Hot press forming die and method thereof

Abstract

The invention discloses a hot press forming die and a method thereof. The die comprises a top end upper die, wherein side edge notches are formed in the left side and the right side of the top end upper die correspondingly, pressure reducing openings are formed in the side edge notches, a vertical rod is fixedly connected to the top end of the top end upper die, a fixed top plate is movably connected to the top end of the vertical rod, a motor is fixedly connected to the middle section of the top end of the fixed top plate, a screw rod is movably connected to the bottom end of the motor, and a clamping pressing plate is movably connected to the outer side of the bottom end of the screw rod. According to the hot press forming die and the method thereof, the pressure reduction opening can ensure that the air pressure in the die is kept balanced with the outside, it is convenient and fast to demold the die, by arranging the side notch, the splicing effect of the top end upper die is maintained conveniently, the vertical rod can increase the stability of the top end fixing top plate during use, and meanwhile, the motor can drive the screw rod to rotate; and the screw rod is helped to ascend and descend to pressurize the interior of the die, so that the forming effect in the die is improved.

Description

technical field [0001] The invention relates to the technical field of hot pressing molding dies, in particular to a hot pressing molding die and a method thereof. Background technique [0002] Thermoforming is a simple and common processing method in the plastics processing industry. It mainly uses heat to process the mold, injects the sample, fixes the model on the heating plate with pressure, and controls the melting temperature and time of the sample to achieve hardening after melting. , Cool, and then take out the finished model. Thermocompression forming can sometimes be classified as vacuum forming, and the method of applying pressure is different from compression forming. Most of the compression molding is to heat and soften the plastic in the mold, and then apply pressure to form it. The source of pressure for vacuum forming can be unilaterally evacuated, or in addition to evacuated on one side, the other side is supplemented by high pressure. Compared with other...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a thermoforming mold and its method, to solve the problem that the existing molds in the above-mentioned background technology do not have good durability when in use. The effect of hot pressing reduces the effect of mold forming, and the internal mold of the general mold is easy to be unevenly heated and cracked after not being hot pressed, which is not conducive to ensuring the yield of the mold, and the pressing effect of the general forming mold is not good. , which is not conducive to increasing the effect of mold pressing
