Nut casting die

Abstract

The invention belongs to the technical field of mechanical equipment and discloses a nut casting die. The nut casting die comprises a die body. The die body comprises an upper cavity and a base which are integrally formed. The nut casting die is simple in structure. The appearance of the die is manufactured through the resin sand molding process. Due to the fact that resin sand is high in strength, a cast casting cannot expand in a box, manual grinding operation is avoided, casting cost is saved, the size of the appearance of the casting is controlled within 1.5 mm, the stable size of the casting is guaranteed, the yield is high, the production speed is high, grinding is not needed, labor is saved, and efficiency is greatly improved.

Description

technical field [0001] The invention relates to a mold, in particular to a nut casting mold, which belongs to the technical field of mechanical equipment. Background technique [0002] Nuts are also called nuts. They are parts that are screwed together with bolts or screws for fastening. They are a kind of parts that must be used in all manufacturing machinery. They are widely used. According to different materials, they are mainly divided into carbon steel, There are several types of stainless steel and non-ferrous metals, and the nut mold is a tool used to shape the nut. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material, and makes the blank into a specific shape under the action of external force. And size nuts, therefore, nut molds are widely used and are important tools for mass production of nuts. [0003] However, with the gradual use of nut molds, some of its deficiencies are constantly emerg...

Problems solved by technology

[0003] However, with the gradual use of nut molds, some of its deficiencies are constantly emerging. When the existing nut molds are in use, the outer mold cavity is generally one out of two aluminum molds, and the manual molding process, which causes the shape strength of the mold Low, the casting is easy to expand after casting, and the external dimension is difficult to control within 1.5mm, which greatly affects the casting effect and casting quality of the casting. Manual grinding is completed, resulting in a great waste of manpower and material resources, and the number of such molds is small, the production efficiency is low, it is time-consuming and laborious, and the comprehensive economic benefits of nut casting are low. Therefore, we propose a nut casting mold
