The installation of sleeves, springs, pressure sensors and pressing contacts can monitor the pressure changes during the injection process in real time. When the pressure is abnormal, it can be adjusted in time to ensure the stability of the injection pressure, avoid product defects caused by pressure problems, and further optimize the injection process and improve product quality.

[0017] 3. The protective box in the dissolving component provides reliable protection for the dissolving tank. The removable protective cover on the top of the protective box forms a closed protective cavity, which effectively prevents external factors from interfering with the dissolving process, and prevents operators from contacting high-temperature components, thereby improving the safety of operation. Multiple groups of first heating modules are set on the dissolving tank, which can heat the dissolving tank evenly and stably. The wires of the heating module are protected and regulated by the wire pipe, which can control the temperature in the dissolving tank, so that the injection molding raw materials can be stably dissolved at a suitable temperature, providing good raw material conditions for the subsequent injection molding process. The stirring shaft and the stirring blade stir the raw materials in the dissolving chamber driven by the motor. The raw materials are constantly rolled in the dissolving tank and fully contacted with the heated tank wall, so that the raw materials are heated more evenly, thereby accelerating the dissolving process, and ensuring that the raw materials are dissolved more fully, avoiding the situation of partial undissolved or incomplete dissolution, improving the quality and consistency of the raw materials, and facilitating the stability of the quality of subsequent injection molding products. The connection between the feed pipe, the connecting pipe, the hopper and the dissolving chamber realizes the seamless connection between the raw material feeding and the dissolving process. The raw materials in the hopper can enter the dissolving chamber continuously and stably, and the heating and stirring functions in the dissolving tank ensure the continuity of the entire dissolving process. This not only improves production efficiency, but also ensures the stability of the quality of the dissolved raw materials, provides high-quality and stable liquid raw materials for injection molding components, and ensures the stable operation of the entire injection molding process.

[0022] like Figure 2 , Figure 3 , Fig.10As shown, the die assembly includes multiple groups of lower die supports 501 and multiple groups of lower templates 502. A mounting groove 14 is provided on the injection molding table 11. Multiple groups of lower die supports 501 can be clamped in the mounting groove 14, and these lower die supports 501 are connected to each other to form a stable and reliable support structure, which provides a basis for the subsequent injection molding process, ensures the stability of the mold during the working process, and reduces the impact of factors such as vibration on the molding quality. Multiple groups of limit blocks 503 are arranged on the top of the lower die support 501, and the lower template 502 is clamped between the limit blocks 503. The detachable connection is achieved through multiple groups of mounting bolts, which not only facilitates the installation process, so that workers can easily install the lower template 502 to a suitable position, but also facilitates the subsequent disassembly, maintenance or replacement operations. A top die electric cylinder 504 is configured below the lower template 502. The top die electric cylinder 504 is installed on the lower die support 501. As a power source, it provides a stable thrust for the demoulding process. The shaft end of the top mold electric cylinder 504 is provided with a top mold plate 505, and a plurality of groups of top mold pins 506 are provided on the top of the top mold plate 505.

[0023] The die assembly also includes a downward pressing electric cylinder 508 and multiple groups of upper templates 509. The downward pressing electric cylinder 508 is installed on the injection molding top plate 21, and it is the key driving component of the entire downward pressing action. The shaft end of the downward pressing electric cylinder 508 is provided with a mounting plate 510, and the mounting plate 510 provides a stable mounting base for subsequent components. Two groups of mounting seats 511 are provided below the mounting plate 510, and the upper template 509 is installed on the mounting seat 511, and the upper template 509 can be stuck in the molding groove 507 of the lower template 502, and a molding cavity for injection molding is formed between the upper template 509 and the lower template 502. In order to ensure the accuracy and stability of the downward pressing process, multiple groups of limit rods 512 are provided above the mounting plate 510. At the same time, multiple groups of limit through holes are opened on the injection molding top plate 21, and the limit rods 512 are inserted into these limit through holes, and one end of the limit rod 512 is connected to the mounting plate 510 by screws. When the downward electric cylinder 508 pushes the mounting plate 510 to move downward, the limiting rod 512 moves along the limiting through hole, which can effectively limit the movement trajectory of the mounting plate 510 and ensure that the upper template 509 will not deviate during the descent process, thereby keeping the shape and size of the molding cavity stable, which is beneficial to improving the molding quality of the injection molded product.

