An improved casting sand box

Abstract

The invention relates to an improved casting flask, comprising an installation base, a lower flask and an upper flask, the upper end of the installation base is provided with a lower flask, and the upper end of the lower flask is provided with an upper flask which is used in cooperation with each other. The existing sand casting often has the following problems when using the sand box for processing: a: The existing sand box needs to separate the sand box after finishing the pouring and the interval operation, but first, sticking between the upper and lower sand boxes often occurs. The phenomenon occurs, which increases the difficulty of picking up parts and increases the workload of employees; b: the existing sand box needs to be cooled for a period of time after the pouring operation, waiting for the molten metal to cool and form, but because there is a gap between the joint surfaces of the sand box , so the phenomenon of air flow may lead to the rapid cooling of the molten metal in the sand box, which affects the quality of the product.

Description

technical field [0001] The invention relates to the technical field of sand casting, in particular to an improved casting flask. Background technique [0002] Casting is a kind of metal thermal processing technology mastered by human beings earlier. It is a method of casting liquid metal into a casting cavity that is suitable for the shape of the part. It is cheap and easy to obtain, and the casting mold is easy to manufacture. It can adapt to the single-piece production, batch production and mass production of castings. It has been the basic process in casting production for a long time. Now sand casting is often used for sand casting. , but the existing sand box still has certain deficiencies in use. [0003] The existing sand casting often has the following problems when using the sand box for processing: a: The existing sand box needs to be separated after the pouring is completed and the interval operation is performed, but first, sticking between the upper and lower s...
