Automatic vacuum slurry dipping device for precision investment casting and process of automatic vacuum slurry dipping device

Abstract

The invention relates to the technical field of precision investment casting, and particularly discloses an automatic vacuum slurry dipping device for precision investment casting, and a process of the automatic vacuum slurry dipping device. The automatic vacuum slurry dipping device comprises a slurry tank assembly, supporting mechanisms arranged at the left end and the right end of the slurry tank assembly, a sliding mechanism arranged in the middle of the upper end of each supporting mechanism, and lifting mechanisms arranged on the two sides of each sliding mechanism, wherein the sliding mechanism is composed of a sliding plate assembly, a hanging assembly and a sliding driving assembly, and the lifting mechanism is composed of a cover plate lifting assembly and a material frame lifting assembly. According to the invention, an intelligent touch screen is used for controlling an ultrasonic vibrator, an electromagnetic valve I, an electromagnetic valve II, a driving motor, a lifting cylinder I, a lifting cylinder II, an electromagnet and a vacuum pump in a linkage mode to achieve automatic control over all working procedures, and manual intervention is not needed in the process from mold placing and slurry hanging, so that efficiency is high, and controllability is high; and slurry in the whole slurry tank is vibrated by adopting the ultrasonic vibrator, so that the internal activity of the slurry is kept, and the coverage rate of the slurry on the surface of the mold is improved.

Description

technical field [0001] The invention relates to the technical field of investment precision casting, in particular to an automatic vacuum slurry dipping device for investment precision casting and a process thereof. Background technique [0002] In investment casting, in order to ensure that the workpiece and the mold can be released well, it is generally necessary to spray a release agent on the surface of the mold. The comprehensiveness and uniformity of the release agent spraying will affect the quality of the release to a certain extent, thereby affecting the quality of the parts. Surface quality, in the prior art, the surface of the mold is treated with vacuum paste, which improves the labor efficiency to a certain extent and can meet the general use requirements, but it still has the following shortcomings in the actual use process: [0003] 1.

[0002] In investment casting, in order to ensure that the workpiece and the mold can be released well, it is generally necessary to spray a release agent on the surface of the mold. The comprehensiveness and uniformity of the release agent spraying will affect the quality of the release to a certain extent, thereby affecting the quality of the parts. Surface quality, in the prior art, the surface of the mold is treated with vacuum paste, which improves the labor efficiency to a certain extent and can meet the general use requirements, but it still has the following shortcomings in the actual use process:

[0003] 1. The slurry dipping device in the prior art has a narrow operating range, a low degree of automation, lack of precise control links, and the work efficiency needs to be further improved;

[0004] 2. Compared with the large-scale mold coating device in the prior art, the connection between the processes is lagging behind. Compared with mass production, its efficiency needs to be further improved
