A special spraying device suitable for die-casting equipment

Abstract

The invention relates to the field of die-casting technology, and discloses a special spraying device suitable for die-casting equipment, including a mold frame, a mold cavity is opened on the top of the mold frame, and four channels communicating with the mold cavity are symmetrically opened on the top of the mold frame. The four through slots are equipped with a spraying mechanism, and the mold cavity is also equipped with a sewage discharge mechanism. The four corners of the bottom of the mold frame are fixedly connected with supporting feet. The spraying mechanism includes multiple nozzles and multiple movable plates. The plates are arranged in cooperation with the four through grooves respectively, and the side wall of the movable plate on the side facing the mold cavity is flush with the opening on one side of the through groove, and the side walls on the side of the four movable plates facing away from the mold cavity are all fixedly connected. There is a fixed plate, which is suitable for the special spraying device of die-casting equipment, which can spray from the inside of the mold frame, reduce the waste of release agent, and can make the bottom to top of the die-casting part contact with the release agent evenly, thereby improving the release agent. The effect of the mold, and can facilitate the recovery and cleaning of the release agent.

Description

technical field [0001] The invention relates to the technical field of die casting, in particular to a special spraying device suitable for die casting equipment. Background technique [0002] The die-casting machine is a series of industrial casting machines that hydraulically inject molten metal into the mold under pressure to cool and form it, and obtain solid metal castings after the mold is opened. It was originally used for die-casting characters. With the advancement of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles and household appliances, die-casting technology has developed extremely rapidly in various aspects. [0003] At present, due to the cooling shrinkage of die-casting parts, it is not easy to demould, so that the demoulding of die-casting parts is relatively slow. Therefore, it is necessary to spray a release agent on the surface of the mold cavity every time the die-casting i...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a special spraying device suitable for die-casting equipment, capable of spraying from the inside of the mold frame, reducing the waste of release agent, and enabling the bottom to top of the die-casting to be uniformly aligned with the The mold release agent is in contact with each other, thereby improving the effect of mold release, and can facilitate the recovery and cleaning of the release agent. The outside of the mold frame causes unnecessary waste, and cannot make the release agent better contact with the bottom of the die-casting, which in turn affects the demoulding effect of the die-casting, which is not convenient for people to use
