DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-Figure 3A sponge seat cushion foaming mold frame includes a "return" type frame body 1, a groove 2 is opened on the top of the "return" type frame body 1, a bottom plate 3 is arranged in the groove 2, a lower mold 4 is fixedly installed on the top of the bottom plate 3, a cover plate 18 is rotatably connected to the "return" type frame body 1, and an upper mold 17 is arranged on one side wall of the cover plate 18. An auxiliary mechanism is arranged in the "return" type frame body 1, and the auxiliary mechanism includes a cylinder 11 fixedly installed on the bottom inner side of the "return" type frame body 1, a mounting plate 16 is fixedly installed on the telescopic end of the cylinder 11, two auxiliary wheels 15 are arranged on the top of the mounting plate 16, and two slots 14 are opened on the inner bottom of the groove 2;

[0020] Two cleaning mechanisms connected to the auxiliary mechanism are provided on the "return" type frame 1. The cleaning mechanism is fixedly mounted on the cylinder 8 on the side wall of the "return" type frame 1. A movable groove 10 is provided at the bottom of the groove 2. A clamping block 5 is provided in the movable groove 10 and is slidably connected to the inner wall thereof. The bottom of the clamping block 5 is rotatably connected to one end of a connecting rod 12. The other end of the connecting rod 12 is rotatably connected to the mounting plate 16. A guide rod 6 is fixedly mounted on the side wall of the clamping block 5 away from the lower die 4. A through hole 19 is provided on one inner wall of the groove 2. One end of the guide rod 6 passes through the through hole 19 and is fixedly installed with a cleaning plug 13 which is slidably connected to the inner wall of the cylinder 8. The cylinder 8 is provided with an air intake pipe 9 and an air blowing pipe 7 which are connected to its interior. Both the air intake pipe 9 and the air blowing pipe 7 are provided with a one-way valve. The ends of the air intake pipe 9 and the air blowing pipe 7 which are connected to the cylinder 8 are located on the side of the cleaning plug 13 away from the guide rod 6. The two slots 14 are located between the two movable slots 10. The two auxiliary wheels 15 are respectively adapted to the two slots 14. The cross section of the clamp 5 is an inverted "L" shape.

[0021] When the utility model is used, when it is necessary to disassemble the lower mold 4, the mounting plate 16 is moved upward by starting the cylinder 11. During the upward movement of the mounting plate 16, the two connecting rods 12 are provided to make the two clamping blocks 5 move away from each other, thereby releasing the limit on the bottom plate 3. During the process of the two clamping blocks 5 moving away from each other, the two guide rods 6 are provided to make the two cleaning plugs 13 move away from each other. The cleaning plugs 13 moving away from each other respectively produce a squeezing effect on the air in the two cylinders 8, so that the air in the cylinder 8 is blown out through the blowing pipe 7, and the blown gas is blown to the lower mold 4, which can clean the interior of the lower mold 4. For auxiliary cleaning, during the upward movement of the mounting plate 16, the mounting plate 16 also drives the two auxiliary wheels 15 to move upward. The two auxiliary wheels 15 pass through the two slots 14 respectively and contact each other with the bottom plate 3, so that the bottom plate 3 is away from the groove 2, so that the lower mold 4 can be pulled out for replacement. After the replacement is completed, the mounting plate 16 is moved downward by the cylinder 11, and the two clamping blocks 5 can be close to each other, so that the replaced lower mold 4 can be limited and fixed. At the same time, the two cleaning plugs 13 are close to each other, thereby generating a suction effect, so that the external air is sucked into the cylinder 8 through the air inlet pipe 9 for the next cleaning.

[0022] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
