The first end of the inner pressurizing pipe 103 is fixedly connected with the first end of the pressurizing pipe 102, the second end of the pressurizing pipe 102 is fixedly connected to the pressurizing box 101, the pressurizing box 101 is fixedly connected to the cross supporting frame 113, the second end of the inner pressurizing pipe 103 is provided with an opening, the inner pressurizing pipe 103 is provided with an annular supporting block, and the outer sliding rod 108 is supported through the annular supporting block to avoid deflection of the outer sliding rod 108.
As shown in fig. 6, when the resin molding machine is used, the first resin material is heated by the first conveying box 110, then the switch on the middle supporting frame 112 is turned on, the first resin material is conveyed into the lower conveying pipe 115 by the middle supporting frame 112, flows into the space surrounded by the upper die 201, the lower die 202 and the middle die 203 by the lower conveying pipe 115, after the resin is quantitatively conveyed, the switch on the middle supporting frame 112 is closed, the pressurizing box 101 is started, gas enters the inner pressurizing pipe 103 through the pressurizing pipe 102 and flows out from the opening at the second end of the inner pressurizing pipe 103, so that the air pressure of the space between the inner pushing plate 116 and the sealing cover 109 is increased, the inner pushing plate 116 is pushed to move downwards in the lower conveying pipe 115, and the resin which does not fall or remains in the lower conveying pipe 115 is extruded and completely enters the space between the upper die 201 and the lower die 202.
In the process that the inner push plate 116 moves downwards, the inner push plate 116 pulls the second end of the outer slide bar 108, and the first end of the outer slide bar 108 drives the upper transverse frame 104 to move downwards, so that the upper transverse frame 104 pushes the upper vertical slide bar 105 to move downwards, the upper vertical slide bar 105 slides on the lower vertical slide bar 107 and presses the lower spring 106 on the lower vertical slide bar 107, so that the second end of the lower vertical slide bar 107 is pushed by the reaction force of the lower spring 106, and the lower vertical slide bar 107 pushes the upper die 201 again, so that the upper die 201 and the lower die 202 are more compact, and the problems of shaking and the like caused by a pressure die are avoided.
When the first resin solution is added and is uniformly pressurized, the upper mold 201 and the lower mold 202 are controlled to move downwards, and the lower vertical slide bar 107 is pulled to move downwards, at the moment, the pressurization is not cancelled, a large amount of air is still present between the outer slide bar 108 and the inner slide bar 116, so that the lower spring 106 is still compressed, when the lower vertical slide bar 107 moves downwards, the lower spring 106 stretches, the shaking component 5 controls the mold bottom plate 204 to vibrate so as to further promote the uniform distribution of the solution, after the end, the upper mold 201 and the lower mold 202 are upwards, at the moment, the upper mold 201 and the lower mold 202 are not reset to the initial position, but are at a distance from the initial position, then the air between the inner slide bar 116 and the sealing cover 109 is reduced through the pressurization box 101, the inner slide bar 116 is driven to move upwards, the inner slide bar 116 is reset, and when the upper vertical slide bar 105 reaches the initial position quickly, the lower spring 106 is changed to be in a free state from the extruded state, the upper vertical slide bar 105 is stretched, the lower slide bar 201 and the upper mold 201 are pulled to move upwards, and a new resin is added between the upper mold 201 and the lower mold 202 through the intermediate mold 203, and the second resin is formed, or the intermediate space is formed between the intermediate mold and the second resin mold and the third space. Therefore, the co-molding of various resin materials is realized, the stability of connection among the various resin materials is ensured, and the problems of unstable connection in the later period and the like are avoided.
