Embodiment Construction
[0036] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.
[0037] Such as figure 1 and figure 2 Shown, the present invention relates to a kind of production technology of high-efficiency energy-saving foamed plastics, comprises the steps:
[0038] ① After closing the movable mold 2 and the static mold 3 for shaping the foamed plastic, use the feeder 4 to inject foam material into the cavity between the movable mold 2 and the static mold 3. The upper and lower sides of the cavity An upper air chamber 61 and a lower air chamber 62 are respectively formed, and both the upper air chamber 61 and the lower air chamber 62 communicate with the mold cavity;
[0039] ② Utilize the steam channels communicated with the upper air chamber 61 and the lower air chamber 62 respectively, pass high-pressure steam into the upper air chamber 61 and the lower air chamber 62 respectively ...

Abstract
The productionn discloses a production process and equipment of high-efficiency energy-saving foam plastic, the production process includes the following steps: 1, after die assembly of a moving die and a static die for molding the foam plastic, a foaming material is injected into a mold cavity between the moving die and the static die by use of a feeder, the upper and the lower sides of the mold cavity are respectively formed with an upper gas chamber and a lower gas chamber, the upper gas chamber and the lower gas chamber both are communicated with the mold cavity; 2, high pressure steam is introduced into the upper gas chamber and the lower gas chamber by steam channels respectively communicated with the upper gas chamber and the lower gas chamber, and the pressure is maintained for a period of time, so that the high pressure steam in the upper gas chamber and the lower gas chamber can penetrate into the foaming material from the upper and the lower sides of the mold cavity; and 3, after cooling, the finished product foam plastic is obtained. Compared with the prior art, even if thicker foam plastic is molded, even foaming of the whole foam plastic can be ensured, and the production process can switch to the traditional equipment at any time for forming molding ordinary foam plastic and is very convenient.
Description
technical field [0001] The invention relates to the field of foamed plastics manufacturing, and more specifically relates to a production process and equipment for high-efficiency and energy-saving foamed plastics. Background technique [0002] The applicant once filed a Chinese invention patent application 201110302794.3 with the Patent Office of the State Intellectual Property Office of China on September 30, 2011, which relates to a production process and equipment for thermal insulation bricks. The production process includes the following steps: [0003] ①. Put the porous brick into the container, and fill the brick hole or groove on the porous brick that needs to be filled with thermal insulation material with polystyrene foam particles; the position where the porous brick is set in the container must meet the following conditions: A: Make the part where the polystyrene foam particles are set on the porous brick face the first steam inlet on the container; B: Let the f...
