A spraying device and die-casting equipment

Abstract

The invention provides a spraying device and die casting equipment. The spraying device comprises a sprayer, a spraying pipe, a compression mechanism and a feeding pipe. The sprayer is of a hollow cylindrical structure with one end opened and is provided with at least one spraying hole, and the spraying holes communicate with a hollow part of the sprayer. The first end of the spraying pipe is connected with the opening end of the sprayer, the second end of the spraying pipe is connected with the feeding pipe, and the sprayer, the spraying pipe and the interior of the feeding pipe are in communication. The compression mechanism sleeves the feeding pipe and makes contact with the end face of the second end of the spraying pipe. When the compression mechanism recovers to the original state from the compression state, the sprayer, spraying pipe and feeding pipe connected structure can be driven to move in the compression mechanism original state recovering direction. The spraying device does not depend on a push-out mechanism, the safety of a spraying mechanism can be effectively guaranteed, the spraying mechanism is not prone to damage, and the installing position is relatively flexible.

Description

technical field [0001] The invention relates to the technical field of spraying, in particular to a spraying device and die-casting equipment. Background technique [0002] Many auto parts are produced by die-casting, but during die-casting production, the mold sticks to aluminum, which leads to problems such as product drawing and meat loss, which affects the quality of the product. On the existing die-casting machine, the role of the spraying equipment is to The release agent is evenly sprayed on the mold surface to ensure the smooth release of the mold surface and reduce the surface temperature of the mold surface. However, because the mold has many features such as deep cavities, deep ribs, and isolated bosses, the release agent cannot adhere Or the amount of mold release attached is small, so that the heat of these profiles cannot be dissipated quickly. [0003] In view of the above problems, the existing technology is to add a spray pipe structure on the push-out mech...

AI Technical Summary

Problems solved by technology

The expansion and contraction of the spraying mechanism is attached to the push-out mechanism, and the push-out mechanism drives the spraying pipe to move. The moving distance is the push-out stroke (usually between 80 and 100mm), and the unbalanced push-out will easily lead to damage to the spraying pipe.
