[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Reference Figure 1 、 Figure 3 and Figure 6The embodiment of the present invention provides a PPS electromagnetic shielding material forming mold, including a mold frame 1, a water tank 5 is provided inside the mold frame 1, a heat dissipation mechanism 2 is provided inside the water tank 5, and the heat dissipation mechanism 2 is used to cool the mold. A cooling mechanism 3 is provided inside the mold frame 1, and the cooling mechanism 3 is used to improve the heat dissipation effect. A lifting mechanism 4 is provided on the top of the mold frame 1, and the lifting mechanism 4 is used to eject the material in the mold; The heat dissipation mechanism 2 includes an oil pipe 21 and a belt 24. The two oil pipes 21 are respectively connected to the front and rear sides of the mold frame 1. The outer bottom of the oil pipe 21 is slidably connected to the oil pipe 22. The cooling oil in the oil pipe 21 and the oil pipe 22 can cool the device and the material when the mold frame 1 is injecting the material. The left and right sides of the bottom of the water tank 5 are rotatably connected to the electric wheels 23. The two electric wheels 23 are connected by a belt 24. The transmission of the belt 24 can improve the synchronization and stability of the rotation when the electric wheels 23 rotate. The top of the electric wheel 23 passes through the water tank 5 and A paddle 25 is fixedly connected to the top of the paddle 25, and a fan 26 is fixedly connected to the top of the paddle 25. After starting the electric wheel 23, the paddle 25 and the fan 26 thereon can be driven to rotate simultaneously. The top of the fan 26 passes through the mold frame 1. The left and right sides of the bottom of the inner bottom of the water tank box 5 are fixedly connected with metal bellows temperature compensators 27. The outer side of the metal bellows temperature compensator 27 is fixedly connected to the oil pipeline 2 22. After absorbing heat, the metal bellows temperature compensator 27 will push the oil pipeline 22 to slide along the oil pipeline 1 21. The outer side of the water tank box 5 is provided with a holding component 28, and the outside of the water tank box 5 is provided with an observation component 29; Specifically, first, the PPS electromagnetic shielding material can be injection molded on the top of the mold frame 1. During injection molding, the cooling oil in the oil pipe 1 21 and the oil pipe 2 22 absorbs heat to assist in cooling. Since the oil pipe 22 is immersed in the cooling water in the water tank 5, the heated cooling oil therein can be cooled. The electric wheel 23 is started and the rotation synchronization is improved through the belt 24 to drive the blade 25 and the fan 26 to rotate. Here, the blade 25 can enhance the cooling uniformity of the cooling water, and the fan 26 will synchronously cool the cooling water and the oil pipe 2 22. At this time, the cooling water heats up and the metal bellows temperature compensator 27 expands due to the heat, pushing the oil pipe 2 22 away from the cooling water. After the water temperature drops, it retracts and is immersed again to maintain the cooling effect.

[0023] Reference Figure 3 、 Figure 6 and Figure 7The cooling mechanism 3 comprises a bevel gear one 31 fixedly connected to the top of each fan 26, and when the fan 26 rotates, the bevel gear one 31 on it also rotates. The inner middle part of the mold rack 1 is rotationally connected with a reciprocating rod 32, and the left and right sides of the reciprocating rod 32 are fixedly connected with a bevel gear two 33. The bevel gear two 33 is meshingly connected with the bevel gear one 31, and when the bevel gear one 31 rotates, the bevel gear two 33 and the reciprocating rod 32 fixedly connected therewith also rotate synchronously. The outer left and right sides of the reciprocating rod 32 are threadedly connected with a moving block 34, and the bottom of the moving block 34 penetrates the mold rack 1 and is rotationally connected with an expansion plate 35. When the reciprocating rod 32 rotates, the two moving blocks 34 on it will continuously move left and right, thereby pushing the expansion plate 35 to rotate. The outer side of the expansion plate 35 is rotationally connected with a lifting block 36, and when the expansion plate 35 rotates, the lifting block 36 can be pushed up and down by expansion. The bottom of the lifting block 36 is rotationally connected with an expansion block 37 around the periphery, and the outer side of the expansion block 37 is rotationally connected with a wind plate 310. The top of the wind plate 310 is rotationally connected with the mold rack 1.

