Gravity casting mold refers to the process of injecting molten metal into the mold under the action of Earth's gravity, also known as casting mold. Generalized gravity casting includes sand casting, metal casting, investment casting, mud casting, etc; Narrow meaning gravity casting refers to metal mold casting. As an indispensable part of gravity casting technology, the application of gravity casting molds is a relatively frequent mechanical equipment
Factors to pay attention to in the production of gravity casting molds:
As a widely used process technology, gravity casting has a significant demand in many industries, and gravity casting molds are also very popular on the market. It should be noted that in the actual production process of gravity casting, each link must be strictly controlled. Any mistake in any link can cause damage to the quality of the casting or even direct scrapping. Therefore, it is necessary to understand the areas that need to be paid attention to when producing gravity casting molds
1. Preparation for pouring
Before gravity casting, it is necessary to prepare for pouring, which is a prerequisite to ensure the smooth progress of the entire process. The specific preparation work includes cleaning the pouring site and inspecting the quality of the pouring ladle
2. Pouring temperature
In terms of factors that ensure the quality of castings, the pouring temperature is a very core part and also requires strict control. Once the temperature control is not good, it will directly affect the quality of the casting and may also cause the gas to not be discharged smoothly
3. Gravity casting mold
Whether the quality and size of gravity casting molds match the actual production needs of castings is crucial, and strict inspections must be conducted in advance. In addition, correct operating techniques are also an important factor affecting the quality of castings and require strict training
