At present, most of the main machine factories of mechanical equipment manufacturing still do not have the requirement of internal stress index of casting, because it is relatively difficult to detect the internal stress of casting in technology, and in order to compete in the market, the production cost should be considered, and the casting is scrapped only when it is cracked or deformed due to internal stress. However, since the internal stress of casting is not only temporary, but also has a long-term impact on the performance of casting, the size of the internal stress of casting is required by high-end equipment main machine factory, and some even design unique structure to utilize the internal stress of casting to improve the rigidity of parts. However, as a professional casting enterprise, the internal stress of casting should be minimized in the design of casting process and casting production process, so as to improve the precision stability of parts after installation. There are many factors affecting the internal stress of casting, such as the shape and size of ingate, the structure shape of casting, alloy composition, pouring temperature of molten metal, casting mold material and heat conductivity, sand core retreatability, opening box time, heat treatment and so on. Among them, the shape of ingate has the most outstanding influence on the internal stress of casting, and the shape of ingate plays a crucial role in the quality of casting.

[0004] The above patent document has the beneficial effect of avoiding the disadvantage of increasing the internal stress of wallboard casting when the traditional linear ingate of textile machine wallboard shrinks, but the ingate structure is generally exposed to the outside at the initial stage of casting solidification, and the temperature of the outside is mostly unstable. The internal stress caused by the sharp change of temperature can cause damage to the casting. And the casting does not have a supporting device during solidification and cooling process, which is easy to deform due to its own weight, resulting in internal stress. UTILITY MODEL CONTENTS