The outer side of the mold rack 1 is provided with a heat dissipation assembly 38, and the top of the oil pipe one 21 is provided with a cooling assembly 39. Specifically, when the fan 26 rotates, the bevel gear one 31 on it also rotates synchronously, and thereby the bevel gear two 33 meshed with the bevel gear one 31 and the reciprocating rod 32 connected therewith are rotated. The rotation of the reciprocating rod 32 will drive the moving blocks 34 on both sides to reciprocate left and right, thereby pushing the expansion plate 35 to rotate and expand, and thereby pulling the lifting block 36 at the bottom to move up and down. At this time, the expansion block 37 will rotate and push the wind plate 310 to continuously swing through its expansion. At this time, the airflow generated by the rotation of the fan 26 can flow uniformly and stably inside the device, thereby strengthening the heat dissipation effect and timely discharging the heat, avoiding the retention of steam after the evaporation of cooling water inside the device.

[0024] Referring to Figure 4 , Figure 5 and Figure 8The lifting mechanism 4 includes a mounting block 41. The two mounting blocks 41 are fixedly connected to the left and right sides of the top of the mold frame 1 respectively. The outer side of the mounting block 41 is rotatably connected to a threaded block 42. The threaded block 42 can rotate along the mounting block 41. The outer side of the threaded block 42 is threadedly connected to a positioning plate 43. The positioning plate 43 is slidably connected to the mold frame 1. Rotating the threaded block 42 along the mounting block 41 can push the positioning plate 43 to move. Hollow blocks 44 are fixedly connected to the top and sides of the mold frame 1. The inner side of the hollow block 44 is fixedly connected to a spring rod 45 The spring rod 45 is fixedly connected to the positioning plate 43. The spring rod 45 pushes the positioning plate 43 to reduce the gap between the mold or the workpiece after it is fixed, thereby reducing the probability of the mold line or burrs. The inner middle part of the positioning plate 43 is rotatably connected to a threaded rod 46. The outer side of the threaded rod 46 passes through the positioning plate 43 and is threadedly connected to an ejector plate 47. Rotating the threaded rod 46 will drive the ejector plate 47 to move along the positioning plate 43. An operating component 48 is provided on the outer side of the mounting block 41, and a positioning component 49 is provided on the outer bottom of the mold frame 1. Specifically, the position of the positioning plate 43 can be adjusted by rotating the threaded block 42 to adapt to molds or workpieces of different specifications. At the same time, the hollow block 44 and the spring rod 45 can improve the sealing when fitting the mold, effectively reducing the probability of burrs and parting lines after injection molding. After the injection molding is completed, the threaded rod 46 is rotated to drive the ejector plate 47 to move up and down. Since the ejector plate 47 will slide obliquely along the inclined positioning plate 43, the positioning of the mold or workpiece will be released, making it easier to remove the workpiece or eject it directly.

[0025] Reference Figure 1 、 Figure 2 and Figure 6 The holding assembly 28 includes a slot 281, and multiple slots 281 are respectively opened on the left and right bottoms of the sink box 5. The left and right sides of the sink box 5 are provided with handles 282. The front and rear sides of the handles 282 are fixedly connected with blocks 283. The handles 282 are engaged with the slots 281 through the blocks 283. The engagement of the blocks 283 with the slots 281 can fix the handles 282 to the outside of the sink box 5, so as to facilitate holding and carrying the device and at the same time position the sink box 5; the observation assembly 29 includes a positioning frame 291, and the two positioning frames 291 are respectively connected to the sink box 5, an observation window 292 is fixedly connected to the inner side of the positioning frame 291.

The reserved groove 210 can improve the stability of the expansion and contraction of the metal bellows temperature compensator 27, and can also facilitate the replenishment of cooling water in the water tank box 5; Specifically, by inserting the block 283 on the handle 282 into the slot 281, the handle 282 can be fixed. At this time, the water tank box 5 can be fixed in the mold frame 1 through the handle 282, and it is also convenient to hold it to carry and store the device. The observation window 292 on the inside of the positioning frame 291 can facilitate the installation and fixation of the device. The reserved groove 210 can improve the stability of the metal bellows temperature compensator 27 during extension and movement. At the same time, the reserved groove 210 can also facilitate the direct replenishment of cooling water into the water tank box 5.

