Description

Technical Field

[0001] The utility model relates to the technical field of pulp metal felt, in particular to a metal felt used for pulp molding. Background Art

[0002] Pulp metal felt is a filter material with a special structure. It combines the high temperature resistance and corrosion resistance of metal fiber with the filtering performance of pulp. The pulp metal felt is generally placed on the surface of the aluminum alloy lower die base. The metal felt is directly fitted with the inner cavity of the aluminum alloy lower die base. The metal felt in the prior art is generally a whole. During the use of such a metal felt, if a certain area is punctured by foreign objects or deformation occurs that affects normal use, the metal felt needs to be replaced as a whole. This has a high cost and causes material waste. Utility Model Content

[0003] Therefore, the purpose of the utility model is to provide a metal felt for pulp forming, which forms an assembled combination structural design through the cooperation of the metal felt limiting frame assembly and the metal felt assembly. When the metal felt in a certain area is deformed and affects its use, the metal felt sheet in the corresponding position can be directly replaced. This does not require overall replacement, thereby reducing the cost of use. In addition, when the metal felt frame is fitted into the aluminum alloy lower mold base, it is directly adsorbed to avoid the situation where the metal felt limiting frame is lifted and displaced when the aluminum alloy upper mold base moves upward.

[0004] In order to solve the above technical problems, according to one aspect of the utility model, the utility model provides the following technical solution: a metal felt for pulp molding, comprising:

[0005] A metal felt limiting frame assembly, the metal felt limiting frame assembly comprising a set metal felt limiting frame, a top frame annular plate fixed on the top of the metal felt limiting frame, and a bottom frame fixed on the inner bottom surface of the metal felt limiting frame;

[0006] A metal felt assembly, the metal felt assembly comprising an arc-shaped opening opened at the inner frame position of the metal felt limiting frame, a side frame metal felt sheet inserted into the arc-shaped opening, a base circular opening opened on the bottom surface of the bottom frame, and a base metal felt sheet inserted into the base circular opening.

[0007] As a preferred solution of the metal felt for pulp molding described in the utility model, there are a plurality of arc-shaped openings, and a corresponding side frame metal felt sheet is clamped in each arc-shaped opening.

[0008] As a preferred solution of the metal felt for pulp molding described in the utility model, the metal felt assembly also includes an annular groove opened on the bottom surface of the top frame annular plate and an annular magnet sheet inserted into the annular groove.

[0009] As a preferred solution of the metal felt for pulp molding described in the utility model, the bottom surface of the annular magnet sheet is flush with the bottom surface of the top frame annular plate.

[0010] As a preferred solution of the metal felt for pulp molding described in the utility model, it also includes a separation component, which includes a circular hole opened at the top end of the top frame annular plate, a spring fixed in the circular hole and a cylinder connected to the top end of the spring.

[0011] As a preferred solution of the metal felt for pulp forming described in the utility model, there are a plurality of circular holes, and the plurality of circular holes are distributed in an annular manner;

[0012] Wherein, each circular hole is provided with a corresponding spring and a cylinder.

[0013] Compared with the prior art, the advantages of the utility model are:

[0014] 1. The utility model forms an assembled combined structural design through the cooperation of the metal felt limit frame assembly and the metal felt assembly. In this way, when the metal felt in a certain area is deformed and affects its use, the metal felt sheet in the corresponding position can be directly replaced. In this way, there is no need to replace the entire piece, which reduces the cost of use. In addition, when the metal felt frame is fitted into the aluminum alloy lower mold base, it is directly adsorbed to avoid the situation where the metal felt limit frame is lifted and displaced when the aluminum alloy upper mold base moves upward.

[0015] Second, based on the first beneficial effect, by setting up the separation component, the spring recovers its deformation during the upward movement of the aluminum alloy upper mold, further promoting the separation of the metal felt limit frame and preventing the metal felt limit frame from being driven by the aluminum alloy upper mold.

