DETAILED DESCRIPTION

[0022] The utility model makes further explanation in connection with the following description of the drawings:

[0023] As Figures 1-3 shown, the utility model relates to a mould with air top structure convenient to replace, including body 1 and through spring 2 in the inside of one end of body 1 air top core 3, the other end of body 1 is equipped with quick release assembly 4, this quick release assembly 4 is used to realize the quick installation and disassembly of air top core 3, this quick release assembly 4 includes at least one locking piece 41 fixed in the inside of the other end of body 1 through elastic buckle 40 and is equipped with the cushion 5 between locking piece 41 and air top core 3, the elastic buckle 40 is used to realize the quick disassembly of locking piece 41, the cushion 5 is used to prevent air top core 3 from rigid collision with locking piece 41 when resetting under the action of spring 2, a flow tube 42 is arranged on locking piece 41, the flow tube 42 is used to connect external air compressor, the connecting place of flow tube 42 and air compressor is equipped with a control valve 43, and the control valve 43 is used to adjust air pressure.

[0024] As Figures 1-3 shown, one side of locking piece 41 is provided with groove 410, and the cushion 5 is arranged in the groove 410, the thickness of the cushion 5 is greater than the depth of the groove 410, and the aperture of the groove 410 is slightly larger than the aperture of the cavity 10 arranged on the body 1, so that when the locking piece 41 is buckled in the body 1, the cushion 5 can be tightly attached in the groove 410.

[0025] As Figures 1-3 shown, the other end of locking piece 41 is provided with at least one first sealing groove 413, and a first sealing ring 411 is arranged in the first sealing groove 413, and the first sealing ring 411 is used to ensure the air tightness between the locking piece 41 and the body 1.

[0026] As Figures 1-3 shown, a second through hole 412 is formed in the locking piece 41, and the second through hole 412 is tightly connected with one end of the flow tube 42.

[0027] As Figures 1-3As shown, a limiting groove 11 is provided on the inner side of the other end of the body 1 near the opening. The limiting groove 11 is connected to the elastic buckle 40. The elastic buckle 40 is used to prevent the locking member 41 from being squeezed out of the body 1 by air pressure during the lifting process.

[0028] like Figures 1-3 As shown, the main body 1 has a cavity 10 inside, and the spring 2, air core 3, buffer pad 5 and locking member 41 are arranged in sequence in the cavity 10. A first through hole 13 is provided at one end of the cavity 10, and the air core 3 is provided with a telescopic end 30, which is provided in the first through hole 13.

[0029] Furthermore, a step 12 is formed in the cavity 10 within the body 1 at the junction of the air spring core 3 and the locking member 41. This step 12, in conjunction with the elastic buckle 40, keeps the locking member 41 fixed.

[0030] like Figures 1-3 As shown, the surface of the telescopic end 30 of the air crown core 3 is provided with a textured part 300, which is used to enhance the friction between the telescopic end 30 and the through hole.

[0031] Furthermore, when the telescopic end 30 extends through the first through hole 13, the reaction force of the spring 2 causes uneven force on the end face of the air ejector core 3 when it is ejected, which may lead to rotation. Therefore, increasing the surface texture of the telescopic end 30 helps to reduce the rotation of the air ejector core 3 when it is ejected, thereby avoiding damage to the molded parts on the mold due to the rotation of the air ejector core 3.

[0032] like Figures 1-3 As shown, at least one second sealing groove 301 is provided on the air core 3 near the connection of the spring 2. A second sealing ring 302 is provided in the second sealing groove 301. The second sealing ring 302 is used to ensure the airtightness between the body 1 and the air core 3. The second sealing ring 302 is usually made of wear-resistant and corrosion-resistant plastic material, which has high sealing performance and can fit tightly between the body 1 and the air core 3 to form a reliable sealing barrier.

[0033] Furthermore, when the air ejector core 3 is in the retracted state, its end face remains horizontal with the top surface of the body 1. When the mold is installed with this air ejector structure, a mounting seat 6 is fitted on the outer surface of the body, and the air ejector structure is fixedly connected to the mold through this mounting seat 6.

[0034] Assembly and working principle: firstly, the spring 2 is sleeved in the cavity 10 of the body 1, secondly, the second sealing ring 302 is sleeved in the second sealing groove 301 of the air top core 3, the telescopic end 30 of the air top core 3 is pressed into the cavity 10 of the body, so that the telescopic end 30 extends out of the first through hole 13, secondly, the first sealing ring 411 is sleeved in the first sealing groove 413 of the locking piece, the flow pipe 42 and the control valve 43 are installed through the second through hole 412 of the locking piece 41, the buffer pad 5 is arranged in the groove 410 of the locking piece 41, the end of the locking piece provided with the buffer pad 5 is pressed into the cavity 10 of the body 1 until the step 12 of the body is abutted, then the elastic buckle 40 is buckled into the limiting groove 11 of the body 1, the assembly of the air top structure is completed, when the air top structure is used in cooperation with the mold, the flow pipe 42 is communicated with the air compressor, when the product needs to be demolded, the air compressor is started, the air pressure acts on the air top core 3, the air top core 3 is pushed out along the first through hole 13, the product is separated from the mold, and the demolding is completed, at this time, the spring 2 is compressed, the air compressor is closed, the control valve 43 is opened for pressure relief, and the air top core 3 is retracted to the original position under the rebound force of the spring 2.

[0035] The above is only the preferred embodiment of the utility model, and does not limit the scope of the utility model, so equivalent changes or decorations made by ordinary engineering technicians to the structure, features and principles of the utility model without departing from the design spirit of the utility model should fall within the protection scope of the utility model.
