition, the oil is easy to cause pollution, especially for light-colored or no For injection molding products with transparent color, oil pollution will seriously affect the quality of injection molding products; the heating of the heating rod requires modification of the mold structure, and the requirements for the thermal conductivity of the mold material are high, and the power loss rate is high

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a temperature control heating device for an injection molding mold, in particular to an external induction heating device for a vertical injection mold. Background technique [0002] Injection molding is a mature plastic product processing technology, which is widely used because of its high processing efficiency, strong automation, and the ability to form complex shape products. With the progress of the times and the development of science and technology, there are more and more types of plastics to be processed, and the quality requirements of injection products are higher and higher. Therefore, injection molding requires higher and higher parameters such as temperature control and pressure regulation range. Along with it, more and more new technologies are applied to the field of injection molding, among which the variable mold temperature technology is one of the me...