[0016] During specific use, the user fits the metal felt limiting frame into the inner cavity of the aluminum alloy lower mold group, and fits several base metal felt sheets into the arc-shaped opening, and fits the base metal felt sheet into the circular opening of the base, so as to form a whole piece of metal felt sheet. In this way, when a certain piece of metal felt sheet is deformed and damaged, the operator can take out and replace the metal felt sheet at the corresponding position without replacing the whole piece of metal felt. When the metal felt limiting frame is fitted into the inner cavity of the aluminum alloy lower mold group, the annular magnet sheet is directly adsorbed to the top surface of the aluminum alloy lower mold base to avoid the metal felt limiting frame being driven to shift.

[0026] The utility model provides a metal felt for pulp molding, which forms an assembled combined structural design through the cooperation of a metal felt limiting frame component and a metal felt component. When the metal felt in a certain area is deformed and affects its use, the metal felt sheet at the corresponding position can be directly replaced. In this way, there is no need to replace the entire felt, thereby reducing the cost of use. In addition, when the metal felt frame is fitted into an aluminum alloy lower mold base, it is directly adsorbed to avoid the situation where the metal felt limiting frame is lifted and displaced when the aluminum alloy upper mold base moves upward. Example

[0027] Figure 1 , Figure 2 The utility model is a schematic diagram of the overall structure of a metal felt for pulp molding. Figure 1 , Figure 2 The main structure of this embodiment includes: a metal felt limiting frame assembly and a metal felt assembly.

[0028] The metal felt limiting frame assembly is used in conjunction with the metal felt assembly. Specifically, the metal felt limiting frame assembly includes a set metal felt limiting frame 11, a top frame annular plate 12 fixed to the top of the metal felt limiting frame 11, and a bottom frame 13 fixed to the inner bottom surface of the metal felt limiting frame 11;

[0029] During specific use, the metal felt assembly is installed and used based on the metal felt limiting frame 11 , the top frame annular plate 12 and the bottom frame 13 .

[0030] The metal felt assembly is used to form an assembled structure, which is convenient for single-piece replacement. Specifically, the metal felt assembly includes an arc-shaped opening 21 provided at the inner frame position of the metal felt limiting frame 11, a side frame metal felt sheet 22 inserted into the arc-shaped opening 21, a base circular opening 23 provided on the bottom surface of the bottom frame 13, and a base metal felt sheet 24 inserted into the base circular opening 23. The metal felt assembly also includes an annular notch 25 provided on the bottom surface of the top frame annular plate 12 and an annular magnet sheet 26 inserted into the annular notch 25.

[0031] During specific use, the user fits the metal felt limiting frame 11 into the inner cavity of the aluminum alloy lower mold group, and fits several base metal felt sheets 24 into the arc-shaped opening 21, and fits the base metal felt sheet 24 into the base circular opening 23, so as to form a whole piece of metal felt sheet. In this way, when a certain piece of metal felt sheet is deformed and damaged, the operator can take out and replace the metal felt sheet at the corresponding position without replacing the whole piece of metal felt. When the metal felt limiting frame 11 is fitted into the inner cavity of the aluminum alloy lower mold group, the annular magnet sheet 26 is directly adsorbed onto the top surface of the aluminum alloy lower mold seat to prevent the metal felt limiting frame 11 from being driven to shift. Example

[0032] Please refer to Figure 3By setting the separation component, the spring 32 recovers its deformation during the upward movement of the aluminum alloy upper die, further promoting the separation of the metal felt limiting frame 11, and preventing the metal felt limiting frame 11 from being driven by the aluminum alloy upper die;

[0033] Specifically, it also includes a separation component, which includes a circular hole 31 opened at the top of the top frame annular plate 12, a spring 32 fixed in the circular hole 31, and a cylinder 33 connected to the top of the spring 32;

[0034] When the aluminum alloy upper mold is pressed downward, the cylinder 33 and the spring 32 are compressed into the circular hole 31. When the aluminum alloy upper mold moves upward and separates from the aluminum alloy lower mold, the spring 32 gradually recovers its deformation and directly squeezes the metal felt limit frame 11 downward to prevent the metal felt limit frame 11 from shifting when the aluminum alloy upper mold moves upward.

[0035] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
