Electric-drive pull-back type microwave heating foaming forming machine and foaming forming method thereof

Abstract

The invention discloses an electric-drive pull-back type microwave heating foaming forming machine and a foaming forming method thereof. The electric-drive pull-back type microwave heating foaming forming machine comprises a rack, a foaming forming mechanism, a charging basket, a vacuum cooling device, an electric cabinet, a driving motor and a transmission mechanism, wherein the foaming forming mechanism comprises fixed dies, movable dies, fixed die frames, movable die frames and foaming material injection pipes; each fixed die frame and the corresponding movable die frame are combined to form a complete die cavity; each die cavity corresponds to at least one foaming material injection pipe; at least one microwave shielding cover is arranged on each fixed die; at least one microwave shielding cover matched with the microwave shielding cover is arranged on each movable die; the movable die frames and the fixed die frames are made of high-temperature-resistant insulating materials; the fixed dies are positioned between the movable dies and the driving motor; and the driving motor drives the movable dies to move horizontally. According to the electric-drive pull-back type microwave heating foaming forming machine, microwave heating liquid is adopted to generate steam to be matched with foaming plastic for foaming, the structure is simple and compact, the overall size of the foaming forming machine is reduced, the energy consumption is relatively low, no pollution is caused, and the manufacturing and using costs are low.

Description

technical field [0001] The invention belongs to the field of plastic product processing, and in particular relates to an electric drive pull-back microwave heating foaming molding machine and a foaming molding method thereof. Background technique [0002] At present, the foam molding mechanism of the plastic foam molding machine usually uses the steam generated by the boiler or steam generator to send into the mold cavity to cooperate with the foamed plastic injected into the mold cavity for foaming. The boiler or steam generator generates steam on the one hand The structure is relatively complicated, which increases the overall volume of the foam molding machine; on the other hand, the boiler needs to use coal or gas, which not only consumes a lot of energy, but also may cause pollution due to emissions, which increases the cost of production and use. Contents of the invention [0003] In order to solve the defects and deficiencies in the above-mentioned prior art, the pr...
