Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as Figure 1 to Figure 3 As shown, a mold production process, the specific steps include: blank cutting, milling, grinding, cutting, stress relief treatment, vacuum heat treatment, cutting, water cooling, straightening, storage. Rough cutting cuts the raw material to obtain a mold block suitable for machining. Milling includes primary milling, secondary milling, and tertiary milling; primary milling roughs the surface of the raw material, secondary milling processes forming holes, and tertiary milling finishes the mold. After three milling operations, a mold with a precision that meets the requirements is obtained. At this time, the mold has the required holes and grooves, and then it is ground to make the surface roughness of the mold meet the requirements. The mold is preliminarily completed and the mold at this point is cut to ...

Abstract

The invention discloses a die production technology. The die production technology comprises the specific steps of blank cutting, milling, grinding, cutting, vacuum heat treatment, cutting, water cooling, straightening and storage. Milling is carried out in a milling machine. Grinding is carried out in a grinding machine. Cutting is carried out in a sawing machine. Straightening is carried out ina straightening machine. Vacuum heat treatment is carried out in a vacuum nitriding furnace, and comprises the specific steps of weighing, surface cleaning, classified furnace charging, program setting, quenching, tempering and comprehensive inspection. The die production technology is reasonable in production process, appropriate in cost control and high in percent of pass of products.

Description

technical field [0001] The invention relates to the technical field of mold production and manufacturing, more specifically, it relates to a mold production process. Background technique [0002] Mold is a kind of various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping, stretching and other methods to obtain the required products. There are many types of molds, and each mold has different structures, requirements, and uses, and they all have specific production processes. But for the same type of mold, its production process has common characteristics. The mold mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Therefore, the production of the mold must have a high degree of plasticity, so as to ensure the adaptability of the mold. However, there are certain defects in the current mold production process. ...
