Problems solved by technology

Among them, dip coating is to immerse the object to be coated in the paint. After all parts are covered with paint, the object to be coated is lifted away from the paint, and the excess paint is dropped back into the trough naturally or forcibly. Form a coating film on the surface of the object to be coated. The dip coating method has the characteristics of high production efficiency, saving paint, uniform coating, low requirements for paint, easy operation, and no special equipment. However, so far, manual dipping is still used. After painting and dipping, workers still need to lift the model, so that the excess paint drips, which is labor-intensive and inefficient

Abstract

The invention relates to machining equipment for a model for lost foam casting. The machining equipment is used for coating the surface of the model with fireproof paint and comprises a rack, a coating groove formed in the bottom of the rack and a conveying assembly arranged on the upper portion of the rack. The conveying assembly comprises a wheel set, a plurality of supporting chain wheels arranged above the wheel set and a conveying chain. The rack is further provided with a motor used for driving any supporting chain wheel to rotate, the wheel set comprises at least one low-position wheelrotationally arranged on the rack, and the conveying chain is wound below the low-position wheel; and hanging frames are arranged on chain links of the conveying chain at intervals, clamping assemblies are arranged on the hanging frames, the clamping assemblies are used for clamping the models, and when the hanging frames move to the low-position wheel, the clamping assemblies extend into the coating groove. The machining equipment has the effects that the models move along with the conveying chain, coating immersing, coating separating and draining are automatically completed, when the equipment operates, the hanging frames are arranged at intervals along the conveying chain, dip-coating of the multiple models is achieved at the same time, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of lost foam casting, in particular to a processing equipment for a model for lost foam casting. Background technique [0002] Lost foam casting (also known as solid casting) is to bond and combine paraffin or foam models similar in size and shape to castings to form a model cluster. After brushing refractory paint and drying, it is buried in dry quartz sand for vibration molding. Bottom pouring, the model is vaporized, the liquid metal occupies the position of the model, and the casting is formed after solidification and cooling. It has the outstanding advantages of high dimensional accuracy, smooth surface, and less pollution. [0003] In the lost foam casting process, it is necessary to apply refractory coatings on the surface of the model. There are generally three methods: brushing, dipping and spraying. Among them, dip coating is to immerse the object to be coated in the paint. After all parts are cov...
