[0016] 1. The punching device with shock-absorbing function is used for the mold processing. When the pressing mold descends and is misaligned with the material-containing mold, the pressing mold contacts the detection plate. At this time, the weight sensor inside the detection plate operates to stop the pressing mold from pressing down, which is beneficial to avoid damage to the surface of the material-containing mold.

[0018] 3. The stamping device with a shock-absorbing function is used for the mold processing. The first sponge brush and the second sponge brush can absorb the lubricating oil and apply it to the lower surface of the pressing mold and the inner surface of the material tank. Then, the PC plastic material is stamped and formed. After the shell is formed and solidified, the shell can be easily taken out based on the lubricating effect of the lubricating oil to avoid adhesion between the shell and the pressing mold or the material tank;

[0019] 4.

[0020] 5.

[0028] The specific operation is as follows: the material holding mold 3 carries the melted PC plastic material and moves to the bottom of the pressing mold 6 through the conveyor belt 2. The pressing mold 6 is pressed down by the hydraulic cylinder 5 into the material holding trough 4 to stamp and shape the PC plastic material. The spring damping rods 7 are evenly distributed around the material holding mold 3. When the pressing mold 6 deviates from the material holding trough 4 during the pressing process, the pressing mold 6 will be attached to the surface of the detection plate 8. At this time, the spring damping rods 7 are forced to contract to reduce the pressure on the detection plate 8, which plays a role in shock absorption and unloading. At the same time, the weight sensor 9 stops pressing the pressing mold 6 due to the force operation, which is beneficial to avoid damage to the surface of the material holding mold 3. The top and bottom ends of the telescopic fence 10 are fixedly connected to the detection plate 8 and the material holding mold 3 respectively, and the telescopic fence The fence 10 is set as a telescopic structure, which is distributed parallel to the detection plate 8 and the material holding mold 3, and a telescopic fence 10 is set in the gap between the detection plate 8 and the material holding mold 3. The telescopic fence 10 closes the gap to prevent PC plastic material from flowing into the gap, and the telescopic fence 10 can be retracted when the detection plate 8 is stressed, which is conducive to the normal operation of the detection plate 8. Lubricating oil is stored in the first oil pump box 12, and the lubricating oil is transported to the first sponge brush 13 along the pipeline through the pump body inside the first oil pump box 12. The first sponge brush 13 absorbs the lubricating oil and extends through the first horizontal push rod 11. At this time, the first sponge brush 13 will apply the lubricating oil to the lower surface of the pressing mold 6, which is conducive to making the outer shell easy to separate from the pressing mold 6 after solidification due to the lubricating oil, avoiding The shell is adhered to the surface of the pressing die 6, and the first sponge brush 13 is retracted from the position of the pressing die 6 by the first horizontal push rod 11 after the application is completed, so as not to affect the lifting and lowering of the pressing die 6 for stamping operation. The sponge box 17 is rotated to the top of the second horizontal push rod 15 by the servo motor 16 in an idle state, which is conducive to saving space and facilitating the passage of the material-containing die 3. After the second sponge brush 19 rotates, the excess lubricating oil absorbed by it drips into the oil storage tank 18 of the sponge box 17, preventing the lubricating oil from dripping randomly. When the second sponge brush 19 is used for the next time, the excess lubricating oil will fall back to the second sponge brush 19 and be absorbed by it, which is conducive to saving lubricating oil and avoiding waste. Moreover, when the lubricating oil slides to the surface of the second sponge brush 19, it is The block 21 can prevent the lubricating oil from sliding out of the sponge box 17 along the inner wall of the oil storage tank 18, so that the lubricating oil can completely drip onto the surface of the second sponge brush 19. When the second sponge brush 19 applies lubricating oil to the material holding mold 3, the sponge box 17 rotates to make the second sponge brush 19 face the material holding mold 3. At this time, the lifting push rod 14 cooperates with the second horizontal push rod 15 to make the second sponge brush 19 slide on the inner surface of the material holding tank 4. At the same time, the lubricating oil inside the second oil pump box 22 enters the sponge box 17 and the porous hose 20 along the pipeline in turn to reach the inside of the second sponge brush 19 and be absorbed by it, thereby realizing the lubricating oil smearing on the inner surface of the material holding tank 4. The porous hose 20 with microporous surface is evenly distributed in the second sponge brush 19, which is conducive to the second sponge brush 19 to evenly absorb the lubricating oil.

[0029] In summary, the punching device with a shock-absorbing function for mold processing is used. First, the material-containing mold 3 is moved to the position of the second sponge brush 19 through the conveyor belt 2. At this time, the sponge box 17 is rotated by the servo motor 16, so that the second sponge brush 19 faces the material-containing mold 3, and then the lifting push rod 14 and the second horizontal push rod 15 cooperate to make the second sponge brush 19 slide against the inner surface of the material-containing tank 4. At the same time, the lubricating oil inside the second oil pump box 22 enters the sponge box 17 and the porous hose 20 along the pipeline in turn to reach the inside of the second sponge brush 19 and is absorbed by it, thereby realizing the lubricating oil coating on the inner surface of the material-containing tank 4;

[0030] Then the material holding mold 3 continues to move to the material receiving position via the conveyor belt 2, at which time the melted PC plastic material is injected into the material holding tank 4, and then the material holding mold 3 moves again to the bottom of the pressing mold 6;

[0031] During the movement of the material holding mold 3, the lubricating oil is transported to the first sponge brush 13 along the pipeline through the pump body inside the first oil pump box 12. The first sponge brush 13 absorbs the lubricating oil and extends through the first horizontal push rod 11. At this time, the first sponge brush 13 will apply the lubricating oil to the lower surface of the pressing mold 6. When the pressing mold 6 is pressed down by the hydraulic cylinder 5, if the pressing mold 6 and the material holding tank 4 are offset, the pressing mold 6 will be attached to the surface of the detection plate 8. At this time, the spring shock absorber rod 7 is forced to contract to reduce the pressure on the detection plate 8, which plays a role in shock absorption and unloading. At the same time, the weight sensor 9 stops pressing the pressing mold 6 due to the force operation, which is conducive to avoiding damage to the surface of the material holding mold 3.

[0032] The stamping operation can be realized when the position of the material holding mold 3 is adjusted by the conveyor belt 2 so that the pressing mold 6 is smoothly pressed into the material holding tank 4. Then, after the shell is formed and solidified, the pressing mold 6 rises. Since the lower surface of the pressing mold 6 and the inner surface of the material holding tank 4 have lubricating oil, the shell can be prevented from sticking, thereby facilitating the material removal.

[0033] Finally, the sponge box 17 is rotated to the top of the second horizontal push rod 15 by the servo motor 16 in an idle state, which is conducive to saving space and facilitating the passage of the material-containing mold 3. After the second sponge brush 19 rotates, the excess lubricating oil absorbed by it drips into the oil storage tank 18 of the sponge box 17 to prevent the lubricating oil from dripping randomly. When the second sponge brush 19 is used for the next time, the excess lubricating oil will fall back to the second sponge brush 19 and be absorbed by it, which is conducive to saving lubricating oil and avoiding waste.
