| titleOfInvention | Secondary molding frame (mold) of integrally molded air cushion body |
| abstract | The present invention relates to a secondary molding die (mold) structure of a kind of integrally molded air cushion body. One mold hole is provided in each of the upper and lower molds of the mold, and a hollow hole extending to the outside of the mold is formed at one end of the mold hole. Its main part is to dig one groove type at each end of the upper and lower molds in contact with each other, make one iron lump in each groove type, and then install a spring between the iron lump and the groove type, and in the groove type Where the iron tube and the hollow hole are in contact with each other, the insertion hole having the same diameter length as the hollow hole is also drilled. With this in mind, when the primary molded elastic material is enclosed in the cylindrical PU inclusions and the mold is fastened, the PU inclusions are immediately compressed to become air sacs, and the iron masses between the upper and lower dies press on each other at the same time. Continue to pressurize and swell the air sacs when the air inside it expands outward at the pressure of space contraction, so that it is in close contact with the inside of the mold cavity, forming. In this way, the integral air cushion body is secondly molded and the manufacturing process and the production cost can be realized. |
