Description

Technical Field

[0001] The utility model belongs to the technical field of V-method casting coating equipment, in particular to a V-method casting horizontal automatic coating device. Background Art

[0002] The biggest advantage of V-method casting over traditional sand casting is that it does not use adhesives. V-method casting uses plastic film to seal the sand box, and relies on a vacuum exhaust system to extract the air in the mold. There is a pressure difference between the inside and outside of the mold, which makes the dry sand dense and forms the required cavity. After core setting, box closing, pouring and vacuuming, the casting solidifies, the negative pressure is released, and the molding sand collapses to obtain the casting. At present, before V-method casting, manual lamination is required on the mold, which affects the processing efficiency. Moreover, since most molds are irregular inside and it is difficult to fully ensure the fit and coverage, which affects the processing accuracy, the horizontal automatic laminating device for V-method casting has attracted more and more attention from researchers.

[0003] Under the existing technology, V-method casting requires manual coating on the mold. Most molds have irregular interiors, making it difficult to fully ensure the fit between the film and the inside of the mold. In addition, a large amount of tape is required to manually stick the film to prevent it from falling off, affecting the processing speed and wasting resources. Utility Model Content

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0033] like Figure 1-9 As shown, the V-method casting horizontal automatic laminating device includes a base 100, a lifting platform 200, a heating box 300, a heating plate 400, an electric control device 500 and an air pump 600. The lifting platform 200 is evenly and movably installed with lifting columns 201, one end of which is installed on the top of the base 100. The height of the lifting platform 200 can be adjusted by the lifting columns 201; the heating box 300 is installed on the top of the lifting platform 200, and the heating box 300 is used to heat the film required for lamination. The corresponding position on the top of the lifting platform 200 is a hollow part. The hollow part facilitates the film to fall downward after being heated and softened; the heating plate 400 is in the shape of a rectangular frame, hollowed out in the middle, and lifting blocks 401 are installed on the four corners of the bottom. The heating plate 400 can be moved up and down by the lifting blocks 401. A plurality of mounting grooves are provided on the surface of the base 100, and a plurality of lifting blocks 401 are plugged into the mounting grooves. A positioning plate 402 is installed on the top surface of the base 100. The top of the positioning plate 402 is used to place the mold to be coated, and the positioning plate 402 matches the hollow part of the heating plate 400; the vacuum pump 600 is installed on one side of the top of the base 100.

[0034] like Figure 1 As shown, load-bearing blocks 101 are evenly arranged at the bottom of the base 100, a ramp 102 is arranged on one side of the base 100, and supporting ears are symmetrically arranged on both sides of the ramp 102. The ramp 102 is fixed to one side of the base 100 by installing reinforcing bolts 103 on the supporting ears and threading them on one side of the base 100. By setting the ramp 102, the purpose of conveniently transporting the mold to the base 100 is achieved.

[0035] like Figure 1 As shown, a lifting slot 202 is installed at the position of the lifting platform 200 corresponding to the lifting column 201, and the lifting column 201 is inserted into the lifting slot 202. An indicator light 203 is also provided on the top of the lifting slot 202. By setting the indicator light 203, the purpose of prompting the lifting platform 200 to be lifted and lowered is achieved.

[0036] like Figure 1 and Figure 8 As shown, a top cover 301 is provided on the top of the heating box 300, a handle 302 is provided on the top of the top cover 301, and a rotating shaft is symmetrically and evenly provided on the side wall of the hollow part of the lifting platform 200, and a rotating plate 303 is installed on the rotating shaft. By setting the rotating plate 303, the purpose of controlling the release of the film is achieved.

[0037] like Figure 1 and Figure 6 As shown, the size of the positioning plate 402 is smaller than the inner frame size of the heating plate 400, so that when the heating plate 400 moves up and down, it is not affected by the positioning plate 402. At the same time, when the heated and softened film is covered on the mold, moving the heating plate 400 downward can make the edge of the film squeezed by the heating plate 400 and slowly fit with the surface of the positioning plate 402, thereby facilitating subsequent operations. In addition, the positioning plate 402 can be freely disassembled. By setting the positioning plate 402, the purpose of connecting the film is achieved.

[0038] like Figure 1 , Figure 2 and Figure 5 As shown, the electric control device 500 is installed on the top of the lifting platform 200. A display screen 501, a control button 502 and a signal receiver 503 are respectively installed on the electric control device 500. By setting the signal receiver 503, the purpose of remotely controlling the laminating device system is achieved.

[0039] like Figure 6 and Figure 8 As shown, a fan 601 is installed inside the vacuum pump 600, a slide groove 602 is provided on one side of the vacuum pump 600, a telescopic probe 603 is slidably connected in the slide groove 602, a fixed groove is opened on the surface of the corresponding side of the heating plate 400, and the telescopic probe 603 matches the fixed groove. By setting the telescopic probe 603, the purpose of inserting the film to extract gas is achieved.

[0040] Working principle: When in use, the laminating device is started by the control button 502 on the electric control device 500, and the laminating device can be remotely controlled by the remote controller in cooperation with the signal receiver 503. The temperature of the heating box 300 and the heating plate 400 can be adjusted according to the display screen 501. The height of the lifting platform 200 is controlled by controlling the lifting column 201 to extend and retract from the lifting slot 202. The lifting platform 200 is lowered, the top cover 301 is opened, and the film is placed inside the heating box 300. The lifting platform 200 is then raised to place the mold on the upper surface of the positioning plate 402, and the heating box 300 is started to soften the film. After softening, the plate is rotated. 303 is turned on to make the film fall down and cover the mold. At this time, the heating plate 400 descends through the lifting block 401 to fit the edge of the film, heats and melts the film so that it slowly fits and adheres to the positioning plate 402. After adhesion, the telescopic probe 603 extends through the fixed groove and is inserted into the film. The vacuum pump 600 is started to extract the internal gas to make it vacuum so that the film fits the mold surface. After the extraction is completed, the telescopic probe 603 retracts and the user can use tape to stick the insertion port to prevent air leakage. After the operation is completed, the operator can remove the mold together with the positioning plate 402 from the base 100 and place a new positioning plate 402.

[0041] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
