Foam molding machine and foam molding method thereof

Abstract

The invention proposes a novel foam forming machine and a foam forming method. The machine comprises a frame; the frame is provided with a feeding system, a mold mounting mechanism, a steam heating system, a cooling water system, a demolding mechanism and an electric automatic control system; the mold mounting mechanism includes a fixed template and a movable template; the movable template and the fixed template are arranged on the same one horizontal line; an oil cylinder drives the movable template to move left and right on the frame to form an opening / closing structure with the fixed template; the movable template and the fixed template are respectively communicated with the steam heating system and the cooling water system; and the demolding mechanism is behind the fixed template. The foam forming machine can adapt to molds with different sizes, and the movable template is connected with a composite material plate and a stainless steel plate layer, so that the equipment use performance at high temperature is improved; and the foam forming machine has the advantages of low mold investment, generality of semi-automatic and full-automatic mechanical molds, convenience to change the molds, high production flexibility and low manual dependence.

Description

technical field [0001] The invention relates to the technical field of foam molding equipment, in particular to a novel foam molding machine and a foam molding method thereof. Background technique [0002] Foam molding machine is a kind of equipment with relatively mature technology. It is used to fill foam particles into molds and heat and pressurize steam to form foam boxes. There are two types of foam molding machines, including semi-automatic molding machines and automatic molding machines. The advantages of using semi-automatic molding machines are that the investment in equipment and molds is small, and the production flexibility is high, but there are slow speeds, high energy consumption, high dependence on labor, unsafe and hidden dangers of mechanical crushing; the advantage of automatic molding machines is that they are fast , relatively energy-saving, low labor dependence, but equipment and mold investment is large, time-consuming and labor-intensive mold change, ...

[0002] Foam molding machine is a kind of equipment with relatively mature technology. It is used to fill foam particles into molds, and heat and pressurize steam to form foam boxes. There are two types of foam molding machines, including semi-automatic molding machines and automatic molding machines. The advantages of using semi-automatic molding machines are that the investment in equipment and molds is small, and the production flexibility is high, but there are slow speed, high energy consumption, high dependence on labor, unsafe and hidden dangers of mechanical crushing; the advantage of automatic molding machines is that they are fast , relatively energy-saving, low labor dependence, but equipment and mold investment is large, time-consuming and labor-intensive mold change, low production flexibility; at the same time due to labor shortages, rising energy costs, small and medium-sized foam factories are facing greater pressure to transform and upgrade, facing two The advantages and disadvantages of the machine are difficult to decide, and the original mold cannot be used universally. To upgrade the fully automatic machine, the mold needs to be re-opened, and the upgrade cost is huge.
