Description

Technical Field

[0001] The utility model relates to the technical field of temperature control components, in particular to a pressure and temperature control component for a high-pressure degassing machine. Background Art

[0002] Finished resin products are molded by casting. Because finished resin products have a wide range of uses and low cost, they can be used to make various molds for products with different shapes. Therefore, they are widely used in light and heavy industries. However, during the production process, a large number of bubbles will be generated after the resin and curing agent are stirred and mixed, and the resin has a high viscosity, so bubbles are easily retained in the liquid.

[0003] A Chinese utility model with authorization announcement number CN212440161U discloses a resin degassing temperature control device. When in use, the device is composed of a reactor, a temperature sensor, a heating rod, a stirring rod and other components. When degassing the resin, the resin is stirred by the stirring rod, and the temperature sensor monitors the temperature of the resin in real time. The heating rod is controlled by the temperature controller to heat, maintain temperature balance, and improve the degassing efficiency. However, in specific use, if the shape, size and speed of the stirring rod are not reasonably designed, it may not be able to effectively cover the resin in the entire reactor, resulting in dead corners and stirring blind spots. The resin in these blind spots cannot be effectively degassed, affecting the overall degassing effect. Therefore, it is necessary to redesign a pressure and temperature control component for a high-pressure degassing machine to address the above problems. Utility Model Content
