Embodiment Construction

[0020] Describe in detail below in conjunction with the embodiment of the present invention;

[0021] A metal arc spraying mold process, comprising the steps of:

[0022] The first step, the preparation of the master model:

[0023] The metal spraying master model can be made by RP prototype, or by CNC machining of non-metallic models or direct use of physical samples of panels; for automotive panels, due to their large size and difficult operation, CNC machining of plaster models is used to make them ;

[0024] The water-solid ratio of the gypsum model material is determined through experiments. An appropriate water-solid ratio can make the fluidity, curing strength and hardness of the slurry reach a satisfactory level; in addition, a strengthening agent and a retarder are added to the slurry to improve the gypsum The molding quality of the model; use amyl alcohol as a defoamer to eliminate the air bubbles generated when stirring the gypsum slurry; fix the prototype on the ...

Abstract

The invention discloses a metal arc die spraying technology. The technology comprises the first step of female die preparing, the second step of female surface pretreatment, the third step of metal arc spraying, the fourth step of backing material filling and the fifth step of demoulding and posttreatment. According to the metal arc die spraying technology, the cost is only 1 / 10 of the cost of traditional steel die machining, and the manufacturing period is 1 / 4-1 / 5 of traditional steel die machining. Metal arc die spraying is a rapid die manufacturing method and becomes the rapid and economical main die development direction with high speed, low cost and high performance relative to other rapid tooling. The metal die spraying manufacturing technology is applied to automobile covering parttrial-manufacture dies, and important economic and social benefits are achieved.

Description

technical field [0001] The invention relates to the field of metal arc spraying molds, in particular to a process for metal arc spraying molds. Background technique [0002] The traditional stamping dies for automobile panels are steel dies or cast iron dies, which have a long manufacturing cycle and high cost, and are not suitable for the development of new models and small batch production. With the further development of mold technology, rapid molds such as simple steel molds, resin molds and metal spraying molds are gradually used to replace traditional stamping molds for the development of new models and small batch production. The metal arc spraying mold has low cost, short manufacturing cycle, and good mechanical properties of the mold surface, which provides a new manufacturing method for the rapid manufacture of automobile panel molds. [0003] Metal arc spraying rapid molding technology is a "replication" molding technology. It uses a physical model as the master ...
