No matter what mechanical equipment is used during operation, we need to pay attention to some matters to avoid equipment mistakes, which will affect the operation process. Below, the vacuum pouring equipment manufacturer will introduce to us some matters needing attention during pouring of vacuum oiling equipment. The specific contents are as follows:

During the pouring of vacuum oiling equipment, the flow rate was not adjusted for different molds, and the whole process was poured at a high speed. Perhaps the flow was not well controlled in the process of mold transformation. At the beginning, the flow of castable in the mold was too fast, resulting in too little time to discharge the bubbles. Because the pouring process depends on the experienced operation, the speed of flow rate and the size of flow change with different molds and the viscosity of castables. So far, there is no automatic operation method, and there is a demand for pouring technicians with rich experience.

When the vacuum pouring temperature is too high or the response of the data system is too fast, the service time of the castable is shortened, the viscosity increases, the gas cannot escape from the castable quickly, and moves slowly to the surface in the follow-up process. Therefore, after participating in the curing agent, you can appropriately reduce the system temperature, control the change of data system viscosity, pay attention to the change of temperature, and pour quickly under the appropriate viscosity to ensure that the system viscosity poured into the mold does not change greatly, which can reduce the occurrence of pores.

To protect the casting equipment and pouring mold, we must be careful, patient and step-by-step, and avoid blind engagement. When the formwork is removed due to failure, a material belt shall be attached to facilitate the query of problems. Open the mold, check the mold and confirm the cause of the fault. Find out the problem, and then clean the mold and remove the material scraps before removing the mold. During formwork removal, the force shall be uniform.

Unreasonable mold planning leads to poor cooling effect of pouring port; The gate water bag is not cooled in time, or the size of the water bag is improper or the placement direction is incorrect. Therefore, when planning the mold, it is necessary to scientifically arrange the orientation of the pouring port and cool the orientation and size of the water tank at the pouring port, so that the castable at the pouring port can be fed and shrunk into the mold cavity. When some special shapes cannot be completely solved by the water tank on the mold, a water bag is added, and the size and placement position of the water bag can be adjusted in practical operation. When the pouring temperature is too high or the response of the data system is too fast, the service time of the castable is shortened, the viscosity increases, the gas cannot escape from the castable quickly, and slowly moves to the surface in the follow-up process.
