Description

Technical Field

[0001] The utility model relates to the technical field of steam generators, in particular to a steam generator mould of a steam box. Background Art

[0002] Steam generator, also called steam heat source machine (commonly known as boiler), is a mechanical device that uses the thermal energy of fuel or other energy sources to heat water into hot water or steam. The original meaning of pot refers to a water container heated on fire, and furnace refers to a place where fuel is burned. The boiler consists of two parts: pot and furnace. When producing steam generators, especially steam generators for steam boxes, the outer shell and some sheet metal parts need to be extruded by molds, so that the production efficiency of steam generators can be improved during production. With the development of modern technology, the functions of such production molds have gradually increased, making them more convenient to use.

[0003] In view of this, Chinese Patent No. CN208035207U proposes a steam generator mold for a steamer. The utility model adopts electromagnetic adsorption to enhance the firmness of the mold, reverses the electromagnetic circuit, and generates a force of like repulsion to help open the mold, making the mold opening process smooth and eliminating mold opening resistance. However, in the above technical solution, during the mold closing process, the upper and lower ends of the mold body will still fit together, and the mutual fit between the molds will generate friction. Long-term contact can easily cause equipment wear until it cannot be used, thereby reducing the service life of the device. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a steam generator mold for a steamer to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the utility model provides a steam generator mold for a steam box, comprising a mold base and a top plate, a buffer mechanism is arranged at the upper end of the mold base, and a cooling mechanism is arranged inside the mold base;

[0006] The buffer mechanism includes support rods fixed at the four corners of the top end of the mold base, the outer walls of the four support rods are sleeved with buffer gaskets, the outer walls of one end of the four support rods are sleeved with first springs, and one ends of the four first springs are respectively fixedly connected to the bottoms of the four buffer gaskets, connecting frames are fixedly provided on both sides of the outer wall of the mold base and both sides of the outer wall of the top plate, and two connecting rods are sleeved between the four connecting frames.

[0007] In one example, a second spring is fixedly provided on one side of the bottom of two of the connecting frames, and rubber pads are fixedly provided on the top of the other two connecting frames and the bottom of the two second springs.

[0008] In one example, the cooling mechanism includes a molding groove opened in the middle of the top end of the mold base, and an installation groove is opened on the inner wall of the mold base at the outer edge of the molding groove.

[0009] In one example, a cold water trough is inserted into the inner wall of the installation groove, and two connecting pipes are inserted into the inner wall of one end of the mold base.

[0012] The steam generator mold of the steamer proposed by the utility model can bring the following beneficial effects:

[0013] 1. The steam generator mold of the steam box is connected to the hydraulic equipment through the butt piece to squeeze the top plate down. When it drops to a certain height, it contacts the buffer gasket and the first spring is compressed to play a buffering role. At the same time, the connecting rod begins to fold as the top plate drops, so that the top plate slides on the support rod to keep the surroundings stable and not easy to deviate. When the mold is closed, the rubber pads on the two connecting frames contact and compress the second spring, so that it is not easy to generate large friction between the molds, reduce the degree of wear, and increase the service life of the device.

DETAILED DESCRIPTION

[0021] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0022] The examples are as follows:

[0023] The utility model provides Figure 1-4 The steam generator mold of the steam box shown comprises a mold base 1 and a top plate 14, and a buffer mechanism is provided at the upper end of the mold base 1;

[0024] The buffer mechanism includes support rods 2 fixed at the four corners of the top end of the mold base 1, the outer walls of the four support rods 2 are sleeved with buffer gaskets 3, the outer walls of one end of the four support rods 2 are sleeved with first springs 4, and one end of the four first springs 4 is respectively fixedly connected to the bottom of the four buffer gaskets 3, connecting frames 5 are fixedly provided on both sides of the outer wall of the mold base 1 and both sides of the outer wall of the top plate 14, and two connecting rods 6 are sleeved between the four connecting frames 5.

[0025] One side of the bottom of the two connecting frames 5 is fixed with a second spring 7, and the top of the other two connecting frames 5 and the bottom of the two second springs 7 are fixed with rubber pads 8, and torsion springs are arranged in the folding area of ​​the two connecting rods 6. When the top plate 14 descends, the connecting rods 6 fold to generate a certain torsion force, which cooperates with the first spring 4 and the second spring 7 to buffer the mold closing and reduce the wear between the molds.

[0026] Furthermore, the cooling mechanism includes a molding groove 9 provided at the middle position of the top end of the mold base 1 , and a mounting groove 10 is provided on the inner wall of the mold base 1 at the outer edge of the molding groove 9 .

[0027] A cold water tank 11 is inserted into the inner wall of the installation tank 10 , and two connecting pipes 12 are inserted into the inner wall of one end of the mold base 1 .

[0028] One end of the two connecting pipes 12 passes through the inner wall of the installation groove 10 and is connected to one side of the cold water tank 11. The other ends of the two connecting pipes 12 are fixed with a butt pipe 13. The thickness between the installation groove 10 and the molding groove 9 is relatively thin. The cold water flowing in the cold water tank 11 can quickly cool the inner wall of the molding groove 9 to assist demoulding.

[0029] Furthermore, the outer walls of the other ends of the four support rods 2 are respectively connected with the four corners of the top plate 14, the top ends of the four support rods 2 are fixed with limit blocks, and the middle position of the top end of the top plate 14 is fixed with a docking piece 15, which can be connected to an external hydraulic device to provide downward pressure to the mold.

[0030] Working principle: When using the steam generator mold of the steam box in this design, first, the top plate 14 at the upper end of the device needs to be connected through four support rods 2 so that it can slide up and down on the four support rods 2. When the steam generator sheet metal is extruded, the hydraulic equipment is connected through the docking piece 15 to squeeze the top plate 14 down. When it drops to a certain height, it contacts the buffer gasket 3 and the first spring 4 is compressed to play a buffering role. At the same time, the connecting rod 6 begins to fold as the top plate 14 drops, so that the top plate 14 slides on the support rods 2 to keep the surroundings stable and not easy to deviate. When the mold is closed, the rubber pads 8 on the two connecting frames 5 are connected. The second spring 7 is touched and compressed, so that it is not easy to generate large friction between the molds, the wear degree is reduced, and the service life of the device is increased. After molding, one of the butt joints 13 is connected to the external cold water pipe for water injection through the connecting pipe 12 into the cold water tank 11, and after flowing in the cold water tank 11 for a circle, it is led out by another connecting pipe 12, and is introduced into the water inlet again through the cold water pipe connected to the other butt joint 13 for recycling. The inner wall of the molding groove 9 is cooled by the mounting groove 10, so that the generator sheet metal formed by the mold extrusion can be quickly cooled and convenient to fall off, thereby improving the processing efficiency of the device.