[0024] An injection molding tube 513 is arranged above the mounting seat 511, which is a key passage for the raw material to enter the molding cavity during the injection molding process. Multiple groups of injection molding holes are provided on the mounting seat 511 and the upper template 509, and the injection molding holes connect the molding cavity with the outside world to form a complete injection molding passage.

At the same time, a pressure sensor 520 is also provided in the mounting sleeve 515, and a pressing contact 521 is provided on the top of the mounting block 516. When the injection molding pressure changes, the movement of the mounting block 516 will cause the pressing contact 521 to interact with the pressure sensor 520. The pressure sensor 520 can monitor the pressure change in real time, so as to adjust the injection molding parameters in time, ensure the stability of the injection molding process, and avoid product defects caused by abnormal pressure. The pressure sensor 520 can use the MPX5700AP pressure sensor.

[0025] An air outlet duct is provided on one side of the die assembly, and the air outlet of the air outlet duct is aligned with the lower mold plate 502. A fan is installed on the injection molding table 11, and the fan is connected to the air outlet duct through an air guide duct, so that the airflow generated by the fan is ejected from the air outlet of the air outlet duct and blown to the lower mold plate 502; through the cooperation of the fan and the air outlet duct, after the raw material is injected into the molding cavity, the lower mold plate 502 is cooled to accelerate the molding of the lampshade; at the same time, a material conveyor belt is provided on the other side of the die assembly, and during the injection molding, a material conveyor belt is provided. An inclined blanking plate is installed on the table 11, the top of the blanking plate is flush with the lower template 502, and the bottom is in contact with the material conveyor belt; when the lampshade is formed, the top mold electric cylinder 504 takes the lampshade out of the molding groove 507 through the top mold needle 506. At this time, the wind force of the fan increases, and the lampshade can be blown onto the blanking plate. Through the inclined setting of the blanking plate, it can automatically roll onto the material conveyor belt, thereby completing the automatic material removal operation of the lampshade, further reducing labor costs and improving work efficiency.

[0026] like Figure 2 , Figure 4 , Figure 8As shown, the dissolving assembly includes a protective box 601 and a dissolving tank 602.

A plurality of first heating modules 605 are also provided inside the protective box 601. The first heating modules 605 are mounted on the dissolving tank 602. They are the key to providing heat for the dissolving tank 602 and can heat the dissolving tank 602 evenly and stably. The first heating module 605 can use a TC-400W-220V ceramic heating coil. On one side of the protection box 601, there are multiple groups of wire holes, and wire tubes 606 are inserted into the wire holes, and the wires on the first heating module 605 pass through these wire tubes 606. The existence of the wire tubes 606 not only protects the wires, but also makes the lines more regular, avoiding the potential safety hazards caused by disorderly wiring.

[0027] A dissolving cover plate 611 is arranged in the protective cavity, and it forms a dissolving cavity after being connected with the dissolving tank 602. A stirring shaft 612 is arranged in the dissolving cavity, and the stirring shaft 612 is rotatably connected to the dissolving tank 602. A plurality of stirring blades 613 are sleeved on the stirring shaft 612, and a motor is arranged at one end of the dissolving tank 602, and the shaft end of the motor is connected to the stirring shaft 612. When the motor is started, the stirring shaft 612 will drive the stirring blade 613 to rotate and stir the raw materials in the dissolving cavity. A feed trough 614 is provided on both the protective cover plate 603 and the dissolving cover plate 611, and a feed pipe 615 above the protective cover plate 603 passes through the feed trough 614, and a connecting pipe passes through the feed pipe 615, thereby realizing the connection between the hopper 31 and the dissolving cavity. In this way, the raw materials in the hopper 31 can smoothly enter the dissolving cavity, and under the dual effects of heating and stirring, the raw materials can be fully dissolved, providing high-quality liquid raw materials for the subsequent injection molding process.

