Vertical film covering device based on V-method casting mold

Abstract

The invention provides a vertical film covering device based on a V-method casting mold. The vertical film laminating device based on the V-method casting mold comprises a portal frame, a heating box is slidably installed on the inner wall of the top of the portal frame, a hydraulic cylinder is fixedly installed at the top of the portal frame, an output shaft of the hydraulic cylinder extends into the portal frame and is fixedly connected with the heating box, and an electric heating wire is fixedly installed in the heating box; a film covering frame is integrally formed at the bottom of the heating box, a heat insulation plate is fixedly mounted on the outer wall of one side of the heating box, a protection box is fixedly mounted on the outer wall of one side of the heat insulation plate, a film roller is rotatably mounted in the protection box, and two suspension arms are fixedly mounted at the bottom of the protection box. The vertical film laminating device based on the V-method casting mold has the advantages that the vertical film laminating device is provided with a film storage structure, related workers can conveniently and rapidly lay a film at the bottom of the film laminating frame on site, and the film is not prone to deformation and damage.

Description

technical field [0001] The invention relates to the technical field of mold casting, in particular to a vertical film coating device based on a V-method casting mold. Background technique [0002] V-method casting is a vacuum-sealed molding method, also known as negative pressure molding method. It uses plastic film to evacuate dry sand to form it. Since no adhesive is used, sand falling is simple, so the consumption of molding materials can be reduced to a minimum. It is very low, and it can also reduce waste sand and improve the surface quality and dimensional accuracy of castings. [0003] In the V-method casting process, covering the model is the initial and relatively important part. The V-method casting film-coating device in the prior art lacks a device that can store the film. On the side of the membrane device, one is that the film is not well protected and is easily polluted, and the other is that it is inconvenient for workers to quickly lay the film on the bot...

[0003] In the V-method casting process, covering the model is the initial and relatively important part. The V-method casting film-coating device in the prior art lacks a device that can store the film. On the side of the membrane device, one is that the film is not well protected and is easily polluted, and the other is that it is inconvenient for workers to quickly lay the film on the bottom of the film frame, which affects work efficiency; in addition, the V method of the prior art casting film The laminating frame and heating box (or heating plate) of the device are designed to be separated. When preheating the film, the laminating frame and the heating box are attached so that the film can be fully and uniformly heated. After the film is heated, The laminating frame is separated from the heating box and covers the model with the film, but the film is easily bonded to the heating box during the heating process, and the film is easily pulled during the process of separating the film from the heating box by the laminating frame, resulting in A large degree of deformation or damage occurs in some areas of the film, resulting in the scrapping of the film
