Abstract

The invention provides a molding mold for a glass fiber reinforced plastic grate, which comprises a molding template, a temperature control chamber, a warming pipeline, a heat preservation layer and other parts, wherein the temperature control chamber is arranged below or on the lower portion of the molding template, the warming pipeline and the heat preservation layer are arranged in the temperature control chamber, the heat preservation layer is wrapped on the left side, the right side and the lower side of the warming pipeline, and the heat preservation layer is made of inflaming retarding plastics or noncombustible mineral wool. Outlets and inlets of the warming pipeline are arranged below the temperature control chamber, and all the inlets are connected with the same bus pipe which is connected with a temperature measurement instrument. A heat source device is a solar energy device and a conventional coal furnace or oil furnace device which are connected in parallel and respectively connected with a valve A and a valve B. The temperature measurement instrument is connected with a control system through a signal line, and the control system is respectively connected with the two valves and controls opening and closing of the two valves through a control line. The molding mold for the glass fiber reinforced plastic grate adopts a pipeline, heat preservation layer and template integrated design and is compact in structure, good in heat preservation effect and small in energy consumption. In addition, the molding mold can adopt a self-control system and is high in automation degree and production efficiency and low in labor intensity.

Description

technical field [0001] The invention relates to a molding mold for glass fiber reinforced plastics, in particular to a glass fiber reinforced plastic grid molding mold with good energy saving effect and high degree of automation. Background technique [0002] Usually, the forming mold of FRP grating is mainly a flat steel formwork placed under the FRP grating. In order to achieve the temperature required by the forming process, auxiliary heating is often required. The usual heating facilities are installed under the steel formwork. The long hot water pipes arranged in parallel are connected to the hot water boiler (coal furnace or oil furnace). During production and operation, while the hot water pipe provides heat to the FRP grille upwards, it also dissipates a lot of heat to the left, right and downward, resulting in large energy consumption and serious energy waste. [0003] The patent specification No. 02802597.0 applied by Japan Toray Co., Ltd. discloses a "manufacturi...