The injection molding needle tubes 75 are direct channels for injecting liquid raw materials into the mold. The injection molding water pump 72 is located above the injection molding part 71 and is detachably connected to the injection molding table 11 for easy installation, maintenance and replacement. The injection molding water pump 72 is connected to the liquid storage tank 33 and the injection molding part 71 respectively through two sets of connecting conduits, forming a complete liquid delivery passage, ensuring that the liquid raw material can flow smoothly from the liquid storage tank 33 to the injection molding part 71, ensuring the connection between the liquid storage tank 33 and the injection molding part 71, providing a stable supply of raw materials for the injection molding process, thereby ensuring efficient and stable injection molding work; during injection molding, the electric slider 74 drives the injection molding part 71 to move, and inserts the injection molding needle 75 into the injection port 514, so that the raw material can smoothly enter the molding cavity.

[0029] like Figure 2 , Fig. 9 As shown, a liquid storage cover 35 is arranged above the liquid storage tank 32, and the two are connected to form a liquid storage cavity. The liquid storage tank 33 is located in the liquid storage cavity, and the liquid storage cavity protects the liquid storage tank 33. The liquid storage tank 33 is located at the top of the liquid storage tank 32, and a certain space is formed between the liquid storage tank 33 and the bottom of the liquid storage tank 32, which is conducive to maintaining the temperature stability of the raw materials in the liquid storage tank 33, and also facilitates the relevant maintenance operations on the liquid storage tank 33. Multiple groups of third heating modules 36 are arranged in the liquid storage cavity. The heating modules can heat the environment in the liquid storage cavity as needed to ensure that the raw materials are in a suitable temperature state, and to ensure the fluidity and injection molding performance of the raw materials. The third heating module 36 can adopt a CSH-100 water-immersed ceramic heating ring. A second water inlet pipe 37 is provided on one side of the liquid storage tank 32, and a second water outlet pipe 38 is provided on one end. The liquid storage tank 32 can be filled with water through the second water inlet pipe 37, so that the water submerges the third heating module 36, so that the third heating module 36 heats the water, generates high-temperature water vapor, and achieves the function of heat preservation and heating of the liquid storage tank 33. A sealing block is provided in both the second water inlet pipe 37 and the second water outlet pipe 38, which acts as a switch. A temperature sensor 39 is also provided in the liquid storage cavity. The temperature sensor 39 is installed in the liquid storage cover 35. It can monitor the temperature in the liquid storage cavity in real time and accurately, and provide data support for the control of the heating module, thereby ensuring the temperature control of the entire liquid storage link. The temperature sensor 39 can use a PT100 thermal resistor temperature sensor.

[0030] like Figure 2As shown, the feeding assembly also includes two groups of feeding conveyor belts 46. A fixed plate 15 is provided at one end of the injection molding table 11, and the feeding trough 41 is installed on the fixed plate 15, which builds a stable infrastructure for the entire feeding process. The two groups of feeding conveyor belts 46 are respectively installed on the two opposite inner sides of the feeding trough 41, and the two are symmetrically distributed. This layout can provide balanced and stable transmission power for the material barrel 47. Multiple groups of material barrels 47 are placed on multiple groups of rollers 42, and the rollers 42 can be flexibly rotated to facilitate the movement of the material barrels 47. One group of material barrels 47 is located below the electric lifting rod 44, and the two sides of the material barrel 47 are respectively in contact with the two groups of feeding conveyor belts 46, ensuring that the material barrel 47 will not be offset during the transmission process. An infrared sensor 48 is also provided in the feeding trough 41, which is located on one side of one group of material barrels 47 and installed on the inner side wall of the feeding trough 41. The infrared sensor 48 can monitor the position information of the material barrel 47 in real time, provide key data basis for the automatic control of the feeding process, and ensure the timeliness and accuracy of the feeding. The infrared sensor 48 can adopt the E18 - D80NK infrared sensor.

