Abstract

A preparation method of a foam product comprises the steps: firstly moving down an upper pressing die to a position with an interval distance of 4-5 mm to a lower molding die; secondarily, automatically feeding to the molding cavity of the lower molding die; after completing feeding, continuously moving down the upper pressing die and tightly locking with the lower molding die; blowing steam downward through inner vent holes of the upper pressing die by a steam system, then blowing steam upward through inner vent holes of the lower molding die by the steam system, and making the steam penetrate the product; heating the upper pressing die and the lower molding die at the same time; after heating, shutting the steam system, making water get into the vent holes of the upper pressing die and the lower molding die via a cooling system for water cooling; and finally after molding, opening the dies and discharging. The preparation method has the advantages of being easy to operate, simple in processing flow, low in cost, clean, environment-friendly, free in raw material waste, free in over high energy consumption and the like.

Description

technical field [0001] The invention relates to a foam product, in particular to a preparation method of the foam product. Background technique [0002] The existing methods for preparing plastic foam products not only have cumbersome processing procedures and high costs, but also increase the risk and are not suitable for industrial production. Contents of the invention [0003] The object of the present invention is to provide a method for preparing foam products that is simple in processing flow, convenient in operation and suitable for industrial production in order to overcome the deficiencies of the prior art. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a preparation method of foam products, comprising the steps of: first moving the upper die down to a space of 4-5mm from the lower forming die; Internal automatic feeding; after the feeding is completed, the upper die continues to go down and then locks o...
