Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mold heating tubes, in particular to a mold heating tube safety protection device. Background Art
[0002] In the casting production process, casting molds and core boxes are indispensable. The molds and core boxes need to be heated. Generally, a heating tube is added to heat the core box using the electric heating principle. When the heating tube is working, the surface temperature is very high. When dry-burning in the atmospheric environment, attention should be paid to the exposed heating parts to prevent accidents such as short circuits and fires.
[0003] The sand mixture made of casting sand, thermosetting resin and curing agent is injected into a core box with a heating device and heated to 180-250°C to heat the sand close to the surface of the core box. Under the action of temperature, the binder can be polycondensed and hardened in a very short time to form a core. There are currently two methods for heating the core box in the foundry industry, one is electric heating and the other is gas heating. Electric heating is currently more commonly used, but electric heating often causes leakage, fire, short circuit and other phenomena during casting. For this reason, we propose a mold heating tube safety protection device. Utility Model Content
