EVA secondary foaming formation method

Abstract

The invention discloses an EVA secondary foaming formation method which adopts an EVA secondary foaming formation system and is characterized in that the EVA secondary foaming formation system comprises a die changing device, a heating device and a cooling device; the heating device is provided with a heating rotary table which can intermittently rotate; the heating rotary table is provided with multiple heating stations which are circumferentially distributed; the cooling device is provided with a cooling rotary table which can intermittently rotate; the cooling rotary table is provided withmultiple cooling stations which are circumferentially distributed; and the die changing device is provided with a die changing rotary table which can intermittently rotate, a heating manipulator usedfor pushing dies on the die changing rotary table into the heating stations or pulling back the dies from the heating stations and a cooling manipulator used for pushing dies on the die changing rotary table into the cooling stations or pulling back the dies from the cooling stations. The EVA secondary foaming formation method provided by the invention can effectively lower the labor intensity andimprove the production efficiency.

Description

technical field [0001] The invention relates to an EVA secondary foam molding method. Background technique [0002] The EVA secondary foaming process needs to put the blank into the mold, then put the mold into the heating device for heating, wait for heating, take out the mold from the heating device after the heating is completed, then put the mold into the cooling device for cooling, and then Take out the mold from the cooling device, and then take out the finished product from the mold; the above processes are all done manually, usually the mold is relatively heavy, and it takes time to wait for heating, and the mold has a certain temperature after heating, which has high labor intensity and potential safety hazards. Low efficiency, poor working environment and other issues. Contents of the invention [0003] The object of the present invention is to provide an EVA secondary foaming molding system with convenient operation, low labor intensity and high production effi...