[0031] Two groups of grinding shafts are arranged in the hopper 31, and the two groups of grinding shafts are connected together by a transmission belt. Among them, one group of grinding shafts is connected to the shaft end of the grinding motor. When the grinding motor is started, the two groups of grinding shafts rotate synchronously under the action of the transmission belt. The raw materials entering the hopper 31 can be further crushed, which is helpful for the subsequent dissolution process in the dissolving component, so that the raw materials can be dissolved more fully and quickly, thereby improving the efficiency and quality of the entire injection molding production.

[0032] Embodiment 2: Based on the LED lamp cup injection molding device with a feeding structure provided in Embodiment 1 of the present application, Embodiment 2 of the present application proposes an LED lamp cup injection molding device with a feeding structure. This Embodiment 2 is only a preferred method of Embodiment 1, and the implementation of Embodiment 2 will not affect the independent implementation of Embodiment 1. Embodiment 2 of the present invention will be further described below.

[0033] like Figure 5As shown, the dissolving assembly includes a protective box 601 and a dissolving tank 602. A protective cover plate 603 is detachably provided on the top of the protective box 601. The two together constitute a relatively closed protective cavity. The dissolving tank 602 is located in this protective cavity and is well protected. A plurality of connecting brackets 604 are provided inside the protective box 601, and the dissolving tank 602 is mounted on these connecting brackets 604. A certain space is formed between the dissolving tank 602 and the bottom of the protective box 601 to avoid direct contact between the dissolving tank 602 and the bottom of the protective box 601, thereby reducing adverse effects that may be caused by heating and other factors. A plurality of first heating modules 605 are also provided inside the protective box 601. The first heating modules 605 are mounted on the dissolving tank 602. They are the key to providing heat for the dissolving tank 602 and can heat the dissolving tank 602 evenly and stably. At the same time, multiple groups of second heating modules 607 are arranged in the protection cavity, which are located below the first heating module 605 and are firmly mounted on the protection box 601. The protection box 601 is provided with a first water inlet pipe 608 and a first water outlet pipe 609, which are convenient for temperature control or other related operations inside the protection box 601. The first water inlet pipe 608 and the first water outlet pipe 609 are used to add and discharge water, so that water can be added in the protection box 601 and the second heating module 607 can be submerged. The function of the third heating module 36 arranged in the liquid storage tank 32 is not much different. The same model is used. The water is heated by the second heating module 607 to generate high-temperature water vapor, which effectively ensures the temperature in the protection cavity and is beneficial to the first heating module 605 to heat the raw materials inside the dissolving tank 602. A plurality of wire-passing holes are provided on one side of the protection box 601, and a wire-passing tube 606 is passed through the wire-passing holes. The wires on the first heating module 60 and the second heating module 607 all pass through the wire-passing tube 606, and an insulation tube 610 is provided in the wire-passing tube 606. The wires are passed through the insulation tube 610 to prevent the wires from being damaged by high-temperature water vapor, thereby improving the safety and stability of the device.

[0034] The difference between the second embodiment and the first embodiment is that a plurality of sets of second heating modules 607 are additionally provided in the protective cavity in the protective box 601. By using the first water inlet pipe 608, water can be poured into the protective box 601 so that the water covers the second heating module 607. In this way, the second heating module 607 can heat the water and generate high-temperature water vapor. This design has multiple advantages. On the one hand, the high-temperature water vapor can ensure that the protective cavity in the protective box 601 is maintained at a suitable temperature environment, creating good conditions for the dissolution of the raw materials in the dissolving tank 602 during the entire injection molding process; on the other hand, the heat generated by the water vapor can also serve as an auxiliary heating function for the dissolving tank 602, further promoting the dissolution of the raw materials, ensuring that the raw materials can be fully and evenly converted into liquid, and providing high-quality raw materials for the subsequent injection molding process. In addition, a heat-insulating tube 610 is provided in the wire-passing tube 606, and the wires on the first heating module 605 and the second heating module 607 pass through the heat-insulating tube 610. Because there is high-temperature water vapor in the protective cavity in the protective box 601, the heat-insulating tube 610 can effectively isolate the high temperature and prevent the wires from being damaged by the influence of high-temperature water vapor, thereby significantly improving the safety and stability of the entire device and reducing the risk of failure caused by line problems. The remaining conditions are consistent with those in Example 1, so this embodiment will not be repeated.