[0026] Reference Figure 1 、 Figure 5 and Figure 7 The heat dissipation component 38 includes a heat dissipation groove 381, and multiple heat dissipation grooves 381 are respectively opened around the outer top of the mold frame 1. The inner side of the heat dissipation groove 381 is fixedly connected to the filter 382; the cooling component 39 includes a rubber roller 391, and the rubber roller 391 is fixedly connected to the middle part of the outer side of the reciprocating rod 32. The top of the oil pipe 21 is connected to the transmission belt 392. As the reciprocating rod 32 rotates, the rubber roller 391 will also rotate, and drive the transmission belt 392 to rotate through friction, and the heat absorption at the top of the transmission belt 392 and the heat dissipation at the bottom are used to improve the heat dissipation stability and efficiency. Specifically, the heat dissipation groove 381 can allow air flow to enter the interior of the device for ventilation and heat dissipation, and the filter 382 can prevent impurities and dust from entering the device along with the air flow. When the reciprocating rod 32 rotates, the friction and rotation of the rubber roller 391 thereon can cause the transmission belt 392 to rotate on the top of the oil pipeline 21. The top of the transmission belt 392 will absorb the heat of the mold frame 1 and be cooled by the rotation of the fan 26 when it is transmitted to the bottom, thereby further improving the efficiency and uniformity of heat dissipation.

[0027] Reference Figure 4 、 Figure 5 and Figure 8 , the operating component 48 includes a knob 481, which is fixedly connected to the outer side of the mounting block 41, the outer side of the knob 481 passes through the mounting block 41 and is fixedly connected to the threaded block 42, the outer side of the threaded rod 46 passes through the positioning plate 43 and is fixedly connected to the knob 2 482, and the threaded block 42 and the threaded rod 46 can be respectively operated to rotate by rotating the knob 1 481 and the knob 2 482; the positioning component 49 includes a positioning block 491, and a plurality of positioning blocks 491 are respectively fixedly connected to the outer bottom of the mold frame 1 around, and a positioning hole 492 is opened on the outer side of the positioning block 491, and the device can be easily fixed by inserting a screw into the positioning hole 492; Specifically, by turning knob 1 481, the threaded block 42 can be driven and operated to rotate synchronously, and by turning knob 2 482, the threaded rod 46 can be driven and operated to rotate synchronously. By inserting a threaded part into the positioning hole 492 outside the positioning block 491, the device can be installed and fixed by the threaded part.

[0028] Working principle: PPS electromagnetic shielding material can be injection molded on the top of the mold frame 1. During the injection molding process, the cooling oil in the oil pipe 1 21 and the oil pipe 2 22 absorbs heat for cooling. Since the oil pipe 22 is immersed in the cooling water in the water tank 5, the cooling oil in the oil pipe 22 that becomes hot due to absorbing heat can be cooled. At the same time, the electric wheel 23 is started and the belt 24 is used to improve the rotation synchronization, thereby driving the blade 25 and the fan 26 to rotate. The rotation of the blade 25 will improve the cooling uniformity of the cooling water, and the fan 26 can cool the cooling water and the oil pipe 2 22 synchronously. At this time, since the cooling water will also be heated, the heated water temperature will cause the metal bellows temperature compensator 27 to expand due to the heat, pushing the oil pipe 2 22 away from the cooling water, and retracting it after the cooling water cools down to allow it to be immersed again to maintain the cooling effect. As the fan 26 rotates, the bevel gear 1 31 on it also rotates, and as the bevel gear 1 31 rotates, it drives the bevel gear 2 33 meshing with it and the reciprocating rod 32 on it to rotate. At this time, as the reciprocating rod 32 rotates, it drives the moving block 34 to move left and right, thereby pushing the telescopic plate 35 to rotate and retract, pulling the lifting block 36 at the bottom to move up and down, causing the telescopic block 37 to rotate and retract, pushing the wind plate 310 connected to it to swing continuously, so that the airflow when the fan 26 rotates can circulate evenly and stably throughout the entire device, thereby improving the heat dissipation effect inside the device, discharging heat in time, and preventing steam from evaporating cooling water from remaining in the device. Finally, by rotating the threaded block 42 along the mounting block 41, the position of the positioning plate 43 can be adjusted to adjust molds or workpieces of different specifications. At the same time, the hollow block 44 and the spring rod 45 can push the sealing degree during fitting to reduce the probability of burrs and parting lines after injection molding. After injection molding, the threaded rod 46 can be rotated to drive the ejector plate 47 to move up and down. Since the ejector plate 47 will move obliquely along the inclined positioning plate 43, the ejector plate 47 will release the positioning of the mold or workpiece, making it easy to remove or directly eject the workpiece.
