Matrix type heating temperature control platform device for thermocuring mold

Abstract

The invention discloses a matrix type heating temperature control platform device for a thermocuring mold. The device comprises an upper heating flat plate, a lower heating flat plate, a plurality of groups of heating pipes, a heated mold, a matrix temperature measuring element, a multichannel temperature controller and a multichannel powder module. According to the temperature control platform, the plurality of groups of heating pipes are used for heating the heating flat plates having large areas; the heating flat plates heat the mold in a control range by heat guiding, the matrix distribution type temperature measuring element is adopted for measuring the temperature field of the mold in the mold range, furthermore a special weighting algorithm is adopted for calculating temperature control deviation, and the powder of a heating rod is controlled by the result of the deviation, so that the temperature control accuracy of the mold is within a range of + / -5 DEG C, the temperature difference is less than 5 DEG C in a matrix range, further the production finished products yield is increased, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a thermal control device for ensuring uniform heating temperature with small deviation, in particular to a matrix heating temperature control platform device for thermal curing molds. Background technique [0002] With the speed up of network broadband, more and more users choose fiber-optic access to the home, which leads to an increasing demand for fiber optic cable reinforcement cores. Traditional steel core reinforcement ribs are gradually being replaced by fiber-reinforced resin due to weight and construction process problems. Replaced by FRP reinforced core, the market has put forward higher requirements for the production efficiency of FRP-type optical cable reinforced core. At present, in the production process of fiber-reinforced resin FRP reinforced core, metal molds are widely used for thermal curing after fibers are impregnated with resin. It is the most critical step in production. The curing temperature and curin...

Problems solved by technology

The curing temperature and curing time have a very important impact on the yield and efficiency of production. The traditional temperature control method uses a single point temperature measurement to heat the entire heating area, which often leads to uneven temperature field and temperature changes with time. The range is relatively large, which in turn affects the yield rate and the speed of the production line. At the same time, it also causes the production workers to constantly adjust the temperature control parameters, which is labor-intensive and error-prone.
