Description

[0002] The micro-foaming molding process mainly relies on the expansion of pores to fill the product and completes the molding of the product under a relatively low and average pressure. Micro-foaming molding can be divided into three stages. First, the supercritical fluid (CO2 or N2) is dissolved into the hot melt adhesive in the injection gun to form a single-phase solution, and it is maintained under a certain constant pressure; then, the single-phase solution is injected into the mold cavity with lower temperature and pressure through the injection gun to form a micro-foamed product, among which there are many plastic trims in automobile interiors.

When the control block 504 moves and contracts, the control block 504 pulls the winding disk 518 to start rotating, thereby opening the drain valve 414, and when the control rod 513 pushes the control rope 517 to move, the control rope 517 folds and bends.

[0045] See also Figures 5 to 8 , a transfer tube 519 is fixedly installed at one end of the temperature measuring tube 501 away from the piston rod 503, a control cylinder 520 is fixedly installed at one end of the transfer tube 519 away from the temperature measuring tube 501, and a piston block 524 is slidably installed on the inner wall of the control cylinder 520, a spring telescopic rod 521 is fixedly installed on the upper end of the piston block 524, and a threaded rod 522 is fixedly installed on the upper end of the spring telescopic rod 521. When it is necessary to adjust the detection temperature range of the temperature measuring tube 501, the threaded rod 522 is rotated to drive the threaded rod 522 to move and the piston block 524 to move, so that the spring telescopic rod 521 is squeezed, contracted or extended, so that it is more convenient to adjust the temperature range required for the temperature measuring tube 501 to be detected, and the threaded rod 522 is threaded through the upper end of the control cylinder 520, and a rotating handle 523 is fixedly installed on the upper end of the threaded rod 522. The rotating handle 523 set on the above-mentioned threaded rod 522 makes Zhai Dong's threaded rod 522 more convenient.

[0046] The working principle of the present invention is as follows: when the foaming mold 301 is used to form the material, when the temperature of the foaming mold 301 is too high, the temperature-sensitive liquid in the temperature measuring tube 501 is heated to push the piston ring 502 to start moving, so that the piston rod 503 pushes the control block 504 to start moving, and the control block 504 drives the gear rod 505 to move and insert into the hole set in the cooling valve 409, so that the gear rod 505 pushes the driven gear to start rotating, so that the valve plate 507 in the cooling valve 409 starts to rotate and open, and when the control block 504 moves, the elastic rope 516 pulls the pull rope 509 starts to move, so that the moving piece 514 starts to move and the push control handle 515 starts to rotate, so that the water outlet valve 406 opens, and the water pump 412 starts to work, and the cold water in the cooling box 413 is transferred to the cooling pipe 410 through the cooling telescopic pipe 411, and then enters the temperature control pipe 401 through the cooling valve 409. The heated water in the temperature control pipe 401 is transferred to the water outlet pipe 407 through the water outlet valve 406, and then transferred to the hot water cylinder 416 through the water outlet telescopic pipe 408, so that the foaming mold 301 is cooled more conveniently.

[0047] When the temperature of the foaming mold 301 is too low, the temperature sensing liquid causes the piston ring 502 to start to shrink, and the piston rod 503 causes the control block 504 to pull the pull rope 509, so that the pull rope 509 drives the arc block 511 to start sliding on the inner wall of the temperature rising valve 403, and the arc block 511 moves to push the control rod 513 to rotate, thereby opening the temperature rising valve 403, and the water outlet valve 406 is in a closed state. At the same time, the control block 504 pulls the pull rope 509 and pulls the control rope 517 to move, so that the control rope 517 pulls The winding disk 518 starts to rotate, the drain valve 414 is opened, and the cooling valve 409 is in a closed state, the heating pump starts to work, and the hot water in the hot water cylinder 416 is transferred to the three-way pipe 402 through the heating pipe 404, and then enters the temperature control pipe 401, so that it is more convenient to heat the foaming mold 301, so that when the foaming mold 301 is processing and molding the foaming material, the foaming mold 301 can be maintained at a suitable temperature, making the processing of the foaming material more convenient, thereby improving the working efficiency of the machine.
