This application relates to a vacuum drying apparatus for highly consistent film formation, comprising a housing with a sealed processing chamber inside; a negative pressure component connected to the processing chamber via multiple air extraction ports; and a flow equalization component located at the top inner edge of the housing for equalizing the airflow generated by the negative pressure component. The flow equalization component includes multiple flow equalization plates, each with multiple uniformly distributed flow equalization grooves on its top surface, and multiple through-hole air extraction holes at the bottom of each groove. Multiple flow equalization plates are stacked sequentially, with the top plate of the stack pressed against the top inner edge of the housing. Multiple air extraction holes on the upper flow equalization plate are connected to multiple flow equalization grooves on the lower flow equalization plate. This application utilizes the flow equalization component to perform multi-layer flow equalization and stabilization treatment on the high-speed, concentrated airflow before applying it to the processing chamber. This ensures the uniformity of the airflow on the film surface while maintaining the extraction rate, and the airflow is gentler, thus ensuring consistent film formation and improving film quality.

The invention discloses a simulation calculation method and device for sand core gas generation, electronic equipment and a storage medium, the method and device are applied to the electronic equipment, and specifically, initial and boundary conditions set by a user are received in response to a setting request of the user; calculating the initial and boundary conditions based on a discrete control equation obtained by processing a preset gas production diffusion control equation to obtain a gas production rate; and calculating according to the gas production rate to obtain the gas generation pressure and speed of the sand core. According to the scheme, simulation calculation of sand core gas generation can be achieved, a data basis is provided for further simulating the processes of gas accumulation, diffusion, casting entering and the like in the sand core casting process, people can conveniently explore the mechanism of gas hole generation and the influence on the casting process, and therefore theoretical support and prediction are provided for reducing the influence of sand core gas generation on the casting product performance; and a casting manufacturer is effectively helped to improve the percent of pass of castings.
